Description

Technical Field

[0001] This invention belongs to the field of electrofusion tube processing technology, and specifically relates to an electrofusion tube wiring device. Background Technology

[0002] Electrofusion fittings typically refer to pipe fittings made of PE material that can be melted by the temperature generated by an electric current to connect with other pipes. Electrofusion fittings are usually injection molded. To facilitate subsequent heating and melting of the electrofusion fitting to connect with other pipes, a wire-insertion process is required after manufacturing the fitting. This involves cutting the injection-molded pipe blank to the required dimensions, carving spiral grooves on the inner surface of the fitting, and then embedding heating wires into the grooves to facilitate connection with other pipes.

[0003] Current wiring devices use clamps to hold the pipe fittings, then insert the cutting tool and wiring machine into the pipe fittings one after the other, and then rotate the clamps to rotate the pipe fittings, thereby completing the trenching and wiring work. The existing technology has the following shortcomings: The electrofusion fitting is rotated by rotating the clamp, which requires the clamp to apply a large clamping force to the electrofusion fitting. This can easily cause deformation of the core of the electrofusion fitting, seriously affecting the processing quality of the electrofusion fitting. Summary of the Invention

[0004] In view of this, the present invention provides an electrofusion tube wiring device to solve the problem in the prior art that the electrofusion tube is rotated by rotating the clamp, which requires the clamp to apply a large clamping force to the electrofusion tube, which easily causes the core of the electrofusion tube to deform and seriously affects the processing quality of the electrofusion tube.

[0005] The technical solution adopted in this invention is as follows: An electrofusion tube wiring device includes a machine tool frame, on which a clamp and a mounting table are provided. A turntable and a motor for driving the turntable to rotate are provided on one side of the mounting table. A wiring frame and a tool holder are symmetrically arranged on the turntable. The machine tool frame is also provided with a moving device for driving the mounting table to move along the length direction of the machine tool frame. The clamp is located on one side of the mounting table and is used to clamp the tube.

[0006] In this technical solution, it should be noted that the wiring rack is equipped with a wiring device, and the cutter head is equipped with a cutter head. The wiring structure and cutter head structure are existing technologies; that is, the wiring rack has through holes for the resistance wire to pass through, and the resistance wire is wound on an external take-up reel. In this solution, when wiring the conduit, the conduit is first clamped and fixed using a clamp. Then, a moving device drives the mounting platform towards the conduit, causing the cutter head and wiring rack to extend into the conduit. Next, the position of the cutter head on the cutter head is adjusted so that the cutter head inserts into the inner wall of the conduit. Then, the motor is started, and the moving device drives the mounting platform to continue moving towards the side closer to the conduit. While the mounting platform moves, the motor drives the cutter head on the turntable to rotate, thereby creating a spiral cutter on the inner wall of the conduit. After the groove is dug, the motor is turned off, and the mounting platform is moved in the opposite direction by the moving device, so that the wiring frame moves to the initial position of the spiral groove. Then, the resistance wire on the outer wire wheel is passed through the pass on the wiring frame and fixedly connected to a motor inside the pipe. Then, the moving device and motor are started again, so that the motor drives the wiring frame to rotate during the movement of the mounting platform, thereby laying the resistance wire in the groove and completing the wiring. In summary, in this invention, the pipe is wired by rotating the cutting tool and the wiring device, while the clamping device only needs to play a clamping role. Its clamping force on the pipe is smaller than the force of the clamp driving the pipe to rotate, which makes it less likely to deform the core of the electrofusion pipe and improves the processing quality of the pipe.

[0007] Preferably, the turntable is provided with a vertical rail, the end of the vertical rail is provided with a sliding groove, and both the wiring rack and the knife holder are provided with sliders that are slidably embedded in the sliding groove. The sliding groove is provided with a driving device for driving the two sliders to move closer or further apart.

[0008] In this technical solution, it should be noted that the distance between the wiring rack and the tool holder can be adjusted by the set drive device, so that the wiring rack and the tool holder can adapt to pipes of different diameters.

[0009] Preferably, the driving device includes a guide rod, the two ends of which are rotatably connected to the two ends of the slide groove. The guide rod is provided with two external threads spaced apart and arranged in opposite directions. The two sliders are respectively threadedly connected to the guide rod through the two external threads.

[0010] In this technical solution, it should be noted that, since there are two opposite external threads, simply rotating the guide rod can make the two sliders move closer or further apart, thereby achieving the purpose of adjusting the distance between the wiring rack and the tool holder.

