Problems solved by technology
In the actual production process, each welding needs to manually lock the three-jaw chuck, which takes too long to process and the production efficiency is not high; and the diameter and length of the pin shaft have various specifications, and the positioning of the workpiece is not accurate. The machining accuracy is low. Since the main body of the pin shaft needs to be inserted into the chuck during welding, the pin plate and the end face of the chuck are close to each other. For longer and heavier pin shafts, manual loading and removal are more laborious.

The invention discloses an automatic workpiece girth-welding device and method. By the adoption of the automatic workpiece girth-welding device and method, fully-automatic girth welding of a workpiece can be achieved, welding technology is simple, welding efficiency is high, and the structure is simple and reasonable. The device comprises a soldering set table arranged on a machine body, a corresponding workpiece table arranged on the machine body, and a corresponding numerical control system, wherein the soldering set table comprises a soldering set sliding execution device, the workpiece table comprises a feeding movement device corresponding to the soldering set sliding execution device, and the feeding movement device comprises a rotary feeding device and a corresponding lifting supporting mechanism. According to the method, clamping and girth welding are achieved by means of interaction of the dead weight of a workpiece and friction force formed between the wall of the corresponding portion on the upper portion of the workpiece and the upper end face of a workpiece sleeve and the upper end face of a transition sleeve disc.
Description
technical field [0001] The invention relates to a manufacturing device for construction machinery parts. In particular, it relates to an automatic workpiece ring welding device and a ring welding method thereof. Background technique [0002] The existing girth welding including the pin shaft used in construction machinery is to first fix the pin shaft and the pin plate by spot welding, and then place the spot-welded pin shaft in the three-jaw chuck of the girth welding machine to fix it. Rotation of the chuck for girth welding. In the actual production process, each welding needs to manually lock the three-jaw chuck, which takes too long to process and the production efficiency is not high; and the diameter and length of the pin shaft have various specifications, and the positioning of the workpiece is not accurate. The processing accuracy is low, because the main body of the pin shaft needs to be inserted into the chuck during welding, and the pin plate and the end face o...
