Description

TECHNICAL FIELD [0001] The present invention relates to a perforated panel,

The present invention relates to a perforated panel chamfering apparatus for a clean room floor. More particularly, the present invention relates to a perforated panel chamfering apparatus for clean room floor, The present invention relates to a perforated panel chamfering apparatus for a clean room floor improved to be chamfered while being rotated by 90 degrees with a cutter.

Generally, the floor of the clean room where various special equipment is installed for production and research such as semiconductors, high-junction circuit manufacturing room, gene engineering laboratory, etc., is provided with a floor panel on a plurality of beams provided at the upper end of the column, The panel is formed with a plurality of through holes to effectively absorb and remove fine dust, dust, and particulates from the outside, and to distribute the loads of various special equipments uniformly to prevent cracks or sinking due to loads concentrated on one floor.

1, an upper plate 110 having a predetermined thickness t and an outer wall 120 on four sides of the upper panel 110, and an upper plate 110 A bottom plate 100 on which a plurality of load distribution main ribs 130 and auxiliary ribs 140 for reinforcing the strength of the top plate 110 are provided at regular intervals in a grid pattern; A tile 200 of a synthetic resin material adhered to the surface of the top plate 110 of the bottom plate 100 with an adhesive; . The resin tile 120 is adhesively attached to the base panel 110 with a thin plate formed of a thermosetting synthetic resin material to complement the electrical characteristics of the base panel 110.

Since the bottom panel is cast by die casting, it is necessary to obtain a dimensional accuracy of four sides, and to prevent the synthetic resin tile adhering to the upper surface of the floor panel from being slightly wider than the top panel Since the burrs are generated at the edges of the four sides by pressing the tiles and integrating them on the surface, it is possible to obtain dimensional accuracy for the four sides of the floor panel and to reduce the burrs on the four sides of the floor panel Chamfering must be performed. Such chamfering is necessary for correct installation work in the installation of the floor panels and to prevent the occurrence of problems which cause edge corners of adjacent panels due to burrs at the edge of the panel.

The burr removal by the synthetic resin tile adhering to the upper surface of the floor panel is generally performed by chamfering with a milling machine. As an example of such a milling machine for chamfering, a milling cutter module of an edge milling machine disclosed in Korean Patent No. 10-1420816 (registered on Jul. 11, 2014) has guiding members for linear movement on the lower side A mounting table formed; A moving unit provided on an upper surface of the mounting table and including a plurality of screw jacks vertically movable; A clamping unit provided on an upper surface of the loading table adjacent to the moving units, the clamping unit including a plurality of fixing blocks capable of protruding and retracting on an outer surface thereof; The clamping unit can be moved up and down by being connected to the screw jack of the moving unit on the lower surface, and a guiding groove recessed to partially fit the clamping unit is formed on the lower surface, and the fixing block is brought into close contact with the guiding groove A moving frame which can be fixed without shaking; A motor for a milling cutter mounted on the moving frame; And a milling cutter provided on one upper surface of the moving frame and rotated by a rotational force from the milling cutter motor.

However, there is a problem that the surface of the tile attached to the upper surface may be damaged by the clamp when chamfering the floor panel by the milling cutter module of the conventional edge milling machine.

As another conventional example, the Korean Registered Patent No. 10-1484626 (registered on Apr. 13, 2014) includes a control shaft disposed across the center of the bed, a driving motor for controlling the rotation of the control shaft, A traveling body adjusting section for moving the polishing cut section to a desired working position by a neutral adjustment nut, a traveling body which is guided by the LM guide device by the rotation operation of the adjusting shaft fastened to the adjusting nut of the traveling body adjusting section to forward and backward, And a side fixing device for fixing the processed sheet material so as to be able to be processed by the above-mentioned milling cutter device. The polishing apparatus includes a polishing unit And a rotating device for rotating the lower plate at a central portion of the space formed by arranging and disposing the processed plate material and arranging the processed plate material at the target angle A plate adjusting device, an angle adjusting part constituted by an upper plate adjusting device for holding a processed plate material by rotating and clamping the processed plate material placed on the lower plate to rotate the rotating device, and an angle adjusting part There is disclosed a side continuous working apparatus in a non-ferrous metal plate including a center adjuster for aligning the center of a processed plate.

However, in the conventional side surface processing apparatus, even if the processed plate is held by the upper plate, the position of the plate can be displaced by the cutting pressure at the time of side processing, which makes it difficult to precisely dimension the clean floor panel. Further, the structure of the angle adjusting unit for indexing and rotating the processed plate is complicated, resulting in an increase in the manufacturing cost of the apparatus, and there is a problem of positional displacement of the plate member when adjusting the angle by the angle adjusting unit.
