Description

Technical Field

[0001] The utility model relates to the technical field of screw processing, and more specifically, to a fixing fixture for screw processing. Background Art

[0002] A lead screw is a mechanical transmission device, usually consisting of a threaded rod and a nut. The threaded rod has threads, and when the nut moves along the threaded rod, it can convert rotational motion into linear motion, or vice versa. Lead screws are often used in engineering machinery, CNC machine tools and other equipment that require precise linear motion. Their characteristics include high transmission efficiency, precision and load capacity. In the process of producing lead screws, a shearing device is often required to cut the lead screw in order to obtain the required length of the lead screw. However, some existing cutting devices for lead screw production usually have the fixture for fixing the lead screw in a fixed position. Therefore, the staff needs to constantly loosen the fixture to assist in pushing the lead screw material to the appropriate shearing position, resulting in cumbersome processing steps and seriously affecting production efficiency.
