Description

Technical Field

[0001] The utility model relates to the field of electromagnetic vibration tables, and in particular to an electromagnetic vibration table with adjustable magnetic suction force. Background Technique

[0002] The vibrating table body is also called a vibration generator, and its working principle is as follows: the moving part of the vibrating table body, that is, the moving coil, when an electric current passes through its coil, according to the "Fleming" left-hand law, the coil with current will generate motion in a constant magnetic field, pushing the moving coil and the tabletop to move, thereby generating an exciting force. By changing the magnitude and direction of the current, the magnitude of the exciting force and the moving direction of the tabletop can be changed. The main components of the vibrating table body include: moving coil, table body, machine base, trunnion vibration isolation system, support airbag, excitation coil, guiding system, etc.

[0003] Chinese Patent discloses an electromagnetic vibration with adjustable magnetic suction force (authorized publication number CN215278365U). This patented technology discloses an electromagnetic vibration table with adjustable magnetic suction force, including a base and an operating table arranged at the upper end of the base. Magnetic suction control mechanisms are arranged on both sides of the base, a clamping mechanism is arranged at one end of the operating table, a cleaning mechanism is also arranged at one end of the operating table, L-shaped plates are arranged on both sides of the base, a concave groove is opened on one side of the L-shaped plate, a convex block is opened on one side of the concave groove, a telescopic rod A is arranged on one side of the convex block, and the telescopic rod A is connected to one end of the L-shaped plate. An electromagnetic block is arranged at one end of the convex block. When the electromagnetic vibration table is working, the telescopic rod A expands and contracts, and the electromagnetic block moves up and down along with the telescopic rod A under the action of the convex block and the concave groove. By changing the distance between the electromagnetic block and the operating table, the effect of controlling the magnetic suction force is achieved, thereby solving the problem that the magnetic suction force is inconvenient to adjust. This patented technology solves the problems that when the existing electromagnetic vibration table is working, its magnetic suction force remains unchanged, which is inconvenient to control. When an object is on the operating table, it is easy to shake, making it inconvenient to perform electromagnetic vibration on the object, and foreign objects are easily contaminated on the operating table, which is inconvenient.

[0004] However, after long-term use of the existing technology, it is found that when the electromagnetic vibration table is working, the electromagnetic block is vibrated and generates a force on the telescopic rod A, resulting in a shortened service life of the telescopic rod A and the need for regular replacement, which is a waste of resources.
