Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machining apparatus equipped with a multi-axis head, in which a part of tools can be changed in the spindle axis direction so as to correspond to a plurality of kinds of works.

[0002]

2. Description of the Related Art Conventionally, in a multi-axis head processing apparatus,
When processing two or more types of workpieces, it is general that, for example, separate transfer lines are arranged in parallel and processed by separate processing devices. This is because it is desirable to shorten the processing time at one processing station as much as possible from the viewpoint of mass production efficiency, and processing devices are provided in each transfer line according to the mode of the work.

[0003]

However, in recent years,
It is not always advantageous to provide a plurality of transfer lines from the standpoint of increasing the opportunities for various types of small-quantity production and improving the investment efficiency, and more efficient processing equipment has been desired.

[0004]

In order to solve such a problem, the present invention provides a cutting unit on a reciprocating slide table, and a plurality of spindle groups each having a plurality of spindles in the cutting unit. Rotation is transmitted from one rotary drive source to each spindle, and at least one of the spindle groups is movable back and forth in the spindle axis direction.

[0005]

The work is machined by each spindle by advancing the slide table. For a work of a certain type, for example, a part of the group of spindles is retracted to be machined by another spindle group or a work of a certain type. With respect to, the part of the spindle group is moved forward for processing. Therefore, the processing modes are diversified, and it is possible to process a plurality of workpieces of different types.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the combined machining apparatus of the present invention will be described with reference to the attached drawings. 1 is an explanatory view of the internal structure of the cutting unit, FIG. 2 is a front view of the apparatus, FIG. 3 is a partially enlarged view of FIG. 1, and FIG. 4 is an explanatory view of a rotation transmission mechanism.

The combined machining apparatus of the present invention is provided with a slide table 2 which is slidable in the direction perpendicular to the plane of the drawing (left and right in FIG. 1) along the slide guide 1 shown in FIG. Is provided with a cutting unit 3.

The cutting unit 3 includes a base frame 4 fixed to the slide table 2, a first spindle group 5 and a second spindle group 6 provided in the base frame 4, and each spindle group. The spindles 5 and 6 are respectively provided with a plurality of spindles.

That is, as shown in FIG. 2, the first spindle group 5 is provided with three spindles rotatable about the spindle axes a, b and c. At the tip, for example, the tools 7 and 8 shown in FIG.
These types of tools can be attached freely. As will be described later, the first spindle group 5 is movable in the spindle axis direction with respect to the base frame 4. Incidentally, FIG. 1 is an explanatory view for explaining the internal structure and the like of the cutting unit 3, and does not coincide with the plan view.

Further, as shown in FIG. 2, the second spindle group 6 is provided with six spindles which are rotatable around spindle shafts d, e, f, g, h and i. At the tips of d, e, f, g, h, and i, tools of the type such as tools 10 to 14 can be attached.

By the way, rotation is transmitted to each spindle from one drive motor 15 shown in FIG. 1 through a rotation transmission mechanism 16.

That is, the output shaft 15a of the drive motor 15
A drive gear 17 is attached to the drive gear 17, and a plurality of driven gears meshing with the drive gear 17 are further meshed with a plurality of idle gears to form a gear train, and in the middle of the gear train,
For example, in the case of the second spindle group 6, a shaft coupling 20 as shown in FIG.
The rotation transmission mechanism 16 as shown in FIG. 3 is configured to transmit the rotation to the spindles of the spindle axes a, b, c, d, e, f, g, h, and i.

Now, the structure of the first spindle group 5 will be described.

The first spindle group 5 is provided with a movable body 22 which can be moved back and forth by a cylinder unit 21 attached to the base frame 4.

In other words, the moving body 22 has a guide cylinder portion 23 slidable along a guide bar 27 fixed to the base frame 4 and a cylinder cylinder connecting portion 24 connected to the forward / backward driving cylinder unit 21. And a rotation transmission portion 25 that transmits a rotation force to the spindle, and a housing portion 26 in which a part of the gear train is incorporated,
As shown in FIG. 2, the guide bar 27 and the guide tube portion 23 are provided at two diagonally upper and lower positions.

As shown in FIG. 3, the cylinder rod 24 of the cylinder unit 21 is attached to the cylinder connecting portion 24.
The tip of 1a is connected, and therefore the cylinder unit 2
When 1 is operated, the moving body 22 moves back and forth along the guide bar 27. A stopper member 28 that restricts the forward movement position of the moving body 22 is attached to the base frame 4 so that the position of the stopper member 28 can be adjusted.

The rotation transmitting portion 25 is provided with a sliding cylinder 30 coupled to the housing portion 26, and a sliding bearing 31 for slidably bearing the forward / backward movement of the sliding cylinder 30 is attached to the base frame 4. There is.

A gear shaft 33, which is integral with the transmission gear 32, extends in the cylinder on the rear side of the sliding cylinder 30, and the rotary cylinder 34 is attached to a spline portion 33a provided on the outer periphery of the tip of the gear shaft 33. This rotary cylinder 34 is fitted with a spline.
Is connected to the rotary shaft 35. A spring 36 is provided between the rotary shaft 35 and the gear shaft 33.

Therefore, when the moving body 22 moves back and forth, the sliding cylinder 30 slides in the sliding bearing 31, and the rotary cylinder 34 also slides while being spline-fitted to the gear shaft 33. The rotation transmission function transmitted from the rotary shaft to the rotary shaft 35 is maintained.

A part of the gear train is formed in the housing portion 26 so that the rotational force received by the rotary shaft 35 can be transmitted to each spindle at the tip of the housing portion 26. .

An outline of the operation of the combined machining apparatus configured as described above will be described.

When the work W is positioned, the slide table 2 is moved forward for processing. For a work W, for example, the tools 7, 8 are retracted with the first spindle group 5 retracted. Then, only the tools 10 to 14 of the second spindle group 6 are used for processing.

Further, when processing other kinds of works W, the first spindle group 5 is moved forward for processing. In this way, by moving the first spindle group 5 forward or backward, the working mode can be made different, and two or more kinds of works W of different kinds can be processed.

[0024]

As described above, the combined machining apparatus of the present invention is
Since some of the plurality of spindle groups can be moved back and forth in the spindle axis direction, the processing modes are diversified and a plurality of types of workpieces can be processed by one transfer line. Therefore, capital investment becomes cheap and efficient processing is achieved.
