Description

Panel holder for CRT grinding machine {Panel holder of grinding system for CRT}

The present invention relates to a panel holder for a CRT polishing machine, and more particularly, to an improved panel holder used for fixing a panel to be polished in a polishing apparatus used to polish a surface of a CRT panel.

Since the panel of the CRT is made of glass, polishing is performed for surface treatment after molding, and due to the characteristics of the CRT formed so that the surface has a spherical surface, a considerable technical skill is required to polish the surface.

The surface polishing of the CRT panel is completed through three steps. The first polishing is rough polishing using a pad of metal material, the second polishing is polishing using a pad of rubber material, and the third polishing is a nonwoven fabric. Impregnated with urethane resin, it is polished as a pad having a certain elasticity and polished to make it polish.

The polishing apparatus for polishing the panel as described above is provided with a table that is supported by a frame to fix the panel to be polished, and the polishing pad is fixed above the table to be supplied with abrasive and water to rotate by a driving means such as a motor. It is a structure which has a grinding | polishing tool to make.

The table of the polishing apparatus is a panel holder is fixed so that the panel can be fixed in a stable state and rotates at a low speed, and the polishing tool rotates in the opposite direction to the table at a high speed to polish the panel.

The panel holder 1 of the related art fixed on the table to hold the panel has a center ring 3 bolted to the edge of the table 2 and a table 2 inside the center ring 3 as shown in FIG. Independently composed of a disk-shaped spacer (4) which is bolted and coupled.

The center ring 3 and the spacer 4 may prevent damage to the panel 7 on the outside of the core material 5 and the base material 6 made of stainless material in order to maintain the strength and maintain the flatness. It is comprised so that the coating | cover material 8 of a rubber material may be provided.

In the prior art as described above, since the panel holder is dually configured, the cost burden due to the complexity of the production process and the increase of the cost is large, and there are many problems such as disassembling and assembling the centering and the spacer during assembly and disassembly.

Therefore, the present invention is designed to solve the above problems, by providing a panel holder integrated with the centering and spacer to simplify the disassembly and assembly work, and the cost burden due to the simplification of the manufacturing process by molding the same material It aims to contribute to the improvement of overall production and quality following panel polishing.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a perspective view of a panel holder for CRT polishing apparatus to which the technique of the present invention is applied, FIG. 2 is a cross-sectional view of a panel holder for CRT polishing apparatus taken along line A-A of FIG. 1, and FIG. 3 is a line B-B of FIG. Sectional drawing of the panel holder for CRT polishing machine taken along this, FIG. 4 is demonstrated as a state diagram of the use of the panel holder for CRT polishing apparatus to which the technique of this invention was applied.

The polishing apparatus 31 for polishing the panel 30 of the CRT is provided with a table 33 which is supported by a frame 32 to fix the panel 30 to be polished, and above the table 33 a polishing pad. (34) is a structure having a polishing tool (35) rotated by a driving means such as a motor by receiving abrasive and water.

The present invention is characterized by providing an improved panel holder 40 fixed on the table 33 of the polishing apparatus 31 to hold the panel 30 to be polished in a stable state.

The panel holder 40 is;

The center ring 41 and the spacer 42 are integrally formed with a rubber or plastic material having sufficient hardness to prevent damage to the panel 30 formed of glass.

The center ring 41 is formed to protrude upward from the edge of the spacer 42, the upper surface forms a fixing hole 43 for fixing with the table 33 at equal intervals.

The fixing hole 43 is preferably integrally molded by inserting a bushing 44 made of metal so as to improve fixability with the table 33.

A plurality of through holes 45 and 46 are formed in the circumferential direction at the joint portion of the spacer 42 and the center ring 41 so as to easily discharge the abrasive and water introduced for polishing.

The panel holder 40 of the present invention as described above is secured to the table 33 with a bolt through a fixing hole 43 formed in the center ring 41 after being placed on the table 33, the assembly is completed. do.

When fixing the panel holder 40, the panel holder 40, in particular, the center ring 41 may be prevented from being deformed by the bushing 44 made of metal integrally inserted into the fixing hole 43 of the center ring 41. Will be.

In this state, the panel 30 may be placed on the spacers 42 of the panel holder 40, and then polishing may be performed by a conventional method.

When the polishing operation is performed as described above, since the entire panel holder 40 is made of a material which does not damage the glass panel 30 such as rubber or plastic, damage to the panel 30 can be prevented during the polishing process. Will be.

In particular, when the panel holder 40 is to be replaced, the panel holder 40 can be easily removed by releasing the bolts fixing the center ring 41 and the table 33.

The present invention as described above can facilitate the fixing and detaching operation of the panel holder 40 by forming the center ring 41 and the spacer 42 constituting the panel holder 40 integrally, improving the overall productivity and It can contribute to cost reduction.

The present invention as described above provides a panel holder with integrated centering and spacers to simplify disassembly and assembly work, and to form the same material to reduce the cost burden due to the simplification of the manufacturing process. And many other effects that can contribute to quality improvement.
