The placement assembly is convenient and fast to use, and the test assembly is very simple and convenient to detect, improving the efficiency of crankshaft runout detection. Insert one end of the crankshaft of the detected crankshaft assembly into the corresponding tooling assembly. At this time, the floating tooling, combined with the buffer spring and the retaining sleeve, gives a buffer to the crankshaft assembly to avoid hard contact and bruising. Then insert the connecting rod end of the crankshaft assembly into the connecting rod positioning fork. Then, the servo electric cylinder lifting column makes the bottom mounting plate slide on the guide rail around the sliding seat. The bottom mounting plate makes the mounting sleeve drive the rotating shaft upward through the stabilizing sleeve.

One end of the crankshaft assembly abuts against the positioning plate for positioning during the crankshaft runout measurement. Then, the tooling plate is placed on the workbench. The pneumatic slide of the test assembly enables the installation slide to drive the digital control dial indicator through the installation rod to detect both shaft ends of the crankshaft assembly and perform runout detection on it. The runout detection makes the fixture into a complete placement assembly. The placement assembly is convenient and fast to use, and the test assembly is very simple and convenient to detect, improving the efficiency of crankshaft runout detection.

[0015] In the present invention, one end of the crankshaft of the detected crankshaft assembly is inserted into the corresponding tooling assembly. At this time, the floating tooling, combined with the buffer spring and the retaining sleeve, gives a buffer to the crankshaft assembly to avoid hard contact and bruising. Then, the connecting rod end of the crankshaft assembly is inserted into the connecting rod positioning fork. After that, the servo electric cylinder lifting column makes the bottom mounting plate slide on the guide rail around the sliding seat. The bottom mounting plate makes the mounting sleeve drive the rotating shaft upward through the stabilizing sleeve.
