转向助力器扭杆自动压拔校直设备研制

The Design of Automatic Press-in and Straightening Machine for Electronic Power Steering Torsion Bar

根据转向助力器扭杆压拔校直工艺的要求,研制出一种自动压拔校直设备,采用专用夹具提高系统精度,克服了传统工艺工效低、装配精度低等缺点。该设备在自动压拔校直时,以PLC为控制系统核心,与HMI协调作用,可修改、设置相关参数,确保扭杆压拔、校直的效率及合格率。

The automatic press-in and straightening machine was designed according to the processing requirements of electronic power steering torsion bar. The system＇s machining accuracy was increased by using private fixture, overcoming the shortcomings of old process such as low efficiency and low assembly accuracy. PLC was the system＇s centre controller, working together with HMI. Related parameters could be modified through HMI. So the system accuracy and the percent of pass can be assured.
