[0018] The machine tool for machining shafts provided in this disclosure can achieve the following technical effects:

[0019] This disclosure provides a machine tool for machining shaft components, comprising a top-shaped plate, a first bottom-shaped plate, a rotating shaft, a first rotating cylinder, a motor, a second bottom-shaped plate, a hydraulic cylinder, a pressure plate, and a second rotating cylinder. The first bottom-shaped plate is mounted on the horizontal wall of the top-shaped plate, supporting the motor and the rotatable rotating shaft. The rotating shaft is rotatably mounted on the top wall of the first bottom-shaped plate along the height direction of the top-shaped plate, and can rotate relative to the top wall of the first bottom-shaped plate. The first rotating cylinder is mounted on the top of the rotating shaft and is coaxial with the rotating shaft, rotating under the drive of the rotating shaft to support and hold the hollow shaft. The motor is mounted on the inner side of the first bottom-shaped plate, and the rotating end of the motor is connected to the bottom end of the rotating shaft via a coupling. The second bottom-shaped plate is mounted on the horizontal wall of the top-shaped plate and located to the side of the first bottom-shaped plate, supporting the hydraulic cylinder. A hydraulic cylinder is installed on the top wall of the second U-shaped plate along the height direction of the U-shaped plate, with its tail end facing the horizontal wall of the U-shaped plate. It provides driving force to achieve the lifting function. A pressure plate is installed on the moving end of the hydraulic cylinder and moves up and down under its drive. A second rotating drum is rotatably installed on the pressure plate and coaxially distributed with the first rotating drum, used to press against the hollow shaft placed on the first rotating drum. Under the drive of the hydraulic cylinder, the second rotating drum can abut against the first rotating drum.

[0020] In use, after placing the hollow shaft on the first rotating drum, the hydraulic cylinder is activated, causing the pressure plate to move until the second rotating drum presses the hollow shaft against the first rotating drum. Then, the motor is activated, causing the shaft to rotate, which in turn rotates the first rotating drum. Because the second rotating drum can rotate relative to the pressure plate, under the action of friction, the second rotating drum and the pressed hollow shaft will rotate along with the first rotating drum. Furthermore, during the rotation of the hollow shaft, only the coaxially distributed first and second rotating drums rotate, while the first and second C-shaped plates remain stationary. Therefore, interference can be avoided, and the grinding work of the entire inner and outer rings of the hollow shaft can be completed.

[0038] Combination Figures 1 to 5 As shown, this embodiment of the present disclosure provides a machine tool for machining shaft components, including a U-shaped plate 1, a first C-shaped plate 2, a rotating shaft 3, a first rotating cylinder 4, a motor 5, a second C-shaped plate 6, a hydraulic cylinder 7, a pressure plate 8, and a second rotating cylinder 9. The first C-shaped plate 2 is mounted on the horizontal wall of the U-shaped plate 1 to support and mount the motor 5 and the rotatable rotating shaft 3. The rotating shaft 3 is rotatably mounted on the top wall of the first C-shaped plate 2 along the height direction of the U-shaped plate 1, and can rotate relative to the top wall of the first C-shaped plate 2. The first rotating cylinder 4 is mounted on the top of the rotating shaft 3 and is coaxially distributed with the rotating shaft 3, rotating under the drive of the rotating shaft 3, and is used to support and hold hollow shafts. The motor 5 is mounted on the inner side of the first C-shaped plate 2, and the rotating end of the motor 5 is connected to the bottom end of the rotating shaft 3 via a coupling. The second C-shaped plate 6 is installed on the horizontal wall of the first C-shaped plate 1 and located to the side of the first C-shaped plate 2, serving to support the installation of the hydraulic cylinder 7. The hydraulic cylinder 7 is installed on the top wall of the second C-shaped plate 6 along the height direction of the first C-shaped plate 1, with its tail end facing the horizontal wall of the first C-shaped plate 1, providing driving force to achieve the lifting function. The pressure plate 8 is installed on the moving end of the hydraulic cylinder 7 and moves up and down under the drive of the hydraulic cylinder 7. The second rotating cylinder 9 is rotatably installed on the pressure plate 8 and is coaxially distributed with the first rotating cylinder 4, serving to press against the hollow shaft placed in the first rotating cylinder 4. Under the drive of the hydraulic cylinder 7, the second rotating cylinder 9 can abut against the first rotating cylinder 4.

