TDOF (three degree of freedom) dynamic and static loading integrated testing apparatus for linear motor

Abstract

The invention discloses a TDOF (three degree of freedom) dynamic and static loading integrated testing apparatus for a linear motor, which comprises six non-contact loading mechanisms, a testing platform, two linear guide rails, a loading supporting mechanism, two non-contact loading mechanism loaded bodies and two contact loading mechanisms. The two non-contact loading mechanism loaded bodies are symmetrically arranged in parallel at both sides of the top end face of a middle platform of the testing platform along the Y-axis direction. The two linear guide rails are symmetrically arranged inparallel on the top end face of the middle platform between the two non-contact loading mechanism loaded bodies. Four non-contact loading mechanisms are arranged on the upper surface and the bottom surface at both ends of a beam in the loading supporting mechanism. Two non-contact loading mechanisms are arranged on two end faces of a base in the loading supporting mechanism, and the two end facesare vertical to the X axis. Linear guide rail slots at both sides of the base in the loading supporting mechanism are in contact connection with the two linear guide rails. Both the ends of the beam in the loading supporting mechanism are in clearance fit with rectangular through holes on the two non-contact loading mechanism loaded bodies.

Description

technical field [0001] The invention relates to a loading test device for evaluating the reliability of a linear motor, more specifically, the invention relates to a three-degree-of-freedom dynamic and static loading comprehensive test device for a linear motor. Background technique [0002] At present, there are many types of linear motors, which are widely used in CNC equipment, industrial automation, rail transit and other industries. The performance test and test of the reliability of the linear motor is a necessary link before it is put into the market and applied, and the basis of the reliability test and test is to restore the real working condition of the linear motor and simulate the loading under its working state. This is of great significance for determining the key performance indicators of the linear motor drive, pointing out the defects of the equipment and improving the application level of the equipment. [0003] The existing typical test device is a linear...

AI Technical Summary

Problems solved by technology

[0005] 1. When the linear motor is loaded in the direction of motion, the mechanism is complex and the reliability is not high. At the same time, because the wire rope is used to seal the connection between the loading part and the part to be tested, the adjustment of the tightness of the wire rope is very critical, which brings many uncertainties to the relevant tests. Factors, which lead to slow test response, are not suitable for testing under high standards and strict requirements;

[0006] 2. It can only load or detect the direction of motion, and does not load the direction of non-motion, and cannot effectively simulate the motion of the linear motor under real working conditions.
