Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-tasking machine having both functions of round and box machining.

[0002]

2. Description of the Related Art In general, metal workpieces are classified into a round workpiece which rotates a workpiece and fixes a tool, and a box workpiece which fixes a workpiece and rotates a tool to process. An ordinary lathe is the former machine tool for processing a round product, and a box product cannot be gripped by a chuck rotated by a main shaft, and a box product is processed exclusively by a machining center. For this reason, conventionally,
In order to process both round and box workpieces, it was necessary to install two machine tools, a lathe and a machining center.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a combined machining machine capable of machining a round workpiece and a box workpiece with one machine tool.

[0004]

In order to solve the above-mentioned problems, a multi-tasking machine according to the present invention comprises a headstock having a chuck capable of holding and rotating a workpiece, a table on which the workpiece is placed, The tool rest includes a turret for attaching a turning tool and a rotary tool, and a slide mechanism that supports the tool rest so as to be slidable in three orthogonal axes. Here, it is possible to provide a fixed table, but preferably,
The table may be provided slidably (claim 2). Further, the table may be rotatably provided (claim 3).

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, in the multitasking machine of this embodiment, a bed 2 is installed on a leg 1, and a headstock 3 is fixed to the front of the left end of the bed 2. The headstock 3 has a spindle 4 with a motor 5
And a chuck 6 for gripping a round workpiece RW (see FIG. 3) is attached to the tip of the main shaft 4. In addition, a table 7 on which a box workpiece BW (see FIG. 3) is placed is slidably moved left and right in parallel with the main shaft axis by a guide 8 on the front of the right end of the bed 2 and its upper surface (YZ plane). Are formed with a plurality of T-shaped grooves 9 for attaching a fixing jig (not shown).

A first saddle 11 is provided on the upper surface of the bed 2 by a guide 12 so as to be slidable in the Z-axis (left and right) directions.
A triangular second saddle 13 is supported on the first saddle 11 by a guide 14 so as to be slidable in the Y-axis (front-back) direction. At the front of the second saddle 13, an intermediate base 15 is provided so as to be slidable in the X-axis (up and down) directions by a guide 16, and a tool rest 17 is assembled to the intermediate base 15. A turret 18 is supported on the tool rest 17 so as to be rotatable around an axis extending in the Y-axis direction. A turning tool 19 and a rotary tool 20 are attached to two positions of the turret 18 at 180 ° apart. 20 is determined by 90 ° in accordance with the turning of the turret 18.

The first saddle 11 and the second saddle 13
A slide mechanism that supports the tool rest 17 slidably in the three orthogonal directions of Z, Y, and X from the and the base 15 is configured. Therefore, as shown in FIG.
Side, and the round workpiece RW is turned by the turning tool 19.
Can be turned, and as shown in FIG.
Is positioned on the table 7 side, and the box workpiece BW can be milled or bored by the rotary tool 20. In FIG. 1, 23 is an automatic tool changer, 24 is a change arm, 25 is a tool magazine, 26 is a control box, 27 is an operation panel, and in FIG. 2, 28 is a chip conveyor.

Incidentally, as the table, in addition to the sliding table 7 described above, a rotary table 21 as shown in FIG. 1 can be used. The turntable 21 is provided on the bed 2 so as to be rotatable around a vertical axis. According to this, there is an advantage that five-sided processing of the box workpiece BW can be performed. In addition, the present invention is not limited to the above-described embodiment, and can be embodied by appropriately changing the shape and configuration of each part without departing from the spirit of the present invention.

[0009]

As described in detail above, according to the multi-tasking machine of the present invention, the tool post is provided so as to be slidable in three orthogonal directions between the headstock and the table. This provides an excellent effect that a round workpiece and a box workpiece can be machined.
