Description

Technical Field

[0001] The invention relates to the technical field of gear processing, in particular to an automatic deburring machine. Background Art

[0002] Gears are a common mechanical transmission part that plays an important role in the mechanical field. With the rapid development of the gear industry, the industry scale continues to expand, and the performance requirements for gears are getting higher and higher. During the machining process of gears, due to various reasons such as cutting, casting, and die forging, thorns or flash will form on the gears, which are called burrs.

[0003] The presence of burrs will have a negative impact on the performance and service life of gears. Gear deburring is to improve product performance, reduce friction and noise, and extend service life. Therefore, it is very necessary to deburr the gears. In the deburring process, burr removal equipment is usually used.

[0004] The existing gear deburring machine has low efficiency in conveying workpieces during deburring processing, and the workpiece is prone to deviation during conveying. In addition, the brush working state of the existing gear deburring machine is difficult to adjust, and the grinding quality is poor. In order to solve the above technical problems, many related patents have been proposed in the prior art, including a Chinese patent with application number 201921579010.X, authorization announcement number CN210731958U, and the name of a gear deburring machine. The above patent discloses a gear deburring machine, including a frame, a conveyor and a vacuum cleaner pipe, the upper side of the frame is connected to the conveyor by bolts, the conveyor is connected to a permanent magnetic suction cup by bolts, the conveyor is connected to an iron pin funnel by bolts on both sides, and the iron pin funnel is connected to a cutting groove by a slot below. In the above patent, by setting a permanent magnetic suction cup, a conveyor, an iron pin funnel, a cutting groove and a vacuum cleaner pipe, the equipment can quickly and stably convey the workpiece, and the iron pins generated by deburring can be conveniently collected, which can ensure the cleanliness of the workbench.

[0005] Another example is the application number 202223392758.3, the authorization announcement number CN218800287U, and the patent name is a gear deburring machine. The above patent discloses a gear deburring machine, including a fixed seat, the top of the fixed seat is fixedly connected to a support seat, the top of the support seat is fixedly connected to a placement rack, the side of the placement rack is fixedly connected to a side rod rack, the interior of the placement rack is fixedly connected to an internal rod, the surface of the internal rod is movably connected to a fixed gear, the top of the side rod rack is movably connected to a replacement rack, the top of the replacement rack is installed with a fixed motor, one end of the rotating rack is fixedly connected to a grinding plate, and the grinding plate is located above the fixed gear. In the above patent, the placement rack, the rotating rod, the fixed motor and the grinding plate are used in coordination to avoid the inability to quickly deburr the machine during use, thereby delaying the normal use of the staff.

[0006] In the prior art, such as the above-mentioned patent, the gear is mounted on a predetermined workbench, and as the workbench rotates, the gear is intermittently in contact with the burr removal device, which can improve the quality of gear deburring to a certain extent. However, after the gear is mounted on the workbench, as the workbench rotates, the gear is driven to contact the burr removal device for burr removal. However, this method can only achieve the burr removal effect on the side of the gear that contacts the burr removal device, and when other parts of the gear have not yet contacted the burr removal device, they will be moved to the side away from the burr removal device by the rotating workbench. Therefore, the angle of the gear needs to be constantly adjusted to meet the needs of gear deburring, which has certain shortcomings. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-16 The present invention provides a technical solution: an automatic deburring machine, which includes a frame 1 and a polishing mechanism 3 installed on one side of the frame 1. Optionally, an anti-slip support is arranged at the bottom of the frame 1 to improve the stability of the entire equipment during operation, thereby improving the stability during burr removal operations. The polishing mechanism 3 includes a support frame fixedly connected to the frame 1, a mounting plate slidably connected to the support frame, a driving motor is arranged on the mounting plate, and a polishing wheel is arranged on the output shaft of the driving motor. When working, the driving motor is started to drive the polishing wheel to rotate to perform deburring operations. Preferably, a servo cylinder for driving the mounting plate to slide is arranged on the support frame, so that the state of the polishing wheel can be adjusted, thereby further improving the scope of application of the deburring machine and meeting the processing needs of more workpieces.

