[0027] Please refer to Figure 1-6, a dual-axis electric non-magnetic turntable, comprising a mechanical chassis 1, a drive connection mechanism 8, and a dual-mode drive mechanism 9. The dual-mode drive mechanism 9 includes a drive box 901, a turbine 902, a worm 903, a first gear rod 904, a second gear rod 905, a first bevel gear 906, a second bevel gear 907, a connection sleeve 908, a limit pin 909, a drive shaft 910, a drive motor 911, a stabilizing partition 912, and a manual rotating wheel 913. Inside the drive box 901, a meshing turbine 902 and worm 903 are rotatably connected. A first gear rod 904 is fixedly installed on the outside of the worm 903. A second gear rod 905 meshes with the top of the first gear rod 904. A first bevel gear 906 is fixedly installed on the outside of the second gear rod 905. A second bevel gear 907 meshes with the bottom of the first bevel gear 906. A connection sleeve 908 is fixedly installed at the bottom of the second bevel gear 907. A limit pin 909 is inserted into the inside of the connection sleeve 908. A drive shaft 910 is inserted into the bottom of the connection sleeve 908. The bottom of the drive shaft 910 is connected to a drive motor 911. A stabilizing partition 912 is fixedly installed inside the drive box 901.

[0028] The mechanical chassis 1 includes a bottom plate 101, threaded rods 102, threaded limit rings 103, threaded sleeves 104, connection rings 105, hinge members 106, and a top plate 107. Three threaded rods 102 are fixedly installed on the top of the bottom plate 101. A threaded limit ring 103 and a threaded sleeve 104 are threadedly connected to the outside of each threaded rod 102. A connection ring 105 is rotatably connected to the top of each threaded sleeve 104. A hinge member 106 is installed on the top of each connection ring 105. The top of the hinge member 106 is connected to a top plate 107.

[0029] The drive connection mechanism 8 includes a first connection block 801, a second connection block 802, a connection clamping plate 803, and a threaded fixing rod 804. A first connection block 801 is fixedly installed on the right side of one of the all-ceramic mechanical bearings 3. A second connection block 802 is clamped to the right side of the first connection block 801. A connection clamping plate 803 is clamped to the top of the first connection block 801 and the second connection block 802. A threaded fixing rod 804 is rotatably connected to the inside of the connection clamping plate 803.

[0030] Embodiment 1:

[0031] This embodiment details the switching between the electric and manual drive modes of the dual-mode drive mechanism 9 and the specific drive operations.

[0032] When the dual-mode drive mechanism 9 is installed, first, the turbine 902 is rotatably connected between the inner left wall and the inner right wall of the drive box 901 through bearings, and the worm 903 is rotatably connected between the inner front wall and the inner rear wall of the drive box 901 through bearings. Moreover, the worm 903 penetrates through the stable partition 912 and is rotatably connected thereto, ensuring that the meshing clearance between the turbine 902 and the worm 903 is uniform.

[0033] In the electric drive mode, start the drive motor 911. Its output shaft is connected to the bottom of the transmission shaft 910 through a coupling. The top of the transmission shaft 910 is inserted into the connecting sleeve 908, and circumferential fixation is achieved by the limit pin 909 passing through the back of the connecting sleeve 908, the transmission shaft 910, and the front of the connecting sleeve 908. When the transmission shaft 910 rotates, it drives the second bevel gear 907 to rotate, which meshes with the first bevel gear 906, driving the second gear rod 905 to rotate. Furthermore, the worm 903 is driven to rotate through the first gear rod 904, and the worm 903 drives the turbine 902 to realize the electric rotation of the turntable. During this process, the stable partition 912 forms a support for the middle part of the worm 903, reducing transmission vibration.

[0034] When it is necessary to switch to the manual drive mode, first remove the threaded fixing rod 804 of the drive connection mechanism 8. The second connection block 802 on the left side of the manual rotating wheel 913 is clamped into the card slot of the first connection block 801, aligning the rotating shaft of the manual rotating wheel 913 with the central axis of the first connection block 801. Then, the top of the first connection block 801 and the second connection block 802 are clamped by the connection card plate 803, and the threaded fixing rod 804 is screwed in for fixation. At this time, rotate the manual rotating wheel 913. Through the second connection block 802, it is transmitted to the inner ring shaft 5 through the first connection block 801, the all-ceramic mechanical bearing 3, and the connecting shaft 4, realizing manual fine adjustment and operating without electricity.

[0035] Embodiment 2:

[0036] In this embodiment, the leveling structure and operation steps of the mechanical chassis 1 are described in detail.

