Description

Spin welding device for non-circular parts

technical field

The utility model belongs to the field of mechanical processing and assembly, and relates to an equipment device for superimposed welding or assembly of non-circular sheet workpieces. To facilitate welding and welding operations.

Background technique

Welding processing is a processing method commonly used in mechanical processing and assembly, and it cannot be replaced by other processing methods. When the welding process is formulated, the convenience of welding operation should be given priority.

For the superposition welding of non-circular sheet workpieces, the method commonly used at present is: welding personnel use pliers to clamp multiple workpieces together for welding operations. The disadvantages of this method are mainly manifested in: the thin slice workpieces cannot be accurately positioned when superimposed; the non-circular workpieces cannot be rotated during circumferential welding, which is very inconvenient for welding operations. Therefore, it is of great engineering significance to develop a device that is convenient for fast clamping and positioning of non-circular thin workpieces during welding and welding.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings in the prior art, thereby providing a rotary welding device for non-circular workpieces that can realize fast clamping and positioning of non-circular sheet workpieces in the welding process and facilitate welding.

According to the technical solution provided by the utility model, the rotary welding device for non-circular workpieces includes: a rotating shaft, a rotary support, and a non-circular sheet workpiece holder, both of which pass through the front connecting block and the rear connecting block of the rigid coupling. The bolts are tightly connected together.

The said rotating bracket is installed on the front bearing seat and the rear bearing seat by the front and rear bearings through the rotating shaft, and the front bearing seat and the rear bearing seat are installed on the base by bolts, so as to realize the rotation of the welding workpiece device.

In the non-circular sheet workpiece holder, the non-circular sheet workpiece is set on the non-circular mandrel, and the threaded connection shaft is respectively connected with the non-circular mandrel and the locking threaded end cap through the threads at both ends, thereby realizing Positioning and locking of workpieces.

Compared with the prior art, the utility model has the advantages that:

The utility model has simple and reasonable structure. As long as the non-circular sheet workpiece is set on the non-circular mandrel, and then rotate and lock the threaded end cap, the positioning and clamping of the workpiece can be realized; the non-circular mandrel is connected through the front connecting block and the rear of the rigid coupling The block is fastened together with the rotating shaft of the rotating bracket, so that the rotation of non-circular workpieces can be realized. The whole device is easy to operate, convenient for the positioning and clamping of the workpiece, and convenient for realizing the rotary welding operation.