[0040] A carrier 2 is rotatably connected to the frame 1, wherein a damping swivel is provided on the side surface of the carrier 2, and a damping rotation groove is provided inside the frame 1, wherein the damping swivel is rotatably connected in the damping rotation groove, which can improve the stability of the carrier 2 during rotation, and when rotation is not required, the carrier 2 will be stably installed on the frame 1. Multiple groups of carrier cylinders 4 are rotatably connected to the carrier 2, wherein a carrier plate 4.1 is fixedly connected to the carrier cylinder 4, and a gear workpiece 8 is installed on each carrier cylinder 4, and the gear workpiece 8 will be placed on the carrier plate 4.1 when installed, so as to facilitate the subsequent processing needs of the gear workpiece 8. Preferably, the number of the carrier cylinders 4 can be four, five, six, etc., which can be designed according to the work needs, and the structure and working principle of the carrier cylinder 4 are consistent, which will not be described one by one here, and one of them will be described in detail below. A driving rod 7 for driving the carrier 2 to rotate is provided inside the frame 1, and the driving rod 7 is intermittently connected to the carrier 2 through the fastening unit 11. In order to better drive the bearing platform 2 to rotate, a connecting block 10 is fixedly connected to the bottom of the bearing platform 2. Specifically, the fastening unit 11 includes a plurality of fastening blocks 11.1 fixedly connected to the driving rod 7. A plurality of fastening grooves 11.2 matching the fastening blocks 11.1 are provided on the connecting block 10, wherein the fastening blocks 11.1 are engaged with the fastening grooves 11.2. When the fastening blocks 11.1 are engaged in the fastening grooves 11.2, the driving rod 7 rotates at this moment, which drives the bearing platform 2 to rotate through the connecting block 10. On the contrary, when the fastening blocks 11.1 are disengaged from the fastening grooves 11.2, the driving rod 7 cannot drive the bearing platform 2 to rotate.

[0041] A servo motor 6 for driving the driving rod 7 to rotate is provided inside the frame 1 to provide power for the rotation of the carrier 2. Specifically, a reducer is provided on the output end of the servo motor 6 to meet the working needs. A linkage mechanism 15 for driving multiple groups of carrier cylinders 4 to rotate is also provided on the frame 1, and the linkage mechanism 15 is connected to the driving rod 7 through a switching mechanism 12. Therefore, the servo motor 6 can drive the carrier 2 to rotate. After the carrier cylinder 4 with the gear workpiece 8 installed is rotated to a predetermined position, the switching mechanism 12 is used to release the power of the carrier 2 during the stroke in which the servo motor 6 is connected to the linkage mechanism 15. At this moment, only the carrier cylinder 4 drives the gear workpiece 8 to rotate, and the carrier 2 does not rotate. At this time, the polishing mechanism 3 performs a complete polishing operation on the side surface of the gear workpiece 8, and there is no need to adjust the angle of the gear workpiece 8 later, and the use effect is excellent.

[0042] During use, the following two stations will be generated:

[0043] At the first station, the servo motor 6 drives the carrier 2 to rotate through the driving rod 7, and drives the gear workpiece 8 to the polishing station. That is, in the original process, the fastening block 11.1 will be clamped in the fastening groove 11.2. At this time, the servo motor 6 drives the driving rod 7 to rotate through the output shaft. The driving rod 7 rotates and drives the carrier 2 to rotate through the connection block 10 through the cooperation between the fastening block 11.1 and the fastening groove 11.2. When the carrier 2 rotates, it drives the multiple groups of gear workpieces 8 on the carrier 2 to rotate together on the frame 1, and drives the gear workpiece 8 to be processed to the polishing station, and then uses the polishing mechanism 3 to perform deburring.

