Forked fixed type electric welding tongs

Technical Field

The utility model relates to an electric welding tongs field, in particular to divide fixed electric welding tongs of fork.

Background

The electrode holders are used as common tools for electric welding, and are mainly used for clamping an electrode to carry out electrode arc welding. Electrode holders are typically hand-held insulated devices used with electric arc welding machines to hold and manipulate and secure an electrical connection to a welding wire during manual arc welding. According to the relevant technical standards, the electrode holders have main technical indexes such as shell protection, electric shock protection, temperature rise value, welding spatter resistance, falling resistance and the like, however, in the using process of the electrode holders in the prior art, the electrode holders are generally like a vice and are used for clamping objects at the front ends of the electrode holders for welding, the temperature is high during welding, and the handles are often pressed, so that the handles are easily damaged, and when heavy welding rods are particularly clamped, unstable holding is easily caused, and the electric welding effect is influenced.

The prior art has application number CN201910423918, and the application name is: a pair of rotatable electric welding pliers capable of being clamped in a rotatable and extending mode is disclosed, and the rotatable electric welding pliers has the advantages of being stable in clamping, long in service life, capable of being bent and adjusted in angle, long in holding distance and capable of preventing injury. However, in practical applications, the application has a complex structure, is easy to regulate failure if used for a long time, and has high replacement cost.

Disclosure of Invention

1. The technical problem to be solved is as follows:

to the technical problem mentioned above, the utility model provides a divide fixed electrode holders of fork. This device adopts branching fixed knot to construct, need not the handle and presses, has improved and has used convenience and stability.

2. The technical scheme is as follows:

a split-fixed electrode holder comprises a handle part and a holder body part of an insulating bakelite rod, wherein the handle part is fixedly connected with the holder body part; the method is characterized in that: the clamp body part comprises a first clamp body and a second clamp body; the inner ends of the first clamp body and the second clamp body are fixedly connected with the inner end head of the handle part; the inner ends of the first clamp body and the second clamp body are fixedly connected; the first clamp body and the second clamp body are both strip-shaped, and welding rods can be clamped by the first clamp body and the second clamp body; the first clamp body is a bending plate with a cross section of 90 degrees; the cross section of the first clamp body relative to the position of the second clamp body is a concave part of a 90-degree bending plate; the cross section of the second clamp body opposite to the first clamp body is arc-shaped.

Furthermore, the first forceps body is bent towards the second forceps body at the part connected with the handle part, and the gap between the first forceps body and the second forceps body is gradually enlarged along the direction in which the first forceps body extends outwards from the handle.

Further, the cross section of the second clamp body is circular.

Further, the concave part of the 90-degree bent plate is arc-shaped.

Furthermore, the device also comprises a wrist protecting part and a splash-proof part; the wrist protecting part is an annular rubber skin which surrounds the connecting position of the handle part and the clamp body part; the rubber skin extends outwards to form a bowl-shaped splash-proof part; the splash-proof part is bent towards the clamp body part.

3. Has the advantages that:

(1) the utility model discloses a pincers body portion utilizes the clearance of change directly to fix the welding rod for adopting the pincers body portion of branching fixed structure, need not to use handle clamping structure, can improve the stability of centre gripping.

(2) The two clamp bodies of the electrode holder are replaceable structures, and when the service life of the two clamp bodies is prolonged and shortened, the extending parts of the clamp bodies can be cut off by a gas cutting method, so that the convenient replacement is realized, and the electrode holder is low in cost and has a better practical effect than the traditional electrode holder.

(3) The handle part of the electrode holder is an insulating bakelite rod, and the current carrying capacity of the electrode holder in welding is high by matching with the handle part.

In a word, this electrode holders simple structure, it is simple to change, long service life, and welded current bearing capacity is strong.
