Abstract

This utility model relates to the technical field of cylinder filling devices, and discloses an automatic switching device for simultaneously filling multiple cylinders. It includes a device body and a vent pipe fixedly connected to one side of the device body. A telescopic cylinder is fixedly connected to the top of the device body, and two sets of telescopic cylinders are provided. A mounting frame is fixedly connected to the output end of the telescopic cylinder. The device body has a placement structure that serves to fix multiple sets of cylinders. The placement structure includes a servo motor fixedly connected to the outside of the device body. This utility model, through the arrangement of telescopic cylinders, clamping blocks, placement grooves, and sliding frames, achieves the effect of conveniently fixing multiple sets of cylinders simultaneously by operators, improving the efficiency of the filling operation. It solves the problem that existing filling switching devices often require manual fixing of the cylinders and filling operations, which easily leads to misalignment between the filling port and the cylinder.
