A motor test bench centering system

Abstract

The invention discloses a motor test bench centering system, which comprises two sets of centering slight adjustment devices in matched connection with the front side and the rear side of a base of test tooling respectively. Each set of centering slight adjustment device comprises an adjustment support, a horizontal coaxiality adjustment assembly, and a vertical coaxiality adjustment assembly, wherein the first part of the horizontal coaxiality adjustment assembly is fixed on the adjustment support, the second part is fixed on the test tooling, and the first part and the second part are matched for adjusting the position of the test tooling along the radial direction of the output shaft of the test tooling in a horizontal plane; the vertical coaxiality adjustment assembly is fixed on the adjustment support and can be in supporting connection onto the bottom part of the test tooling for adjusting the position of the test tooling in the vertical direction. According to the motor test bench centering system, the horizontal coaxiality adjustment assemblies and the vertical coaxiality adjustment assemblies of the two sets of centering slight adjustment devices carry out slight adjustment on the horizontal coaxiality and the vertical coaxiality between the output shaft of the test tooling and the output shaft of a dynamometer, the position adjustment amount can be precisely controlled, centering operation is simplified, and the centering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of new energy automobile parts testing, in particular to a motor test bench centering system used in the motor test bench construction process. Background technique [0002] During the production process of automobiles, each component needs to be tested to ensure its quality. The motor is tested through the motor test bench. The motor test bench is mainly composed of test tooling, dynamometer and fixed platform. The test tool and dynamometer are installed on the fixed platform, and the test tool is used to install the motor. Before the test, the position of the test fixture needs to be adjusted so that the output shaft of the test fixture is aligned with the output shaft of the dynamometer. The system alignment accuracy of the motor test bench directly affects the safety of the motor test. If the alignment deviation is large, accidents are likely to occur during the high-speed operation of the motor test be...

Problems solved by technology

Although this method can finally meet the alignment requirements, due to the unevenness of the tapping force and the uncontrollable position adjustment, repeated tapping adjustments and measurements are required. The process is very cumbersome, resulting in low alignment efficiency of the motor test bench. And then affect the operating efficiency of the test equipment
