Description

Technical Field

[0001] This application relates to the technical field of gear processing equipment, and in particular to a processing equipment and method for a main reduction gear blank. Background Art

[0002] In industrial manufacturing, between automation and precision control devices, a speed reducer is usually used to reduce and transmit the high-load rotational speed transmitted by the drive shaft of the power source. In the production of speed reducers, multiple sets of main reduction gears with different specifications are required to reduce the input power so as to output the required power.

[0003] When producing the main reduction gear blank, first, a through hole needs to be machined on the cylinder to facilitate the installation of the main reduction gear blank on the rotating shaft. After the through hole on the main reduction gear blank is machined, the main reduction gear blank needs to be placed on the workbench, and then the position of the main reduction gear blank is fixed by bolts. Finally, teeth are machined on the cylinder surface through a cutting device so that the teeth form a circle on the circumferential surface of the cylinder, thereby forming the main reduction gear.

[0004] When machining the teeth of the main reduction gear blank, first, the main reduction gear blank needs to be fixed on the workbench. After fixing, the machined main reduction gear needs to be removed, and then the unmachined main reduction gear blank is continued to be placed on the workbench. However, when machining and replacing the main reduction gear, the main reduction gear blank is not machined, and the entire cutting device runs under no-load, which is likely to cause waste of resources. Summary of the Invention

[0005] In order to improve the processing efficiency of the main reduction gear blank, this application provides a processing equipment and method for the main reduction gear blank.

[0006] In the first aspect, a processing equipment for a main reduction gear blank provided by this application adopts the following technical solution:

[0007] A processing equipment for a main reduction gear blank includes a mounting rack for placing the main reduction gear blank and a cutting device arranged on the mounting rack. The cutting device is used for machining the teeth on the main reduction gear blank. A rotating rack is arranged on the mounting rack. Multiple main reduction gear blanks are placed on the rotating rack. The rotating rack is rotatably connected to the mounting rack. A plurality of fixing components for fixing the position of the main reduction gear blank are arranged on the rotating rack. The fixing components correspond to the main reduction gear blanks one by one. When any one main reduction gear blank corresponds to the cutting device, the cutting device machines the main reduction gear blank.

[0008] By adopting the above technical solution, when machining the main reduction gear blank, the position of the main reduction gear blank is fixed by the fixing component, and then the rotating frame is rotated. The rotating frame drives the main reduction gear blank to rotate, so that the main reduction gear blank corresponds to the cutting device, and the cutting device machines the main reduction gear blank. When the machining of the main reduction gear blank is completed, the rotating frame is rotated to make the adjacent main reduction gear blank correspond to the cutting device. While machining the main reduction gear blank, the machined main reduction gear blank can be taken off the rotating frame, and then the unmachined main reduction gear blank is continuously placed on the rotating frame. Thus, when machining the main reduction gear blank, there is no need to shut down the machine when replacing the main reduction gear blank, thereby improving the machining efficiency of the main reduction gear blank.

[0009] Optionally, a plurality of limiting shafts for passing through the main reduction gear blanks are arranged on the rotating frame. The limiting shafts correspond to the main reduction gear blanks one by one, and the fixing component is arranged on the limiting shafts; a driving component for driving the limiting shafts to rotate is arranged on the rotating frame.

[0010] By adopting the above technical solution, when machining the main reduction gear blank, first place a plurality of main reduction gear blanks on the rotating frame, and each main reduction gear blank is sleeved on the limiting shaft to limit the position of the main reduction gear blank. Then, the main reduction gear blank on the limiting shaft is fixed by the fixing component to prevent the main reduction gear blank from rotating when machining the main reduction gear blank.

[0011] Optionally, the driving component includes a control shaft rotating on the mounting frame and a driving motor for driving the control shaft to rotate. The driving motor is arranged on the mounting frame, and a plurality of linkage components for enabling the control shaft to drive the limiting shaft to rotate are arranged on the rotating frame.

[0012] By adopting the above technical solution, when one tooth of the main reduction gear blank is machined, under the action of the linkage component, the driving motor drives the control shaft to rotate, and then the limiting shaft rotates, so that the limiting shaft drives the main reduction gear blank to rotate, and then the cutting device machines the teeth on the circumference of the main reduction gear blank.

