Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a vibration damping mount for semiconductor and optoelectronic dust free chamber, including floor support foot stool 1 and the damping device 2 of fixed mounting in floor support foot stool 1 top, support column 3 is installed to damping device 2's top, support column 3 is a cylinder structure, its top fixed welding has mounting platform 4, mounting platform 4 is a disc structure, mortise 31 has been seted up to support column 3's upper end, fixed mounting has crossbeam 6 in the mortise 31, crossbeam 6 is the stock that the cross-section is the rectangle, floor support foot stool 1's top fixed mounting has with heavy plate 5, through set up crossbeam 6 between support column 3, can improve vibration damping mount stability at the during operation greatly.
Furthermore, the rubber block 7 is fixedly installed at the bottom of the floor supporting foot seat 1, the rubber block 7 is of a cylindrical block structure, and the rubber block 7 is arranged on the lower surface of the floor supporting foot seat 1, so that abrasion between the shock absorption base and the ground due to vibration friction caused by the fact that the shock absorption base cannot absorb shock in hundreds of percent between the shock absorption base and a ground contact point can be effectively reduced, the influence of dust generated by the abrasion on a dust-free room is avoided, and the quality of products in the dust-free room is improved;
furthermore, the weighting plate 5 is a cuboid plate, circular notches are formed in four corners of the weighting plate, the notches are embedded with the damping device 2, the weighting plate is made of cast steel, the gravity center position of the damping base can be lowered by arranging the weighting plate 5, and the stability of the damping base during working can be further improved due to the lowering of the gravity center position;
