Abstract

PURPOSE:To enable complete work from cutting, grinding to finishing with single machine, by grinding/polishing a mirror material board sucked to a holding chip by means of a machining wheel while advancing the holding chip coupled to a sucking machine straight over a horizontal frame. CONSTITUTION:A mirror material board 6 is fed straight horizontally by means of a conveyor device 1 mounted with a holding chip 12 nd sequentially subjected to various grinding by means of various wheels 3 arranged above a row of holding chips 12, so as to take out finished rear view mirrors sequentially from the other end. When the mirror board is fed simply to the feeding section, finished rear view mirrors can be taken out automatically from the opposite end, thereby manpower is not required and the production speed can be improved remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rearview mirror polishing machine for finishing rearview mirrors used in automobiles by grinding and polishing.

A cut glass plate cut into the shape of a rearview mirror (
This is a machine that feeds a mirror blank plate (hereinafter referred to as a mirror blank plate) to a machine and cuts, grinds, and polishes the surface to finish a rearview mirror (into a prism shape).

By the way, conventional rearview mirror grinding and polishing are usually performed using at least two types of machines as follows.

That is, first, a mirror blank plate is cut into a prism using a cutting machine. Next, the material is put through a grinding machine and a polishing machine, where it is moved in a lapping manner while being supplied with an abrasive material, and is then ground and polished to finish it.

The above-mentioned cutting machine usually uses a surface grinder equipped with a horizontal rotating surface plate and a cutting head equipped with a cup tie N-ear wheel mounted facing the rotating surface plate. In this machine, a glass plate, that is, a plurality of mirror blanks, is fixed to a cassette 1~, and this cassette is placed on the above-mentioned rotating surface plate.While rotating this surface plate, the above-mentioned Prism cut with cup diamond. The cut mirror blank is taken out together with the cassette, and while it is still in the cassette 1, it is fed to the rotating surface plate of the next grinding and polishing machine with the mirror blank facing down, and the cassette side is applied with low pressure from above. Wrapping and polishing work is done under pressure to improve the quality.

By the way, with the conventional processing method as described above, cutting, grinding, and polishing must be performed in separate machines.

This is a labor-intensive and impossible rate. Production speed is slow.

SUMMARY OF THE INVENTION Therefore, the present invention provides a rearview mirror grinding and polishing machine that can perform all processes from cutting and grinding to polishing in a single machine.
