Abstract

[0002] A pulley is a hub-type part that usually has a relatively large relative size. Its manufacturing process mainly includes casting and forging. Pulleys are mainly used to transmit power over long distances and are suitable for a variety of mechanical equipment, such as small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging machines, etc. There are many types of pulleys, including V-type pulleys, flat pulleys and toothed pulleys. V-type pulleys are the most common type and are suitable for drive auxiliary systems. During the processing, it is often necessary to use an external clamping device to clamp and fix the pulley, so as to facilitate subsequent processing. However, there are still some problems with the existing processing clamping devices when used:
[0003] 1. The loading steps are cumbersome. The existing pulley clamping device is cumbersome to operate during the loading, clamping and fixing process of the pulley. It requires multiple manual steps to effectively fix the pulley. This fixing method wastes a lot of time, thereby reducing work efficiency.
[0004] 2. Poor stability. After the existing pulley clamping device clamps and fixes the pulley, the external extrusion force during the processing, grinding and welding of the pulley will cause the pulley to deviate slightly, resulting in poor overall stability after fixation.

[0028] By utilizing the mutual cooperation between the fixed central axis 6 and the fixed insertion rod 18, it is only necessary to place the pulley to be processed in the middle, and use the squeezing of the two and the limiting fixation of the limiting blocks on both sides, so that the pulley can be quickly and effectively fixed by using a quick plug-in method.
[0029] A worm gear 9 is welded to the outer wall of the back of the rotating shaft 3, and a worm 10 is meshed with the bottom of the worm gear 9. A servo motor 11 is connected to the axis of the worm 10. A turntable 17 is rotatably provided on one side of the top of the support plate 15, and positioning pressure rods 20 are welded to the outer wall of the turntable 17 in a circular shape and distributed at equal distances.
[0030] A fixed rod 18 is welded at the axis of the turntable 17 , and a second limiting block 19 is welded to the outer wall of the end of the fixed rod 18 .
[0031] The outer walls at both ends of the bottom of the support plate 15 are penetrated with limiting holes 21, and the outer walls at both ends of the bottom of the fixing plate 2 are welded with symmetrically distributed guide rods 12;
