[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figs. 1-2 As shown, the gear processing fixture of this embodiment includes a worktable 1 and support legs 2. A support plate 5 with a circular structure is provided in the middle of the worktable 1. Several clamping mechanisms 3 are provided at equal angles on the outer side of the worktable 1. The clamping mechanism 3 includes a fixed base 301, a sliding groove 302 opened on the fixed base 301, a sliding rod 303 provided in the sliding groove 302, a limiting ring 304 symmetrically fixed on the outer wall of the sliding rod 303, a rotating sleeve 305 between the limiting rings 304, a locking rod 306 fixed on the outer wall of the rotating sleeve 305, a locking groove 307 that cooperates with the locking rod 306, a spring 308 and a conical block 309 sleeved on the outer wall of the sliding rod 303. Several locking grooves 307 are provided at equal intervals on the top of the fixed base 301. This facilitates the placement of gears and ensures the stability of gear fixation.

[0022] Furthermore, a hydraulic cylinder 4 is fixedly installed at the bottom of the workbench 1, and one end of the top of the hydraulic cylinder 4 is fixedly connected to the support plate 5.

[0023] Furthermore, both ends of the slide rod 303 pass through the fixed seat 301 and are slidably connected to the fixed seat 301, and the conical block 309 is fixedly installed at one end of the slide rod 303 near the support plate 5.

[0024] Working principle: Rotate the clamping rod 306 and push it away from the support plate 5. During the rotation of the clamping rod 306, the clamping rod 306 will drive the rotating sleeve 305 to rotate, so it will not change the plane where the conical block 309 is located. Push the clamping rod 306 away from the support plate 5 and insert it into the corresponding slot 307. At this time, the conical blocks 309 are all away from the support plate 5. Then place the gear to be processed on the support plate 5. After the gear is placed, rotate the clamping rod 306 to disengage it from the slot 307. Then push the clamping rod 306 towards the gear side. The conical block 309 is inserted between the teeth at the root of the gear. Then push the conical blocks 309 in other positions that are aligned with the gaps between the teeth at the root of the gear towards the gear and clamp the clamping rod 306.
