Embodiment

[0056] Example: refer to figure 1 Shown, a kind of bus FRP side skin assembly method comprises the following steps:

[0057] Step 1) Preliminary preparation: determination of body side frame material and surface treatment method, as well as selection of structural adhesive, primer, and cleaning agent;

[0058] 1) All bonding surfaces are required to be electrophoretic coating (ordinary square steel side frame electrophoresis), aluminum profile side frame, stainless steel side frame;

[0059] 2) Adhesive and strength tests for adhesive glue, primer, and cleaning agent used for bonding FRP side skins. According to the results, select ISR7003 sskf, ISR7005 sskf, ISR7008 AP Boss structural adhesive, Primer N41, Primer M, TS5028 primer, and industrial alcohol as cleaning agent;

[0060] 3) When the selected adhesive, primer, and cleaning agent are used for the bonding surface, all of which require electrophoretic coating (electrophoresis of the side frame made of ordinary square ...

Abstract

The invention discloses a glass fiber reinforced plastic side skin assembly method for a public transportation bus. The glass fiber reinforced plastic side skin assembly method comprises the followingsteps that step (1) preliminary preparation is performed, specifically, the material and surface treatment method of a skeleton of a body side are determined, and selection of structural adhesive, primer coat and cleaning agent is performed; step (2) pre-assembly of glass fiber reinforced plastic side skins of left and right side bodies is performed; step (3) preparation of a working environmentbefore bonding is performed; step (4) skeleton verification and cleaning of glass fiber reinforced plastic skin bonding surfaces and body side skeleton bonding surfaces are performed; step (5) glue operation is performed; step (6) glass fiber reinforced plastic skin assembly and clamping and fixing are performed; step (7) glue filling and residual glue cleaning are performed; and step (8) exteriortrim mounting hole opening and trimming are performed. The glass fiber reinforced plastic side skin assembly method for the public transportation bus has the advantages that the raw material waste caused by replacing side skins can be effectively reduced, the time for replacing the side skins is shortened, the cost for replacing the side skins is reduced, the physical harm to operators during operation is reduced, the pollution to the environment is reduced, the range of stress distribution between the skins and the body skeleton is reduced, and noise is reduced.

Description

technical field [0001] The invention relates to a method for assembling the FRP side skin of a bus. Background technique [0002] At present, the side skin materials of domestic buses are mostly galvanized sheets, and some vehicles also have aluminum sheets, and the assembly process is mainly welding. If this kind of assembly process has deformations such as small-scale collisions and weld cracks during the operation of the vehicle, it is often necessary to replace the entire side skin or most of the side skin of the vehicle body during maintenance, and dynamic welding (welding) When removing part of the interior, exterior, skin inner heat insulation material). The waste of raw materials for replacing the side skin is serious, time-consuming, and costly, and there are welding dust particles, harmful gases, arc radiation, and noise during the welding process, which is harmful to operators and the environment. Contents of the invention [0003] The purpose of the present i...
