Milling cutter positioning clamping equipment for machine vision detection

Abstract

The invention discloses milling cutter positioning clamping equipment for machine vision detection. The milling cutter positioning clamping equipment comprises a base, wherein a first side block driven by an X-axis step motor through an X-axis lead screw is arranged on the base; a table seat is arranged above the first side block; a milling cutter clamp block driven by a Y-axis step motor througha Y-axis lead screw is arranged on the table seat; an LED backlight source is arranged on the table seat; a rotating clamp block connected onto a rotating main shaft is arranged beside the milling cutter clamp block; the rotating main shaft is driven by a R shaft step motor; the R shaft step motor is fixed on a second slide block; the second slide block is driven by a Z-axis step motor through a Z-axis lead screw; a milling cutter conveying device is arranged above the table seat; the equipment has four freedom degrees. The milling cutter positioning clamping equipment has the advantages thatthe image collection on main and sub cutting edges of a milling cutter to be tested can be realized; the clamp-free shooting can be realized; the production line detection of the milling cutter can also be realized; the automation degree is high; the detection precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of machine vision precision measurement, in particular to a milling cutter positioning and clamping device for machine vision detection. Background technique [0002] Milling cutter is a tool used in milling, mainly used for processing planes, steps, grooves, forming surfaces and cutting off workpieces. Since the working environment of the milling cutter is extremely complex, wear and damage are always unavoidable, so regular inspection work is a necessary condition to ensure the normal operation of the milling cutter. With the rise of machine vision inspection technology, milling cutter positioning and clamping equipment is often used in the grinding and breakage of milling cutters to provide a better inspection environment and improve inspection efficiency and inspection accuracy. The shortcomings of today's milling cutter positioning and clamping equipment are as follows: (1) Most of the milling cutter p...

AI Technical Summary

Problems solved by technology

The shortcomings of today's milling cutter positioning and clamping equipment are as follows: (1) Most of the milling cutter positioning and clamping equipment currently used for machine vision inspection is still in the laboratory research stage, and there are very few that can be used for actual testing

(2) Because machine vision detection has high requirements on the light source environment, the image acquisition process of the milling cutter needs to use a backlight, and the only milling cutter positioning and clamping equipment currently uses a manipulator to hold the milling cutter for shooting. In this way, there will be a manipulator in the collected images, which increases the difficulty of post-image processing, and seriously affects the detection results

(3) The degree of automation is not high, and flow testing cannot be performed. Most of them need to manually place the test piece on the clamping device, which will make the positioning of the test object inaccurate and affect the detection accuracy.

(4) The milling cutter positioning and clamping equipment used for machine vision inspection on the market can only complete the end face of the milling cutter (axial, secondary cutting edge) and the arc surface of the milling cutter (radial, main cutting edge) A clamping positioning, cannot complete the clamping positioning of the main and auxiliary cutting edges at the same time
