Abstract

In a conventional tool storage method and apparatus in which a cylindrical object is provided in a round hole opened in a shelf, and a tool is inserted and stored one by one in the cylindrical object, the cylindrical object is a shank of the tool. Since it has come into close contact with only the part, it is necessary to prepare a cylindrical object with a different shape every time the tool is different. Therefore, there is a problem that many shapes of cylindrical objects must be prepared. It was.
SOLUTION: A large-diameter disk part between a shank part and a blade part of a tool is accommodated in a cylindrical object so as to be in close contact with the inner wall surface of the cylindrical object. The lower part is brought into contact with the cylindrical object, but when the shank is short, the lower part is not brought into contact with the cylindrical object. Reduce the type of tube.

Description

  The present invention relates to a tool storage method and apparatus. In particular, the present invention relates to a simple method and apparatus for safely storing various tools used for lathes, milling machines, boring machines, drilling machines, etc., so-called tools in a machine factory.

  Various tool storage devices are already known. Among them, a lot of shelves are used. A shelf-type tool storage device is a type in which support columns are erected on the left and right, a shelf is placed between them, a number of round holes are made in the shelf, and one tool is stored in each of the round holes. belongs to.

  In a shelf-type tool storage device, both the support column and the shelf plate are often made of steel plates. Using a steel shelf board to make a round hole in the shelf board and inserting the tool directly into the round hole not only makes it difficult to house the tool in the hole without looseness, but also damages the tool edge. Therefore, a cylindrical member for buffering is attached to the round hole, and the tool is accommodated in the shelf board via the cylindrical member.

  On the other hand, there are various tools having different shapes and sizes. The tool storage device must be capable of safely storing all such tools having different shapes and sizes. On top of that, many of the tools are made of special steel and are heavy. Therefore, in order to store the tool safely and reliably, it becomes a problem which part of the tool is supported by the cylindrical object.

  In general, a tool is formed in a shape in which a cutting blade portion and a shank portion to be attached to a machine tool such as a lathe are integrated. The size and shape of the blade part vary greatly depending on the type of tool, but the shank part is a part for gripping various machine tools, so it is standardized by JIS and the shape does not change much. . For this reason, the cylindrical object is formed in such a manner that only the shank part of the tool is inserted and the remaining part of the tool is protruded. Moreover, in order to prevent the tool from rattling in the cylindrical object, the inner surface of the cylindrical object is made in close contact with the shank. Therefore, in the conventional storage device, a different cylindrical object must be used every time the tool is different.

  Japanese Patent Application Laid-Open No. 10-29176 describes an improved version of the above device, but there is no change in that the device uses a different cylindrical object for each different tool. That is, in the apparatus of this publication, a cylinder is inserted into a round hole opened in the shelf board and locked to the shelf board with a scissors, and only the shank portion of the tool is inserted into the cylinder, and the tool is inserted. I try to store it. When inserting a tool with a shank part with a different inclination into the cylinder, insert a flexible adapter prepared separately to fill the gap generated in the cylinder and insert the tool without play. I have to. Thus, it is very cumbersome to use different cylinders or adapters for different tools.

  Utility Model Registration No. 3060743 has a storage cylinder in a round hole attached to a shelf board, and the storage cylinder is provided with a flat plate-like collar at one end and a bottom at the other end. Same size from bottom to bottom. Such a storage cylinder is attached with being tilted together with the shelf so that the bottom is as far as the bottom. And the shank part of a drill is deeply sunk in this storage cylinder, Furthermore, even a part of blade part is inserted in a storage cylinder, and the stable storage is measured. However, this publication only exemplifies a case where a drill having the same shape is accommodated, and does not accommodate a tool having a different shape.

  Utility Model Registration No. 3083651 and No. 3095640 describe a device for making a circular hole in a shelf plate, attaching an annular holding portion around the round hole, and inserting a tool into the holding portion. is doing. However, since the structure of the holding portion is not described, it is not considered that the holding portion can store various tools having different shapes without looseness.

