Multi-stage constant-speed self-circulation type magnetorheological polishing machine

Abstract

The invention discloses a multi-stage constant-speed self-circulation type magneto-rheological polishing machine which is used for polishing the inner wall of a pipe fitting and comprises a liquid inlet pipe, a magneto-rheological liquid accelerator, a threaded rotator, a liquid return pipe and magneto-rheological polishing liquid, and the magneto-rheological polishing liquid sequentially flows through the liquid inlet pipe, the threaded rotator, the pipe fitting and the liquid return pipe. The magnetorheological polishing liquid flows back to the liquid inlet pipe from the tail of the liquid return pipe, the magnetorheological liquid accelerator is arranged on the liquid inlet pipe in a sleeving mode, the threaded rotator is tubular, and internal threads are arranged on the inner side wall of the threaded rotator and used for enabling the magnetorheological polishing liquid flowing through the threaded rotator to rotate in the circumferential direction. The liquid return pipe is provided with at least one group of backflow control mechanism, each group of backflow control mechanism comprises a backflow coil and a backflow controller, the backflow coil is sleeved on the liquid return pipe, and the backflow controller is electrically connected with the backflow coil. And multiple polishing forms are formed, the inner wall of the pipe fitting is polished, the polishing efficiency is greatly improved, and in addition, it is guaranteed that the speed of the magnetorheological polishing liquid in the whole loop is the same.

Description

technical field [0001] The invention relates to a multi-stage uniform-speed self-circulating 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 adopting this principle all use water pumps as the flow driving components of the magnetorheological polishing fluid. The magnetorheological polishing fluid can only flow through the pipe fittings along a straight line at a constant speed for polishing. The polishing form is single and the polishing efficiency is low. Contents of the invention [0003] The p...
