Abstract

The utility model discloses an electric welding clamp, comprising a clamp body and a clamp mouth; the clamp body comprises an upper clamp body and a lower clamp body; the upper clamp body is provided with a locking slot and one or more screw holes; the lower clamp body is provided with a wire guide slot; the clamp mouth comprises an upper clamp mouth and a lower clamp mouth; the upper clamp mouth is matched with the locking slot of the upper clamp body to form a hollow cavity; and the hollow cavity is communicated with the wire guide slot. The utility model simplifies the structure of the electric welding clamp, eliminates the original complex connection structure at a handle and saves the material; the cable is directly connected on the upper clamp body, so that the heating points are away from the handle to reduce the heating sources. The utility model has light weight and less heat and does not burn the hand; besides, the utility model which can be continuously used has low cost and can be easily accepted by the majority of manufacturers and users.

Description

A kind of electrode holders

Technical field

The utility model relates to a kind of arc-welding apparatus, the high electrode holders of particularly a kind of alterating and direct current welding efficiency.

Background technology

The variation of constantly updating of electrode holders of Xiao Shouing in the market, its face shaping impacting market, but substantial structure does not break through traditional design; Cable directly is connected with the red copper part of handle core rear end, pushes down the end of a thread by screw, and the copper spare of handle core is connected with lower clamp, and electric current arrives welding rod again by the handle core lower clamp of flowing through.The lower clamp rough surface, in use the surface easily forms compact oxide, from the handle to the welding rod, conductive phase is adjusted the distance longer, whole caliper all will generate heat in the use, and the heat on the handle is difficult for heat and sends out, constantly accumulation, use caliper heating of a specified duration more obvious more, usually can see that every use a period of time of user just has to quit work because scald one's hand, and directly causes the low of efficient, this traditional structure consumptive material, power consumption, heaviness, hot are brought inconvenience to the user.

Once also had and scalded one's hand, thermal insulation layer was set, and effectively stoped handle hot in the short time at the handle and the heating position of electrode holders in order to prevent, but the caliper structure is still comparatively complicated, thermal insulation layer can not effectively dispel the heat, and the aging of rubber parts such as cable handle quickened in heat alluvial.

The utility model content

Defectives such as the utility model is big for overcoming prior art handle heating in use, and it is untimely to dispel the heat provide a kind of electrode holders little, good heat dissipation that generate heat.

The technical scheme that the utility model solves existing issue is: a kind of electrode holders, comprise caliper, jaw, and its structure is that caliper comprises upper clamp and lower clamp, and upper clamp is provided with draw-in groove and one or more screw, and lower clamp is provided with metallic channel; Jaw comprises upper clamp nozzle and lower clamp nozzle, and upper clamp nozzle matches with the upper clamp draw-in groove and forms a cavity, and cavity communicates with metallic channel.

Upper clamp nozzle described in the utility model is provided with the breach that matches with the upper clamp draw-in groove.

Be provided with the screw that matches with it in the screw described in the utility model, screw is provided with spring shim.

The utility model compared with prior art, its beneficial effect is: simplified electrode holders mechanism, saved the lengthy and tedious wiring construction in handle place in the past, saved material, cable directly has been connected on upper clamp, heat generating spot away from handle, reduce pyrotoxin.The utility model is in light weight, heating less, non-scald on hand, can use continuously, cheap, easilier accepted by vast manufacturer and user.

The specific embodiment

Referring to Fig. 1-4, the implementation case comprises: caliper 1, jaw 2, protection body 3, caliper 1 comprise upper clamp 11 and lower clamp 12, and upper clamp 11 is provided with draw-in groove 13 and one or more screw 14, and lower clamp 12 is provided with metallic channel 15; Jaw 2 comprises upper clamp nozzle 21, and upper clamp nozzle 21 matches with upper clamp 11 draw-in grooves 13 and forms a cavity 4, and cavity 4 communicates with metallic channel 15; Protection body 3 is spirally connected with caliper 1, and in order to increase the dynamics that cooperates of upper clamp nozzle 21 and upper clamp 11, upper clamp nozzle 21 is provided with the breach 23 that matches with upper clamp 11 draw-in grooves 13.For the ease of wiring, be provided with the screw 16 that matches with it in the screw 14, screw 16 is provided with spring shim 17, after screw 16 compresses the end of a thread like this, is difficult for loosening.Last protection body 31 is provided with and the concentric through hole 33 of upper clamp 11 screws 14, easy disassembly screw.

Referring to Fig. 1 and 5, cable b passes handle c through metallic channel 15 in the present embodiment, and the end of a thread 6 pierces into cavity 4, tightens screw 16, compresses the end of a thread 6.In use heat generating spot has just had only upper clamp nozzle 21, owing to no longer need lower clamp 12 conduction, lower clamp 12 can no longer adopt relatively costly red copper, can adopt other light weights, relatively inexpensive material, such as cast iron, cast steel etc.

Claims
