Problems solved by technology

[0017] Generally speaking, due to the high density of the galvanized steel sheet, the current method is labor-intensive for the operator, and requires more operators to cooperate more tacitly; and, due to the increase in the number of operators, it is divided into several steel plates that are welded separately. It is likely that due to improper operation, the appearance often has uneven appearance; the welding of multiple steel plates also increases the repetitive workload of multiple welding, and the welding of multiple skins also has many times and extremely high precision cutting and later docking. High precision operation requirements, due to the lack of proficiency of any steel plate operator, may cause rework of the entire vehicle skin, greatly increasing the cost

Embodiment Construction

[0040] Taking a passenger car with a length of 10m and a width of 2.2m as an example, the skinning operation method is introduced in detail:

[0041] (1) Use an angle grinder to remove the paint film, scale, rust, etc. on the upper surface of the roof frame, and use compressed air to blow off surface impurities and dust.

[0042] (2) Clean the upper surface of the entire roof frame with CH-M1 cleaner produced by Yangzhou Chenhua Technology Group Co., Ltd.

[0043] (3) Apply primer (Huitian HT906G type) on the upper surface of the longitudinal beams on the outermost sides of the roof frame.

[0044] (4) Paste the cut (15mm×15mm×2mm) damping plate pads on the middle position of the upper surface of the longitudinal beams on the outermost sides of the roof frame, and the distance between the damping plate pads is 300±10mm.

[0045] (5) After confirming that the bonding surface (upper surface of the roof frame) is free of water and moisture, and the cleaning agent and primer are ...

Abstract

The invention provides a new material applied to manufacturing top skin for a passenger car. Glass reinforced plastics is adopted to serve as the new material of the top skin. The whole skin is formed at one time without welding or steel plate splicing. The method has the advantages of being easy to operate, low in labor intensity, attractive in appearance and light in density and reducing the total weight of a car body.

Description

technical field [0001] The invention relates to the field of passenger car roof assembly, in particular to a processing method for using a whole piece of glass steel plate as the roof skin of a passenger car. Background technique [0002] At present, the top skin of a bus is usually made of galvanized steel sheet, which is spot-welded on the top frame in two or three pieces. The specific steps are as follows: [0003] 1. Push the vehicle to be skinned into the station; [0004] 2. Grinding the parts of the top frame that need skin spot welding; [0005] 3. Remove the oil and dirt and roll the skin material that has been lowered and leveled according to the size of the drawing; [0006] 4. Lift and place the roof; [0007] 5. Apply black sealant on the non-spot welded skeleton of parts and skeleton; [0008] 6. Unroll the skin, flatten it, and align the skeleton; [0009] 7. The front end of the skin is spot welded firmly; [0010] 8. The rear end of the skin is tighten...
