Abstract
Rear driving axle welding assembly of the present invention, lower semi-body are provided with through hole, in addition to the purge cock being welded to connect with through hole, and the welding ends of purge cock is provided with welding step, and the solder side for welding step and through hole is all interval with multiple groove structures for being used to accept solder；Groove is set excessively to arrive welding step on purge cock；The inside bending of the splicing edge of upper semi-body and lower semi-body, makes longitudinal seam cave inward.The present invention can also increase weld width, for that welding deformation may be caused to reserve deformation space, not interfere with the assembled gap between upper semi-body and lower semi-body by setting welding step spacing come welding position progress in the welding ends of purge cock；And by setting groove structure on the solder side of welding step and through hole, make purge cock and through hole weld can accommodate the amount of solder and greatly increase, welding deformation amount can be reduced indirectly, the penetration of weld seam and the weld strength of weld can be improved simultaneously, strengthens integrally-built strength and stability.
Description
Technical field
The present invention relates to field of automobile, especially a kind of rear driving axle welding assembly.
Background technology
In automobile industry, for rear driving axle welding assembly typically using weldering formula structure is rushed, main production technology is to pass through
Welding technique welds together the parts of various punched pieces and correlation, and the welding process of preceding process can produce welding and become
Shape finally influences welding quality so as to influence the welding of subsequent handling.In current rear driving axle welding assembly, due to spiral shell of draining the oil
The welding of plug, the assembled welding of upper semi-body and lower semi-body can be impacted, weld welding deformation meeting caused by purge cock
Cause the assembled gap of upper semi-body and lower semi-body excessive, so as to influence the welding quality of longitudinal seam between upper semi-body and lower semi-body,
Cause rear driving axle welding assembly overall structure stability inadequate, serious potential safety hazard be present.
The content of the invention
The technical problems to be solved by the invention are：A kind of rear driving axle welding assembly is provided, welding can be effectively reduced and put
Welding deformation caused by whelk plug, improve weld strength and integrally-built stability.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：Rear driving axle welding assembly, including it is relative
The stitching portion of the upper semi-body and lower semi-body for splicing and being welded to connect, upper semi-body and lower semi-body is longitudinal seam, is set on the lower semi-body
There are through hole, in addition to the purge cock being welded to connect with through hole, the welding ends of the purge cock is provided with welding step, welding bench
The solder side of rank and through hole is all interval with multiple groove structures for being used to accept solder；Groove mistake is set on the purge cock
Spend welding step；The inside bending of splicing edge of the upper semi-body and lower semi-body, makes longitudinal seam cave inward.
It is further：The cross sectional shape of the groove structure is triangle, trapezoidal, rectangle or semicircle.
The beneficial effects of the invention are as follows：The present invention in the welding ends of purge cock by setting welding step come welding position
Carry out spacing, can also increase weld width, for that welding deformation may be caused to reserve deformation space, do not interfere with upper semi-body and under
Assembled gap between halfbody；And by welding step and through hole solder side on groove structure is set, make purge cock and
The amount that through hole weld can accommodate solder greatly increases, and can reduce welding deformation amount indirectly, while can improve the penetration of weld seam
With the weld strength of weld, integrally-built strength and stability is strengthened.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the sectional view of purge cock and through hole weld；
In figure mark for：1- upper semi-bodies, 2- lower semi-bodies, 3- longitudinal seams, 4- purge cocks, 5- welding step, 6- grooves.
Embodiment
For the ease of understanding the present invention, the present invention is further detailed below in conjunction with the accompanying drawings.
As shown in figure 1, rear driving axle welding assembly disclosed in this invention is made up of upper semi-body 1 and lower semi-body 2, upper semi-body
1 and lower semi-body 2 using to being welded to connect after spelling, weld between the two is longitudinal seam 3, and lower semi-body 2 is provided with through hole, drained the oil
Plug screw 4 is arranged in the through hole of lower semi-body 2, due to first welding purge cock 4 during installation purge cock 4 welding can be caused to become
Shape, so that the deformation of longitudinal seam 3 and spacing between upper semi-body 1 and lower semi-body 2 expand, welding quality can be had a strong impact on, in order to
The generation of this phenomenon is avoided, as shown in Fig. 2 the present invention is provided with welding step 5, and son weldering in the welding ends of purge cock 4
The solder side for connecing step 5 and through hole has been arranged at intervals multiple groove structures, and welding step 5 carries out spacing to purge cock 4, makes to lead to
Hole is resisted against at welding regulation 5, and the space of a receiving welding material is formed between welding regulation 5 and through hole, while is also weldering
Connect deformation and reserved space, then welding deformation will not be to development at longitudinal seam 3, and above-mentioned groove structure is used to accept welding material
Material, is fastened in groove structure after making welding material cooled and solidified, makes between welding material and purge cock 4 and lower semi-body 2
Contiguity is improved, and so as to improve the weld strength of weld, further improves the resistance to overturning of assembly.Draining the oil
Groove 6 is also provided with plug screw 4 excessively to welding step 5, welding material can flow into welding step 5 along groove 6 during welding, simultaneously
Welding material filling full weld can be covered on groove 6 after connecing step 5, can improve the conjugation of welding material and purge cock 4.For
Further influence caused by avoiding welding deformation, the inside bending of splicing edge between upper semi-body 1 and lower semi-body 2 so that vertical
Weld seam 3 caves inward, and on the one hand improves the saturation of welding material, is on the other hand alternatively welding deformation headspace.
As shown in Fig. 2 the cross sectional shape of groove structure is triangle, trapezoidal, rectangle or semicircle.
