Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a variable adjustment mechanism that can freely select and fix the height and inclination of a base.

<Prior Art> Conventionally, there is a variable adjustment mechanism for a base etc. as shown in FIG. This variable adjustment mechanism is a bolt!
is passed through the base 2, and both sides of the base 2 are tightened with a height adjustment nut 8 and a tightening nut 9 that are screwed into the bolt I, thereby fixing the base 2 to the bolt I. The height of the base 2 is adjusted by adjusting the screwing position of the height adjustment nut 8 and the tightening nut 9 with respect to the bolt l, and the inclination of the base 2 is adjusted by installing the bolt l on the bottom plate 5. is being carried out.

<Problems to be Solved by the Invention> However, in the conventional variable adjustment mechanism described above, when the base 2 is tilted with respect to the base 10, as shown in FIG. A gap is created between the base 2 and between the tightening nut 9 and the base 2 according to the inclination of the base 2, which means that the height adjustment nut 8 and the tightening nut 9 are in uneven contact when the device is in operation. There are problems such as loosening of the height adjustment nut 8° and tightening nut 9 due to vibrations, etc., and damage to the base 2 and bolt 1 due to tightening of the tightening nut 9 in a uneven state. Further, in the conventional variable adjustment mechanism described above, the base 2 of the height adjustment nut 8 and the tightening nut 9 is
Since the inclination of the contact surface against the base 10 cannot be adjusted, there is a problem in that the bolt l must be mounted perpendicularly to the base 10 with high precision.

Therefore, an object of this invention is to be able to easily and arbitrarily select the height and inclination of the base, and to securely fix the base.
The purpose is to prevent damage to the base and the variable adjustment mechanism itself, and also to eliminate the need for vertically fixing the screw member with high precision to the base.

<Means for Solving the Problems> In order to solve the above problems, the variable adjustment mechanism of the present invention includes tightening the base with an adjustment nut having a spherical part and a tightening nut having a spherical part through a spherical ring. The basic feature is that by fixing the base, the inclination of the base can be freely selected in any direction, and uneven contact between the adjusting nut and the tightening nut can be prevented. More specifically, the variable adjustment mechanism of the present invention includes an adjustment nut having a spherical surface, and a spherical surface having a spherical surface at one end that slidably fits into the spherical surface of the adjustment nut, and a flat surface at the other end. a ring, a tightening nut having a spherical part, a spherical ring having a spherical part at one end that slidably fits into the spherical part of the tightening nut, and a flat part at the other end; and a spherical ring passing through the spherical ring. At the same time, the adjustment nut and the screw member screwed into the tightening nut are provided, and the flat parts of the spherical rings are brought into contact with both sides of the base, respectively, and the base is tightened with the adjustment nut via the spherical ring. It is characterized by being fixed by tightening it with a nut.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In Fig. 1(a), Fig. 1(b), and Fig. 2, ■ is a bolt as a screw member installed on the bottom plate 5, 2 is a base penetrated by bolt l, and 3 is a screw threaded into bolt l. The combined mounting is an adjustment nut for adjusting the height, 6.7 is a spherical ring that is penetrated by the bolt 1 and holds the base 2 from both sides, and 4 is a tightening nut screwed onto the bolt 1.

The upper part of the adjustment nut 3 is provided with a concave spherical part 3a, while the lower part of the spherical ring 6 is provided with a convex spherical part 6a that slidably fits into the spherical part 3a of the adjustment nut 3.
has been established. The spherical portions 3 a, 6 a have a radius of rotation R about the center of rotation 0.

It is. The upper end surface of the spherical ring 6 is a flat portion 6b, and this flat portion 6b is in close contact with the lower surface of the base 2. The hole 6c at the center of the spherical ring 6 is made large enough to allow the spherical ring 6 to freely tilt without coming into contact with the bolts l.

The lower part of the tightening nut 4 is provided with a convex spherical part 4a, and a concave spherical part 7a which is slidably fitted into the spherical part 4a of the tightening nut 4. The spherical portions 4a and 7a have a rotation radius RI around the rotation center O. The lower end surface of the spherical ring 7 is a flat portion 7b, and this flat portion 7b is in close contact with the upper surface of the base 2.

The hole 7C at the center of the spherical ring 7 is made large enough to allow the spherical ring 7 to freely tilt without coming into contact with the bolt 1. Further, the hole 2a of the base 2 is also sized to provide a certain clearance between the base 2 and the bolt 1 so that the base 2 can be tilted with respect to the bolt 1.

In the above configuration, when it is desired to fix the base 2 at an inclination angle θ with respect to a plane perpendicular to the bolt l, the spherical ring 6 is attached while the flat part 6b is brought into close contact with the base 2 according to the inclination angle θ of the base 2. The adjustment nut 3 is rotated on the spherical part 3a with a rotation radius R3 around the rotation center 0, and the spherical ring 7 is rotated with a rotation radius R1 around the rotation center O while the flat part 7b of the spherical ring 7 is brought into close contact with the base 2. The base 2 is fixed to the bolt 1 by rotating the spherical portion 4a of the tightening nut 4 at an inclination angle θ and tightening the adjusting nut 3 and the tightening nut 4. The height of the base 2 is adjusted by changing the mounting position of the adjustment nut 3.

In this way, the spherical ring 6.7 has its flat parts 6b, 7
Since it can be rotated along the spherical surface part 3a of the adjustment nut 3 and the spherical surface part 4a of the tightening nut 4 while holding the base 2 in close contact with the base 2, the inclination of the base 2 can be set arbitrarily.
Moreover, uneven contact does not occur in the base 2, the spherical ring 6.7, the adjusting nut 3, and the tightening nut 4, and damage to them is prevented.

FIG. 3 shows an example in which bolts l are fixed to the base 10 by welding. In this case, as in the case of surface description, even if the base 2 is tilted, there will be no uneven contact, in other words, the base 2 will not touch the base 2 reliably without any gaps.
can be fixed, and the height and inclination angle can be adjusted arbitrarily. Furthermore, since the inclination angle can be adjusted arbitrarily in this way, highly accurate verticality is not required when fixing the bolt 1 to the base 10, and the bolt l can be easily fixed.

<Effects of the Invention> As is clear from the above, the variable adjustment mechanism of the present invention has the following effects:
Since the base is tightened and fixed via a spherical ring with an adjustment nut having a spherical part and a tightening nut having a spherical part, the inclination of the base can be freely selected in any direction, and the adjustment nut and It is possible to prevent the tightening nut from hitting unevenly, so the base can be securely fixed, and
It can prevent damage to the base, screw members, adjustment nuts, tightening nuts, etc. Also, when fixing the screw member to the base,
Verticality is no longer required, and screw members can be easily fixed.
