Laboratory optical table manufacturing apparatus and manufacturing method {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 such as universities and research institutes, and more particularly, to manufacturing an optical table that can be usefully used for measurement experiments of sensitive equipment or laser experiments It's about the device and how to do it.

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

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

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

Such an optical table has a thickness of about 25 mm to 400 mm and an area of up to about 3,500 mm × 1,500 mm, and the upper plate of the optical table at this time is made of a stainless steel material having a thickness of about 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 area of the top plate is about 3,500 mm × 1,500 mm at most, about 5,000 holes are machined. do.

When drilling a hole in the top plate of such an optical table, the hole is currently being processed using a laser processing method because the thickness of the top plate is thin and the area of the top plate is large.

However, in case of processing a hole by a laser processing method, there is an economic burden in terms of cost.

For example, the processing cost per hole is about 100 won, and it takes about 500,000 won to process 5,000 holes. Therefore, when manufacturing one optical table, the entire cost required for manufacturing an optical table, such as a considerable cost for hole processing alone, There is this greatly increasing burden.

In addition, after machining a hole in the upper plate of the optical table, countersinking work must be done on the hole machining part. There are disadvantages in that the overall quality of the optical table is degraded, such as poor performance, countersink shape being inconsistent due to manual work by workers.

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

The counter sink 12 is in the form of processing the upper entry section of each hole 11 into an inclined surface of about 45 °, that is, in the form of chamfering the upper entry section of each hole 11 at about 45 °, After (11) is processed, it can be formed in a manner in which it is continuously and sequentially processed.

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 (eg, a drill equipped with a drill bit and a countersink bit in stages) After the hole 11 is pre-processed using ), the counter sink 12 can be post-processed using a drill that continues to descend.

That is, in the second step, the hole 11 and the countersink 12 can be processed simultaneously and automatically by linking them in one process. Eventually, by adopting this processing method, the number of man-hours can be reduced and at the same time, the countersink compared to the existing manual work can be processed. It is possible to secure the uniform processing quality of (12).

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

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 lower surface of the upper plate 10 .

To this end, the core bracket 21 is in the form of a bent bar having a "c"-shaped cross section, and a core mounting groove 14 formed of a linear inlet portion and a circular inner portion in the horizontal member below the "c"-shaped cross section is formed, and at this time, the end of the core 18 can be supported by fitting into the entrance and the inner part of the core mounting groove 14.

The core bracket 21 is installed in a structure fixed by welding to each inner surface of both walls 15 using the side surface while taking a horizontal posture, so that both ends of the core 18 can be held.

In addition, the cores 18 form a pair of two cores 18 that form two rows side by side while facing each other while taking a vertical posture, and the combination of the two cores 18 forming a pair in this way forms a seal cap 14 By accepting them inward, they form a row.

That is, one seal cap 14 can be inserted and disposed into each circular concave portion 19 formed by combining two cores 18 forming a pair.

Accordingly, both ends of the core 19 are inserted and bound to the core bracket 21 on the wall 15, and at the same time fixed by the adhesive 16, it is possible to maintain a solid installation state, and in this state, the upper and lower ends are Through this, the upper plate 10 and the lower plate 17 are in close contact with each other, so that the upper plate 10 and the lower plate 17 can maintain a distance from each other while being supported by the core 19. Even when it is lost, both the edge area supported by the wall 15 and the central area supported by the core 19 can maintain an accurate plan view without deflection or deformation.

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

The lower plate 17 is in the form of a square plate having an area corresponding to that of the upper plate 10, and is installed at the lower end of the wall 15 by tech welding, so that the upper plate 10, the lower plate 17, and the wall 15 It is possible to close 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 edges, and the core 18 supporting the upper and lower plates 10 and 17 from the inside ) and the seal cap 14 protecting the threaded portion of the tab 13 is completed.
