Abstract

(57) [Summary] [Purpose] A chip cover that prevents chips from entering by eliminating the openings on both sides of the tilted telescoping cover provided between the column and saddle of the saddle-moving vertical machining center. [Structure] A tilted telescoping cover 11 having a large height of a side plate is attached between a front end surface of a column 3 and a rear end surface of a saddle 2, and the side plates are adjacent to each other with a slight gap inside the side plate of the tilted telescoping cover. As described above, the Y-axis guiding telescopic cover 13 having a high height is provided so that the chips do not enter the cover.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip cover between a column and a saddle of a saddle moving type machining center.

[0002]

[Prior Art]

 For example, in the vertical machining center shown in FIG. 4, the slanted telescopic cover 103, which is conventionally provided between the column 101 and the saddle 102, has both ends bent upward to form a chip drop prevention bank, and the chips are cut upward. It is a root type for pouring into the gutter 104, and there is no side plate on both sides a and it is left open.

[0003]

[Problems to be Solved by the Invention]

 The tilted telescoping cover with both sides left open as described in the related art has a problem that chips are more likely to enter than the open part and cleaning of the chips once entered is very troublesome. The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to prevent chips from entering by eliminating the openings on both sides of the inclined telescopic cover. Is to provide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the chip cover for a machining center according to the present invention is a saddle-moving type machining center, in which an inclined telescoping cover provided between the column and the saddle and covering the upper part of the bed guides the saddle on the bed. The telescoping cover or the gap prevention plate to be covered is arranged so that it overlaps with both ends on the outside with a slight gap.

[0005]

[Action]

 While cutting, the tilted telescoping cover expands and contracts by changing the tilt angle while following the Y-axis movement of the saddle, and at the same time the telescoping cover for Y-axis guidance also expands and contracts following the Y-axis movement of the saddle, but is always for Y-axis guidance. Since the side surface of the inclined telescopic cover overlaps the side surface of the telescopic cover with a slight gap, chips and / or cutting fluid that fall onto the inclined telescopic cover will not enter the cover.

[0006]

【Example】

 Examples will be described with reference to FIGS. 1 to 3. In the vertical machining center shown in FIG. 1, a guide 1a in the Y-axis direction is provided on a bed 1 provided on the floor, and a saddle 2 is movably mounted on the guide 1a and placed on the saddle 2. The table 8 is mounted on the X-axis guide provided at the position so that it can be moved and positioned. A column 3 is erected on the rear side of the bed 1, and a spindle head 4 is movably mounted on a Z-axis direction guide provided on the front side of the column 3 and is not shown on the spindle head 4. The main shaft is rotatably supported. Further, a magazine device 5 is attached to the left side surface of the column 3, and a tool exchanging arm unit 7 having an exchanging arm 6 capable of rotating and withdrawing / inserting is attached between the magazine device 5 and the spindle head 4.

A gutter 9 for receiving chips is attached to the rear side surface 2 a of the saddle 2, and an inclined telescopic cover 11 is provided between the gutter 9 and the front side surface of the column 3 with a flow gradient. ing. The front cover 11a of the tilted telescopic cover 11 is pivotally supported by the gutter 9 and the rear covers 11b are pivotally supported by the vertical covers 12 fixed to both sides of the column. As shown in, the tilt angle changes at the same time as the saddle 2 expands and contracts following the Y-axis movement. Further, below the inclined telescopic cover 11, there is provided a telescopic cover 13 for covering the Y-axis guide 1a on the bed. The front cover 13a of the telescopic cover 13 is fixed to the rear end face of the gutter 9, and the rear cover 13b is attached to the bed. Is stuck to. The heights of both side plates 13c of the telescopic cover 13 and the side plates 11c of the inclined telescopic cover 11 are set so as to overlap each other with a slight gap.

Next, the operation of this embodiment will be described. The tilted telescopic cover 11 expands and contracts while following the Y-axis movement of the saddle 2 while changing the tilt angle, and the Y-axis guiding telescopic cover 13 also expands and contracts following the Y-axis movement of the saddle. Most of the chips and cutting fluid falling on the inclined cover 11 flow into the gutter 9 by using the inclination angle to the front side in the Y-axis direction, but a part of the chips and cutting fluid falling to the side plate 11c side are side plates. Since 11c and 13c are deeply overlapped with each other and there is only a slight gap, they do not enter the telescopic cover 11. Note that the telescopic cover 13 that covers the Y-axis guide 1a is not always necessary, and vertical gap prevention plates that overlap the side plates 11c of the tilted telescopic cover 11 with a slight gap are provided on both sides of the Y-axis guide 1a. Can be omitted.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. The height of the side plates of the Y-axis guiding telescoping cover and the tilting cover is increased so that they overlap with each other with a slight gap, so that there is no open side surface and there is no gap on the bed between the column and saddle. Since chips do not enter, it is not necessary to clean the chips that are troublesome to remove and maintenance is easy.
