Abstract

The invention discloses a system and method for measuring the machining accuracy of the collar groove of the RV reducer planet carrier. The measuring device is arranged in the circumferential equal-divided hole of the workpiece to be measured, and includes a displacement sensor and a Z-shaped measuring turntable. The bottom surface fits with the bottom surface B of the circumferentially equally divided hole, the top surface of the tail of the measuring turntable fits with the top surface A of the collar groove of the circumferentially equally divided hole, and the contact surface between the end of the measuring turntable and the displacement sensor is a slope structure The displacement sensor can be rotated and compressed, and the displacement sensor is connected with the computer module through the data acquisition system. The invention has high accuracy and fast measurement speed. After the standard parts are calibrated, the distance from the top surface of the collar groove of the measured workpiece to the bottom surface of the circumferential equal-divided hole can be quickly measured on the production line, thereby ensuring the high-efficiency work of the production line.

Description

technical field [0001] The invention belongs to the technical field of RV reducer planetary frame measurement, and in particular relates to a system and method for measuring the machining accuracy of a collar groove of an RV reducer planetary frame. Background technique [0002] Compared with foreign advanced manufacturers, my country's industrial robots lack overall core technology breakthroughs, especially in terms of manufacturing technology and complete equipment, lack of high-precision, high-speed and efficient key component production lines. The core components of industrial robots include joint reducers, servo motors, drives and controllers. As one of the key parts of the robot, the joint reducer used as the transmission part determines the performance index of the robot, and its cost accounts for more than 30% of the cost of the whole machine, among which the RV reducer is the most widely used. [0003] The RV reducer is composed of the front stage of a planetary ge...