Thus, in order to stably store tools of different shapes, a cylindrical object having an inner surface that is in close contact with the shank part of each tool is made, and the shank part of the tool is brought into close contact with the cylindrical object. I came. Therefore, when the shank part of the tool has a different inclination, there is an inconvenience that a cylindrical object matching the inclination must be prepared for each tool.
JP-A-10-29176 Utility Model Registration No. 3060743 Utility model registration No. 3083651 Utility Model Registration No. 3095640

  The object of the present invention is to eliminate the above-mentioned inconvenience associated with the conventional tool storage device. That is, in the present invention, as in the conventional apparatus, a tool is stored by attaching a cylindrical object in a round hole formed in a shelf plate. In this case, a separate cylindrical object is used for each tool. And a tool storage method and a method in which several types of tools are stored in the same cylindrical object so that the number of types of cylindrical objects to be used is reduced, and thus various types of tools can be easily stored. The device is to be provided.

  Originally, as described above, the tool includes the blade portion and the shank portion, but further includes a disk portion protruding laterally therebetween. More specifically, the tool includes a disk portion having a diameter larger than the diameter of the truncated cone on the way from the truncated cone-shaped shank portion to the blade portion. A step portion perpendicular to the axial direction is formed on the side of the disc portion facing the shank portion. In the above-mentioned Japanese Patent Application Laid-Open No. 10-29176, this step portion is placed on the tub of the cylindrical object so that only the shank portion is accommodated in the cylindrical object.

  This inventor puts the above-mentioned disk part of the tool in a cylindrical object, brings the circumferential surface and the step part of the disk part into close contact with the inner wall of the cylindrical object, and mainly uses the disk part for the tool. An attempt was made to stably store in a cylindrical object. Then, paying attention to the fact that there are many types of tools with very close outer diameters of the disk part, with the outer diameter of the disk part as a reference, those with close outer diameters as one group, We considered reducing the types of necessary cylindrical objects by storing tools belonging to this group in a single cylindrical object.

  For that purpose, it is necessary to provide a large-diameter disk-shaped cavity at the opening of the cylindrical object, and to provide a step for supporting the lower surface of the tool disk at the lower end of the cavity. I realized that. Therefore, the cylindrical object is not provided with a flat plate-like ridge as in the prior art, but is provided with a cocoon having a large thickness in the axial direction of the cylindrical object, and a space in which the disk portion of the tool can be accommodated in the ridge, and the lower surface of this space The present inventors have found that it is necessary to make the structure provided with a step portion. Moreover, in order to hold | maintain a tool stably, it discovered that the step part of a cylindrical thing needed to be located above the upper surface of a shelf board. Further, it has been found that the outer peripheral edge of the stepped portion is preferably located directly above the peripheral edge of the round hole or slightly outside the peripheral edge of the round hole.

  Also, it is necessary to provide a cylindrical hanging part in the cylindrical object to put the shank part of the tool as in the conventional case, but when the shank part extends long in the axial direction from the disk part, the hanging part is The shank part needs to be supported by a cylindrical object. However, when the shank part is short in the axial direction, it has been found that the shank part can be stably held without being supported by the cylindrical object.

  In this way, the present invention groups, as a group, ones having substantially the same outer diameter of the disk portion from among a variety of tools, and creates one cylindrical object for each tool belonging to the same group, Each cylindrical object has a structure in which the collar part and the hanging part are integrated, and the collar part accommodates the disk part of the tool, and the step part that supports the inner surface close to the disk part and the lower surface of the disk part The hanging part hangs down from the inner end of the step part, and when the shank part is long in the axial direction, it contacts the surface of the shank part, but when the shank part is short in the axial direction, the shank part The present invention provides a method for storing a tool, wherein the tool is stored in a cylindrical shape that matches the outer diameter of the tool disk portion, and has a shape that does not require contact.

