Abstract
The utility model discloses a reinforcing rib plate for the inner plates of a right front door and a left front door. The reinforcing rib plate comprises an elongated body, and is characterized in that a long groove is arranged along the edge of the long shaft of the body, a welding boss is arranged in the long groove, the welding boss is provided with eight spot welding points, the connection lines of the eight spot welding points form an arc line, the spot welding points are uniformly distributed at intervals on the arc line, the long groove is an arc-shaped groove, and the welding boss is positioned on the arc surface of the long groove. According to the reinforcing rib plate for the inner plates of the right and left front doors, through changing the welding technology, consistency of relative positions of parts is effectively ensured, stability of welding is increased, stability of size of a welding assembly is improved, welding stress is effectively reduced, performance and function of the parts are effectively ensured, harmful gas generated by arc welding is eliminated, and thereby air quality in a workshop is effectively improved.
Description
Technical field
The utility model relates to auto parts welding assembly, and concrete a kind of right left front door back veneer that refers to is strengthened gusset.
Background technology
During welding, inhomogeneous heating and cooling are stood at each position of part, cause inhomogeneous stress deformation, produce different stress deformations and stress.Arc-welding, heating area is large, the distortion of welding thermal transient is large, and weld seam shrinks and causes the distortion of postwelding unrelieved stress large, and this part is relatively elongated, and to send out torsional deflection thermogenetic also larger.Adopt resistance spot welding, point-like heating energy is eliminated thin plate buckling deformation.
Summary of the invention
Weak point for above-mentioned background technology, and the purpose of this utility model is to provide a kind of right left front door back veneer to strengthen gusset, guarantee welding front and back part conformability, increase part resistance to deformation intensity, guarantee can not cause and lose efficacy or abnormal sound because of distortion in the use procedure of postorder vehicle.
For achieving the above object, right left front door back veneer provided by the utility model is strengthened gusset, comprise strip shape body, it is characterized in that: along described long axis of body rim, be provided with elongated slot, in described elongated slot, be provided with welding boss, described welding boss is provided with eight weld nuggets, and the connection lead of eight weld nuggets forms circular arc line, and each weld nugget interval on circular arc line is uniformly distributed; Described elongated slot is arc-shaped slot, and welding boss is positioned on the arc surface of elongated slot.
The utility model has the advantage of: the utility model is by changing welding process, effectively guarantee the conformability of part relative position, increase the stability of welding, improve the stability of welding assembly size, actv. reduces welding stress, actv. guarantees performance and the functional requirement of part, cuts off the pernicious gas producing because of arc welding, and actv. improves workshop air quality.

In figure: body 1, elongated slot 2, welding boss 3, weld nugget 4, arc welding torch 5, arc-welding welding wire 6, arc weld join domain 7, steel pipe part 8, part of the steel plate 9, spot welding top electrode 10, spot welding bottom electrode 11.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Right left front door back veneer is as shown in the figure strengthened gusset, comprises strip shape body 1, along this long axis of body rim, is provided with elongated slot 2, is provided with welding boss 3 in elongated slot 2, and welding boss 3 is provided with weld nugget 4.
Elongated slot 2 is arc-shaped slot, and welding boss 3 is positioned on the arc surface of elongated slot 2; Weld nugget 4 is provided with eight, and the connection lead of eight weld nuggets 4 forms circular arc line, and each weld nugget 4 interval on circular arc line is uniformly distributed.
The welding of Qianmen back veneer brace panel and steel pipe adopts 6～8 sections of arc-welding conventionally, and part is elongated, temperature distortion, easily distortion, and size is uncontrollable.By resistance spot welding, on steel pipe and the tangent straight line of part surface, increase solder joint welding, actv. reduces welding stress, and actv. guarantees performance and the functional requirement of part, cuts off the pernicious gas producing because of arc welding, and actv. improves workshop air quality.
