Abstract
The utility model discloses an auxiliary structure improving the quality of exposed welding spots of a vehicle body. The auxiliary structure comprises a copper plate. The copper plate is arranged on a welding tong arm of a pair of welding tongs through a connecting block structure which can conduct position adjustment on the copper plate in the throat width direction and the throat depth direction of the pair of welding tongs. The position adjustment of the copper plate arranged on the pair of welding tongs is convenient. Therefore, the auxiliary structure improving the quality of the exposed welding spots of the vehicle body is suitable for spot welding protection of vehicle bodies in white of different structures, capable of avoiding the limitation that the copper plate is difficult to additionally arrange on a welding clamp, simple in manufacturing technology and low in cost.
Description
Technical field
The utility model relates to the automotive body welding technical field, especially relates to a kind of vehicle body that promotes and exposes the auxiliary body of quality of welding spot.
Background technology
Along with the continuous progress of high speed development and the automobile technology of automotive engineering, people are more and more higher to the appearance requirement that body in white exposes solder joint, and the good quality of welding spot that exposes also starts to become one of restrictive condition that the client buys gradually.
In the body of a motor car manufacturing process, the solder joint that exposes of locating for body in white hood, luggage-boot lid, door lock etc. generally adopts indirect welding or copper coin protection Welding to protect it, promotes its presentation quality.Adopt indirect welding technique, cost is higher, and car enterprise adopts less, and a lot of cars enterprise adopts copper coin protection Welding to promote vehicle body to expose quality of welding spot.
Existing copper coin protection Welding adopts installs copper coin on soldering cramping apparatus, carry out copper coin protection spot welding lifting and expose quality of welding spot.But for some, be in the solder joint that exposes on curved surface, the needs that coordinate with curved panel piece due to the copper coin on fixture, often need us to adjust copper coin by manual grinding, it is fitted with the curved panel piece gap as far as possible, the difficulty that this has brought on the copper coin process for machining and manufacturing, increased workload, and can't procurement of replacement parts for production division, be unfavorable for producing in enormous quantities, have the use limitation.In addition, for the larger-size vehicle body of vehicle, its quantity that exposes solder joint is more, often even tens of copper billets need to be installed on fixture, has brought the pressure on the cost.
The utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of vehicle body that promotes and exposes the auxiliary body of quality of welding spot, to reach the simple purpose of wide accommodation and manufacturing process.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of vehicle body that promotes exposes the auxiliary body of quality of welding spot, comprise copper coin, described copper coin is by being located at the connecting block structure that copper coin carries out the position adjustment in throat opening direction and the throat depth direction of soldering turret on the soldering turret arm of soldering turret.
Described connecting block structure comprises contiguous block I, contiguous block II, contiguous block III, the contiguous block I is located on the soldering turret arm, the contiguous block II is located on the contiguous block I, the contiguous block III is located on the contiguous block II by bolt, on the contiguous block III, the face of corresponding soldering turret electrode is provided with waist-shaped hole, and copper coin is located in waist-shaped hole on the contiguous block III.
Described copper coin is located in waist-shaped hole on the contiguous block III by spring shim.
On described copper coin, corresponding upper soldering turret electrode is provided with half waist type groove.
The utility model compared with prior art, has the following advantages: the copper coin position that arranges on soldering turret is easy to adjust, is suitable for the body in white spot welding protection of different structure, avoids on weld jig setting up the limitation of copper coin difficulty, and manufacturing process is simple, and cost is low.
Description of drawings
Below the expressed content of each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is the utility model auxiliary body organigram.
In figure: 1. soldering turret, 2. soldering turret arm, 3. contiguous block I, 4. contiguous block II, 5. contiguous block III, 6. spring shim, 7. copper coin.
The specific embodiment
Below contrast accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1; a kind of vehicle body that promotes exposes the auxiliary body of quality of welding spot; this auxiliary body is arranged on the soldering turret arm 2 of soldering turret 1; it comprises copper coin 7 and the connecting block structure that the protection solder joint is used; copper coin 7 is arranged on connecting block structure; connecting block structure is arranged on soldering turret arm 2, by connecting block structure, copper coin can be carried out the position adjustment in throat opening direction and the throat depth direction of soldering turret, is suitable for the body in white spot welding protection of different structure.
Connecting block structure specifically comprises three contiguous block I 3, contiguous block II 4, contiguous block III 5, contiguous block I 3 is located on soldering turret arm 2, contiguous block II 4 is located on contiguous block I 3, contiguous block III 5 is located on contiguous block II 4 by bolt, on the contiguous block III, the face of corresponding soldering turret electrode is provided with waist-shaped hole, and copper coin 7 is located in waist-shaped hole on contiguous block III 5 by spring shim 6.Three contiguous block materials are nylon material, and quality is light, is convenient to fitting operation.When welding, copper coin 7 can, by spring shim 6 distortion fine settings, adapt to actual welding position needs.
While adjusting the copper coin position, can adjust the throat depth direction extension elongation of copper coin at soldering turret by adding or cut pad between contiguous block II and contiguous block III; Adjust by fixed position in the waist-shaped hole of spring shim on the contiguous block III; adjust the distance between copper coin and upper and lower soldering turret electrode; namely adjust the position of copper coin on the throat opening direction of soldering turret, adapt to the status requirement of copper coin to the body in white spot welding protection of different structure.
Copper coin is selected the copper coin of CuCr1Zr material, on copper coin, to be provided with the degree of depth be 3mm half waist type groove to corresponding upper soldering turret electrode, adjust copper coin phase butt welding tongs electrode position by this half waist type groove, guarantee when the soldering turret electrode is closed to be in this half waist type groove, prevent soldering turret electrode skew in welding process.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
