Abstract

The invention relates to the technical field of robot detection, in particular to a simple robot precision detecting device and method. The device comprises a fixing base and a load block which is used for being installed at the tail end of a robot. The fixing base is provided with an X-axis dial indicator, a Y-axis dial indicator and a Z-axis dial indicator, wherein the axis of the measuring head of the X-axis dial indicator, the axis of the measuring head of the Y-axis dial indicator and the axis of the measuring head of the Z-axis dial indicator are perpendicular to one another; when the robot drives the load block to move to the fixing base, the load block separately abuts against the measuring head of the X-axis dial indicator, the measuring head of the Y-axis dial indicator and the measuring head of the Z-axis dial indicator. The simple robot accuracy detecting device and method have the advantages that the load block is driven by the robot to move to the fixing base, the three faces, perpendicular to one another, of the load block abut against the three dial indicators respectively, readings of the dial indicators are taken, the moving precision of the arms of the robot is detected through multimetering, the structure is simple, the operation is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of robot detection, in particular to a simple robot precision detection device and detection method. Background technique [0002] The robot zero position error is the main factor affecting the absolute positioning accuracy of the robot. The robot zero position error refers to the relative error value between the actual position and the theoretical position of each movable joint of the robot at the initial position (ie, the robot zero position value). The goal of robot zero calibration is to identify and compensate the zero error value. [0003] The existing robot precision performance testing technology is mainly tested by laser tracker and Dyna log robot performance testing equipment. The core technologies of the above two equipment are monopolized by foreign countries, and the price is as high as several million. The test method is more complicated, and the theoretical requirements for testers higher. ...