[0044] In the second station, the switching mechanism 12 drives the driving rod 7 to slide away from the side of the carrier 2, which will connect the driving rod 7 with the linkage mechanism 15. At this time, the driving rod 7 drives the gear workpiece 8 to rotate through the linkage mechanism 15 and the carrier tube 4, and the polishing mechanism 3 performs a deburring operation on the gear workpiece 8. Specifically, in the stroke in which the servo motor 6 drives the driving rod 7 to rotate continuously, the switching mechanism 12 between the driving rod 7 and the frame 1 drives the fastening block 11.1 on the driving rod 7 to gradually slide to the side away from the fastening groove 11.2 until it slides out completely. In the stroke in which the switching mechanism 12 drives the driving rod 7 to disengage from the carrier 2, the driving rod 7 is connected with the linkage mechanism 15. At this time, when the servo motor 6 drives the driving rod 7 to rotate, it drives multiple groups of carrier tubes 4 to rotate synchronously through the linkage mechanism 15. Since the fastening block 11.1 on the driving rod 7 slides out from the inside of the fastening groove 11.2, the carrier 2 is in a stationary state during the process in which the driving rod 7 drives the linkage mechanism 15 to rotate. That is, at this time, only the gear workpiece 8 rotates, and the supporting platform 2 does not rotate. At this moment, the polishing mechanism 3 performs a complete polishing operation on the side surfaces of the gear workpiece 8. During this operation, there is no need to adjust the angle of the gear workpiece 8 subsequently. The use effect is excellent, which can greatly improve the working efficiency of the entire equipment and is suitable for wide promotion and use.

[0045] In the embodiment provided by the present invention, a gear fastening mechanism is further provided between the bearing cylinder 4 and the gear workpiece 8. When the linkage mechanism 15 drives the bearing cylinder 4 to rotate, the gear workpiece 8 is fixed by the gear fastening mechanism to improve the stability of the gear workpiece 8 during deburring. A gear fastening mechanism is provided between each bearing cylinder 4 and the corresponding gear workpiece 8, and the gear fastening mechanism has the same structure and working principle. Only one of them is described here. By providing the gear fastening mechanism, the gear workpiece 8 will be fixed by the gear fastening mechanism when the bearing cylinder 4 rotates. On the one hand, the gear workpiece 8 can be driven to rotate during the rotation of the bearing cylinder 4, thereby improving the stability of the gear workpiece 8 during rotation. On the other hand, after the gear fastening mechanism fixes the gear workpiece 8, the shaking of the gear workpiece 8 during the polishing operation of the polishing mechanism 3 is reduced, which can further improve the stability of the gear workpiece 8 during the polishing operation, and the use effect is better.

[0046] In the embodiment provided by the present invention, a rotating frame 5 is rotatably connected inside the frame 1, and the rotating frame 5 is fixedly connected to the bearing platform 2. When the bearing platform 2 rotates, the rotating frame 5 is driven to rotate together. A power rod 9 is rotatably connected to the rotating frame 5, and a fixing ring 16 is installed on the power rod 9. Specifically, the fixing ring 16 is rotatably connected to the power rod 9. The linkage mechanism 15 is arranged between the fixing ring 16 and the multiple groups of bearing cylinders 4, and the servo motor 6 is coaxially connected with the power rod 9, and the servo motor 6 is used to drive the power rod 9 to rotate. The driving rod 7 is slidably connected to the power rod 9. Specifically, a vertical groove is provided inside the driving rod 7, wherein the power rod 9 is slidably connected to the driving rod 7 through the vertical groove, and a positioning spring 20 is arranged between the driving rod 7 and the vertical groove, which can improve the stability between the driving rod 7 and the power rod 9. A limiting member is arranged between the power rod 9 and the driving rod 7 to ensure that the driving rod 7 and the power rod 9 can only slide, and the two cannot rotate relative to each other, so as to meet the needs of subsequent processing.

[0047] In the embodiment provided by the present invention, the switching mechanism 12 includes a switching rod 12.1 fixedly connected to the driving rod 7, and a plurality of groups of first station slots 12.2 and a plurality of groups of second station slots 12.3 that are connected to each other are provided on the frame 1, and the switching rod 12.1 is intermittently arranged in the first station slots 12.2 and the second station slots 12.3. Specifically, there are multiple groups of first work station slots 12.2 and second work station slots 12.3, and the multiple groups of first work station slots 12.2 are respectively located above the multiple groups of second work station slots 12.3, and the first work station slots 12.2 and the second work station slots 12.3 are intermittently arranged, that is, one second work station slot 12.3 is arranged between two first work station slots 12.2, one first work station slot 12.2 is arranged between two second work station slots 12.3, and both sides of the first work station slot 12.2 are provided with inclined track slots that are conductive with the second work station slots 12.3. Therefore, the movement trajectory of the switching rod 12.1 is: first work station slot 12.2-inclined track slot-second work station slot 12.3-inclined track slot-first work station slot 12.2... During the movement of the switching rod 12.1, the driving rod 7 will be driven to produce a corresponding movement trajectory. More specifically, the lengths of the first station slot 12.2 and the second station slot 12.3 can be designed according to work needs (the number of gear workpieces 8 to be installed), so that after the foot support platform 2 drives the gear workpiece 8 to the polishing station, the switching rod 12.1 will move from the first station slot 12.2 to the second station slot 12.3; the length of the second station slot 12.3 can meet the rotation of the gear workpiece 8 by no less than 360°, and the gear workpiece 8 can be fully polished. More specifically, the fastening block 11.1 on the driving rod 7 and the fastening slot 11.2 at the bottom of the connecting block 10 are also compatible with the lengths of the first station slot 12.2 and the second station slot 12.3. When the switching rod 12.1 moves from the second station slot 12.3 to the inside of the first station slot 12.2, it can be realized that the fastening block 11.1 must be snapped into the corresponding fastening slot 11.2. This implementation method is a prior art, and its principle will not be repeated here.

