A water pump assembly dynamic effect test fixture

Abstract

The invention relates to a dynamic validation clamp of a water pump assembly. The dynamic validation clamp comprises an upper clamp body and a lower clamp body, the lower clamp body comprises a clamp body, a supporting plate and a support, a sealing ring is arranged on the surface of the clamp body, a mounting groove is formed in the center of the clamp body, a ventilation hole is formed in the bottom end of the mounting groove, the right end of the clamp body is connected with the support through the supporting plate, an air cylinder is arranged on the support, and a pen container is arranged at the front end of the supporting plate. The upper clamp body comprises an upper mould plate and rectangular spiral springs, the middle of the upper mould plate is connected with a motor shaft through a bearing, the lower end of the motor shaft is connected with a rotary disc, rotary shafts are symmetrically arranged at the lower end of the rotary disc, the lower ends of the rotary shafts are connected with pusher dogs, the two ends of the upper mould plate are each connected with a guide sleeve, guide rods are arranged in the guide sleeves, and the lower ends of the guide rods are connected with pressing rods. The dynamic validation clamp is high in automation degree, testing efficiency is improved, and meanwhile the facticity of a testing environment and the accuracy of a testing result are improved. Testing accuracy is guaranteed by stably clamping a pump body, and an air impermeability test on the pump body is achieved.

Description

technical field [0001] The invention relates to the field of testing jigs for auto parts, in particular to a dynamic effect testing jig for a water pump assembly. Background technique [0002] In the industry, the impeller is sealed into the pump body after processing. How is the working performance of the impeller in the pump body? Regarding this issue, because it is in the pump body, it is difficult to use a set of instruments or methods to make an accurate assessment of it. test. If it is taken out and tested separately, but the influence factors of the pump body on its daily work are ignored, the results obtained in this way will undoubtedly have errors. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a water pump assembly with good clamping stability, high detection accuracy, which can stably test the torque of the impeller inside the pump body, and can also test the air tightness of the pump body. Into a dyna...
