[0035] During cutting, the turntable mechanism 1 drives the cutter mechanism 2 to rotate. During this process, the cutter mechanism 2 automatically advances as the turntable mechanism 1 rotates, thereby achieving cutting of the pipe.

[0036] When retracting the knife, the driving member 32 is connected to the transmission member 21, the advance and retreat power assembly 31 is started, the driving member 32 outputs power to the transmission member 21, and the transmission member 21 drives the turntable mechanism 1 to move radially away from the center line of the turntable mechanism 1 to complete automatic retraction.

[0038] Embodiment 2:

[0039] Example 2 is based on Example 1:

[0040] like Figures 1 to 6 As shown, a guide seat 13 is provided on the turntable mechanism 1, and the tool mechanism 2 includes a moving seat 22 and a cutting knife 23.

[0041] The guide seat 13 is provided with a guide groove 131 along the radial direction of the turntable mechanism 1 , and the moving seat 22 is slidably arranged on the guide groove 131 . The guide groove 131 is arranged as a dovetail groove, and the moving seat 22 matches the shape of the guide groove 131 .

[0042] The transmission member 21 is disposed on the moving seat 22 and is used to transmit the power output by the driving member 32 to the moving seat 22 , so that the moving seat 22 moves along the guide groove 131 .

[0043] The cutting knife 23 is fixedly arranged on the moving seat 22 and moves synchronously with the moving seat 22 . The cutting knife 23 is arranged as a beveling knife.

[0044] The guide seat 13 cooperates with the moving seat 22 to effectively limit the moving track of the cutting knife 23 and ensure the effects of knife alignment, knife feeding and knife retraction.

[0045] As an optional embodiment, the transmission member 21 includes a transmission screw 211 , and a threaded hole is provided on the movable seat 22 along the radial direction of the turntable mechanism 1 , and the transmission screw 211 passes through the threaded hole and is threadedly matched with the threaded hole.

[0046] The advance and retreat power assembly 31 is configured as an electric power assembly, which includes a motor. The output end of the advance and retreat power assembly 31 is connected to the driving member 32 and drives the driving member 32 to rotate.

[0047] When aligning and retracting the tool, the driving member 32 is connected to the input end of the transmission screw 211, the advance and retract power assembly 31 is started, driving the driving member 32 to rotate, and the transmission screw 211 rotates accordingly. At this time, under the limiting action of the guide seat 13, the moving seat 22 moves along the guide groove 131, thereby achieving tool alignment and retracting.

[0048] The screw transmission mechanism can effectively convert the rotational motion of the output end of the advance and retreat power assembly 31 into the feed and retreat motion of the cutting knife 23 on the one hand, and it has a self-locking effect on the other hand. When the driving member 32 is not in motion, the position of the cutting knife 23 is locked. At the same time, the position of the cutting knife 23 is precisely controlled.

[0049] Furthermore, the advance and retreat power assembly 31 also includes a code disk, which is connected to the motor and can accurately control the number of rotations, thereby further improving the accuracy of the advance and retreat movement of the cutting knife 23.

[0050] As an optional embodiment, a connecting column 212 is fixedly provided at the input end of the transmission screw 211, and the driving member 32 is configured as a driving sleeve 321, which is connected to the output end of the advance and retreat power assembly 31.

[0058] As an optional embodiment, a guide rod 412 is fixedly provided in the sliding groove 4111, and the number of the guide rods 412 is set to two, which are symmetrically arranged on both sides of the telescopic component 42, and two guide holes are through-set on the slider 33, which correspond to the guide rod 412, and the guide rod 412 passes through the guide holes and slides with the guide holes.

[0059] The setting of the guide rod 412 enables the slider 33 to move along a fixed track, thereby ensuring that the driving member 32 can be accurately connected to the transmission member 21.

[0060] As an optional embodiment, the turntable mechanism 1 includes a base assembly 11 and a turntable assembly 12 rotatably disposed on the base assembly 11 . The base assembly 11 is formed by docking two C-shaped bases, and the turntable assembly 12 is formed by docking two C-shaped tracks.

[0061] The tool mechanism 2 is fixedly disposed on the turntable assembly 12 and rotates synchronously with the turntable assembly 12 .

[0062] When cutting the pipe, the telescopic assembly 42 drives the slider 33 to move away from the turntable mechanism 1, thereby separating the driving member 32 from the transmission member 21. After that, the turntable assembly 12 rotates along the base assembly 11, and the tool mechanism 2 rotates synchronously therewith, thereby achieving cutting of the pipe.

[0063] As an optional embodiment, a transmission ratchet 213 is fixedly provided at the input end of the transmission screw 211, and a connecting column 212 is fixedly provided on the end face of the transmission ratchet 213.

[0064] During the process of cutting the pipe, the tool mechanism 2 rotates one circle driven by the turntable mechanism 1, and the transmission ratchet 213 engages with the feed block 214 and rotates a certain angle under the action of the feed block 214, so that the cutting knife 23 is fed a certain distance, thereby realizing intermittent automatic feeding.

[0065] The cutting blade 23 is adaptively fed along with the rotation of the turntable mechanism 1, which can effectively improve the pipe cutting effect.

[0066] As an optional embodiment, the number of the tool mechanism 2, the advance and retreat drive mechanism 3 and the telescopic mechanism 4 is set to two; the two tool mechanisms 2 are arranged opposite to each other; the two advance and retreat drive mechanisms 3 are arranged opposite to each other; and the two telescopic mechanisms 4 are arranged opposite to each other.

[0067] The two sets of tool mechanisms 2, the advance and retreat drive mechanism 3 and the telescopic mechanism 4 cooperate with each other to further improve the operation efficiency on the basis of ensuring the pipeline cutting effect.

[0068] The working process of the automatic tool setting, tool feeding and tool retracting device for deep-sea unmanned collaborative pipeline cutting operation is as follows:

[0069] Step I: Automatic tool setting before operation.

[0070] First, the telescopic component 42 extends out, pushing the slider 33 to move along the sliding groove 4111, and connecting the drive sleeve 321 to the connecting column 212; then, the advance and retreat power component 31 is started, driving the drive sleeve 321 to rotate forward, and the connecting column 212, the transmission ratchet 213 and the transmission screw 211 rotate synchronously, and the moving seat 22 and the cutting knife 23 feed along the guide groove 131 to align the knife; when the cutting knife 23 has completed the alignment, the telescopic component 42 retracts to separate the drive sleeve 321 from the connecting column 212.

[0071] Step II: Automatic feed during operation.

[0072] The turntable assembly 12 rotates along the machine base assembly 11, and the tool mechanism 2 thereon rotates synchronously therewith. When the transmission ratchet 213 rotates to the position of the feed block 214, the two are engaged, and the transmission ratchet 213 and the transmission screw 211 rotate a certain angle, so that the movable seat 22 and the cutting knife are fed to a certain position along the guide groove 131, completing a feeding action; thereafter, as the turntable assembly 12 continues to rotate, the cutting knife 23 automatically feeds.

[0073] Step III: Automatically retract the tool after operation.

[0074] First, the telescopic component 42 extends out, pushing the slider 33 to move along the sliding groove 4111, and connecting the drive sleeve 321 to the connecting column 212; then, the advance and retreat power component 31 is started, driving the drive sleeve 321 to rotate in the opposite direction, and the connecting column 212, the transmission ratchet 213 and the transmission screw 211 rotate synchronously therewith, and the moving seat 22 and the cutting knife 23 move backward along the guide groove 131 to retract; when the cutting knife 23 has completed retraction, the telescopic component 42 retracts to separate the drive sleeve 321 from the connecting column 212.
