Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
Please refer to fig. 1 to 4. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.
Referring to fig. 1 to 4, the present invention provides a platform rotation device, in an embodiment of the present invention, when the turntable 1 is required to act, the slide block 5 at the output end of the driving piece 3 slides along the guide rod 4 at the output end of the driving piece 3, the guide rod 4 is connected in the guide block 6 in a sliding way, and the guide rod 4 is limited by a guide rod lantern ring 7 arranged at the tail end of the guide block 6, the size of the guide rod lantern ring 7 is matched with that of the guide rod 4, the guide rod 4 is prevented from displacing in other directions in the process that the driving piece 3 drives the guide rod 4, a connecting block 8 is arranged between the sliding block 5 and the guide rod 4, the connecting block 8 moves along with the guide rod 4, thereby driving the slide block 5 to move transversely along with the guide rod 4, the guide rod 4 is arranged along the tangential direction of the turntable 1, the driving part 3 adopts a stepping motor, and other devices capable of replacing the stepping motor can be used for replacement;
