Special automatic welding equipment for hydraulic oil cylinder with high right-angle oil nozzle locating accuracy

The invention discloses special automatic welding equipment for a hydraulic oil cylinder with high right-angle oil nozzle locating accuracy and belongs to the technical field of hydraulic oil cylinder production. The special automatic welding equipment comprises a quick oil nozzle locating tool, wherein a right-angle reversing seat is connected to the lower end part of a pressing arm of the quick oil nozzle locating tool, a stepped hole is formed in the right-angle reversing seat, the axis of the stepped hole is vertical to the movement direction of the pressing arm, a straight rod penetrates into the stepped hole, the outside diameter of the straight rod is matched with a smaller hole diameter of the stepped hole, external threads matched with internal threads of a right-angle oil nozzle are distributed on the external surface of one end of the straight rod, a limiting lock sleeve is sleeved on the other end of the straight rod, a locking threaded hole is formed in the limiting lock sleeve and is communicated with a through hole of the limiting lock sleeve, and a bolt piece is screwed in the locking threaded hole. According to the special automatic welding equipment, the technical problem of the existing special automatic welding equipment for hydraulic oil cylinders that the right-angle oil nozzle welding efficiency is low is solved, and the special automatic welding equipment has the advantages of high right-angle oil nozzle locating accuracy and the like during specific use.
