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] Referring to FIGS. 1 to 6 , the present invention includes four groups of flexible units 1 arranged in a cross, an upper plate 2 and a lower plate 3 , and the structure of the cross arrangement is shown in FIG. 4 . The flexible unit 1 is connected to the upper plate 2 through the upper planes of the pressure-bearing blocks 11 and 12 , and connected to the lower plate 3 through the lower planes of the pressure-bearing blocks 14 and 15 .

[0015] The flexible unit 1 is composed of connection blocks 16, 17, pressure blocks 11, 12, 14, 15 and several rubber blocks 13. The connection block 17 is connected to the rubber blocks 13 through two slopes on it, and each slope is connected to 2 ~3 rubber blocks 13, the rubber blocks 13 are made of corrosion-resistant and aging-resistant rubber materials, and their function is to bear the load weight of the mechanical equipment transmitted by the upper plate 2 and buffer the impact vibration. The two slopes of the connecting block 17...

Abstract

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 precision mechanical equipment shock absorber. Background technique [0002] Precision mechanical equipment has strict technical requirements for shock and vibration during transportation. If the shock vibration exceeds the bearing capacity of the equipment, it will affect the performance of the equipment and even destroy the accuracy of the equipment. [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. Contents of the invention [0004] In order to meet the demand for ...
