Damping device and setting method thereof

Abstract

The invention discloses a shock absorbing device, comprising a main shock absorbing device, the two ends of the main shock absorbing device are provided with the shock absorbing device; the main shock absorbing device comprises a casing, the two sides of the pipe wall of the casing are symmetrical A travel groove is opened, and a first electromagnet and a second electromagnet are respectively provided at both ends of the inner sleeve, the first electromagnet and the second electromagnet are arranged coaxially, and the first electromagnet and the second electromagnet are arranged on the same axis. The polarities of the irons repel each other, the two side walls of the first electromagnet and the second electromagnet are symmetrically and fixedly connected with connecting rods matched with the stroke grooves, and the top and bottom ends of the sleeve are sleeved with sleeves. The connecting rods pass through the stroke grooves, and the connecting rods are all fixed to the connecting collars, the outer parts of the sleeves are sleeved with shock-absorbing springs, and two ends of the shock-absorbing springs are respectively connected with a ferrule. The invention utilizes the principle of repulsion of opposite sexes of electromagnets, and offsets the vibration energy through the repulsion force of the electromagnets, which can effectively reduce the vibration.

Description

technical field [0001] The invention relates to the technical field of damping, in particular to a damping device and a method for setting the damping device. Background technique [0002] Existing precision instruments in the industrial field often need to install various shock absorbers in order to avoid vibration. The existing shock absorbers include magnetic shock absorbers, but due to the defects of the permanent magnet technology at that time, the existing magnetic shock absorbers Most of them only rely on rubber materials to withstand power. The result of long-term use often causes rapid aging and failure of rubber due to frequent vibration forces, which in turn affects the service life of the equipment. [0003] For example, the patent number is 200720039409.X, the application date is June 6, 2007, and the invention patent named "Magnetic Shock Absorber" has a technical solution: set the upper magnet and the lower magnet according to the same sex, and the upper magne...