  Here, the shank portion being long in the axial direction means that the axial length of the shank portion is equal to or larger than the maximum outer diameter on the basis of the maximum outer diameter of the shank portion. That the portion is short in the axial direction means that the axial length of the shank portion is smaller than the maximum outer diameter.

  In this invention, the disk part outer diameter of a tool is substantially equal means that when the maximum value of the disk part outer diameter belonging to one group is X, there is a difference of 1/100 or less of X. Refers to including things.

  In addition, in order for the cylindrical object to securely hold the tool at its disk part, it is desirable that the cylindrical object has dropped deeply into the disk part and that the width of the step part is large. However, if it is dropped too deeply, it will be difficult to remove the tool from the cylindrical object, and if the width of the step is too large, the shank part cannot be inserted into the hanging part of the cylindrical object. According to experiments, it is sufficient that the depth is about 20 mm in absolute value. In terms of relative values, the axial length of the portion of the cylindrical object that accommodates the tool disk portion (hereinafter referred to as the opening portion) is 15-30% of the maximum value Y of the inner diameter of the opening portion. It is preferable to be within the range. Further, it is preferable that the width of the stepped portion is within a range of 8 to 12% of the maximum value Y. Here, the reason why the maximum value Y of the inner diameter is expressed is that it includes a case where the opening portion is not exactly a cylinder but a conical portion with a slight depression. When the opening has an accurate cylindrical shape, the maximum value Y is equal to the diameter X described above.

  Synthetic resin is suitable as the material constituting the tube, and it is particularly suitable to use polyamide (nylon), polyethylene, and polypropylene.

  Moreover, this invention provides the tool storage apparatus in another surface. In the device, a shelf is placed between the right and left columns, and a number of round holes are made in the shelf, and a cylindrical cylinder made of synthetic resin is attached to the inside of the round hole. In the tool storage device that stores tools one by one, the above cylindrical object has a structure in which the collar part and the hanging part are integrated, and the collar part is connected to the outer cylinder part and the inner cylinder part at the upper end. In addition to the double cylinder structure, the inner cylinder portion is provided with a stepped portion that protrudes to the inside of the tube at a position above the lower end of the outer tube portion, and has a shape that continues to the hanging portion below the stepped portion. The part has a cylindrical shape at the top, a step part that protrudes into the cylinder in the middle, and a conical surface with a concavity in the lower part, and a cylindrical object with the outer cylinder part in contact with the shelf. It is characterized by being attached.

  When the shank part of the tool is long in the axial direction, a part of the hanging part is brought into contact with the shank part, and when the shank part is short in the axial direction, the upper part of the hanging part is prevented from coming into contact with the shank part. It is preferable that the length of the cylinder formed in the axial direction is 70 to 90%, particularly 80 to 90% of the maximum value Z of the cylinder inner diameter. Further, it is preferable that the width of the step provided at the lower end of the cylinder is in the range of 15 to 30% of the maximum value Z.

  According to the method of the present invention, the cylindrical object is not made according to the shape of the tool shank part, but is made according to the shape of the tool disk part, and the drooping part of the cylindrical object has the shank part in the axial direction. When it is long, a part of the hanging part is brought into contact with the shank part. However, when the shank part is short in the axial direction, it is not necessary to bring the hanging part into contact with the shank part. can do. Further, when the tool is stored in the apparatus, the tool can be stored easily because it can be inserted based only on the outer diameter of the opening of the cylindrical object.

  According to the device of the present invention, the cylindrical object has a structure in which the collar part and the hanging part are integrated, and the collar part has a double structure in which the outer cylinder part and the inner cylinder part are connected at the upper end. The resin material can be reduced to form a large opening, and the inner cylinder is provided with a step that protrudes to the inside of the cylinder at a position above the outer cylinder. The plate portion can be inserted and the lower surface of the disc portion can be brought into contact with the stepped portion to accommodate the disc portion of the tool in a stable state.

