Abstract

The utility model discloses a skid-proof electric welding pincer, whose jaw is designed into a combined right angle type; one side of the welding pincer is provided with a right-angle baffle plate which can prevent the welding rod skidding in the welding pincer and can also transmit electricity through the cylindrical surface of the welding rod head. So the contact resistance of the welding pincer is very small and the welding pincer doesn't strike a spark, which can extend the service life of the welding pincer.

Description

Skid-proof electric welding pincers

The present invention relates to a kind of electrode holders, is solder set.

The main effect of electrode holders is to allow the soldering turret of big electric current by hand-guided be transferred to go in the welding rod to weld.Therefore require electrode holders tightly to clamp welding rod, can not slide.

But because the workpiece of welding has rusty stain and oxide layer, and striking resistance is bigger, in order to reduce contact resistance, the welder always will be along the axial direction and the workpiece collision of welding rod when striking for the welder.And electrode holders to clamp the position of welding rod be circular and very smooth.Therefore, welding rod skids in electrode holders easily, produces electric spark, analyzes from the reason that present soldering turret burns out, and great majority all are because welding rod skids and causes.

Purpose of the present invention provides a kind of electrode holders, and it can prevent that not only welding rod from skidding in soldering turret, can also improve power transmission mode simultaneously.

Invention is achieved in that as long as the jaw of soldering turret is designed to right-angle type, promptly vertically above the either side jaw of soldering turret just can block the slip of welding rod by putting a right-angle baffle.This piece right-angle baffle can with the jaw cast solid, also can make movable.

The concrete structure of invention is provided by following embodiment and accompanying drawing.

Fig. 1. be the overall diagram of the anti-skidding electrode holders of proposition according to the present invention.

Fig. 2. be the jaw A-A profile of anti-skidding electrode holders.

Digitized representation among Fig. 2:

1. right jaw 4. left jaws

2. right-angle baffle 5. gives and establishes screw

3. brass screw

Can see clearly that from accompanying drawing 2 if welding rod is placed between right jaw (1) and the left jaw (4), the tail end of welding rod is necessarily blocked by right-angle baffle (2) so.The brass screw (3) of outwarding winding, right-angle baffle are promptly detachable, are contained in giving of left jaw (4) and establish in the screw, and this is in order to adapt to the custom of some welder's reverse grip electrode holders.The material of right-angle baffle (2) is identical with the material of left and right jaw, all is by copper.Therefore, when welding, welding current conducts to the welding rod except the left and right jaw by soldering turret, can also conduct electricity by the round section of right-angle baffle contact electrode tail end.Make that contact resistance significantly reduces between soldering turret and the welding rod, lower the heating of soldering turret jaw greatly.

Because skid-proof electric welding pincers can prevent welding rod and slide, and eliminates the phenomenon that soldering turret sparkles, and can reduce the contact resistance caloric value again, so significantly improved the service life of soldering turret.

Claims (1)

1. A kind of electrode holders is characterized in that jaw one side of soldering turret is equipped with right-angle baffle [1], and right-angle baffle [1] can be made of one with the electric welding jaw, also can be movable.When movable, as long as knockout screw [2] just can install to right-angle baffle one side of reverse side.
