Problems solved by technology

[0003] In the prior art, most of the welding machines that use touch welding to work use manual control of the pressurization, preheating and other links in the welding process, which not only wastes a lot of manpower, increases production costs, and the quality of the products produced is even worse. get a unified guarantee
In addition, most of the existing butt welding machines can only weld one workpiece to be processed, and can only weld different welding parts of the same workpiece to be processed bit by bit. For products that need to weld multiple workpieces or For workpieces that need to be welded in multiple parts, the position and angle of the workpiece can only be changed manually, which makes this kind of welding machine with a low degree of automation inconvenient to use and low in welding efficiency

Embodiment 1

[0034] Such as figure 1 As shown, the automatic welding machine disclosed in this embodiment includes a workbench 1, a welding mechanism arranged on the workbench and a control system for controlling the welding mechanism. The welding mechanism includes a central electrode and three moving parts arranged around the central electrode. Electrode 2, the movable electrode includes a slide rail, a movable electrode block slidably installed on the slide rail, and a movable electrode cylinder 3 for driving the electrode block to slide. system connection.

[0035] During implementation, the workpiece to be processed is socketed on the central electrode, and the control system controls the movable electrode to contact the workpiece to be processed. After the central electrode and the movable electrode are respectively connected to the two poles of the power supply, welding can be realized. One or more workpieces can be fixed on the central electrode, and one or more workpieces can als...

Embodiment 2

[0046] Compared with the automatic welding machine disclosed in Embodiment 1, the automatic welding machine disclosed in this embodiment differs in that in this embodiment, two welding mechanisms are provided on the workbench, and each welding mechanism includes four movable electrode.

[0047] In addition, in this embodiment, a pressing mechanism for positioning and fixing during welding is provided above the center electrode. This is because for workpieces with complex shapes on the central electrode block or movable electrode block, it is necessary to use a pressurizing mechanism to pressurize it from above the central electrode during pressurization to realize positioning and fixing.

[0048] The pressurizing mechanism in this embodiment includes a mounting frame fixed on the workbench, a pressurizing cylinder arranged on the mounting frame, and a pressing plate arranged on the push rod of the pressurizing cylinder, and the pressing plate is opposite to the central electro...

Abstract

The invention relates to an automatic welding machine. The automatic welding machine comprises a working platform, one or more welding mechanisms arranged on the working platform and a control system for controlling the welding mechanisms. The automatic welding machine is characterized in that the welding mechanism comprises a central electrode and a plurality of moving electrodes arranged at the periphery of the central electrode, wherein each moving electrode comprises a sliding rail, a moving electrode block and a moving electrode cylinder; the moving electrode block can be arranged on the sliding rail in a sliding manner; the moving electrode cylinder is used for driving the electrode block to slide upwards; the central electrode and the moving electrodes are respectively connected with two electrodes of a power supply; and the moving electrode cylinder is connected with the control system. The automatic welding machine has the advantages that a plurality of workpieces or a plurality of welding parts of the same workpiece can be welded automatically and simultaneously, the automation degree is high, the use is convenient and the welding efficiency is high.

Description

technical field [0001] The invention relates to electric welding equipment, in particular to an automatic welding machine. Background technique [0002] Butt welding is also called resistance welding. It has the characteristics of high production efficiency, low cost, and material saving. It is widely used in industrial production. It is to apply pressure through electrodes after combining weldments, and use current to pass through the contact surface of the welding head and adjacent areas. A welding method in which resistance heat is generated for welding. [0003] In the prior art, most of the welding machines that use touch welding to work use manual control of the pressurization, preheating and other links in the welding process, which not only wastes a lot of manpower, increases production costs, and the quality of the products produced is even worse. Get a unified guarantee. In addition, most of the existing butt welding machines can only weld one workpiece to be pro...
