AI Technical Summary

Problems solved by technology

Since the welding is manually operated, it is very random and it is difficult to control the pressure
If the pressure of the electrode is too small, there will be poor contact between the electrode tip and the workpiece, causing arc explosion, burning the workpiece and damaging the electrode tip; there will also be false welding between the workpieces
If the pressure of the electrode is too high, the force on one side will cause a convex hull on the other side of the part, which will affect the appearance of the workpiece

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0012] Such as figure 1 As shown, the present invention is composed of an electrode core 1, an electrode head 2, a micro switch 3, a guide sleeve 4, a tightening screw 5, a pressure adjustment nut 6, a spring 7, a switch box 8 and a handle 9, wherein the electrode core 1 is A two-stage stepped cylindrical structure with a large top and a small bottom. The large stage of the electrode core 1 is located in the guide sleeve 4, and the two are matched with each other. The small stage of the electrode core 1 is downward from the bottom of the guide sleeve 4. Pass out, and the step surface between the large and small sections of the electrode core 1 is limited by the inner flange at the bottom of the guide sleeve 4 . The electrode head 2 is mounted on the bottom of the electrode core 1, and the axis of the electrode head 2 and the axis of the electrode core 1 are ...

Abstract

The invention discloses an adaptive single-side welding torch, which is characterized in that the large step section of an electrode core is arranged in a pilot sleeve, and the small step section of the electrode core passes through the bottom of the pilot sleeve; the top of the electrode core is provided with a puller bolt, the upper end of the puller bolt passes through a pressure regulation nut, and the pressure regulation nut is nested in the top of the pilot sleeve; a switch box is arranged beside the pilot sleeve, a microswitch is arranged in the switch box, a button of the microswitch passes through a through hole on the pilot sleeve and extends into a notch arranged at the electrode core. Through forming an adaptive structure by the components such as the electrode core, the pilot sleeve, the puller bolt, the pressure regulation nut and a spring, etc., the adaptive single-side welding torch provided by the invention can guarantee that the pressure of each welding is basically same, and ensure the welding quality and the appearances of workpieces; meanwhile, the welding torch has the characteristics of being simple in operation and convenient in adjustment, and having reliability and flexibility, and greatly improves the welding efficiency.

Description

technical field [0001] The invention relates to a welding tool, in particular to an adaptive single-sided welding torch. Background technique [0002] Welding gun is an important tool for processing and manufacturing enterprises to perform single-sided welding operations. At present, a general-purpose single-sided welding torch is composed of an electrode head and a micro switch. The electrode head is connected to the main cable, and the electrode head is equipped with a micro switch for controlling welding. The micro switch is connected to the welding control line. When welding, the operator first needs to align the electrode tip to the welding position, then control the pressure between the electrode tip and the welding steel plate, and then press the micro switch to proceed. Because it is single-sided welding, only one side of the steel plate is stressed at the position of the solder joint, and the magnitude of the force directly affects the welding quality and appearanc...
