Pressure measurable high-precision micro-adjusting clamp

Abstract

The invention discloses a pressure measurable high-precision micro-adjusting clamp, and belongs to the field of clamps. The pressure measurable high-precision fine-tuning clamp comprises a clamp holder, a left fixing block, a left screw rod, a left clamping block, a right clamping block, a guide rod, and a right fixing block, and also 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 pressure sensors, wherein one end of the driven connecting rod is hinged onto the clamp holder, and the other end of the driven connecting rod is connected with the driving connecting rod through the transmission rod; one end, close to a hinge, of the driven connecting rod is connected with the guide rod, and the pressure sensors are arranged on clamping surfaces of the left clamping block and the right clamping block. The pressure measurable high-precision micro-adjusting clamp provided by the invention solves the problems that micro-adjustment is uneasy, the clamping force is uneasily controlled and the positioning precision is low in the prior art, and has the advantages of simple structure, reasonable design, and easiness in manufacture.

Description

technical field [0001] The invention belongs to the field of fixtures, and more specifically relates to a pressure-measurable 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 t...
