Description

Technical Field

[0001] The present invention relates to the technical field of production of electric power iron accessories, and specifically to a rotary welding machine for the production of electric power iron accessories. Background Art

[0002] Electric power iron accessories are commonly known as components (accessories) used in the transmission and transformation of electric power lines. They are metal accessories produced according to the special requirements of users. Electric power iron accessories mainly include cross arms, clamps, suspension rods, joints, ladders, lightning rods, cable trays, etc. used in electric power lines. Among them, cable trays are mainly made by assembling and welding sheet metal parts that have been sheared and bent into shape. Welding equipment refers to the equipment required to implement the welding process. Welding equipment includes welding machines, welding process equipment, and welding auxiliary tools. The selection of welding equipment is an important part of formulating the welding process. Corresponding welding equipment is selected according to the material characteristics, structural characteristics, dimensions, precision requirements, and service conditions of the welded structure. For the same welded material, different welding equipment can be selected according to different welding environments.

[0003] Generally, the welding equipment for electric power iron accessories can often only perform welding operations on one type of electric power iron accessory. This is because the limiting structure of the welding machine equipment can often only give priority to limiting one of the planar or curved structures. This causes inconvenience in the actual processing process, as different welding equipment needs to be selectively used according to the different structures of the components to be welded. The applicable range of the existing welding equipment for electric power iron accessories has limitations. Summary of the Invention

[0004] The purpose of the present invention is to provide a rotary welding machine for the production of electric power iron accessories to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

The synchronous lifting mechanism is connected with multiple groups of fixed frames. A middle lifting part is fixedly installed in the middle of the fixed frame. The fixed frame is fixedly connected with a lifting part. The lifting part is connected with two groups of symmetrically arranged first hinge frames.

The second chain lifting part, the first chain lifting part, and the middle lifting part have the same structure. The second chain lifting part is hinged with a third hinge frame hinged with the middle lifting part. The fixed frame is fixedly connected with two groups of limiting bent frames. When the first chain lifting part and the second chain lifting part are both in contact with the limiting bent frames, the first chain lifting part, the second chain lifting part, and the middle lifting part are arranged in an arc. When the first chain lifting part and the second chain lifting part are both in contact with the fixed frame, the first chain lifting part, the second chain lifting part, and the middle lifting part are arranged in a straight line.

[0012] As a further improvement scheme of the present invention: the middle lifting part, the first chain lifting part, and the second chain lifting part all include an outer casing. Four groups of rollers are symmetrically arranged and rotatably connected to the outer casing. A second active telescopic frame is fixedly connected to the outer casing. A roller frame is fixedly connected to the moving end of the second active telescopic frame. A fourth motor is fixedly connected to the roller frame. A driving roller is fixedly connected to the output shaft of the fourth motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the component to be welded is plate-shaped or strip-shaped, the lifting part drives the first hinge frame to move towards the fixed frame, so that the first hinge frame drives the first chain lifting part to move towards the fixed frame. The first chain lifting part drives the second chain lifting part to move towards the fixed frame through the second hinge frame, so that both the first chain lifting part and the second chain lifting part are in contact with the fixed frame, and the first chain lifting part, the second chain lifting part, and the middle lifting part on the same fixed frame are arranged in a straight line, so that the deformation supporting structure is adapted to the shape of the plate-shaped or strip-shaped component. After the component is placed on a group of deformation supporting structures located at the lower part of the frame, the welding structure moves to perform welding operations on the component. When the surface of the component to be welded is provided with an arc surface, the lifting part drives the first hinge frame to move towards the limiting bending frame, so that the first hinge frame drives the first chain lifting part to move towards the limiting bending frame. The first chain lifting part drives the second chain lifting part to move towards the limiting bending frame through the second hinge frame, so that both the first chain lifting part and the second chain lifting part are in contact with the limiting bending frame, so that the first chain lifting part, the second chain lifting part, and the middle lifting part are arranged on an arc line, so that the first chain lifting part, the second chain lifting part, and the middle lifting part jointly support the component to be welded, thereby restricting the movement of the component to be welded. Then the welding structure moves to perform welding operations on the component to be welded. By adjusting the shape of the deformation supporting structure, the present invention makes the deformation supporting structure match the shape of the component to be welded, so as to provide limiting support and perform welding operations on different-shaped electric power iron accessories, and improve the application range of the present invention.