[0039] This embodiment of the machine tool for machining shafts provides a method for grinding hollow shafts. After placing a hollow shaft on a first rotating drum 4, the hydraulic cylinder 7 is activated, causing the pressure plate 8 to move until a second rotating drum 5 presses the hollow shaft against the first rotating drum 4. Then, the motor 5 is activated, causing the rotating shaft 3 to rotate, which in turn rotates the first rotating drum 4. Since the second rotating drum 9 can rotate relative to the pressure plate 8, under the action of friction, the second rotating drum 9 and the pressed hollow shaft will rotate along with the first rotating drum 4. Furthermore, during the rotation of the hollow shaft, only the coaxially distributed first rotating drum 4 and second rotating drum 9 rotate, while the first C-shaped plate 2 and second C-shaped plate 6 remain stationary. Therefore, interference can be avoided, and the grinding work on the entire inner and outer rings of the hollow shaft can be completed.

[0040] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the assembly also includes a first electric push rod 10, a first transverse sliding plate 11, a first linear slide 12, a first vertical sliding plate 13, a first drive motor 14, and a first grinding wheel 15. The first electric push rod 10 is installed along the length of the U-shaped plate 1 on the vertical wall of the U-shaped plate 1, with its moving end facing the first U-shaped plate 2, providing driving force to achieve transverse movement. The first transverse sliding plate 11 is installed at the moving end of the first electric push rod 10 and moves laterally under the drive of the first electric push rod 10. The first linear slide 12 is installed along the height of the U-shaped plate 1 on the first transverse sliding plate 11, providing driving force to achieve vertical movement. The first vertical sliding plate 13 is installed at the moving end of the first linear slide 12 and moves vertically under the drive of the first linear slide 12. The first drive motor 14 is mounted on the first vertical moving plate 13 along the height direction of the top plate 1, with the tail end of the first drive motor 14 facing the horizontal wall of the top plate 1, to provide driving force to achieve the rotational motion function. The first grinding wheel 15 is mounted on the rotating end of the first drive motor 14 and rotates under the drive of the first drive motor 14.

[0041] In this embodiment, controlling the first electric push rod 10 to operate causes the first transverse plate 11 to move laterally, ultimately causing the first grinding wheel 15 to move laterally. Controlling the first linear slide 12 to operate causes the first vertical plate 13 to move vertically, ultimately causing the first grinding wheel 15 to move vertically. Controlling the first drive motor 14 to operate causes the first grinding wheel 15 to rotate. Therefore, driven by the first electric push rod 10 and the first linear slide 12, the first grinding wheel 15 can move to the side of the hollow shaft and then abut against the outer ring of the hollow shaft. Driven by the first drive motor 14, the first grinding wheel 15 can grind the outer ring of the hollow shaft, ultimately completing the grinding work of the entire outer ring of the hollow shaft.

[0042] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first optical axis 16. The first optical axis 16 is slidably disposed along the length direction of the L-shaped plate 1 through the vertical wall of the L-shaped plate 1 and is connected to the first transverse plate 11.

[0043] In this embodiment of the disclosure, the first optical axis 16 serves as a guide and support to improve the stability of the first transverse plate 11 when it moves laterally and to reduce the radial force on the moving end of the first electric push rod 10.

[0044] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first support 17. The first support 17 is fitted onto the first drive motor 14 and mounted on the first vertical moving plate 13.

[0045] In this embodiment, the first support 17 is used to enable detachable mounting of the first drive motor 14 and the first vertical moving plate 13. This facilitates mounting the first drive motor 14 onto the first vertical moving plate 13 or facilitating detachment of the first drive motor 14 from the first vertical moving plate 13.

