Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring device for removing burrs from a work machined by a processing machine.

[0002]

2. Description of the Related Art Conventionally, a work processed by a processing machine, for example, a work punched by a press machine is discharged from the press machine in a state where burrs are formed during punching by the press machine. The burr formed on this work will be injured or damage other parts in that state, or the predetermined accuracy cannot be obtained during assembly, so it will be transferred to the deburring device and removed. Was there. As a conventional deburring device, for example, put the work into a belt polishing machine and polish with a polishing cloth belt, or put the work into the polishing machine and remove with a brush wheel, or the work into a barrel polishing machine. It was thrown in and removed.

[0003]

However, if the work has a high precision, the burr must be surely removed so as not to leave a burr, and the work itself cannot be scratched. Further, since the press machine processes one work piece in an extremely short time, it is necessary to deburr the work in a short time, and it is necessary to match the processing timing of the press machine. In the conventional deburring device, for example, polishing a work with a polishing cloth belt or a brush wheel requires that the finished surface of the work is not uniformly processed, and that multiple steps are required to obtain a uniform finished surface. It took a long time to process.

Further, in the deburring process using a brush wheel, since the brush wheel is mounted on a spindle whose position is fixed, the work is reciprocated or rotated to remove the burrs.
In other words, the burrs formed on the outer peripheral surface of the work cannot be removed from all the burrs because there is a portion left to be processed by down-cut from one direction of the rotating brush wheel, and the work is transferred to the brush wheel. On the other hand, it was necessary to remove all burrs by moving back and forth.

Further, when deburring a work with a barrel polishing machine, the work discharged from the press must be stored and collectively deburred, which requires a long time for transportation and rework of the work. Since it requires a set, the total time was long. Further, since a large number of works are stirred together, the works are easily damaged and the finished surface cannot be made uniform.

The present invention has been made to solve the above-mentioned problems, and can be installed in a post-process line of a press machine so that it can be synchronized with the press machine. An object of the present invention is to provide a deburring method and device that can perform deburring.

[0007]

The deburring method according to the present invention is carried out as follows in order to solve the above problems. That is, a deburring method for removing a burr of a work machined from a processing machine by a brush body, which comprises a brush body mounted on a rotatably arranged spindle, wherein the brush body is conveyed straight forward. The burr formed on the upper surface of the work is moved from the outer side of the work toward the entire periphery of the burr forming portion of the work with respect to the work to remove the burr. It is characterized by doing.

Further, the deburring apparatus according to the present invention is provided with a brush body mounted on a rotatably arranged spindle, and removes burrs of a work machined from a processing machine by the brush body. The brush body is arranged so as to rotate and revolve, and the brush body revolves with respect to the work conveyed in a straight line, whereby the brush moves from the outside of the work in the traveling direction of the work. It is characterized in that it is configured to be able to travel toward the entire circumference of the burr forming portion of the work.

Further, preferably, a planetary gear unit is arranged on the spindle, and the spindle unit is mounted at a position eccentric to a main rotating body pivotally mounted on the main shaft and arranged on the main shaft. It suffices if the planetary gear unit and the planetary gear unit are connected to the unit by a drive transmission means.

Further, it is more preferable that the main rotating body is connected to the rotation driving means supported by the machine frame by a belt.

Further, the drive transmission means may be configured to connect the sun gear part of the main shaft and the planetary gear part of the spindle with a toothed belt.

Further, it is more preferable that the work be conveyed by a conveyor supported by a machine frame.

[0013]

According to the deburring method of the present invention, the brush body mounted on the spindle and rotating rotates from the outer side of the work toward the entire periphery of the deburring portion of the work in the traveling direction of the work. Therefore, for example, deburring can be performed by up-cutting burrs formed on the entire outer peripheral surface of the work and the entire circumference around the hole by only carrying the work in one direction. Therefore, the burrs formed on the entire peripheral surface of the work by the upcut can be uniformly removed, and the deburring work can be accurately performed in a short time.

Further, in the deburring device of the present invention, the brush body is arranged so as to be able to rotate and revolve, and the brush body runs from the outside of the work toward the entire periphery of the deburring portion of the work with respect to the traveling direction of the work. Therefore, the same effect as described above can be achieved, and the revolution of the rotating brush body allows the upper surface of the workpiece to come into contact with a wide range, which enables uniform deburring, and Since deburring can be performed only by carrying the brush body and the work in one direction, a compact device can be provided.

Further, since the spindle having the planetary gear portion is mounted at the eccentric position of the main rotating body and is connected to the main shaft forming the sun gear portion through the drive transmission means, the planetary gear mechanism is realized. It can be configured and the spindle can revolve around the main axis while rotating on its own axis.
Therefore, since it is possible to rotate the spindle and revolve the spindle with a small number of parts, it is possible to provide a compact deburring device, and at the same time, it is possible to remove the burrs formed on the work by conveying the work in a straight line. It is also possible to achieve the above-described effect of removing from multiple directions and providing a uniform finished surface of the work.

