Sharp blade strip cutter detection method and device

Abstract

The invention discloses a sharp blade strip cutter detection method and device. The method includes positioning a standard cutter in a reference position; allowing a detection head device to contact with the detection position, namely the front cutting blade, rear cutting blade or front cutter face, of the standard cutter, detecting the detection position of the standard cutter, and acquiring reference data; recording the reference data; positioning a cutter to be detected in the reference position, allowing the detection head device to detect the position of the cutter to be detected corresponding to the detection position of the standard cutter, comparing the detection data with the reference data, and outputting the comparison result. The detection of the shapes of multiple cutters is implemented, the error of the sharp blade strip cutter is controlled in the certain range effectively, and the detecting efficiency is improved effectively as compared with that of the single manual detection operation on the sharp blade strip cutter.

Description

technical field [0001] The invention relates to the technical field of blade detection equipment, in particular to a detection method and device for a pointed rack blade. Background technique [0002] When manufacturing hypoid gears and spiral bevel gears, face milling cutters or face hobbing cutters are mostly used, which include strip-shaped blades and disc-shaped cutter bodies. In the face milling cutter, the cutting blade is set in the cutter body, and the blade rotates with the cutter body. During each cutting and feeding process of the end milling cutter, a tooth can be formed on the surface of the workpiece to be processed into a gear. slot, then the tool is retracted and the workpiece is indexed to the next slot position to form the next slot. In the face hob, the cutting blade is arranged in the cutter head body, so that with each single cutting feed of the face hob and the timing of the workpiece rotation, all the tooth grooves of the workpiece are formed.

AI Technical Summary

Problems solved by technology

[0003] Since the blades are arranged according to a certain rule in the cutter head, the consistency of the pointed rack blades directly affects the accuracy of cutting the tooth grooves, which in turn affects the machining accuracy of the entire workpiece

[0004] However, in the process of blade processing, there will inevitably be errors

In order to avoid excessive errors and affect the processing effect, it is necessary to measure the cutting edge of each blade individually with a special tool, and complete the inspection through multiple comparisons. The detection process is cumbersome, making the detection efficiency low
