[0052] The present invention is suitable for finishing after rough machining of gear shaping. When the tool meets the design requirements, and when the rough machining ensures the pitch error, the pitch error of the pin gear shell, and the cumulative pitch error, the position accuracy requirements can be guaranteed. First, the push cutter ensures the cylindricity requirements of the pin gear shell pin gear. Secondly, the guide of the tool is guided by the rough machining of the pin gear shell pin gear. This ensures that the original rough machining accuracy is improved by one level to meet the design requirements. Thirdly, the radial positioning of the tool uses the machining allowance of the adjacent pin gear teeth of the pin gear rough machining to determine the radial positioning size of the push cutter, ensuring the machining allowance of the push gear.
[0053] When the present invention is used, the tool is placed on a workbench that applies axial force to the push cutter, the needle tooth housing to be finely processed is placed on the support block 3, the needle tooth housing and the positioning plate 2 are rotated on the base 1, so that the needle tooth housing is rotated to the position of the tooth to be processed, and the locking handle 12 is rotated forward. The locking handle 12 drives the upper and lower locking blocks 11 to move away from each other through the threaded rod, so that the upper and lower locking blocks 11 release the guide rod 7. The guide rod 7 moves outward along the guide groove in the guide top seat 6 under the action of the compression spring 10, so that the positioning pin 1 8 and the two positioning pins 2 9 are always close to the top of the needle tooth circle of the needle tooth housing, ensuring that the push cutter is on the center circle of the needle tooth housing. In order to ensure that the tooth pushing process is not affected After positioning, the locking handle 12 is rotated in the opposite direction. The locking handle 12 drives the upper and lower locking blocks 11 to approach each other through the threaded rod, so that the upper and lower locking blocks 11 lock the guide rod 7 to ensure that the guide rod 7 will not move axially, and the positioning pin 1 8 and the two positioning pins 2 9 are always close to the needle tooth shell. The tooth pushing work is completed by pushing the push knife along the push knife positioning groove 14. When pushing the next tooth, loosen the locking handle 12, rotate the positioning disk 2 with the needle tooth shell, and the compression spring 10 can be compressed to move to the next tooth. After it is in place, tighten the locking handle 12 and repeat the above tooth pushing work. Repeat the tooth pushing process according to the design requirements. The present invention has a simple structure, flexible operation, and compact design. It ensures the center circle size of the needle tooth shell, facilitates the locking of the needle tooth shell, and realizes the guiding positioning of the push knife at the same time, meets the requirements of the processing accuracy of the needle tooth shell, has low cost, and meets the processing requirements of the needle tooth shell with a small number of processed teeth and a small production batch.