Further, since the main rotating body is connected to the rotation driving means by the belt, noise generated when transmitting the rotation driving can be prevented.

Further, since the main shaft of the main rotating body is connected to the spindle by the belt, it is possible to prevent noise generated when the rotation is transmitted to the spindle.

Further, by conveying the work by the conveyor, the work can be conveyed straight to the brush body. For example, if a deburring device is installed as a post process of the press through the conveyer, the work is discharged from the press. The workpieces can be sequentially conveyed to the deburring device and synchronized with the press machine, and one press line can be made compact.

On the other hand, the spindle 13 has a shaft portion 131 supported by the carrier 12 via a bearing 18, and a shaft portion 131.
A planetary gear part 132 disposed on the upper part of the carrier 12, and by connecting the planetary gear part 132 of the spindle 13 and the sun gear part 112 of the main shaft 11 with the timing belt 19, the carrier 12 is rotated. The shaft portion 131 of the carrier 1 following the timing belt 19 that has been rotated.
Rotate in the opposite direction of 2. Therefore, a planetary gear mechanism is configured between the spindle 13 and the main shaft 11, and when the brush body 5 is attached to the lower portion of the spindle 13, the brush body 5 rotates along with the axis of the spindle 13 as the spindle 13 rotates. The rotation of the carrier 12 causes the carrier 12 to rotate (revolve) around the main shaft 11. The brush body 5 is fixed to the spindle 13 from the lower surface side of the spindle 13 by a wheel stop stud bolt 20. The planetary gear part 132 may be formed integrally with the shaft part 131, and the shaft part 13 may be formed as shown in the figure.

Reference numeral 7 is a coolant tank, and a cutting oil is ejected by arranging a nozzle toward the work W as required.

Next, the operation of the deburring device M configured as described above will be described with reference to FIGS. 1 to 12 (mainly FIGS. 5 to 12).

When the work W conveyed from the press machine is placed on the side of the work conveying belt 32 on the loading portion A side (see FIG. 5), in the belt conveyor portion 30, the motor 34 operates to rotate the drive roller 31A. Let by this,
The work transfer belt 32 sequentially moves the work W toward the brush body 5.

On the other hand, in the brush drive mechanism 10, as shown in FIG. 5, when the drive shaft 141 is rotated in one direction by the operation of the motor 14, the V pulley 15 and the V belt 16 are moved.
The V-pulley portion 121 of the carrier 12 is rotated in one direction (clockwise direction) with respect to the main shaft 11 via. With the rotation of the carrier 12, the spindle 13 having the brush body 5 mounted thereon is arranged in an eccentric position with respect to the main shaft 11 of the carrier 12, and therefore revolves around the main shaft 11 in the clockwise direction F1. At this time, the timing belt 19 rotates around the sun gear 112 on the sun gear 112 formed on the main shaft 11 that does not rotate due to the revolution of the spindle 13, so that the planetary gear 132 of the spindle 13 rotates.
Is rotated by the timing belt 19 in the opposite direction (counterclockwise) F2 to the carrier 12. Therefore, the shaft portion 131 of the spindle 132 rotates to rotate the brush body 5 counterclockwise F2 side.

Next, the operation of the brush body 5 for sequentially removing burrs from the work W conveyed by the belt conveyor section 30 will be described in detail with reference to FIGS. In addition,
Work W punched and conveyed by the press machine in the previous process
11 to 12, for example, a cross-shaped hole WH is formed in a thin disk, and a burr WB is formed on the upper surface of the outer peripheral surface of the work W and the inner peripheral surface of the cross-shaped hole WH. Are formed.

As shown in FIG. 5, the work W is carried by the work carrying belt 32 and moved to one end of the outer peripheral portion of the carrier 12. At this time, the brush body 5 is rotated in the counterclockwise direction F2 and is located, for example, at a position (left side in FIG. 5) orthogonal to the traveling direction of the work conveying belt 32, and is not in contact with the work W.

As shown in FIG. 6, when the work W further advances and the brush body 5 revolves around the main shaft 11 in the clockwise direction F1, the brush body 5 rotates and the work conveying belt 3 rotates.
Gradually move to the center of 2. Then, the brush of the brush body 5 moves from the left front position of the work W away from the left tip Wa
When it contacts with, the burr WB on the outer peripheral surface of the left front part Wa of the work W and the burr WB on the inner peripheral surface of the cross-shaped hole WH are partially scraped off by the rotation of the brush body 5 in the counterclockwise direction F2. Remove. At this time, chamfering of the corners is performed simultaneously with the removal of the burr WB.

The burr WB formed on the work W is
The brush body 5 is removed when the brush body 5 moves from a position away from the work W to the contact side toward the work W (this is referred to as upcut), and the brush body 5 separates from the side in contact with the work W to the work W. The burr WB is not completely removed when moving toward the side (this is referred to as downcut). From this, the burr WB formed on the work W must be removed by up-cut contact with all parts by the rotating brush body 5.

