Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A cutting machine for producing precision seamless steel pipes, comprising a cutting machine frame 1. A telescopic electric rod 2 is fixedly connected to the top of the cutting machine frame 1. A motor 3 is fixedly connected to the bottom of the telescopic electric rod 2. An output end of the motor 3 is fixedly connected to a cutting disc 4. An adjusting mechanism 5 is arranged inside the cutting machine frame 1. The adjusting mechanism 5 includes a rotating shaft 51. One end of the rotating shaft 51 is fixedly connected to a crank 52. The other end of the rotating shaft 51 is fixedly connected to a bevel gear set 53. A threaded rod 54 is fixedly connected to the surface of the bevel gear set 53. Two groups of sliders 55 are movably connected to the surface of the threaded rod 54. A clamping roller 6 is fixedly connected to the surface of the slider 55. A protection mechanism 7 is arranged inside the cutting machine frame 1. The protection mechanism 7 includes a protection plate 71. An observation window 72 is fixedly connected to the surface of the protection plate 71. Vertical plates 73 are fixedly connected to both sides of the protection plate 71. An auxiliary plate 74 is fixedly connected to the top of the protection plate 71. A plug rod 75 is inserted into the vertical plate 73. A limiting plate 76 is fixedly connected to the surface of the plug rod 75. A spring 77 is fixedly connected to the surface of the limiting plate 76. One end of the plug rod 75 is fixedly connected to a pull rod 78. The protection mechanism 7 is provided. When cutting the steel pipe, pull the pull rod 78 outwards. The pull rod 78 drives the plug rod 75 to move out of the vertical plate 73. At this time, the spring 77 is compressed. Lift the protection plate 71 upwards through the auxiliary plate 74 to a proper position. Release the pull rod 78. Under the action of the spring 77, the plug rod 75 is pressed into the vertical plate 73 to fix the position of the protection plate 71, preventing sparks from splashing on the operator's body when cutting the steel pipe and solving the problem that the user's hand or face is damaged. The adjusting mechanism 5 is provided. By rotating the crank 52, the rotating shaft 51 is driven to rotate, driving the bevel gear set 53 to rotate, and then the threaded rod 54 rotates. Two groups of opposite threads are arranged on its surface, and then the two groups of sliders 55 on its surface are driven to move towards or away from each other, thereby changing the distance between the two groups of clamping rollers 6, and then different diameters of steel pipes can be adapted, which is more convenient to use.

[0024] Further, an output end of the telescopic electric rod 2 penetrates through the top of the cutting machine frame 1 and is fixedly connected to the surface of the motor 3. Turn on the motor 3 to drive the cutting disc 4 to rotate. The cutting disc 4 cuts the steel pipe by the telescopic electric rod 2 extending.

[0025] Further, two groups of opposite threads are symmetrically arranged on the surface of the threaded rod 54. The two groups of sliders 55 are respectively matched with the two groups of threads. The rotation of the threaded rod 54 drives the two groups of sliders 55 on its surface to move towards or away from each other, thereby changing the distance between the two groups of clamping rollers 6.

[0026] Further, slots are formed on the surface of the cutting machine frame 1. The protection plate 71 and the vertical plates 73 are slidably connected in the slots. By pulling the auxiliary plate 74, the position of the protection plate 71 can be adjusted.

[0027] Further, a first groove is formed inside the cutting machine frame 1. The inserting rod 75, the limiting plate 76 and the spring 77 are slidably connected inside the first groove. Two second grooves are respectively formed in the upper and lower surfaces of the two vertical plates 73. The inserting rod 75 is inserted into the second groove to fix the position of the protection plate 71.

[0028] Further, one end of the spring 77 is fixedly connected to the surface of the limiting plate 76, and the other end of the spring 77 is fixedly connected to the inner wall of the first groove. When the pull rod 78 is pulled outwards, the pull rod 78 drives the inserting rod 75 to move out of the vertical plate 73. At this time, the spring 77 is compressed. When the pull rod 78 is released, under the action of the spring 77, the inserting rod 75 is pressed into the vertical plate 73.

[0029] Further, the inner surface of the spring 77 does not contact the outer surface of the inserting rod 75, and the inserting rod 75 and the spring 77 do not interfere with each other during movement.

[0030] Working principle: During use, according to the diameter of the steel pipe, the crank 52 is rotated to drive the rotating shaft 51 to rotate, driving the bevel gear set 53 to rotate, and then the threaded rod 54 to rotate. There are two sets of opposite threads on its surface, which drives the two sliders 55 on its surface to move towards or away from each other, thereby changing the distance between the two clamping rollers 6 to clamp the steel pipe. The pull rod 78 is pulled outwards, and the pull rod 78 drives the inserting rod 75 to move out of the vertical plate 73. At this time, the spring 77 is compressed. The protection plate 71 is lifted upwards to a suitable position through the auxiliary plate 74. When the pull rod 78 is released, under the action of the spring 77, the inserting rod 75 is pressed into the vertical plate 73 to fix the position of the protection plate 71, preventing sparks from splashing on the operator's body when cutting the steel pipe. The motor 3 is turned on to drive the cutting disc 4 to rotate, and the cutting disc 4 cuts the steel pipe by extending the electric telescopic rod 2.
