Description

Door fixtures used for painting cars

The present invention relates to a door fixture used when opening or closing the door at a predetermined interval from the body during the painting work of the vehicle, and more specifically, it is applied by configuring the door fixture used in various kinds of painting processes in one kind. Therefore, the present invention relates to a door fixture used for painting a vehicle to improve productivity by further improving workability and reducing manufacturing costs due to unnecessary process reduction.

In general, the body of an automobile is composed of several panels assembled, and in order to make a body, first, a material cutting process of cutting a rolled copper plate into sizes easy to process on each part of the vehicle is performed. It consists of a press-processing process for forming parts and a vehicle body process for welding molded panel parts in the form of a vehicle body using a large multi-spot welding machine or a robot.

And the vehicle body is assembled as described above is cleaned and then the coating is the purpose of the coating is to protect and improve the appearance of the object and maintain and maintain a high level of characteristics of the product is required. In particular, the exterior coating quality of the vehicle body needs to maintain its aesthetics by maintaining no gloss or color of the coating film even if it is used for a long time.

The basic process of this coating is the three-time painting of the primary coating (electrodeposition), intermediate coating, and finishing painting. The process between the primary coating and the intermediate coating is a process such as sealing, soundproofing, and undercoat for rust prevention. As a painting, there is also a multilayer coating.

In addition, automotive paints used for painting can be classified into electrodeposition paints, intermediate paints, finish paints and plastisol-based paints. Electrodeposition paints are improved as an important factor that affects the surface gloss after initial painting due to the rust prevention of the body. Have been. Intermediate paints also have a surface-adjusting element of the finish paint, but there are also active uses as a substitute for the primary paint, such as black and color sealers for the chassis. In addition, there are many practical examples of the prime paint, which is applied with the latest colors according to the times, and the surface, excellent gloss, and mica paint with bright materials.

In this coating, pretreatment is a process of forming a chemical film on the surface of the vehicle body and the surface of the inner panel to maintain the adhesion to the rust preventive or electrodeposition paint. It has been widely used in the initial coating of automobile bodies for reasons such as quantitative management by conditions, good adhesion to shade parts, and low paint loss.

That is, the car body passing through the drying furnace of the pretreatment process enters the electrodeposition tank at an angle by the conveyance of the overhead conveyor, whereby air sticks or bubbles are removed to form an electrodeposition film that is the basis of rust prevention on both the outer surface and the inner surface. After that, the residue of the electrodeposited membrane is washed with ultrafiltration (UF) solution, and then washed with a dip and sent to a baking step.

The intermediate coating film is interposed between the primary coating and the finishing coating, and has functions such as adhesion, pitching resistance, smoothness, and weather resistance with both sides, and in particular, for chipping resistance, the stone guard coat (SGC) is used depending on the used part and required performance. ) And anti-chipping coat (ACC). In addition, two-layer paint, color paint, and gray paint are aimed at improving appearance quality.

In addition, the intermediate coating process includes cleaning to remove various defects such as dust and foreign matter on the base (electrodeposition) coating; A spray that makes the paint thinner by pneumatic or rotary centrifugal force or the like and adheres to the workpiece; A setting for evaporating the solvent in advance and sufficiently mixing the atomizing paint in order to prevent soot due to rapid solvent evaporation upon baking; It consists of four parts of the baking which dries paint.

The facility is maintained at a constant temperature and humidity in order to stabilize the state change of the paint (atomization → adhesion → coating), and to quickly remove the atomizing paint that does not adhere to the intended coating, and to prevent adhesion to other coating. Spray booth to maintain the working environment; A paint supply device for supplying paint diluted with proper conditions from a tank to a spray booth through a pipe by a pump; Soburowa; There are spray equipment and automatic coating machine.

In addition, the finish is to protect the body aesthetics, and the aesthetics include metallic colors that give a metallic luster by combining solid colors that produce various colors by the characteristics of pigments and coloring pigments and alumin flakes. The finish coating film should have the role of protecting the functional coating film (electrodeposition, intermediate coating, etc.) from ultraviolet rays, and the performance of the finish coating film itself in weather resistance or stain resistance.

On the other hand, in the coating work as described above, conventional door fixtures are used according to each process, which includes pre-treatment / electrodeposition, sealing and middle / top coat, and middle / top coat robot interior coating. .

In other words, the pretreatment / deposition was made by operating a door fixture having a structure that can open and fix the door about 10-15 cm from the body so that the pretreatment liquid and the electrodeposition material can easily flow into the body. Top coat is manufactured and operated in different structure to prevent contact between door and body during sealing and middle and top coat painting work. It was built and operated in another structure to prevent it from happening.

Therefore, by manufacturing and operating a separate door fixture according to each process, the manufacturing cost is increased by using a plurality of tools, there is a problem that the workability is degraded due to the complexity of the work process and eventually the productivity is lowered.

Therefore, an object of the present invention is to solve the above problems, the operation of various processes, such as when the door is opened or closed from the body when painting the car, or to avoid the interference of other parts or tools. It is to provide a door fixture that is used for the painting work of the vehicle to achieve the effect of improving the workability according to the shortening of the work process, and the productivity improvement according to the reduction of the manufacturing cost by easily performing a single door fixture.

The object of the present invention is to construct a door fixture used for the painting work of the vehicle, one side of the upper surface of the body is configured with a locking portion at one end and the handle is configured at the other end, between the locking portion and the handle is formed fasteners The pin is installed so that it can be rotated, and the other side of the upper surface of the body to form a latch for fixing the handle of the fastener, the bottom side of the body is formed with a support piece with the insertion portion, the other side of the bottom and the protrusion It is achieved by configuring a ruler piece formed with a ruler groove to lubricate the fixture.

In the present invention, in the process of painting a car, the door is opened or closed from the body when the door is not used, without using a separate door fixture, as a single door fixture to be used in common in various processes work process The above object can be attained because it can be expected to reduce the workability, improve workability, reduce manufacturing cost and improve productivity.
