Abstract

The invention relates to a tool cutting edge wear detection clamp and belongs to the field of tool detection tools. The clamp is particularly suitable for detection of the cutting edge of a fiber reinforced composite hole drilling tool, and comprises a base, a bracket, an indexing disc, a gear assembly, a pressing assembly and a clamping cylinder assembly, wherein a scribed line group for accurately indicating the circumferential rotation angle of the clamp, a scribed line group for accurately positioning the degree of the pitching angle of a tool and indicating the pitching angle of the indexing disc and a clamping cylinder angle scribed line for accurate reading, positioning and tool setting in coordination with the mark of a tool handle are engraved on the clamp. The clamp is fastened by a fastening screw and a knob locking mechanism. The clamp is simple in structure, compact and smart, and parts are convenient to dismount, mount and clamp. The clamp is prevented from loosening andslipping in the measurement process, and tool detection efficiency and accuracy are improved.

Description

technical field [0001] The invention belongs to the field of tool detection tools, and relates to a tool cutting edge wear detection jig, which is especially suitable for detecting the cutting edge of a fiber reinforced composite material drilling hole making tool. Background technique [0002] Fiber-reinforced composite materials are widely used in many fields due to their light weight, high strength, corrosion resistance, and fatigue resistance. In order to meet the assembly requirements of composite components, a large number of drilling operations are required. However, its fiber-reinforced phase is highly abrasive, and it is easy to scratch the tool during drilling, resulting in rapid degradation of the cutting edge and reduced tool life. After the tool is worn out, it is not conducive to fiber cutting, affects the quality of the hole wall and causes damage such as delamination, tearing and burrs at the exit. In addition, the increased friction between the tool and the...
