一种70 T钩尾销挡板焊接定位装置的设计

Design of a 70T Coupler Tail Pin Baffle Welding Positioning Device

首先对70 T钩尾销挡板焊接作业现状进行调查分析,发现钩尾销挡板焊修作业,需要两名作业人员来共同完成,由一人托举挡板,另一人进行焊修,存在不安全、定位不准、工作效率低等问题。针对问题,设计出通过压缩风缸支撑的移动式焊接定位装置,主要由定位装置、升降装置、控制装置和走形装置组成。然后对方案进行实施,投入现场使用,最后对工装的效益及推广效果进行了阐述。对具有相同70 T钩尾销焊修作业难题处理提供了思路,可推广应用到全国货车车辆段使用。

First of all,through the investigation and analysis of the current situation of the welding operation of 70T coupler tail pin baffle,it is found that the welding operation of coupler tail pin baffle needs two operators to complete together,one person lifts the baffle,and the other person carries out welding repair,which has the problems of insecurity,inaccurate positioning and low working efficiency.In view of the problem,a mobile welding positioning device supported by compressed air cylinder is designed,which is mainly composed of positioning device,lifting device,control device and walking device.Then the scheme is implemented and put into field use.Finally,the benefit and promotion effect of the tooling are described.This paper provides a solution to the problem of welding repair of the same 70 T coupler tail pin,which can be applied to the national freight car depot.
