Description

Car Polisher {Car Polisher}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle polisher, and in particular, the present invention relates to a vehicle polisher for use in polishing and polishing a coating film surface of a vehicle body exterior.

In general, in order to clean the exterior of the car body to clean the car wash after washing with water, to protect the surface of the body by applying a wax (wax) to clean the paint surface is a general coating surface management method.

This is only when the state of the painted surface is somewhat good by waxing, and when the scratch is severely scratched or contaminated by various contaminants, the painted surface is polished to smoothly polish the wounded surface (polishig). shall.

In order to smoothly polish (scratch) the damaged painted surface, the repair shop or the specialty shop performs polishing work by attaching a polishing pad to the mobile grinder motor. In this case, the body surface is divided into 50cm * 50cm and set as one work section. After each work section, compound (gloss for polishing) is applied and polished. Since the compound in the section is consumed, the work is stopped and the compound is sprayed in the next work section.

In this way, it is possible to improve the efficiency of polishing work by improving the intermittent polishing work by improving the intermittent polishing work, and also to increase the rotational speed of the polishing machine, the size of abrasive particles, and the polishing pressure working time on the pad during polishing work with the polishing machine. As the temperature of the vehicle body surface increases, in this case, as shown in FIG. 1, when the temperature rises above the limit temperature, bending occurs on the paint surface due to thermal expansion of the paint surface, resulting in irregular deformation of the paint. When the surface is polished by a polishing machine, when the surface of the body is cooled after the work, as shown in FIG. 2, the surface of the body has an irregular surface, which causes diffused reflection of light, resulting in a drop in the degree of gloss. The temperature of the cotton is continuously informed to the worker, so Complement the problem is to obtain a high quality gloss stably.

The present invention is to solve the conventional problems as described above, in order to polish the surface of the vehicle body, the abrasive or varnish is sprayed automatically so that the continuous efficient operation without the manual application of the abrasive or varnish manually The purpose is to provide a vehicle polisher with a function.

Another object of the present invention is to provide a stable gloss by notifying the operator continuously the temperature of the gloss working part during the operation to prevent errors during the gloss operation.

The vehicle polisher according to the present invention for achieving the above object is coupled to a motor housing with a built-in drive motor that rotates by receiving power from a power supply unit, and a polishing pad and a polishing pad to transfer rotation from the driving motor and abrasives.

The vehicle polisher according to the present invention made as described above, in polishing the surface to polish the vehicle surface paint, does not apply the polish or the abrasive manually, and the abrasive spray motor on / off switch is automatically applied to the surface of the vehicle. Since the coating amount of the varnish to be sprayed can be adjusted, continuous polishing can be performed, and the efficiency of the polishing can be improved.

In addition, since a large number of abrasives can be separated and contained in a single container, not only the efficiency of the work can be achieved, but also the temperature of the vehicle body surface is sensed during the polishing operation, and when the temperature rises above the threshold temperature, the alarm is alerted. Because of this function, stable work can be performed.

For the preferred embodiment of the present invention, it is necessary to familiarize with the glossy elements of the vehicle, among which the important elements are as follows.

The first factor is the number of revolutions of the gloss pad. Normally, the speed of rotation is controlled between 1400 and 2300 rpm depending on the condition of the body surface and the particles of the polishing agent used for polishing.

The second factor is the size of the particles of the polish or abrasive.

Kind of polish
(according to mesh)
Usage
1500 mesh or less
Primary polishing compound used when the surface is heavily soiled or relatively scratched

1500 mesh or more and 2000 mesh or less
Secondary polishing compound used when the painted surface is relatively less contaminated or there are fine scratches

More than 2000 mesh Less than 3000 mesh
Compound used for minor stains or fine scratches on painted surfaces and used for tertiary polishing

More than 3000 mesh
Compound used for the final finishing of polishing work as a compound for 4th polishing

The table describes the use of the varnish according to the particle size. Mesh is a unit which shows the size of particle | grains, such as a powder, and is a unit generally represented by the number of meshes between 1 inch of a sieve.

The thinner the particle, the lower the pressure applied to the surface of the vehicle body, but the lower the temperature that must be limited to prevent deformation of the paint painted on the vehicle body surface.

Kind of polish

Pressure on the body surface
Limit temperature
Rpm
1500 mesh or less

10 kg
60 ℃ or less
2000 to 2300 rpm
1500 mesh and above 2000 mesh

8 kg
50 ℃ or less
1800 to 2000 rpm
2000 mesh and above 3000 mesh

6 kg
50 ℃ or less
1600 to 1800 rpm
More than 3000 mesh

5 kg
40 ℃ or less
1400 to 1600 rpm

The third factor is the working pressure on the surface of the car body. At 1500 mesh or less, scratches are removed using wool pads or sponge pads, and the surface of the car body is polished until the painted surface becomes flat.

The fourth element is the temperature of the painted surface painted on the car body. As shown in Table 2, each polish has a limit temperature at which the bending due to thermal deformation of the paint surface does not occur. Otherwise, the heat deformation of the surface of the paint occurs and the paint is irregularly deformed, and when the irregular surface is polished with a polishing machine, the surface of the vehicle body is irregular as shown in Fig. 2 even when the body surface is cooled after the operation. There is a problem in that the diffuse reflection of the light occurs to have a degree of gloss or the scratch occurs. As such, the biggest problem when performing continuous polishing or polishing operations using the vehicle polisher according to the present invention is the heat generated during the operation (the frictional heat between the pad and the surface of the vehicle and the frictional heat between the polish or the abrasive and the surface of the vehicle) to be. One of the basic elements of a polisher for a vehicle is to measure and display the heat generated during the polishing operation continuously, and when the temperature is higher than the reference temperature, the warning sound and the red warning light are turned on to operate only within the reference temperature range during the operation.

Finally, the fifth factor is the speed at which the polisher reciprocates the body surface. There is nothing fixed, and it should be judged by seeing the degree of gloss with the naked eye. Scratch is likely to occur when the reciprocating speed is increased in the finishing operation of the thinner particles.

As described above, the efficiency of the work is also required for the gloss of the vehicle, but it is important to keep the temperature of the surface of the vehicle below the limit temperature during the operation, depending on the type of polish or abrasive.

An example of the operation of the vehicle polisher is as follows.

First, the maximum working limit temperature, the rotational speed of the polishing machine and the injection amount of the abrasive are set according to the type of polishing operation. After the start of work and when the temperature of the working vehicle surface reaches the limit temperature measured by the temperature sensor, alarm sound occurs, stop work on the part and change the work range to another part.

In the above, a preferred embodiment of a vehicle polisher according to the present invention has been described, but the present invention is not limited thereto, and various modifications can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. This also falls within the scope of the present invention.