[0048] More specifically, during operation, when the switch rod 12.1 is located inside the first station slot 12.2, the drive rod 7 is connected to the carrier 2 at this moment. When the servo motor 6 is started, the carrier 2 is driven to rotate by the drive rod 7, and the gear on the carrier 2 can be rotated to a predetermined polishing position. When the switch rod 12.1 is located inside the second station slot 12.3, the drive rod 7 is connected to the fixed ring 16 through the connecting unit, and the multiple groups of carrier cylinders 4 are driven to rotate synchronously through the linkage mechanism 15. That is, as the drive rod 7 continues to rotate, the switch rod 12.1 at this moment will enter the second station slot 12.3 through the inclined track groove, and the drive rod 7 will be separated from the carrier 2 at this moment. At this time, the rotation of the drive rod 7 will not drive the carrier 2 to rotate. When the driving rod 7 rotates, the fixing ring 16 is driven to rotate through the connecting unit, so that the linkage mechanism 15 can be driven to move through the fixing ring 16. At this moment, when the servo motor 6 drives the driving rod 7 to rotate, the linkage mechanism 15 drives the multiple groups of bearing tubes 4 to rotate synchronously. At this moment, only the gear workpiece 8 rotates, and the bearing platform 2 does not rotate. At this moment, the polishing mechanism 3 performs a complete polishing operation on the side of the gear workpiece 8, and there is no need to adjust the angle of the gear workpiece 8 later. The use effect is excellent, which can greatly improve the working efficiency of the entire deburring equipment and is suitable for wide promotion and use. Preferably, no matter whether the switching rod 12.1 moves in the first station slot 12.2 or in the second station slot 12.3, the positioning spring 20 located between the driving rod 7 and the power rod 9 will produce a certain deformation, that is, generate elastic force, which can more conveniently drive the switching rod 12.1 to move from the second station slot 12.3 to the first station slot 12.2 side, or the first station slot 12.2 to the second station slot 12.3, and the use effect is better.

