Abstract
This utility model discloses a water pump assembly and testing fixture, relating to the field of water pump testing. It includes a plate with a mounting base fixedly connected to its upper end. A fixing groove is formed at the upper end of the mounting base, and a fixing screw is rotatably connected inside the fixing groove. Both sides of the outer surface of the fixing screw are threaded with threaded components. Using this structure, when the clamping motor is started, the motor output shaft drives the fixing screw in the fixing groove to rotate synchronously. Because the threaded components on both sides of the outer surface of the fixing screw are threadedly connected to it, and because the threaded components are limited by the fixing groove and cannot rotate with the fixing screw, under the action of the threaded transmission, the threaded components on both sides move towards each other along the axis of the fixing screw. This causes the mounting plate and the moving assembly, which are fixed to the threaded components, to move closer synchronously, ultimately allowing the clamping seat inside the moving assembly to precisely fit against the outer wall of the water pump, thus achieving stable clamping of the water pump.
