Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, and more specifically to a screw thread grinding and locking clamp. Background Art
[0002] When clamping products, different specifications of shaft clamps, fork rods, and blocks are usually used to lock the products. There are many types and they cannot be universally used. When processing products of a certain specification, the clamping process is relatively cumbersome. Improper operation of one link will cause deviations in the roundness and center diameter of the product. The existing product clamping method is to select a shaft clamp that matches the product specifications and fix it on the workpiece shaft end, install the blocks and forks that match the product on the main shaft end of the equipment, and then load the product into the block, adjust the appropriate position and lock it, and then process the product.
[0003] However, in this process, since the products to be clamped vary in size, the internal position of the block needs to be finely adjusted before the clamping operation. This process is time-consuming, resulting in a significant reduction in clamping efficiency, and also causing unstable and abnormal product accuracy. Utility Model Content
