A new type of vibration isolation pad for precision instruments

Abstract

The invention discloses a precise instrument vibration insulating pad which comprises an upper support alloy plate, a lower support alloy plate, a vibration insulating and energy absorbing container and middle coatings, wherein the upper and lower support alloy plates are arranged on the upper top surface and the lower bottom surface, and are made of a nickel-titanium shape memory alloy material; the vibration insulating and energy absorbing container is arranged between the upper support alloy plate and the lower support alloy plate, an air valve type liquid injecting hole is embedded in the vibration insulating and energy absorbing container; the middle coatings are adhered on surface connection parts of the upper and lower support alloy plates and the vibration insulating and energy absorbing container, and are made of a nano-material; oil liquid is injected into the vibration insulating and energy absorbing container. Compared with a traditional vibration insulating pad, the precise instrument vibration insulating pad is small and portable, can be changed in size to adapt to precise instruments of different sizes, has a very obvious insulating effect for high-frequency vibration, can well eliminate damage of high-frequency vibration to the precise instruments, and is also obvious in insulating effect for middle-frequency and low-frequency vibration.

Description

technical field [0001] The invention relates to a novel vibration isolation pad specially developed for precision instrument vibration isolation requirements, and belongs to the technical field of equipment vibration isolation. Background technique [0002] At present, under the environmental vibration in our country (such as the environmental vibration caused by the operation of the subway), the reading and writing pointers of some servers are aging too quickly, and the damage is serious, resulting in unnecessary waste; The problem of damage to precision instruments caused by a series of vibrations is particularly prominent. [0003] Traditional vibration isolation pads have a relatively single vibration isolation material, and are mainly used for seismic shock absorption of large buildings or equipment. The vibration isolation accuracy is low, and it cannot meet the vibration isolation requirements of precision instruments with higher precision. [0004] Existing vibratio...

Problems solved by technology

[0002] At present, under the environmental vibration in our country (such as the environmental vibration caused by the operation of the subway), the reading and writing pointers of some servers are aging too quickly, and the damage is serious, resulting in unnecessary waste; The problem of damage to precision instruments caused by a series of vibrations is particularly prominent

[0003] Traditional vibration isolation pads are relatively single vibration isolation materials, mainly used for seismic shock absorption of large buildings or equipment, and the vibration isolation accuracy is low, which cannot meet the vibration isolation requirements of precision instruments with higher precision

[0004] Existing vibration isolation pads are hardly developed for vibration isolation of precision instruments, especially high-frequency vibrations that are likely to cause damage to precision instruments. It is difficult to isolate and the effect is poor. The selection of materials and structural forms also lacks innovation and pertinence
