[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-4A gear processing fixed tool comprises a base 1, a plurality of columns 9 are fixedly connected to the base 1, a plurality of columns 9 are fixedly connected to a workbench 4, a plurality of through grooves 6 are opened on the workbench 4 at equal intervals on the circumference, a plurality of through grooves 6 are connected with abutment blocks 5 through a limiting mechanism, the lower ends of the plurality of abutment blocks 5 are hinged with hinged rods 8, the lower ends of the plurality of hinged rods 8 are hinged with telescopic rods 3, the telescopic rods 3 are hydraulic telescopic rods, the telescopic rods 3 are fixedly connected to the base 1, and the telescopic rods 3 are extended and retracted to drive the inclination angles of the plurality of hinged rods 8 to be adjusted, so that the plurality of abutment blocks 5 abut against the tooth grooves of the gear, the gear is stuck and limited, and the gear is prevented from rotating, thereby ensuring the fixing effect during drilling, which is conducive to processing the inner hole of the gear.

[0020] The limiting mechanism includes a limiting rod 11, which is fixedly connected to the inner wall of the through groove 6. A limiting hole is provided on the abutment block 5. The limiting rod 11 is located in the limiting hole. When the telescopic rod 3 is extended and retracted, driving the tilt angle of the hinged rod 8 to change, it will drive the abutment block 5 to slide on the limiting rod 11.

[0021] A plurality of fixing holes are provided on the base 1 at equal intervals around the circumference, so that bolts can be matched with the fixing holes to fix the device.

[0022] When fixing the gear, the gear is placed on the workbench 4, the telescopic rod 3 is retracted, and the lower end of the hinged rod 8 is driven to move, so that the upper end of the hinged rod 8 pulls the abutment block 5 to move toward the axis of the telescopic rod 3, thereby causing the abutment block 5 to enter the tooth groove of the gear, fixing the gear and preventing the gear from rotating.

[0023] Example 2: Reference Figure 1-4 As another preferred embodiment of the present invention, on the basis of embodiment 1, a through hole 7 is fixedly connected to the workbench 4. The through hole 7 is used to accommodate the drill bit during drilling. A guide cover 10 is fixedly connected to the workbench 4. A collecting cylinder 2 is placed on the base 1. The guide cover 10 is used to guide the debris passing through the through hole 7 into the collecting cylinder 2 for collection. The debris remaining on the gear can also be swept into the inner hole of the gear and enter the collecting cylinder 2 through the through hole 7.

[0024] Example 3: Reference Figure 1-5 As another preferred embodiment of the present invention, on the basis of Example 2, a positioning groove 12 is provided on the bottom wall of the collecting barrel 2, and a positioning block 13 is provided in the positioning groove 12. The positioning block 13 is fixedly connected to the base 1. By using the positioning block 13 and the positioning groove 12, the position of the collecting barrel 2 can be positioned so that the collecting barrel 2 is located directly below the lower end of the guide cover 10 to facilitate the entry of debris.
