Embodiment Construction

[0046] A machine tool according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a table traverse type grinder is taken as an example. Such as figure 1 As shown, the machine tool 10 has: a bed 11; a slender workbench unit 12 that can move along the Z-axis direction on the upper surface of the bed 11; A headstock 13 and a tailstock 14 supporting both ends of the object W; a grinding wheel head 15 movable in the X-axis direction on the bed 11; and a grinding wheel 16 rotatably supported on the grinding wheel head 15 .

[0047] The table unit 12 includes: a traverse table 20 (corresponding to the "base" of the present invention), which can move in the Z-axis direction on the upper surface of the bed 11; and a corner table 30, which is provided in a rotatable manner. on the upper surface of the traversing table 20 ; and an actuator 40 , which adjusts the rotation angle θ of the corner table 30 relative to the travers...

Abstract

The present invention provides a machine tool capable of preventing debris and the like from adhering to the sliding surface of the upper surface of a base and the sliding surface of the lower surface of a corner table. The machine tool (10) is equipped with: a base (20), which is formed into an elongated shape with corners on four sides; a corner table (30), which rotates while sliding on the upper surface of the base (20); The covers (61-64) are rotatably supported by the base (20) or the corner table (30). In the first state where the corner table (30) does not exist on the upper surface of the corner of the base (20), the above-mentioned rotating cover covers the base ( The corner upper surface of 20), in the second state where the corner table (30) exists on the corner upper surface of the base (20), the above-mentioned rotary cover is accommodated under the corner table (30).

Description

technical field [0001] The present invention relates to a machine tool provided with a corner table. Background technique [0002] The machine tools described in Japanese Patent Laying-Open No. 11-77493 and Japanese Patent Laid-Open No. 7-195266 are provided with a cornering operation that slides and rotates on the upper surface of the base in order to perform taper processing or taper correction for forming a tapered portion on a workpiece. tower. The rotation angle of the corner table relative to the base can be adjusted by moving the position of the first end of the corner table relative to the base using an actuator provided at the first end in the longitudinal direction of the corner table. [0003] Here, when the corner table is rotated, the upper surface of the base is exposed. If debris or the like adheres to the sliding surface of the upper surface of the base or the sliding surface of the lower surface of the corner table, it will adversely affect the rotation of...
