[0037] In the present utility model, unless otherwise specified, the orientation terms such as "upper, lower, top, bottom" generally refer to the directions shown in the drawings or to the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the sake of easy understanding and description, "inner, outer" refer to the inner and outer of the contours of the respective components themselves, but the above orientation terms are not used to limit the present utility model. Embodiment

[0038] See Figures 1 - 4 As shown, a rotating device for a machine tool operation panel mainly includes two major parts, a fixed sleeve 2 and a rotating sleeve 3. The rotating sleeve 3 is carefully arranged inside the fixed sleeve 2, and the cooperation between the two is tight and orderly. Among them, the key oil-free bearing 4 is cleverly arranged between the rotating sleeve 3 and the fixed sleeve 2, enabling the rotating sleeve 3 to rotate along the central axis M.

[0039] The rotating sleeve 3, the fixed sleeve 2 and the oil-free bearing 4 together form a first chamber 9, which is of great significance for the stable operation and performance of the entire device. The fixed sleeve 2 is radially provided with a plunger screw 7 and a locking handle 8, and one ends of the plunger screw 7 and the locking handle 8 are both located inside the first chamber 9. Among them, the locking handle 8 is used to lock or loosen the rotating sleeve 3 so that it can be fixed in position or rotated; by adjusting the position of the plunger screw 7, the rotating sleeve 3 plays a role in position limitation during the rotation process.

[0040] Specifically, the number of the plunger screws 7 is multiple, specifically three in this embodiment. These three plunger screws 7 and the locking handle 8 are circumferentially distributed on the fixed sleeve 2 and are respectively located at the four positions of the front, back, left and right of the fixed sleeve 2. This distribution method has been carefully designed. By reasonably adjusting the position of the plunger screw 7, the rotating sleeve 3 can be effectively kept stable during rotation. When the rotating sleeve 3 rotates, the plunger screw 7 can provide uniform and appropriate support and limitation from different positions, thus avoiding serious shaking of the rotating sleeve 3 during the rotation process.

[0041] Stable rotation can not only ensure the precise control of the machine tool operation panel (abbreviation: operation panel), but also play a key role in protecting the oil-free bearing 4. It avoids excessive wear and impact on the oil-free bearing 4 due to excessive shaking of the rotating sleeve 3, thereby prolonging the service life of the oil-free bearing 4 and reducing the maintenance cost of the equipment.

[0042] In this embodiment, the upper end of the rotating sleeve 3 is detachably connected to the flange 1 by bolts. This connection method has many advantages, which not only facilitates installation and disassembly, but also provides convenience for subsequent maintenance and replacement.

[0043] The operation panel is installed on the above-mentioned flange 1. In order to better protect the flange 1 and ensure the stability and reliability of the installation, an upper gasket 5 is specifically provided at the upper end of the flange 1. The hole positions of the upper gasket 5 correspond precisely to the installation holes of the flange 1.

[0044] The existence of the upper gasket 5 is of great significance. It effectively avoids the direct contact between the flange 1 and the operation panel. During the daily operation of the machine tool, the operation panel is frequently subjected to various forces. Without the isolation of the upper gasket 5, the flange 1 is extremely likely to rub and collide with the operation panel, resulting in the wear of the flange 1. As a buffer and isolation component, the upper gasket 5 greatly reduces the possibility of such wear.

[0045] In this embodiment, there is a special structure at the lower end of the rotating sleeve 3, that is, a radially outward protrusion. At the same time, a corresponding avoidance groove is provided inside the fixed sleeve 2. It should be noted that the protrusion and the fixed sleeve 2 are arranged in a clearance distribution manner.

[0046] The clearance distribution can effectively prevent the protrusion of the rotating sleeve 3 from directly rubbing and colliding with the fixed sleeve 2 during the rotation process. When the rotating sleeve 3 rotates, the protrusion can move freely in the avoidance groove without being blocked by the fixed sleeve 2, thus ensuring the smoothness and stability of the rotation. At the same time, when the rotating sleeve 3 is subjected to forces in different directions and magnitudes, the clearance can provide a certain buffer space, making the interaction between the protrusion and the fixed sleeve 2 more gentle, further extending the service life of the rotating device, and ensuring the reliability and accuracy of the machine tool operation.

[0047] In this embodiment, the lower end of the fixed sleeve 2 presents a unique design, that is, it extends outward to form a circular ring boss. Installation hole positions are provided on the above-mentioned circular ring boss, through which the entire rotating device can be conveniently and firmly installed on the equipment, providing a basic guarantee for its function.

[0048] At the same time, a lower gasket 6 is also provided at the lower end of the fixed sleeve 2. The lower gasket 6 is in close contact with the lower end surface of the circular ring boss, and its hole positions correspond precisely to the installation hole positions on the circular ring boss. On the one hand, the lower gasket 6 buffers the vibration generated by the equipment during the operation of the equipment, effectively reducing the vibration impact on the operation panel above it; on the other hand, the lower gasket 6 and the rotating sleeve 3 are arranged in a clearance distribution, effectively avoiding direct contact and friction between the two during the rotation process, reducing the risk of wear and failure.

[0049] In this embodiment, the oil-free bearing 4 is a sleeve bearing, and this design choice has many significant advantages and considerations. The upper end of the fixed sleeve 2 is specially provided with an overlap surface for placing one end of the oil-free bearing 4 (the part of the oil-free bearing 4 placed on the overlap surface is a flange), and this design provides strong support for the installation and stable operation of the oil-free bearing 4.

[0050] The use of oil-free bearings is of great significance. The metal matrix of oil-free bearings has excellent performance and can withstand large loads. This feature makes it excel in specific working scenarios, especially in heavy loads, low speeds, reciprocating or swinging situations where it is difficult to form an oil film. Under these complex working conditions, ordinary bearings may fail or degrade due to insufficient lubrication, but oil-free bearings can function stably due to their unique structure and material properties.

[0051] In addition, the selection of materials with good wear resistance to make sleeve bearings is also a highlight of this design, including stellite20 cobalt-based alloy, YG8 tungsten-cobalt hard alloy, etc. The sleeve bearing with flange structure further enhances its stability and reliability. This sleeve bearing with high wear resistance can provide good lubrication effect in harsh and difficult to form oil film occasions such as heavy load, low speed, reciprocating or swinging.

[0052] In summary, the embodiments of the utility model achieve the following technical effects: through the application of oil-free bearings, maintenance costs are reduced, work efficiency is improved, and the durability and load capacity of the rotating device are enhanced, so that it can be effectively used in heavy load, low speed, reciprocating or swinging situations; through the combined application of plunger screws and oil-free bearings, the stability and reliability of the rotating device operation are improved, and the service life of the rotating device is extended.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
