Abstract

PURPOSE:To make a moving mechanism and a moving space of a table unnecessary, and to make a device small-sized by moving a work along on a table fixed to a bed, and also moving a head along an arm overhanged to the upper side of the table. CONSTITUTION:A work W is held by a clamp pawl 6' of a clamper 6 provided on a saddle 5, on a table 4 fixed to a bed 1 of a device A. As for the saddle 5, an intermal thread a' in its inside is engaged to a ball screw S2, therefore, the ball screw S2 rotates by rotating a motor forward and backward, and the saddle fixed to the internal thread a' moves the work W in the left and right directions of the device A. Subsequently, when a plasma head 7 is moved along an arm 3 in the front and rear directions of the device A, the work W can reach a desired working point. Next, the work W is brought to plasma working along an optional curve by a plasma torch held by the plasma head 7.

Description

[Detailed Description of the Invention] This invention is an apparatus for cutting or drilling metal and non-metal materials using energy such as light, electrons, gas flame, etc., which requires a small installation area and space, and has high precision. ,
The aim is to obtain equipment with streamlined maintenance.

Taking a plasma device as an example of one of the conventional cutting and drilling devices of this kind, it has a plasma head fixed in a fixed position, and a table above the bed of the device that is installed at the back of the bed. The workpiece (workpiece such as a steel plate) held by the saddle on this table moves left and right (moves in the X-axis direction) to perform the required machining of the workpiece. The dot is placed in the plasma and below the dot.

However, in such a conventional device, the table itself, which occupies a relatively large portion, moves in the Y-axis direction, making the device as a whole large in size. However, this method requires a large amount of space, requires a mechanism to move such a large table, and has the disadvantage that it is difficult to maintain its accuracy.

Furthermore, in such a conventional device, in order for the table having the saddle mechanism for moving the workpiece to move forward and backward in the YIll11 direction as described above, the operator must move the column lt+ of the device.
11, which is inappropriate as a position from which to view the entire apparatus, and is often inconvenient for operations such as inserting a workpiece.

The device of this invention was devised to solve these problems, and by using a mechanism that keeps the table above the bed stationary and moves the plasma head in the Y-axis direction, the device as a whole is small in size. As a result, the installation floor area and space for the equipment were significantly reduced.

Embodiments of the present invention will now be described with reference to the drawings, and a plasma cutting and drilling apparatus will be described by way of example.

Figures 4g1 and 2.3 show the entire apparatus (A) of this invention, with a column (2) at the back end of the bed (1).
An arm (3) is provided at -L thereof, extending perpendicularly to the bed (1) and extending approximately to the front end of the bed (1). A table (4) is fixed on the table (4), and a workpiece (W) is held on this table (4) by the clamp claw (6) of the clamper (6) provided on the saddle (5). and move on the table (4).

As shown in Fig. 6, a plasma head (7) is installed on the arm (3) so as to move in the front-rear direction (in the Y-axis direction) along the arm (3). A ball screw Sl for moving the plasma head (7) having the plasma head (7) is provided in the Y-axis direction, and the plasma head (7) is connected to the
The internal screw (a) fixed in the support body (8) of the head (7) is screwed together, and the plasma head (7) is moved to a desired position in the Y-axis direction by a drive motor M. Note that (E) in Figure 1 shows the plasma current generator, (C) in Figures 1 and 5 shows the control box, S2 is the ball screw for moving the saddle (5), and M2 is the saddle drive. The motor for - is.

As shown in Fig. 4, a female thread (al) is installed inside the saddle (5), and a table (
4) is screwed into the ball screw S2 installed along the line. This ball screw S2 is driven by a saddle drive motor M2.

Next, the action of the device (A) of this invention will be described. Placement (A) On the table (4) fixed to the head (1), there is a workpiece (B) held by the clamp claw (61) of the clamper (6) provided on the saddle (5). is the internal female thread (a5 is the ball screw S)
, so by rotating the drive motor M2 in the forward and reverse directions, the ball screw S2 rotates, thereby moving the saddle (5) fixed to the female screw (a) to the workpiece (b). is appropriately moved in the left-right direction (X-axis direction) of the device (A).

Next, the plasma head (7) is moved along the arm <3) in the front-rear direction (Y-axis direction) of the device 71 (A). That is, by rotating the motor M1 in either the forward or reverse direction, the ball screw S rotates, and the internal screw (a) fixed thereto is in the support (8) of the plasma head (7) that engages with it. Since it moves, the plasma head (7) can move appropriately in the longitudinal direction (Y-axis direction) of the apparatus (A) and reach a desired processing point on the workpiece (B). The plasma torch (7) held by the plasma head (7) can thereby perform plasma processing on the workpiece (b) along an arbitrary curve.

The device of this invention integrates the bed and table and fixes the table to the bed and column, and unlike conventional devices, the large table itself does not need to be moved.
By completely eliminating the need for a mechanism for moving the table and the space required for the table to move, the entire device can be significantly miniaturized, and by eliminating the cost and maintenance required for them, the mechanism can be simplified. , which makes it easier to maintain accuracy and saves labor.
This can greatly contribute to rationalization.

In addition, the operator's position can be located at the center of the front of the equipment, allowing him to see the whole area, allowing him to load and unload workpieces,
For some companies, it is easy to remove and this greatly contributes to improving work efficiency.

Note that the device of the present invention is similarly applicable to devices that utilize energy such as lasers and gas flames.
