Location degree quick detection device and measuring method

Abstract

The invention provides a location degree quick detection device and measuring method.The device comprises a substrate.The substrate is connected with a center guide sleeve and three circumferential guide sleeves evenly distributed along the circumference with the center guide sleeve as the circle center.First sensor probe holes are formed in the circumference of the center guide sleeve at the interval of 120 degrees, second sensor probe holes are formed in the circumference of each circumferential guide sleeve at the interval of 90 degrees, and the axis directions of the circle centers of two second sensor probe holes are consistent with the axis directions of the circle centers of the corresponding first sensor probe holes.During measuring, deviation between a standard element, center holes of measured pieces and installation holes of circumferential crankshafts can be obtained by obtaining data of 15 measuring points of the center holes of cycloidal gears or planetary frames and the installation holes of the circumferential crankshafts, and the distance between ideal positions and actual positions of the circle centers of the installation holes of the three circumferential crankshafts is calculated through coordinate translation.The location degree is obtained through derivation.According to the device and method, detection of a quality detection center is not needed, and efficient work of a production line is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of quality detection of a cycloidal wheel and a planet carrier of an RV reducer, and in particular relates to a position degree rapid detection device and a measurement method. Background technique [0002] The RV reducer is composed of the gear shaft of the first-stage involute planetary gear transmission part, the planetary gear and the crankshaft, cycloidal wheel, pin wheel, pin gear housing and planet carrier of the second-stage pendulum transmission part. As an RV reducer for robots, the transmission accuracy is one of its important performance indicators. However, the manufacturing error and assembly error of each part has a certain impact on the transmission accuracy of the RV reducer. Considering that the cycloid wheel and the planet carrier are the key components in the RV reducer, the eccentric error of the crank shaft hole has an important influence on the transmission accuracy of the RV reducer, ...

Problems solved by technology

However, the detection of special comprehensive gauges can only measure qualitatively, and cannot judge the direction; the coordinate measurement method of the flat plate is complicated and cumbersome, and it is time-consuming and long

Moreover, these two methods are no longer suitable for the needs of mass production

The three-coordinate measuring machine used today can detect and edit the measurement program to realize the automatic detection of the position of the part, effectively reducing human errors, and has good versatility, but the efficiency is low. It can only be used in the inspection center for random inspection, and is not suitable for industrial joints. In-line inspection on robot production line
