The machinery installation block set is configured as described above.

[D. How to Use] Next, how to use this machine installation block set will be described. [D-1. Addition of basic block to basic block)
(Refer to FIG. 5 and FIG. 6) The operation of adding the basic block 1 and adding the block 31 is performed as follows. First, the basic block 1 is added and placed on the block 31. At this time, the orientations of the basic block 1 and the extension block 31 are shifted from each other by approximately 60 ° in the circumferential direction as shown in FIG. It is made to relatively fit inside the flange 21c. Thereby, the step 17 of the basic block 1 rides on the upper surface of the fitting projection 41, and the engaging flange 41 a of the extension block 31 is located at the same height as the engaging groove 23 of the basic block 1.

From this state, the basic block 1 is rotated horizontally by approximately 60 °. This rotation is performed until the slope 8 of the basic block 1 and the corner side 7 ′ of the extension block 31 are aligned vertically. Thereby, the foot 21 of the basic block 1 is extended and rides on the footrest 43 of the block 31, and the engaging flange 23 of the block 31 is engaged with the engaging groove 23 of the basic block 1. In this manner, the extension block 31 is joined to the lower side of the basic block 1 in an extended manner, and the total effective height of the basic block 1 and the extension block 31 is 2 h (100 mm).

When connecting the basic block 1 and the extension block 31, the screw holes 25 formed in the feet 21 of the basic block 1 are extended and face the push screw engagement holes 41 b of the block 31. In order to do this, when the basic block 1 is added and placed on the block 31, it is preferable to select the orientation so that the screw hole 25 is located beside the push screw engaging hole 41b as shown in FIG.

From the state where the basic block 1 and the extension block 31 are connected in this manner, a push screw 61 (see FIG. 7) is screwed into the screw hole 25, and the tip is inserted into the push screw engaging hole 41b. Crimp. Thus, the rotation of the basic block 1 and the extension block 31 is prevented.
Therefore, the basic block 1 and the extension block 31 are integrally connected to each other without shifting in any of the vertical and horizontal directions.

[D-2. The operation of extending the extended blocks 31 is performed in exactly the same manner as the operation of extending the basic blocks 1 and extending the blocks 31. That is, the extension block 31 is placed on another extension block 31 so as to be displaced from each other by approximately 60 ° in the circumferential direction, and the step 17 ′ of the upper extension block 31 is placed on the lower extension block 31. 31 is put on the upper surface of the fitting projection 41. Then, from this state, the upper extension block 31 is rotated approximately 60 degrees horizontally (rotated until the respective corner side surfaces 7 'of the upper and lower extension blocks 31 are aligned vertically), and the foot 21' is put on the footrest. 43 and engaging groove 2
The engagement flange 41a is engaged with 3 '. In this case, the screw hole 25 ′ of the upper extension block 31 is opposed to the push screw engagement hole 41 b of the lower extension block 31. Then, the push screw 61 is screwed into the screw hole 25 ', and the tip is crimped to the push screw engaging hole 41b. As a result, the two extension blocks 31 are integrally connected to each other without being displaced in any of the vertical and horizontal directions. The total effective height of the two connecting blocks 31 thus connected is 2 h (100 mm).
become.

[D-3. Installation of Machinery] (Refer to FIG. 7) When installing the machinery, whether to use only the basic block 1 or the extension block as the installation block depends on the height required for the installation block. select. For example, if the required height of the mounting block is 5
When about 0 mm is enough, only the basic block 1 is used, and the mounting legs 65 of the machine are inserted into the mounting leg insertion holes 15 of the basic block 1. An extra or insufficient dimension for the height required for the machinery is adjusted by an adjustment mechanism provided on the installation leg 65.

If the height required for the basic block 1 and the adjustment by the adjusting means are not enough, for example, the required height of the mounting block is 100 mm or 150 mm, as shown in FIG. One or more extension blocks 31 are added to the basic block 1 and used. In this case, too, the installation legs 65 of the machinery are also used.
Into the mounting leg insertion hole 15 of the basic block 1 and extra dimensions or required dimensions for the required height are:
The adjustment is performed by an adjustment mechanism provided on the mounting leg 65.

[D-4. (See FIG. 9) In the case where the extension block 31 is extended to form an installation block, when the installation blocks are likely to be displaced from each other due to vibration applied to the machinery, the connection bracket described above is used. Using 51 or the like, the mounting blocks are connected to each other.

FIG. 9 shows an example in which the machine 71 is installed with four installation blocks 73 positioned so as to occupy each corner of the rectangle. The connection bracket 51 has a main plate 53 attached to the bottom surface 21 b of the basic block 1. This mounting is performed in such a manner that the arm plate 55 faces the inside of the virtual rectangle connecting the four mounting blocks 73 in sequence. Then, the four connection brackets 51 are arranged such that adjacent ones and ones that face each other diagonally are
Each is connected by a connection plate 75.

The connecting plate 75 is obtained by cutting a so-called flat steel into a required length and forming bolt holes at both ends. The adjacent connecting brackets 51 are connected to the connecting plate 75 by using the bolt through holes 55b of the arm plate 55, and the connecting brackets 51 that face each other diagonally are connected to one end side bolt through hole 53a of the main plate 53. Are connected to the connection plate 75 by using. Thus, the four mounting blocks 73
Since each is connected to three installation blocks 73, it has sufficient seismic strength.

The work of connecting the installation blocks 73 in this manner is preferably performed before the machine 71 is installed on the installation block 73. In addition, addition block 3
When two or more 1s are added to form the installation block 73, the above-described connection can be provided in a plurality of upper and lower stages.

