Embodiment Construction

[0017] The present invention provides a test method for mechanical repeat positioning accuracy. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the following examples are given to further describe the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Mechanical repeat positioning accuracy test plan, using two dial gauges to measure in the visual positioning and closing gland robot station; the working area is 185x230mm2; the mechanical structure of the repeating motion includes the ball screw and the driven mechanical structure, every time it goes to Repeat the positioning position, use the striker to detect the mechanical structure at the positioning position, use the servo motor and servo driver, because the servo motor has no accumulated error during the walking process, so i...

Abstract

The invention discloses a method for testing the repeated positioning accuracy of a machine. Four target points with typical features are found in a working area. Then, followed are four steps: Step 1, respectively fixing two dial indicators on X-stroke and Y-stroke guide rails at one target point, so as to measure the precision numerical value of X-axis and Y-axis strokes; Step 2, making fine adjustment of points of the dial indicators in the X and Y rectangular coordinate system, and regulating the indication numerical value; Step 3, randomly finding four different starting points near each target point, and testing the repeated positioning accuracy from each starting point to the target point; and Step 4, repeating the steps 1-3 and testing the other three target points. In this way, bottlenecks that the repeated positioning accuracy cannot be measured after installation of mechanical structures are fixed, and theoretical basis is provided for calculation of electrical parameters of products by means of feedback of measurement results of the repeated positioning accuracy of mechanical structures.

Description

technical field [0001] The invention belongs to the technical field of electrical automation, is applied to the repeat positioning accuracy test of a servo-driven mechanical structure, and in particular relates to a test method for mechanical repeat positioning accuracy. Background technique [0002] In view of the weak technical level of domestic mechanical processing and installation, the gap between the processing and installation and the original precision requirements is obvious. Through the implementation of the control and detection mechanism of the automation system, the repeated positioning accuracy is tested, and the calculation and control of the position of the electrical engineering control mechanical structure is optimized and improved. The invention realizes the test of the repeated positioning accuracy of the mechanical structure and the distribution of the devices. Contents of the invention [0003] The purpose of the present invention is to provide a tes...
