汽车液力变矩器部件全自动凸焊生产线再利用及工艺

Reform and reuse and process of automatic projection welding product line of the torque converter assembly

介绍了全自动凸焊专用生产线,在充分吸收、消化和借鉴国外技术及结合国产液力变矩器结构特点基础上,成功实现了该生产线的改造和再利用,弥补了顶盖定位柱焊接存在的工艺水平落后、焊接质量不稳定、生产效率低、制造成本高等诸多不足。其成功经验,有助于国产液力变矩器自动化焊接工艺水平的提高和发展,具有较高的参考价值和经济价值。

A special production line of automatic projection welding is introduced in this paper. The reform and reuse of this production line is realized successfully, based upon the relevant foreign technology and the structur- al characteristic of domestic torque converter, advanced the process technical level, welding quality, and pro- duction efficiency of the projection welding of pilot hub of the torque converter cover. It is found high practical value and economic value from the improvement and development of the traditional process technique of domestic torque converter by this successful experience.
