Connecting device of vacuum hard pipe and vacuum flexible pipe

The utility model discloses a connecting device of a vacuum hard pipe and a vacuum flexible pipe. The connecting device of the vacuum hard pipe and the vacuum flexible pipe comprises a machine frame. An electrical control mechanism, a locating mechanism, transversely-moving mechanisms, a vacuum flexible pipe clamping mechanism, a hoop assembling mechanism and a vacuum hard pipe clamping mechanism are arranged on the machine frame. The transversely-moving mechanisms drive the vacuum flexible pipe clamping mechanism and the vacuum hard pipe clamping mechanism to conduct transverse motion. Power machines of the transversely-moving mechanisms and a power machine of the locating mechanism are respectively connected with the electrical control mechanism. The vacuum hard pipe and the vacuum flexible pipe are connected in the mode of automatic control, the work efficiency is high, and the uniformity of connection is guaranteed.
