DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0023] Embodiment: A clamping device for a pipe cutting machine, such as Figures 1-6As shown, it includes a frame 1, a first motor 3, a protective cover 4, a blade 5, a second motor 6 and a clamping assembly. The left and right sides of the frame 1 are provided with a placement slot 2 for limiting the position of the pipe. The first motor 3 is installed on the left side of the rear of the frame 1 by screws. The output shaft of the first motor 3 passes between the two sides of the inside of the frame 1. The output shaft of the first motor 3 is rotatably connected to the protective cover 4. The right side of the protective cover 4 is rotatably connected to the blade 5. The left side of the protective cover 4 is installed with a second motor 6 by screws. The output shaft of the second motor 6 passes through the right side of the protective cover 4 and is rotatably connected to the blade 5. A clamping assembly is provided at the front of the frame 1, and the clamping assembly includes a cylinder 7 and a slider 8. , a fixed block 9, a first electric push rod 10, a first chuck 11 and a second chuck 12, the cylinder 7 is installed inside the rear side of the frame 1 by screws, the telescopic rod of the cylinder 7 is connected to the slider 8, the bottom of the slider 8 is slidably connected to the middle of the frame 1, the front part of the frame 1 is connected to the fixed block 9 by welding, the first electric push rod 10 is installed inside the slider 8 and the fixed block 9 by screws, the telescopic rod of the first electric push rod 10 inside the slider 8 is connected to the first chuck 11, the telescopic rod of the first electric push rod 10 inside the fixed block 9 is connected to the second chuck 12, the first chuck 11 and the second chuck 12 are symmetrical at one end close to each other.

[0024] like Figure 1 and Figure 5-Figure 6 As shown, a chip box 17 is also included. The front middle part of the frame 1 is slidably connected to the chip box 17. A handle is provided at the front of the chip box 17. The debris generated during the cutting process will fall into the chip box 17 and be collected. The chip box 17 filled with debris can be smoothly taken out through the handle of the chip box 17.

[0025] When the device needs to be used, the operator first places the pipe in the placement groove 2, and then starts the first motor 3 and the second motor 6. The output shaft of the first motor 3 drives the protective cover 4 and the blade 5 to rotate downward, and the output shaft of the second motor 6 drives the blade 5 to rotate. The protective cover 4 effectively prevents the blade 5 from accidentally injuring the operator when rotating, increasing protection. When the blade 5 contacts the pipe, the blade 5 will cut the pipe. After the cutting is completed, the first motor 3 and the second motor 6 can be turned off. If it needs to be used again, the above operation is repeated; when the pipe is unstable in the placement groove 2 and needs to be fixed, the operator first places the pipe in the placement groove 2, and then starts the cylinder 7. The telescopic rod of the cylinder 7 extends to move the slider 8 forward, so that the first clamp 11 and the second clamp 12 contact to clamp the pipe. After clamping, the pipe can be cut. After the cutting is completed, the cylinder 7 is turned off, and the telescopic rod of the cylinder 7 retracts to make the slider 8 and the first When the cutting tool 11 is in the working state, the first and second clamps 11 and 12 are moved downwards to be reset.

[0026] like Figure 1 、 Figure 4 and Figure 6 As shown, it also includes a measuring rod 13, a screw 14, a second electric push rod 15 and a baffle 16. The measuring rod 13 is slidably connected to the right front side of the frame 1. A plurality of threaded holes are provided on the measuring rod 13. The top left side of the measuring rod 13 is threadedly connected with a screw 14. The screw 14 is adapted to the threaded hole of the measuring rod 13. The screw 14 is threadedly connected to the top front right side of the frame 1. The length of the pipe cutting can be adjusted and controlled by cooperating with the measuring rod 13 and the screw 14. The right side of the measuring rod 13 is connected to the second electric push rod 15 by welding. The telescopic rod of the second electric push rod 15 is connected with a baffle 16. The baffle 16 effectively blocks the left and right movement of the pipe.

[0027] When it is necessary to control the length of the cut pipe, the operator first places the pipe in the placement groove 2, and then uses a tool to turn the screw 14 counterclockwise so that the screw 14 no longer fixes 13 through the threaded hole on the measuring rod 13, and at this time, the measuring rod 13 is pushed to move it left and right, and the length of the cut pipe can be checked by the scale of the measuring rod 13. When the measuring rod 13 is pushed to the right to move to the appropriate position, because there are multiple threaded holes on the measuring rod 13, the length of the pipe cutting can be adjusted. The operator uses a tool to tighten the screw 14 clockwise to fix the measuring rod 13, and then starts the second electric push rod 15. The telescopic rod of the second electric push rod 15 is extended. The baffle 16 moves backward. When the baffle 16 contacts one end of the pipe, the baffle 16 blocks the left and right movement of the pipe, so that the longer pipe can be cut. When the measuring rod 13 moves to the left to a suitable position, the operator can use a tool to tighten the screw 14 clockwise to fix the measuring rod 13, and then start the second electric push rod 15. The telescopic rod of the second electric push rod 15 is extended to move the baffle 16 backward. When the baffle 16 contacts one end of the pipe, the baffle 16 blocks the left and right movement of the pipe, so that the shorter pipe can be cut. After the cutting is completed, the second electric push rod 15 is closed, and the telescopic rod of the second electric push rod 15 is retracted to move the baffle 16 forward to reset.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
