Automatic tightening machine for OBJ (outer pull rod of steering gear)

Abstract

The invention discloses an automatic tightening machine for an OBJ (outer pull rod of steering gear), and belongs to the field of precise assembly equipment. The automatic tightening machine comprises a rack, a clamp mechanism, a right pull rod tightening mechanism, a left pull rod tightening mechanism, a touch screen control panel, a PLC electrical control box, a right nut tightening mechanism, a right pull rod righting mechanism, a left pull rod righting mechanism and a left nut tightening mechanism. The tightening torque can be automatically judged, manual participation is reduced, and the assembling efficiency and reliability are improved. A touch screen is adopted as a manual interface, so that the operation is simplified, the setting of operation data is more flexible, and the assembly requirements of different workpieces can be met. A servo motor is used as an OBJ advancing power source, and the action is accurate and rapid; and an electric tightening machine is used as a power source for tightening a small nut so that the tightening torque can be accurately controlled and monitored in real time, and the assembly process requirements are met. In the aspect of electrical control, a PLC and the touch screen are adopted for control, and the electric tightening machine, the servo motor and an air cylinder are adopted as power sources and are responsible for all operation instructions and implementation of the equipment.

Description

technical field [0001] OBJ (steering gear outer tie rod) automatic tightening machine effectively solves the automatic assembly problem of OBJ (steering gear outer tie rod). It belongs to the field of precision assembly equipment. Background technique [0002] At present, all OBJ (steering gear outer tie rod) tightening machines produced in China adopt manual tightening or semi-automatic tightening, which takes a long time to assemble and has low reliability, which cannot meet the requirements of automatic production. Based on this, we have developed an OBJ (steering gear outer tie rod) automatic tightening machine, which realizes the automatic assembly of the outer tie rod on the basis that the tightening torque meets the requirements, and realizes the automatic monitoring of the torque during the tightening process. It fills up this gap in the country. Contents of the invention [0003] The invention provides an OBJ (steering gear outer tie rod) automatic tightening ma...