[0049] In the embodiment provided by the present invention, specifically, the linkage mechanism 15 includes a rotating rod 14 rotatably connected to the rotating frame 5, and the rotating rod 14 and the multiple groups of bearing cylinders 4 are connected through a transmission unit 13. The transmission unit 13 includes a sprocket 13.2 installed on the rotating rod 14 and the multiple groups of bearing cylinders 4, and the multiple groups of sprockets 13.2 are connected through a chain 13.1. At this moment, when the rotating rod 14 rotates, the sprocket 13.2 of the rotating rod 14 will be driven to rotate, thereby driving the chain 13.1 to rotate, and the multiple groups of sprockets 13.2 are driven to rotate synchronously through the chain 13.1 to meet the working needs. The linkage mechanism 15 also includes a shaft 15.3 rotatably connected to the rotating frame 5, and the shaft 15.3 is connected to the rotating rod 14 through a speed change gear set. Specifically, the speed gear set includes a first speed gear 15.1 installed on the rotating rod 14, and a second speed gear 15.2 is also installed on the shaft 15.3. The first speed gear 15.1 is meshed with the second speed gear 15.2. The first speed gear 15.1 and the second speed gear 15.2 have different gears. By utilizing the relationship of the transmission ratio, the angle of rotation of the second speed gear 15.2 drives the first speed gear 15.1 to rotate at least 360°, so that the gear workpiece 8 can be polished in all aspects. Specifically, the transmission ratio is the existing technology, and its principle is not repeated here. At the same time, a first synchronous wheel 15.4 is installed on the shaft 15.3, and a second synchronous wheel 15.5 is rotatably connected to the rotating frame 5. The first synchronous wheel 15.4 and the second synchronous wheel 15.5 are connected by a synchronous belt 15.6, and an intermittent clamping member 17 is provided between the second synchronous wheel 15.5 and the fixed ring 16. Therefore, when the supporting platform 2 rotates, the rotating frame 5 will drive the shaft 15.3 to rotate. At this moment, when the shaft 15.3 rotates, it will drive the first synchronous wheel 15.4 to rotate, and the second synchronous wheel 15.5 to rotate through the synchronous belt 15.6. At this moment, the intermittent clamping part 17 will not drive the fixed ring 16 to rotate, so as to meet the working needs. At this moment, after the switching rod 12.1 moves to the second working slot 12.3, the driving rod 7 at this moment will be connected to the fixing ring 16 through the connecting unit, and the fixing ring 16 will be driven to rotate by the driving rod 7, and then the second synchronous wheel 15.5 can be driven to rotate through the intermittent clamping piece 17, so that the first synchronous wheel 15.4 can be driven to rotate through the synchronous belt 15.6, so that the second speed gear 15.2 can be driven to rotate through the shaft 15.3, and then the first speed gear 15.1 can be driven to rotate through the second speed gear 15.2, so that the rotating rod 14 can be driven to rotate. When the rotating rod 14 rotates, the sprocket 13.2 of the rotating rod 14 will be driven to rotate, thereby driving the chain 13.1 to rotate, and the multiple sets of sprockets 13.2 are driven to rotate synchronously through the chain 13.1, so that the carrier tube 4 can be driven to rotate through the sprocket 13.2, which is convenient for the subsequent polishing operation of the gear workpiece 8.

[0050] In the embodiment provided by the present invention, the intermittent clamping member 17 includes a plurality of first clamping blocks 17.1 fixedly connected to the fixing ring 16, and also includes a plurality of second clamping blocks 17.2 arranged on the inner wall of the second synchronous wheel 15.5, and the first clamping blocks 17.1 correspond to the second clamping blocks 17.2 one by one. Specifically, the first clamping blocks 17.1 and the second clamping blocks 17.2 have the same shape and material, and the shapes of the first clamping blocks 17.1 and the second clamping blocks 17.2 are similar to wedge blocks, and the inclined surfaces of the first clamping blocks 17.1 and the second clamping blocks 17.2 are intermittently abutted. More specifically, the first block 17.1 and the second block 17.2 both include an elastic layer 19 and a hard layer 18. When the carrier 2 rotates, the second synchronous wheel 15.5 passively drives the plurality of first blocks 17.1 to rotate. The elastic layer 19 on the first block 17.1 will be squeezed and deformed with the elastic layer 19 on the second block 17.2. At this time, the rotation of the second synchronous wheel 15.5 will not drive the fixed ring 16 to rotate. On the contrary, when the driving rod 7 drives the fixed ring 16 to rotate, the rotation of the fixed ring 16 at this moment will drive the hard layer 18 on the second block 17.2 to abut against the hard layer 18 on the first block 17.1, thereby driving the second synchronous wheel 15.5 to rotate, and driving the first synchronous wheel 15.4 to rotate through the synchronous wheel, which is convenient for subsequent operations.

[0051] In the embodiment provided by the present invention, the connection unit includes a plurality of groups of plug rods 12.4 fixedly connected to the bottom of the driving rod 7, and a plurality of groups of slots 12.5 are provided on the fixing ring 16, and the plug rods 12.4 correspond to the slots 12.5 one by one. When the switching rod 12.1 is located inside the second station slot 12.3, each plug rod 12.4 is respectively inserted into the corresponding slot 12.5, so when the switching rod 12.1 moves from the first station slot 12.2 to the second station slot 12.3, the switching rod 12.1 at this moment will drive the driving rod 7 to slide downward, so that each plug rod 12.4 is respectively inserted into the corresponding slot 12.5, and when the driving rod 7 rotates, it will drive the fixing ring 16 to rotate, meeting the working needs.