[0046] Optionally, combined Figure 1 and Figure 4 As shown, the system also includes a second electric push rod 18, a second transverse plate 19, a second linear slide 20, a second vertical slide 21, a second drive motor 22, and a second grinding wheel 23. The second electric push rod 18 is installed along the length of the T-shaped plate 1 on the vertical wall of the T-shaped plate 1. The moving end of the second electric push rod 18 faces the same direction as the moving end of the first electric push rod 10, providing driving force to achieve transverse movement. The second transverse plate 19 is installed on the moving end of the second electric push rod 18 and moves laterally under the drive of the second electric push rod 18. The second linear slide 20 is installed along the height of the T-shaped plate 1 on the second transverse plate 19, providing driving force to achieve vertical movement. The second vertical slide 21 is installed on the moving end of the second linear slide 20 and moves vertically under the drive of the second linear slide 20. The second drive motor 22 is mounted on the second vertical moving plate 21 along the height direction of the L-shaped plate 1. The rotating end of the second drive motor 22 faces the horizontal wall of the L-shaped plate 1 and is used to provide driving force to achieve the rotational motion function. The second grinding wheel 23 is mounted on the rotating end of the second drive motor 22 and rotates under the drive of the second drive motor 22. The diameter of the second grinding wheel 23 is smaller than that of the first grinding wheel 15 so as to facilitate insertion into the interior of the second rotating cylinder 9, the hollow shaft, and the first rotating cylinder 4.

[0047] In this embodiment, controlling the second electric push rod 18 to operate causes the second transverse plate 19 to move laterally, ultimately causing the second grinding wheel 23 to move laterally. Controlling the second linear slide 20 to operate causes the second vertical plate 21 to move vertically, ultimately causing the second grinding wheel 23 to move vertically. Controlling the second drive motor 22 to operate causes the second grinding wheel 23 to rotate. Therefore, driven by the second electric push rod 18 and the second linear slide 20, the second grinding wheel 23 can move into the interior of the second rotating cylinder 9, the hollow shaft, and the first rotating cylinder 4, and then abut against the inner ring of the hollow shaft. Driven by the second drive motor 22, the second grinding wheel 23 can grind the inner ring of the hollow shaft, ultimately completing the grinding work of the entire inner ring of the hollow shaft.

[0048] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a second optical axis 24. The second optical axis 24 is slidably disposed along the length direction of the L-shaped plate 1 through the vertical wall of the L-shaped plate 1 and is connected to the second transverse plate 19.

[0049] In this embodiment, the second optical axis 24 serves as a guide and support to improve the stability of the second transverse plate 19 during lateral movement and reduce the radial force on the moving end of the second electric push rod 18.

[0050] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a second support 25. The second support 25 is fitted onto the second drive motor 22 and mounted on the second vertical moving plate 21.

[0051] In this embodiment, the second support 25 is used to enable detachable mounting of the second drive motor 22 and the second vertical moving plate 21. This facilitates mounting the second drive motor 22 onto the second vertical moving plate 21, or facilitating the removal of the second drive motor 22 from the second vertical moving plate 21.

[0052] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a bearing housing 26 and a hollow angular contact ball shaft. The bearing housing 26 is mounted on the top wall of the first U-shaped plate 2 and sleeved on the rotating shaft 3. The hollow angular contact ball shaft is mounted opposite to the bearing housing 26 and the rotating shaft 3.

[0053] In this embodiment, the bearing housing 26 is used to support and mount the hollow angular contact ball shaft, and to limit the movement of the hollow angular contact ball shaft. The oppositely mounted hollow angular contact ball shaft is used to support and mount the rotatable shaft 3, reducing the frictional force on the shaft 3 and improving the rotational accuracy of the shaft 3.

[0054] Optionally, combined Figures 1 to 3 As shown, it also includes a thrust ball bearing 27. The thrust ball bearing 27 is installed between the pressure plate 8 and the second rotating cylinder 9.

[0055] In this embodiment of the disclosure, the thrust ball bearing 27 is used to realize the rotatable installation between the second rotating cylinder 9 and the pressure plate 8, and to reduce the friction between the second rotating cylinder 9 and the pressure plate 8.

[0056] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a third optical axis 28. The third optical axis 28 is slidably disposed along the height direction of the upper plate 1 through the top wall of the second shaped plate 6 and is connected to the pressure plate 8.

[0057] In this embodiment, the third optical axis 28 serves as a guide and support, improving the stability of the pressure plate 8 during lifting and lowering movements, and reducing the radial force on the moving end of the hydraulic cylinder 7.
