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.

摘要： 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.

摘要： 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.摘要翻译： 提供可以提高整个机器的刚性的机床。 支撑平台和工具支撑件一体地形成并且彼此相邻布置，从而允许缩短机床的整个长度并提高刚性。 工件切割时产生的工件和冷却剂的切屑通过前倾斜面，右倾斜面，左倾斜面和排气通道而移动，以从排气口排出。 这肯定可以处理芯片等。

摘要： 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.摘要翻译： 本发明涉及一种机床，该机床禁止切屑和冷却液附着到刀具库，使刀具库良好地工作，保持工具相对于手柄臂和机床主轴单元的良好定位精度等， 并抑制加工精度的恶化。 刀库是机床的刀具更换装置，通过在移动台车上安装夹臂夹持工具支架，使多个移动台车沿轨道循环。 主轴头安装刀架，并利用刀架支撑的刀具加工加工物体。 盖包括覆盖刀库的上板部，覆盖外周侧的上部的外板部，覆盖外周下部的下板部和覆盖内周部侧的内板部 。 盖可以防止由加工产生的切屑等附着到工具架等。

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.摘要翻译： 提供一种机床，其中用于支撑夹具的装置可以足够靠近用于支撑工具的装置。 当电机将旋转台（12）向前侧旋转约90度时，旋转马达（14）位于凹（130）内。 在旋转电动机和凹部之间存在预定的空间。 即使旋转台旋转，旋转马达也不接触工具支架（30）。 即使旋转电机由于旋转台的旋转而接近工具支架，旋转马达也位于凹面中，旋转马达不接触工具支架。 因此，可以缩短工具支撑和支撑平台（10）的整个长度。
