Abstract

The invention provides an automobile steering system input shaft outer diameter automatic detection device. The automobile steering system input shaft outer diameter automatic detection device comprises a base. The base is provided with a measuring block. The measuring block is provided with a groove for placing an input shaft. Both of two sidewalls of the groove are provided with a first pneumatic nozzle hole, a second pneumatic nozzle hole and a third pneumatic nozzle hole which are arranged successively. When the input shaft is placed into the groove, the first pneumatic nozzle hole, the second pneumatic nozzle hole and the third pneumatic nozzle hole correspond to position of a first diameter portion, a second diameter portion and a third diameter portion separately, and the first pneumatic nozzle hole, the second pneumatic nozzle hole and the third pneumatic nozzle hole are connected with a pneumatic measuring apparatus separately. By adopting the input shaft outer diameter automatic detection device, the detection speed of the input shaft can be effectively improved, the labor intensity of testers can be reduced, the occurrence of errors can be prevented, and the detection accuracy of the input shaft can be effectively improved, so that the outgoing quality of the input shaft can be effectively improved.

Description

technical field [0001] The invention relates to an outer diameter detection device, in particular to a device for automatically detecting the outer diameter of an input shaft used in an automobile steering system. Background technique [0002] Automobile steering system mainly includes steering wheel, input shaft, torsion bar and power steering hydraulic system. The power steering valve of the power steering hydraulic system consists of a valve sleeve and a valve. Both the valve sleeve and the valve core are provided with oil holes. The oil holes at different positions on the valve sleeve and the valve core are connected to each other to form a closed oil circuit with different flow directions. . The steering wheel is connected to the torsion bar through the input shaft, and the other end of the torsion bar is connected to the spool. When the steering wheel is turned, the torque is transmitted to the torsion rod through the input shaft, and the torsion rod drives the valve...
