Description

Manufacturing apparatus and manufacturing method of laboratory optical table {MANUFACTURING APPARATUS AND METHOD OF OPTICAL TABLE FOR LAB}

The present invention relates to an apparatus and method for manufacturing an optical table used in various experiments in laboratories at universities, research institutes, etc., and more specifically, to manufacturing an optical table that can be usefully used in measurement experiments of sensitive equipment or laser experiments. It relates to devices and methods for doing so.

In general, an optical table is a type of platform used in laboratories such as universities and research institutes to conduct various experiments such as optics, lasers, semiconductors, displays, and life sciences.

Typically, industrial sites or laboratories are equipped with tables (platforms) for measuring precision instruments, and various equipment for experiments are placed on these tables.

For example, optical tables are used for measurement experiments on sensitive equipment or laser experiments. These optical tables are installed in a structure where experimental equipment, instruments, optical lenses, and component parts are fastened, and provide excellent static and dynamic rigidity. .

Such an optical table has a thickness of approximately 25 mm to 400 mm and an area of up to 3,500 mm × 1,500 mm, and the top plate of the optical table in this case is made of stainless steel material with a thickness of approximately 4 mm to 6 mm.

In addition, holes and countersinks with a diameter of about 5.3 mm are machined at intervals of about 25 mm on the top plate of the optical table, and when the top plate area is up to 3,500 mm × 1,500 mm, approximately 5,000 holes are machined. do.

When processing holes in the top plate of such an optical table, the holes are currently processed using a laser processing method due to the thin thickness of the top plate and the large area of the top plate.

However, when processing holes using laser processing, there is an economic burden in terms of cost.

For example, the processing cost per hole is about 100 won, and processing 5,000 holes costs about 500,000 won, so when manufacturing one optical table, a significant amount of money is spent on hole processing alone, which is the total cost of manufacturing an optical table. This is a greatly increasing burden.

In addition, after machining a hole on the top of the optical table, countersinking work must be done on the hole machining area, but in the past, workers used a hand drill to do each task manually, which took a lot of time. There are disadvantages to the overall quality of the optical table, such as poor durability and uneven countersink shape as workers do it manually.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

1 to 8 are perspective views, plan views, and cross-sectional views showing a method of manufacturing an optical table for laboratory use according to an embodiment of the present invention.

As shown in Figures 1 to 8, the method of manufacturing the optical table for laboratory use is to form holes/countersinks/tabs on the top plate of an optical table used as a table in a laboratory, etc., especially a top plate that is thin and has a large area. , it is a method to reduce manufacturing costs and secure excellent manufacturability by adopting a drill processing method instead of existing laser processing, and to produce a high-quality table with excellent table flatness by adopting an appropriate support and reinforcement structure.

First, as a first step, a step of preparing a square plate-shaped upper plate 10 on which various equipment is placed during the experiment is performed.

The top plate 10 is made of a stainless steel material, etc., and this top plate 10 can have a thickness of about 2 to 8 mm, preferably 4 to 6 mm, and an area of up to 3,500 mm x 1,500 mm. do.

Next, as a second step, a hole 11, a counter sink 12, and a tab 13, which are used for fastening various equipment on the top plate 10, are formed on the top plate 10. .

The hole 11 formed in the upper plate 10 can be processed by a multi-axis drill machine moving in the X-axis, Y-axis, and Z-axis directions, which will be described later, by one up and down operation of the head equipped with four drills. Four holes 11 can be formed simultaneously.

Here, the holes 11 can be machined to a diameter of about 5.3 mm at intervals of about 25 mm, and each hole 11 processed in this way is arranged in a grid over the entire area of the top plate 10. form can be achieved.

The counter sink 12 is a form in which the upper entry section of each hole 11 is processed into an inclined plane of approximately 45°, that is, the upper entry section of each hole 11 is chamfered at approximately 45°, and the hole After (11) is processed, it can be formed by continuous and sequential processing.

For example, when machining the hole 11 and the countersink 12 on the top plate 10 in the second step, a drill that operates downward (e.g., a drill equipped with a drill bit and a countersink bit in stages) After pre-machining the hole 11 using ), the countersink 12 can be post-machined using a drill that continues to operate downward.

In other words, in the second stage, the hole 11 and the counter sink 12 can be processed simultaneously and automatically in one process. Ultimately, by adopting this processing method, the number of processes can be reduced, and at the same time, the number of steps can be reduced compared to the existing manual work. (12) Uniform processing quality can be secured.

The tab 13 is a thread formed on the inner peripheral surface of each hole 11, and the tab 13 can be processed by a multi-axis drill machine moving in the X-axis, Y-axis, and Z-axis directions.

In other words, the tap 13 is machined on the inner peripheral surface of each hole 11 by one up and down operation of a head equipped with four machining taps (e.g., a head equipped with four machining taps mounted instead of four drills). It becomes possible.

