Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation support device such as a laser beam machine.

[0002]

2. Description of the Related Art FIG. 10 is an overall perspective view showing a laser beam machine installed in a factory such as a concrete floor. In the figure, reference numeral 9 is a table on which an object to be processed is placed, which has a structure movable in the X-axis direction. 1
Reference numeral 0 is a bed arranged on the floor surface via the support device portion 12, and 11 is a processing head portion. The processing head unit 11 is attached to a Y-axis driving unit and a Z-axis driving unit fixed to columns 15 fixed to both side portions of the bed 10, and
It has a structure that can move in the axial and Z-axis directions. Also,
Reference numeral 13 is a laser oscillator portion, and 14 is a control device portion including an operation panel.

Next, the processing method of the laser processing machine will be described with reference to FIG. First, a work to be processed is set on the upper surface of the table 9. Then, when the setting is completed, the laser beam is emitted from the laser oscillator 13 to the processing head unit 11.
Then, the table 9 is moved to the X-axis and the processing head portion 11 is moved in the Y-axis and Z-axis directions for processing. When the laser processing machine performs high-speed processing, particularly when the table 9 moves at high speed in the X-axis direction, a large inertial force is transmitted to the bed 10 when the table 9 is accelerated and decelerated, and the bed 10 receives a force that moves in the horizontal direction. receive. When the bed 10 moves, the displacement is transmitted to the column 15 fixed to the bed 10, so that the machining head portion 11 vibrates.

8 and 9 are cross-sectional views of a conventional installation and support device such as a laser beam machine. A device main body 3 such as a laser beam machine is supported by a leveling bolt 4 and hexagon nuts 5a and 5b screwed to the leveling bolt 4 in an adjustable height. Reference numeral 2 denotes a casting or iron receiving seat, which is placed on the floor surface 1 (for example, a concrete floor surface). A recess is provided in the center of the upper surface of the receiving seat 2, and the lower portion of the leveling bolt 4 is left stationary.

Next, a method for setting the level of the device body 3 will be described. A measuring device such as a spirit level is placed on the upper surface of the table 9 where the level of the device body 3 having the support structure as shown in FIG. The hexagon nut 5a screw-fitted to the leveling bolt 4 is loosened, and the hexagon nut 5b is rotated to vertically move the device body 3 to adjust the level. When the leveling of the device body 3 is completed, the hexagon nut 5a is fixed and tightened so that the hexagon nut 5b does not rotate. In this way, the work of setting the level of the device body 3 is completed.

[0006]

In the conventional simple installation method as described above, which is often adopted, the device body 3 is moved in the horizontal direction by the inertial force generated when the table 9 is accelerated and decelerated, for example. When receiving the force, the force was applied by the frictional force between the lower surface of the receiving seat 2 and the floor surface 1 due to its own weight. Therefore, when the moving force is larger than the frictional force, the device body 3 may move on the floor surface 1. As a result, the processing accuracy of the object to be processed may be greatly affected.

For this reason, when the processing precision is required to be more severe, the foundation bolt 7 is embedded in the concrete floor surface 1 as shown in FIG. And two hexagonal nuts 8a and 8b for foundation bolts were fixed to the device body 3 to prevent movement on the floor surface. However, this method may require enormous cost for installation work such as making a hole in the concrete floor surface 1 or fixing the foundation bolt 7 to the concrete floor surface 1 in accordance with the hole of the device body 3.

In addition to the above, for example, Japanese Patent Laid-Open No. 4-2
Although there is also 11196 “seismic pedestal structure” and the like, the recess formed on the upper surface of the receiving seat is configured so that the supporting leg of the device body slides in the recess, and the device body moves in the recess. Therefore, in the case of a laser processing machine or the like, the processing accuracy is reduced.

The present invention has been made to solve the above-mentioned drawbacks, and reliably prevents the supporting legs of the equipment body from moving on the floor surface, and improves the processing accuracy especially in the case of a processing machine or the like. Also, the support structure has a simple structure,
The purpose is to reduce the time required for installation work and to reduce the cost.

[0010]

An installation support device for a laser processing machine or the like according to the present invention is an installation support device for a laser processing machine or the like in which a supporting leg of a device body of the laser processing machine or the like is received by a seat. The upper surface of the receiving seat has a recess into which the lower end of the support leg is fitted, and the lower surface thereof has a pointed portion protruding downward.

In addition, in the installation support device such as a laser beam machine for supporting a device body such as a laser beam machine with a leveling bolt, the leveling bolt is formed with a pointed end protruding downward on a lower end surface which is in contact with the floor surface. It is a thing. In addition, the tip portion is formed by knurled unevenness.

Furthermore, in an installation supporting device such as a laser beam machine for supporting a device body such as a laser beam machine with a leveling bolt, there is a bolt penetrating the leveling bolt, and the bolt is a pointed tip protruding from a lower end of the leveling bolt. Parts.

[0013]

In the installation and support device such as the laser beam machine constructed as described above, even when receiving a force that moves in the horizontal direction due to inertial force of the main body of the device during normal operation, the support seat of the supporting leg is received. By providing a pointed portion protruding downward on the lower surface, frictional force with the floor surface can be exerted and horizontal movement can be prevented.

Further, since the head of the leveling bolt is provided with a pointed end, even when a force that moves in the horizontal direction due to the inertial force of the device body is applied, the pointed end exerts a frictional force with the floor surface, It is possible to prevent horizontal movement.

Further, a frictional force is exerted by the tip portion of the bolt penetrating the leveling bolt, so that the horizontal movement can be prevented.