Further, according to the device of the present invention, the eaves portion has a shape that is continuous with the hanging portion below the step portion, the hanging portion has a cylindrical upper portion, and a step portion projecting into the cylinder in the middle, and if necessary below the step portion. Since it has a shape with a conical surface with a lower concavity, when the shank is long in the axial direction, the step or end surface existing in the shank is brought into contact with the step, or the lower part of the shank is conical. It can be made to contact | abut, and a tool can be accommodated as a stable state by this. In addition, according to the present invention apparatus, since the tool is accommodated mainly by putting the disk portion of the tool into the collar portion, the types of cylindrical objects can be reduced.
The present invention provides such an effect.

  An embodiment of the present invention will be described below with reference to the drawings. In the drawings, FIG. 1 is a perspective view of a tool storage device according to the present invention. FIG. 2 is a perspective view showing the relationship between a cylindrical object and a shelf board used in the present invention. FIG. 3 is a longitudinal sectional view when the cylindrical object according to the present invention is attached to the shelf board. 4-7 is sectional drawing of the state in which the tool was accommodated in the cylindrical object used by this invention.

  As shown in FIG. 1, the tool storage device according to the present invention has a shelf plate 3, 4 between the columns 1 and 2 erected on the left and right sides, and a circular hole 5 in the shelf plate 3, 4. A cylindrical member 6 made of synthetic resin is attached around the round hole 5, and tools are inserted into the cylindrical member 6 one by one and stored. The shelf 3 is fixed between the columns 1 and 2, but the shelf 4 is not fixed and can be pulled out along a rail (not shown) fixed to the columns 1 and 2.

  The shelf board may be a board having a large depth as shown in FIG. 1 and provided with a plurality of rows of round holes, but as shown in FIG. It may be a small plate provided with a single row of round holes therein.

  As shown in FIG. 2, the cylindrical object 6 is formed by integrally forming a large-diameter cylindrical flange 61 and a small-diameter substantially cylindrical hanging part 62 with a synthetic resin. The tubular body 6 is attached by hanging the hanging portion 62 into a round hole formed in the shelf 3 and locking the collar portion 61 around the round hole 5. Therefore, when the shelf board 3 is viewed from above, only the flange 61 appears to protrude.

  As shown in an enlarged view in FIG. 3, the representative cylindrical member 6 is made of synthetic resin polypropylene in a shape in which the flange portion 61 and the hanging portion 62 are integrated. If it says on the shelf board 3, the shelf board 3 is supporting the cylindrical object 6, in the state which contact | abutted the lower end of the outer side cylinder part 611. FIG. The actual dimensions of the cylindrical object 6 are such that the length of each part shown in FIG. 3 is approximately the size (unit: mm) shown in Table 1 below.

  As shown in FIG. 3, the flange portion 61 has a double cylindrical structure. That is, the flange portion 61 is formed by integrally forming the outer cylinder portion 611, the inner cylinder portion 612, and the connection portion 613 that couples the upper ends thereof, and between the outer cylinder portion 611 and the inner cylinder portion 612. A gap is formed. In this gap, a bridging portion that connects the outer cylinder portion 611 and the inner cylinder portion 612 is formed in some places, thereby strengthening the double cylinder structure. In addition, a step portion 614 that protrudes into the cylinder is formed in the inner cylinder portion 612 at a position above the lower end of the outer cylinder portion 611. Further, a cylindrical portion 615 that hangs down in the cylinder is attached to the inner end of the step portion 614, and the lower end of the cylindrical portion 615 is gently connected to the hanging portion 62.

  As shown in FIG. 3, the hanging portion 62 is formed in a shape in which a cylindrical portion 621, a stepped portion 622, and a conical portion 623 are integrally connected in order from the top. The cylindrical portion 621 is gently connected to the cylindrical portion 615 as described above. The step portion 622 projects into the cylinder, and a conical portion 623 is attached to the inner end of the step portion 622, and the conical portion 623 has a shape of a downward depression.