[0013] Optionally, the linkage component includes a driving sleeve rotating on the limiting shaft, a connecting rod hinged on the driving sleeve, and a driving disk rotating on the rotating frame. One end of the connecting rod away from the driving sleeve is hinged at a non - central position of the driving disk. The driving sleeve is slidably connected to the rotating frame. A plugging groove for plugging the limiting shaft is formed on the end face of the control shaft. When the limiting shaft moves into the plugging groove, the control shaft drives the limiting shaft to rotate.

[0014] By adopting the above technical solution, when machining the main reduction gear blank, the driving disc rotates. Under the action of the connecting rod, the limiting shaft is driven to move, so that the limiting shaft is inserted into the insertion slot. Then, the control shaft rotates to drive the limiting shaft to rotate. Since the main reduction gear blank is fixed on the limiting shaft through the fixing component, the main reduction gear blank is driven to rotate when the limiting shaft rotates, thus making it more convenient to drive the main reduction gear blank.

[0015] Optionally, the fixing component includes a fixing block slidably arranged on the limiting shaft and a push rod for pushing the fixing block to extend out of the limiting shaft and abut against the main reduction gear blank. The push rod is arranged on the limiting shaft and slides along the length direction of the limiting shaft. The fixing block abuts against the push rod, and one end of the push rod close to the control shaft extends out of the limiting shaft for abutting against the bottom wall of the insertion slot.

[0016] By adopting the above technical solution, since the push rod extends out of the limiting shaft, when driving the limiting shaft to move, the push rod first abuts against the bottom wall of the insertion slot, and then the limiting shaft continues to move, driving the fixing block to abut against the push block. Thus, while the limiting shaft moves, the fixing block can be pushed to move, so that the main reduction gear blank is fixed on the limiting shaft through the fixing block, and it is more convenient to fix the main reduction gear blank.

[0017] Optionally, a plurality of fixing blocks are arranged on the limiting shaft, and the push rod pushes the plurality of fixing blocks to move simultaneously.

[0018] By adopting the above technical solution, when fixing the main reduction gear blank on the limiting shaft, push the push rod, and the push rod drives the plurality of fixing blocks to move simultaneously, so that the plurality of fixing blocks simultaneously abut against the main reduction gear blank, thereby improving the fixing strength of the main reduction gear blank on the limiting shaft.

[0019] Optionally, a reset elastic member for pushing the fixing block to move into the limiting shaft is arranged in the limiting shaft. One end of the reset elastic member is arranged on the fixing block, and the other end is fixed on the limiting shaft.

[0020] By adopting the above technical solution, after the machining of the main reduction gear blank is completed, the driving disc rotates to drive the driving sleeve and the limiting shaft to move away from the control shaft, and also drives the limiting shaft to drive the fixing block to move. When the fixing block abuts against the push rod, under the action of the reset elastic member, the fixing block is pulled to move into the limiting shaft, and at the same time, the main reduction gear blank falls under the action of gravity and finally abuts against the surface of the rotating frame. When both the limiting shaft and the push rod are disengaged from the insertion slot, rotate the rotating frame to drive the adjacent unprocessed main reduction gear blank to correspond to the cutting device, and then the control component connects the limiting shaft and the control shaft to drive the main reduction gear blank to continue rotating for machining.

[0021] Optionally, a second driving component for driving the rotating frame to rotate is arranged on the mounting frame.

[0022] By adopting the above technical solution, under the action of the second driving component, the rotating frame is driven to rotate, so that it is more convenient to align the main reduction gear blank and the cutting device.

[0023] Optionally, the second driving component includes a fixed shaft fixed on the rotating frame, a driven gear fixed on the fixed shaft, an incomplete gear rotatably mounted on the mounting frame, and a second driving motor for driving the incomplete gear to rotate. The fixed shaft is rotatably mounted on the mounting frame. The incomplete gear meshes with the driven gear, and the second driving motor is arranged on the mounting frame.

[0024] By adopting the above technical solution, the second driving motor rotates to drive the incomplete gear to rotate. The incomplete gear drives the driving gear to rotate, and then drives the fixed shaft and the rotating frame to rotate. Under the action of the incomplete gear, when the incomplete gear rotates one circle, the cutting device processes one main reduction gear blank.

