The invention relates to the technical field of
machining, in particular to inner supporting type
pipe end face automatic
welding and
cutting groove
machining equipment. The inner supporting type
pipe end face automatic
welding and
cutting groove
machining equipment comprises a
machine body, an expansion mechanism
assembly, a rotating fluted disc, a driving transmission mechanism and a mechanical
cutting executing mechanism, wherein the
machine body is in a circular ring shape and is hollow, the rotating fluted disc is also in a circular ring shape and is installed in the
machine body, the top of the machine body is provided with a mounting disc, the mounting disc is fixedly connected with the rotating fluted disc in the machine body, and the mechanical cutting executing mechanism is fixedly installed on the mounting disc; and the expansion mechanism
assembly comprises a driving device, expansion adjusting rods and expansion blocks, each expansion block is in a circular arc shape, the
radian of one side of each expansion block is consistent with that of the inner wall of a
pipe, the other side of each expansion block is fixedly connected with the corresponding expansion adjusting rod, the other ends of the expansion adjusting rods penetrate through the machine body and are connected with the driving device, and the driving device is fixed to the machine body. Therefore, the defects that an existing beveling machine for the pipe is large in size and weight, cannot automatically center and clamp and the like are overcome. The inner supporting type pipe end face automatic
welding and cutting groove machining equipment is mainly used for machining the pipe.
