[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0044] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the sake of easy understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms are not used to limit the present utility model. Embodiment

[0045] See Figures 1-5 As shown, a rotating device for a machine tool operation panel, this rotating device is composed of multiple key components working together to achieve efficient, stable and flexible rotation functions.

[0046] First of all, there is a fixed sleeve 1 in the device, which serves as the basic structure and has an inner rotating sleeve 2 carefully arranged inside. A first annular groove is formed by enclosing them skillfully. Inside this first annular groove, ball bearings 3 are placed. These ball bearings 3 play a crucial role. They effectively reduce the friction when the inner rotating sleeve 2 rotates relative to the fixed sleeve 1, making the rotation process smoother and more fluent, and improving the operation accuracy and efficiency.

[0047] Above the fixed sleeve 1, there is another outer rotating sleeve 4 that cooperates with it. The upper end of the fixed sleeve 1 and the lower end of the outer rotating sleeve 4 are accurately enclosed to form a second annular groove. Inside this second annular groove, ball bearings 5 are also equipped. These ball bearings 5 further optimize the performance when the outer rotating sleeve 4 rotates relative to the fixed sleeve 1, ensuring the smoothness and reliability of the rotation.

[0048] The above-mentioned inner rotating sleeve 2 and outer rotating sleeve 4 are locked and connected by screws, so that the inner rotating sleeve 2 and the outer rotating sleeve 4 can rotate relative to the fixed sleeve 1 along the central axis M as a whole.

[0049] Due to the application of the ball bearings 3, the friction can be effectively reduced, the rotation efficiency can be improved, and the heat problem generated during the high-speed rotation of the rotating device can be solved, thereby improving the stability and service life of the rotating device.

[0050] Furthermore, the upper end of the outer rotating sleeve 4 has a radially outward circular ring boss, and mounting holes are provided at the circular ring boss for the installation of the machine tool operation panel. The lower end of the fixed sleeve 1 has a radially outward circular ring boss, and mounting holes are provided at the circular ring boss for fixing the rotating device on the equipment.

[0051] To meet different usage requirements and operating scenarios, a locking handle 6 and a damping adjustment component 7 are also radially provided on the fixed sleeve 1. Both the locking handle 6 and the damping adjustment component 7 can rotate flexibly and can tightly abut against the outer surface of the inner rotating sleeve 2. When it is necessary to fix the position of the rotating device, just rotate the locking handle 6 so that it tightly abuts against the inner rotating sleeve 2, thereby preventing the rotating action. The damping adjustment component 7 can adjust the resistance during rotation according to actual needs. For example, in the case of fine operation and slow rotation speed requirements, the damping can be increased to make the rotation more stable and controllable; while when it is necessary to quickly rotate the operation panel, the damping can be appropriately reduced.

[0052] In this embodiment, a limit groove 21 is carefully provided at the lower end of the inner rotating sleeve 2, and the fixed sleeve 1 is equipped with a position-adjustable limit screw 8. One end of the limit screw 8 can accurately abut into the limit groove 21, thereby effectively limiting the rotation angle.

[0053] It is worth further explaining that not only one limit groove is provided at the lower end of the inner rotating sleeve 2, but rather two limit grooves, one long and one short, are ingeniously provided. This design brings more flexibility and controllability to the use of the rotating device.

[0054] During the actual operation process, as the inner rotating sleeve 2 rotates, both of these limit grooves can rotate to the position of the limit screw. When the shorter limit groove rotates to contact the limit screw, it will limit the rotation of the inner rotating sleeve 2 within a specific angle range, which is suitable for some operation scenarios that require a smaller rotation amplitude. When the longer limit groove rotates to contact the limit screw, the inner rotating sleeve 2 is allowed to rotate within a larger angle range, meeting the operation requirements with greater demands for the rotation angle. This diverse limit design greatly improves the adaptability and practicality of the rotating device of the machine tool operation panel, providing a strong guarantee for the efficient and precise operation of the machine tool.

[0055] In this device, the locking handle 6 and multiple damping adjustment components 7 are evenly distributed on the fixed sleeve 1 in a circumferential manner. Among them, the number of the damping adjustment components 7 is specifically set to three, and the three damping adjustment components 7 and the locking handle 6 are respectively located in the four directions of the front, back, left, and right of the fixed sleeve 1. The three damping adjustment components 7 are distributed at different positions and can uniformly and stably adjust the damping of rotation from multiple directions. This circumferential distribution design greatly improves the convenience and flexibility of operation, making the rotation control of the machine tool operation panel more accurate and efficient.

[0056] Correspondingly, a first groove 22 in a ring structure is provided on the inner rotating sleeve 2, and one ends of the locking handle 6 and the damping adjustment assembly 7 are exactly located in the first groove 22. Such a design not only makes the overall structure more compact and beautiful, but also makes full use of the space and avoids mutual interference between components.

