The utility model has the advantages that the structure is compact, the disassembly and the maintenance are convenient, no welding mark is reversed on the surface of an automobile body when spot welding is carried out to the automobile body, no current distribution is caused during welding, so that the welding quality of the appearance of the automobile body can be ensured.
Description
Technical field
The utility model relates to the automobile body welding technical field, is specifically related to a kind of vehicle body spot welding copper pad assemble mechanism.
Background technology
Outer covering piece need carry out means of spot welds in order to guarantee weld strength in the auto production line, and common welding manner can stay the welding marking on part after the solder joint welding is finished, influence the vehicle body presentation quality.At present the vehicle body spot welding copper pad assemble mechanism that uses is that a solder joint is provided with a copper pad, is connected by whippy steel silicon chip between copper pad and the anchor clamps.All there is very big problem in connected mode between this copper pad and copper pad and the anchor clamps, the monolithic copper pad is little in when welding and part contact-making surface, stress surface is just little, soldering turret pressure owing to soldering turret when compressing copper pad will stay the welding marking on part, influence attractive in appearance, therefore this copper pad needed to carry out the reconditioning that cooperates with part before using, in case the reconditioning welding quality that will have influence on the vehicle body outward appearance not in place.Be connected with silicon steel sheet between copper pad and the anchor clamps, silicon steel sheet conducts electricity, and can cause the loss of part electric current in the moment of soldering turret energising, influences welding quality.The effect of silicon steel sheet is exactly when welding when copper pad does not reach part, elasticity by silicon steel sheet makes copper pad realize welding near part, one side that silicon steel sheet is connected with anchor clamps is fixed, when soldering turret pulling copper pad, just there is one to send out angle, this angle can make soldering turret extrude defective on part, there is jump in two tie points, time has been grown, and silicon steel sheet ruptures easily, and the connecting portion of silicon steel sheet is softer, soldering turret has on copper pad when playing weldering a bit partially slightly, copper pad will deflect, and part is broken, and copper pad is broken in serious meeting, wearing and tearing in a single day of this vehicle body spot welding copper pad assemble mechanism or damage, dismounting and maintenance are all very inconvenient.
Summary of the invention
The utility model provides a kind of vehicle body spot welding copper pad assemble mechanism, and dismounting, easy to maintenance can not stay the welding marking at piece surface after welding is finished, do not have the shunting of electric current during welding, guarantees the welding quality of vehicle body outward appearance.
A kind of vehicle body spot welding copper pad assemble mechanism comprises copper pad, upper spring, back-up block, lower spring, removable pin, set bolt, and the two ends of described copper pad bottom are fixed with two removable pins, and the other end of described removable pin is provided with set bolt; Described upper spring, back-up block, lower spring are set on the removable pin successively, and an end of upper spring withstands on the copper pad, and the other end and back-up block offset, and described lower spring one end withstands on the back-up block, and the other end and set bolt offset.
As preferably, described removable pin is fixed by installing plate and copper pad, makes copper pad more durable, prolongs the service life of copper pad.
As preferably, fix with the copper pad fastening bolt between described copper pad and the installing plate.
As preferably, described back-up block is the U type, and the two ends of U type are set on the removable pin, saves the material of back-up block, fixes during convenient simultaneously the use.
As preferably, described back-up block is that insulating materials is made, and more preferably nylon material does not have the shunting of electric current when welding, and guarantees the welding quality of vehicle body outward appearance.
As preferably, be added with a locking gasket between described set bolt and the lower spring, increase fixing firm degree.
Fixture component of the present utility model is to adopt machined to form, and all assembling apertures all are the same, and the bolt of same specification is adopted in the connection of fixture component, has improved the versatility of parts, for convenience detach and maintenance.
Removable pin of the present utility model and back-up block are movable, and the centre is added with upper spring, directly contact copper pad when part is put on the anchor clamps, and the height of copper pad can carry out automatic fine tuning by upper spring.
The utility model is fixed on the anchor clamps by back-up block in use, height and direction can be regulated, wearing and tearing between removable pin and the back-up block are little, what whole vehicle body spot welding copper pad assemble mechanism wearing and tearing were more serious is exactly copper pad, when the copper pad serious wear, only need copper pad is changed, in case copper pad wearing and tearing back only need be unclamped the copper pad that more renews with two copper pad fastening bolts of fixed copper backing plate and be got final product, need not entire mechanism is changed, the copper pad that more renews is simple to operate, general employee can operate, and reduces production costs.
The replacing operation of removable pin of the present utility model is also very simple, as long as two bolts that will be fixed on the anchor clamps are backed out, vehicle body spot welding copper pad assemble mechanism is taken out, again the set bolt below the removable pin is backed out, taken out lower spring, take out back-up block, the back-up block that more renews, load onto according to original assemble sequence and to get final product, the processing of back-up block is simple, only needs simple line cutting just can realize.
Copper pad of the present utility model is bigger than the copper pad surface area that uses in the prior art, the position of contact part is big, after finishing, welding can not stay the welding marking at piece surface, copper pad and installing plate are in one plane, do not have the crooked phenomenon of companion, when welding, part can not played distortion like this; Fixedly the back-up block of vehicle body spot welding copper pad assemble mechanism insulate, and does not have the shunting of electric current when welding, and guarantees the welding quality of vehicle body outward appearance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, vehicle body spot welding copper pad assemble mechanism comprises copper pad 1, installing plate 2, upper spring 3, back-up block 4, locking gasket 5, set bolt 6, the fastening screw 7 of copper pad, copper pad fastening bolt 8, the fastening screw 9 of back-up block, removable pin 10, lower spring 11.
