Description
Technical field
The present invention relates to a kind of slip copper coin pad welding machine structure, also relate to the method for using this slip copper coin pad welding machine structure to carry out the part welding.
Background technology
When automobile body welding is used the welding of resistance spot welding soldering turret, the fixed electrode head is close to steel plate to be welded, promoting the traveling electrode head by cylinder then moves to the fixed electrode head, then with first extruding of fixed electrode steel plate to be welded, and pass to certain electric current simultaneously, the lasting regular hour makes metal alloying together, reaches welding effect.
This resistance electric welding because by employee's manual operations, is difficult to guarantee that electrode is vertical in steel plate to be welded in welding process, cause the defective such as depression, distortion of bodywork surface solder joint easily, influences vehicle body quality of welding spot and attractive in appearance.For the problems such as solder joint depression, distortion that leak outside, generally take to increase the copper coin pad at the assembly platform and weld to prevent depression, distortion generation of defects.Copper coin is close to steel plate to be welded, and two electrodes are close to copper coin and steel plate to be welded from two ends, pushes then, switching on reaches welding effect.This method has well solved solder joint depression, distortion problem, but this method has a lot of drawbacks: electrode tip skids from copper coin easily and falls, as the solder joint that leaks outside is distributed in 60CM when long, uses whole face length stripe shape copper coin to weld.Under the impulsive force of electrode, after welding reached 500 solder joints, copper coin deformed crooked so that puts recessed bodywork surface; The long contact with weld of copper coin profile caused shunting, causes the welding quality shakiness; Because the impulsive force of electrode, the copper coin wearing and tearing are very fast, need to change the monoblock copper coin, increase cost; And whole face length stripe shape copper coin Heavy Weight, the inconvenience of taking during operation.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, a kind of slip copper coin pad welding machine structure is provided, the method for using this slip copper coin pad welding machine structure to carry out the part welding also is provided.Solve the problem of solder joint depression, distortion, improved the quality attractive in appearance of vehicle body solder joint; And it is in light weight to fill up the welding machine structure, is convenient to operation, has reduced the consume of copper coin, has saved cost.
Technical solution of the present invention is (referring to accompanying drawing):
A kind of slip copper coin pad welding machine structure, comprise rolling guide (3), fixedly the support transverse slat (2) of rolling guide (3) and fixing spacing iron block (5), be installed in the spacing support bar (6) at rolling guide (3) two ends, roller set (7) in rolling guide (3) slip, the little copper coin (8) that is connected with roller set (7) by connecting plate (1), promote the soldering turret slurcam (9) that roller set (7) is slided at rolling guide (3), described support transverse slat (2) is provided with the alignment pin (4) for fixing whole pad welding machine structure.
Further, described support transverse slat (2) and described fixing spacing iron block (5) are welded on the side of described rolling guide (3).
Further, the hole that bolt (10) passes on the described little copper coin (8) is fixed on the described connecting plate (1), and described little copper coin (8), connecting plate (1) and roller set (7) form a whole bindiny mechanism.
The method of using slip copper coin pad welding machine structure to carry out the part welding may further comprise the steps:
(1) pick up spacing iron block (5), will support alignment pin (4) on the transverse slat (2) and put into a hole on the part, it is precisely fixing to fill up the welding machine structure, prevents from filling up the welding machine structure at mobile welding hour offset; With spacing iron block (5) applying part, guarantee weld zone height and the balance of little copper coin (8), spacing support bar (6) contacts with the soldering part bottom, form supplemental support, and the roller set (7) that prevents from insulating skids off;
(2) place after, the regions perpendicular that little copper coin (8) and connecting plate (1) are pressed close to soldering part, insulation roller set (7) are mobile along rolling guide (3) under external force;
(3) fixed pole of operation soldering turret is introduced into the inboard, weld zone and presses close to weldment, and the float electrode of operating soldering turret then enters treats welding zone, and this moment, electrode tip was pressed close to little copper coin (8); During mobile soldering turret, the float electrode bar drives soldering turret slurcam (9) and copper sheet connecting plate (1), and little copper coin (8) arrival needs the weld welding of switching on;
(4) when arriving last operating point, weld zone, assembly pulley can not move under the stopping of spacing support bar (6), and welding job is herein finished;
(5) withdraw from soldering turret, pick up spacing iron block (5), upwards take out pad welding machine structure, wait for the installation welding of next chassis.
The present invention compared with prior art has following advantage: slip copper coin pad welding machine structure of the present invention, because it is tight that the small pieces copper coin that slides with fixedly the weldment contact-making surface is little, is fitted, under the impulsive force of electrode, be not easy bending, avoid the some generation of recessed bodywork surface defective; Well solve the problem of solder joint depression, distortion, improved the quality attractive in appearance of vehicle body solder joint; The pad bit copper plate slide mechanism of resistance spot welding is in light weight, is convenient to operation, has reduced the consume of copper coin, has saved cost.This pad welding machine structure is convenient to dismounting, maintaining and is deposited.
