Description

[Detailed description of the invention] The present invention is a vibration isolator for various machines that are sources of various vibrations, and at the same time, it is extremely easy to level the machines, etc. placed on the stand of the vibration isolator. This invention relates to a compression-type elastic vibration isolator that can be quickly adjusted with one touch.

In order for existing various types of vibration isolators to exhibit their vibration isolating functions with high efficiency, it is essential to always maintain the levelness of various machines that are sources of vibration, and it is also necessary to use appropriate vibration isolators. From the standpoint of exhibiting the performance of the machine itself placed above, it is an essential condition to keep the machine level. When adjusting the level, it must be done from the bottom end of the device or the surrounding area, and in practice, such horizontal adjustment work is extremely difficult when machines with appropriate weight are installed. This was an inconvenience.

Therefore, in conventional various compression type vibration isolators,
After placing the machine, etc. to be vibration-isolated on the vibration isolator, adjust the level by moving the machine slightly by hand to determine its center of gravity, or check the distance between the vibration isolator and the machine. The extremely unreasonable method of adjusting the level by interposing a spacer was used.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to extremely easily and quickly adjust the horizontal level of the machine from the top of the vibration isolator with one touch after the machine has been placed. The object of the present invention is to provide a compression-type elastic vibration isolator with a horizontal adjustment function that allows for horizontal adjustment at a low cost.

An embodiment of the present invention will be described below with reference to the attached drawings.

The drawing shows a longitudinal side view of a compression type elastic vibration isolator with a horizontal adjustment function according to the present invention,
The part that functions as a vibration isolator in the present invention includes caulking between an elastic vibration isolator 1 made of an elastic material such as rubber and protective plates 2 and 3 that sandwich the elastic vibration isolator from above and below. The vibration isolator structure can be applied to a wide range of loads from low loads to high loads by overlapping them with appropriate fasteners 4. The structure of the part that performs the horizontal adjustment function of machines etc. placed on the stand is such that a hole 5 is formed approximately in the center of the elastic vibration isolator 1 and the protective plate 2 on top of the elastic vibration isolator 1. A female screw body part 7 that engages with a lower male screw body 6 formed as a reverse screw is fixed to the hole of the plate 2, and the top of the lower male screw body 6 is provided with an appropriate screw plate into which a frame plate 8 can be fitted. In addition to providing a protruding portion 9, a female thread groove portion 11 that engages with an upper male thread body 10 formed as a normal thread is provided.

In addition, a nut part 12 for fastening a leg part 14 of a machine as appropriate is engaged with the upper male screw body 10, and a receiving groove part 13 for fitting an appropriate rotary tool is provided at the top of the nut part 12. is provided.

In this way, the present invention, which has the function of a vibration isolator as well as a horizontal adjustment function for machines installed on a pedestal, installs the legs 14 of the machine on the pedestal plate 8, and attaches them to the nuts. In actual use, the leg portions are fastened with the portions 12.

The machine on the mount plate is vibration-proofed with an elastic vibration isolator 1 made of an elastic material such as rubber, and horizontal adjustment of the machine is performed using a lower male screw body 6 and an upper male screw body. This is done by rotating with 10 or by upward movement. That is, the lower male screw body formed as a reverse screw is engaged with the female screw groove 11 of the lower male screw body, and the upper male screw body formed as a regular screw is rotated to the maximum rotational limit within the female screw groove. If the rotation continues above, the protection plate 2 will be rotated and moved upward via the female screw body 7, and as a result, the pedestal plate and the legs of the machine installed on it will be moved upward. It will move to an upper position.

Therefore, this invention was developed based on the practical need to adjust and maintain the level of the machine to be vibration-isolated as close to the floor as possible, so the lower part of the machine is After positioning the male screw body 6 at the lowest level, attach the legs of the machine to the pedestal plate, and after completing the attachment, rotate the upper male screw body 10 little by little as described above, and attach the legs to the pedestal plate at the same time as the lower male screw body. This is to adjust the level of the machine while raising the plate.

Of course, the above-mentioned horizontal adjustment is possible not only by rotating the upper male screw body but also by rotating the protrusion 9 provided at the top of the lower male screw body. Rotation allows not only horizontal adjustment in the flow of upward movement, but also horizontal adjustment in the flow of downward movement.

In addition, the compression type elastic vibration isolator according to the present invention is installed between the floor surface and the lower surface of the machine, increasing or decreasing the number of pieces installed depending on the load of the machine that is the source of vibration. Horizontal adjustment is performed as described above by using an appropriate number of vibration isolators.

According to the compression type elastic vibration isolator of the present invention, by simply rotating the upper male screw for horizontal adjustment from above the installed vibration isolator, it is possible to easily and quickly place the mount plate on the mount plate with one touch. The horizontal adjustment of the machine can be adjusted as close as possible to the floor surface due to the configuration of the above-mentioned proposal, and without increasing the cost. This is an extremely significant compression-type elastic vibration isolator that has succeeded in providing a horizontal adjustment function at low cost.
