DETAILED DESCRIPTION

[0013] The specific content of the utility model will be described in detail in combination with the drawings and examples.

[0014] As Figure 1 ,Figure 2 and Figure 3 As shown, this utility model provides a precision steel pipe cutting device, including a base 1, a U-shaped plate 2 that can move laterally on the base 1, a lifting connecting plate 3 on one side of the U-shaped plate 2, a horizontal tube 31 on the connecting plate 3, two symmetrically distributed connecting strips 32 on the horizontal tube 31, the horizontal tube 31 being located between the two connecting strips 32, a push rod 33 penetrating the horizontal tube 31 on the connecting strip 32, and a spring 34 fixed between the connecting strip 32 and the horizontal tube 31; an electric telescopic rod 35 fixed inside the horizontal tube 31, the telescopic end of the electric telescopic rod 35 being fixed with a moving block 36 that, after movement, pushes the two push rods 33 away from each other; a cutting assembly and a bearing frame 4 for supporting the steel pipe are provided on the base 1, the bearing frame 4 being located between the cutting assembly and the U-shaped plate 2. After placing the steel pipe inside the U-shaped plate 2, ensure the bottom of the steel pipe contacts the bottom of the U-shaped plate 2. Then adjust the height of the connecting plate 3 so that the axis of the horizontal pipe 31 corresponds to the axis of the steel pipe. Insert one end of the steel pipe into the horizontal pipe 31. Then activate the electric telescopic rod 35 to push the moving block 36 (the top and bottom surfaces of the moving block 36 are inclined, and the ends of the two push rods 33 inside the horizontal pipe 31 contact the top and bottom surfaces of the moving block 36 respectively). After the moving block 36 moves (moving to the right, so that...), it moves to the right. Figure 1 If the position shown in the diagram is reached, the push rod 33 can be pushed to move the two connecting strips 32 (which can be made of rubber) away from each other, and then the spring 34 will be stretched so that the two connecting strips 32 will abut against the inner wall of the steel pipe, thus fixing the steel pipe. Then the bearing frame 4 supports the part of the steel pipe away from the U-shaped plate 2, so that when the U-shaped plate 2 moves the steel pipe, the bearing frame 4 cooperates with the U-shaped plate 2 to allow the cutting component to complete the cutting operation of the steel pipe. Subsequently, as the U-shaped plate 2 moves continuously, the steel pipe can be cut into several small segments. The number of connecting strips 32 can be set to four, so that the four sides of the moving block 36 (front, back, top and bottom are all inclined) are set accordingly, so that when the moving block 36 moves, the four connecting strips 32 move away from the horizontal pipe 31, so as to better abut against the inner wall of the steel pipe for fixing.

[0015] like Figure 1 and Figure 2As shown, the inner side of the U-shaped plate 2 is provided with two front and rear symmetrical stop plates 22, and two first automatic telescopic rods 21 are fixed on the U-shaped plate 2, and the telescopic ends of the two first automatic telescopic rods 21 are connected with the two stop plates 22 respectively; the connecting plate 3 is located on the side of the U-shaped plate 2 away from the bearing frame 4, and the base 1 is fixed with a second automatic telescopic rod 41, the telescopic end of which is connected with the bearing frame 4. When the steel pipe is placed on the inner side of the U-shaped plate 2, the cross pipe 31 enters the steel pipe and is fixed on the steel pipe through the two connecting strips 32, then the two first automatic telescopic rods 21 are started to make the two stop plates 22 close to each other to clamp the steel pipe and further fix the steel pipe, thereby ensuring the stability of the steel pipe during cutting; when the U-shaped plate 2 drives the steel pipe to move transversely, the second automatic telescopic rod 41 is started to make the bearing frame 4 move downward and separate from the steel pipe, then the U-shaped plate 2 drives the steel pipe to start transverse movement, thereby avoiding friction between the bearing frame 4 and the surface of the steel pipe.

[0016] As shown in Figure 1 and Figure 2 , the base 1 is fixed with a fixed frame 11 between the bearing frame 4 and the U-shaped plate 2, and the inner side of the fixed frame 11 is rotatably connected with a rotating rod 12, the top surface of which is flush with the top surface of the inner side of the U-shaped plate 2. When the steel pipe needs to move transversely, the bearing frame 4 moves downward, and then the U-shaped plate 2 drives the steel pipe to move, so that the rotating rod 12 rotates to assist the movement of the steel pipe.