The left end portion W of the work W is rotated by the rotation of the brush body 5.
After removing the burr WB of A by up-cutting, the work W advances further as shown in FIG. 7, and the brush body 5 revolves clockwise relative to the main shaft 11 in the clockwise direction F1 from the front end of the work W to the front right. Move to. And the right tip W of the work W
In b, since the brush of the brush body 5 rotating in the counterclockwise direction F2 moves from a distant position on the right front side of the work W in a direction of coming into contact with the right front end portion Wb of the work W, upcut is performed. The burrs W on the right end Wb of the work W
B and a part of the burr WB on the inner peripheral surface of the cross-shaped hole WH will be removed.

Similarly, when the work W further advances, FIG.
As shown in FIG. 5, the brush body 5 is moved to the right rear of the work W, and the brush 5 is contacted from the right rear of the work W toward the right rear portion Wc of the work. Burrs WB on the right rear part Wc of the work W
And part of the burr WB on the inner peripheral surface of the cross-shaped hole WH is removed.

When the work W further advances and moves to the position where it is removed from the tip of the carrier 12, the brush body 5 revolving in the clockwise direction F1 moves to the left rear of the work W as shown in FIG. The brush of the brush body 5 which rotates in the counterclockwise direction F2 reaches the left rear portion Wd of the work W from the left rear portion of the work W and reaches the burr WB of the left rear portion Wd of the work W.
And a part of the burr WB on the inner peripheral surface of the cross-shaped hole WH is removed, and as shown in FIG. 10, at the stage where the work W is moved to a position deviated from the revolving brush body 5,
The burr WB on the entire outer peripheral surface of the work W and the entire inner peripheral surface of the cross-shaped hole WH is removed by up-cutting. When the brush body 5 contacts the upper surface of the work W, since the brushes of the brush body 5 are arranged along the circumference, the brush body 5 rotates to contact the entire upper surface of the work W. As a result, the burr W formed on the work W
B can be removed uniformly.

As described above, the brush body 5 mounted on the spindle 13 and rotating on its own axis travels from both sides of the work W toward the work W in the traveling direction of the work W. The burrs WB formed around the outer peripheral surface and the cross-shaped hole WH can be deburred by up-cutting only by conveying the work W in one direction. Therefore, it is possible to uniformly remove all the burrs WB formed on the entire peripheral surface of the work by the upcut, and it is possible to perform the work in a short time. Moreover, since the spindle 13 is mounted in the carrier 12 that rotates with respect to the main shaft 11 and can revolve around the main shaft 11 at the same time as the rotation of the carrier 12, the deburring device M has a compact structure. Can be provided.

Since the carrier 12 is connected to the motor 14 by the V belt 16 to transmit the rotation of the motor, and the main shaft 11 and the spindle 13 of the carrier 12 are connected by the timing belt 19, Noise generated during transmission of rotation can be prevented.

The brush drive mechanism 10 includes a main shaft 11
Although the sun gear unit 112 arranged in the above and the planetary gear unit 132 arranged in the spindle 13 are connected by a timing belt, the sun gear unit 112 and the planetary gear unit 132 may be directly meshed with each other. A planetary gear mechanism can be configured, and a compact deburring device that deburrs in a short time can be configured.

Furthermore, in the embodiment, the main shaft 11 is fixed to the frame 2 without rotating, but it may be connected to a motor to rotate the main shaft 11. In this case, although one motor is added, it can be preferably used when the rotation of the spindle 13 is appropriately adjusted according to the work.

When the work W has burrs WB formed not only on one side but also on both sides, two deburring devices M1 and M2 are arranged in series as shown in FIG.
The work reversing device 8 is provided on the front end side of the belt conveyor unit 30 of the first deburring device M1 to deburr the surface of the work W by the first deburring device M1, and then the work W is turned over. The second deburring device M2
Then, the same work can be performed to deburr the back surface of the work W.

Further, FIG. 14 shows a state in which the deburring device M3 is arranged in the post process of the press machine to form the press line PR. In the case of this form, when the burr generated due to the large punched-out portion of the work W cannot be removed by the brush body, the belt polishing device M4 is installed on the depressing device P side of the deburring device M3 to perform rough removal. After that, the brush body 5 of the deburring device M4 is used for finishing.
After the work W is punched by the press machine P, it is conveyed to the conveyor section 30 of the deburring device M3 by a discharge device (not shown) installed on the press machine P side. When the burr formed on the work W is formed on the lower surface side of the work W, the work reversing device 8 shown in FIG. 13 is arranged to reverse the work W, and then the work W is placed on the conveyor unit 30. You can do it.

As described above, by arranging the belt conveyor section 30 in the deburring device M and conveying the work W toward the brush body 5 side by the belt conveyor section 30,
The work W can be conveyed straight to the brush body 5,
For example, if the deburring device M is installed as a post-process of the press machine, the works W discharged from the pressing machine can be sequentially conveyed to the deburring device M and synchronized with the press machine.
A press line can be constructed.
