Abstract

An electric welding clamp. The problems that the electric conductor of the existing electrode holder and the jaw are integrated, the electric conductor cannot be replaced after being worn, and the V-shaped groove on the electric conductor is poor in electric conduction easily are mainly solved. The method is characterized in that: the bottom of the upper clamp body (2) is connected with a copper pressing plate (3), the upper part of the lower clamp body (5) is connected with a copper electric conductor (4), and the upper surface of the electric conductor (4) is provided with a plurality of U-shaped grooves (8). The electric conductor of the electric welding pliers is provided with the U-shaped groove, so that the electric conductivity is better, the clamping is firmer, meanwhile, the pressing plate, the electric conductor and the pliers body are split, and the pressing plate and the electric conductor only need to be replaced after being worn, so that the waste is avoided.

Description

Electric welding pliers

Technical Field

The utility model relates to the field of machinary, an electrode holders specifically says so.

Background

The electrode holders are common special operation tools, in the current common electrode holders, the electric conductors and the jaws are integrated, the electric conductors are easy to wear after long-time use, and the electrode holders are scrapped integrally, so that waste is caused. Meanwhile, the electric conductor of the current electrode holders is provided with a V-shaped groove for firmly clamping the welding rod, and the V-shaped groove ensures that the contact area of the electric conductor and the welding rod is small, the clamping is not firm, and the condition of poor electric conduction is possibly generated.

SUMMERY OF THE UTILITY MODEL

In order to overcome current electrode holders electric conductor and keep silent as an organic whole and make behind the electric conductor wearing and tearing can't change, the V-arrangement groove on the electric conductor is easy bad not electrically conductive, the utility model provides an electrode holders opens on this electrode holders's the electric conductor has the U-shaped groove, makes electric conductivity better, and the centre gripping is more firm, and clamp plate and electric conductor and the pincers body are split type simultaneously, only need change after the wearing and tearing clamp plate and electric conductor can, avoid extravagant.

The technical scheme of the utility model is that: the electric welding tongs comprise an upper tong body and a lower tong body, wherein the bottom of the upper tong body is connected with a copper pressing plate, the upper part of the lower tong body is connected with a copper electric conductor, and the upper surface of the electric conductor is provided with a plurality of U-shaped grooves.

One end of the U-shaped groove is communicated with the edge of the electric conductor, and the other end of the U-shaped groove is closed.

The utility model discloses following beneficial effect has: by adopting the scheme, the upper clamp body and the pressure plate of the electrode holder are separated, and the lower clamp body and the electric conductor are separated, so that only the pressure plate and the electric conductor need to be replaced after the pressure plate or the electric conductor is worn, the whole electrode holder does not need to be scrapped, and waste is avoided. The surface of the electric conductor is provided with the U-shaped grooves with different specifications, welding rods with different specifications can be clamped, meanwhile, the contact area of the electric conductor and the welding rods is increased through the U-shaped grooves, the electric conductivity is better, and the clamping is firmer.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a top view of the electrical conductor.

In the figure, 1-a pressure plate fixing bolt, 2-an upper clamp body, 3-a pressure plate, 4-an electric conductor, 5-a lower clamp body, 6-a sheath, 7-an electric conductor fixing bolt and 8-a U-shaped groove.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and 2, the electrode holder comprises an upper holder body 2 and a lower holder body 5, wherein the upper holder body 2 is connected with the lower holder body 5 through a pin shaft. The bottom of the upper clamp body 2 is connected with a copper pressing plate 3, the bottom surface of the pressing plate 3 is a smooth plane, a bolt hole is formed in the pressing plate 3, a counter bore is formed in the upper clamp body 2, and the pressing plate 3 is fixed on the upper clamp body 2 through the bolt hole by a pressing plate fixing bolt 1. The detachable pressure plate can be replaced after being worn. The upper portion of the lower clamp body 5 is connected with a copper conductor 4, the contact surface of the lower clamp body 5 and the conductor 4 is a smooth plane, a long hole is formed in the lower clamp body 5, a boss matched with the long hole is arranged on the conductor 4 and is arranged in the long hole, a conductor fixing bolt 7 penetrates through the long hole and is screwed on the conductor 4, and a nut is located in a groove in the bottom of the lower clamp body 5. The upper surface of the electric conductor 4 is provided with a plurality of U-shaped grooves 8, the U-shaped grooves 8 are matched with the radian of the outer diameter of the corresponding welding rod, the contact area between the welding rod and the electric conductor is increased, the electric conductivity is better, and the clamping is firmer. In addition, the thickness and the shape of the conductor 4 can be set to different specifications, and meanwhile, the U-shaped groove 8 is also set to different specifications, so that welding rods with different diameters can be placed. The U-shaped groove 8 one end communicates with each other with electric conductor 4 edge, and the other end is sealed, can play spacing effect to the welding rod, and both ends all have the U-shaped groove around the electric conductor 4 surface to U-shaped groove 8 is radial distribution along electric conductor 4 surface, is convenient for like this the welding rod of centre gripping different angles, and when electric conductor one end wearing and tearing, loosens electric conductor fixing bolt 7 and rotates 180 degrees with electric conductor 4 again, can continue to use.

Claims

1. The utility model provides an electrode holder, includes the pincers body (2), the lower pincers body (5), its characterized in that: the bottom of the upper clamp body (2) is connected with a copper pressing plate (3), the upper part of the lower clamp body (5) is connected with a copper electric conductor (4), and the upper surface of the electric conductor (4) is provided with a plurality of U-shaped grooves (8).

2. Electrode holder according to claim 1, characterized in that: one end of the U-shaped groove (8) is communicated with the edge of the electric conductor (4), and the other end is closed.
