摘要:
The present invention relates to a tool changing device that exchanges tools between a main shaft of working machine and a tool magazine, and to a working machine. The tool changing device includes an annular tool magazine provided with a plurality of grip arms supporting a tool holder. The tool magazine is supported by a column supporting a main shaft head provided with a main shaft movably up and down direction so as to enclose an outer circumference thereof. Since the barycentric position of the column in a state where the tool magazine is attached can be made closer to the barycentric position of the column in a state where the tool magazine is not attached, the tool changing device suppresses imbalance in the weight of the column and prevents deterioration in the accuracy of positioning control for the movement of the column.

The present invention provides a machine tool which reliably prevents the rotation and the movement of a turning tool to be attached to a rotatable main shaft via a tool holder with a simple configuration, and which permits a turning process with high process precision, and provides such a tool holder. In a machine tool (1) that attaches tools (3) for rotation process and turning process via a tool holder (30) to an end part of a main shaft (20) which is supported by a main-shaft head (2) and rotates about its central axis, a rotation locking flange (31) is provided on an outer circumference of the tool holder (30) holding the tool (3) to widen outward in a radial direction. Two engaging holes aligned on a circumference of a circle coaxial with the tool holder (30) are formed in the rotation locking flange (31), and the engaging holes are engaged with two engaging projections (23) projecting from a lower face of the main-shaft head (2), and thereby the rotation and the movement in a radial direction of the tool holder (30) are prevented.

A machine tool that can improve rigidity of the entire machine is provided. A support platform and a tool support are integrally formed and arranged adjacent to each other, allowing the entire length of the machine tool to be shortened and the rigidity to be enhanced. Chips of a workpiece and coolant occurred at cutting of a workpiece move through a front inclined plane, a right inclined plane, a left inclined plane and an exhaust passage to be discharged from an exhaust port. This can surely dispose of the chips and the like.

The present invention relates to a machine tool that inhibits the attachment of chips and coolant to a tool magazine, makes the tool magazine work well, keeps good positional accuracy or the like for a tool with respect to a grip arm and a machine spindle unit, and inhibits the deterioration of machining accuracy. The tool magazine is a tool exchange apparatus of the machine tool and circulates plural moving carriages along a rail, as grip arms gripping tool holders are attached to the moving carriages. A spindle head mounts the tool holder, and utilizes tools supported by the tool holder to machine a machined object. A cover includes an upper plate portion covering over the tool magazine, an outer plate portion covering an upper portion at an outer perimeter side, a lower plate portion covering a lower portion at the outer perimeter, and an inner plate portion covering an inner perimeter side. The cover can prevent the chips and the like generated by the machining from attaching to the tool holder and the like.

摘要:
A machine tool is provided in which a device for supporting a jig can sufficiently be close to a device for supporting a tool. When a motor rotates a rotary table (12) to the front side by approximately 90 degrees, the rotary motor (14) is positioned inside a concave (130). A predetermined space is present between the rotary motor and the concave. Even if the rotary table rotates, the rotary motor does not touch the tool support (30). Even if the rotary motor approaches the tool support due to rotation of the rotary table, the rotary motor is positioned in the concave and the rotary motor does not touch the tool support. Thus, the entire length of the tool support and support platforms (10) can be shortened.
