Background

The coating auxiliary tool is also called a coating tool, a jig, a clamp and a limiting tool. The coating auxiliary tool is an auxiliary tool which plays a role in ensuring coating quality, improving production efficiency, making up design defects to a certain extent, reducing labor intensity of staff and reducing coating cost in the whole process of coating the automobile body. Any procedure in the coating process can not leave a corresponding auxiliary tool, and the reasonable design of the coating auxiliary tool is very important.

The automobile front cover has large area and mass, and particularly, the front cover made of steel is easy to deform, air bags, bump damages and the like in the coating process. This patent is to pretreatment electrophoresis process, has expounded a utensil is assisted with spacing vapour bonnet of five points to application, can avoid the colliding with of vapour bonnet in the application process completely and injure and the deformation problem.

The existing automobile front cover auxiliary tool is diversified, can be divided into a single-point auxiliary tool, a two-point auxiliary tool and a three-point auxiliary tool according to the number of limiting points, has different forms, and plays a role in supporting and fixing the front cover in the pre-treatment electrophoresis process.

The existing auxiliary tools for coating the automobile front cover have similar basic functions, but have larger structural difference, so that the performance difference is larger, and the following types are mainly adopted:

1) the supporting points of the auxiliary tool are less than three, if the front cover is large and heavy, and the inner plate reinforcing structure has defects, the front cover is deformed in the coating process, the deformation is often greater than 5mm, and the repair cannot be performed.

2) Assistive device top is directly hooked on the protecgulum inner panel, but does not lock, and the protecgulum can appear the displacement at "Z direction" relative assistive device, leads to easily assisting the utensil slippage in the locating hole of protecgulum inner panel, finally leads to the protecgulum to collide with the wound, does not consider the protecgulum deformation problem.

3) The top end of the auxiliary tool is directly hooked on the inner plate of the front cover, and the auxiliary tool and the inner plate of the front cover are stressed and deformed due to the pressure of the pretreatment electrophoresis tank liquid, so that the auxiliary tool is difficult to repair.

4) The top end of the auxiliary tool is connected with the front cover latch hook and is not locked. Not all car enterprises have the hasp in the design protecgulum, and current patent is not suitable for the protecgulum structure that does not have the hasp.

The existing auxiliary tool for coating the front cover of the automobile approximately has the following defects: firstly, the front cover of the automobile is easy to deform in the coating process, particularly for the automobile with a large and heavy front cover, the middle of the front cover is high and the two sides are low easily caused by using a single-point support auxiliary tool, the middle of the two sides is high and the middle is low easily caused by using a two-point support auxiliary tool, and the two sides of the front cover are low possibly caused by using a three-point auxiliary tool; secondly, the auxiliary tool is directly contacted with the inner plate of the front cover, and the contact position of the inner plate of the front cover and the auxiliary tool is easy to deform under the pressure action of the pretreatment electrophoresis tank liquid; the auxiliary tool is not firm in limiting, the front cover still has certain movement in the Z direction in the tank liquor, and the front cover is possibly collided with the front fender to cause gouge in the falling process; the auxiliary tool is not locked with the front cover, the front cover is in a free floating state, and although the air bag of the inner plate of the front cover can be reduced, the probability of collision between the inner plate of the front cover and the front fender or the probability of collision between the inner plate of the front cover and the auxiliary tool is greatly increased.
