Shi Rongyi produces a large amount of internal stress between each flat parts, causes to produce substantial amounts of welding deformation in welding process, influences
End product quality.Therefore, it is necessary to a kind of new welding structure is studied, influence caused by reduce internal stress.
Utility model content
To overcome existing rear driving axle assembly stage casing one-shot forming welding easily to produce a large amount of internal stress, cause deformation of products
The deficiencies of, technical problem to be solved in the utility model is：The rear-guard that a kind of first spot welding positioning is continuously welded again is provided
Dynamic axle assembly stage casing pad determines structure.
Technical scheme is used by the utility model solves its technical problem：Rear driving axle assembly stage casing pad is tied surely
Structure, including the rear driving axle housing being assembled into by upper semi-body, lower semi-body, back-cover, reinforcing ring and set square, in the above lamellar body
The stitching portion of part is provided with multiple pads, and the pad is fixed into an entirety by each lamellar body part pad.
It is further that eight pads are provided between the upper semi-body and lower semi-body, this eight pads are located at respectively
At eight end points of upper semi-body and lower semi-body both ends Mosaic face.
It is further that the back-cover and the stitching portion of upper semi-body and lower semi-body are provided with four pads, four pads
It is uniformly arranged around the back-cover center of circle, and two of which pad is connected with upper semi-body, two pads are connected with lower semi-body.
It is further that the stitching portion of the reinforcing ring and upper semi-body and lower semi-body is provided with four pads, four welding
Point is uniformly arranged around ring center is strengthened, and two of which pad is connected with upper semi-body, and two pads are connected with lower semi-body.
It is further that the stitching portion of the set square and upper semi-body and lower semi-body is provided with two pads, two welding
Point is respectively positioned at the middle part of hypotenuse above and below set square.
The beneficial effects of the utility model are：Set by the stitching portion of each lamellar body part in rear driving axle assembly stage casing
Pad, on the one hand assembling positioning can be carried out to total, be easy to follow-up transhipment to weld, on the other hand can eliminate and subsequently connect
Planted agent's force deformation that continuous welding is formed, can effective Improving The Quality of Products, while whole technological process can be shortened, save production
Place and fund input.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
It is 1- upper semi-bodies to be marked in figure, 2- lower semi-bodies, 3- back-covers, 4- reinforcing rings, 5- set squares, 6- pads.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, rear driving axle assembly stage casing pad of the present utility model determines structure, including by upper semi-body 1, lower half
The back axle main body that body 2, back-cover 3, reinforcing ring 4 and set square 5 are assembled into, it is provided with the stitching portion of the above lamellar body part multiple
Pad 6, the pad 6 are fixed into an entirety by each lamellar body part pad.Pad 6 is preferably by all lamellar body parts
All it is configured again after assembly well, to control the overall structure of assembly, special weldering is gone to again after all parts are all stable
The continuous welding of weld seam is carried out on machine.
The welding structure in traditional rear driving axle assembly stage casing is generally assembled good rear one-shot forming welding, or according to elder generation
Order, which carries out welded structure, both frame modes in assembly, afterwards respectively advantage and disadvantage, the former efficiency high, but in easily occurring
Stress deformation, the latter's deformation is small, but low production efficiency.And it is described herein first carry out assembled spot welding positioning, then carry out continuous
Welded structure, you can eliminate the influence of internal stress, production efficiency can be improved again.
The setting of each pad 6 should meet that transhipment requirement is defined, pad to ensure that each lamellar body part can be stably connected with
6 quantity can not be too many, easily causes to deform, and the preferred scheme between each part is as follows：
Eight pads 6 are provided between the upper semi-body 1 and lower semi-body 2, this eight pads 6 are located at upper semi-body 1 respectively
At eight end points of the both ends Mosaic face of lower semi-body 2.Upper semi-body 1 is two portions maximum in rear driving axle assembly with lower semi-body 2
Part, the Mosaic face of both parts are the Mosaic faces in the middle part of two circular pipelines at both ends, to ensure the reliability of connection, weldering
Contact 6 is arranged at eight end points of two pipeline Mosaic faces.
The back-cover 3 and the stitching portion of upper semi-body 1 and lower semi-body 2 are provided with four pads 6, and four pads 6 are around back-cover 3
The center of circle is uniformly arranged, and two of which pad 6 is connected with upper semi-body 1, and two pads 6 are connected with lower semi-body 2.
The stitching portion of the reinforcing ring 4 and upper semi-body 1 and lower semi-body 2 is provided with four pads 6, and four pads 6 are around adding
The strong center of circle of ring 4 is uniformly arranged, and two of which pad 6 is connected with upper semi-body 1, and two pads 6 are connected with lower semi-body 2.
The stitching portion of the set square 5 and upper semi-body 1 and lower semi-body 2 is provided with two pads 6, and two pads 6 are distinguished
Positioned at the middle part of set square hypotenuse about 5.
Using above-mentioned pad arrangement, totally 24 solder joints are Best Point fixed number amount to tow sides, can be effective
Ensure welding quality, it is same that larger welding deformation can be avoided to produce.Secondly, fixed parts progress is put subsequently to assembled
Relatively low to the positioning requirements of workpiece during welding, operation is simpler, while when longitudinal seam welding is carried out, can avoid
The caused welding deformation because larger weld seam contracting.
