Pressure-detectable limiting looseness-prevention high-precision fine adjustment fixture

Abstract

The invention discloses a pressure-detectable limiting looseness-prevention high-precision fine adjustment fixture, and belongs to the field of fixtures. The pressure- detectable limiting looseness-prevention high-precision fine adjustment fixture comprises a fixture base, a left fixing block, a left screw, a left clamping block, a right clamping block, a guide rod and a right fixing block, the fixture base is provided with a dovetail groove, and the left fixing block and the right fixing block are arranged at the two ends of the dovetail groove respectively. The pressure- detectable limiting looseness-prevention high-precision fine adjustment fixture further comprises a driven connecting rod, a left spring, a driving connecting rod, a right spring, a transmission rod, a right screw, a handle, limiting looseness-prevention devices and sensors. The limiting looseness-prevention devices are arranged on the right screw and the left screw respectively and the sensors are arranged on the left clamping block and the right clamping block respectively. The pressure-detectable limiting looseness-prevention high-precision fine adjustment fixture solves the problems that in an existing fixture, fine adjustment is uneasy, locating precision is low, looseness is prone to occurring and clamping force is uneasy to control 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 pressure-measurable limiting and anti-loosening 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 mak...
