Description

Technical Field

[0001] The present invention relates to the technical field of motor testing, and particularly to a testing tooling for motor prototypes. Background Art

[0002] Existing motor testing jigs have problems such as fixed clamping range, low installation efficiency, and poor compatibility of test interfaces. The traditional solution uses customized jigs, resulting in high testing costs and difficulty in meeting the rapid switching test requirements for motors of different sizes. Summary of the Invention

[0003] In view of the above problems, the present invention provides a testing tooling for motor prototypes, which realizes rapid positioning through symmetric jaws driven by a bidirectional lead screw, and cooperates with a universal coupling and a test interface module to effectively solve the compatibility problem of testing multiple models of motors.

[0004] The technical solution of the present invention is as follows:

[0005] A testing tooling for motor prototypes includes a base, an adjustable clamping mechanism, and a driving connection assembly; a transverse guide rail and a longitudinal positioning groove are provided on the base, the adjustable clamping mechanism is slidably connected to the transverse guide rail through a slider, and the driving connection assembly includes a universal coupling and a torque sensor mounting seat; a detachable cooling system is provided at the bottom of the base, including a cooling fan and a flow guide cover, and the outlet direction of the flow guide cover faces the heat dissipation holes of the motor prototype.

[0006] In a further technical solution, the adjustable clamping mechanism includes symmetrically arranged L-shaped jaws, a bidirectional lead screw, and a hand wheel. The bidirectional lead screw is fixed on the base through a bearing seat and is in threaded cooperation with the two L-shaped jaws.

[0007] In a further technical solution, a polyurethane buffer pad is provided on the inner side of the L-shaped jaw, and its contact surface has a serrated texture.

[0008] In a further technical solution, a magnetic positioning block is embedded in the longitudinal positioning groove, and a scale ruler is provided on the surface of the positioning block.

[0009] In a further technical solution, the cooling fan is connected to the bottom of the base through a slide rail, and the extending direction of the slide rail is parallel to the transverse guide rail. The cooling fan can move along the slide rail to different heat dissipation positions.

[0010] In a further technical solution, a modular mounting plate is provided on the base, and the mounting plate is fixed to the longitudinal positioning groove through quick-release bolts, and matrix-type threaded holes adapted to different motor mounting holes are distributed on its surface.

[0011] The beneficial effects of the present invention are:

[0012] 1. Improved clamping compatibility, capable of adapting to motor prototypes of different sizes, with an adjustment range covering common industrial motor specifications;

[0013] 2. Increased testing efficiency. Magnetic positioning and a two-way lead screw cooperate to achieve rapid tool change within 30 seconds;

[0014] 3. The heat dissipation efficiency is increased by 30%-50%, avoiding the over-temperature of the motor caused by long-term testing;

[0015] 4. Extended service life. The polyurethane buffer pad reduces the clamping stress and avoids damage to the surface of the prototype. Description of the Drawings
