Problems solved by technology
At present, the positioning welding of this part is completely done manually. First, fix the two parts on the fixture, and perform gas shielded welding to fix the position of the hexagon and the piston pin. This operation has the following problems: 1. The size and position of the solder joints are very small. It is difficult to be consistent, the welding strength is difficult to control, and the reliability of positioning cannot be guaranteed; 2. The spatter will damage the surface of the workpiece during welding, causing the workpiece to be scrapped; 3. The operation is troublesome and inefficient. One operator can only position 300 pieces a day. about

Abstract
The invention discloses a hexagonal shaft positioning welding machine, which is used for realizing positioning welding of a hexagonal body and a piston pin of a hexagonal shaft. The hexagonal shaft positioning welding machine comprises a fixture, a rotation device, a support, a welding machine and a push mechanism, wherein the fixture is used for clamping the hexagonal shaft; the rotation device is fixedly arranged below the fixture and is used for supporting and driving the fixture to rotate; the support is used for supporting the rotation device; a welding pistol of the welding machine is fixedly arranged on the support and corresponds to a welding part of the hexagonal shaft; and the push mechanism is arranged on the support and is used for pushing the hexagonal shaft of which positioning welding is completed out of the fixture. In the hexagonal shaft positioning welding machine, the fixture is quick to clamp, positioning is accurate, and required form and position tolerance is ensured; the push mechanism can quickly push the welded hexagonal shaft out of the fixture, and other tools are unnecessarily adopted to take the hexagonal shaft out of a die by manual; the technical requirement of an operator is reduced, and meanwhile, the labor intensity is reduced; a movable protection plate is also arranged on the support, and the harm of welding slag splashing or sparking to the operator during operation can be prevented; and positioning and welding efficiency are greatly improved.
Description
technical field [0001] The invention relates to a welding machine, in particular to a hexagonal shaft positioning welding machine. Background technique [0002] The hexagonal shaft is an important auto part with high technical requirements. The part is welded by the hexagonal body and the piston pin. At present, the positioning welding of this part is completely done manually. First, fix the two parts on the fixture, and perform gas shielded welding to fix the position of the hexagon and the piston pin. This operation has the following problems: 1. The size and position of the solder joints are very small. It is difficult to be consistent, the welding strength is difficult to control, and the reliability of positioning cannot be guaranteed; 2. The spatter will damage the surface of the workpiece during welding, causing the workpiece to be scrapped; 3. The operation is troublesome and inefficient. One operator can only position 300 pieces a day. about. Contents of the inve...
