Polishing oil pan of centripetal polishing machine

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centripetal polishing machine for polishing an optical lens, and more particularly, to abrasion oil receiving of a centripetal polishing machine to easily collect and drain the abrasive oil provided in the aperiodic polishing machine and to install pipes and wirings concisely. It is about.

In general, lenses used in optical devices such as cameras, compact disk drivers, facsimile and sights, endoscopes, telescopes, etc., generally rough-cut materials of a predetermined size. It is manufactured through the process of grinding | polishing, ie, grinding | polishing which finishes processing and refines the surface.

Such a polishing process includes a polishing process of grinding a lens as a polishing machine after cutting and rough-cut processing. The polishing machine is a spindle that rotates while being located perpendicular to the pressing axis for pressing the lens, which is a material. (Spindle) is installed in the lower part of the pressing shaft, the spindle is designed to be able to tilt around the center. This is mainly used when placing many small workpieces and machining them simultaneously.

With reference to the accompanying drawings, such as a conventional grinding machine 1 to 4 as follows.

As shown, the grinding | polishing machine 2 in this embodiment was shown as having one set of the pressing shaft 30 and the spindle 52 as an example, but the grinding machine which has two sets of the pressing shaft and a spindle also has one set of the pressing shaft. It has the same structure as the grinding | polishing machine 2 which has the 30 and the spindle 52. FIG.

Looking at the configuration of one side shown in the cross section in Figure 1, the grinding machine 2, the pressing shaft 30 on the upper surface of the plate-shaped base frame 10 formed to have a constant height by the support frame 12 The lower part is provided with a spindle 52 corresponding to the pressing shaft 30.

The pressing shaft 30 is lifted up and down by the lifting shaft 40 on the rear of the base frame 10, the lowering the pressing shaft 30 is designed to descend through the base frame 10.

In addition, a control unit configured to control the grinder 2 including various switches and the like is provided on the upper portion of the base frame 10 spaced apart from the lifting shaft 40.

In addition, the lower portion of the base frame 10 corresponding to the pressing shaft 30 is provided with a spindle 52 provided in the same line corresponding to the pressing shaft 30.

The spindle 52 is installed in the housing 50 provided on the lower surface of the base frame 10, and one side of the housing 50 is provided with a driving means 56 for providing rotational power to the spindle 52. do.

The drive means 56 includes a drive motor 56a and a reducer 56b formed by joining a plurality of gears to reduce the rotational force of the drive motor 56a.

On the other hand, the housing 50 is the upper both sides are supported on the lower surface of the base frame 10, one side is receiving power by the drive means 56 consisting of a motor 56a and a reducer 56b predetermined And to tilt in range.

In addition, the upper portion of the housing 50 is provided with a polishing cylinder 60 to accommodate the upper portion of the spindle 52, jig (not shown) to have a lens on the upper surface of the spindle 52 ) Is fastened and installed, and a nozzle 54 for supplying air to the recess 52a and the jig is installed in the polishing cylinder 60 in a state where the length can be adjusted.

A drain port 62 is formed at the front lower portion of the polishing cylinder 60 to discharge the abrasive oil supplied onto the spindle 52 in the polishing cylinder 60 through the nozzle 54. Although not shown in 62, a separate drain pipe is installed and connected to the waste polishing oil reservoir.

On the other hand, the lower portion of the housing 50 is provided with an abrasive oil storage tank 20, the abrasive oil is pumped from the storage tank 20 to the upper portion of the abrasive oil storage tank 20 to the nozzle 54 A feed pump 22 is provided for supplying.

The conventional centrifugal polishing machine 2 thus constructed is installed by fastening a predetermined jig (not shown) on the recess 52a above the spindle 52 in a state where the power is connected, and then polishing the lens on the jig. Put on, to operate the drive motor 56a of the drive means 56.

Then, the rotational force of the drive motor 56a is converted to the low-speed rotational force through the reducer 56b and transmitted to the spindle 52, whereby the spindle 52 is driven to rotate at low speed.

Thereafter, the pressing shaft 30 of the upper portion of the base frame 10 is lowered by the lifting shaft 40 to enter the polishing cylinder 60 of the upper portion of the housing 50, and the lower end of the pressing shaft 30 is jagged. By pressing the lens, the lens is brought into close contact with the jig to perform polishing.

At this time, due to the operation of the drive means 56 composed of the drive motor 56a and the reducer 56b, the housing 50 having the spindle 52 is repeatedly subjected to a tilting operation, so that polishing of the lens is even. Will be done.

In addition, when the lens is polished in the polishing cylinder 60 as described above, abrasive oil for accelerating cooling and lubrication of the polishing unit is pumped from the polishing oil storage tank 20 by the supply pump 22 to remove the nozzle 54. Is provided through.

Then, the abrasive oil provided in this way is collected into the polishing cylinder 60 on the upper portion of the housing 50, and the collected polishing oil is drained through the drain port 62 of the polishing cylinder 60 and a separate drain pipe connected thereto. .

On the other hand, when the operation of the polishing machine 2 operated as described above is stopped, the pressing shaft 30 is raised by the lifting shaft 40, the rotation of the spindle 52 is stopped.

Therefore, the operator separates the polished lens from the jig on the spindle 52, and installs another lens to be polished on the jig of the spindle 52 so that the operation according to the above process is repeated.

However, the conventional centrifugal polishing machine 2 thus formed is provided with abrasive oil in the polishing cylinder 60 in which polishing is performed, and the provided polishing oil is provided through a drain port 62 of the polishing cylinder 60 and a separate drain pipe connected thereto. In this case, since the polishing cylinder 60 is installed above the housing 50, the grinding means 60 includes a driving motor 56a for driving the spindle 52 and a reduction means 56b. When the housing 50 is tilted, the polishing cylinder 60 is also tilted together, so that the drain pipe is difficult to be fixed, so that the installation of the drain pipe is difficult, and there are many problems in the installation. There was a problem in that the binding force of the lowering of the abrasive oil flowing in the tube is leaking.

Accordingly, the present invention has been made to solve the problems described above, by installing a separate abrasive oil receiver in the lower portion of the drain opening, without directly connecting the drain pipe to the drain hole of the polishing cylinder tilted like a housing, It is an object of the present invention to provide an abrasive receiver of a centripetal grinding machine, which has a stable piping structure and a rigid wiring structure and a simple wiring structure.
