Abstract

The utility model discloses a ground wire clamp device for welding, which solves the problem that the weldment surface is easily struck and the current conduction is instable during the welding process. The ground wire clamp device comprises a conductor pad, a spring, a conductor body and a conductor sleeve, wherein the spring is arranged in the ground sleeve, a tapping portion of the tail part of the conductor body passes through the spring, the conductor sleeve and the conductor pad are fixed through a nut, and an end head of a ground wire is fixed at the tail part of the conductor body through a hexagon-head screw bolt. A ground wire clamp is mounted on the weldment through a hexagon-head screw bolt and a nut. The external of the tail part of the conductor body adopts an external thread structure, and the internal of the tail part of the conductor body adopts a drilling and tapping structure. The ground wire clamp device has the advantages of simple structure, easy manufacturing and installation, good electrical conductivity and excellent wear resistance, greatly reduces the spark phenomena, and ensures the smooth performance of the welding process.

Description

Welding property-line clamp device

Technical field

The utility model relates to a kind of welding property-line device.

Technical background

Ground wire is overlapped on the welded part body during welding of tradition weldment, and ground wire wounds the weldment surface because loose contact produces spark phenomenon easily in the welding process, and affects the electric current conduction in the welding process.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the shortcoming that the weldment surface is easily wounded in the welding process, guarantees that the electric current conduction is stable.

Technical solutions of the utility model are as follows:

Welding property-line clamp device, it comprises conductor pads 3, spring 6, wire body 7, wire sleeve 8; Spring 6 is installed in 8 li of wire sleeves, and spring 6 is partly passed in wire body 7 afterbody tapping, and wire sleeve 8 and conductor pads 3 are fixed by nut 5, and the ground wire termination is fixed on wire body 7 afterbodys by hexagon-headed bolt 4.The ground wire clamp device is installed in the weldment below of having bored the hole by hexagon-headed bolt 2 and nut 1.External thread structure is adopted in wire body 7 afterbodys outside, and boring, tapping structure are adopted in wire body 7 afterbodys the inside.

For guaranteeing that ground wire contacts with welded part well, the inner spring structure that adopts of this place ply-yarn drill tool device, the conduction demand that can adapt to the different size weldment, external thread structure is adopted in wire body 7 afterbodys outside, be convenient to regulate the extension elongation of wire body, boring, tapping structure are adopted in wire body 7 afterbodys the inside, are convenient to the connection of ground wire termination.

The utility model has reached following technique effect:

1, apparatus structure is simple, is easy to make, installs and regulates;

2, adopt the brass wire body to conduct electricity, electric conductivity is better, and high abrasion resistance;

3, the application of device contained spring structure increases its conductive contact area with the welded part body, has reduced greatly the generation of spark phenomenon, the carrying out smoothly of assurance welding process.