[0025] In a second aspect, the present application also provides a processing method for a main reduction gear blank, adopting the following technical solution: S1: A plurality of main reduction gear blanks are sleeved on the limiting shaft;

[0026] S2: The rotating frame rotates to align one of the main reduction gear blanks with the cutting device;

[0027] S3: The driving disk rotates to insert the limiting shaft into the insertion slot, and the control shaft drives the limiting shaft to rotate;

[0028] S4: The fixing component fixes the main reduction gear blank on the limiting shaft;

[0029] S5: The cutting device processes the main reduction gear blank on the limiting shaft. After the cutting device finishes processing the main reduction gear blank, the limiting shaft disengages from the insertion slot, and the rotating frame is rotated to drive the adjacent unprocessed main reduction gear blank to be aligned with the cutting device;

[0030] S6: Repeat the steps of S1-S5 to process the main reduction gear blank. While processing, the processed main reduction gear blank on the rotating frame is taken off and an unprocessed main reduction gear blank is placed in.

[0031] By adopting the above technical solution, when processing the main reduction gear blank, first, one main reduction gear blank is installed on each limiting shaft. The linkage component connects the limiting shaft and the control shaft, so that the control shaft rotates to drive the limiting shaft and the main reduction gear blank on the limiting shaft to rotate, and then the cutting device processes the corresponding main reduction gear blank.

Detailed implementation manners

[0038] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0039] The embodiment of the present application discloses a processing device for a main reduction gear blank. Referring to Figure 1 , a processing device for a main reduction gear blank includes a mounting bracket 01, a rotating bracket 02 is arranged on the mounting bracket 01, the rotating bracket 02 is rotatably connected to the mounting bracket 01, a plurality of limiting shafts 03 are arranged on the rotating bracket 02, mounting holes are formed in the main reduction gear blank, the limiting shafts 03 are inserted into the mounting holes, a fixing component 1 is arranged on the limiting shafts 03, the fixing component 1 is used to fix the main reduction gear blank on the limiting shafts 03, and at the same time, a cutting device 3 is arranged on the mounting bracket 01. When any unprocessed main reduction gear blank on the rotating bracket 02 corresponds to the cutting device 3, the cutting device 3 processes the main reduction gear blank to form teeth on the main reduction gear blank.

[0040] Referring to Figure 1 and Figure 2, the rotating frame 02 includes a plurality of mounting rods 021, and the plurality of mounting rods 021 are arranged in a crosswise manner. In this embodiment, three mounting rods 021 are provided, and the three mounting rods 021 are arranged in a crosswise manner. A fixed shaft 04 is welded at the cross position of the mounting rods 021. The fixed shaft 04 is rotatably connected to the mounting frame 01. A second driving assembly 2 is provided on the mounting frame 01. The second driving assembly 2 is used to drive the fixed shaft 04 and the rotating frame 02 to rotate. Since the three mounting rods 021 are arranged in a crosswise manner, six limiting shafts 03 can be provided on the three mounting rods 021. The six limiting shafts 03 are evenly spaced along the circumferential direction of the fixed shaft 04; a main reduction gear blank can be mounted on each limiting shaft 03. After the cutting device 3 finishes processing one of the main reduction gear blanks, rotate the rotating frame 02 to make the adjacent unprocessed main reduction gear blank correspond to the cutting device 3. While the cutting device 3 is working, the processed main reduction gear blank on the rotating frame 02 can be removed, and at the same time, the unprocessed main reduction gear blank can be placed on the rotating frame 02, thereby realizing the replacement of the main reduction gear blank while processing and improving work efficiency.

[0041] Refer to Figure 1 and Figure 2 , the second driving assembly 2 includes a driven gear 21, an incomplete gear 22 and a second driving motor 23. The driven gear 21 is coaxially welded to the fixed shaft 04. The incomplete gear 22 meshes with the driven gear 21, and the incomplete gear 22 is rotatably connected to the mounting frame 01. The second driving motor 23 is fixed to the mounting frame 01 by bolts, and the output shaft of the second driving motor 23 is welded to the incomplete gear 22. The second driving motor 23 rotates to drive the incomplete gear 22 to rotate, thereby driving the fixed shaft 04, the driven gear 21 and the rotating frame 02 to rotate.

[0042] Refer to Figure 1 and Figure 2 , a controller is provided on the mounting frame 01. The controller is electrically connected to the second driving motor 23. A PLC is provided inside the controller. The rotation speed of the second driving motor 23 is controlled by the controller. In this embodiment, when the second driving motor 23 rotates to drive the incomplete gear 22 to rotate one circle, the rotating frame 02 is driven to rotate 60 degrees, so that the processed main reduction gear blank rotates in a direction away from the cutting device 3, and at the same time, the unprocessed main reduction gear blank corresponds to the cutting device 3, and the cutting device 3 continues to process the unprocessed main reduction gear blank.

