Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a turret machine tool that processes a workpiece by pre-installing different types of tools and selectively using them. This invention relates to a turret machine tool that is capable of machining multiple workpieces at the same time.

<Prior Art> Conventionally, different types of cutters were attached to a cutter support stand one by one, and a workpiece was processed by selectively using these.

For this reason, only one workpiece was required to be machined, and mass productivity was poor.

<Problems to be Solved by the Invention> In the present invention, a large number of heads that rotatably support a cutter are attached in parallel to a slender, cylindrical head support, and the required head is selected by rotating the support. The purpose of this is to create a turret machine tool that is capable of machining many workpieces at the same time and is highly productive in mass production.

<Means for Solving the Problems> In order to achieve the above object, the present invention is constructed as follows.

That is, a cylindrical head support that is located above the workpiece support and extends in the horizontal direction is provided, and a rotation device that rotates the head support around a horizontal axis is provided to rotate the head support. A plurality of heads for rotationally supporting the cutter are provided on the outer periphery in a radial and horizontal direction, and a moving device is provided for moving the workpiece support in the X-axis and Y-axis directions.

<Function> Since the present invention has the above-mentioned configuration, a plurality of heads directed toward the workpiece support table by the rotating device face the workpiece support table. Therefore, a large number of workpieces mounted on the workpiece support stand facing each of the heads are processed simultaneously.

In this case, each head can rotate around the horizontal axis, and the workpiece support can move in the X-axis and Y-axis directions, so workpieces can be machined not only in two directions, but also on inclined surfaces. is also possible.

Note that if the head support stand or the workpiece support stand is moved in the Z-axis direction, processing in the Z-axis direction in addition to the above is also possible.

<Example> Hereinafter, an example in which the above configuration is embodied will be described based on the drawings.

In the drawings, FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a right side view thereof.

Reference numeral 1 denotes a machine base, and a Y-axis relay 3 is mounted on the front part of the machine base 1 via an X-axis rail 2 so as to be slidable in the front and rear directions.

The above-mentioned X-axis relay 3 is an
It is moved back and forth by a shaft servo motor 4.

A Y-axis relay 6 is placed on top of the X-axis relay 3 via a Y-axis rail 5 so as to be slidable in the left-right direction.

The Y-axis servo motor 7 provided at the left end of the Y-axis servo 6 moves the Y-axis servo 6 in the left-right direction.

The Y-axis relay 6 extends in the left-right direction, and a workpiece support 8 is placed on the upper surface thereof. This workpiece support stand 8 is constructed as follows.

That is, a headstock 9 extending in the left-right direction is mounted and fixed on the rear part of the Y-axis shiray 6, and a rotating shaft 10 that projects forward is mounted on the headstock 9 and extended in the left-right direction 6.
Provided in individual pitches. These rotating shafts 10 are connected to a headstock servo motor 1 provided on the Y-axis servo 6 via a worm and a worm gear (not shown).
1 allows for synchronous rotation within a 360 degree range.

Further, six tail stocks 12 are mounted and fixed at the front part of the Y-axis relay 6 at equal pitches. A push shaft 13 is rotatably provided on each of these tail stocks 12 so as to face each of the rotation shafts 10.

Each of the push shafts 13 is moved in the front-rear direction by a lever 14 provided on the right side of each tail stock 12.

Furthermore, a flat table 15 is removably placed and fixed on the upper surfaces of the head stock 9 and tail stock 12.

Next, a column 16 is fixed upright at the rear of the machine base 1, and a Z-axis sill 18 is provided on the upper front part of the column 16 via a Z-axis rail 17 so as to be slidable in the vertical direction. The Z-axis servo motor 19 provided on the column 16 moves the Z-axis servo motor 19 in the vertical direction.

A cylindrical head support 20 is disposed horizontally, that is, in the left-right direction, at the front of the Z-axis relay 18, and is attached to be rotatable about the left-right axis.

The head support stand 20 is connected to a rotating device 21 provided at the right end of the Z-axis sill 18, that is, a head support stand servo motor 22, a worm 23 connected to the rotating shaft of the servo motor 22, and the right end of the head support stand 20. It is rotationally driven by a worm gear 24.

A large number of heads 25 are attached to the outer periphery of the head support base 20, arranged horizontally at six locations and radially at six locations. Further, the pitch of each head 25 in the horizontal direction is equal to the pitch corresponding to the rotation axis 10 described above.

Each of these heads 25 has an independent motor (not shown) and a quick chuck 26 connected to the motor for rotation.

The six quick chucks 26 arranged in the horizontal direction are all fitted with blades of the same shape (not shown), and the quick chucks 26 adjacent to each other in the circumferential direction are each fitted with blades of different shapes (not shown).

Here, the aforementioned X, Y, Z axis servo motors 4, 7, 19 and headstock servo motor 1
1. The head support servo motors 22 are each driven and controlled by instructions from a separately provided numerical control panel (not shown).

In addition, 27 in the figure is a cylinder type balancer that suspends the Z-axis relay 18.

Next, the operation of the above embodiment will be explained.

First, a workpiece is attached to the workpiece support stand 8.
In this case, when machining the outer circumferential surface of the rod-shaped workpiece, the table 15 is removed and the workpiece is placed between each rotary shaft 10 and each push shaft 13, respectively.

Then, set the type and initial position of the cutter to be attached to each head, and turn on the start switch (not shown).
Press.

Then each head 2 on the side facing the worker
5 rotates, and each servo motor 4, 7,
19, 11, and 22 are driven and controlled by receiving preprogrammed commands from a numerical control panel, and six rod-shaped workpieces are processed in parallel at the same time.

In addition, when processing, for example, a plate-shaped workpiece (not shown) that does not need to be rotated, the table 15
Attach the six workpieces to the upper surface of the table 15, and press the start switch as described above.

Then, each head on the side facing the plate-shaped work rotates, and each servo motor 4, 7, 19, 22 except the stock servo motor 11 rotates.
receives pre-programmed commands from a numerical control panel, and the workpieces are machined simultaneously.

<Effects> Since the present invention is configured as described above, it has the following effects. (1) Since the workpiece is supported in two states, rotating and non-rotating, in addition to cutting the outer peripheral surface of a rod-shaped workpiece, it is possible to perform completely different types of machining, such as machining a plate-shaped workpiece. (2)
Since a plurality of blades are placed to face each workpiece on a workpiece support table that rotates and supports a plurality of workpieces, a plurality of workpieces can be processed in parallel at the same time.
