Abstract
The invention provides a welding spot protective device with low cost and convenience in use, which is used for plane protection of a welding spot on the surface of a body-in-white and improving aesthetics of appearance of an automobile. The welding spot protective device comprises an electrode holder, as well as an electrode pole and an electrode cap, which are arranged on the electrode holder, wherein an insulated support extending toward to the direction of the electrode cap is mounted on the electrode holder, a copper plate is mounted on the insulated support, and the copper plate is in contact with the electrode cap. The welding spot protective device provided by the invention is in the principle that area of welding contact surface is diffused to improve plane quality of the welding spot, namely contact area between the electrode cap and a metal plate is enlarged by virtue of the copper plate, thus pressure impact to the welding spot by welding tongs is decomposed, the electrode cap is pressed on the copper plate rather than the metal plate when the welding tongs are used for welding, planarity of the copper plate can be used for guaranteeing that the welding spot has no distortion or deformation, and indentation on the surface of the welding spot can be guaranteed to meet quality requirements. The welding spot protective device provided by the invention can move along a stroke of the welding tongs and is more convenient to operate.
Description
Technical field
The invention belongs to the welding and assembling technics technical field, specially refer to a kind of solder joint protective device.
Background technology
When producing automobile body-in-white, generally adopt the many of electric resistance welding, and spot welding is the most commonly used in the electric resistance welding, the solder joint vestige that causes in the pinpoint welding procedure is general more ugly.Now, in order to increase the structural strength of vehicle body, a lot of vehicles all need be welded on secondary surface part even one-level face component, adopts traditional spot welding will cause bad order.For avoiding above-mentioned situation, some producer has adopted new technologies such as monolateral spot welding, electronic curing, but these new technology expensive are difficult to promote.
Summary of the invention
The objective of the invention is to propose a kind of solder joint protective device with low cost, easy to use,, improve the appearance looks elegant degree of automobile to be used for the plane protection of body in white surface solder joint.
Solder joint protective device of the present invention comprises electrode tip holder and is installed on electrode stem, the electrode cap on the electrode tip holder; Key is to be equipped with on the said electrode tip holder insulating support that extends to the electrode cap direction; A copper coin is installed on the said insulating support, and said copper coin contacts with electrode cap.
The principle of solder joint protective device of the present invention is that the area through the Diffusion Welding contact surface improves solder joint plane quality; Be exactly the contact area that enlarges electrode cap and panel beating through copper coin specifically; Thereby decompose the compression shock that soldering turret brings to solder joint; And soldering turret when welding electrode cap is pressed on the copper coin rather than is pressed on the sheet metal component, can utilize the flatness of copper coin to guarantee that torsional deformation does not appear in solder joint, guarantees that the solder joint surface indentation can satisfy quality requirement.In addition, this solder joint protective device is to be installed on the soldering turret, and moves along with the stroke of soldering turret, and is more convenient to operate.
Further, said insulating support is made up of the spring that is installed on the insulation board on the electrode tip holder and connects insulation board and copper coin, and spring can shrink under the ordering about of soldering turret pressure and stretching; Thereby only make that copper coin just contacts with electrode cap when welding, when guaranteeing welding quality, reduce the possibility that electrode cap damages; The more important thing is; Spring can absorb the impact vector in the soldering turret running, further reduces the impact to sheet metal component, thereby improves quality of welding spot.
Further, said copper coin is an arc surface away from the end face of a side of electrode cap, can both realize copper coin and panel beating face keeping parallelism in the time of can guaranteeing to contact different arcuate surfaces, further improves the aesthetics of solder joint.
Further, said insulating support is provided with protecting sheathing between insulation board and copper coin, to avoid the minor impact lesion electrode cap when soldering turret is operated.
Further, said spring is connected fixing respectively with insulation board, copper coin through bolt, and said insulation board is connected fixing with electrode tip holder through threaded engagement, to be convenient for changing insulating support or copper coin.
Further, said insulation board is that bakelite plate is processed, and the insulating properties of bakelite plate, heat resistanceheat resistant performance and satisfactory mechanical property not only can improve the insulativity and the mechanical strength of insulating support, and the heat that electrode tip holder is produced in the time of can also avoiding being soldered simultaneously melts.
Solder joint protective device of the present invention is simple in structure, with low cost, easy to use, can effectively improve quality of welding spot when being applied to the body in white surface soldered, and then improves the appearance looks elegant degree of automobile.
Description of drawings
Fig. 1 is the structural representation of solder joint protective device of the present invention.
The specific embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify.
Embodiment 1:
As shown in Figure 1; The solder joint protective device of present embodiment comprises electrode tip holder 1 and is installed on electrode stem 2, the electrode cap 3 on the electrode tip holder 1; Utilize on the electrode tip holder 1 threaded engagement be equipped with a bakelite plate process insulation board 4; This insulation board 4 is connected with spring 5 through bolt, and the other end of spring 5 is connected with copper coin 6 through bolt, and copper coin 6 can contact with electrode cap 3 when spring 5 compressions.
In use, copper coin 6 is contacted with panel beating 7, firmly pressure welding clamps then; Make spring 5 compressions, and then copper coin 6 is contacted with electrode cap 3, so just enlarged the contact area of electrode cap 3 with panel beating 7 through copper coin 6; Thereby decompose the compression shock that soldering turret brings to solder joint; And soldering turret when welding electrode cap 3 is pressed on the copper coin 6 rather than is pressed on the panel beating 7, can utilize the flatness of copper coin 6 to guarantee that torsional deformation does not appear in solder joint, guarantees that the solder joint surface indentation can satisfy quality requirement.When moving soldering turret, copper coin 6 is with electrode cap 3 motions, and is more convenient to operate.
