Abstract
The utility model discloses a kind of rear driving axle back-cover and reinforcing ring boxing structure of auto parts and components manufacture technology field, including the rear driving axle housing being spliced by upper semi-body, lower semi-body, back-cover, reinforcing ring and set square, the back-cover, reinforcing ring are connected with the annular stopper being combined into by upper semi-body, lower semi-body and set square by girth joint, the set square is connected with upper semi-body and lower semi-body by longitudinal seam, the lap-joint of the girth joint and longitudinal seam, longitudinal seam are located at the top of girth joint.The beneficial effects of the utility model are：When carrying out the assembled welding of rear driving axle housing, first carry out the welding of girth joint, ensure that upper semi-body, lower semi-body, back-cover, reinforcing ring and set square are effectively merged, carry out longitudinal seam welding again afterwards, and longitudinal seam is set to snap on girth joint, it so can effectively avoid occurring phenomena such as jumping arc in lap-joint and producing weld defect, make welded seal firm, finally avoid occurring oil leakage phenomenon in use.
Description
Technical field
It the utility model is related to auto parts and components manufacture technology field, more particularly to a kind of rear driving axle back-cover and reinforcing ring
Boxing structure.
Background technology
Rear driving axle welding assembly for rushing weldering formula structure, main production technology are by various punchings by welding technique
Tabletting part and the parts of correlation weld together, and the feelings that the weld seam of rear process needs to be overlapped with preceding process weld seam be present
Condition, often this overlap joint place different degrees of weld defect can all occur, finally influence product quality.For back-cover and add
The welding of strong ring girth joint, current technique are first to carry out the welding of longitudinal seam, carry out back-cover and reinforcing ring girth joint again afterwards
Welding, can have following two situations in overlapped points position when this welding procedure carries out boxing seam welding：1st, welding arc
Exist when reaching overlapped points and jump arc phenomenon, produce weld defect；2nd, can be away from overlap joint when welding arc passes through overlapped points
Locate side and produce small gap, i.e., it is lack of penetration.Both the above defect can all cause to leak in lap-joint's (stress concentration point)
The situation of oil occurs, and causes main engine plants and the complaint of customer.
Utility model content
To overcome the existing rear driving axle welding assembly for rushing weldering formula in back-cover and reinforcing ring girth joint and longitudinal seam lap-joint
Easily there is gap, the deficiencies of causing oil leak situation, technical problem to be solved in the utility model is：There is provided a kind of welding more
Reliably, the rear driving axle back-cover of better tightness and reinforcing ring boxing structure.
Technical scheme is used by the utility model solves its technical problem：
Rear driving axle back-cover and reinforcing ring boxing structure, including by upper semi-body, lower semi-body, back-cover, reinforcing ring and set square
The rear driving axle housing being spliced, the annular of the back-cover, reinforcing ring with being combined into by upper semi-body, lower semi-body and set square
Seam is connected by girth joint, and the set square is connected with upper semi-body and lower semi-body by longitudinal seam, the girth joint and vertical weldering
The lap-joint of seam, longitudinal seam are located at the top of girth joint.
It is further the lap-joint of the girth joint and longitudinal seam, to be provided between longitudinal seam and the girth joint of both sides
Arc transition weld seam.
It is further that the radius of the arc transition weld seam is not less than girth joint and the width of longitudinal seam.
It is further that the upper semi-body, lower semi-body, back-cover, the stitching portion of reinforcing ring and each lamellar body part of set square are set
There is pad to carry out pre-determined bit.
The beneficial effects of the utility model are：When carrying out the assembled welding of rear driving axle housing, in weld seam, lap-joint makes
Longitudinal seam is located at the top of girth joint, i.e., first carries out the welding of girth joint, can so ensure upper semi-body, lower semi-body, back-cover plus
Strong ring and set square are effectively merged, and carry out longitudinal seam welding again afterwards, and longitudinal seam is snapped on girth joint, this
Sample can effectively avoid occurring phenomena such as jumping arc in lap-joint and producing weld defect, make welded seal firm, finally avoid making
Occurs oil leakage phenomenon during.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Mark is 1- upper semi-bodies in figure, and 2- lower semi-bodies, 3- back-covers, 4- reinforcing rings, 5- set squares, 6- girth joints, 7- is vertical to be welded
Seam, 8- pads.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, rear driving axle back-cover of the present utility model and reinforcing ring boxing structure, including by upper semi-body 1, lower half
The rear driving axle housing that body 2, back-cover 3, reinforcing ring 4 and set square 5 are spliced, the back-cover 3, reinforcing ring 4 with by upper half
The annular stopper that body 1, lower semi-body 2 and set square 5 are combined into is connected by girth joint 6, the set square 5 and upper semi-body 1 and under
Halfbody 2 is connected by longitudinal seam 7, and the lap-joint of the girth joint 6 and longitudinal seam 7, longitudinal seam 7 is located at the top of girth joint 6.This
Structure is that girth joint 6 is different from the overlapping mode of longitudinal seam 7 relative to the structure main distinction used at present, existing overlap joint
Structure be longitudinal seam 7 under, girth joint 6 is upper, and structure of the present utility model is just in contrast, using the structure of the application
In welding, because back-cover 3 and reinforcing ring 4 have first been fixed on one by girth joint 6 with upper semi-body 1, lower semi-body 2 and set square 5
Rise, then would not occur phenomena such as jumping arc and minim gap when carrying out the welding of longitudinal seam 7, thus using the application structure more
It is easily guaranteed that the reliability and sealing of welding.
Further, the lap-joint of the girth joint 6 and longitudinal seam 7, sets between the girth joint 6 of longitudinal seam 7 and both sides
Have an arc transition weld seam, the preferred scheme of the arc transition weld seam for weld seam radius not less than girth joint 6 and longitudinal seam 7
Width.The purpose that arc transition weld seam is set be in order to further carry out a transition seal to the lap-joint of weld seam, can be effective
Block the minim gap occurred by thermal stress deformation in weld seam lap-joint.
, can be first in upper semi-body 1, lower semi-body 2, back-cover 3, reinforcing ring 4 and set square 5 before the welding of girth joint 6 is carried out
The stitching portion of each lamellar body part sets pad 8 to carry out pre-determined bit.On the one hand each lamellar body part can be made by first setting pad 8 to position
It is stably connected with, is easy to subsequent transfer and welding, on the other hand can also ensures the welding in follow-up girth joint 6 and longitudinal seam 7
During be not in larger thermal stress deformation, improve welding quality.
The rear driving axle back-cover and reinforcing ring boxing structure of the application, is overlapped on girth joint as a result of by longitudinal seam
The structure of side, substantially increases welding quality, avoids and the problem of jumping arc and minim gap occurs in weld seam lap-joint, has very
Good practicality and economic value.
