[0019] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0020] According to the instruction manual Figure 1-3As can be seen, when this utility model is in operation, the support plate 3, pressure plate 16, and grinding machine 11 are first selected according to the inner and outer diameters of the straight cylinder 4 to be processed, so that the continuous arc surface of the grinding roller 7 and the concave arc surface of the pressure plate 16 match the shape of the outer wall of the straight cylinder 4, and the arch of the support plate 3 matches the shape of the inner wall of the straight cylinder 4. One end of the support plate 3 is designed with a back plate 2, which is installed on the mounting plate 18 by the first screw 17. The pressure plate 16 is installed on the fixed plate 6 connected to the telescopic end of the cylinder 13 by the second screw 15. The grinding machine 11 is installed on the fixed frame 8 at the bottom of the moving end of the electric slide rail 9. After installation, the distance between the grinding roller 7 and the support plate 3 is the thickness of the straight cylinder 4. The grinding machine 11 is moved to the side close to the mounting plate 18 via the electric slide rail 9 on the bottom surface of the top horizontal plate 10, without affecting the installation of the straight cylinder 4. The operator places the welded straight cylinder 4 with weld scars onto the support plate 3, with the weld scars facing upwards and corresponding to the center position of the grinding roller 7 of the grinding machine 11. A pair of cylinders 13 are started, and the output end of the cylinders 13 drives the pressure plate 16 to press the straight cylinder 4 firmly onto the support plate 3 to maintain stability. At this time, the grinding machine 11 works, driving the grinding roller 7 to rotate. The electric slide rail 9 drives the grinding machine 11 to move and grind the weld scars on the weld seam of the straight cylinder 4. This invention uses a cylinder 13 to drive a pressure plate 16 to press the straight cylinder 4 onto an arched support plate 3. An electric slide rail 9 drives a grinding machine 11 to grind the weld scars. The pressure plate 16, the grinding roller 7 of the grinding machine 11, and the support plate 3 are designed according to the shapes of the outer and inner walls of the straight cylinder 4, ensuring the stability of the straight cylinder 4 and improving the grinding precision. Simultaneously, automated grinding also improves work efficiency.

[0021] The back plate 2 and the mounting plate 18 are detachably connected by the first screw 17. The telescopic end of the cylinder 13 is provided with a fixing plate 6. The pressure plate 16 is detachably connected to the fixing plate 6 by the second screw 15. The bottom of the moving end of the electric slide rail 9 is provided with a fixing frame 8. The grinder 11 is detachably installed in the fixing frame 8 by the third screw 12, so that the pressure plate 16, the support plate 3 and the grinder 11 can be replaced. It can be used to grind and process the weld seams of straight cylinders 4 with different diameters, which is highly practical.

[0022] Among them, the pressure plate 16 is provided with a rubber pad 5 on the side facing the straight cylinder 4 to increase the friction between it and the straight cylinder 4, ensure the stability during processing, and also avoid damaging the surface of the straight cylinder 4.

[0023] Among them, a limiting ring 19 is provided on the outer wall of the support plate 3 and at the position corresponding to the mounting plate 18. When installing the straight cylinder 4, the straight cylinder 4 is inserted until it reaches the limiting ring 19. At the same time, the limiting ring 19 also reserves a position for the grinder 11 to ensure the normal installation of the straight cylinder 4.

[0024] The upper surface of the pallet 3 has a mark at the center. When installing the straight cylinder 4, the weld seam should be aligned with the mark to ensure that the grinder 11 can grind the weld scar.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