[0017] As shown in Figure 1 , Figure 2 and Figure 4 , the cutting assembly comprises a U-shaped frame 6 fixed on the base 1, the inner side of the U-shaped frame 6 is provided with a liftable protective cover 61, the protective cover 61 is fixed with a first motor 62 inside, the rotating shaft of the first motor 62 is fixed with a cutting disc 63, and the bottom of the side of the protective cover 61 close to the bearing frame 4 is provided with a notch 66; the U-shaped frame 6 is fixed with a hydraulic rod 64 for driving the protective cover 61, and the U-shaped frame 6 is provided with a transparent plastic plate 65. The telescopic end of the hydraulic rod 64 is fixed with the top of the protective cover 61, and the main body of the first motor 62 is fixed with the inner wall of the protective cover 61 through a fixed rod; starting the hydraulic rod 64 can drive the protective cover 61 to move downward, and starting the first motor 62 can drive the cutting disc 63 to rotate, when the steel pipe enters the notch 66 at the bottom of the U-shaped frame 6, the cutting disc 63 contacts with the steel pipe, then the steel pipe can be cut, and the protective cover 61 can block the debris generated when the steel pipe is cut, thereby avoiding the debris flying everywhere; the protective cover 61 is also made of transparent plastic, and the setting of the plastic plate 65 can enable the worker to observe the situation inside the protective cover 61; the U-shaped frame 6 is arranged in a U-shaped manner, and the U-shaped frame 6 can also be arranged in an L-shaped manner, and when the U-shaped frame 6 is arranged in an L-shaped manner, the plastic plate 65 is not needed.

[0018] As shown in Figure 2 and Figure 4As shown, both sides of the gap 66 are provided with a jack 67 fixed in the jack hole. Two sponge blocks 8 are arranged in the gap 66, and an iron rod 81 is fixed in the jack hole of the gap 66. According to the diameter of the steel pipe, the sponge block 8 can be removed and replaced with a sponge block 8 of corresponding thickness, and then the iron rod 81 is inserted into the jack hole of the gap 66, so that the iron rod 81 is in contact with the magnet 67, and the iron rod 81 is adsorbed to fix the sponge block 8. After the steel pipe enters the gap 66, it is in contact with the sponge block 8 to reduce the situation that the debris is scattered outside the protective cover 61 when the steel pipe is cut.

[0019] As shown in Figure 1 and Figure 2 The base 1 is fixed with a third automatic telescopic rod 7, and the telescopic end of the third automatic telescopic rod 7 is fixed with a bearing plate 71. The bearing plate 71 is placed with a collecting frame 72 located directly below the protective cover 61. The top of the bearing plate 71 is fixed with an L-shaped limiting plate 73, and the collecting frame 72 is located on the inner side of the limiting plate 73. The part of the steel pipe to be cut is located directly above the collecting frame 72. When the protective cover 61 moves downward to cut the steel pipe with the cutting disc 63, the bottom of the protective cover 61 is in contact with the top of the collecting frame 72, and the telescopic end of the third automatic telescopic rod 7 drives the bearing plate 71 to move downward synchronously with the protective cover 61, so that the cutting disc 63 cuts the steel pipe, and the cut part of the steel pipe directly enters the collecting frame 72, which is convenient for the subsequent collection and transfer of the steel pipe by the staff, and further avoids the scattering of debris when the steel pipe is cut. The third automatic telescopic rod 7 can also be replaced by a telescopic cylinder, which includes a sleeve, a spring fixed in the sleeve, a vertical rod slidingly connected in the sleeve and fixed with the spring, and the vertical rod is in contact with the bottom of the bearing plate 71, so that when the protective cover 61 applies pressure to the collecting frame 72, the vertical rod can compress the spring to move the bearing plate 71 downward. The limiting plate 73 can effectively limit the collecting frame 72 to avoid misplacement of the collecting frame 72.

[0020] As shown in Figure 1 and Figure 2 The base 1 is fixed with a second motor 9, and a lead screw 91 is fixed on the rotating shaft of the second motor 9. A moving plate 92 is threadedly connected to the lead screw 91, and the moving plate 92 is slidingly connected to the base 1 and connected to the bottom of the U-shaped plate 2. A fourth automatic telescopic rod 93 is fixed on the moving plate 92 and connected to the connecting plate 3. The rotation of the lead screw 91 can be achieved by starting the second motor 9 (the second motor 9 is a servo motor), so that the moving plate 92 slides horizontally on the base 1, and the U-shaped plate 2 can be moved with the moving plate 92, so that the steel pipe can be transported in the direction of the cutting disc 63. The fourth automatic telescopic rod 93 can drive the connecting plate 3 to move upward or downward to change the height of the horizontal pipe 31.

[0021] AsFigure 1 and Figure 2 As shown in the figure, the cross pipe 31 is fixed with a support rod 5 which is slidingly connected with the connecting plate 3, and the connecting plate 3 is threadedly connected with a screw rod 51 which is rotatably connected with one end of the cross pipe 31. The support rod 5 can increase the stability of the cross pipe 31, and when fine adjustment of the position of the cross pipe 31 is needed, the cross pipe 31 can be pushed to move laterally after the screw rod 51 is rotated.
