[0021] A ball turntable device provided by an embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

[0022] Figure 1 A three-dimensional structural diagram of a ball turntable device provided in an embodiment of the utility model is shown; Figure 2 A partial exploded structural diagram of a ball turntable device provided in an embodiment of the utility model is shown; Figure 3 The front view of the ball turntable device provided by the embodiment of the utility model is shown; Figure 4 Shows Figure 3 Partial enlarged view of part A in the middle; Figure 5 A top view of a ball turntable device provided in an embodiment of the utility model is shown; Figure 6 A three-dimensional structural diagram of a bracket provided by an embodiment of the utility model is shown; Figure 7 The figure shows a three-dimensional structure diagram of the rotating shaft assembly provided by the embodiment of the utility model. Figure 1 to Figure 7 As shown, a ball turntable device provided by an embodiment of the utility model is suitable for realizing position switching and circular motion of various fixtures in a production line, and is suitable for user needs that do not require high rotation accuracy and speed. A ball turntable device provided by an embodiment of the utility model includes: a bracket 1, a rotating platform 2, a turntable assembly 3, and a shaft assembly 4, wherein the rotating platform 2, the turntable assembly 3, and the bracket 1 are arranged in sequence from top to bottom and are connected through the shaft assembly 4 to realize the rotation of the rotating platform 2 on the turntable assembly 3; specifically, the turntable assembly 3 is in the shape of a disk and is evenly provided with a plurality of first openings 31 along its outer diameter edge, Figure 2A structural form in which the first opening 31 is circular is shown, wherein the number of the first openings 31 can be adjusted according to user needs, and a plurality of first openings 31 form a circumference on the turntable assembly 3. Of course, if the rotating platform 2 needs to bear a larger supporting force, a plurality of circles of first openings 31 can also be set, wherein balls 33 are arranged in the first openings 31, and the number of balls 33 should be equal to or less than the number of first openings 31, but the balls 33 should be evenly distributed on the turntable assembly 3 so as to be evenly stressed. The diameter of the balls 33 is smaller than the diameter of the first openings 31 to ensure the rolling of the balls 33 in the first openings 31, and the position constraint of the balls 33 is synchronously realized by using the first openings 31, and the number of balls 33 can be adjusted according to user needs; wherein a supporting plate 12 is arranged on the upper part of the bracket 1 for providing necessary support to the turntable assembly 3 and the rotating platform 2, and the turntable assembly 3 is placed above the supporting plate 12, wherein The ball 33 is placed on the support plate 12 and connected with the support plate 12 in rolling contact to realize the rolling of the ball 33 on the support plate 12, thereby reducing the rotation resistance of the rotating platform 2. The turntable assembly 3 is mechanically connected with the shaft assembly 4 through the circular second opening 32 set in the center, so that the shaft assembly 4 can rotate in the second opening 32. A lower frame plate 23 is set below the rotating platform 2. The lower frame plate 23 is placed above the turntable assembly 3 and connected with the ball 33 in rolling contact to realize the rotation of the rotating platform 2. It is worth noting that the diameter of the ball 33 is greater than the thickness of the turntable assembly 3 to realize the rolling contact connection between the lower frame plate 23 and the ball 33, so that a movement gap is left between the lower frame plate 23 and the turntable assembly 3 to avoid contact between the two to increase the rotation resistance of the rotating platform 2, and ensure the rolling contact between the lower frame plate 23 and the ball 33, thereby reducing the resistance of the rotating platform 2 during rotation. It is worth noting that the shape of the rotating platform 2 can be set according to user needs and is not limited here. Figure 1 FIG. 4 shows a structural form in which the rotating platform 2 is in a square shape.

[0023] In a ball turntable device provided by an embodiment of the utility model, more specifically, the shaft assembly 4 includes: a fixed block 41, a shaft 42, and a nut 43. An upper frame plate 22 is arranged above the rotating platform 2, and a frame 21 is arranged in the middle of the rotating platform 2. The frame 21 is used to connect the upper frame plate 22 and the lower frame plate 23; a circular assembly hole 121 is arranged at the center of the supporting plate 12, and the fixed block 41 is arranged at the upper end of the shaft 42 and is mechanically fixedly connected to the shaft 42. The fixed block 41 is mechanically fixedly connected to the upper frame plate 22, so that the rotating platform 2 is connected to the shaft assembly 4 and performs synchronous rotation. The shaft 42 passes through the rotating platform 2, the second opening 32, the assembly hole 121 from top to bottom and is connected through the nut 43. In this way, When the rotating platform 2 rotates under the action of external force, the rotating platform 2 can drive the rotating shaft 42 to rotate in the second opening 32 and the assembly hole 121, wherein the lower part of the rotating shaft 42 is provided with a tightening part 421 with a thread, and the tightening part 421 is threadedly connected with the nut 43, and the nut 43 is arranged below the supporting plate 12, and the diameter of the assembly hole 121 should be smaller than the outer diameter of the nut 43, so that the position of the rotating shaft assembly 4 can be relatively fixed, and the rotating shaft assembly 4 can be prevented from changing the upper and lower positions at will. Through the structural design of the rotating shaft assembly 4, the use of relatively expensive large bearings is effectively reduced, which is particularly suitable for occasions where the rotation speed and precision requirements are not high, so that the ball turntable device provided by the embodiment of the utility model has a simple, reliable and practical structural design, and reduces the manufacturing cost. The rotating shaft assembly 4 can be connected to a driving mechanism such as a motor for driving to realize automatic control of the rotation of the rotating platform 2, which is convenient for application in an automated production line.

[0024] In a ball turntable device provided in an embodiment of the utility model, as a further improvement, at least four roller assemblies 11 are provided under the bracket 1 for realizing the position movement of the bracket 1, which facilitates the position adjustment of the ball turntable device in the spatial layout of the production line, and is more labor-saving and convenient to carry. At the same time, the roller assembly 11 provides necessary support for the entire ball turntable device; it is worth mentioning that a locking mechanism is provided on at least one roller assembly 11 to lock the roller assembly 11 to prevent the position of the ball turntable device from changing at will.

[0025] Compared with the prior art, the ball turntable device provided by the embodiment of the utility model has a reasonable design and a simple structure. The rotational movement of the rotating platform 2 is realized through the turntable assembly 3 and the shaft assembly 4. It has a low manufacturing cost, good economy, convenient position change, good versatility, and can meet various user needs.