In this way, by performing the processing of the tap 13 through an automated process using a drill machine instead of the existing manual work, it is possible to reduce the surface roughness of the thread, enable efficient screw tightening, and ensure excellent tap processing quality, such as reducing the defect rate when tightening screws. It becomes possible.

Next, as a third step, attaching the seal cap 14 to the bottom of the top plate 10 is performed.

The seal cap 14 is in the form of a cylindrical cap with a wide diameter at the open area and a narrow diameter at the closed area, and is installed in a structure in which one is attached to each hole 11 formed in the upper plate 10 with an instant adhesive or the like. do.

The seal cap 14 installed in this way can form a grid-like arrangement structure aligned with five rows.

This seal cap 14 serves to prevent the adhesive 16 applied in the fifth step from seeping into the threads of the tab 13.

Next, as a fourth step, the step of installing the wall 15 on the bottom of the top plate 10 is performed.

This wall 15 is installed in a structure that stands along the edges of the four sides of the top plate 10, and can be fixed by tag welding or the like.

Next, as a fifth step, applying the adhesive 16 to the bottom of the top plate 10 is performed.

This adhesive 16 is applied from the inner area of the wall 15 installed at the edge of the top plate 10 over the entire area of the top plate, and the adhesive 16 applied in this way is applied to the core 18 installed in the sixth step. It plays a role in fixing the.

Here, the adhesive 16 is preferably applied to a thickness of about 0.5 to 1 cm in order to stably hold the core 18.

Next, as a sixth step, a core 19 is included as a means of maintaining the flatness of the table top while maintaining the gap between the upper plate 10 and the lower plate 17.

The core 19 is a plate made of a wave-shaped band, and is in close contact with the bottom surface of the upper plate 10 and the upper surface of the lower plate 17 through the upper and lower portions, and is erected vertically in the longitudinal direction of the table, that is, the upper and lower plates 10. ,17) is installed in a structure arranged side by side along the longitudinal direction.

A plurality of such cores 19 are provided, and each core 19 can be arranged side by side along the longitudinal direction of the upper and lower plates 10 and 17, while simultaneously extending in the width direction of the upper and lower plates 10 and 17. Along the way, they can be arranged side by side while maintaining a certain distance, for example, a gap corresponding to the gap between each row of the seal caps 14.

In addition, the core 19 can be supported at both ends by the core bracket 21 while being fixed by the adhesive 16 applied to the bottom of the top plate 10.

For this purpose, the core bracket 21 is in the form of a bent bar with a “ㄷ”-shaped cross-section, and the core mounting groove 14 consisting of a straight entrance part and a circular inner part is provided on the lower horizontal member of the “ㄷ”-shaped cross-section. is formed, and the end of the core 18 can be supported in a structure where the end of the core 18 is inserted into the entrance and inner part of the core mounting groove 14.

This core bracket 21 is installed in a horizontal position and fixed to each inner surface of both walls 15 by welding or the like using the side surfaces, so that it can hold both ends of the core 18.

In addition, the cores 18 form a pair of two cores 18 that face each other and form two rows in a vertical position at the same time, and the combination of the two cores 18 forming a pair in this way forms the seal cap 14. As they are accommodated inside, they form one row.

That is, one seal cap 14 is inserted into each circular recess 19 formed by combining the two cores 18 forming a pair, and as can be seen in FIG. 6, the seal cap 14 is cylindrical. The two outer peripheral surfaces are in close contact with the inner peripheral surface of the circular recess 19, and thus the seal cap 14 can be supported by the core 18 while inserted into the recess 19.

Accordingly, the core 19 is fixed by inserting both ends into the core bracket 21 on the wall 15 and is fixed by the adhesive 16 to maintain a solid installation state. In this state, the upper and lower ends are connected to each other. As it comes into close contact with the upper plate 10 and lower plate 17 sides, the upper plate 10 and lower plate 17 are supported by the core 19 and are able to maintain a gap from each other, which ultimately prevents the load from equipment, etc. from being applied. Even in case of loss, both the edge area supported by the wall 15 as well as the central area supported by the core 19 can maintain an accurate flatness without sagging or deformation.

Next, as the seventh step, the step of installing the lower plate 17 that closes the inner space of the table containing the core 18, seal cap 14, etc. is performed.

The lower plate 17 is in the form of a square plate with an area corresponding to the upper plate 10, and is installed at the lower end of the wall 15 by tech welding, etc. to connect the upper plate 10, the lower plate 17, and the wall 15. It is possible to finish the inner space of the table surrounded by

In this way, when all of the first to seventh steps are completed, the upper plate 10 and the lower plate 17, the wall 15 surrounding the edge, and the core 18 supporting the upper and lower plates 10 and 17 from the inside. ) and a seal cap 14 that protects the threaded portion of the tab 13 is completed.
