[0002] As a commonly used component in existing mechanical transmission devices, synchronous pulleys are widely used in fields such as automobiles, laser engraving equipment, medical machinery, steel machinery, and various precision machine tools. A clamping device is a mechanism that enables a positioned workpiece to be reliably fixed on a positioning element throughout the machining process without changing its position. When clamping the workpiece, it is not allowed to damage the positioning of the workpiece, and it should have sufficient rigidity to ensure the necessary clamping force, but should not damage the machined surface of the workpiece, thereby ensuring machining accuracy.

It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Embodiment 1, please refer to Figures 1 - 4 , the present utility model provides a technical solution, a synchronous pulley processing clamping mechanism, including

[0023] A groove block 1, a limiting device 2 is fixedly welded at the center of the groove of the groove block 1. A fixed groove 7 is opened on the upper surface of the groove block 1. A clamping device 3 is engaged in the groove of the groove block 1. The fixed groove 7 is used to fix the clamping device 3. The clamping device 3 includes a moving block 31 and a clamping plate 32. The clamping plate 32 is used to clamp the synchronous pulley. A through hole is opened at the center position of one side of the moving block 31. A nut plate 4 is fixedly installed on one side of the moving block 31. The nut plate 4 is concentric with the through hole. A threaded rocker 5 is sleeved in the nut plate 4. The external thread cooperation between the nut plate 4 and the threaded rocker 5 generates a force to push the clamping device 3 to move, controlling the clamping and loosening of the clamping device 3.

[0024] The limiting device 2 includes a limiting plate 22 and a limiting column 21. A limiting hole 23 is opened on one side of the limiting plate 22. The threaded rocker 5 passes through the limiting hole 23, and the threaded rocker 5 is fixedly connected by a bearing. The fixed way of the bearing connection does not limit the rotation of the threaded rocker 5 while restricting the horizontal movement of the threaded rocker 5. The limiting column 21 is welded and fixed on the limiting plate 22. A circular tray is arranged on the limiting column 21. The circular tray can be used to place the synchronous pulley, facilitating the clamping of the clamping device 3. The limiting device 2 is an integral structure.

[0025] The splint 32 is fixed to the upper surface of the moving block 31 by screws. A V-shaped clamping groove is provided on one side of the splint 32. The design of the V-shaped clamping groove has good clamping ability for synchronous pulleys of different sizes. A rubber pad 33 is fixedly connected to the inner wall of the V-shaped clamping groove by bolts. Connecting holes corresponding to the bolts are provided on the rubber pad 33. The connecting holes are countersunk holes, and the nuts at the ends of the bolts are hidden in the countersunk holes. A number of uniformly distributed anti-slip protrusions are convexly provided on the surface of the rubber pad 33. The anti-slip protrusions are uniformly arranged in an array on the rubber pad 33. The rubber pad 33 fixed by bolts is convenient for disassembly and replacement, avoiding the decline of clamping ability caused by wear during long-term use. At the same time, the design of the anti-slip protrusions further increases the friction of the rubber pad 33 and enhances the clamping ability.

[0026] External threads are provided at both ends of the threaded rocker 5. The external threads at both ends of the threaded rocker 5 are reverse threads and are not connected. The design of the reverse threads can synchronously control the movement of the two moving blocks 31 of the clamping device 3 in different directions by rotating the threaded rocker 5 in one direction. Nut discs 4 are sleeved on the external threads at both ends of the threaded rocker 5. A Z-shaped rocker handle 51 is provided on one side of the threaded rocker 5. The rocker handle 51 is fixedly welded to one end of the threaded rocker 5. The design of the rocker handle facilitates the rotation of the threaded rocker 5 to control the clamping and loosening of the clamping device.

[0027] The nut disc 4 includes a disc 41 and a cylinder 42. A hole with the same inner diameter as that of the cylinder 42 is provided at the center position of the disc 41. The disc 41 is fixedly connected to the cylinder 42 and is concentric. The nut disc 4 is an integral structure. The structural design of the nut disc 4 facilitates the fixation of the nut disc 4 and the cooperation with the threaded rocker 5 at the same time. Threaded holes are provided on the surface of the disc 41. The nut disc 4 is threadedly fixed to one side of the moving block 31. Internal threads are provided in the cylinder 42, and the internal threads are adapted to the external threads of the threaded rocker.

[0028] Anti-slip buckles 6 are provided on the engaging surface between the splint 32 and the groove block 1. The design of the anti-slip buckles 6 can prevent clamping loosening caused by thread slipping after the clamping device 3 is clamped. The anti-slip buckles 6 are connected and fixed to the splint 32 by half-thread screws. The fixing method of the half-thread screws can fix the anti-slip buckles 6, and at the same time does not limit the movement of the anti-slip buckles 6 in a certain direction in the fixing groove 7, so that the anti-slip buckles 6 do not affect the clamping of the synchronous pulley by the clamping device 3 while avoiding clamping loosening. A number of fixing grooves 7 are provided and are opened on both sides of the groove of the groove block 1.

[0029] In actual use, the fixing groove 7 is used to fix the clamping device 3. The nut plate 4 and the nut rocker 5 are externally threaded to generate a force to push the clamping device 3 to move, controlling the clamping and loosening of the clamping device 3. The threaded rocker 5 is fixedly connected to the limiting hole 23 by a bearing. The fixed manner of the bearing connection can limit the horizontal movement of the threaded rocker 5 while not restricting the rotation of the threaded rocker 5. The circular tray can be used to place the synchronous pulley, facilitating the clamping of the clamping device 3. The design of the V-shaped clamping groove has good clamping ability for synchronous pulleys of different sizes. The rubber pad 33 fixed by bolt connection is convenient for disassembly and replacement, avoiding the decline of clamping ability caused by wear during long-term use. At the same time, the design of the anti-slip convex block further increases the friction of the rubber pad 33 and enhances the clamping ability. The external threads at both ends of the threaded rocker 5 are reverse threads and are not connected. The design of the reverse threads can synchronously control the movement of the two moving blocks 31 of the clamping device 3 in different directions by rotating the threaded rocker 5 in one direction. The design of the rocker handle facilitates the rotation of the threaded rocker 5 to control the clamping and loosening of the clamping device. The structural design of the nut plate 4 facilitates the fixation of the nut plate 4 and the cooperation with the threaded rocker 5. The design of the anti-slip buckle 6 can prevent the clamping from loosening due to thread slipping after the clamping device 3 is clamped. The anti-slip buckle 6 is fixedly connected to the clamping plate 32 by a half-thread screw. The fixed manner of the half-thread screw can fix the anti-slip buckle 6 while not restricting the movement of the anti-slip buckle 6 in a certain direction in the fixing groove 7, enabling the anti-slip buckle 6 not to affect the clamping of the clamping device 3 on the synchronous pulley and avoiding clamping loosening.