  Since the cylindrical object 6 has the above-described structure, it is possible to safely store a tool having a different shape with the same one-shaped cylindrical object without looseness. For example, when four types of tools such as NT-50, HSK-100, KM-100, and NC5-100 are taken as tools, these tools have disk portions having substantially the same outer diameter (about 100 mm). For this reason, these tools can be housed in a stable state in the same cylindrical object 6 in which the inner diameter of the opening shown in FIG.

  Specifically, the tool NT-50 has a disk portion P having a diameter of 100 mm and an axial length of 12 mm, a large diameter of 69.85 mm, a small diameter of 39.6 mm, and an axial length of 101.8 mm. And a shank portion A having a cylindrical portion having a diameter of 39.6 mm and an axial length of 28.2 mm below it, and a blade portion not shown above the disk portion P As shown in FIG. 4, the cylindrical object 6 has the circular plate portion P abutted against the inner cylindrical portion 612 and the stepped portion 614, and the lower portion of the shank portion A is connected to the conical portion 623. The tool NT-50 can be accommodated in a stable state by contact or approach.

  The tool HSK-100 has a disc portion Q having a diameter of 100 mm and an axial length of 29 mm, and a shank portion B having a diameter of 75 mm and a width direction length of 50 mm. As shown in FIG. 5, the cylindrical object 6 is provided with a blade part (not shown) on the upper side, and the disk part Q is brought into contact with the inner cylinder part 612 and the step part 614, as shown in FIG. 5. Contains -100. Since this tool does not reach the conical part 623 because the shank part B is short, it has been found that the shank part B can be stably held close to the hanging part 62 without contacting the shank part B with the hanging part 62. is doing. Accordingly, it is not necessary to bring the shank part B into close contact with the hanging part 62.

  In addition, the tool KM-100 includes a disc portion R having a diameter of 100 mm and an axial length of 34 mm, and a shank portion having a large diameter of 82 mm and an axial length of 50 mm and a one-tenth inclination. C, and provided with a blade portion (not shown) above the disc portion R, the cylindrical object 6 has the disc portion R and the inner cylinder portion 612 as shown in FIG. The tool KM-100 is accommodated in contact with the step portion 614. Like the tool HSK-100 shown in FIG. 5, this tool is not inserted into the conical portion 623 because the shank portion C is short, so that the shank portion C does not have to contact the hanging portion 62. It can be held in a stable state.

  In addition, the tool NC5-100 has a disc portion S having a diameter of 100 mm and an axial length of 38 mm, and a large diameter of 76 mm and an axial length of 57 mm, and has an inclination of a lower recess of 1/10. A shank comprising a conical portion and a cylindrical portion having a diameter of 70 mm and an axial length of 11 mm below the conical portion, and a thick cylindrical portion having a diameter of 35 to 25 mm and an axial length of 48 mm below the conical portion The cylindrical object 6 has a part D and a blade part (not shown) above the disk part S. As shown in FIG. And the step portion 614, and the step portion E existing in the shank portion D is brought into contact with the step portion 622 provided in the hanging portion 62 to accommodate the tool NC5-100. Since the shank portion D of this tool is long, it has entered the conical portion 623, but the step portion E comes into contact with the step portion 622, so that the tool is stably held in the cylindrical object 6.

  As described above, taking four types of tools as an example, the present invention makes a group of tools having substantially the same diameter of the disk portion, and the cylindrical object that accommodates these tools has the same inner diameter of the opening. In addition, a step portion is provided at a position where the disk portion can sufficiently sink, and the step portion is positioned above the shelf plate to form the collar portion. At the same time, the present invention provides a hanging portion that accommodates the shank portion, but the short shank portion is not in contact with the hanging portion, and the long shank portion has the lower circumferential surface abutted against the hanging portion. A stepped portion that supports the stepped portion in the shank portion is provided in the hanging portion, and the hanging portion supports the shank portion. In this way, tools having different sizes and shapes can be accommodated in one cylindrical object.
