Abstract
The invention relates to a method for installing and locating a bodywork cavity, aiming at effectively solving the problem of location when the bodywork cavity is installed. The method has the technical scheme that the tail end of a preposed welding part of the bodywork cavity is provided with a boss, and the boss is used for transverse location when a post-positioned welding part of the bodywork cavity is welded with the preposed welding part.
Description
Technical field
The present invention relates to a kind of installation and locating method of bodywork cavity.
Background technology
Body of a motor car is rigidity, the amount of deflection that strengthens certain local location in the process of design in early stage, prevent this regional structure distortion, influences vehicle performance, can be designed to cavity structure, to satisfy bus body strength and collision demand.But consider the spatial constraints of car load configuration design and assembly parts, this cavity structure opening size is often very little, generally between 30mm-70mm, causes can't increasing in the cavity anchor clamps detent mechanism and positions.
In the prior art, bodywork cavity mainly contains following dual mode when installing:
One, as shown in Figure 1, the opening size 58.8mm of floor cavity behind the vehicle body, behind the preorder weldment in front floor crossmember assembly and the postorder weldment back floor pan assembly lap-joint do not consider that X positive direction (laterally) locatees, the back floor pan assembly is poor in X positive direction uniformity in when causing two to cooperate, make the mounting points deviation on this part bigger, cooperate relative position can't guarantee that overlap edge reduces to cause the welding least bit, influence vehicle body precision and welding quality.
Two, as shown in Figure 2, vehicle body is sent out the opening size 33.5mm of cabin cavity, consider that X is to orientation problem, the design turnup structure carries out self-align in lap-joint, but because the single-piece of preorder weldment front windshield crossbeam end plate assembly and postorder weldment front windshield crossbeam upper cover plate assembly is grown (the about 1322mm of single-piece length), and expect thick less (0.7mm), make the stamping parts bounce-back to avoid, when causing assembled in situ, overlap edge to X to folk prescription to self-align inefficacy, cause relevant mounting points X poor to the precision uniformity, influence the assembling of front windshield and gutter channel, have the risk that fit clearance is uneven and leak to reaching Z.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of installation and locating method of bodywork cavity, the orientation problem in the time of can effectively solving the bodywork cavity installation.
Realize the object of the invention technical scheme:
A kind of installation and locating method of bodywork cavity is characterized in that: the tail end of the preorder weldment of bodywork cavity is provided with boss, when the postorder weldment of bodywork cavity and the welding of preorder weldment, carries out located lateral by this boss.
The preorder weldment can be front windshield crossbeam end plate assembly.
The postorder weldment is a front windshield crossbeam upper cover plate assembly.
The preorder weldment can be back front floor crossmember assembly.
The postorder weldment is a middle back floor pan assembly.
The boss height is 8-12mm, and preferred height is 10mm.
The beneficial effect that the present invention has:
The present invention is provided with boss at the tail end of the preorder weldment of bodywork cavity, when the postorder weldment of bodywork cavity and the welding of preorder weldment, carries out located lateral by this boss.
1, increases the positioning boss structure, can effectively solve the cavity structure folk prescription, guarantee the uniformity of vehicle body mounting points, avoid lap-joint to produce least bit weldering, influence body quality to the problem that can't locate.
2, increase the positioning boss structure, play the effect of strengthening than big stamping parts, can effectively strengthen the intensity of stamping parts, avoid the stamping parts bounce-back and cause self-align Problem of Failure, more help stamping parts forming surface precision.
3, increase the positioning boss structure, when doing impact test, this structure can realize the effect of energy-absorbing and buffering, and is favourable to impact test.

Fig. 2 sends out cabin cavity scheme of installation for existing vehicle body;
Fig. 3 is floor cavity scheme of installation behind the vehicle body of the present invention;
Fig. 4 sends out cabin cavity scheme of installation for vehicle body of the present invention.
The specific embodiment
Embodiment 1:
As shown in Figure 3, base plate 2 welding in back constitute floor cavity behind the vehicle bodies in preorder weldment when operation (split elder generation weldment) back front floor crossmember assembly 1 and the postorder weldment (weldment after when splitting operation).Tail end at back front floor crossmember assembly 1 is provided with boss 3, the boss height is 8-12mm, and preferred height is 10mm, and base plate 2 carries out laterally (X folk prescription to) regulation location after this boss centering, avoid back base plate 2 play on directions X, guarantee the uniformity of two cooperations.
Embodiment 2:
As shown in Figure 4, floor cavity behind preorder weldment (elder generation's weldment when splitting operation) front windshield crossbeam end plate assembly 4 and postorder weldment (weldment after when splitting operation) the front windshield crossbeam upper cover plate assembly 5 welding formation vehicle bodies.Tail end at back front floor crossmember assembly 1 is provided with boss 6, the boss height is 8-12mm, preferred height is 10mm, this boss carries out laterally (X folk prescription to) regulation location to front windshield crossbeam upper cover plate assembly 5, avoid front windshield crossbeam upper cover plate assembly 5 play on directions X, guarantee the uniformity of two cooperations.
Claims (7)
