They are a substitute for similar pneumatic products.

[0003] The patent document with publication number "CN220217751U" discloses a precision flexible grinder device for anti-theft doors. Through the cooperation of the flexible grinding device and the lifting device, the conveyor belt transports the anti-theft door, and the downward movement of the moving box drives the grinding disc to move downward, so that the soft pad contacts the surface of the anti-theft door, and the first motor drives the connecting plate to rotate, and the rotation of the connecting plate drives the limit rod to drive the grinding disc to rotate.

[0004] In the prior art, during the grinding process of the security door, the security door is rubbed and polished by the high-speed rotation of the grinder. Since the surface of the security door is uneven and the grinding discs are mostly fixedly installed horizontally, there are places that the grinding equipment cannot reach, resulting in poor grinding effect. At the same time, the security door is fixed by external clamping, which is easy to cause damage to the security door. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 3 A precise flexible grinding machine device for anti-theft doors comprises a mounting frame 1 and a fixed plate 8, wherein the fixed plate 8 is fixedly connected to the inner wall of the mounting frame 1, and the fixed plate 8 is slidably connected to a movable plate 15.

[0024] A grinding component is installed on the movable plate 15, and the grinding component includes a sleeve 11, a square block 12, a disc 13, a grinding disc 16, and a second spring 14. The two sleeves 11 are fixedly connected to the two ends of the movable plate 15 respectively, and a square groove is opened in the sleeve 11. The square block 12 is slidably connected in the square groove, and the disc 13 is slidably connected to the lower end of the square block 12. Therefore, when the servo motor 10 drives the sleeve 11 to rotate, the sleeve 11 can drive the square block 12 to rotate, and the square block 12 can slide up and down in the sleeve 11 at the same time. The grinding disc 16 is rotatably connected to the disc 13, and the grinding disc 16 is hinged to the lower end of the square block 12. The second spring 14 is fixedly connected between the movable plate 15 and the disc 13. The grinding component also includes a servo motor 10 and a screw rod 2. The screw rod 2 is rotatably connected between the two ends of the fixed plate 8. The movable plate 15 is threadedly connected to the screw rod 2, and can drive the movable plate 15 to move horizontally when the screw rod 2 rotates.

[0025] A protrusion 4 is fixedly connected to the mounting frame 1, and a slide plate 5 is slidably connected to the protrusion 4. A plurality of first springs 7 are fixedly connected to the upper end of the slide plate 5, and a placement plate 6 is fixedly connected between the ends of the plurality of first springs 7 away from the slide plate 5. A rack plate 18 is fixedly connected to the lower surface of the placement plate 6, and a plurality of suction cups 3 are fixedly connected to the placement plate 6. Two suction cups 3 are respectively fixedly connected to a connecting cylinder 17, and a rotating shaft 9 is rotatably connected between the two connecting cylinders 17. The rotating shaft 9 is provided with teeth, and the rotating shaft 9 is meshed with the rack plate 18. Pistons 19 are respectively slidably connected in the two connecting cylinders 17, and the two pistons 19 are respectively threadedly connected to the two ends of the rotating shaft 9. The connecting cylinder 17 and the piston 19 are both elliptical in shape, so that when the rotating shaft 9 rotates, the piston 19 can be driven to slide horizontally in the connecting cylinder 17.

[0026] In the utility model, when in use, first pull the slide plate 5 and slide it on the protrusion 4, so that the placement plate 6 is away from the mounting frame 1, and the anti-theft door is placed on the placement plate 6. The placement plate 6 moves downward under the gravity of the anti-theft door and compresses the first spring 7. At this time, the anti-theft door is fitted with the suction cup 3, and as the placement plate 6 moves downward, the rack plate 18 can be pushed downward, and the rack plate 18 can drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it can drive the two pistons 19 to move in the center, and make the connecting tube 17 have a negative pressure, so that the suction cup 3 can be tightly adsorbed on the surface of the anti-theft door, so as to achieve rapid fixation of the anti-theft door without causing damage to the anti-theft door.

[0027] At the same time, when the rotating screw 2 rotates, it can drive the movable plate 15 to move horizontally, and the movable plate 15 can drive the servo motor 10, the sleeve 11, the square block 12 and the grinding disc 16 to move horizontally. Therefore, when the servo motor 10 drives the sleeve 11, the square block 12 and the grinding disc 16 to rotate, the anti-theft door can be polished in a larger range. The grinding disc 16 is tightly in contact with the surface of the anti-theft door under the elastic force of the second spring 14. Therefore, when encountering an uneven anti-theft door, the grinding disc 16 will fit the surface of the anti-theft door. At the same time, the grinding disc 16 is connected to the square block 12 through a universal adapter, so the grinding disc 16 can achieve various square inclinations to achieve better grinding effects.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
