A plurality of third connecting rods 6 are connected to the outer wall of the sliding tube 5 in an intersecting manner, and the third connecting rods 6 are arranged around the axis of the sliding tube 5 in an annular array manner; one end of the third connecting rod 6 is hinged to the sliding pipe 5, the other end of the third connecting rod is hinged to the first connecting rod 7, a plurality of first connecting rods 7 are hinged to the outer wall of the guide shaft 4, the first connecting rods 7 correspond to the third connecting rods 6 one to one, and a second connecting rod 17 is arranged on one side, away from the third connecting rods 6, of the first connecting rods 7.
One ends of the first connecting rod 7 and the second connecting rod 17 are hinged with the guide shaft 4, and the other ends of the first connecting rod and the second connecting rod extend towards the inner wall of the counter bore 12; the first connecting rod 7 and the second connecting rod 17 are arranged in parallel, a fourth connecting rod 9 which is arranged horizontally is arranged between the first connecting rod 7 and the second connecting rod 17, and two ends of the fourth connecting rod 9 are hinged to the first connecting rod 7 and the second connecting rod 17 respectively.
A pressing plate is fixedly arranged at one end of the first connecting rod 7 close to the inner wall of the counter bore 12; one end of the second connecting rod 17 close to the inner wall of the counter bore 12 is rotatably connected with a driven belt pulley 11, a hinged part of the second connecting rod 17 and the guide shaft 4 is rotatably connected with a driving belt pulley 2, and a driving belt 10 is sleeved between the driven belt pulley 11 and the driving belt pulley 2. One end of the supporting seat, which is far away from the guide shaft 4, is rotatably sleeved with a rotating ring 15, the rotating ring 15 is coaxially aligned with the mounting hole, and the laser emitter is mounted on the inner wall of the rotating ring 15 and faces the center of the rotating ring 15.
The working principle of the pipe cutting machine of the present invention is described in detail below, and before machining, a pipe to be machined needs to pass through the mounting hole of the support seat, extend into the counter bore 12, and be sleeved on the guide shaft 4. When the pipe is cut, the sliding pipe 5 can be driven to slide along the guide shaft 4, the third connecting rod 6 is driven to rotate, the third connecting rod 6 drives the first connecting rod 7 to rotate, and the fourth connecting rod 9, the first connecting rod 7 and the second connecting rod 17 form a parallelogram connecting rod mechanism, so that the first connecting rod 7 rotates and simultaneously drives the second connecting rod 17 to rotate at the same angle. Like this, when first connecting rod 7 rotated, briquetting 8 just can outwards prop up to support and lean on the inner wall of pipe fitting, under the effect of expanding tightly, the pipe fitting can be fixed, the shake that produces when preventing the cutting. Meanwhile, the driving belt 10 abuts against the inner wall of the pipe fitting, the pipe fitting is supported and expanded universally, the pipe fitting is fixed, and meanwhile, when the driving belt wheel 2 is driven to rotate, the friction force between the driving belt 10 and the inner wall of the pipe fitting drives the pipe fitting to slide along the guide shaft 4, so that feeding of the pipe fitting during cutting is achieved.
When the part of the pipe fitting at the mounting hole is clamped in the rotating ring, the rotating ring rotates and simultaneously the laser emitter cuts the pipe fitting, and when a complete annular notch is formed on the pipe fitting, the front end part of the pipe fitting is completely cut off, at the moment, the cut-off part can be taken off and then the driving belt wheel 2 and the driven belt wheel 11 are driven to feed.
It can be understood that, through the above arrangement, through the synchronous rotation of the first connecting rod 7 and the second connecting rod 17, the multi-point positioning along the axial direction of the pipe fitting is realized, so that the distribution of the internal supporting force and the expansion force is more uniform, and the support is more stable.
