The deburring machine comprises a transposition mechanism, clamps arranged on the transposition mechanism, and a gear shaving mechanism arranged corresponding to one of the clamps when the transposition is stopped. In one embodiment, as shown in fig. 1, a shaving mechanism of a deburring machine includes a shaving base 40, a shaving driving device 30 disposed on the shaving base 40, the shaving driving device 30 includes an output shaft capable of reciprocating up and down, the output shaft is connected with a shaving pressing plate 33, and the shaving pressing plate 33 is correspondingly disposed above a workpiece 50.

The gear shaving driving device 30 can be a gear shaving air cylinder 31, the cylinder barrel of the gear shaving air cylinder 31 is connected with the gear shaving base 40, and the output shaft is the cylinder rod of the gear shaving air cylinder 31. The shaving pressure plate 33 is mounted on a cylinder rod of the air cylinder.

The adoption of the air cylinder as the gear shaving driving device 30 can ensure that the gear shaving pressing plate 33 can reciprocate up and down quickly and accurately. Of course, other devices may be used as the shaving drive device 30, for example, a hydraulic cylinder connected to a hydraulic pump may be used.

The gear shaving mechanism further comprises an auxiliary positioning device 20 and a cutter clamping device 10 which are independently arranged, wherein the independent arrangement means that the auxiliary positioning device 20 and the two sets of systems of the tool clamping device are relatively independent, and a driving part and an executing part of the auxiliary positioning device are relatively independent. The tool holding device 10 of the present invention includes a shaving cutter 12 and a feed cylinder 11 for driving the shaving cutter 12 to reciprocate relative to a workpiece 50. Wherein the profile of the shaver 12 matches the profile of the tooth of the workpiece 50 with which it is engaged.

The auxiliary positioning device 20 includes an abutment plate 22 and a positioning holding cylinder 21 that drives the abutment plate 22 to reciprocate relative to the workpiece 50, the abutment plate 22 being disposed opposite to the shaver 12. The gear shaving cutter 12 and the abutting plate 22 are respectively driven by the feed telescopic cylinder 11 and the positioning clamping cylinder 21 to engage and clamp the workpiece 50 or loosen the workpiece 50 from the gear side of the workpiece 50 and the opposite side of the gear side.

It should be noted that the engagement clamping means that the tool is engaged with the tooth side of the workpiece 50, and the abutment plate 22 and the tool are both engaged to clamp the workpiece 50.

The abutment plate 22 and the shaver 12 may be substantially in line, which facilitates reliable clamping of the workpiece 50 and avoids rotation of the workpiece 50 by torque.

The technical effect is described by taking the deburring machine as a rotating disc type deburring machine as an example, and of course, it should be understood by those skilled in the art that the technical solution is not limited to be applied to the rotating disc type deburring machine, and the application to other types of deburring machines is also within the protection scope of the present disclosure.

After the deburring machine finishes a grinding process, a rotary table of the deburring machine drives the workpiece 50 to rotate to a corresponding position of a gear shaving mechanism, the cutter clamping device 10 and the auxiliary positioning device 20 are controlled to be in action fit with each other to clamp the workpiece 50, the upper surface of the gear shaving cutter 12 is slightly lower than the upper surface of the workpiece 50, and therefore when the gear shaving driving device 30 is controlled to drive the gear shaving pressing plate 33 to move downwards, the workpiece 50 is pushed to move downwards relative to the gear shaving cutter 12, and the gear shaving cutter 12 slides up and down in a tooth socket of a gear tooth to slide and drop scattered burrs adhered to the upper portion in the tooth socket of the gear tooth downwards relative to the gear tooth. Then, the shaving drive device 30 is controlled to drive the shaving pressure plate 33 to move upward, so that the remaining very small amount of scattered burrs slide and fall off relative to the gear teeth. Then, the tool holding device 10 and the auxiliary positioning device 20 are controlled to release the workpiece 50, and the shaving operation is completed. Because the workpiece 50 is clamped on the universal floating fixture, the workpiece 50 can be automatically reset upwards under the action of the spring, and the turntable continues to rotate, so that the workpiece 50 is driven to continue to rotate.

The utility model discloses a mode that auxiliary positioning device 20 and cutter clamping device 10 cooperation pressed from both sides tight work piece 50 is shaving in the realization machinery automation, improves under the prerequisite of shaving the efficiency of tooth technology, and the executive component etc. of two devices is relatively independent, and work mutual noninterference, and cost of maintenance is lower, can improve the flexibility that the mechanism set up simultaneously.

