[0002] Pipes are usually very long when they are produced in the factory. Workers need to use a pipe cutter to cut the required length of pipe from the whole pipe before use. Usually before cutting, workers use a ruler to measure the required length of the pipe and then use a stylus to mark the pipe. Then, the pipe is placed on the pipe cutter, and the pipe cutter cuts the required pipe at the cutting mark.
[0003] When workers use a ruler to measure the length of the pipe, it is difficult to accurately align the zero mark of the ruler with the end of the pipe due to the inevitable shaking of the hands and the accuracy of the naked eye. As a result, after cutting the pipe, the pipe needs to be measured again, and the excess length of the pipe is cut off and discarded, resulting in waste of pipe. Summary of the invention

[0028] Reference Figure 1-4 ,
[0029] A precise positioning structure of a pipe cutting machine includes: a support device 10, a guide rail 20, an abutment 30, a locking member 40 and a scale 50. The support device 10 is placed on the side of the pipe input of the pipe cutting machine. The support device 10 includes: a bracket 11 and a conveying roller 12. Multiple groups of conveying rollers 12 are arranged side by side along the length direction of the guide rail 20, and the two ends of the multiple groups of conveying rollers 12 are respectively rotatably connected with the bracket 11 through bearings. Workers can put the pipes on the multiple groups of conveying rollers 12, and then push the pipes to the pipe cutting machine. At this time, the conveying rollers 12 rotate, reducing the friction on the pipes, and the workers save effort in operation. The guide rail 20 is fixedly connected to the support device 10 by bolts, specifically the upper end of one side of the bracket 11. A groove 202 is formed at the upper end of the guide rail 20, and the scale 50 is clamped in the groove 202 of the guide rail 20 along the length direction of the guide rail 20, so that workers can replace the scale 50. The abutment member 30 forms an abutment surface 321, which is used to abut against the end of the pipe extending out of the pipe cutting machine, thereby limiting the position of the pipe. The abutment surface 321 is perpendicular to the length direction of the guide rail 20, and the abutment member 30 contacts and fits one side of the guide rail 20, so that when the pipe contacts the abutment surface 321, the abutment member 30 can provide stable support for the pipe. A part of the locking member 40 is connected to the abutment member 30, and the other part of the locking member 40 is connected to the guide rail 20, which is used to lock the abutment member 30 at the position of the guide rail 20 required by the worker. The worker can know the exact length of the pipe to be cut according to the reading of the scale aligned with the upper edge of the abutment member 30.
[0030] Specifically, the abutment member 30 includes: a support plate 31 and an abutment block 32. The support plate 31 is welded from an existing iron plate, and the abutment block 32 is cut from an existing square tube steel. The abutment block 32 forms an abutment surface 321 on the side away from the support plate 31, and the abutment block 32 is welded and fixed to the support plate 31 on the side facing the support plate 31. The side of the support plate 31 facing the guide rail 20 forms a sliding contact with the side of the guide rail 20. A part of the locking member 40 is connected to the support plate 31, and another part of the locking member 40 is connected to the guide rail 20, so as to lock the support plate 31 and the abutment block 32 at any position on the guide rail 20.
[0031] Specifically, the locking member 40 includes: a screw 41 and a nut 42. The screw 41 is inserted into and connected to the support plate 31, and the nut 42 is slidably connected to the guide rail 20. The screw 41 and the nut 42 are threadedly connected. When the support plate 31 and the abutment block 32 need to be moved, the worker loosens the screw 41 from the nut 42 so that the screw 41 no longer presses the support plate 31 against the guide rail 20. At this time, the support plate 31 and the abutment block 32 can slide back and forth along the guide rail 20. After the support plate 31 and the abutment block 32 slide to the required scale, the worker tightens the screw 41 on the nut 42, and the screw 41 presses the support plate 31 against the guide rail 20 again, so that the support plate 31 and the abutment block 32 are fixed relative to the guide rail 20, so that the abutment block 32 can stably abut the end of the pipe.
[0032] Specifically, in the length direction of the guide rail 20, the guide rail 20 forms a T-shaped guide groove 201, and the nut 42 is placed in the T-shaped guide groove 201. The screw 41 includes a rod and a head. One side of the T-shaped guide groove 201 penetrates the side of the guide rail 20 toward the support plate 31 to accommodate the rod of the screw 41. The diameter of the rod is the same as the width of the opening of the T-shaped guide groove 201 penetrating the guide rail 20. When the support plate 31 and the abutment block 32 are moved, the rod slides along the T-shaped guide groove 201, and the T-shaped guide groove 201 supports the screw 41. The tail end of the rod is inserted into the T-shaped guide groove 201 and threadedly connected with the nut 42, and the head abuts against the side of the support plate 31 away from the guide rail 20. The thickness of the nut 42 is the same as the width of the other side of the T-shaped guide groove 201, and the length of the opposite side of the nut 42 is the same as the height of the T-shaped guide groove 201, so that the nut 42 can be embedded in the T-shaped guide groove 201 and slide along the T-shaped guide groove 201, wherein the thickness of the nut 42 and the length of the opposite side of the nut 42 are both commonly used concepts in the mechanical field.
[0033] Specifically, the head of the screw 41 forms a screwdriver slot, and the screwdriver handle can be one of the common cross slots, slots and hexagonal slots. In this embodiment, the hexagonal slot is selected. Compared with the cross slot and the slot, when the worker uses a hexagonal wrench to vigorously turn the screw 41, it is less likely to cause damage to the hexagonal slot, and the durability is higher.
[0034] In another embodiment, the abutment member 30 further includes a rotating wheel 60. The rotating wheel 60 is rotatably connected to the end of the support plate 31 away from the guide rail 20 via a pin, and the wheel surface of the rotating wheel 60 contacts the upper end of the bracket 11. When the support plate 31 slides along the guide rail 20, one end of the support plate 31 is supported on the guide rail 20 via the screw 41, and the other end of the support plate 31 is supported on the bracket 11 via the rotating wheel 60, thereby avoiding a rapid decrease in the service life of the screw 41 due to the suspension of only one end of the support plate 31 by the screw 41.
[0035] Specifically, the support member further includes: a universal foot 70. The bending foot is selected from existing products, and multiple groups of universal feet 70 are provided, and four groups are provided in this embodiment. The four groups of universal feet 70 are respectively connected with the four corners of the lower end of the bracket 11 by threads, thereby improving the stability of the bracket 11 in supporting the pipe on the uneven ground.
