Abstract

The invention discloses a rachet looseness prevention fine adjusting clamp, and belongs to the field of clamps. The rachet looseness prevention fine adjusting clamp comprises a clamp seat, a left fixing block, a big screw rod, a left clamping block, a right clamping block, a guide rod, a fine adjusting screw rod , a right fixing block, rachet looseness prevention devices, a gear, an outer ring, a spring, a rachet and a screw. A dovetail groove is formed in the clamp seat, the left fixing block and the right fixing block are arranged at the two ends of the dovetail groove, the two ends of the fine adjusting screw rod are respectively provided with a thread, one end of the fine adjusting screw rod is arranged in a threaded hole of the guide rod, and the other end of the fine adjusting screw rod is meshed with a thread of the right fixing block. The rotating directions of the threads at the two ends of the fine adjusting screw rod are the same, and the big screw rod and the fine adjusting screw rod are respectively provided with one rachet looseness prevention device. The rachet looseness prevention fine adjusting clamp solves the problems that an existing clamp is not easy to adjust slightly, not high in positioning precision and prone to loosening, and has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of fixtures, and more specifically relates to a pawl anti-loosening fine-adjustment fixture for workpiece clamping. Background technique [0002] In the machinery manufacturing industry, machine tools are used to process various workpieces, and clamping tools are required to fix the workpieces during processing, so as to realize cutting processes such as outer circle, end face, thread and axial cutting. For parts with low machining accuracy, it can generally be adjusted directly on the machine table to realize positioning and clamping, and then the position of the part can be determined by setting the machining coordinate system. For workpieces that require high machining accuracy, the relative position of the workpiece and the turning tool must be repeatedly checked, so the positioning accuracy must be increased. At the same time, ordinary clamps cannot be fine-tuned, which makes it difficult to control the clamping...
