Abstract

PURPOSE:To attempt both high efficiency and high precision of work with feasibility of simultaneous machining on both plane surfaces and side surface of a workpiece, by employing a pair of rollers arranged at an interval narrower than the diameter of the workpiece to machine the side surface thereof and a pair of rotary discs for machining parallel plane surfaces thereof in a direction suitable for pushing the workpiece toward said rollers. CONSTITUTION:When rotary discs 7, 8 are turned in directions (a) and (b) respectively, a glass plate 1 moves in C direction along a vertical bisector L due to the frictional force given from polishing cloth 11, 12 and reaches a position where it touches rollers 2, 3 and a supporting blade 13. Therefore, if the rollers 2, 3 are turned in directions (d) and (e) respectively, the glass plate 1 makes self-rotation in (f) direction. Hereat, the frictional force between the glass plate 1 and roller 3 is larger than that between the same plate 1 and roller 2, consequently the glass plate 1 makes no slip against the roller 3. Therefore, slipping takes place between polishing cloth 6 and the side surface of the glass plate 1 by setting the numbers of revolution of roller 2 and 3 respectively. Thus, polishing of the side surface can be carried out with high efficiency and high precision simultaneously with polishing of parallel planes with polishing cloth 11, and 12 by suppling polishing agent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a multi-surface simultaneous processing device, and more particularly to a multi-surface simultaneous processing device that simultaneously processes the flat surface and side surface of a workpiece having a pair of parallel planes with high efficiency.

[Prior art]

In optical devices, so-called plane-parallel glasses, which have a pair of parallel planes, are often used.

Considering the intended use of this mechanical parallel plane glass, it is sufficient to form only parallel planes as optical surfaces, and there is no need to form side surfaces as optical surfaces. From Shigashihiko, for example, when used as an optical component for a high-output laser device, if the optical component is distorted or cracked, it may break during use.

For this reason, it is necessary to polish the side surfaces of parallel plane glass used in laser devices and the like.

Conventionally, such side surface polishing of parallel plane glass was performed in a separate process from plane polishing.

For this reason, multiple processing devices and multiple processes are required, and the processing time is long, causing an increase in costs.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, it is an object of the present invention to provide a multi-face simultaneous processing device capable of simultaneously performing plane processing and side processing of a workpiece having a pair of parallel planes.

A pair of first driving bodies are arranged at an interval narrower than the diameter of the workpiece, and the driving bodies are driven and rotated while contacting the gA1 surface of the workpiece, and at least one of the first driving bodies is driven to rotate. A means for machining the side surface of the workpiece is provided at the contact portion with the workpiece, while the workpiece is brought into sliding contact with the pair of parallel planes of the workpiece. A pair of second driving bodies are arranged to be driven and rotated in the direction of pressing against the first driving body, and the driving bodies have a parallel plane of the workpiece in sliding contact with the workpiece. υ is achieved by a multi-face simultaneous processing device characterized by having a processing means for processing.

[Embodiments of the invention]

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a schematic side view (partial view) of a multi-surface simultaneous polishing device which is an embodiment of the multi-surface simultaneous processing device of the present invention, and Fig. 2 is a schematic plan view of the main parts thereof. . In the figure, 1 is a circular parallel plane glass plate which is a workpiece.

The glass plate 1 is previously formed to a size that allows for a polishing margin.

A pair of rollers 2 and 3, which are first driving bodies, are arranged on both the left and right sides of the glass plate 1. The pair of rollers 2 and 3 are arranged at a spacing slightly narrower than the diameter of the glass plate 1, and are each driven by a motor 4.5 to rotate in the direction of the arrow. A polishing cloth 6, which is a means for polishing the side surface of the glass plate 1, is attached around one roller 2. Further, the other roller 3 is in contact with the glass plate 1 in such a manner that it does not damage the side surface of the glass plate 1. As the roller 3, for example, one using a hard roller is used.

A pair of rotating plates 7 and 8, which are second driving bodies, are arranged on both upper and lower sides of the glass plate 1. This pair of rotating plates 7, 8
are arranged so that a part of their outer peripheral parts are parallel to each other and face each other, and are driven and rotated in the direction of the arrow by motors 9 and 10, respectively. On the outer periphery of the rotary plate 7.8, a polishing cloth 11, which is a means for polishing the glass plate 1, is arranged in a ring shape with the width of the back corresponding to the portion facing the glass plate 1. 1
2 is installed. Further, a support blade 13 for positioning the glass plate 1 is disposed at a position facing the side surface of the glass plate 1. The supporting blade 13 may be made of, for example, hard rubber. In addition, 14 is a polishing side supply means.

The operation of the multi-surface simultaneous polishing apparatus as described above will be briefly explained with reference to FIG. First, along the perpendicular bisector of a straight line connecting the centers of rollers 2 and 3,
3 and the support blade 13 (position A in FIG. 3), the glass plate 1, which is a workpiece, is placed between the rotary plates 7 and 80. Next, when the rotary plates 7 and 8 are rotated in the directions of arrows a and b, the glass plate 1 is moved along the perpendicular bisector in the direction of arrow C by the frictional force with the polishing cloths 11 and 12, and the roller 2.3 and support blade 13
(position B in FIG. 3).

Therefore, when the rollers 2 and 3 are driven to rotate in the directions of arrows d and e, respectively, the glass plate 1 rotates in the direction of arrow f. Here, as shown in the figure, the support blade 13 is arranged obliquely to the perpendicular bisector line, and the tangent to the outer circumference of the roller 3 at the point of contact between the roller 3 and the glass plate 1 is exactly It is turned so that it is perpendicular to the cutting edge of the supporting blade 13, so that the roller 2 of the glass plate 1
The frictional force between the glass plate 1 and the four-layer 3 is greater than the frictional force between the glass plate 1 and the four-layer 3. Therefore, the glass plate 1 rotates with almost no slippage with respect to the roller 3. Therefore, roller 2
and 30 rotations, respectively, so that the abrasive cloth 6 attached to the roller 2 does not lubricate the side surface of the lath plate 1. Therefore, as shown in FIG. 1, by supplying the abrasive from the abrasive supply means 14, the flat surface of the glass plate 10 is polished by the polishing cloths 11 and 12, and at the same time, the polishing cloth 6 is It is possible to perform a polishing process on the side surface of the blade 2 plate 1.

In the above embodiment, a specific example of polishing is shown, but grinding or lapping can be performed in the same manner. In the case of grinding, attach a diamond tool, for example, to the edge of the abrasive cloth by supplying grinding fluid to the edge of the abrasive, and in the case of lapping, attach a lapping plate, for example, to the edge of the abrasive cloth, υ. All you have to do is supply the abrasive grains to the abrasive.

Further, in the above embodiments, a specific example is shown in which the shape of the side surface of the glass plate 1 is cylindrical, but by appropriately deforming the longitudinal cross-sectional shape of the rollers 2 and 3, Products with various side shapes can be obtained.

Further, in the above embodiments, the case where the workpiece is glass is illustrated, but it goes without saying that the processing apparatus of the present invention can also process workpieces made of ceramic and various other materials.

〔Effect of the invention〕
