Vibration machine with electromagnetic vibration source

Abstract

The invention discloses a vibration machine with an electromagnetic vibration source. The electromagnetic vibration source for the vibration machine is composed of a static iron core, a movable iron core and an excitation coil, wherein the static iron core is connected with a base into a whole, and the movable iron core is connected with a worktable into a whole; a restoring assembly is formed by a restoring spring, a pressure adjustment screw and a restoring spring seat, and a vibration amplitude adjustment nut and a vibration amplitude adjustment screw can form a vibration amplitude adjustment assembly. By changing the vibration source, the vibration machine takes a motor as a power source instead of electromagnetism. As the transition process from motor starting to stop is eliminated, the vibration machine avoids vibration amplitude increase under the resonant condition of a mechanical system when the rotation speed of a rotary rotor is close to or equal to the inherent circular frequency of the system, can effectively control vibration time and vibration amplitude to keep flexible starting and quick brake, ensures that the vibration amplitude is consistent and stable in starting to brake process of the vibration machine, and is further suitable for operation environments and technical processes more strictly requiring vibration parameters.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment manufacturing, in particular to an electromagnetic vibration source vibration machine. Background technique [0002] It is known in the industry that during the manufacturing process of polycrystalline diamond compact drill bits and radial sliding bearings for screw drilling tools that are sintered with steel body, hard alloy, cast tungsten carbide powder and bonding alloy, The loaded cast tungsten carbide powder needs to be vibrated before being sintered with bonding alloy. In the construction engineering industry, the production of cement samples also requires a vibration process. At present, the vibration source of the vibrating machine used in the construction industry is a mechanical device. It is difficult to control the length of the vibration time and the vibration amplitude, and it cannot meet the vibration requirements of the powder in the sintering industry. Especi...
