Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] refer to figure 1 , the present invention provides a hand-held welding tongs device, which is suitable for holding and applying force to carry out welding operations. For welding precision and small workpieces, the hand-held welding tongs device can be made into a smaller size, so that it can be operated with one hand, and the electrode rod can be flexibly extended into the welding spot to be welded, and then the device is held tightly, using the pressure The elastic force of the tight spring realizes the clamping of the two electrode rods, ensuring the stability of the pressure during the welding process. For welding of fixed, immovable large workpieces, such as workpiece welding in the field of automobile manufacturing, the hand-held welding tongs device can be made into a larger size, which can be operated with two hands, or the hand...

Abstract

The invention relates to a handheld soldering tong device which comprises a mounting housing, a first tong body, a second tong body, a cover body, a compression spring and a limiting mechanism, wherein the first tong body is assembled at the bottom of the mounting housing, and a first electrode bar is arranged on the end part of the first tong body; the second ton body is rotatably assembled on the mounting housing, and a second electrode bar corresponding to the first electrode bar is arranged on the end part of the second tong body; the cover body is rotatably assembled on the top of the mounting housing; the compression spring is supported between the cover body and the second tong body; and the limiting mechanism is supported between the cover body and the first tong body, and the cover body is braced by the limiting mechanism to limit rotation of the cover body. Pressures of the first and second electrode bars clamping a to-be-welded part are fully frame an elastic force generatedby the compression spring, and the to-be-welded part can be kept stably in a welding process, so that the stability of the pressure is guaranteed. Meanwhile, the contact resistance is further kept unchanged. Under a circumstance of a stable power supply, it can be ensured that the welding effect is consistent, so that the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a handheld welding tongs device. Background technique [0002] Welding tongs are tools for welding, and hand-held welding tongs are tools for welding through the grip of human hands. When the existing hand-held welding tongs are welding, the force is exerted on the body of the welding tongs through the grip force of the human hand, so that the two electrode rods clamp the workpiece to be welded, and then the electrode rods are connected to the power supply to realize welding. The pressure of the workpiece to be welded comes from the grip strength of the human hand. If the grip strength is greater, the pressure of the electrode rod pressing the workpiece to be welded will be greater. Correspondingly, the contact resistance between the electrode rod and the workpiece will be smaller, and the current Under the same conditions, the heat generated at the welding point becom...
