[0024] The following will refer to Figure 1-Figure 4 The invention of the utility model is described in detail in conjunction with the embodiments.

[0025] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a bottom-mounted magnetorheological polishing module integrated processing system, including a vacuum adsorption device 1, a magnetorheological polishing module 2, a magnetorheological fluid circulation system 3 and a gantry machine tool; wherein the gantry machine tool includes a bed 41, a workbench 42, a column 43, a beam 44, a saddle 45, a ram 46, and a turntable 47. The bed 41 is fixed to the ground through feet 48, the workbench 42 is installed on the bed 41, the number of columns 43 is two, which are respectively fixed on both sides of the bed 41, and the two ends of the beam 44 are respectively fixed between the two columns 43, and a guide rail is processed on the beam 44, and a slide is slidably matched on the guide rail. The saddle 45 is fixed on the slider, and the lateral movement of the saddle 45 on the beam 44 is achieved through the cooperation of the guide rail and the slider. The ram 46 is slidably connected to the saddle 45, and the ram 46 can move longitudinally along the saddle 45. The turntable 47 is fixed on the ram 46, and the turntable 47 is driven to move longitudinally by the ram 46. The vacuum adsorption device 1 is fixed on the turntable 47, and the turntable 47 includes but is not limited to the GSA-S series, GSA-L series, and GSA-H series. The vacuum adsorption device 1 is used to adsorb and fix the workpiece, and the workpiece is swung through the turntable 47, lifted and lowered through the ram 46, and moved transversely through the beam 44.

[0026] The vacuum adsorption device 1 includes a flange 11, a clamp 12 and a vacuum adsorption disk 13. The vacuum adsorption disk 13 is used for vacuum adsorption of workpieces. The axial part of the vacuum adsorption disk 13 extends into the clamp 12, and the vacuum adsorption disk 13 is clamped by the clamp 12. The clamp 12 is fixedly connected to one end of the flange 11, and the other end of the flange 11 is fixedly connected to one end of the turntable 47. The other end of the turntable 47 is connected to a connector 14, and the connector 14 is connected to a vacuum air pump (not shown) through an adapter 15. A vacuum air passage is formed inside the vacuum adsorption disk 13 and the flange 11, and a vacuum tube 16 is arranged in the vacuum air passage.

[0029] In existing magnetorheological polishing equipment, the workpiece is usually clamped and fixed by a block clamping device.

Therefore, the bottom-mounted magnetorheological polishing module integrated processing system provided by the utility model can improve the stability of magnetorheological processing, and is particularly suitable for the polishing of complex spherical, aspherical and free-form workpieces.
