Abstract

The invention discloses a rachet looseness prevention high-precision fine adjusting clamp, and belongs to the field of clamps. The rachet looseness prevention high-precision fine adjusting clamp comprises a clamp seat, a left fixing block, a left screw rod, a left clamping block, a right clamping block, a guide rod and a right fixing block. A dovetail groove is formed in the clamp seat, and the two ends of the dovetail groove are provided with the left fixing block and the right fixing block respectively. The rachet looseness prevention high-precision fine adjusting clamp further comprises a driven connecting rod, a left spring, a driving connecting rod, a right spring, a transmission rod, a right screw rod, a handle and rachet looseness prevention devices. The right screw rod and the left screw rod are respectively provided with one rachet looseness prevention device. One end of the driven connecting rod is hinged to the clamp seat, the other end of the driven connecting rod is connected with the driving connecting rod through the transmission rod, and the end, close to a hinge, of the driving connecting rod is connected with the guide rod. The rachet looseness prevention high-precision fine adjusting clamp solves the problems that an existing clamp is not prone to fine adjusting, 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 type high-precision fine-tuning 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 cont...
