The spot welding equipment adopts two sets of welding arms, and can adjust opposite positions of welding electrodes, reduce the welding travel, save the travel movement time and decrease the whole machine size; the spot welding equipment adopts the X-axle servo and the Y-axle servo to link with the welding tool for conveniently clamping the welding workpieces, and the welding positions are accurate; as the manual control is not needed in the welding process, the quality of every welding spot is accordant; and in conclusion, the spot welding equipment has the advantages of stable quality, high welding precision, high production efficiency and low cost.

Description

A kind of spot-welding equipment

Technical field

The present invention relates to a kind of resistance welding techniques field, be specifically related to a kind of spot-welding equipment.

Background technology

Existing mash welder is all fixed station, and single armed mash welder can only weld on same position, and welding diverse location needs travelling workpiece to realize, and so just makes under production efficiency, and production cost increases.

Summary of the invention

The object of the invention is to design a kind of multi-point welding being applicable to diverse location, the spot-welding equipment of self-feeding.

Solve the problems of the technologies described above the technical scheme of employing:

A kind of spot-welding equipment, comprise fuselage, cooling system, control system, guidance panel, regulating system and feed system, described regulating system: comprise the welding mechanism being symmetrically set in fuselage the right and left, described welding mechanism comprises weld assembly and lower weld assembly;

Described feed system: for carrying welding work pieces, between upper weld assembly and lower weld assembly, it comprises frock, drives frock along the X-axis servo of fuselage parallel direction and movement in vertical direction and Y-axis servo.

As optimization: described upper weld assembly comprises and being connected and horizontally disposed fixing weldering arm with positive pole, along the upper copper coin group that upper fixing weldering arm moves back and forth, is arranged at the upper welding electrode in copper coin group, in driving, welding electrode moves up and down upper cylinder; Described lower weld assembly comprises and being connected and horizontally disposed lower fixing weldering arm with negative pole, along the lower copper coin group that lower fixing weldering arm moves back and forth, is arranged at the lower welding pole in lower copper coin group, drives the lower cylinder that lower welding pole moves up and down.

As optimization: described upper cylinder is fixed by upper rail and fuselage, described lower cylinder is fixed by lower guideway and fuselage.

Beneficial effect of the present invention: the invention adopts two bond pads arms, and can adjust the relative position of welding electrode, is applicable to the welding work pieces of below 1000mm, reduces the stroke of welding, saves the time of stroke motion, reduces the size of complete machine; The invention adopts X, Y-axis servo interlock welding tooling, and facilitate the clamping of welding work pieces, welding position is accurate; Because welding process does not need Artificial Control, guarantee the uniform quality of each solder joint; In sum, the spot-welding equipment of the invention, steady quality, welding precision is high, and production efficiency is high, and cost reduces.

Detailed description of the invention

As shown in Figure 1,2 and 3: a kind of spot-welding equipment, comprise fuselage 1, cooling system 6, control system, guidance panel 4, regulating system and feed system, described regulating system comprises the welding mechanism being symmetrically set in fuselage 1 the right and left, and described welding mechanism comprises weld assembly and lower weld assembly; Described feed system is for carrying welding work pieces, and between upper weld assembly and lower weld assembly, it comprises frock 16, drives frock 16 along the X-axis servo 23 of fuselage 1 parallel direction and movement in vertical direction and Y-axis servo 24; Described upper weld assembly comprises and being connected and horizontally disposed fixing weldering arm 10 with positive pole 9, along the upper copper coin group 17 that upper fixing weldering arm 10 moves back and forth, is arranged at the upper welding electrode 5 in copper coin group 17, and in driving, welding electrode 5 moves up and down upper cylinder 7; Described lower weld assembly comprises and being connected and horizontally disposed lower fixing weldering arm 20 with negative pole 19, along the lower copper coin group 21 that lower fixing weldering arm 20 moves back and forth, is arranged at the lower welding pole 3 in lower copper coin group 21, drives the lower cylinder 2 that lower welding pole 3 moves up and down; Described upper cylinder 7 is fixed by upper rail 8 and fuselage 1, and described lower cylinder 2 is fixed by lower guideway 22 and fuselage 1.

Before work, first according to the needs of Product jointing, determine the position of welding electrode, then start shooting by touch screen 4 set the starting point of welding work pieces, the right the first point, second point ... .., the left side the first point, second point ..., set point welding condition, during work, welding work pieces is placed in frock 16, press switch, frock 16 arrives first position on the right of welding machine with welding work pieces, right side lower welding pole 3 rises under the effect of right side lower cylinder 2, on right side, welding electrode 5 declines under right side upper cylinder 7 acts on, welding work pieces clamps with welding electrode 5 on the right side declined by the right side lower welding pole 3 risen, the electric current of at this moment transformer output is through positive pole 9, upper fixing weldering arm 10, upper copper coin group 17, welding electrode 5 on right side, welding work pieces, right side lower welding pole 3, lower copper coin group 21, lower fixing weldering arm 20, negative pole 19 forms welding circuit, because the resistance of welding work pieces is larger, under the powerful function of current, metal melts instantaneously, welding, right side upper cylinder 7, right side lower cylinder 2 backhaul, complete the welding of first, welding work pieces is delivered to the second point of welding by welding tooling 16, until all solder joints on the right of welding work pieces complete, after the right of welding work pieces has been welded, left side upper cylinder 7, left side lower cylinder 2 have been started working, and repeat the action on the right, until all solder joints on the left side complete, welding tooling 16 return to origin position, takes out welding work pieces, complete a weld cycle, when right side upper cylinder 7, right side lower cylinder 2 work, left side upper cylinder 7, left side lower cylinder 2 do not work, and vice versa.
