High-precision fine adjustment clamp

Abstract

The invention discloses a high-precision fine adjustment clamp, and belongs to the field of clamps. The high-precision fine adjustment clamp comprises a clamp base, a left fixing block, a left screw, a left clamping block, a right clamping block, a guide rod and a right fixing block, wherein a dovetail groove is formed in the clamp base, and the left fixing block and the right fixing block are arranged at the two ends of the dovetail groove. The high-precision fine adjustment clamp further comprises a driven connection rod, a left spring, a driving connection rod, a right spring, a transfer rod, a right screw and a handle, wherein one end of the driven connection rod is hinged to the clamp base, the other end of the driven connection rod is connected with the driving connection rod through the transfer rod, and one end, close to a hinge, of the driven connection rod is connected with the guide rod. The high-precision fine adjustment clamp solves the problems that by means of an existing clamp, fine adjustment is difficult, and locating precision is low. The high-precision fine adjustment clamp 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 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 control the clamping force. I...
