Description

Hollow Shaft Runout Length Gauge

technical field

The invention relates to a detection device, in particular to a beating test tool for a hollow shaft rod of an automobile front drive shaft. the

Background technique

The hollow shaft is the main component of the front drive shaft of the car. The precision requirements for the hollow shaft of the front drive shaft of the car are relatively high. The runout length of the hollow shaft is usually tested after the production and processing are completed. However, the current measuring tool for the run-out length of the shaft rod has a complex structure, is inconvenient to operate, and the accuracy of the test is not high. the
