A milling cutter positioning and clamping device for machine vision inspection

Abstract

A milling cutter positioning and clamping device for machine vision inspection, including a base, on which is provided a first slider driven by an X-axis stepping motor through an X-axis screw, a pedestal is installed above the first slider, and a pedestal is installed above the pedestal. There is a milling cutter clamp driven by a Y-axis stepping motor through a Y-axis screw, and an LED backlight is installed above the pedestal; beside the milling cutter clamp, there is a rotating clamp connected to the rotating spindle, which is driven by the R-axis Driven by a stepping motor, the R-axis stepping motor is fixed on the second slider; the second slider is driven by a Z-axis stepping motor through a Z-axis screw, and a milling cutter conveying device is arranged above the pedestal, and the equipment includes four degrees of freedom , the present invention can realize the image acquisition of the main and auxiliary cutting edges of the tested milling cutter, can realize no-fixture shooting, and can also realize the flow detection of the milling cutter, has a high degree of automation, and improves the detection accuracy and efficiency.

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
