[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Figures 1 to 7 An embodiment of the polishing machine with a grabbing and automatic unloading function of the present invention is shown, comprising a frame 1, a clamping mechanism 2, a polishing shaft 3 and an unloading mechanism 4, wherein the clamping mechanism 2, the polishing shaft 3 and the loading mechanism 4 are mounted on the frame 1 from bottom to top, a plurality of polishing heads 5 are mounted on the polishing shaft 3 along the circumferential and axial directions, the unloading mechanism 4 comprises an unloading rack 41, a moving rack 42, a moving driving member 43 and a plurality of rows of grabbing mechanisms 44 for grabbing the polishing sheets on the polishing heads 5, the unloading rack 41 is mounted on the frame 1, the moving rack 42 is slidably mounted on the unloading rack 41, each row of grabbing mechanisms 44 is mounted on the moving rack 42, the moving driving member 43 is mounted on the unloading rack 41 and drives the moving rack 42 to drive the grabbing mechanisms 44 to move to positions corresponding to the corresponding polishing heads 5. When the polishing sheet on the polishing head 5 needs to be replaced, the polishing machine is stopped, the moving drive member 43 is started, and the grabbing mechanism 44 is driven to move to the position corresponding to the corresponding polishing head 5, and then the grabbing mechanism 44 is actuated to grab the polishing sheet on the polishing head 5, so as to realize automatic unloading, clamp the part on the clamping mechanism 2, and the polishing head 5 on the polishing shaft 3 polishes the part. Compared with the traditional structure, the unloading device realizes the automatic unloading of the polishing sheet, has a simple structure, saves time and labor, and improves production capacity and efficiency; in addition, it avoids the erroneous operation of not unloading the sheet when manually unloading the sheet, and ensures the accuracy of unloading the sheet.

[0027] In this embodiment, the moving driving member 43 is configured as a cylinder.

[0028] In this embodiment, the gripping mechanism 44 includes a gas source seat 441, a pair of slides 442, and a clamping claw 443 installed on the slide 442. The gas source seat 441 is fixed on the mobile frame 42 and is connected to external gas. The pair of slides 442 are slidably mounted on the gas source seat 441 and drive the clamping claw 443 to clamp and grasp the polishing sheet on the polishing head 5. In this structure, the gas introduced will drive the clamping claw 443 to close along the slide 442 to achieve the clamping and grasping action of the polishing sheet. When the clamping claw 443 is unfolded along the slide 442, the polishing sheet is released and falls, thereby realizing the automatic unloading of the material by gripping.

[0029] In this embodiment, a protective cover 45 for covering the moving frame 42, the moving drive member 43 and the grabbing mechanism 44 is installed on the unloading frame 41. The protective cover 45 plays a protective role on the moving frame 42, the moving drive member 43 and the grabbing mechanism 44.

[0030] In this embodiment, the protective cover 45 is provided with an escape hole 451 for the extension of the clamping claw 443. The escape hole 451 can ensure that the clamping claw 443 is extended to achieve the clamping and grasping action.

[0031] In this embodiment, a water baffle plate 46 for sealing the avoidance hole 451 is installed on the protective cover 45, and the clamping claw 443 is penetrated on the water baffle plate 46. The water baffle plate 46 seals the avoidance hole 451 to prevent external cooling water and dirt from entering the protective cover 45 from the avoidance hole 451.

[0032] In this embodiment, the protective cover 45 is also provided with a stopper 47 for driving the polishing sheet on the clamping jaw 443 to peel off. When the movable driving member 43 drives the clamping jaw 443 to retract, the polishing sheet will hit the stopper 47, thereby driving the polishing sheet on the clamping jaw 443 to peel off, and the structure is simple and ingenious.

[0033] In this embodiment, a track 411 is provided on the unloading rack 41, and the moving rack 42 is slidably mounted on the track 411. The provision of the track 411 ensures the smoothness of the moving rack 42 when moving.
