The bottom of the clamp body 1 is connected with the adapting bottom plate 8 through bolts.
The base plate 8 is assembled and connected with the vibration bench 9.
According to the requirements of the test specification, if the electronic shaft is required to be locked in the test process, the motor shaft locking block 6 is firstly installed in the groove 3 through the screw hole. Otherwise, the motor shaft locking block 6 is not required to be installed. In the present embodiment, the motor shaft lock block 6 is required to be installed by default.
Then, a test sample of the steering power-assisted motor 7 is installed in the groove 3 through a screw hole, and the motor shaft is locked and connected with the gear structure of the motor shaft locking block 6 in a matching way while the steering power-assisted motor 7 is fixed. Forming a combination as shown in fig. 4.
After the test sample is installed, the first combination is assembled with the adapter bottom plate 8 through a screw hole at the bottom of the clamp body 1 to form a second combination, as shown in fig. 5 and 6.
