As shown in the drawings, the present invention is an apparatus for opening and closing an upper part of a processing room installed in a machine tool, and its configuration is roughly divided into a cover part 100, a locking part 200 and a guide part 300.

A main body 110 fixed to the saddle 40 at the rear of the processing chamber 30 and a lid 120 wound around the main body 110 and wound and unwound to open and close the upper portion of the processing chamber 30 The cover portion 100 is formed.

A connection bar 130 is formed at a front end of the lid 120 to connect the locking part 200 and one end of the guide part 300.

A locking part 200 is formed on both side walls 31 of the processing room 30 so as to be symmetrical with respect to each other and to lock the front end of the lid 120 in front of the upper part of the processing room 30 .

The locking unit 200 includes brackets 210 fixed symmetrically to each other in front of both side walls of the processing chamber 30 and a bracket 210 fixed to the brackets 210 and extending parallel to both sides of the lid 120. [ A block 230 which is inserted into a lower portion of the rail 220 so as to slide on the rail 220 and is fixed to a connecting bar 130 formed at a front end of the lid 30 and moves together with the lid 120; And an actuator 240 fixed to the upper portion of the bracket 210. Concave fixing grooves 230a are formed on the block 230 and the fixing grooves 230a are formed on the lower portion of the actuator 240. [ The fixing pin 240a is inserted into the fixing pin 240a.

The cover 120 is connected to one side of the saddle 40 and the other end of the saddle 40 is connected to both sides of the saddle 40 to extend and retract, Is formed.

The guide unit 300 includes a first slider 310 fixed on both sides of the front end of the lid 1200 to support lower portions of both sides of the lid 120 and a second slider 310 fixed to both sides of the saddle 40, And a second slider 320 for receiving the first slider 310 therein.

A first roller R1 is rotatably fixed to the upper portion of the side wall 31 of the processing chamber 30 and one side of the first slider 310 to support the first slider 310 in a slidable manner, And the second roller R2 are respectively formed.

A packing P is fixed to the upper portion of the first slider 310 to seal the gap between the first slider 310 and the lid 120. An upper portion of the side wall 31 of the processing chamber 30 A first brush B1 fixed to the gap between the side wall 31 and the first slider 3100 and a second brush B1 fixed to the inside of the second slider 320 to define the side wall 31 and the second slider 320, And a second brush B2 for closing the gap between the brushes.

The operation state of the present invention configured as above will be described with reference to the drawings.

First, when the cover unit 100 is moved in the forward and backward direction while the lid 1200 is locked by the locking unit 200 and the upper part of the processing room 30 is covered, The fixed body 110 is moved in the moving direction of the saddle 400 and the cover 120 wound inside the body 1100 is wound or unwound by the movement of the main body 110, Lt; / RTI >

That is, when the saddle 40 is moved forward, the sheath 120 with the front end locked in the upper part of the processing room 30 is wound on the main body 110 moving forward with the saddle 40, And moves backward together with the saddle 40 to unlock the main body 110 to close the upper portion of the processing room 300

Accordingly, the cover part 100 can prevent the chips and the like, which are generated in the course of processing the workpiece, from being transferred to the upper part of the processing room 30 by closing the upper part of the processing room 30 while the lid 1200 is wound and unwound by the main body It is possible to block outward splashing.

When the fixing pin 240a of the actuator 240 is inserted into the fixing groove 230a of the block 230, the front end of the lid 120 is locked in the upper front of the processing chamber 30 When the fixing pin 204a of the actuator 140 is inserted into the fixing groove 203a of the block 230, the lock is released to the front end of the cover 120. [ At this time, the rail 220 serves to guide the block 230 to move in a direction in which the lid 120 is wound and unwound.

The guide part 300 guides the cover 120 to the main body 110 while supporting the cover 120 when the cover 120 is wound and unwound. That is, the first slider 310 is inserted into the second slider 320 as the lid 120 is wound by the movement of the main body 110, and when the lid 120 is loosened, 1 slider 310 is released from the inside of the second slider 320 so that the cover 120 is not guided by the guide portion 300 and the guide portion 300 and the cover portion 100 ) Are not brought into contact with each other as in the prior art, so that noise due to friction is not generated

The first roller R1 and the second roller R2 are rotatably fixed on the side wall 31 of the processing chamber 30 and one side of the first slider 310 so that the first slider 310 And the second slider 320 are guided by the first roller R1 and the second roller R2 so that the cover 120 is slid in the direction of winding and unwinding without friction.

The packing P fixed to the upper portion of the first slider 310 hermetically seals between the first slider 310 and the lid 120 and presses the first brush 30 fixed to the upper portion of the side wall 31 of the processing chamber 30. [ The second brush B2 fixed to the inside of the first slider 320 and the gap between the side wall 31 and the first slider 310 and the gap between the side wall 31 and the second slider 320, The gap between the lid 120 and the side wall 31 is sealed.

Accordingly, the present invention can smoothly open and close the upper portion of the processing chamber 30 through the cover portion 100, the locking portion 200, and the guide portion 300 without noise, thereby improving the durability and airtightness .

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.
