Problems solved by technology

Therefore, since the second cover member cannot effectively use the entire length to perform the covering function, and the length dimension of the second cover member must be enlarged correspondingly due to the size of the overlapping portion, there is a problem that the cost of the second cover member becomes high.

Embodiment Construction

[0041] The telescopic guard plate of the machine tool of this embodiment is provided with a plurality of cover bodies that are assembled so as to be relatively movable, overlap inside and outside, and expand and contract through relative movement. A pair of guide members is provided on the upper portion, and a pair of guided members engaged with the pair of guide members is provided so as to extend cantilever from the base end portion of the outer cover of the inner cover toward the outer cover side.

[0042] (Example)

[0043] The machine tool 1 as a general vertical machining center will be described. Such as figure 1 As shown, the base body 2 has a column 3 erected on its rear side. On the front side of the column 3, the base body 2 is equipped with a Y direction drive mechanism 5 for moving the movable table 22 in the Y direction and an X drive mechanism 5 for moving the movable table 22 in the X direction orthogonal to the Y direction. Directional drive mechanism 6.

Abstract

In the left telescopic cover 25A for the machine tool having a plurality of cover bodies 26A, 27A which are overlapped inside and outside with each other and are combined so as to extend and contract by a relative motion. In order to simplify a supporting structure of a plurality of cover bodies composing the telescopic cover, and further can effectively utilize the whole of the respective cover bodies composing the telescopic cover, a pair of guiding members 31A extending in the X direction (extending and contracting direction) are provided on both side wall portions of the outside cover body 26A, and a pair of guided members 34A protruding in the extending and contracting direction from the base end portion of the outside cover body 26A side toward the outside cover body 26A are provided on both side wall portions of the inside cover body 27A. As a result, a pair of the guided members 34A are engaged with a pair of the guiding members 31A so as to slide respectively.

Description

technical field [0001] The present invention relates to a telescopic guard covering the upper side of a drive mechanism that drives a movable table provided on a machine tool, having a plurality of covers that can be expanded and contracted by relative movement. Background technique [0002] Conventional machine tools independently drive the saddle and the table in the X and Y directions, positioning the workpiece to be cut, and cut the workpiece with the cutting tool mounted on the spindle head supported by the column. processing. In such machine tools, in order to protect the drive mechanism of these saddles and tables from cutting chips, the upper side of the drive mechanism is covered by a telescopic guard. [0003] For example, in the telescopic guard described in Japanese Patent Laid-Open Publication No. 22042 in 2005, in the first embodiment, the upper side of the ball screw and the linear guide rail of the drive mechanism that reciprocates the table in the X directi...
