Description

[0002] Synchronous pulleys are generally made of steel, aluminum alloy, cast iron, brass and other materials, and their inner holes are round holes, D-shaped holes, tapered holes and other forms. Synchronous pulley transmission consists of a closed ring belt with equally spaced teeth on the inner surface and a corresponding pulley. During the processing of synchronous pulleys, it is often necessary to punch holes between the teeth of the synchronous pulleys. During the punching process, the synchronous pulleys are prone to deflection and rotation, which will cause the holes to be skewed and misaligned, resulting in the scrapping of materials and accelerated grinding of the tool, so a fixture is required to clamp and fix it.

It is not convenient to adjust the height of the fixture, so it cannot adapt to the punching device of fixed height, and it is not convenient to move. After it is easy to move, the whole device is easy to shake due to the wheels when punching, so it is easy to hit off-center. Therefore, we propose a synchronous pulley punching fixture to solve the above problems. Utility Model Content
