Cylinder part welding method and cylinder part welding device

Abstract

Discloses is a cylinder part welding method and a cylinder part welding device. The welding device is operated by the method and comprises a frame (1), a power drive unit (2) connected with the frame (1), a chuck (3) connected with the drive unit (2), a tail clamping mechanism slidably connected with a guide rail of the frame (1), at least one welding gun support (18) and at least one automatic welding gun (19) capable of being movably connected with the welding gun supports (18). The method includes that a cylinder part to be welded is fed between the chuck (3) of the welding device and the tail clamping mechanism and extruded to be fixed by rotating the chuck (3); the automatic welding guns (19) align to the portions to be welded; the power drive unit (2) and the automatic welding guns (19) are started for welding while rotating; the power drive unit (2) and the automatic welding guns (19) stop operating after welding is completed, the chuck (3) is unscrewed, a handle (5) of the tail clamping mechanism is rotated to enable the tail clamping mechanism to release from the cylinder part, and then the part is taken out.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing of a plurality of cylindrical parts welded into a workpiece, in particular to a welding method and device for welding a plurality of cylindrical parts into a workpiece after being axially connected. Background technique [0002] Since the welding of circular workpieces is mostly manual welding, two people are generally required to cooperate with the operation. First, the two workpieces are connected by spot welding, and then the welding process is performed. This manual welding process cannot ensure verticality and parallelism. Correct, it is easy to cause uneven welds during welding, which is very unsightly; the welds of the two workpieces will be greatly deformed due to manual welding during welding, and it is difficult for the product to meet the standard size requirements; in addition, manual matching It is impossible to achieve one-shot welding in place during welding, an...

Problems solved by technology

The technical solution provided by this utility model is inconvenient in terms of workpiece clamping, has low flexibility, and it is difficult to weld cylindrical parts composed of more than three parts at the same time

From the drawings, the clamping device of the device uses a thimble, and there is relative motion between the thimble and the parts to be welded. On the one hand, due to the relative motion during the welding process, the rotation speed of the parts to be welded may fluctuate, thus affecting the welding process. quality; on the other hand, the contact area with the end of the part to be welded is small when fixed, and the stability when fixed is poor for parts with large mass
