Problems solved by technology
[0003] Existing shock absorbers are generally made of rubber, such as a kind of rubber shock absorber with inclined plane force described in Chinese utility model patent CN200520062240.0. There is a large difference in shock absorption in different directions, and the pressure bearing direction is single, which makes it difficult to meet the high index shock absorption requirements in six directions during the transportation of precision equipment

specific Embodiment
[0014] Combine Figure 1 to Figure 6 , The present invention includes four groups of flexible units 1, an upper plate 2 and a lower plate 3 arranged in a cross. The cross arrangement structure is as Figure 4 Shown. The flexible unit 1 is connected to the upper plate 2 through the upper planes of the pressure-bearing block 11 and the pressure-bearing block 12, and is connected to the lower board 3 through the pressure-bearing block 14 and the lower plane of the pressure-bearing block 15.
[0015] The flexible unit 1 is composed of connecting blocks 16, 17, pressure-bearing blocks 11, 12, 14, 15 and a number of rubber blocks 13. The connecting block 17 is connected to the rubber block 13 through two inclined surfaces, and each inclined surface is connected as required. ~3 rubber blocks 13, the rubber block 13 is made of corrosion-resistant and aging-resistant rubber material, and its function is to withstand the load weight of the mechanical equipment transmitted from the upper pl...

The invention provides a vibration absorber for a precise mechanical equipment, which comprises four groups of flexible units in cross layout. An upper plate and a lower plate are respectively connected with an upper contact surface and a lower contact surface of the four groups of flexible units to form an interlayer structure; the flexible unit comprises four pressure bearing blocks, a plurality of rubber blocks and two double bevel connecting blocks in X-shape layout. Therefore, due to simple structure, average and balanced stress for the symmetric structure of two layers, stable rigidity for the cross arrangement structure for the flexible unit, the invention has excellent vibration isolation effect in six directions.
Description
Technical field [0001] The invention relates to the field of mechanical shock absorption, in particular to a shock absorber for precision mechanical equipment. Background technique [0002] Precision mechanical equipment has strict technical requirements for shock and vibration during transportation. If the shock and vibration exceed the equipment's bearing capacity, it will affect the performance and even destroy the accuracy of the equipment. [0003] Existing shock absorbers are generally made of rubber material. For example, the inclined plane force rubber shock absorber described in the Chinese utility model patent CN200520062240.0 has a single-layer shock-absorbing rubber block with a small shock-absorbing range. There is a big difference in damping properties and a single pressure bearing direction, which makes it difficult to meet the high-index damping requirements in six directions during transportation of precision equipment. Summary of the invention [0004] In order to...