In this embodiment, only one set of the screw holes 25 and (25 ') for passing the rotation preventing bolt 57 and the push screw engaging hole 41b is provided.
(25 ′) If the push screw engagement holes 41b are provided corresponding to all three feet, it is not necessary to worry about the orientation when the blocks are joined.

A basic block 81 according to another embodiment will be described with reference to FIGS. Since the basic block 81 has the same components as the basic block 1, the same components are denoted by the same reference numerals used in the description of the basic block 1, and the description thereof will be omitted, and only the differences will be described. The upper surface 83 of the basic block 81 has an area larger than the upper surface 3 of the basic block 1, and a concave portion 85 is formed in the upper surface 83. The concave portion 85 is formed in a columnar shape having a small height, and has a bottom 87.

The recess 85 accommodates a pad 89 as an elastic body for the vertical direction, and the pad 89 is provided on the bottom 87. The pad 89 is made of hard urethane, is formed in a disk shape, and its peripheral surface is stored in contact with the inner peripheral surface 91 of the concave portion 85. Reference numeral 93 denotes a steel cup, and the cup 93 is manufactured to have a shape and size that can be accommodated with a slight clearance (about 0.5 mm) in the inner peripheral surface of the recess 85. An installation leg insertion hole 95 is formed on the upper surface of the cup 93, and an O-ring fitting groove 97 is formed on the outer peripheral surface of the cup 93.
Are formed. An O-ring 99 is fitted in the O-ring fitting groove 97 as a circumferential elastic body made of synthetic rubber.

The cup 93 is accommodated in the recess 85 and is set on the pad 89. That is, the pad 89 is the cup 9
3 and the bottom 87 of the recess 85. The O-ring 99 is in contact with the inner peripheral surface of the recess 85. That is, the O-ring 99 is disposed between the outer peripheral surface of the cup 93 and the inner peripheral surface 91 of the recess 85.

The basic block 81 is used in the same manner as the basic block 1. That is, the basic block 81 may be used alone, or may be used by engaging with the extension block 31. Further, the connection bracket 51 may be attached and connected to another basic block 81 via the connection plate 75. The operation and effect of the basic block 81 are the same as those of the basic block 1 except for the points described below.

A description will now be given of a method of use and effects specific to the basic block 81. As shown in FIG. 11, the installation leg 65 of the machinery is inserted into the installation leg insertion hole 95 of the cup 93 and held by the cup 93. The vibration generated when the machinery is driven is transmitted to the cup 93 via the mounting leg 65, but the vertical vibration is absorbed by the pad 89,
The vibration in the circumferential direction (the direction in which the mounting leg 65 falls) is O
The vibrations of the machinery are suppressed by being absorbed by the ring 99. Therefore, for example, when polishing or boring is performed with high accuracy, it is possible to prevent machining irregularity caused by chatter (small vibration) caused by resonance between the machine body and the cutting blade,
The occurrence of defective products can be prevented. Therefore, the basic block 81 is particularly effective when applied to machines that perform precision machining.

In the basic block 81, the O-ring 9
9 is elastically in contact with the inner peripheral surface of the recess 85, so that the cup 93 is held in the recess 85,
Can be prevented from accidentally coming off. Further, if cups having mounting leg insertion holes of different sizes are prepared, installation legs of various thicknesses can be accommodated only by replacing the cup alone.

Although the embodiment of the present invention has been described in detail, the specific configuration is not limited to this embodiment, and there is a change in design without departing from the gist of the present invention. Are also included in the present invention. In particular, in the embodiments, the present invention has been described as a set including a basic block, an extension block, and a connecting bracket, but the present invention can be implemented with only one type of block. For example, if the installation leg insertion hole 15 is formed on the upper surface of the “reinforcement block” 31 in the embodiment shown in the drawings, the extension block alone may be used alone or in a plural number to have a required height. A mounting block can be configured.

Further, the structure of the engaging portion and the shape of the connecting bracket in the present invention are not limited to those shown in the embodiment, and the foot does not necessarily have to be provided. Also, the means for stopping rotation is not limited to bolts. In the above embodiment, the connection bracket is manufactured by welding the main plate and the arm plate. However, the connection bracket may be manufactured from a single member by sheet metal working. Further, in the above-described embodiment, an example in which one connection bracket is attached to the basic block has been described. However, both the basic block and the extension block, or a plurality of multi-tiered extension blocks, each have a connection bracket. May be attached, and a wide (thick) connecting plate straddling the plurality of connecting brackets arranged in the vertical direction may be attached. In this case, higher connection strength can be obtained.

In the above other embodiments, the pad 89 is made of hard urethane and the O-ring 99 made of synthetic rubber is used. However, the present invention is not limited to this, and can absorb vibration. As long as it is a material, any material such as another synthetic resin may be used, and a metal spring or the like may be used. Further, the pad 89 is not limited to a disk shape, and may be a square plate shape or any other shape.

As described above, in the machine installation block according to the first aspect of the present invention, a single block or a plurality of blocks are stacked to obtain an approximate height, and a height that is insufficient or surplus is obtained. If the height is adjusted by the adjusting means of the machinery, it will function as a mounting block of the required height without any problem. Therefore, according to the present invention, the height can be freely set while keeping the rated specification.

According to the second aspect of the present invention, no special member is required to perform the engagement, and the work for engaging is only a light work, and the upper and lower engagement states are reliably maintained. .

According to the third aspect of the present invention, since the block is installed at three points, it can be stably grounded even in a place having a slight inclination or unevenness, and further, the lower engagement is provided inside the three legs.
