Method and device for detecting edge wear of fully automatic forming milling cutter

Abstract

The invention discloses a full-automatic detection method and apparatus of a wearing capacity of a cutting edge of a formed milling cutter. The detection apparatus comprises a milling cutter that is installed on a cutter base rotation platform and can rotate around a self-rotation platform of the milling cutter, a visual inspection module for detecting a wearing width of a cutting edge of the milling cutter, a detection module X-direction translation bench for driving the visual inspection module to move along an X-axis direction, a detection module Y-direction translation bench for driving the visual inspection module to move along a Y-axis direction, a visual inspection module rotation bench for driving the visual inspection module to rotate horizontally, and a laser displacement sensorfor detecting the location of the cutting edge of the milling cutter. According to the invention, the wearing capacity of the formed milling cutter can be detected to provide a reference base for coping of the formed milling cutter. And the detection method and apparatus also can be used for detecting a diameter value of the cutter after coping.

Description

technical field [0001] The invention relates to a fully automatic detection device and detection method for the wear amount of the cutting edge of a forming milling cutter, which belongs to the field of milling cutter grinding for band saw blades. Background technique [0002] Profile milling is currently a common way to process bimetallic band saw blades and gears. The sawtooth forming method of the band saw blade generally uses a form milling cutter for milling. During the use of the serrated form milling cutter, after a period of use, the cutting edge will produce a certain width of the wear zone. When the wear area reaches a certain width, the cutting edge is no longer sharp and affects the processing quality. At this time, the wear area needs to be ground on a special tool grinder to obtain a new cutting edge. [0003] Taking the milling of bimetallic band saw blades as an example, when the wear width of the milling cutter edge reaches about 0.3mm, it must be reground...

AI Technical Summary

Problems solved by technology

If you use the naked eye or a magnifying glass to detect, you can't get the wear amount more accurately (generally around 0.3mm). If you test each cutting edge, it will take a lot of time

[0006] 2) There is a lot of waste, and it is impossible to ensure that the cutting edge is completely ground

Take the cutting edge wear of 0.3mm as an example, the grinding amount needs to reach about 0.35mm, in this case, about 16% of the cutting edge will be wasted