[0043] Refer to Figure 1 and Figure 2, a support frame 05 is provided on the mounting frame 01, and the cutting device 3 is installed on the support frame 05. The cutting device 3 includes a rotating hob 31 rotatably connected to the support frame 05, a rotating motor 32 fixed to the support frame 05, and a driving cylinder 33 fixed to the support frame 05. The rotation axis of the rotating hob 31 is perpendicular to the rotation axis of the limiting shaft 03. The output shaft of the rotating motor 32 is coaxially welded to the rotating hob 31. The rotating hob 31 is driven to rotate by the rotating motor 32. The piston rod of the driving cylinder 33 is welded to the support frame 05, and the cylinder body is welded to the mounting frame 01.

[0044] Refer to Figure 1 and Figure 2 , when machining the main reduction gear blank, first place the main reduction gear blank below the rotating hob 31. The rotating motor 32 drives the rotating hob 31 to rotate, and at the same time, the driving cylinder 33 drives the support frame 05 to move towards the main reduction gear blank. The main reduction gear blank is machined and cut by the rotation of the rotating hob 31, so as to form teeth on the side of the main reduction gear blank.

[0045] Refer to Figure 1 and Figure 2 , in order to facilitate the machining of the teeth on the circumference of the main reduction gear blank, a driving component 4 is provided on the mounting frame 01. The driving component 4 is used to drive the main reduction gear blank fixed on the limiting shaft 03 to rotate. The driving component 4 includes a control shaft 41 and a driving motor 42. The axis of the control shaft 41 is parallel to the axis of the limiting shaft 03, and the control shaft 41 is rotatably connected to the mounting frame 01. The driving motor 42 is fixed to the mounting frame 01 by bolts, and the output shaft of the driving motor 42 is welded to the control shaft 41. The control shaft 41 is driven to rotate by the rotation of the driving motor 42.

[0046] Refer to Figure 1 and Figure 2 , a plurality of linkage components 5 are provided on the rotating frame 02. The linkage components 5 are used to connect the limiting shaft 03 and the control shaft 41, so that the limiting shaft 03 is driven to rotate when the control shaft 41 rotates. In this embodiment, six groups of linkage components 5 are provided, and each group of linkage components 5 corresponds to each limiting shaft 03 one by one. When any main reduction gear blank corresponds to the cutting device 3, the corresponding linkage component 5 can connect the corresponding limiting shaft 03 and the control shaft 41, so that a group of driving components 4 drives different limiting shafts 03 to rotate.

[0047] Refer to Figure 2 and Figure 3The limit shaft 03 is slidably connected to the mounting rod 021, and a plug-in slot 6 is provided on the end face of the control shaft 41. When the main reduction wheel blank and the cutting device 3 correspond, the limit shaft 03 corresponds to the plug-in slot 6, and then the linkage assembly 5 drives the limit shaft 03 to move into the plug-in slot 6; in order to facilitate the control shaft 41 to drive the limit shaft 03 to rotate through the plug-in slot 6, the cross-section of the plug-in slot 6 is set to a polygon. In this embodiment, the cross-section of the plug-in slot 6 is set to a hexagon. In this embodiment, the limit shaft 03 includes a mounting portion 031 and a plug-in portion 032. The mounting portion 031 and the plug-in portion 032 are integrally formed. The cross-section of the plug-in portion 032 is set to a hexagon, which is convenient for corresponding to the plug-in slot 6. The cross-section of the mounting portion 031 is set to a circle, which is convenient for connecting to the main reduction wheel blank.

[0048] Reference Figure 2 and Figure 3 The linkage assembly 5 includes a driving sleeve 51, a connecting rod 52 and a driving disk 53. The driving sleeve 51 is slidably connected to the mounting rod 021 and slides along the length direction of the limiting shaft 03. The driving sleeve 51 is sleeved on the limiting shaft 03, so that the limiting shaft 03 can only rotate on the driving sleeve 51. One end of the connecting rod 52 is hinged on the driving sleeve 51, and the other end is hinged on the non-center of the driving disk 53. The driving disk 53 rotates, and under the action of the connecting rod 52, the driving sleeve 51 and the limiting shaft 03 are driven to move in a direction away from or close to the plug-in slot 6. At the same time, a clearance groove 64 is opened on the mounting rod 021 to facilitate the rotation of the connecting rod 52 on the mounting rod 021.

