Detailed Implementation
[0024] like Figure 1As shown, this embodiment provides a rotary drive device, mainly used for rotating tables to improve space utilization. The rotary drive device includes a fixed base 1, a power drive component 2, a driving gear 3, a driven gear 4, a rotating shaft 5, a rotating seat 6, a limiting pin 7, and a limiting mechanism 8. The fixed base 1 is used to connect to a fixed component, such as a fixed table body 17. The power drive component 2 is mounted on the fixed base 1, and its output end is connected to the driving gear 3. The driven gear 4 meshes with the driving gear 3 and is sleeved on the rotating shaft 5. The rotating shaft 5 is connected to the rotating seat 6, which is used to connect to a rotating component, such as a rotating table body 18. The power drive component 2 drives the driving gear 3 to rotate, which in turn drives the driven gear 4 to rotate. The driven gear 4, rotating shaft 5, and rotating seat 6 rotate together, realizing the rotation function of the rotating component relative to the fixed component.
[0025] The power drive component 2 includes a drive motor, the output shaft of which is connected to the drive gear 3. The drive motor is generally a geared motor. To improve the safety of the rotary drive device, a controller is connected to the drive motor. When the drive motor current exceeds the safe current, the controller stops the drive motor from operating. Since the controller and other electronic components are existing mature technologies, they will not be described in detail.
[0026] like Figure 2 As shown, the limiting pin 7 is mounted on the driving gear 3 or the driven gear 4, and the limiting mechanism 8 is mounted on one side of the limiting pin 7. The limiting mechanism 8 is used to limit the stroke of the limiting pin 7, thereby limiting the rotation angle of the rotating component relative to the fixed base 1. Preferably, the limiting pin 7 is mounted on the driving gear 3. During the rotation of the driving gear 3, the limiting mechanism 8 limits the stroke of the limiting pin 7, thereby limiting the rotation angle of the driving gear 3, and thus limiting the rotation angle of the rotating component relative to the fixed base 1.
[0027] This invention achieves a self-locking function for the rotating component by setting a limiting pin 7 on the driving gear 3 or the driven gear 4, and limiting the rotation angle of the rotating component relative to the fixed component through the action of the limiting mechanism 8 and the limiting pin 7. Its structure is simple and it is safer and more convenient to use.
[0028] In one specific embodiment, the limiting mechanism 8 includes a limiting seat 9 and a limiting adjusting member. The limiting seat 9 is connected to the fixed seat 1 by bolts, and the limiting adjusting member is movably disposed on the limiting seat 9. The limiting adjusting member is used to limit the stroke of the limiting pin 7. By adjusting the position of the limiting adjusting member, the stroke range of the limiting pin 7 can be controlled.
[0029] like Figure 2As shown, specifically, the limiting adjustment component includes a limiting adjustment bolt 10 and a limiting plate 11. The limiting plate 11 is fixed on the limiting seat 9 and has a threaded hole. The limiting adjustment bolt 10 is threadedly connected to the threaded hole, and its end has a blocking part for blocking the limiting pin 7. Rotating the limiting adjustment bolt 10 causes the blocking part at one end of the limiting adjustment bolt 10 to move forward or backward, controlling the travel range of the limiting pin 7.
[0030] Preferably, the limiting seat 9 is provided with a track groove 13 adapted to the limiting pin 7. The limiting adjusting bolt 10 is provided with a locking nut 12, which is in close contact with the surface of the limiting plate 11 to improve the stability of the limiting adjusting bolt 10.
[0031] like Figure 1 As shown, in one specific embodiment, the fixed base 1 is provided with a support panel 14, and a bearing 15 is provided between the support panel 14 and the rotating shaft 5. The support panel 14 has a first mounting hole, and the first mounting hole is equipped with a first mounting screw for connecting the fixed component. A thrust bearing 16 is provided between the rotating base 6 and the fixed component to make the rotation of the rotating base 6 and the rotating component more stable.
[0032] The fixing base 1 includes a bent plate with a flanged edge. A second mounting hole is provided on the flange, and a second mounting screw for connecting the fixing component is fitted into the second mounting hole. The flanged edge of the plate and the support panel 14 support the fixing component, thereby improving the stability of the fixing component.
[0033] like Figure 3 As shown, this embodiment also provides a rotating table, including the above-mentioned rotating drive device, and further including a fixed table body 17 and a rotating table body 18. The fixed table body 17 is connected to the fixed base 1 as a fixing component, and the rotating table body 18 is connected to the rotating base 6 as a rotating component. The rotating base 6 is provided with screws for fixing the rotating table body 18.
[0034] like Figure 4 As shown, specifically, the rotating table 18 includes a rotating tabletop 19, a rotating support base 20, and rollers 21. One end of the rotating tabletop 19 is connected to the rotating base 6, and the other end of the rotating tabletop 19 extends to the outside of the fixed table body 17 and connects to the rotating support base 20. The rollers 21 are located at the bottom of the rotating support base 20. The rotation arm of the rotating tabletop 19 can be within a range of 3 meters to meet different usage needs. The rotating table of this utility model occupies less space when closed and increases usable space when open. The rotation angle of the rotating table body 18 relative to the fixed table body 17 is limited by the limiting mechanism 8, making it safer to use.
[0035] Compared with the prior art, the present invention has the following advantages:
[0036] 1. The structure is simple and versatile. The length of the rotating table 19 can be selectively set according to different usage scenarios, thereby adjusting the length of the rotation lever arm.
[0037] 2. Depending on the usage scenario, the position of the limit adjustment bolt 10 can be selectively set to adjust the rotation angle of the rotating table body 18, thereby improving the safety of use.
[0038] 3. Depending on the usage scenario, selectively set the size and thickness of the driving gear 3 and the driven gear 4 to change the rotation angle of the rotating table body 18.
[0039] 4. The installation direction and position of the drive motor are highly flexible, and the overall installation of the rotating table is simple, quick, and convenient.
[0040] 5. The rotary drive device occupies little space on the rotating table, is lightweight, has a high load-bearing capacity, and the rotating table body 18 rotates smoothly.

They can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model. Furthermore, the specific features and structures described in the embodiments are included in at least one implementation method. Those skilled in the art can combine features from different implementation methods without contradiction. The scope of protection of this utility model is not limited to the specific implementation methods described above. Based on the basic technical concept of this utility model, implementation methods that can be conceived by those skilled in the art without creative effort are all within the scope of protection of this utility model.