[0011] Preferably, a scale is provided on one side of the vertical rail, and the scale is set vertically.

[0012] In this technical solution, it should be noted that the staff can observe the adjustment distance between the knife holder and the wiring rack through the set scale, which makes it convenient for the staff to adjust in real time according to the diameter of the pipe fitting.

[0013] Preferably, a buffer support structure is provided between the cabling rack and the tool holder. The buffer support structure includes a fixed cylinder and a telescopic cylinder. One end of the telescopic cylinder is slidably inserted into the fixed cylinder. One end of the fixed cylinder is connected to the cabling rack. One end of the telescopic cylinder is connected to the tool holder. An elastic element is provided inside the fixed cylinder. The telescopic cylinder is connected to the elastic element.

[0014] In this technical solution, it should be noted that during the trenching and cabling process, the cabling rack and tool holder are easily deformed due to the pressure from the inner wall of the pipe. Based on this, this solution is equipped with a buffer support structure. When the tool holder or cabling rack is subjected to pressure, it will be supported and buffered by elastic elements, thereby improving the service life of the cabling rack and tool holder.

[0015] Preferably, the moving device includes a lead screw, which is rotatably connected to one side of the machine tool frame. A connecting frame is provided on one side of the mounting table, and the connecting frame is threadedly connected to the lead screw. The lead screw is driven by an electric motor.

[0016] In this technical solution, it should be noted that the rotation of the lead screw drives the connecting frame to move, which in turn drives the mounting table connected to the connecting frame to move along the length of the machine tool frame.

[0017] Preferably, a fixed seat is provided on one side of the machine tool frame; the fixture includes a fixed clamping plate, a fixed shaft is provided on the fixed clamping plate, the fixed shaft is fixedly connected to the fixed seat, a support plate is provided between the fixed clamping plate and the fixed seat, the support plate is slidably connected to the fixed shaft, the support plate is connected to the end of a cylinder provided on the fixed seat, and a plurality of connecting columns are provided on the support plate, the plurality of connecting columns slidingly passing through the fixed clamping plate and fixedly connected to a movable clamping plate. A cylindrical structure is formed between the fixed clamping plate, the connecting columns and the movable clamping plate, and an inlet for pipe fittings to pass through is provided at the top of the cylindrical structure.

[0018] In this technical solution, it should be noted that when it is necessary to clamp the pipe fitting, the pipe fitting is lifted to the top of the inlet by the lifting device, and then the pipe fitting is placed between the fixed clamp and the movable clamp from the inlet by the lifting device. Then the cylinder is activated, and the cylinder drives the support plate to move. The support plate drives the movable clamp to move closer to the fixed clamp through the transmission of the connecting column, and finally clamps the pipe fitting.

[0019] Preferably, the top of the machine tool frame is slidably connected to a support slide for supporting the movable clamping plate. A pulley is rotatably connected to the top of the support slide, and a groove is provided on the side wall of the pulley. An annular plate is provided on the side wall of the movable clamping plate, with both sides of the annular plate located within the groove.

[0020] In this technical solution, it should be noted that by using a support slide to support the moving clamp, the weight of the moving clamp is not entirely distributed on the cylinder, thus improving the cylinder's lifespan.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the pipe fitting is wired by rotating the cutting tool and the wiring device, while the clamping device only needs to perform the function of clamping. Its clamping force on the pipe fitting is smaller than the force of the clamp driving the pipe fitting to rotate, which makes it less likely to deform the core of the electrofusion pipe fitting and improves the processing quality of the pipe fitting. 2. In this invention, the distance between the wiring rack and the tool holder can be adjusted by the driving device, so that the wiring rack and the tool holder can adapt to pipes of different diameters; 3. In this invention, the operator can observe the adjustment distance between the knife holder and the wiring rack through the set scale, which makes it convenient for the operator to adjust in real time according to the diameter of the pipe fitting; 4. In this invention, when the tool holder or cabling rack is subjected to pressure, it will be supported and buffered by elastic elements, thereby improving the lifespan of the cabling rack and tool holder; 5. In this invention, a supporting slide is provided to support the moving clamping plate, so that the weight of the moving clamping plate is not entirely distributed on the cylinder, thereby improving the cylinder's lifespan.