[0049] Reference Figure 2 and Figure 3 When processing the main reduction wheel blank, first make one of the limit shafts 03, the main reduction wheel blank and the cutting device 3 correspond. At this time, the limit shaft 03 is above the control shaft 41, and the plug-in portion 032 on the limit shaft 03 corresponds to the plug-in slot 6. Then rotate the drive disk 53. The drive disk 53 rotates to drive the drive sleeve 51 and the limit shaft 03 to move toward the plug-in slot 6. When the drive disk 53 rotates 180 degrees, the plug-in portion 032 on the limit shaft 03 is completely moved into the plug-in slot 6, and then the rotation of the control shaft 41 can drive the limit shaft 03 and the main reduction wheel blank to rotate.

[0050] Reference Figure 3 and Figure 4, an installation groove 61 is formed on the limiting shaft 03, and the fixing assembly 1 is arranged in the installation groove 61. The fixing assembly 1 includes a fixing block 11 and a push rod 12. The fixing block 11 is slidably connected to the limiting shaft 03 and slides in a direction perpendicular to the length direction of the limiting shaft 03. The push rod 12 is inserted through the limiting shaft 03 and slides along the length direction of the limiting shaft 03. Both ends of the push rod 12 extend out of the limiting shaft 03. A push surface 62 is arranged on the push rod 12, and the push surface 62 abuts against the fixing block 11. Under the action of the push surface 62, the push rod 12 gradually increases in the direction away from the control shaft 41; when fixing the main reduction gear blank, push the push rod 12 so that the push surface 62 on the push rod 12 abuts against the fixing block 11. When continuing to move the push rod 12, the push rod 12 pushes the fixing block 11 to extend out of the limiting shaft 03 and abut against the inner wall of the installation hole on the main reduction gear blank, thereby fixing the position of the main reduction gear blank.

[0051] Referring to Figure 2 and Figure 3 , the push rod 12 extends out of the limiting shaft 03 under the action of gravity, and the lower end surface of the push rod 12 also extends out of the lower surface of the installation rod 021. At the same time, a limiting ring 63 is welded to the end of the push rod 12 away from the control rod. Under the action of gravity, the limiting ring 63 abuts against the upper surface of the limiting shaft 03; combined with Figure 4 , when the linkage assembly 5 drives the limiting shaft 03 to slide, the push rod 12 and the limiting shaft 03 move simultaneously. Since the push rod 12 extends out of the limiting shaft 03 under the action of gravity, when the limiting shaft 03 moves, the end surface of the push rod 12 first contacts the inner bottom wall of the insertion slot 6, and then the limiting shaft 03 continues to drive the fixing block 11 to move, so that the fixing block 11 abuts against the push surface 62. Thus, while the limiting shaft 03 moves, the main reduction gear blank on the limiting shaft 03 is fixed through the fixing block 11.

[0052] Referring to Figure 2 and Figure 4 , in order to improve the fixing strength between the limiting shaft 03 and the main reduction gear blank, an elastic rubber pad 7 is arranged on the side of the fixing block 11 facing away from the push rod 12. When the limiting shaft 03 completely moves into the insertion slot 6, the elastic rubber pad 7 is in a compressed state. At the same time, a plurality of fixing blocks 11 are arranged on the limiting shaft 03, and the plurality of fixing blocks 11 are evenly spaced along the circumferential direction of the limiting shaft 03. In this embodiment, three fixing blocks 11 are arranged, and the three fixing blocks 11 all abut against the push surface 62. When the push rod 12 moves, it drives the three fixing blocks 11 to move simultaneously.

[0053] Referring to Figure 4 and Figure 5, a reset elastic member 8 is arranged in the installation groove 61. The reset elastic member 8 is used to pull the fixed block 11 to move into the limiting shaft 03. In this embodiment, the reset elastic member 8 is set as a rigid elastic sheet. One end of the rigid elastic sheet is welded to the inner wall of the installation groove 61, and the other end is welded to the fixed block 11. When the fixed block 11 abuts against the inner wall of the installation hole on the main reduction gear blank, the rigid elastic sheet is in a stretched state. When the fixed block 11 and the pushing surface 62 no longer abut, the rigid elastic sheet pulls the fixed block 11 to move into the limiting shaft 03, thereby facilitating the removal of the processed main reduction gear blank from the limiting shaft 03.

