Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work machine for performing a work on a work by positioning the work and the work relatively to each other. 2. Description of the Related Art Generally, various types of machine tools (working machines) are used to perform a work such as a boring process on a work to be worked. For example, as shown in FIG. 8, a conventional machine tool 1 includes a main shaft 2 that can move back and forth in the direction of arrow A (vertical direction), and a drill 4 as a tool is mounted on the main shaft 2, for example. ing. On the other hand, the work W is positioned and mounted on the base 5, and a plurality of processing parts 6 a to 6 n are set on the work W. In the conventional machine tool 1 configured as described above, the main shaft 2 moves downward while rotating integrally with the drill 4, so that the main shaft 2 moves to one processing portion 6 a of the work W on the base 5. Drilling is performed. Next, after the spindle 2 is lifted to separate the drill 4 from the workpiece W, the spindle 2
Moves a predetermined amount in the direction of arrow B or the direction of arrow C,
The main shaft 2 is lowered to perform a drilling operation on the other processing portions 6b to 6n. [0004] By the way, in the machine tool 1 described above, for example, when performing various processing on each surface of the work W, the work W is temporarily removed from the base 5 and then removed. It is necessary to mount the work W on the base 5 again so that the surface to be machined faces the drill 4. Further, even if an attempt is made to perform an arc-shaped machining or a spiral machining on the work W, it cannot be easily coped with. As a result, a problem has been pointed out that arbitrary processing such as inclined holes cannot be efficiently performed on each surface of the work W. In addition, since the machine tool 1 is heavy, considerable inertia is generated with the movement of the center of gravity. Therefore, in order to translate the machine tool 1 in various directions, a high-power drive mechanism must be used, and furthermore, there is a problem that the machine tool 1 cannot be positioned at high speed. [0006] In addition, a hole is formed by laser beam irradiation,
The above problem also occurs in a laser processing apparatus that performs processing such as cutting or welding, and in a water jet processing apparatus that performs various processing using a water jet. The present invention solves this kind of problem, and performs a relative positioning operation between a work and a work quickly with a small driving force, and performs high-speed machining of various different works. The aim is to provide a possible working machine. [0008] In order to solve the above-mentioned problems, the present invention is directed to a method in which a spindle, which is a work , is moved in the axial direction.
A first member which is movably mounted, the pressure which is an object to be work product
Engineering product there is a substantially rectangular second member mounted, respectively turn individually handed to the first and second axis are parallel to each other Rutotomoni, the second axis is the workpiece through the turntable rotating the third axis that plug in exchange to. Thus, the relative positioning between the work and the work can be performed easily and quickly, and the work and the work can be arranged to be inclined with respect to each other. In addition, when the work and the work are positioned, the first and second members do not move in parallel, and it is possible to avoid the generation of inertia due to the movement of the center of gravity. Therefore, high-speed positioning is performed with a small driving force. [0010] Here, the first member mounts the main spindle, which is a work, so as to be able to advance and retreat in the axial direction thereof, and the second member mounts a work, which is a work. Therefore, it is possible to form a machining portion inclined at an arbitrary angle at an arbitrary position with respect to each surface of the workpiece, and for example, it is possible to efficiently perform an arc-shaped machining, a spiral machining, or the like. . FIG. 1 is a perspective view of a machine tool 10 according to an embodiment of the present invention. The machine tool 10 has a substantially cylindrical first mounting member (first member) 14 to which a main shaft 12 as a work is mounted, and a substantially rectangular shape to which a work W as a work is fixed. Second mounting member (second member) 1

The main shaft 12 is mounted on the main body 46, and a tool 48 is mounted on a drive shaft (not shown) in the main shaft 12. . In the state where the main body 46 is mounted, the position of the center of gravity of the first mounting member 14 is set on the X1 axis which is a dotted line during turning. The second support mechanism 20 includes a second support table 50 fixed on the base 26. On the upper part of the second support table 50, the X2-axis motor 52 and the second
A support shaft 54 is provided, and the second mounting member 16 is connected to the second support base 5 via the X2-axis motor 52 and the second support shaft 54.

The X2-axis motor 52 has the same configuration as that of the X1-axis motor 30, and the same components are denoted by the same reference characters and will not be described in detail. The third support mechanism 22 includes a rotary table 56 mounted on the second mounting member 16, and the rotary table 56 is rotatable around the Y axis via a rotary drive source (not shown). In the state where the work W is mounted on the rotary table 56, the position of the center of gravity of the second mounting member 16 is set on the X2 axis, which is the center line of rotation. The operation of the machine tool 10 thus configured will be described below. The machine tool 10 suitably functions particularly for processing a workpiece Wa such as a fan or a screw as shown in FIG. 4 or a workpiece Wb such as a scroll as shown in FIG. That is, when processing the work Wa, first, the X2-axis motor 5 constituting the second support mechanism 20 is used.

As a result, an arc-shaped groove 60 is formed in the work Wa through the tool 48, and the above-described operation is performed along a predetermined trajectory, whereby a work such as a fan or a screw as shown in FIG. Wa is formed. When machining a work Wb as shown in FIG. 5, first, under the driving action of the X2-axis motor 52,
