In a machine tool, a table, a tool rest, a main shaft, a tailstock, a vibration isolator, etc. are provided with a conveying unit conveying along a conveying axis in order to perform various machining.

Such a machine tool can be divided into a horizontal type machine tool and a vertical type machine tool according to the arrangement direction of the main shaft. In the horizontal type machine tool, the central axis of rotation of the main shaft is arranged at right angles to the direction of gravity, and in the vertical machine tool, the central axis of rotation of the main shaft is arranged to coincide with the direction of gravity.

In general, a machine tool supplies cutting oil when processing a workpiece using a tool to prevent thermal deformation of the workpiece and the tool due to frictional heat. During machining, chips are generated in the workpiece.

Therefore, in general, in a machine tool, various cover devices are installed in order to protect various peripheral devices and workers installed in the non-processing area from cutting oil and chips scattered during machining in the machining area.

As shown in FIG. 1, the cover device of the conventional vertical machine tool, particularly the large vertical lathe 1 among the vertical machine tools, facilitates horizontal movement for smooth movement of the ram head 2 and vertical movement for setting the workpiece. In order to avoid axial interference, the cover (3) and door (5) of the structure with an open part (5) at the top, which cover up to half the position of the machine tool, rather than covering the entire machine tool, During machining in the machining area, cutting oil or chips scatter through the upper opening 5 to contaminate the surrounding environment of the machine tool. And, there was a problem that the worker was exposed to risks and the productivity decreased.

In order to solve this problem, as shown in FIG. 2 , the cover device of the conventional vertical machine tool, in particular, the large vertical lathe 1 among the vertical machine tools includes the cover 3 and the door having a structure that covers the entire machine tool. (5), it is possible to prevent the scattering of cutting oil or chips by removing the opening shown in FIG.

However, as shown in Fig. 2, in the case of the large vertical shelf 1, the height is about 6 meters, which limits installation space and transportation, and causes inconvenience to workers during assembly and maintenance due to the enlargement of the equipment. In addition, as the manufacturing cost of the cover device of the vertical machine tool increases by 3 to 5 times or more than the conventional one, the overall production cost of the machine tool rises eventually, marketability and exports decrease, space utilization is extremely reduced, and the user There was a problem that the machine tool could not be observed at once, causing a safety problem.

As shown in FIGS. 7 to 8 , the processed workpiece 14 seated on the chuck 120 of the processing unit 110 of the processing unit 100 is removed during non-processing or the chuck 120 of the processing unit 110 is removed. ), the central part 121 of the chuck must be opened to seat the unprocessed workpiece 14 in the chuck. That is, if the central portion 121 of the chuck is not opened as shown in FIGS. 7 to 8 , the workpiece cannot be set through a crane during non-processing, thereby reducing productivity and causing safety accidents.

9 and 10, in the cover device 10 of the vertical machine tool according to the present invention, the sliding door part 330 is opened by the driving force of the power transmission part 350 during non-processing) and, accordingly, the central portion 121 of the chuck 120 of the processing unit 110 is opened.

Thereafter, as shown in FIG. 10 , the central part 121 of the chuck is opened by the opening of the sliding door part 330 of the sliding door unit 300 during non-processing, and the processing placed on the chuck 120 by the crane 13 . It is possible to remove the processed workpiece 14 or to easily mount the unprocessed workpiece 14 on the chuck 120, thereby maximizing user convenience and preventing personnel accidents in advance, and setting work for heavy workpieces. By proceeding quickly, productivity can be maximized by reducing non-working time. That is, the sliding door unit 300 of the sliding door unit 330 is opened by the driving force of the power transmission unit 350 only when the work is set during non-processing.

As shown in FIG. 13 , the first support part 341 of the shielding part 340 of the sliding door unit 300 includes a sliding fixing part 320 fixedly installed on the base frame 311 of the frame part 310 and such When the sliding door part 330 supported by the sliding fixing part 320 in a cantilever shape and sliding open and closed by the driving force of the power transmission part 350 is closed, the load in the gravity direction of the sliding door part 330 is applied. support That is, the first support part 3410 performs an operation while making a line contact with the duct part 370 by the first bearing part 380 installed on a part of the first support part 341 , thereby forming the sliding door part 330 . First and foremost, the load is firmly supported.

The second support part 342 is an upper surface of the guide part 510 extending in the horizontal direction to a part of the oil supply unit 500 by the second bearing part 390 installed to a part of the second support part 342 . The operation is performed while making line contact with the second to firmly support the load of the sliding door unit 330 . The plate part 432 of the cover unit 400 is installed under the oil supply unit 500 .

As such, although the first support part 341 and the second support part 342 are formed in a cantilever shape by supporting the load of the sliding door part 330 double, durability may be improved and a compact structure may be formed.

Although not necessarily limited thereto, the first, second, and third bearing parts 380 , 390 , and 391 may be formed as cam followers.

In addition, as shown in FIG. 15 , the second cover part 420 has a sliding door part 330 to open the central part 121 of the chuck in order to remove the processed workpiece during non-processing or to seat the unprocessed workpiece on the chuck. ) is opened, the ram head unit 200 moves in the left horizontal direction, which is the origin of the machine tool, and stops while the second cover part 420 is fixed, at this time the sliding door part 330. It operates in the form of being transferred as it opens.

In addition, the second cover part 420 has a shape in which the sliding door part 330 is fixed in a closed state (open) during processing, and the ram head unit 200 is horizontal for processing. It has a variable structure that operates in the form of being transported while transporting.

Therefore, the cover device of the vertical machine tool according to the present invention opens the center of the chuck when the sliding door unit mounts or removes the workpiece on the chuck of the machining section during non-processing, and during machining, the ram head unit moves in the vertical direction. It completely seals the upper part of the machining part, and the cover unit completely seals the upper part of the machining part during horizontal movement of the ram head unit during machining, avoiding shaft interference and completely preventing the scattering of cutting oil and chips to the upper part of the machining part. It is possible to reduce the manufacturing cost to less than 1/5 while blocking, and to maximize the convenience of transport, assembly and maintenance.

In the detailed description of the present invention described above, although it has been described with reference to preferred embodiments of the present invention, those skilled in the art or those having ordinary skill in the art will It will be understood that various modifications and variations of the present invention can be made without departing from the spirit and scope of the present invention. Accordingly, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
