Welding and fixing device of automobile coil rack

The invention provides a welding and fixing device of an automobile coil rack. A rotary disc driven by an internal worm and gear is arranged above a worm and gear drive box doubling as a base. An oil cylinder corresponding to the rotary disc is mounted at the top of one side of the worm and gear drive box through a support. A press wheel is arranged at the end of a telescopic piston rod of the oil cylinder. The press wheel can abut against a barrel and a flange fixed by a chuck in the middle of the rotary disc so as to facilitate welding. During use, the flange of the coil rack can be fixed through the chuck, the end of the oil cylinder abuts against the barrel so that the barrel and the flange can be engaged stably, and the barrel and the flange can be welded while overall rotating up and down. 本发明提供种汽车线圈架焊接固定装置，兼作底座的涡轮涡杆传动箱上方设有通过内置涡轮涡杆传动的转盘，在涡轮涡杆传动箱侧通过支架在顶部装有与转盘对应设置的油缸，在油缸的伸缩活塞杆端头设有压轮，该压轮可顶压筒体与转盘中间卡盘所固定的法兰方便焊接。使用时，可通过卡盘将线圈架的法兰固定，再通过油缸端头将筒体顶压与法兰吻合稳定，即可边上下整体旋转边将两者焊接。
