Abstract

PURPOSE:To suppress the bending of a bed and also disperse the load applied to a floor surface by three-point supporting with a support means such as a fixed type jack bolt etc. after the level of a machine is adjusted, and moreover supporting a machine main body with a floatable type (spring type etc.) supporting means. CONSTITUTION:A machine main body is three-point supported at three positions on a floor surface with a fixable type (unfloatable type) support means A of a jack bolt type or leveling block type after a machine level is adjusted. Moreover floatable type support means B of a spring type or fluid pressure type are suitably arranged considering the variation etc. of the bending of a bed 1 due to the transfer of a weight on the bed 1. This arrangement enables a fixed support part to be supported with force in an unfloatable range, bending to be reduced, and the machine to be constrained in the minimum bending to be safely supported.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for stationary support of machine tools, industrial machines, and other various machines, instruments, and devices on a floor surface.

[Conventional technology]

Examples of supporting means conventionally used to support machines, devices, etc. on the floor include a jack bolt type shown in FIG. 1, and a leveling block type shown in FIG. 2.

In FIG. 1, reference numeral 1 denotes the bed of the machine, which is supported and fixed on the floor by jack bolts 2, nuts 3, and supports 4.

The ped 1 is supported by adjusting the level of the bed by the action of jack bolts 2 and nuts 3, and then fixing the bed 1 to the floor surface.

In addition, in Fig. 2, the slider 5 is arranged so as to be able to slide on the inclined surface a of the support 6, and by the operation of the relevel adjustment bolt 7, the slider 5 moves the slider 5 onto the inclined surface a on the support 6. Move along the machine, adjust the level of bed 1 on the machine, and then move ped 1.
is fixed to the floor.

[Problem to be solved by the invention]

By the way, it is common for machines to be supported on the floor using support means such as leveling blocks or jack bolts at four or more locations, but it is difficult to use all four or more support locations effectively. Adjustment is extremely difficult, and gaps may be created in the support portion due to the movement of heavy objects on the machine, which may adversely affect machining accuracy. In order to eliminate this drawback, there are conventional machines that are supported at three points, which can be said to be a highly stable support method.
When supporting a bed with the same weight and the same rigidity, there is a problem that the smaller the number of support points, the greater the deflection.

The support method of the present invention has been proposed with the aim of solving the above-mentioned problems.

[Means to solve the problem]

For this reason, the method of supporting machine tools, etc. of the present invention is basically to support the machine at three points using a jack bolt type or leveling block type support means that can be fixed after adjusting the level of the machine (non-floating type), and then In addition to this, a floating type spring-type or hydraulic support means is used in combination, and this is placed at a position where the amount of deflection of the bed is large, thereby supporting the machinery and suppressing the deflection of the bed. It is said that

(Function) In the above-mentioned method for supporting machine tools, etc. of the present invention, the level of the machine is adjusted and fixed by the non-floating type supporting means shown in FIG. 1 or FIG. 2, and then the heavy object on the bed is moved. In consideration of changes in the deflection of the bed due to changes in the deflection due to cutting force, etc., floating support means as shown in FIG. 3 or FIG. Since the machine is supported with a force within a range that does not cause it to float and deflection is reduced, the machine can be stably supported with minimal deflection, allowing smooth movement of each element on the machine and improving machining accuracy.

〔Example〕

The method for supporting machine tools, etc. of the present invention will be explained below with reference to the drawings. Figure 1 is a side sectional view of the jack bolt type support means used in the present invention, Figure 2 is a side sectional view of the same leveling block type support means, and Figure 2 is a side sectional view of the same leveling block type support means. 3 is a side sectional view of the same spring-type support means, FIG. 4 is a side sectional view of the same hydraulic support means, and FIG.
The figure shows an example of the relative arrangement of each support means in the method of the present invention.

In the supporting method of the present invention, first, the bed 1 of machine tools and other various devices, etc.
, the receiver is a jack-bolt type support means made of gold 4 or a second
Using a leveling block type support means consisting of a slider 5, an abutment 6, and a bolt 7 as shown in the figure, support parts are set at three appropriate locations and the levels are adjusted and fixed.

In the case of Fig. 1, the height of the machine is adjusted with bolts 2 and fixed with nuts 3.

In the case of FIG. 2, the height of the machine is adjusted by sliding the slider 5 with the bolt 7 and using the slope a of the support 6.

Next, take into consideration changes in the deflection of the bed due to the movement of heavy objects on the bed, deflection due to cutting force, etc.
By arranging a floating support device as shown in the figure at an appropriate location, it is possible to suppress the deflection of the bed and reduce the negative effect on the precision of the workpiece.

In FIG. 3, the support rod 8 that supports the bed 1 is the support stand 1.
) is supported by support bolts 9 via springs 10. The supporting force can be adjusted by adjusting the height of the support bolt 9 by rotation. After adjustment, fix with nut 12.

In FIG. 4, the bed 1 is supported by the rod 13 disposed inside the cylinder 14 by the fluid pressure supplied into the cylinder 14 through the fluid pressure joint 16, so the supporting force can be increased by changing the fluid pressure. Can be adjusted.

15 is Patsukin.

The supporting means shown in FIGS. 3 and 4 are both floating type and the supporting force can be adjusted, so that even if the number of supporting means used is increased as necessary, each supporting means can function effectively. By increasing the number of units used, the load on the floor will be dispersed and overload on the floor can be eliminated.

FIG. 5 shows the relative arrangement of the support means, A shows the non-floating type support means with three points support, and B shows the position of the floating type support means arranged accordingly.

〔Effect of the invention〕

As described above, according to the supporting method of the present invention, the following effects can be obtained.

(1) It is possible to reduce the deflection of the bed, smooth the operation of the device, and improve the precision of the workpiece.

(2) Since multiple units can be used, the load on the floor can be reduced and foundation construction costs can be reduced.
