Abstract

The utility model relates to a pair of electric welding tongs, composed of an upper tongs body and a lower tongs body; the upper tong body is provided with a tabular tong mouth; the rear part of the lower tong body is provided with an arc half pipe-shaped wiring end and a base wing is respectively arranged on the two sides of the lower tong body; the base wings are fixed with handles; the lower boss of the upper tong body, which is provided with a hole is inserted in the groove of the lower tong body and is connected by a rotation shaft; a spring is arranged between the upper tong body and the lower tong body. The utility model has the advantages of good thermolysis, low temperature, firmly clamping for a welding rod, steady handles, simple manufacturing technique, beautiful appearance, etc.

Description

Electrode holders

The utility model relates to a kind of novel electrode holders.

Electrode holders are indispensable instruments of electric welding welding, are clamped welding rod and are imported into powerful electric current to welding rod by it.But there are many shortcomings in the electrode holders that use at present: at first be that heat radiation is bad, cause the handle temperature too high, influence welder's operation; Next is that jaw fixture block and caliper copper billet are fixed with screw, and after using for a long time, especially owing to the influence of high temperature, the absent-mindedness of jaw fixture block swings the welding rod that is held, and causes solder joint inaccurate; In addition, wire input end resistance is big, easily heating and galvanic corrosion, and the fixing of handle also owes firm.

The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of reasonable in design, can firm clamping welding rod, good heat dissipation effect, long-lived electrode holders.

For achieving the above object, basic scheme of the present utility model is: electrode holders are divided into upper clamp and lower clamp; The upper clamp disjunctor has the flat jaw, to replace the jaw fixture block; The rear portion of lower clamp is provided with arc halfpipe connection jaws and is provided with the basic wing in both sides, and this base wing is used for fixing with handle; Upper clamp lower cam position with holes is embedded in the groove hole of lower clamp and by rotating shaft and is connected; Also be provided with spring between the last lower clamp.

Below by drawings and Examples the utility model is described in detail.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is a upper clamp skeleton structure schematic diagram of the present utility model;

Fig. 3 is a lower clamp skeleton structure schematic diagram of the present utility model.

With reference to accompanying drawing, the utility model is made up of upper clamp (10), lower clamp (20), rotating shaft (30) and spring (40); Upper clamp (10) has the flat jaw (11) of disjunctor and is provided with the lower cam position (13) of axis hole (12); Lower clamp (20) is established the arc halfpipe connection jaws (21) and the basic wing (22) at the rear portion, be provided with groove hole (23) in the position corresponding to upper clamp lower cam position (13); The lower cam position of upper clamp (13) is embedded in the groove hole (23) of lower clamp and by rotating shaft (30) and connects; The rear portion of upper clamp (10) and lower clamp (20) is provided with spring (40).

The tong arm (14) of upper clamp (10) is made perpendicular flat, has both guaranteed the intensity that reaches enough, saves material and weight reduction again.In addition, upper clamp (10) the also intrinsic insulator of appearance (15).

The arc halfpipe connection jaws (21) of lower clamp (20) also is furnished with halfpipe line lid (25) and screw (26), and power clip covers between (25) at arc halfpipe connection jaws (21) and halfpipe line, and fixing with screw (26).This mode of connection wiring is firm, resistance is little.

The anterior inboard of lower clamp handle (27) is provided with locating slot (28), and the basic wing (22) of lower clamp embeds wherein.Handle is firm, difficult loosening like this.

In addition, the jaw (29) of lower clamp (20) is provided with band and twill.Help fixedly welding rod like this.

Owing to adopted above-mentioned innovative design, make the caliper good heat dissipation, temperature is low; Firm to the welding rod clamping, handle is also firm, and welding rod does not have dancing during welding operation, long service life.In addition, than existing product saving working hour, and profile is also attractive in appearance when production and processing for this product.
