Reciprocating type self-control rotating magnetic field magnetorheological polishing machine

Abstract

The invention discloses a reciprocating type self-control rotating magnetic field magnetorheological polishing machine. Two ends of a pipe fitting communicate with one end of a left liquid inlet pipe and one end of a right liquid inlet pipe correspondingly, a left magnetorheological fluid accelerator is arranged in the middle of the left liquid inlet pipe, and a left speed reducer is arranged at the end, away from the pipe fitting, of the left liquid inlet pipe; a right magnetorheological fluid accelerator is arranged in the middle of the right fluid inlet pipe, a right speed reducer is arranged at the end, away from the pipe fitting, of the right fluid inlet pipe, and the volume of the magnetorheological polishing fluid is smaller than the sum of the volume of the left fluid inlet pipe, the volume of the right fluid inlet pipe and the volume of the pipe fitting; and the rotating magnetic field mechanism is arranged on the outer side wall of the pipe fitting and used for enabling the magnetorheological polishing liquid flowing through the pipe fitting to rotate relative to the pipe fitting in the circumferential direction. The rotating magnetic field mechanism comprises a rotating magnetic field controller and a plurality of rotating electromagnetic coils, the rotating electromagnetic coils are fixed to the outer side wall of the pipe fitting and arranged along a spiral line, and the rotating magnetic field controller controls all the rotating electromagnetic coils to work. The magnetorheological polishing liquid reciprocates in the left liquid inlet pipe, the pipe fitting and the right liquid inlet pipe to polish the inner wall of the pipe fitting.

Description

technical field [0001] The invention relates to a reciprocating self-controlled rotating magnetic field magnetorheological polishing machine. Background technique [0002] It is already a common method to use magnetorheological fluid polishing liquid to polish pipes and objects with complex structures, especially for the inner wall polishing of some pipes. Magnetorheological polishing liquid can flow through thinner or inner walls with its liquid characteristics. The curved pipe is turned into a solid state under the action of a magnetic field, and the inner wall of the pipe is polished. However, the existing polishing equipment using this principle all use the water pump as the flow drive element of the magnetorheological polishing liquid, but the flow rate is constant and the water pump needs to be connected to the circulation channel, which affects the overall sealing performance, and the water pump is used as the power source. The magnetorheological polishing fluid can ...