[0031] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses an electrofusion tube wiring device, including a machine tool frame 10. The machine tool frame 10 is provided with a clamp 20 and a mounting table 30. A turntable 32 and a motor 31 for driving the turntable 32 to rotate are provided on one side of the mounting table 30. A wiring frame 34 and a tool holder 33 are symmetrically provided on the turntable 32. The machine tool frame 10 is also provided with a moving device for driving the mounting table 30 to move along the length direction of the machine tool frame 10. The clamp 20 is located on one side of the mounting table 30 and is used to clamp the tube. It should be noted that the wiring rack 34 is equipped with a wiring device, and the cutter head is provided on the cutter holder 33. The wiring structure and cutter head structure are existing technologies; that is, the wiring rack 34 has through holes for the resistance wire to pass through, and the resistance wire is wound on an external take-up reel. In this solution, when wiring the conduit, the conduit is first clamped and fixed by the clamp 20. Then, the moving device drives the mounting platform 30 to move towards the conduit, causing the cutter holder 33 and the wiring rack 34 to extend into the conduit. Next, the position of the cutter head on the cutter holder 33 is adjusted so that the cutter head inserts into the inner wall of the conduit. Then, the motor 31 is started, and the moving device drives the mounting platform 30 to continue moving towards the side closer to the conduit. While the mounting platform 30 moves, the motor 31 drives the cutter holder 33 on the turntable 32 to rotate, thereby carving a spiral pattern on the inner wall of the conduit. After the cutting groove is dug, the motor 31 is turned off, and the mounting platform 30 is moved in the opposite direction by the moving device, so that the wiring frame 34 moves to the initial position of the spiral cutting groove. Then, the resistance wire on the outer wire wheel is passed through the pass on the wiring frame 34 and fixedly connected to a motor 31 inside the pipe. Then, the moving device and the motor 31 are started again, so that the mounting platform 30 moves while the motor 31 drives the wiring frame 34 to rotate, thereby laying the resistance wire in the cutting groove and completing the wiring. In summary, in this invention, the pipe is wired by rotating the cutting tool and the wiring device, while the clamping device only needs to play a clamping role. Its clamping force on the pipe is smaller than the force of the clamp 20 driving the pipe to rotate, which makes it less likely to deform the core of the electrofusion pipe and improves the processing quality of the pipe. Example 2

[0032] like Figures 2-4As shown, this embodiment is largely the same as the above embodiment, except that the turntable 32 is provided with a vertical rail 35, the end of the vertical rail 35 is provided with a sliding groove 352, and both the wiring rack 34 and the tool holder 33 are provided with sliders 341 that are slidably embedded in the sliding groove 352. The sliding groove 352 is provided with a driving device for driving the two sliders 341 to move closer or further apart. It should be noted that the driving device can adjust the distance between the wiring rack 34 and the tool holder 33, thereby allowing the wiring rack 34 and the tool holder 33 to adapt to pipes of different diameters.

[0033] like Figures 2-3 As shown, in this embodiment, the driving device includes a guide rod 353, the two ends of which are rotatably connected to the two ends of the slide groove 352. Two external threads 354 are spaced apart on the guide rod 353 and are arranged in opposite directions. Two sliders 341 are threadedly connected to the guide rod 353 via the two external threads 354. It should be noted that because there are two opposite external threads 354, simply rotating the guide rod 353 can move the two sliders 341 closer together or further apart, thereby adjusting the distance between the wiring rack 34 and the tool holder 33.

[0034] like Figure 2 As shown, in this embodiment, a scale 351 is provided on one side of the vertical rail 35, and the scale 351 is vertically arranged. It should be noted that the operator can observe the adjustment distance between the knife holder 33 and the wiring rack 34 through the scale 351, which facilitates the operator to adjust in real time according to the diameter of the pipe fitting.

[0035] like Figure 3 As shown, in this embodiment, a buffer support structure 36 is provided between the cabling rack 34 and the tool holder 33. The buffer support structure 36 includes a fixed cylinder 362 and a telescopic cylinder 361. One end of the telescopic cylinder 361 is slidably inserted into the fixed cylinder 362. One end of the fixed cylinder 362 is connected to the cabling rack 34, and one end of the telescopic cylinder 361 is connected to the tool holder 33. An elastic element 363 is provided inside the fixed cylinder 362, and the telescopic cylinder 361 is connected to the elastic element 363. It should be noted that during the trenching and cabling process, the cabling rack 34 and the tool holder 33 are easily deformed due to the pressure from the inner wall of the pipe. Based on this, this solution provides a buffer support structure 36. When the tool holder 33 or the cabling rack 34 is subjected to pressure, it will be supported and buffered by the elastic element 363, thereby improving the service life of the cabling rack 34 and the tool holder 33. Example 3

