[0002] The synchronous pulley is a gear that meshes with the synchronous belt. The synchronous pulley needs to go through multiple processing processes such as turning, hobbing, and grinding burrs. The synchronous pulley is fixed by a fixed plate during processing.

[0003] The existing synchronous belt pulley fixing plate passes through the central axis hole of the synchronous belt pulley through a pipe rod, and the pipe rod completes the work of clamping the synchronous belt pulley by screwing the nut component. The nut component needs to be disassembled again each time the synchronous belt pulley is processed, which increases the number of parts that need to be disassembled each time the synchronous belt pulley is installed, making the installation and fixing more cumbersome, and the time for each disassembly and installation of the synchronous belt pulley is long. Summary of the invention

[0007] In at least some embodiments, the tail end of the upper support rod and the outer support fixing bar rotate, the lower support rod and the upper support rod are arranged opposite to each other in an eight-shaped shape, the middle sliding rod drives the upper support rod to move downward, the upper support rod supports the outer support fixing bar to move outward, and the middle sliding rod simultaneously drives the outer clamping block and the outer support fixing bar to move outward.

[0008] In at least some embodiments, a middle slide rod slides through the center of the upper fixed ring frame, a rotating outer support rod is arranged in an outer ring array on the upper end of the middle slide rod, and a sliding outer clamping block is arranged in an outer ring array in the middle of the upper fixed ring frame.

[0011] In at least some embodiments, when the middle sliding rod moves downward, the outer support fixing strip moves toward the side away from the middle sliding tube, the outer support fixing strip and the synchronous pulley are separated and no longer in contact, the outer clamping block moves toward the side away from the middle sliding rod, the outer clamping block shrinks to be flush with the outer side of the upper fixed ring frame, and the outer support fixing strip shrinks toward the center at the same time, and the outer clamping block and the upper fixed ring frame are both smaller than the axial hole of the synchronous pulley.

[0012] The utility model provides a synchronous pulley processing fixed disk, which has the following beneficial effects:

[0013] The electric telescopic cylinder drives the middle slide bar to move axially downward, and the middle slide bar drives the outer clamping block and the outer support fixing strip to move outward at the same time. The outer support fixing strip and the inner side of the synchronous belt pulley shaft hole are fitted together for fixation, and the outer clamping block and the outer side surface of the synchronous belt pulley are fitted together for axial fixation, completing two-way fixation, accelerating the fixing speed, and improving the fixing efficiency.
