Description
Technical field
The utility model relates to a kind of spot-welding equipment, specifically a kind of two-head spot-welder head.
Background technology
Traditional mash welder comprises upper and lower two electrodes, two electrode contacts produce electric arc and weld, but can only weld common equipment for traditional mash welder, when for some special installations, due to its device structure complexity, the local parts of equipment can hinder the placement of one of them electrode, therefore adopt the welding of common welder of upper and lower two electrode forms to be just difficult to meet welding requirements, therefore when electric welding machine carries out end face welding, the general mode that adopts bipolar electrode to weld, namely bi-motor head is in side Contact welding junction simultaneously, existing bipolar electrode mash welder, because structure arranges unreasonable, on the one hand in welding process, pressure in welding end surface is unbalanced, in addition on the one hand, two electrodes are difficult to regulate accurately, Control Welding Process is unreliable simultaneously, be difficult to ensure the reliability of welding.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of welding pressure equilibrium, and electrode regulating is accurate, the two-head spot-welder head that soldering reliability is high.
In order to solve the problems of the technologies described above, two-head spot-welder head of the present utility model, comprise two lifting covers that are arranged on holder, the middle part of two lifting covers is arranged on a connecting plate simultaneously, between the inner chamber bottom surface of connecting plate and holder, be mounted with back-moving spring, between connecting plate and mount pad, overlapping guiding by lifting also can be by driving pedal-driven, in holder, there are two connecting rods of vertical installation, connecting rod lower end is connected with electrode tip holder through the pilot hole of holder, connecting electrode on electrode tip holder, the stage casing of two connecting rods is fixedly connected with respectively briquetting, the end of briquetting extend in longitudinal guide groove of side of lifting cover and can move up and down along guide groove, in lifting cover, be provided with guide rod, guide rod regulates the position of guide rod by the regulating nut that is arranged on lifting and puts, the lower end of lifting cover arranges locating piece, between guide rod and locating piece, be provided with two sections of Compress Springs, the end of briquetting is between two sections of Compress Springs.
Described lifting cover outside is also installed with travel switch, is provided with triggering part on the sidewall of briquetting, and described triggering part is pressed on the trigger point of travel switch.
Described triggering part is an eccentric wheel, and eccentric eccentric rotary axle is connected on briquetting by securing member.
Adopt after above-mentioned structure, due to the briquetting arranging on connecting rod, the end of briquetting extend between the interior two sections of Compress Springs of opening of lifting cover, can and then adjust pretightning force by regulating nut thus, make the isostasy of electrode in welding end surface, the triggering part simultaneously arranging is pressed on the trigger point of travel switch, by adjusting the distance between 2 of eccentric wheels, carry out the trigger position fine adjustment of trigger point, in the time that leaving starting point, eccentric wheel can trigger travel switch output signal, device start welding, make thus its structure arrange rationally, meet the isostasy of electrode in welding end surface, can regulate accurately two electrodes again, Control Welding Process is reliable simultaneously, ensure the reliability of welding.
