[0024] In the technical scheme (as shown in Figure 1 , Figure 2 and Figure 3 ), each abutting frame 23 is fixedly installed with transmission rod 35 on the side, and transmission rod 35 is slidingly inserted into the inside of the side of hollow frame 13, the top end of each transmission rod 35 is fixedly installed with sliding frame 36, sliding groove 34 is formed in the middle of the side of hollow frame 13, and sliding frame 36 and transmission rod 35 are slidingly inserted into the inside of sliding groove 34, and pushing mechanism is arranged in the inside of hollow frame 13, and the transmission of the outer side of pushing mechanism is connected with sliding frame 36.
[0025] In the technical scheme (as shown in Figure 1 , Figure 2 and Figure 3 ), pushing mechanism includes rotating screw 3 and pushing rod 33, rotating screw 3 is vertically rotatably installed in the inside of hollow frame 13 through bearing, servo motor 37 is fixedly installed on the top of the outside of hollow frame 13, the bottom of the transmission shaft of servo motor 37 is fixedly connected with the top of rotating screw 3 through coupling, lifting sleeve 31 is movably sleeved on the top of the outside of rotating screw 3 through screw thread, connecting block 32 is fixedly installed on the outside surface of each lifting sleeve 31, pushing rod 33 is hingedly connected with the bottom of each connecting block 32 through rotating shaft, and the top of sliding frame 36 is hingedly connected with the bottom of pushing rod 33 through rotating shaft.
[0026] In the technical scheme (as shown in Figure 1 , Figure 2 and Figure 3As shown), each clamping frame 23 has a movably mounted fitting plate 25 on its inner top. The top of the clamping frame 23 is provided with an adjustment mechanism, which is connected to the top of the fitting plate 25 via a transmission. The adjustment mechanism includes an adjustment bolt 24. Each clamping frame 23 has an adjustment bolt 24 threaded through and screwed into its middle top. The bottom of the adjustment bolt 24 is inserted into the top of the fitting plate 25 via a bearing. Each fitting plate 25 has guide rods 26 vertically fixedly mounted on both sides of its top. Each clamping frame 23 has guide grooves 27 vertically opened on both sides of its top. The guide rods 26 are slidably inserted into the guide grooves 27.
[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), a retaining frame 23 is movably installed on all four sides of the hollow frame 13. A guide mechanism is provided inside the hollow frame 13, and the guide mechanism is connected to the outer side of the retaining frame 23. The guide mechanism includes a guide frame 2. The guide frame 2 is fixedly installed on the bottom inner side of the hollow frame 13. A sliding plate 21 is slidably installed inside the side of the guide frame 2. There are four sets of sliding plates 21.

[0028] During operation, the gear workpiece to be processed is fitted onto the outside of the hollow frame 13. The gear workpiece is then pressed down so that the clamping frame 23 is positioned on the outer side of the inner wall of the gear workpiece. Subsequently, the servo motor 37 is activated via an external control switch, causing it to rotate and drive the rotating lead screw 3 to rotate synchronously inside the hollow frame 13. Combined with the guiding and limiting effect of the sliding groove 34 on the push rod 33, the lifting sleeve 31 can move vertically synchronously on the surface of the rotating lead screw 3.

The movement allows the inner wall of the clamping frame 23 to fit against the inner wall of the gear workpiece for abutment and limitation. Simultaneously, the adjusting bolt 24 at the top of the clamping frame 23 adjusts the contact plate 25 by turning it, and the guide groove 27 guides the guide rod 26 by sliding it. This causes the contact plate 25 to move vertically from the top of the gear workpiece for abutment and limitation, thus fully clamping and fixing the gear workpiece to the outside of the hollow frame 13. Then, the drive motor connected to the bottom of the mounting base 1 and the drive rod 11 rotates, causing the rotating disk 12 and the gear workpiece fixed on its surface to rotate and adjust their processing positions, allowing for processing at different positions on the outside of the gear workpiece.
