Abstract

(57) [Summary] [Purpose] To provide a sliding surface protection cover that is not complicated and has a structure like a telescopic cover, but is simple and that is attached to a saddle that does not increase the overall size of the cover. [Structure] A partition-shaped moving cover 13 is attached almost vertically to the right side of a saddle 2 which moves in the Z-axis in the entire cover 8 of a lathe, and wipers 14 and 15 are brought into contact with the inner surface of the entire cover on the outer peripheral portion of the moving cover. The accordion cover 16 is provided on the saddle to prevent the cutting fluid splashing from below from entering between the movable cover and the side plate 8a of the entire cover.
In conjunction with the axial movement, the movable cover moves while wiping the cutting fluid and fine chips attached to the inner surface of the entire cover with a wiper.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide surface protection cover fixed to a saddle of a machine tool.

[0002]

[Prior art]

 Conventionally, for example, as shown in FIGS. 3 and 4, the protective cover on the side opposite to the main shaft of the bed sliding surface of the lathe is fixed to the right side surface of the saddle 101 so as to project the L-shaped moving cover 102 so that the entire cover is provided. A fixed cover 104, which overlaps the movable cover 102, is fixed to the inside of the right side surface of the movable member 103 so as to protrude. Structures that prevent penetration by penetration are often used.

[0003]

[Problems to be solved by the device]

 In the case of the bed sliding surface protection cover described in the prior art, since the moving cover 102 projects to the right of the saddle 101, it is necessary to make the entire cover 103 as large as that, which increases the lateral width of the machine and increases the floor space. There is a problem of doing. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a protective cover for a sliding surface that has a simple structure and does not increase the lateral width of the machine. It is a thing.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a machine tool cover according to the present invention is a cover for protecting a guide surface fixed to a saddle in a machine tool overall cover, wherein the saddle has a cross section perpendicular to the saddle moving direction of the whole cover. A partition-like moving cover similar to the shape is provided almost vertically, and a wiper that comes into contact with the inner surface of the entire cover is provided on the outer peripheral portion of the moving cover. It works in conjunction with the saddle while squeezing liquid etc. with a wiper.

[0005]

[Action]

 In conjunction with the Z-axis movement of the saddle, the movable cover moves while wiping the cutting fluid and fine chips adhering to the entire cover with an elastic wiper.

[0006]

【Example】

 Embodiments will be described below with reference to the drawings. In the NC lathes shown in FIGS. 1 and 2, the saddle 2 is movably mounted on the guide 1a provided in the Z-axis direction on the bed 1, and the guide 2a provided in the X-axis direction is provided on the saddle 2. The tool rest 3 is mounted on the base so that it can be moved and positioned. The turret 3 is provided with a turret 4 capable of swiveling and indexing in a plane perpendicular to the Z axis, and a plurality of unillustrated tools are detachably attached to the outer periphery of the turret 4. A headstock 5 is installed on the left side of the bed 1, and a chuck 7 is concentrically fixed to the tip of a spindle 6 rotatably supported by the headstock 5.

The machine is covered with an overall cover 8, and an open / close door 10 for attaching / detaching and changing the work is provided on the overall cover 8. An L-shaped moving cover 9 is attached to the left side of the saddle 2 so as to project to the left side in the Z-axis direction. The left end of this moving cover 9 projects to the left side of the headstock front cover 11 and to the front cover 11. The movable cover 9 is provided with a wiper 12 which is an elastic body that squeezes cutting water, chips and the like. On the right side surface of the saddle 2, a partition-like movable cover 13 having a cross section perpendicular to the Z axis of the entire cover 8 and a similar shape is fixed substantially vertically, and an elastic body such as rubber is attached to the upper surface and the front surface of the movable cover 13. The wipers 14 and 15 are attached. Further, an accordion cover 16 is attached between the lower side of the movable cover 13 and the side plate 8a of the entire cover 8 to prevent the cutting fluid scattered from entering from below. When the movable cover 13 is stopped, the wipers 14 and 15 are in contact with the inner surface of the entire cover 8 without a gap, and when the movable cover 13 is moved, the cutting fluid and fine chips adhering to the inner surface of the entire cover 8 are wiped by the wipers 14 and 15. In addition, it is designed to always prevent the ingress of cutting fluid and chips.

Next, the operation of this embodiment will be described. During the cutting process, the movable cover 13 interlocks with the Z-axis movement of the saddle 2, and the wipers 14, 15 squeeze the cutting fluid and fine chips adhering to the inside of the entire cover 8 to prevent the intrusion. Then, when the cutting process is completed and the tool rest 3 is retracted to the movement end on the side opposite to the main spindle, the movable cover 13 moves to a position where a slight gap is left between the movable cover 13 and the side plate 8a of the entire cover 8. Also, since the front lower side of the moving cover 13 and the side plate 8a are covered by the accordion cover 16, even if a large amount of cutting fluid is used, the cutting fluid that splashes due to splashing or the like may enter the cover. There is no.

[0009]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. A saddle-shaped moving cover similar to the cross-sectional shape of the entire cover is installed almost vertically, and a wiper is installed on the outer periphery of the moving cover to prevent cutting fluid and fine chips from adhering to the entire cover. Since this is done, the space required for the saddle mounting cover in the Z-axis direction can be greatly reduced with a simple structure, which is effective for making the machine compact.