In the above embodiment, the shaving base 40 has a first slide rail and a second slide rail which are oppositely arranged, the tool holding device 10 and the auxiliary positioning device 20 are respectively provided with the tool guide rail 14 and the adjustment guide rail 24, and the tool guide rail 14 and the adjustment guide rail 24 are respectively installed in cooperation with the first slide rail and the second slide rail so as to position the shaving cutter 12 and the abutting plate 22 in the same longitudinal direction.

That is, in order to keep the shaving cutter 12 and the abutment plate 22 at the same longitudinal position, the shaving base 40 and the tool holding device 10, and the shaving base 40 and the auxiliary positioning device 20 are cooperatively mounted or operated by means of a slide rail and guide rail type, so as to ensure that the shaving cutter 12 and the abutment plate 22 are at the same longitudinal position after the tool holding device 10 and the auxiliary positioning device 20 are mounted. I.e. the direction of the force exerted by the shaver 12 on the workpiece 50 is substantially collinear with the direction of the force exerted by the abutment plate 22 on the workpiece 50.

It should be noted that the longitudinal direction herein refers to the direction of the force exerted on the workpiece 50 by the shaver 12 and the abutment plate 22.

Specifically, the tool holding device 10 in the above embodiment further includes a tool mounting base 13, the shaving cutter 12 and the tool guide 14 are disposed on the tool mounting base 13, and the movable end of the feed telescopic cylinder 11 is connected to the tool mounting base 13.

When the feed telescopic cylinder 11 drives the cutter mounting seat 13 to act, the cutter mounting seat 13 is matched with the first slide rail to slide through a cutter guide rail 14 arranged on the cutter mounting seat.

Due to the reasons of product processing error or installation error, the engaging force between the gear shaving cutter 12 and the workpiece 50 after being installed is too large or too small, and when the gear shaving cutter 12 is worn after long-term use, a certain gap is generated between the gear shaving cutter 12 and the workpiece 50, namely, the gear teeth of the gear shaving cutter 12 and the workpiece 50 cannot be tightly engaged, so that the burrs cannot be completely removed, or the efficiency of removing the burrs is reduced. Therefore, the following arrangement is also made herein.

In a specific scheme, the gear shaving mechanism further comprises a cutter positioning device 15, the gear shaving cutter 12 is installed in the cutter positioning device 15, and the cutter positioning device 15 comprises a cutter feeding rod 16 for adjusting the front and back positions of the gear shaving cutter 12; a tool positioning device 15 is attached to the front end of the tool mount 13.

Through the arrangement, after the components are assembled, the position between the front and the back of the gear shaving cutter 12 can be adjusted through the cutter feeding rod 16, so that the meshing force between the gear shaving cutter 12 and the gear teeth of the workpiece 50 is proper, and the reliable deburring is realized. In addition, when the shaver 12 is worn out after long-term use, the feed bar 16 can be adjusted to move the shaver 12 a certain distance relative to the workpiece 50 side so that the shaver 12 is again brought into proper engagement with the teeth of the workpiece 50.

The variety of workpieces 50 machined by the deburring machine may not be singular, i.e., the deburring machine may machine products of different gear tooth shapes, each product corresponding to one model of the shaver 12. In order to minimize the problem of low machining efficiency caused by replacement of the shaving cutter 12, the following modifications are made to the shaving mechanism.

The cutter positioning device in each of the above embodiments includes the mounting clip body 151 having the mounting recess 151a, the opening of the mounting recess 151a being forward, the rear end portion of the shaver 12 being mounted inside the mounting recess 151a, specifically, the rear end portion of the shaver 12 may be fixed inside the mounting recess 151a by a bolt or the like, and the serrated head of the shaver 12 protruding outside the mounting recess 151 a. A side wall 1511 of the mounting groove 151a is detachably connected with the mounting clamp body 151, the side wall 1511 can be fixed with the mounting clamp body 151 through bolts, and the side wall 1511 can be tightly pressed against the bolts to be used for abutting and positioning the side face of the gear shaver 12. The bottom wall of the mounting groove 151a has a threaded through hole, and the feed bar 16 is a feed bolt longitudinally disposed in the threaded through hole.

With this structure, the positions of both sides of the shaver 12 can be restricted by tightening the bolts, the groove bottom wall of the mounting groove 151a can restrict the position of the rear side of the shaver 12, and the front side of the shaver 12 is engaged and clamped with the workpiece 50, whereby it can be seen that the cutter positioning device can simply and conveniently fix the shaver 12. When the tooth-shaped cutter head of the gear shaving cutter 12 is worn after working for a period of time, fine adjustment of the gear shaving cutter 12 in the front-back direction can be realized only by operating the cutter feeding rod 16. In addition, when the gear shaving cutter 12 needs to be replaced, only the side wall needs to be detached from the mounting clamp body 151, and the existing gear shaving cutter 12 can be replaced, so that the gear shaving cutter has the characteristics of convenience and quickness in tool changing.

