On-machine multi-view visual detector for fine milling cutter and detection method of detector

Abstract

The invention relates to an on-machine multi-view visual detector for a fine milling cutter and a detection method of the on-machine multi-view visual detector. According to the on-machine multi-viewvisual detector for the fine milling cutter, through dual-protection design of positive air pressure and a pneumatic plunger, it is guaranteed that an optical element is not polluted in the severe machining environment with cutting fluid, oil mist and cuttings, and reliable operation is achieved. On the basis a telecentric optical parallel projection imaging principle, a semi-transparent semi-reflecting mirror is adopted, radial and axial observation visual angles can be realized at the same time by using a single camera; and three types of light sources of backlight, front light and glazing are utilized to automatically complete multiple functions of length and diameter measurement, fracture detection and radial and end part surface abrasion observation of the fine milling cutter, so thatfailure of the fine milling cutter is detected in time, the machining surface is prevented from being further damaged, and the machining precision is reduced.

Description

technical field [0001] The invention relates to the field of on-machine detection instruments for ultra-precision machining, in particular to an on-machine multi-view visual inspection instrument for micro milling cutters and a detection method thereof. Background technique [0002] On-machine detection of rotary tools involves five mutually independent functions, namely: tool setting, multi-view detection of micro-tools, tool runout detection, tooth-by-tooth wear detection of front and rear cutter faces, and real-time monitoring of the entire machining process. , the first four functions can only be run before and after machining, and the fifth function can monitor the tool status in the whole process of CNC machining in real time. a specific attribute. This paper only studies the independent function of multi-view detection of micro-tools. [0003] The micro milling cutter is a key part of ultra-precision milling. The size range is generally 0.01-1mm, and it has the char...
