Description

Compound function side milling cutter

The invention relates to milling machines, and in particular to side blades for use in providing side milling cutters.

The side milling cutter seat of the conventional method mainly comprises a seat body mounted on a working machine, a set of transmission systems disposed on the seat body, and a set on the seat body and the transmission The system is powered by a connecting rod. The transmission system includes at least one input shaft for connecting the output power of the working machine and transmitting the output power to the arbor. The arbor is used to mount a side milling cutter and transmit power to the side milling cutter to cut a workpiece.

The angle between the shank of the side milling cutter seat and the input shaft is fixed, so that the workpiece can only be cut at a fixed angle, and the processing needs thereof, such as hobbing processing, cannot be satisfied.

On the other hand, before the side cutter is installed on the cutter bar of one side milling cutter holder, the cutter bar must be removed from the seat. The transmission system of the conventional side milling cutter base includes an output shaft, and the output shaft coaxially has a square socket. The end of the shank of the conventional side milling cutter holder has a quadrangular column-shaped insertion portion for inserting into the above-mentioned insertion groove to complete the transmission connection of the arbor to the transmission system. The other end of the shank is passed through a bearing fixedly disposed on the base. In addition, a long screw passes through the outer end surface of the shank and a through hole extending axially through the shank, and the end surface of the shank is located in the insertion groove, and is locked at one of the plugs. The shank is fixed to the transmission system in the screw hole in the slot.

Since the bearing for carrying the arbor on the side milling cutter seat is fixed on the seat body, the way of removing the arbor is to loosen the long screw from the arbor and then insert the arbor. Extracted from the groove and bearing. This approach has the following disadvantages:

1. In the process of separating or combining the shank and the bearing, the bearing is easily damaged by the collision of the arbor, resulting in errors in the process of machining the workpiece due to the smooth rotation of the arbor.

Second, the cutting iron scraps and other impurities contaminated on the arbor are easily brought into the arbor and the bearing; at the same time, in order to facilitate the extraction of the arbor from the arbor, the bearing can not have a good seal, and also causes impurities such as cutting iron filings. Balls that easily enter the bearing form components, causing wear of the bearing during rotation.

Third, due to the need to extract the arbor from the bearing, the maximum outer diameter of the shank must be limited by the inner diameter of the bearing, so that the arbor can not be equipped with a larger size side milling cutter.

In view of this, the main object of the present invention is to provide a composite function side milling cutter holder, wherein an angle between the input shaft and the cutter bar can be adjusted to be suitable for a machining method such as a hobbing machine.

Another object of the present invention is to provide a composite function side milling cutter holder, which is a modular design of a cutter rod and a bearing for carrying the cutter rod, and can be integrally detached from the seat body thereof. Body to reduce the chance of bearing damage.

The adjusting ring 38 threaded section 384 is coupled to the threaded section 3412 at the outer end of the output shaft 34. When the bolt 383 is released, the adjusting ring 38 can be rotated to adjust the position of the adjusting ring 38 on the output shaft 34; When the bolt 382 is locked, the position of the adjusting ring 38 on the output shaft can be fixed. By the arrangement of the adjusting ring 38 and the use of the spacer, the position of the side milling cutter mounted on the shank 41 can be adjusted.

Hereinafter, how the composite side milling cutter holder 1 achieves the object and function of the foregoing invention will be explained.

First, referring to FIG. 5, FIG. 6, and FIG. 8, since the angle between the main body 11 and the sub-body 12 can be adjusted, that is, the adjusting bolts 23 are loosened, so that the pressing is tight. The block 21 is loosened from the groove wall of the accommodating groove 1212, so that the joint surface 1211 of the base plate 121 can be loosened from the joint surface 111 of the main seat body 11; at this time, the sub-seat body 12 is rotated to make the sub-seat body 12 along the pressing blocks 21 and the rooms The angle between the sub-body 12 and the main seat 11 can be adjusted by rotating the circular orbits formed by the spacers 22. Moreover, by tightening the adjusting bolts 23, the pressing blocks 21 can be pressed against the groove wall of the accommodating groove 1212, and the engaging surface 1211 of the base plate 121 is pressed tightly against the main seat body 11. On the joint surface 111, the locking engagement of the sub-body 12 with the main seat body 11 is achieved to fix the angle between the sub-body 12 and the main seat body 11.

Since the input shaft 31 of the transmission system is mounted on the main body 11, and the shank 41 of the shank module 40 is mounted on the sub-seat 12, the main body 11 and the sub-seat The angle between the bodies 12 can be adjusted and changed, so that the angle between the input shaft 31 and the arbor 41 can be adjusted and changed. In this way, the composite side milling cutter holder 1 can be applied not only to the general side milling process, but also to other types of machining, for example, replacing the hobbing cutter on the cutter bar 41 and appropriately adjusting the cutter bar 41. After the angle with the input shaft 31, hobbing is performed.

Secondly, referring to FIG. 6 and FIG. 9 , the composite function side milling cutter holder 1 adopts a design that the cutter module 40 is integrally assembled and disassembled, that is, the cutter bar 41 , the bearing 43 , and the bearing seat 42 . And the dust cover 44, the O-ring 45 and the size V-shaped oil seals 46, 47 are pre-assembled to form a module, and are assembled to the sub-body 12 or the sub-body 12 from the entire mold. Remove it on the top.

The design is such that the shank 41 and the bearing 43 do not need to be repeatedly coupled or detached, so that the bearing 43 can be prevented from being collided by the arbor 41, and the chance of damage can be reduced.

Moreover, since the arbor 41 and the bearing 43 do not need to be repeatedly coupled or detached, It is avoided that impurities such as cutting iron chips contaminated by the machining on the shank 41 are brought between the shank 41 and the bearing 43. At the same time, since the arbor 41 and the bearing 43 do not need to be repeatedly combined or detached, the entire arbor module 40 can have a good dustproof design. In the present example, the dust cover 44 and the bearing housing are The O-ring and the V-shaped oil seal are respectively disposed between the 42 and the dustproof cover 44 and the penetration portion 416 of the shank 41, and are disposed between the second protrusion 415 of the shank 41 and the bearing housing 42. There is a V-type oil seal. With such a good dustproof design, it is possible to greatly reduce the chance that impurities such as cutting iron chips can easily enter the constituent members of the ball of the bearing 43, and the service life of the bearing can be prolonged.

Moreover, since the shank 41 and the bearing 43 need not be repeatedly coupled or detached, the overall outer diameter of the shank 41 need not be limited by the inner diameter of the bearing 43, as in the embodiment, the arbor The outer diameter of the knife portion 413 of the 41 is larger than the outer diameter of the penetration portion 416, and is available for a larger size side cutter.

The above description is only for the preferred embodiments of the present invention, and the equivalent structures and manufacturing methods of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
