Embodiment approach 1

[0026] Embodiment 1 Polishing of the inner cylindrical surface.

[0027] combine figure 1 , figure 2 , image 3 , when polishing the inner cylindrical surface, first fix the polishing workpiece (4) on the inner cylindrical surface in the polishing pool (2); then add an appropriate amount of magnetorheological fluid mixed with abrasives into the polishing pool (2); Then install the cylindrical polishing axis (3) on the two-coordinate control device (5), and adjust the distance between the polishing axis busbar (3a) and the polishing curved surface busbar (4b) by controlling the movement of the two-coordinate control device (5) in the XY direction Then turn on the magnetic field generating device (1), use the polishing axis (3) as one pole of the magnetic field, and arrange the other pole of the magnetic field evenly in the circumferential direction of the polished workpiece (4) to adjust the magnetic field force. Ensure that each point on the busbar (4b) of the polished cur...

Embodiment approach 2

[0028] Embodiment 2 Polishing of non-revolved surfaces.

[0029] combine figure 1 , figure 2 , Figure 4 , Figure 5 , the polishing axis (3) whose generatrix is ​​a straight line in Embodiment 1 is replaced with a special polishing axis whose generatrix function curve is consistent with the function curve of the polishing curved surface generatrix (3b). Since the linear velocity of each point of the polishing axis busbar is different, the magnetic field force at each point of the polishing curved surface busbar (4c) needs to be adjusted through the magnetic field generator (1), so that the grinding amount of each point of the polishing curved surface busbar (4c) is consistent. This ensures that the polished curved surface (4a) is uniformly polished, and the rest of the steps are exactly the same as those in Embodiment 1.

Abstract

The invention discloses a magnetorheological fluid curved surface polishing system which mainly comprises a magnetic field generating device, a to-be-polished workpiece, a polishing tank, a polishing shaft and two coordinate control devices. Under the control of the two coordinate control devices, the polishing shaft can perform self-rotation and move on an XY plane. The self-rotation of the polishing shaft drives a magnetorheological fluid flexible polishing head forming the semi-solid state under the action of magnetic fields to move relative to the to-be-polished curved surface of the to-be-polished workpiece, the magnetic field force applied to each point of the bus of the to-be-polished workpiece is adjusted through the magnetic field generating device to allow the polishing amount of each point of the bus of the to-be-polished workpiece to be consistent, and even polishing the to-be-polished workpiece can be performed until the required polishing precision is reached. The magnetorheological fluid curved surface polishing system is capable of polishing various inner and outer curved surfaces, small in roughness and high in surface evenness.

Description

technical field [0001] The invention mainly relates to the technical field of magnetorheological fluid polishing, in particular to a magnetorheological fluid curved surface polishing system for polishing various curved surfaces with magnetorheological fluid. Background technique [0002] The magnetorheological fluid will gradually change from a liquid state to a solid state under the action of a magnetic field, and its viscosity will gradually increase. Adding abrasives can form a semi-solid magnetorheological fluid flexible grinding head with many cutting edges. Magneto-rheological fluid polishing technology refers to that under the action of a magnetic field, when the semi-solid magnetorheological fluid flexible grinding head moves relative to the polishing surface of the workpiece, it will generate a large cutting force on the surface of the polishing surface, thereby polishing the polishing surface of the workpiece. polishing. Magneto-rheological fluid polishing technol...