In one embodiment, in order to make the surface mount clip 151 collide with a component on the floating mechanism when the surface mount clip 151 is extended, a lower portion of a front end surface of the mount clip 151 is provided with a first recess and a second recess from top to bottom, and the second recess is recessed inward by a size larger than that of the first recess.

In the above embodiments, the auxiliary positioning device 20 further includes an adjusting mounting plate and a clamping limiting member, the fixed end of the positioning clamping cylinder 21 is fixed to the adjusting mounting plate 23, and the cylinder of the positioning clamping cylinder 21 can be fixed to the adjusting mounting plate 23 through the connecting plate 28. The shaving base 40 is provided with a mounting vertical plate opposite to the adjusting mounting plate 23, and the opposite surfaces of the mounting vertical plate and the adjusting mounting plate 23 are respectively provided with a second sliding rail and an adjusting guide rail 24; the adjusting and mounting plate is longitudinally positioned with the shaving base 40 through the clamping limiting part and then fixed with the mounting vertical plate through the fixing part. The fixing member may be a bolt.

The structure in which the risers are mounted is not shown, but does not hinder the understanding and implementation of the solution by the skilled person.

The position of the positioning clamping cylinder 21 can thus be determined by the longitudinally cooperating second slide rail and adjustment rail 24.

In one embodiment, the clamping position-limiting member includes a first bolt 25 and a second bolt 26 which are longitudinally opposite to each other, and both of the first bolt and the second bolt are in threaded connection with the shaving base 40, as shown in the figure, a connecting plate 27 is provided on the shaving base 40, two vertical plates extending outward are provided on the connecting plate 27, threaded through holes extending longitudinally are provided on the vertical plates, and the first bolt 25 and the second bolt 26 are respectively installed in the threaded through holes. The adjusting and mounting plate 23 is at least partially located between the first bolt 25 and the second bolt 26, that is, the adjusting and mounting plate 23 may be partially or entirely located between the first bolt 25 and the second bolt 26, but it is preferable that the adjusting and mounting plate is partially located between the first bolt 25 and the second bolt 26 for convenience of installation. In one embodiment, the upper portion of the adjustment mounting plate 23 has an upwardly extending boss located between the first bolt 25 and the second bolt 26.

The utility model discloses in through the relative extension length of adjusting first bolt 25 and second bolt 26, can adjust the longitudinal front and back position of adjustment mounting panel. For example, when the first bolt 25 is extended to the right and the second bolt 26 is retracted to the left, the position of the adjustment mounting plate can be moved along the second slide rail for fine adjustment to the right, and when the adjustment mounting plate is adjusted to the proper position, the clamping position is lowered by using the first bolt 25 and the second bolt 26, and then the adjustment mounting plate is fixed to the shaving base 40 by using a fixing member such as a bolt.

In a further aspect, as shown in fig. 1, the shaving mechanism further includes a lower limit position assembly 35 that limits a lower limit position of the shaving pressing plate 33, where the lower limit position assembly 35 includes a first limit block mounted on the mounting vertical plate and a second limit block connected to a cylinder rod of the shaving cylinder 31, and when the shaving cylinder 31 extends to a predetermined position, the second limit block abuts against the first limit block.

In this way, the lower limit component 35 can accurately limit the maximum displacement of the shaving pressure plate 33, so as to ensure the accuracy of the shaving process.

Specifically, the shaving pressing plate 33 may be provided with a protrusion extending laterally, and the mounting upright plate is also provided with a boss opposite to the protrusion, and the protrusion and the boss are abutted and limited.

In addition, the gear shaving mechanism may further include a gear shaving buffer 34 for preventing the gear shaving pressure plate 33 from moving downward and impacting the first stopper. In particular, the shaving cushion 34 may be an oil cushion 34. The gear shaving cushioning member 34 and the second stopper are respectively located on the right and left sides of the gear shaving pressing plate 33.

Thus, when the shaver 12 moves downward, the oil cushion 34 can slow down the descending speed when the shaver 12 is fast to the lower limit position, so as to avoid the larger noise and vibration generated during descending of the shaver 12 and avoid the damage of the shaver 12 due to the collision with the lower limit position.

Since the above-mentioned shaving mechanism has the technical effects as described above, a deburring machine using the shaving mechanism should also have the same technical effects, and will not be described in detail herein.