[0037] During the leveling operation, first place the level on the upper surface of the top plate 107 and observe the direction of the bubble offset. If the left side of the top plate 107 is high and the right side is low, rotate the threaded sleeve 104 on the left threaded rod 102 clockwise to move it downward along the threaded rod 102. At the same time, rotate the threaded sleeves 104 on the two right threaded rods 102 counterclockwise to move them upward, and adjust the inclination angle of the top plate 107 through the connecting ring 105 and the hinge 106.

[0038] If the front of the top plate 107 is high and the rear is low, adjust the threaded sleeve 104 of the front row of threaded rods 102 downward and the threaded sleeve 104 of the rear row of threaded rods 102 upward.

[0039] During the adjustment process, the position of the level needs to be moved multiple times to ensure that the overall flatness of the top plate 107 meets the standard.

[0040] After the leveling is completed, tighten the threaded limit ring 103 so that it abuts against the bottom of the threaded sleeve 104 to prevent the threaded sleeve 104 from loosening.

[0041] This leveling process does not require the aid of an electric system or external complex tools. By manually rotating the three threaded sleeves 104, the horizontal adjustment of the top plate 107 can be quickly achieved based on the three-point support principle, which is suitable for space-limited environments such as the wild.

[0042] Embodiment 3:

[0043] This embodiment details the assembly and connection operations of the load mounting table 6, inner ring shaft 5, all-ceramic mechanical bearing 3, and drive connection mechanism 8.

[0044] During assembly, first fix the U-shaped bracket 2 to the top of the top plate 107. The all-ceramic mechanical bearings 3 are respectively installed on the left and right sides of the U-shaped bracket 2. The inner ring of the bearing is in interference fit with the connecting shaft 4, and both ends of the connecting shaft 4 are fixed to the U-shaped bracket 2 through bearing seats.

[0045] The inner ring shaft 5 passes through the central holes of the two connecting shafts 4 and is circumferentially fixed by key connection. The load mounting table 6 is welded to the top of the inner ring shaft 5, and a balance weight 7 is installed at the bottom through bolts. The weight of the balance weight 7 is selected according to the position of the load center of gravity to ensure that the inner ring shaft 5 remains balanced in the pitching direction.

[0046] When installing the drive connection mechanism 8, fix the first connection block 801 to the right side of the right all-ceramic mechanical bearing 3 through bolts. The second connection block 802 is snapped into the slot of the first connection block 801 so that the central hole of the second connection block 802 is aligned with the axis of the connecting shaft 4. Then, snap the connection card plate 803 into the slots at the tops of the first connection block 801 and the second connection block 802. The threaded fixing rod 804 is screwed into the threaded hole at the top of the connection card plate 803, sequentially passes through the connection card plate 803, the first connection block 801, and the second connection block 802, and is locked by the nut at the bottom to achieve the rigid connection of the drive connection mechanism 8 to the shafting.

[0047] When the turbine 902 of the dual-mode drive mechanism 9 rotates, it drives the first connection block 801 through the second connection block 802 on the left, and then drives the connecting shaft 4 and the inner ring shaft 5 to rotate, realizing the azimuth angle adjustment of the load mounting table 6;

[0048] When manually driving, precise angle adjustment is achieved through the manual rotating wheel 913 along the above transmission path. The all-ceramic mechanical bearing 3 ensures low friction and high precision when the shafting rotates.

[0049] In summary, for this dual-axis electric non-magnetic turntable, the drive mode is switched through the dual-mode drive mechanism 9. When the drive motor 911 starts, it drives the transmission shaft 910 to rotate. After the second bevel gear 907 meshes with the first bevel gear 906, it drives the second gear rod 905 to rotate. Then, through the first gear rod 904, it drives the worm 903 to mesh with the turbine 902, realizing the electric drive of the turntable. When manual operation is required, pull out the threaded fixing rod 804. The manual rotating wheel 913 is clamped to the first connecting block 801 through the second connecting block 802 on the left and fixed again through the threaded fixing rod 804, realizing the manual drive of the turntable. It can be finely adjusted without electricity, meeting the needs of power failure or precise control.

[0050] Moreover, for this dual-axis electric non-magnetic turntable, with the leveling design of the mechanical chassis 1, three threaded rods 102 on the bottom plate 101 are respectively sleeved with threaded sleeves 104. Rotating the threaded sleeves 104 can adjust the height of the connecting ring 105. The connecting ring 105 is connected to the top plate 107 through the hinge 106. By synchronously or separately rotating the three threaded sleeves 104, the level of the top plate 107 is adjusted based on the three-point support principle. Without a complex electric system or external tools, leveling can be quickly completed manually in restricted environments such as the wild, simplifying the operation and reducing costs, and solving the problems existing in the operation flexibility and adaptability of the existing dual-axis non-magnetic turntable.
