Abstract

The utility model relates to a pair of durable electrode holders, which belongs to a metal welding tool and comprises a welding clamp core and an insulating casing. The utility model is mainly characterized in that the welding clamp core is composed of a large clamping plate, a small clamping plate which is arranged on the front upper part of the large clamping plate and a junction box which is used for clamping cables and is arranged on the rear end of the large clamping plate; a bolt hole is respectively arranged on the large clamping plate and the small clamping plate; a large clamping casing is butted with a small clamping casing through the bolt holes on the large clamping plate and the small clamping plate, which are that a cylinder casing passes through the bolt holes by a screw bolt of a clamping plate and a screw bolt of a casing; the front end of a welding clamp core formed by the butt welding of the large and small clamping plates is provided with a jack of a welding rod. The utility model has the advantages of small size, light weight, convenient replacement for welding rods and scald-proof performance for a handle; the utility model is suitable for different electric arc welding.

Description

Durable electrode holder

The utility model belongs to the metal solder apparatus, is specifically related to a kind of manual electric arc welding weld clip.

At present, widely used electrode holders external form is like scissors, the front portion is a duckbill metal clamp, the shell of clamp and handle are insulating materials, and it is connected as a single entity with threaded jackscrew, bit is made by copper material, its cable connector generally is fixed in the handle, and fastening with jackscrew, in this electrode holders welding process, the connector lug place is owing to adopt jackscrew fastening, can produce contact resistance after the energising, make hadle produce heat, operator's length service time can feel hot, and jaw easily produces spark phenomenon, and service life is short.Because handle is short and small, the loading and unloading welding rod is also required great effort in addition.

For addressing the above problem; Chinese patent 92239716.3 discloses a kind of straight folder formula electrode holders; the shell of this electrode holders is to consist of the yi word pattern structure by protective casing and handle two parts; enclosure has clamp and little spring; it is big that this electrode holders have overcome clamp-type electrode holders volume, and the jaw surface is the problem of oxidation easily, but because it has adopted rifle formula plate machine compression spring structure; and fin is arranged on the contact rod, make complex structure.

It is little that the purpose of this utility model provides a kind of volume, in light weight, and the welding rod clamping is firm, the durable easily electrode holder of replacing welding rod.

The purpose of this utility model also is to provide a kind of durable electrode holder, and it simple in structure uses hadle not generate heat long service life for a long time.

The utility model is to realize like this, it includes weld clip core and insulation crust, it is characterized in that described weld clip core is made up of big clamp plate 1, the terminal box 3 that is arranged on the plintlet 2 of big clamp plate 1 front upper part and is loaded on big clamp plate 1 rear end clamping cables, on big plintlet 1,2, have bolt hole, folder shell 4, clip shell 5 and a tube shell 6 are docking together by the bolt hole that the clamping plate bolt 7 that has nut, shell bolt 9 pass on the big plintlet 1,2 greatly, and the front end that docks the weld clip core that forms at big plintlet 1,2 has welding rod socket 11.

The utility model has the advantages that,, make its volume little, in light weight, durable owing to adopt the bolt that has nut from inside to outside weld clip core and insulation crust to be connected into yi word pattern.In addition because welding rod adopts the folder formula of inserting, not only chucking power is big, and the welding rod that changes the outfit is convenient, another advantage of the present utility model is that cable is securely fixed on the terminal box of big clamp plate with nut bolt, make the electrode holder line contact resistance of connection jaws little, be not prone to small spark phenomenon, thereby reduced the generation of heat, even use the hadle can be not hot for a long time yet.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the cutaway view of the utility model structural representation.

Fig. 2 is the amplification view of the A-A of the utility model Fig. 1.

Fig. 3 is the amplification view of the B-B of the utility model Fig. 1.

With reference to Fig. 1.It includes weld clip core and insulation crust the utility model, it is characterized in that described weld clip core is by big clamp plate 1, the terminal box 3 that is arranged on the plintlet 2 of big clamp plate 1 front upper part and is loaded on big clamp plate 1 rear end clamping cables is formed, at big plintlet 1, have bolt hole on 2, big folder shell 4, a clip shell 5 and a tube shell 6 are by the clamping plate bolt 7 that has nut, shell bolt 9 passes big plintlet 1, bolt hole on 2 is docking together, make it to form an integral body simple in structure and firm, at big plintlet 1, the front end of the weld clip core that 2 butt joints form has welding rod socket 11 (see figure 2)s, makes the loading and unloading welding rod very convenient.

Another main points of the present utility model are to be provided with clamping plate spring 8 at the two ends of clamping plate bolt 7.Its objective is that to make welding rod socket 11 elasticity under the effect of spring better, guaranteeing the firm grip welding rod, and the welding rod that changes the outfit is convenient.

Another main points of the present utility model are that cable coupling box 3 is " ∏ " type (see figure 3), and with the bolt 10 that has nut it are fastened on the bolt hole of opening at big clamp plate 1 rear portion.Adopt this attached cable mode, hold out against mode with respect to screw, its cable clamps cable forces and increases, and contact resistance reduces, and is not prone to spark phenomenon, so use hadle not generate heat long service life for a long time.

The utility model volume is little, and is in light weight, simple in structure, is applicable to various manual welding duties.
