Referring to fig. 1 to 3, the pipe clamping and rotating device 100 is used for pipe cutting equipment, and includes a fixing base 1, a rotating sleeve 2, a clamping structure 3 and a driving ring 4: the rotary sleeve 2 is rotatably arranged on the fixed seat 1 along an axis in the left-right direction, and the rotary sleeve 2 is provided with a left-right through accommodating cavity which is used for accommodating a pipe fitting in the left-right direction; the clamping structure 3 comprises a plurality of propping parts 31, wherein the propping parts 31 are arranged in the accommodating cavity and distributed along the circumferential direction of the accommodating cavity, and are movably arranged along the radial direction towards the center of the accommodating cavity so as to have a first position for simultaneously propping against the pipe fitting 200 and a second position for separating from the pipe fitting 200; and the driving ring 4 is sleeved on the rotating sleeve 2 and is rotatably arranged along an axis in the left-right direction, the driving ring 4 is provided with a first rotating stroke section and a second rotating stroke section on the rotating stroke, the driving ring 4 drives a plurality of jacking parts 31 to synchronously move to the first position on the first rotating stroke section, and the driving ring 4 drives the rotating sleeve 2 to rotate on the second rotating stroke.

The driving ring 4 rotates along the axis of the left-right direction, and converts the circumferential rotation of the driving ring 4 into radial movement of the propping part 31, and the transmission mode can be in various forms, for example, the transmission mode can be realized through a cam transmission mechanism, the driving ring 4 acts on a cam shaft to drive the cam to rotate through the cam shaft, and then the cam is lifted up to act with the propping part 31 through the cam so as to convert the rotation into radial translation, but the lifting stroke of the cam transmission mechanism is smaller, and is difficult to provide enough movement for the propping part 31, and in this embodiment, a plurality of mounting holes 21 are arranged on the periphery side of the rotating sleeve 2; the pipe fitting clamping and rotating device 100 further comprises a first transmission structure 5, wherein the first transmission structure 5 comprises a plurality of transmission screws 51, a plurality of bevel gears 52 and bevel gears 53, the plurality of transmission screws 51 penetrate through the corresponding mounting holes 21, and the plurality of tightening parts 31 are respectively arranged on the corresponding transmission screws 51; the bevel gears 52 are arranged on the rotary sleeve 2 corresponding to the mounting holes 21 and are rotatably arranged along the axis along the radial direction facing the center of the accommodating cavity, threaded holes communicated with the mounting holes 21 are formed in the bevel gears 52, and the transmission screw 51 extends into the threaded holes; and the bevel gear ring 53 is coaxially disposed on the drive ring 4 and is engaged with the bevel gears 52. The bevel gears 52 can be synchronously driven to rotate by the driving of the bevel gears 53 on the driving ring 4, so that the bevel gears 52 drive the driving screw 51 to perform circumferential expansion and contraction under the driving action of the screw pair, that is, the tightening part 31 is driven to movably adjust along the radial direction towards the center of the accommodating cavity, and the combination mode of gear transmission and screw transmission can provide a larger movement amount for the tightening part 31, and meanwhile, the structure is compact.
Since the forces act mutually, the bevel gear 52 drives the drive screw 51 to axially move, and the bevel gear 52 itself is subject to the same axial force, that is, the bevel gear 52 needs to be mounted to the rotating sleeve 2 through an axial limiting structure, which is not limited by the embodiment of the present utility model.
It should be noted that, the tightening portion 31 only performs radial movement toward the center of the accommodating cavity, so that the driving screw 51 should perform axial movement of rotation stopping, and in this embodiment, a plurality of rotation stopping holes are further provided on the circumferential side of the rotating sleeve 2 corresponding to the plurality of mounting holes 21; each tightening portion 31 is provided with a rotation stopping rod 6, and the rotation stopping rod 6 and the corresponding mounting hole 21 are arranged in parallel and are adapted to extend into the corresponding rotation stopping hole. By the cooperation of the rotation stop lever 6 and the rotation stop hole, the rotation freedom degree of the drive screw 51 can be limited, and it can be understood that the rotation stop lever 6 is disposed at the lateral side of the drive screw 51 in the left-right direction and keeps consistent with the extending direction of the drive screw 51.
