Definitions
- the present invention relates to a numerically controlled machine tool for processing a large workpiece such as an aircraft component mounted on a workpiece support by moving a spindle on which a tool is mounted in X, Y and Z directions.
- a large workpiece such as an aircraft component mounted on a workpiece support by moving a spindle on which a tool is mounted in X, Y and Z directions.
- the inherent performance required of such machine tools is to provide a table on which large workpieces can be mounted for machining, and to provide sufficient feed shaft stroke for machining large workpieces. That is, it is possible to process all parts and shapes of large and complicated parts all in one setup. In addition, it is necessary to process such parts efficiently, at high speed and with high accuracy. Further, it is preferable that the size of the workpiece to be machined is different for each machine tool user, and that a machine tool of a size required by each user can be manufactured in a timely and prompt manner and installed in a factory.
- the table of the machine tool must be large, but this large table must be connected to the X, Y, and Z axes.
- a configuration that can move in the direction along the orthogonal feed axis of the robot and in the direction along the rotary feed axes A, B, and C is disadvantageous from the viewpoint of high-speed, high-precision machining. It needs to be considered. Therefore, unlike a normal machine tool, a machine tool for machining large parts has a fixed table, and the main spindle, which grips and rotates the tool, is equipped with orthogonal feeders and rotary feeders. It must be movable in the direction of the feed axis and in the direction of each rotary feed axis.
- the X axis and the Y axis are orthogonal to each other in the vertical plane, and extend in the horizontal direction and the vertical direction, respectively, and the Z axis extends in the horizontal direction perpendicular to the X axis and the Y axis. I do. Also, the directions of the A-axis, B-axis, and C-axis indicate the rotation directions around the X-axis, Y-axis, and Z-axis, respectively.
- a symmetric multi-axis linear motor machine tool described in Japanese Patent Application Laid-Open No. HEI 8-31845.
- This machine tool has a vertical gantry that can move in the X-axis direction on vertically opposed frames, a saddle that can move in the Y-axis direction on the vertical gantry, and a Z-axis direction that can move on the saddle.
- a spindle head provided at the front end of the ram for rotatably supporting a spindle on which a tool is mounted, and a table fixed in front of the frame to place a disc, an X-axis,
- Each feed direction in the Y-axis and Z-axis directions is driven by a linear motor.
- the vertical gantry is guided by the upper and lower parts of the frame with respect to the frame and is driven by a linear motor.
- the stator and the mover of the linear motor are the mover of the stator. It is mounted vertically symmetrically so that the suction forces against are canceled each other up and down.
- X-slide, Y-slide supported and guided in the through-hole of the X-slide and movable in the Y-axis direction, and Z-slide supported and guided by the Y-slide and movable in the Z-axis direction
- a spindle head provided at the front end of the Z-slide for rotating and supporting a spindle for mounting a tool, and a table fixed in front of the vertical bed for mounting a work, and an X-axis and a Y-axis.
- the guide In each of the feed directions in the Z-axis direction, the guide is guided by a pair of rail-shaped guides, and is driven by a pair of linear motors.
- the machine tool with a pallet changing device disclosed in this document has a X-axis, Y-axis, and Z-axis direction between a spindle head that rotationally supports a spindle on which a tool is mounted and a table on which a workpiece is placed. It is composed of a machine body that performs relative movement and processes a workpiece, and a pallet exchange device that is provided adjacent to the machine body and that exchanges pallets with a table.
- this pallet exchange device has a plurality of surfaces on which the pallet is mounted, and rotates about a horizontal rotation axis. It is structured to be indexed to the let-out position, the standby position, or the work washing position.
- large machine tools for machining large parts such as machine tools for aircraft parts, generally have a fixed table on which large workpieces are fixed and are immobile.
- the main spindle which grips and rotates the tool, has orthogonal feeders and rotary feeders. It is configured to be able to move in the Z-axis direction and rotate in the A-axis, B-axis, and C-axis directions.
- machine tools typically have a horizontal spindle and relatively long X- and Y-axis strokes so that tall, large columns can be placed on the bed.
- the spindle head moves along the horizontal X-axis direction, and the spindle head moves on the column in the Y-axis direction.
- the work itself becomes large, so that it takes a long time to set up the work on the table, remove chips from the work after machining, or remove the chips. Therefore, the machine tool stops during the setup operation, and the operation rate of the machine decreases.
- the moving body (spindle head and column) moving in the X-axis direction must be large and heavy. For this reason, high-speed feeding becomes difficult, and there also arises a problem that it becomes difficult to maintain high position accuracy in the X-axis direction due to frictional resistance due to the weight of the moving body moving in the X-axis direction.
- a pallet exchange device as described in Japanese Patent Application Publication No. 9-261 may be attached.
- the need to handle large workpieces necessitates a large installation space and a large configuration, causing another problem that the required costs are considerably higher.
- the above-mentioned Japanese Patent Application Laid-Open No. Hei 8-31845 or Japanese Patent Application Laid-Open No. As in the machine tool described in Japanese Patent Publication No. 2727, an X-axis direction guide is provided in two places above and below the base with a frame-shaped base, and a frame-shaped X-axis slide is similarly formed.
- the robot is guided by the upper and lower guides and moved. In this way, guidance in upper and lower two places, When driven, the moving body does not become cantilevered, so it is possible to secure the required rigidity while keeping the moving body relatively lightweight. Also, if a linear motor is used as the moving drive means of the moving body, high-speed feeding can be realized.
- the present invention has been made in view of these problems, and its purpose is to make it possible to process a large workpiece at high speed and with high accuracy, and to easily set up a large workpiece.
- the goal is to obtain a numerically controlled machine tool.
