DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5As shown, an automatic pipe sawing machine for automobile oil pipes comprises a workbench 1; a placing frame 11 is installed at the end of the workbench 1; a pipe sawing machine body 12 is installed on the inner wall of the top of the workbench 1; a connecting plate 13 is fixedly connected to the end of the pipe sawing machine body 12; two groups of first baffles 14 are installed on the end of the connecting plate 13; the two groups of the first baffles 14 are symmetrically arranged; a second baffle 15 is slidably connected to the inner wall of the first baffle 14; a connecting block 16 is fixedly connected to the middle of the second baffle 15; a plurality of first springs 17 are fixedly connected to the top of the connecting block 16; and a plurality of first springs 17 are fixedly connected to the top of the plurality of first springs 17. At the bottom of the first baffle plate 14; when working, the staff needs to install the workbench 1 and the placement rack 11 in the working area, and then place the oil pipe that needs to be cut and processed on the placement rack 11 and the top of the workbench 1, and align the cutting knife of the pipe saw machine body 12 with the middle of the oil pipe. After turning on the switch of the pipe saw machine body 12, the pipe saw machine body 12 moves downward as a whole, and the middle of the oil pipe is cut at the same time. By arranging a connecting plate 13 at the end of the pipe saw machine body 12, the connecting plate 13 is driven to move during the downward movement of the pipe saw machine body 12 as a whole, and the two groups of The first baffle plate 14 and the second baffle plate 15 will clamp the middle part of the oil pipe at one end to be cut in the middle part of the first baffle plate 14 and the second baffle plate 15, so that after the two sets of second baffle plates 15 contact the top of the workbench 1, the second baffle plate 15 will slide in the middle part of the first baffle plate 14 under the action of the overall downward pressure of the connecting plate 13, and at the same time, the plurality of first springs 17 will be squeezed and deformed during the sliding process until the pipe saw machine body 12 completes the cutting of the oil pipe and the pipe saw machine body 12 moves upward and resets as a whole, and then the second baffle plate 15 is deformed again by utilizing gravity and the reaction force of the first spring 17 after the reset. The baffle 15 slides downward in the middle of the first baffle 14. In this step, the two groups of first baffles 14 are used to limit the position of the cut oil pipe, which can reduce the problem of the oil pipe at one end being cut gradually becoming smaller under the action of the rotation and cutting of the pipe saw machine body 12, causing the cut oil pipe to be tilted in the placement position and resulting in an uneven cutting surface. The performance of the oil pipe after processing is improved, and the need for frequent grinding of the cut surface in the later stage is reduced. In conjunction with the first spring 17 with elastic force, the problem of the second baffle 15 being difficult to reset in the middle of the first baffle 14 can be reduced.

[0025] like Figure 1-5As shown, the middle part of the connecting plate 13 is rotatably connected with a rotating shaft 2; a handle 21 is fixedly connected to the top of the rotating shaft 2; a tooth block 22 is fixedly connected to the middle part of the handle 21; the tooth block 22 is rotatably arranged in the middle part of the connecting plate 13; two sets of racks 23 are slidably connected to the middle part of the connecting plate 13; the two sets of racks 23 and the tooth block 22 are meshed with each other; a latch 24 is slidably connected to the middle part of the handle 21; a plurality of slots 25 matching the shape of the latch 24 are provided on the top of the connecting plate 13; during operation, by providing a rotatable rotating shaft 2 in the middle part of the connecting plate 13, when it is necessary to adjust the spacing between the two sets of first baffles 14, the staff can clamp their hands inside the handle 21, and at the same time, they need to pull the latch 24 upward as a whole, so that the latch 24 slides in the middle part of the handle 21 and its end is separated from the inner wall of the slot 25. At this time The handle 21 can be rotated to make the tooth block 22 rotate inside the connecting plate 13. Because the tooth block 22 and the two sets of racks 23 are meshed with each other, the racks 23 will simultaneously expand or retract to both sides of the connecting plate 13, thereby adjusting the spacing between the two sets of first baffles 14. After the adjustment work is completed, the handle 21 can be loosened, and the downward gravity of the bayonet 24 can be used to clamp its end again in the slot 25, thereby fixing the overall position of the shaft 2. This step cooperates with the rotating shaft 2 rotating in the middle of the connecting plate 13 to improve the flexibility of the two sets of first baffles 14 when working, and reduce the problem that the two fixed first baffles 14 are difficult to clamp and limit the cut oil pipes due to different diameters of the cut oil pipes. At the same time, the sliding bayonet 24 can be used to improve the stability of the rotating shaft 2 placed and fixed inside the connecting plate 13.

[0026] like Figure 1-5 As shown, a second spring 3 is fixedly connected to the bottom of the connecting plate 13; a first telescopic rod 31 is fixedly connected to the bottom of the connecting plate 13; the first telescopic rod 31 is arranged inside the second spring 3; a rubber pad 32 is fixedly connected to the bottom of the second spring 3 and the first telescopic rod 31; the middle part of the rubber pad 32 is arranged in an arc shape; during operation, by arranging a rubber pad 32 of soft material at the bottom of the connecting plate 13, when the cut oil pipe is tilted under the action of the pipe saw machine body 12, the middle part of the oil pipe can be pressed down by the arc-shaped rubber pad 32 and the squeezed second spring 3. This step, in conjunction with the rubber pad 32, can further improve the stability of the cut oil pipe when it is placed, reduce the problem of a high tilting amplitude at the end of the oil pipe, and improve the flatness of the cutting surface.

