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 welding and assembling technics technical field, be related specifically to a kind of Welding spot protective device.
Background technology
When production automobile body-in-white, generally adopt the many of electric resistance welding, and in electric resistance welding, spot welding is the most conventional, the solder joint vestige caused in pinpoint welding procedure is general more ugly.Now, in order to increase the structural strength of vehicle body, a lot of vehicles all needs to weld on secondary surface part even first-surface part, adopts traditional spot welding to cause bad order.For avoiding above-mentioned situation, some producer have employed the new technologies such as monolateral spot welding, electronic curing, but these new technology prices are high, is difficult to promote.
Summary of the invention
The object of the invention is to propose a kind of Welding spot protective device with low cost, easy to use, for the plane protection of body in white surface solder joint, improve the appearance looks elegant degree of automobile.
Welding spot protective device of the present invention comprises electrode tip holder and is installed on electrode stem, the electrode cap on electrode tip holder; key is described electrode tip holder to be provided with an insulating support extended to electrode cap direction; described insulating support is provided with one piece of copper coin, described copper coin contacts with electrode cap.
The principle of Welding spot protective device of the present invention improves solder joint plane quality by the area of Diffusion Welding contact surface; be exactly the contact area being expanded electrode cap and panel beating by copper coin specifically; thus the compression shock that decomposition soldering turret brings to solder joint; and electrode cap is pressed on copper coin instead of is pressed on sheet metal component during soldering turret welding; the flatness of copper coin can be utilized to ensure there is not torsional deformation in solder joint, ensures that pad surface impression can meet quality requirement.In addition, this Welding spot protective device is installed on soldering turret, and move along with the stroke of soldering turret, more convenient to operate.
Further, described insulating support is made up of the spring of the insulation board be installed on electrode tip holder and connection insulation board and copper coin, spring can contraction and stretching under the ordering about of soldering turret pressure, thus make only when welding copper coin just contact with electrode cap, while guarantee welding quality, reduce the possibility that electrode cap damages, the more important thing is, spring can absorb the impact vector in soldering turret running, reduces the impact to sheet metal component further, thus improves quality of welding spot.
Further, described copper coin is arc surface away from the end face of the side of electrode cap, can both realize copper coin and metal plate face keeping parallelism when can ensure to contact different arcuate surfaces, improves the aesthetics of solder joint further.
Further, described insulating support is provided with protecting sheathing between insulation board and copper coin, to avoid the minor impact lesion electrode cap when soldering turret operates.
Further, described spring is connected and fixed with insulation board, copper coin respectively by bolt, and described insulation board is connected and fixed by threaded engagement and electrode tip holder, to be convenient for changing insulating support or copper coin.
Further, described insulation board is that bakelite plate is made, and the insulating properties of bakelite plate, heat resistanceheat resistant performance and satisfactory mechanical property, not only can improve insulativity and the mechanical strength of insulating support, and the heat that when can also avoid soldered, electrode tip holder produces simultaneously melts.
Welding spot protective device structure of the present invention is simple, with low cost, easy to use, effectively can improve quality of welding spot when being applied to body in white surface soldered, and then improves the appearance looks elegant degree of automobile.
Accompanying drawing explanation
Fig. 1 is the structural representation of Welding spot protective device of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1; the Welding spot protective device of the present embodiment comprises electrode tip holder 1 and is installed on electrode stem 2, the electrode cap 3 on electrode tip holder 1; electrode tip holder 1 utilizes threaded engagement one piece of bakelite plate is installed and make to obtain insulation board 4; this insulation board 4 has been bolted spring 5; the other end of spring 5 has been bolted copper coin 6, and copper coin 6 can contact with electrode cap 3 when spring 5 compresses.
Copper coin 6 is arc surface away from the end face of the side of electrode cap 3, can both realize copper coin 6 and panel beating 7 keeping parallelism when can ensure like this to contact different arcuate surfaces, improves the aesthetics of solder joint further.
In use, copper coin 6 is contacted with panel beating 7, then firmly press-welding pliers, spring 5 is compressed, and then copper coin 6 is contacted with electrode cap 3, so just expanded the contact area of electrode cap 3 and panel beating 7 by copper coin 6, thus the compression shock that decomposition soldering turret brings to solder joint, and electrode cap 3 is pressed on copper coin 6 instead of is pressed on panel beating 7 during soldering turret welding, the flatness of copper coin 6 can be utilized to ensure there is not torsional deformation in solder joint, ensures that pad surface impression can meet quality requirement.During moving electrode holder, copper coin 6 moves with electrode cap 3, more convenient to operate.
