DETAILED DESCRIPTION

[0020] 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.

[0021] Reference Figures 1 - 3, a grinding machine for a flange plate, comprising a flange plate body 1, a fixed frame 3 and a rotating frame 10. Two grinding discs 5 are installed on the fixed frame 3. A transmission shaft is rotatably installed on the fixed frame 3. The transmission shaft is connected to the two grinding discs 5 through a transmission mechanism. A grinding motor 4 connected to the transmission shaft is provided on the fixed frame 3. A rotating motor 9 is provided on the side of the fixed frame 3. A rotating frame 10 is installed on the output shaft of the rotating motor 9. A double-headed screw rod 11 is provided on the rotating frame 10 through an adjusting motor 12. A moving plate 13 is sleeved on the double-headed screw rod 11 in a threaded manner. An inner clamping plate 14 corresponding to the flange plate body 1 is installed on the moving plate 13.

[0022] The transmission mechanism includes transmission belt wheels 6 connected to the transmission shaft and the grinding discs 5. The two corresponding transmission belt wheels 6 are connected through a connecting belt 7. The grinding disc 5 also has an output shaft, and the output shaft rotatably penetrates the fixed frame 3. Two of the transmission belt wheels 6 are fixedly installed on the output shaft, and the other two transmission belt wheels 6 are fixedly installed on the transmission shaft.

[0023] A limiting rod 16 is provided on the rotating frame 10. The limiting rod 16 is parallel to the double-headed screw rod 11. The limiting rod 16 slidably penetrates the moving plate 13. The limiting rod 16 plays a role in limiting the moving plate 13 and can prevent the moving plate 13 from rotating together with the double-headed screw rod 11.

[0024] A protective pad 15 is provided on the surface of the inner clamping plate 14 in contact with the flange plate body 1. The protective pad 15 is made of rubber material, and anti-slip lines are provided on the surface of the protective pad 15. The rubber material and the protective pad 15 with anti-slip lines can first prevent the inner clamping plate 14 from damaging the surface in contact with the flange plate body 1, and secondly prevent the flange plate body 1 from sliding relative to the inner clamping plate 14.

[0025] A cylinder 2 is installed on the fixed frame 3. Lifting plates 8 are installed on both the cylinder 2 and the rotating motor 9. In this solution, after a plurality of components are combined together, they are hoisted and installed on the wall top of the processing workshop through the above two lifting plates 8.

[0026] The lifting plates 8 are welded to both the cylinder 2 and the rotating motor 9. The telescopic end of the cylinder 2 is also welded to the fixed frame 3. The protective pad 15 is adhesively connected to the inner clamping plate 14. Welding connection ensures connection stability, and adhesive connection facilitates tearing off and replacing the protective pad 15.

[0027] When the utility model is in use, the two inner clamping plates 14 are located inside the ring of the flange plate body 1. Start the adjusting motor 12 to drive the double-headed screw rod 11 to rotate. When the double-headed screw rod 11 rotates, the moving plate 13 will move, and the two moving plates 13 drive the inner clamping plates 14 to move away synchronously. Finally, with the cooperation of the protective pad 15, the inner extrusion fixation operation of the flange plate body 1 is realized. At this time, the installation of the flange plate body 1 is completed. Then start the cylinder 2 to drive the fixed frame 3 and other components to move closer to the flange plate body 1. Finally, it is Figure 1In the shown state, the upper and lower grinding discs 5 are in contact with the upper and lower end faces of the flange body 1. Immediately start the grinding motor 4. The grinding motor 4 drives the transmission shaft to rotate. The transmission shaft drives the grinding disc 5 to rotate by means of the belt pulley 6 and the connecting belt 7. The grinding disc 5 realizes the grinding process of the upper and lower end faces of the flange body 1. At this time, starting the rotation motor 9 can drive the rotating frame 10 to rotate. The rotating frame 10 drives the grinding disc body 1 to rotate relative to the grinding disc 5 to achieve a comprehensive grinding process.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