[0027] like Figure 1-5As shown, two groups of slide grooves 4 are opened in the middle of the connecting plate 13; a limiting rod 41 is fixedly connected to the middle of the first baffle 14; the limiting rod 41 is located inside the slide groove 4 and is slidably arranged; during operation, a slidable slide groove 4 is arranged in the middle of the connecting plate 13, so that when the two groups of first baffles 14 are moving, the limiting rods 41 at their ends will slide in the middle of the slide groove 4. This step cooperates with the limiting rod 41 slidably arranged inside the slide groove 4, which can reduce the problem that only the rack 23 is connected in the middle of the first baffle 14, and the overall position of the first baffle 14 is tilted over a long period of time.

[0028] like Figure 1-5 As shown, a counterweight block 5 is fixedly connected to the bottom of the connecting block 16; during operation, by arranging the counterweight block 5 at the bottom of the connecting block 16, when the second baffle plate 15 slides a small distance inside the first baffle plate 14 and the second baffle plate 15 needs to be reset, the second baffle plate 15 can be slid down with the help of the downward gravity of the counterweight block 5. In this step, the counterweight block 5 is used to reduce the sliding range of the second baffle plate 15 in the middle of the first baffle plate 14 to a small extent without squeezing the first spring 17, resulting in the problem that the first spring 17 is difficult to push the second baffle plate 15 to reset.

[0029] like Figure 1-5 As shown, a plurality of second telescopic rods 6 are fixedly connected to the top of the connecting block 16; the top of the second telescopic rod 6 is fixedly connected to the bottom of the first baffle 14; the second telescopic rod 6 is arranged inside the first spring 17; when working, by arranging the second telescopic rod 6 inside the first spring 17, the first spring 17 will move the middle part of the second telescopic rod 6, and this step cooperates with the telescopic movement inside the first spring 17, which can reduce the problem of bending of the middle part of the first spring 17 during frequent squeezing of the first spring 17 due to the long length of the first spring 17.

[0030] like Figure 1-5 As shown, the top of the handle 21 is concave; when working, by setting the handle 21 to be concave, this step, together with the concave surface in the middle of the handle 21, can reduce the problem of slipping between the handle 21 and the hands of the staff due to excessive sweat.

[0031] like Figure 1-5 As shown, a gasket 7 is fixedly connected to the middle of the second baffle 15; the middle of the gasket 7 is arc-shaped; during operation, a gasket 7 made of soft material is arranged in the middle of the second baffle 15, so that the middle of the gasket 7 will contact the surface of the oil pipe. This step cooperates with the gasket 7 to reduce the wear caused by mutual extrusion between the middle of the second baffle 15 and the oil pipe, thereby improving the smoothness of the surface of the oil pipe.

[0032] The working principle is as follows: after the workbench 1 and the placement rack 11 are installed in the work area, the oil pipe to be cut is then placed on the placement rack 11 and the top of the workbench 1, and the cutting knife of the pipe saw machine body 12 is aligned with the middle of the oil pipe. After the switch of the pipe saw machine body 12 is turned on, the pipe saw machine body 12 moves downward as a whole, and the middle of the oil pipe is cut at the same time. A connecting plate 13 is provided at the end of the pipe saw machine body 12, so that the connecting plate 13 is driven to move during the downward movement of the pipe saw machine body 12 as a whole, and at the same time, the two sets of first baffles 14 and second baffles 15 are cooperated to clamp the middle of the oil pipe at one end to be cut in the middle of the first baffle 14 and the second baffle 15, so that the two sets of second baffles 15 After contacting the top of the workbench 1, the second baffle 15 will slide in the middle of the first baffle 14 under the action of the overall downward pressure of the connecting plate 13, and multiple first springs 17 will be squeezed and deformed during the sliding process until the pipe saw machine body 12 completes the cutting of the oil pipe. After the pipe saw machine body 12 moves upward and resets as a whole, gravity and the reaction force of the first spring 17 after the reset are utilized to make the second baffle 15 slide downward in the middle of the first baffle 14 again. By providing a rotatable shaft 2 in the middle of the connecting plate 13, when it is necessary to adjust the distance between the two groups of first baffles 14, the staff can clamp their hands inside the handle 21 and pull the bayonet 24 upward as a whole to make the bayonet 24 slide downward. The pin 24 slides in the middle of the handle 21 and its end is separated from the inner wall of the slot 25. At this time, the handle 21 can be rotated to make the tooth block 22 rotate inside the connecting plate 13. Because the tooth block 22 and the two sets of racks 23 are meshed with each other, the racks 23 will be synchronously expanded or retracted to both sides of the connecting plate 13, thereby adjusting the distance between the two sets of first baffles 14. After the adjustment is completed, the handle 21 can be loosened, and the end of the pin 24 can be clamped in the slot 25 again by the downward gravity of the pin 24, thereby fixing the overall position of the rotating shaft 2. By arranging a rubber pad 32 of soft material at the bottom of the connecting plate 13, when the cut oil pipe is tilted under the action of the pipe saw machine body 12, the matching The arc-shaped rubber pad 32 and the squeezed second spring 3 can press the middle part of the oil pipe downward. A slidable groove 4 is provided in the middle part of the connecting plate 13, so that when the two groups of first baffles 14 move, the limit rods 41 at their ends will slide in the middle of the groove 4. A counterweight block 5 is provided at the bottom of the connecting block 16, so that when the sliding distance of the second baffle 15 inside the first baffle 14 is small and the second baffle 15 needs to be reset, the second baffle 15 can be slid down by cooperating with the downward gravity of the counterweight block 5. A second telescopic rod 6 is provided inside the first spring 17, so that the first spring 17 will move the middle part of the second telescopic rod 6, and the handle 21 is set to a concave shape.