[0036] like Figure 1As shown, this embodiment is largely the same as the above embodiment, except that the moving device includes a lead screw 41, which is rotatably connected to one side of the machine tool frame 10. A connecting frame 40 is provided on one side of the mounting table 30, and the connecting frame 40 is threadedly connected to the lead screw 41. The lead screw 41 is driven by a motor 42. It should be noted that in this solution, the rotation of the lead screw 41 drives the connecting frame 40 to move, thereby causing the mounting table 30 connected to the connecting frame 40 to move along the length of the machine tool frame 10. Example 4

[0037] like Figure 1 and Figure 5 As shown, this embodiment is largely the same as the above embodiment, except that a fixed seat 28 is provided on one side of the machine tool frame 10; the clamp 20 includes a fixed clamping plate 21, a fixed shaft 22 is provided on the fixed clamping plate 21, the fixed shaft 22 is fixedly connected to the fixed seat 28, a support plate 26 is provided between the fixed clamping plate 21 and the fixed seat 28, the support plate 26 is slidably connected to the fixed shaft 22, the support plate 26 is connected to the end of the cylinder 27 provided on the fixed seat 28, and a plurality of connecting posts 24 are provided on the support plate 26, the plurality of connecting posts 24 slide through the fixed clamping plate 21 and are fixedly connected to the movable clamping plate 23. A cylindrical structure is formed between the fixed clamping plate 21, the connecting posts 24 and the movable clamping plate 23, and an inlet 25 for pipe fittings to pass through is provided at the top of the cylindrical structure. It should be noted that when it is necessary to clamp the pipe fitting, the pipe fitting is lifted to above the inlet 25 by the lifting device, and then the pipe fitting is placed between the fixed clamping plate 21 and the movable clamping plate 23 from the inlet 25 by the lifting device. Then, the cylinder 27 is activated, and the cylinder 27 drives the support plate 26 to move. The support plate 26 drives the movable clamping plate 23 to move closer to the fixed clamping plate 21 through the transmission of the connecting column 24, and finally clamps the pipe fitting.

[0038] like Figure 5 As shown, in this embodiment, the top of the machine tool frame 10 is slidably connected to a support slide 231 for supporting the movable clamping plate 23. A pulley 232 is rotatably connected to the top of the support slide 231. A groove 233 is provided on the side wall of the pulley 232, and an annular plate 234 is provided on the side wall of the movable clamping plate 23. Both sides of the annular plate 234 are located within the groove 233. It should be noted that by using the support slide 231 to support the movable clamping plate 23, the weight of the movable clamping plate 23 is not entirely distributed on the cylinder 27, thus improving the lifespan of the cylinder 27.

[0039] The working principle of this invention is as follows: When wiring is required for the pipe fitting, the pipe fitting is first hoisted above the inlet 25 using a lifting device. Then, the pipe fitting is placed between the fixed clamp 21 and the movable clamp 23 from the inlet 25 using the lifting device. Next, the cylinder 27 is activated, which drives the support plate 26 to move. The support plate 26, through the transmission of the connecting column 24, drives the movable clamp 23 to move closer to the fixed clamp 21, finally clamping the pipe fitting. After that, the motor 42 is activated, which drives the lead screw 41 to rotate, thereby moving the mounting platform 30 towards the pipe fitting, so that the tool holder 33 and the wiring frame 34 extend into the pipe fitting. Then, the guide rod 353 is rotated to adjust the distance between the tool holder 33 and the wiring frame 34 according to the diameter of the pipe fitting. Finally, the position of the blade on the tool holder 33 is adjusted so that the blade inserts into the pipe fitting. The inner wall of the pipe fitting is then moved. Motors 31 and 42 are started, and the mounting platform 30 continues to move towards the side closest to the pipe fitting. Simultaneously, motor 31 drives the knife holder 33 on the turntable 32 to rotate, thus creating a spiral groove on the inner wall of the pipe fitting. After the groove is created, motor 31 is turned off, and the mounting platform 30 is moved in the opposite direction via the motor and lead screw 41, causing the wiring rack 34 to move to the initial position of the spiral groove. Then, the resistance wire on the outer reel is passed through the wiring rack 34 and fixedly connected to a motor 31 inside the pipe fitting. Then, motors 42 and 31 are started again, causing motor 31 to simultaneously drive the wiring rack 34 to rotate during the movement of the mounting platform 30, thereby laying the resistance wire in the groove and completing the wiring.
