Detailed Description
The following description of the preferred embodiments of the present invention will be made in further detail with reference to the accompanying drawings.
As shown in the figures 1-6, in the new energy commercial vehicle side wall skin installation structure, the periphery of a skin 4 is bonded with a vehicle body framework 1 and then riveted, the middle of the skin 4 is bonded with a section bar of the vehicle body framework 1, and the periphery of the skin 4 is connected with the riveted part of the vehicle body framework 1 through a sealant. The skin 4 is sent to a workshop after a supplier finishes spraying surface paint, and then the skin 4 is directly arranged on the car body framework 1 which is welded and coated with PVC for assembly. After the periphery of the skin 4 is bonded with the vehicle body framework 1, the periphery of the skin 4 is riveted with the vehicle body framework 1; the large surface of the middle part of the skin 4 is connected with the section bar of the vehicle body framework 1 through structural adhesive; and after the periphery of the skin 4 is riveted, the sealant is smeared to carry out waterproof sealing on the rivet and the periphery of the skin 4, so that the reliable installation and sealing of the skin 4 are realized.
The skin mounting structure realizes the reliable mounting of the skin 4, so that the cost of the skin 4 needs about 1000 thousands according to the traditional side wall outer plate (with the length of 3 meters and the width of 1.4 meters) without newly opening a stamping die. And use the utility model discloses a novel aluminium covering 4 need not open the mould, only need carry out the hem on the flanging machine all around, and the riveting hole can accomplish processing through laser. At the same time, the skin 4 is reduced in weight by about: 10.2Kg (the length of one side of the skin 4 is 3 meters, the width is 1.4 meters, the thickness is 0.7mm, the material is steel, and the material is aluminum with the thickness of 1.5 mm). Such a skin mounting structure contributes to weight reduction of an automobile. The skin 4 is connected with the aluminum framework after paint spraying, so that the electrophoretic painting and paint spraying process of the white automobile body can be omitted, the production process is simplified, and the investment is saved.
The periphery of the skin 4 is provided with a flanging, and the skin 4 is riveted with the vehicle body framework 1 through the flanging. The flanging of the skin 4 can be obtained by flanging on a flanging machine, and the processing technology is simple and low in cost.
Riveting holes are formed in the flanging of the skin 4 and are evenly distributed on the flanging. The riveting hole can be realized by laser, and the processing technology is simple and the cost is low. And a skin mounting rivet 2 is arranged on the riveting hole of the skin 4, so that the reliable fixed connection of the skin 4 and the vehicle body framework 1 is realized.
The skin 4 is made of aluminum and has a thickness of 1.2-2.0 mm.
The middle part of the skin 4 is connected with the section bar of the vehicle body framework 1 in a bonding way through structural adhesive. The skin 4 is connected with the section bar of the vehicle body framework 1 by the structural adhesive, so that the skin 4 is reliably fixed, the structural adhesive bonding process is easy to realize, and the method is convenient to operate and low in cost.
The utility model discloses new forms of energy commercial car side wall covering mounting structure's installation step does:
a. coating glue on the position of a glue coating line on the vehicle body framework 1;
b. skin 4 positioning and placing: the positioning pin is aligned with the positioning hole 6 and pressed to the bottom; then, the skin 4 is smoothed from the positioning side without being directly placed on a vehicle body, so that the skin 4 is placed in place at one time;
c. bonding of the skin 4: the manual pressing + the tool pressing: and bonding the skin 4 at the gluing position with the vehicle body. If the skin 4 is not attached to the vehicle body, the attachment is ensured by tensioning with paper tapes or pressing with heavy objects; if the hole can not be attached yet but the gap is less than or equal to 3mm, the hole is fixed by a rivet, otherwise, the installation is suspended; note that the operation time of b and c is within 8 min;
d. riveting a skin 4: drilling and riveting while maintaining the compression during bonding: riveting the rivet hole I7, the rivet hole II 8, the rivet hole III 9 and the residual rivet holes in sequence from front to back and from top to bottom; abnormality such as rivet stripping, skin 4 damage and the like should be avoided in drilling and riveting;
e. removing excessive glue and checking: removing the overflowing glue (including the mounting hole) during the bonding process; checking riveting omission and whether the skin 4 has tilting interference (the clearance is less than or equal to 3 mm);
f. coating a sealant: removing debris generated during installation; checking the gluing quality after finishing; and finally tearing off the protective film.
The new energy commercial vehicle side wall skin mounting structure can not only realize reliable mounting of the skin 4, but also has the advantages of low structure cost, simple mounting process, convenient operation, contribution to vehicle cost control and realization of benefit maximization.
Obviously the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial improvements made by the method concept and technical solution of the present invention are all within the protection scope of the present invention.
