Problems solved by technology

The patent No. CN103115588A discloses a test bench for measuring the accuracy of an arc cam indexing mechanism with a variable center distance, and the patent No. CN103604602A discloses a dynamic performance test bench for an arc cam indexing mechanism. Both the detection device and the method are only for measuring the output accuracy of the arc indexing mechanism, but the detection of the profile accuracy of the arc indexing cam can only be realized by the three-coordinate machine, but the cost of the three-coordinate machine measurement is high and the efficiency is low , and the space composite cam needs to be removed from the automatic tool changer, which cannot meet the requirements of real-time online measurement

Abstract

The invention discloses a device and method for detecting the accuracy of the spatial compound cam profile surface of an automatic tool changing device. The device and method firstly realize the measurement of the precision of the spatial compound cam profile point based on four laser displacement sensors and an encoder, and then utilize the data Collect the data obtained by the upper computer and obtain the contour curve of the space compound cam, and calculate the variation law of the contour accuracy of the space compound cam with the number of tool changes; the device and method can realize the accuracy of the space compound cam profile of the automatic tool changer testing and quality assessment.

Description

technical field [0001] The invention belongs to the field of precision detection of an automatic tool changer, in particular to a device and method for detecting the precision of a space compound cam profile of an automatic tool changer. Background technique [0002] The space composite cam is a key part of the automatic tool changer, which consists of two parts: a plane groove cam and an arc indexing cam. The inserting and pulling out actions of the tool changing manipulator are driven by the planar groove cam mechanism, and the rotary action of the tool changing manipulator is driven by the arc surface indexing cam mechanism. The space composite cam is simple and compact in structure, light in weight, and saves space. Under the same conditions, the tool change time of the cam-type automatic tool changer is short, but it will also wear out after long-term use, resulting in changes in the shape of the cam profile, which in turn leads to The tool changing manipulator cannot ...