[0052] In the embodiment provided by the present invention, more specifically, the gear fastening mechanism includes a fastening frame 21 fixedly connected to the bottom of the frame 1, and a screw 22 is fixedly connected to the fastening frame 21. A threaded barrel 23 is vertically slidably connected inside the bearing cylinder 4, and a limiting portion is provided between the threaded barrel 23 and the bearing cylinder 4, so that the threaded barrel 23 and the bearing cylinder 4 can only slide relative to each other, and cannot rotate relative to each other. Specifically, the threaded barrel 23 is threadedly connected to the screw 22, and when the bearing cylinder 4 rotates, it will drive the threaded barrel 23 to slide inside the bearing cylinder 4. A tightening block 25 is horizontally slidably connected to the bearing cylinder 4, and a pressure unit 24 is provided between the tightening block 25 and the threaded barrel 23. Specifically, a positioning groove 8.1 is provided on the gear workpiece 8, and the positioning groove 8.1 must be provided when the gear workpiece 8 is used later, so as to facilitate the installation of the gear workpiece 8 on a predetermined device later. The abutment block 25 is matched with the positioning groove 8.1. During use, the pressure unit 24 is used to drive the abutment block 25 to slide, so that the gear workpiece 8 can be fixed. During operation, when the bearing tube 4 rotates passively, it will drive the threaded tube 23 to slide inside the bearing tube 4. During the sliding stroke, the threaded tube 23 will drive the abutment block 25 to slide through the pressure unit 24. The gear workpiece 8 is fixed by the abutment between the abutment block 25 and the positioning groove 8.1. On the one hand, the gear workpiece 8 can be driven to rotate during the rotation of the bearing tube 4, thereby improving the stability of the gear workpiece 8 during rotation. On the other hand, after the gear fastening mechanism fixes the gear workpiece 8, it can reduce the shaking of the gear workpiece 8 when the polishing mechanism 3 is performing the polishing operation, and can further improve the stability of the gear workpiece 8 during the polishing operation, resulting in a better use effect.

[0053] In the embodiment provided by the present invention, the pressure unit 24 includes a connecting rod 24.1 fixedly connected to the threaded barrel 23, a first wedge block 24.2 fixedly connected to the connecting rod 24.1, a second wedge block 24.3 fixedly connected to the abutting block 25, and the first wedge block 24.2 abuts against the second wedge block 24.3. Specifically, when the threaded barrel 23 slides, it will drive the first wedge block 24.2 to slide upward, and then drive the second wedge block 24.3 to slide horizontally, so that the abutting block 25 slides toward the side close to the positioning groove 8.1, fix the gear workpiece 8, and meet the working needs.

[0054] In the embodiment provided by the present invention, a reset member is provided between the abutting block 25 and the bearing tube 4, so as to facilitate the sliding of the abutting block 25 to the side away from the gear workpiece 8, thereby facilitating the disassembly of the gear workpiece 8 at a later stage. The reset member includes a reset spring 26 installed between the abutting block 25 and the inner wall of the bearing tube 4. When no external force is applied to the second wedge block 24.3, the reset spring 26 restores its elastic deformation and drives the abutting block 25 away from the positioning groove 8.1, thereby unlocking the gear workpiece 8. Specifically, a torque spring is provided between the rotating rod 14, the shaft rod 15.3 and the rotating frame 5, and the elastic force of the torque spring drives the abutting block 25 away from the positioning groove 8.1. Therefore, when the connecting unit is not connected to the fixing ring 16, the elastic force of the torque spring drives the rotating rod 14 and the shaft rod 15.3 to rotate in the opposite direction, thereby driving the threaded cylinder 23 to slide downward. When the threaded cylinder 23 slides downward, it will drive the connecting rod 24.1 to slide downward, so that the first wedge block 24.2 is away from the second wedge block 24.3, that is, the clamping block 25 loses external pressure. At this moment, when there is no external force exerting pressure on the second wedge block 24.3, the return spring 26 drives the clamping block 25 away from the positioning groove 8.1 in the process of restoring the elastic deformation, so as to facilitate the unlocking of the gear workpiece 8 after processing, and then the gear workpiece 8 can be removed from the carrier plate 4.1, and the use effect is achieved.