[0057] In this embodiment, the damping adjustment assembly 7 is jointly composed of a copper column 71, a disc spring 72 and a setscrew 73, and its structural design is delicate and the function is clear. A radial hole is specially provided on the fixed sleeve 1, and the inside of the radial hole has an internal thread threadedly connected to the setscrew 73.

[0058] The copper column 71, the disc spring 72 and the setscrew 73 are properly arranged in the radial hole in sequence from the inside to the outside. When the damping of rotation needs to be adjusted, by rotating the setscrew 73, it moves along the thread in the radial hole. As the setscrew 73 moves, different degrees of pressure are exerted on the disc spring 72. With the change of the pressure received by the disc spring 72, the thrust on the copper column 71 is correspondingly changed.

[0059] The copper column 71 is located in the first groove 22, and the change of the thrust it receives will directly affect the rotation resistance of the inner rotating sleeve 2. For example, when the setscrew 73 is screwed inwards, the pressure on the disc spring 72 increases, and the disc spring 72 pushes the copper column 71 to contact the inner wall of the first groove 22 more tightly, thereby increasing the damping when the inner rotating sleeve 2 rotates, slowing down the rotation speed and making the rotation action more stable and controllable. On the contrary, when the setscrew 73 is screwed outwards, the thrust of the disc spring 72 on the copper column 71 decreases, and the resistance received by the inner rotating sleeve 2 during rotation is reduced, and the rotation speed increases accordingly.

[0060] This design of precisely adjusting the rotation damping through the damping adjustment assembly 7 provides great flexibility and accuracy for the rotation control of the machine tool operation panel, and can meet the operation requirements under various different working conditions.

[0061] In this embodiment, the screws for locking the outer rotating sleeve 4 and the inner rotating sleeve 2 are not ordinary single screws, but are jointly composed of a first anti-disassembly screw 91 and a second anti-disassembly screw 92. This unique screw combination design provides double guarantee for the connection stability between the two.

[0062] Specifically, the first anti-disassembly screw 91 locks the outer rotating sleeve 4 and the inner rotating sleeve 2 from the outside to the inside. Its acting direction is to penetrate from the outside to the inside, so that the outer rotating sleeve 4 and the inner rotating sleeve 2 are tightly combined in this direction and are not easy to loosen.

[0063] At the same time, the second anti-disassembly screw 92 locks the inner rotating sleeve 2 and the outer rotating sleeve 4 from the inside to the outside. Its acting direction is opposite to that of the first anti-disassembly screw 91, penetrating from the inside to the outside, and further enhancing the firmness of the connection between the two.

[0064] Through the locking of these two sets of screws in different directions, a firm and reliable fixed connection can be ensured in all directions between the outer rotating sleeve 4 and the inner rotating sleeve 2. This design effectively avoids the loosening of the connection between the two due to frequent rotation movements or external vibrations during the operation of the machine tool.

[0065] In this embodiment, the lower end of the outer side of the outer rotating sleeve 4 has a unique downward annular protrusion 41. At the same time, the upper end of the fixed sleeve 1 correspondingly has a sunken step 11 for placing the annular protrusion 41.

[0066] This ingenious design has an important function. The annular protrusion 41 and the sunken step 11 cooperate with each other to form an effective protective barrier. In the actual working environment of the machine tool, there are often a large amount of dust and various fine impurities. And this protective design can greatly avoid the direct entry of external dust and other impurities into the second annular groove.

[0067] Without this protective measure, after dust and other impurities enter the second annular groove, they may affect the normal operation of the ball bearings 5, increase the resistance of rotation, and reduce the accuracy and smoothness of rotation. However, with the cooperation of the annular protrusion 41 and the sunken step 11, the intrusion of impurities is effectively blocked, ensuring the cleanliness inside the second annular groove and the good working environment of the ball bearings 5.

[0068] In summary, the rotating device provided by the present utility model is not only firm and reliable, but also can effectively transmit the rotational force, ensuring the integrity and stability of the entire rotating device during the working process, including:

[0069] 1. Using ball bearings as transmission components, which have the advantages of low friction, high precision, high stability, etc., can effectively reduce the heat generated during the high-speed rotation of the rotating device, thereby reducing the temperature of the rotating device and improving its stability and service life.

[0070] 2. The application of the damping adjustment component and the screws can be locked at any position, which can effectively prevent the rotating device from shifting or falling off during high-speed rotation, ensuring the stability of the rotating device.

[0071] 3. The distribution among the inner rotating sleeve, the outer rotating sleeve, and the fixed sleeve is reasonable, and the load distribution on the outer rotating sleeve is more uniform, avoiding excessive stress on some components, thereby improving the durability and reliability of the rotating device, enabling it to maintain stable performance during high-intensity and long-term use, and thus improving the operation efficiency and accuracy of the machine tool.

[0072] 4. Compared with the prior art, this technical solution can better solve the problems in the design and assembly of the rotating device, such as complex structure, difficult assembly, etc., thereby reducing production costs and improving production efficiency.
