Clamp used for tool wear detection

Abstract

The invention provides a clamp used for tool wear detection, belongs to the field of tool detection devices, and relates to the clamp used for tool detection. The clamp is suitable for devices used for wear detection on tools for machining holes in carbon fiber reinforced composites. The clamp is composed of a tool clamping assembly, a support assembly, a rotating table assembly and a displacement working table assembly. A tool is accurately positioned and clamped through the tool clamping assembly. By means of the clamp, the small-range horizontal movement of a displacement working table in the X-Y plane is achieved in a manual mode, and rotation of three rotation assemblies in three axis directions is achieved in a manual mode. In the tool clamping assembly, a base is of a structure shaped like a Chinese character 'shan', a circular protrusion is arranged at the center of the base, circular holes are machined in the upper portions of the left side wall and the right side wall of the base respectively, annularly-carved base left side angle scales are formed in the top of the left side wall, and annularly-carved base right side angle scales are formed in the top of the right side wall. The clamp is simple in structure and convenient to operate, and the good measurement device is provided for accurate detection on tool wear.

Description

technical field [0001] The invention belongs to the field of tool detection equipment, and relates to a fixture for tool detection, which is especially suitable for a tool wear detection device for hole-making and machining of carbon fiber reinforced composite materials. Background technique [0002] At present, carbon fiber reinforced composite materials are widely used in the aerospace field to manufacture various structural parts due to their advantages of light weight and high specific strength. Due to the assembly requirements between structural parts, a large number of high-quality connections must be manufactured through machining. hole. However, carbon fiber is extremely abrasive, and the mechanical scratching during processing causes the Co binder in the cemented carbide tool to be damaged, and the leakage of the cemented carbide grain exacerbates the process of the tool body being peeled off. Rapid tool wear, manifested as cutting edge passivation and flank wear. ...
