Abstract

The invention provides a magnetic composite fluid polishing device for the inner wall of a small thin pipe, and belongs to the field of polishing devices. The magnetic composite fluid polishing device for the inner wall of the small thin pipe comprises a support, a lead screw, polished rods, a polishing head support, a magnetic unit, a drive portion and a polishing portion. The polishing portion comprises a conveying pump, a magnetic composite fluid container and a workpiece seat. The output end of the conveying pump is connected to the magnetic composite fluid input end of a workpiece through a pipeline, the magnetic composite fluid output end of the workpiece communicates with the magnetic composite fluid container through a pipeline, the input end of the conveying pump is connected to the magnetic composite fluid container, and a complete loop is formed. In the device, a permanent magnet in the magnetic unit can rotate and can move left and right relative to the workpiece, and therefore a stable magnetic field can be generated, then Bingham fluid is formed by magnetofluid under the action of the magnetic field, shearing force is generated by the Bingham fluid, and the inner wall in an irregular shape of the workpiece is polished.

Description

technical field [0001] The invention relates to a polishing device, in particular to a magnetic composite fluid polishing device for the inner wall of a small thin tube, belonging to the field of polishing devices. Background technique [0002] At present, there are many ways to polish the inner wall of the pipe. Among them, the physical characteristics of fluid polishing are liquid and flow uniformly. It has been widely used in the field of irregular parts and inner hole polishing. Fluid polishing also has its limitations. When the abrasive medium passes through the channel, the amount of cutting at different parts of the channel is inconsistent. Magnetic composite liquid polishing is a new nano-scale ultra-precision processing technology. Under the action of a controllable magnetic field, the viscosity of the fluid can maintain continuous and stepless changes, and can achieve controllable and deterministic processing. The advantage of the controllable and variable size of...
