[0008] Furthermore, a planar thrust ball bearing is provided between the driven gear and the circuit board base.

[0009] Furthermore, a bottom cover is connected to the bottom end of the rotating shaft, and the two ends of the rotating shaft are rotatably connected to the base and the top cover respectively through deep groove ball bearings.

[0010] Furthermore, the damping rotation module includes, The lower cover is rotated and is mounted on the upper cover. A damping shaft body is coaxially abutted against a rotating shaft. The damping shaft body is movably connected to a rotating lower cover along its axial direction, and the relative position between the damping shaft body and the rotating lower cover is locked by an adjusting component. A rotating top cover is connected to the damping shaft body; An elastic component is disposed between the rotating upper cover and the rotating lower cover.

[0015] The beneficial effect of this utility model is that the turntable rotation can be remotely controlled via Bluetooth module. Thus, the electric turntable of this invention can meet the needs of users to first make a rough adjustment manually from a distance and then achieve precise positioning of the turntable by jogging via Bluetooth remote control, thereby improving the work efficiency of laser projection operation.

[0016] Furthermore, the device internally uses a flat thrust ball bearing and two deep groove ball bearings to ensure the reliability of the connection between the top cover, base, and rotating shaft; by setting an independent damping rotation module, users can perform manual coarse adjustment through simple operation without affecting the normal operation of other mechanisms, which can ensure the stability of the rotating shaft and maintain the stability of the turntable's jogging accuracy.

[0025] A momentary tracking electric turntable includes a base 1, an upper cover 2, a rotating mechanism 3, and a damped rotation module 4.

[0026] A rotating mechanism 3 is disposed between a base 1 and a top cover 2. The base 1 and the top cover 2 are fixedly connected, forming a mounting cavity for mounting the rotating mechanism 3. The rotating mechanism 3 includes a rotating shaft 31, a bottom cover 34, a driven gear 32, a worm gear 33, a deep groove ball bearing 35, and a flat thrust ball bearing 36. A limiting groove for accommodating the end of the rotating shaft 31 is coaxially provided on the bottom cover 34. The bottom cover 34 is mounted on the bottom end of the rotating shaft 31 by screws. A circuit board base 21 is fixedly connected to the top cover 2. The rotating shaft 31 passes through the circuit board base 21. An annular mounting groove 22 is provided at the top of the circuit board base 21, close to the rotating shaft 31. A main board 23 is installed in the mounting groove 22. An annular groove 24 and a drive groove 25 are provided at the bottom of the circuit board. The annular groove 24 is located outside the mounting groove 22, and the drive groove 25 is located away from the annular groove 24. One side of the mounting groove 22 is connected to the annular groove 24. The worm gear 33 is located in the drive groove 25 and is rotatably connected to the circuit board base 21. The drive groove 25 is equipped with a motor for driving the worm gear 33. The main board 23 is equipped with a controller that can remotely control the motor. In this embodiment, the controller is a Bluetooth module. In other embodiments, the controller can also be set as a WIFI signal transceiver, etc. The driven gear 32 is coaxially sleeved on the rotating shaft 31 and fixedly connected to the rotating shaft 31. The driven gear 32 is located below the circuit board base 21. The driven gear 32 is set as a box shape with the opening facing upward. The meshing part of the driven gear 32 is located in the annular groove 24. The driven gear 32 meshes with the worm gear 33.

[0027] The two ends of the rotating shaft 31 are rotatably connected to the base 1 and the upper cover 2 through deep groove ball bearings 35 respectively. The planar thrust ball bearing 36 is set between the driven gear 32 and the circuit board base 21. The two deep groove ball bearings 35 can ensure the axial accuracy of the rotating shaft system, and the planar thrust ball bearing 36 can ensure the radial accuracy of the rotating body, thus forming a stable and reliable rotating body. The thrust ball bearing serves as the mounting surface for the rotating body, ensuring relatively uniform rotation and preventing skipping (in this embodiment, the thrust ball bearing is of P5 precision, with an inner diameter tolerance ≤-0.008 and a radial runout ≤0.008, ensuring smooth operation); the deep groove ball bearing 35 serves as the fixed mounting mechanism at both ends of the rotating body, ensuring the relative concentricity and straightness accuracy of the rotating body (in this embodiment, the NSK / 6805zz deep groove ball bearing 35 is of P6 precision, with an inner diameter tolerance ≤-0.009 and a radial runout ≤0.015, so theoretically, concentricity and straightness can be controlled within 0.02 by the bearings), thus enabling the overall turntable to achieve a single-cycle inching accuracy of ±20 seconds.

[0028] The damping rotation module 4 is located on the top of the upper cover 2 and is connected to the rotating shaft 31. The damping rotation module 4 includes a rotating upper cover 41, a damping rotation shaft 42, a rotating lower cover 43, and an operating part 44.

[0029] The damping rotation shaft 42 includes a damping shaft body 421, an upper mounting plate 422, a damping shaft isolation pad 423, a damping shaft mounting pad 424, a lower mounting plate 425, elastic washers 426, and an adjusting nut 427. The damping shaft body 421 is coaxially and fixedly connected to the rotating upper cover 41. The upper mounting plate 422, the damping shaft isolation pad 423, the lower mounting plate 425, and the two elastic washers 426 are sequentially fitted onto the damping shaft body 421.

[0030] The damping shaft mounting plate 422 is positioned close to the rotating upper cover 41 and is fixedly connected to the rotating upper cover 41 by screws. The damping shaft mounting plate 425 is fixedly connected to the rotating lower cover 43 by screws. Damping shaft mounting pads 424 are also provided on both sides of the damping shaft mounting plate 425. Two damping shaft elastic washers 426 are positioned back to back, with the front of the damping shaft elastic washers 426 facing the rotating upper cover 41 and the rotating lower cover 43, respectively. The damping shaft adjusting nut 427 is fixedly mounted on the rotating lower cover 43. The damping shaft adjusting nut 427 is threadedly connected to the end of the damping shaft body 421 away from the rotating upper cover 41 to limit the movement of the components sleeved on the damping shaft body 421. The damping size of the damping rotating shaft 42 can be adjusted by adjusting the damping shaft adjusting nut 427 according to actual needs.

[0031] The operating part 44 is set as a slotted 1 / 4 screw. The operating part 44 is fixed at the corresponding position of the rotating upper cover 41. In this embodiment, the rotating upper cover 41 and the damping rotating shaft 42 are connected by an M3*4 cross-slot countersunk screw. The rotating lower cover 43 is connected to the damping rotating shaft 42 by an M3*6 cross-slot pan head screw. When the user turns the rotating upper cover 41 by hand, he can achieve manual rotation without affecting other modules and with a damping effect.

[0032] Furthermore, the base 1 has multiple support legs 11 at its bottom, which are circumferentially arranged on the base 1. The end of each support leg 11 away from the base 1 is inclined away from the axis of the rotating shaft 31. Each support leg 11 has a threaded hole, and an adjusting foot 12 is coaxially threaded onto it. By adjusting the relative distance between the adjusting foot 12 and the support leg 11, the angle between the turntable and the horizontal plane can be adjusted.
