Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a work table, and more specifically, the present invention relates to a work table, and more specifically, a suitable number of tubes that penetrate almost perpendicularly through a base supporting the work table are fixed to the base. The threaded parts of a suitable number of supporting legs attached to the lower end of the work table and having a threaded part at the other end are inserted into the pipe body while maintaining an appropriate gap, and A work table in which a spherical part of the same sphere is provided, a spherical washer corresponding to the spherical part is provided, and a support leg is provided so as to be adjustable in elevation and swing via nut members that press the spherical washers to the spherical part at both ends. It is related to.

b. Prior Art For example, the work tables 3, 3 (shown in FIG. 3) of the blanking shear 1 shown in FIG.
Many free ball bushes on the top surface (not shown)
are held on the base 5 by, for example, four supporting legs 7 at the same level and spaced apart from each other.

A carriage base 13 is provided between the left and right work tables 3, 3 mentioned above, which straddles the left and right guide rails 9, 9, and is screwed onto the lead screw 11 so as to be movable and positionable in the Y-axis direction (see Fig. 2). be.

A carriage 15 (see Fig. 2) that can be moved and positioned freely in the X-axis direction (see Fig. 3) and a workpiece gripping claw device 17 are provided on the carriage base 13. 1
9 and the lower blade (not shown).

The blanking shear 1 is a shearing machine that cuts two pieces with upper and lower shearing blades that are perpendicular to each other to cut out a small rectangle or the like. In this case, the work tables 3, 3 serve as supports to prevent both ends of the large plate material in the X-axis direction from sagging.

The work table 3 in the above example is supported by a plurality of supporting legs 7 from a base 5 at a distance in the X-axis direction, and is a central work table on a central base 21 that supports the guide rails 9, 9 described above. The pass line that is aligned to the same level as 23 and is the top surface of the lower blade
Must occupy the position of PL.

Conventionally, alignment was achieved by adjusting all the bolts at the lower ends of the plurality of support legs 7 mentioned above.

c. Problems to be solved by the invention As is already clear from the above, adjustment of conventional work tables has the disadvantage of being complicated and requiring a lot of man-hours.

d Means for solving the problem In this invention, spherical parts are provided on the upper and lower walls of the tube that is installed almost perpendicularly to the base, and the supporting legs can be raised and lowered and swung freely relative to the tube through spherical washers. The work table has an adjustable configuration that makes adjustment of the work table simple and easy.

e Function As is already clear from the above explanation, since the supporting legs can be raised and lowered and swung freely, it is possible to easily deal with twisting of the base, which was difficult to adjust in the past, and the number of adjustment steps can be reduced. I got a work table.

f Embodiment In FIG. 1, a tube 25 that penetrates the base 5 almost vertically is attached to the base 5 by suitable means such as welding.

A threaded portion 27 is machined on the other end of the support leg 7 attached to the lower end of the work table 3, and the threaded portion 27 is inserted into the tube body 25 with an appropriate gap 29 maintained therebetween.

Further, spherical portions 31 of the same sphere (diameter D) are provided on the upper and lower end tube walls of the tube body 25, and spherical washers 33, 33 corresponding to the spherical portions 31 at both ends are screwed into the threaded portion 27. The spherical parts 31, 31 are crimped to the spherical parts 31, 31 by nut members 35, 35.

g Effect of the invention As can be understood from the above explanation, by adjusting both the upper and lower nut members 35, 35, the effective length of the supporting leg 7 can be adjusted to be longer or shorter. Use a spanner etc. to attach the supporting leg 7.
When the screw portion 39 is rotated, the work table 3 is slightly raised and lowered by the screw portion 39.

Further, since there is a gap 29, the support leg 7 can swing freely around the center of the same sphere (diameter D).

Thus, the work table of the present invention has the effect that even if the left and right work tables are far apart, it is easy to adjust them to the same level as the central work table.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it is clear that design changes can be easily made without departing from the technical idea.
