Fixture for automatic screw tapping machine of screw rod

Abstract

When the clamp for the automatic screw tapping machine of the screw rod is used, firstly, the screw rod penetrates through a through hole to be directly inserted into a limiting groove for limiting, then an air cylinder is started to drive an output end of the air cylinder to enable a movable clamping plate to move towards a fixed clamping plate until the screw rod is clamped through a profiling clamping plate, and then the screw rod is tapped through a tapping machine. After tapping is completed, the output end of the air cylinder retracts to drive the movable clamping plate to move, and therefore the lead screw is loosened and taken out to complete tapping. According to the utility model, the correct position of the screw rod in the machining process can be ensured and is not influenced by the technical level of workers, so that a batch of screw rods can stably obtain the same machining precision; meanwhile, during use, the time for mounting the screw rod can be shortened, the auxiliary working hours are reduced, and the labor productivity is improved; and meanwhile, the screw rod is more convenient, labor-saving and safe to assemble and disassemble, the requirement on the technical level of workers is reduced, and the labor intensity of the workers can be reduced.
