[0035] like Figure 6 As shown, the end of the mounting shaft 11 has a built-in ejector pin hole 13, which can be adapted to traditional ejector pin clamping grinding.

[0036] Furthermore, a tail cover 5 is provided at one end of the roller 1, and a through hole 54 is provided in the middle of the tail cover 5. The tail cover 5 is detachably connected to the support cylinder device 2. The tail cover 5 is used to seal the support cylinder device 2, providing stable sealing performance, preventing water and slag from entering the support cylinder device 2 during the grinding process, and ensuring the stable operation of the bearing 9.

[0037] Furthermore, the support device 2 has a third circular hole 21, a fourth circular hole 22 and a fifth circular hole 23 sequentially opened inside. The inner diameter of the fourth circular hole 22 is smaller than the inner diameter of the third circular hole 21 and the fifth circular hole 23.

Then, the set screw 8 is rotated continuously until its end abuts against the mounting shaft 11, thus pushing the support device 2 off the mounting shaft 11 for disassembly. The circumference of the mounting plate 6 is also evenly distributed with several eighth connecting holes 63, and a handle 7 is threaded into the eighth connecting holes 63.

[0040] In this utility model, the two ends of the connecting rod 3 are respectively provided with a first connecting plate 34 and a second connecting plate 32. The first connecting plate 34 has a plurality of first connecting holes 36 evenly distributed around its circumference, and the second connecting plate 32 has a plurality of second connecting holes 33 evenly distributed around its circumference. The lever encloses the third connecting plate 4 and the round rod 44 connected to both sides of the third connecting plate 4. The interior of the third connecting plate 4 is provided with a first round hole 41 and a second round hole 42 with increasing inner diameters.

[0042] Furthermore, the end circumference of the mounting shaft 11 is evenly distributed with several ninth connecting holes 12, the second connecting plate 32 is close to the end face of the mounting shaft 11, and the second connecting hole 33 is aligned with the ninth connecting hole 12 and screws are inserted for connection, so as to realize the detachable connection between the connecting rod 3 and the rotating roller 1.

[0043] Furthermore, a fixing rod 31 is extended from one end of the connecting rod 3. The outer diameter of the fixing rod 31 is smaller than that of the connecting rod 3. The end of the fixing rod 31 is connected to the second connecting plate 32. The fixing rod 31 and the second connecting plate 32 extend into the fourth circular hole 22 and are connected to the mounting shaft 11. Through the variable diameter structure, the fixing rod 31 with a smaller diameter is placed in the fourth circular hole 22 with the smallest diameter, achieving a compact design. At the same time, the third circular hole 21 has a larger diameter, which can avoid the position of the mounting shaft 11 and prevent contact with the mounting shaft 11. Meanwhile, the diameter of the fifth circular hole 23 is larger than that of the fourth circular hole 22, which also facilitates the installation of the bearing 9.

[0044] In this invention, the design of the two-support device allows the bearing 9 to be directly supported during grinding, ensuring the stability of the rotating roller 1 during the grinding process. This maximizes the overlap between the roller surface of the rotating roller 1 and the reference, ensuring coaxiality and avoiding or reducing deformation and errors caused by vibration or improper clamping. The roller's circular runout is guaranteed to be within 3 micrometers, significantly improving the grinding accuracy of the roller and ensuring that the geometric shape and dimensional accuracy of the roller surface meet the requirements. It saves time and effort, as the supporting grinding method simplifies the clamping and adjustment process, significantly improving work efficiency. The design of the tail cover 5 provides a stable support base, ensuring accuracy and stability during the grinding process. It has good equipment compatibility, as the supporting grinding method does not require special grinding machine equipment and is applicable to more types of grinding machines, expanding its application range. This method is not only suitable for ironing rollers but also for grinding various types of rollers such as slitting machine rubber rollers, demonstrating wide applicability.

[0045] In this invention, a tailstock and a drive shaft 10 are respectively provided on both sides of the grinding machine. This structure is inherent in existing grinding machines.