[0054] Refer to Figure 2 and Figure 3 , when it is necessary to remove the processed main reduction gear blank, continue to rotate the driving disk 53. The driving disk 53 drives the driving sleeve 51 and the limiting shaft 03 to move away from the insertion slot 6. At this time, the limiting shaft 03 drives the fixed block 11 and the main reduction gear blank to move together. When the fixed block 11 no longer abuts against the pushing surface 62, the fixed block 11 resets under the action of the rigid elastic sheet. The main reduction gear blank abuts against the upper surface of the installation rod 021 under the action of gravity. Then the limiting shaft 03 continues to move. When the limiting ring 63 abuts against the end surface of the limiting shaft 03, the movement of the limiting shaft 03 drives the push rod 12 to move. When the driving disk 53 rotates another 180 degrees, both the limiting shaft 03 and the push rod 12 are completely separated from the insertion slot 6, thereby facilitating the rotation of the rotating frame 02, so as to process the adjacent unprocessed main reduction gear blanks.

[0055] Refer to Figure 1 and Figure 2 , a plurality of control motors 9 are arranged on the installation rod 021. The number of control motors 9 is the same as the number of limiting shafts 03, and the control motors 9 are welded at the centers of the driving disks 53. The rotation of the control motors 9 drives the driving disks 53 to rotate, thereby facilitating the driving of the limiting shafts 03. In this embodiment, each control motor 9 is electrically connected to the controller. Under the action of the controller, the driving disk 53 rotates 180 degrees. Then when the main reduction gear blank is processed, the driving disk 53 is driven to rotate another 180 degrees, and the limiting shaft 03 moves away from the insertion slot 6. This facilitates the rotation of the rotating frame 02 on the installation frame 01.

[0056] The implementation principle of the processing equipment for the main reduction gear blank in the embodiments of the present application is as follows: When processing the main reduction gear blank, the second driving component 2 drives the rotating frame 02 to rotate, so that the main reduction gear blank on the limiting shaft 03 corresponds to the cutting device 3. At this time, the limiting shaft 03 corresponds to the insertion slot 6. Then, control the motor 9 to drive the driving disc 53 to rotate. The driving disc 53 drives the driving sleeve 51 and the limiting shaft 03 to move, so that the limiting shaft 03 moves into the insertion slot 6 on the control shaft 41. Then, drive the motor 42 to rotate to drive the limiting shaft 03 and the main reduction gear blank to rotate, thereby facilitating the cutting device 3 to process the teeth on the circumference of the main reduction gear blank. After the processing is completed, the rotating frame 02 rotates, and the processed main reduction gear blank moves away from the insertion slot 6. Thus, the unprocessed main reduction gear blank corresponds to the cutting device 3. Therefore, while processing the main reduction gear blank, the processed main reduction gear blank on the rotating frame 02 can be removed, thereby reducing the time for installing the main reduction gear blank during processing, and thus improving the processing efficiency of the main reduction gear blank.

[0057] The present application also provides a processing method for the main reduction gear blank, which adopts the following steps:

[0058] S1: A plurality of main reduction gear blanks are passed through the limiting shaft 03 through the mounting holes, so that the lower surface of the main reduction gear blank abuts against the upper surface of the mounting rod 021;

[0059] S2: The second driving component 2 drives the rotating frame 02 to rotate by 60 degrees, so that one of the main reduction gear blanks corresponds to the cutting device 3. At this time, the incomplete gear 22 and the driven gear 21 are no longer engaged;

[0060] S3: Control the motor 9 to rotate, drive the driving disc 53 to rotate, move the limiting shaft 03 into the insertion slot 6, and make the control shaft 41 drive the limiting shaft 03 to rotate;

[0061] S4: The fixing component 1 fixes the main reduction gear blank on the limiting shaft 03. When the limiting shaft 03 moves, it drives the fixing block 11 to abut against the pushing surface 62. Under the action of the pushing surface 62, the fixing block 11 is pushed to abut against the inner wall of the mounting hole on the main reduction gear blank;

[0062] S5: The cutting device 3 processes the main reduction gear blank on the limiting shaft 03. After the processing of the main reduction gear blank is completed, the driving disc 53 drives the limiting shaft 03 to disengage from the insertion slot 6, and rotates the rotating frame 02 to drive the adjacent unprocessed main reduction gear blank to correspond to the cutting device 3;

[0063] S6: Repeat the steps of S1 - S5. While processing, remove the processed main reduction gear blank on the rotating frame 02, and then put in the unprocessed main reduction gear blank to facilitate subsequent processing.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
