The spring is sleeved on the surface of the vertical rod, and can be installed on the mounting ring by means of the spring. The test head is installed on the spring, thereby installing the test head.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a base, mounting frame, mounting mechanism, fixing mechanism, testing mechanism, and driving mechanism, first installs the crankshaft on the support frame. The mounting plate is then moved onto the crankshaft. A lead screw is rotated, and through a threaded connection, the lead screw moves the fixing plate, which then moves onto the support frame, thus fixing the crankshaft. Next, the driving mechanism is activated, causing the servo motor to rotate. The servo motor drives the gear to rotate, the gear to move the gear track, the gear track to move the vertical rod, and the vertical rod to move the test head. The test head then tests the crankshaft. A spring drives the test head to move backward. Through the cooperation of the gear and the spring, the test head reciprocates.
