Problems solved by technology

[0002] Steel wheels are generally welded by rims and spokes. Since the traditional automobile wheel girth welder has only one welding torch, the entire welding process needs to be rotated by the workpiece 360 ​​degrees, so that the temperature difference on the entire circumferential surface of the weld It is very large, causing the workpiece to be easily twisted and deformed, which not only affects the quality and yield of the finished product of the wheel, but also the welding efficiency of a single wheel is very low

Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention will be further described:

[0011] Such as figure 1 As shown, the automobile wheel girth welder in this embodiment includes a machine body 1, a workbench 2 inside the machine body, a rotatable workpiece clamping device 3 arranged on the workbench 2, and a welding torch 4, wherein the welding torch 4 has three (only two of which can be seen in the figure) are arranged on the workbench 2 around the workpiece at intervals of 120 degrees. In this embodiment, the rotatable workpiece clamping device 3 is a positioning plate, and positioning pins (not shown in the figure) are provided near the edge of the positioning plate, and a tire expansion 301 is provided at the center of the positioning plate. In this embodiment, a cylinder 5 is provided on the top of the machine body 1, and a pressure plate 6 and a chuck 7 are pivotally connected to the cylinder, wherein the chuck 7 is provided with an expansion cla...

Abstract

The invention discloses a circular seam welder for automobile wheels. The circular seam welder comprises a welder body, a workbench arranged in the welder body, a rotatable workpiece clamping device arranged on the workbench and at least two welding guns, wherein the welding guns are uniformly arranged on the workbench around workpieces. Because the at least two welding guns are arranged, the welding efficiency is greatly improved. In addition, due to the introduction of a workpiece compacting and swelling component, the deformation of the wheels in the welding process is also greatly reduced, and the welding effect is also remarkably improved.

Description

Technical field: [0001] The invention relates to a welding machine, in particular to an automobile wheel girth welding machine. Background technique: [0002] Steel wheels are generally welded by rims and spokes. Since the traditional automobile wheel girth welder has only one welding torch, the entire welding process needs to be rotated by the workpiece 360 ​​degrees, so that the temperature difference on the entire circumferential surface of the weld It is very large, causing the workpiece to be easily twisted and deformed, which not only affects the quality and yield of the finished product of the wheel, but also the welding efficiency of a single wheel is very low. Since the present invention is an automobile wheel girth welder, the workpiece mentioned in this application all refers to the semi-finished wheel, that is, the rim and spokes that have been placed but not yet welded together. This concept will not be repeated below. Invention content: [0003] The technica...
