Description

Technical Field

[0001] The invention relates to the technical field of tapping processing, and in particular to an automatic material removal device for pipeline tapping. Background Art

[0002] Tapping refers to using a certain torque to screw the tap into the bottom hole to be drilled to produce an internal thread. Threaded connection is a common and secure connection method in modern times. Various metal pipes can be securely and tightly connected through threads.

[0003] During the process of tapping a pipe, debris will be generated. Part of the debris will be pushed out of the pipe due to the rotation of the screw during the tapping process, while part of the debris will remain on the inner wall of the pipe. Since the pipe may be used to transport liquids and gases, if the inner wall of the pipe is not well cleaned, the pipe will be contaminated during transportation due to the debris on the inner wall. Therefore, the present invention designs an automatic material removal device for pipe tapping to solve the above problem. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a pipeline tapping automatic material removal device, comprising a material removal box, the inner wall of the material removal box is fixedly connected with a slide rail, and the upper surface of the material removal box is fixedly connected with a fixing frame;

[0005] The material removal equipment also has:

[0006] A lubrication mechanism, the lubrication mechanism includes a support sleeve, the inner wall of the support sleeve is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a tapping chuck, the outer surface of the tapping chuck is sleeved with a lubrication box, the inner wall of the lubrication box is fixedly connected to a plug, and the side of the lubrication box away from the servo motor is fixedly connected to a lubrication pipe; the electric slide rail can drive the servo motor, the tapping chuck and the lubrication box to move toward one side of the pipeline, and when the tapping chuck gradually approaches the pipeline, starting the servo motor can drive the tapping chuck and the lubrication box to rotate through the output shaft, and at this time, the intelligent valve inside the lubrication box is opened, allowing the lubricating oil inside the lubrication box to enter the inside of the lubrication pipe.

[0007] The clamping mechanism includes a pipeline, the inner wall of the pipeline is slidably connected with a flushing pipe, the outer surface of the flushing pipe is fixedly connected with a baffle, both sides of the flushing pipe are fixedly connected with water pipes, the top of the flushing pipe is fixedly connected with a clamping ring, the inner wall of the clamping ring is fixedly connected with a sleeve, the inner wall of the sleeve is fixedly connected with a telescopic rod, and the output end of the telescopic rod is fixedly connected with a sponge block.

[0008] Furthermore, the lower surface of the support sleeve is fixedly connected to the upper surface of the slide rail, the outer surface of the tapping chuck is fixedly connected to the inner wall of the lubrication box, both sides of the clamping ring are fixedly connected to the side of the fixed frame away from the removal box, the pipe is arranged at the center of the clamping ring, and the upper surface of the clamping mechanism is fixedly connected with a protective component. The pipe to be tapped can be inserted horizontally into the outer surface of the flushing pipe, and the rear end face of the pipe is against the outer surface of the baffle to achieve initial support for the pipe. The extension of the telescopic rod inside the sleeve can drive the sponge block to move closer to the side of the pipe, and finally the pipe is fixed by three sponge blocks.

[0009] Furthermore, the protective component includes a three-phase motor, the outer surface of the three-phase motor is fixedly connected to a support seat, the outer surface of the three-phase motor output shaft is rotatably connected to a support plate, the outer surface of the three-phase motor output shaft is fixedly connected to a bent plate, the lower surface of the bent plate is fixedly connected to a fixed sleeve, the inner wall of the fixed sleeve is fixedly connected to an electric rod, the inner wall of the protective component is fixedly connected to a scraping component, and the outer surface of the protective component is fixedly connected to a flushing component.

[0010] Furthermore, a protective plate is fixedly connected to one end of the electric rod away from the fixing sleeve, an oil bag is fixedly connected to the side of the protective plate close to the electric rod, an inclined block is slidably connected to the lower surface of the protective plate, and a shield is slidably connected to the upper surface of the protective plate.

[0011] Furthermore, the lower surface of the support plate is fixedly connected to the upper surface of the clamping ring, the outer surface of the inclined block is fixedly connected to the inner wall of the shield, and the side of the shield close to the oil bag is fixedly connected to the end of the bending rod away from the output shaft of the three-phase motor. The upper three-phase motor starts and drives the bending plate, the fixed sleeve and the electric rod to rotate downward through the output shaft until the side of the bending plate close to the scraping component rotates to a horizontal position, and the output shaft of the three-phase motor stops rotating. Since the bent plate in the horizontal position is still a certain distance from the pipe below, the fixed sleeve will not touch the pipe. In the process of the bent plate gradually rotating downward, the electric rod starts and contracts, which can drive the protective plate to slide on the inner wall of the inclined block toward the side close to the oil bag.

[0012] Furthermore, the scraping component includes a limiting shaft, a scraper is slidably connected to the outer surface of the limiting shaft, a compression spring is fixedly connected to the side of the scraper away from the electric rod, a pull rope is fixedly connected to the side of the scraper close to the compression spring, and a guide tube is slidably connected to the outer surface of the pull rope.

[0013] Furthermore, the outer surface of the limit shaft is fixedly connected to the inner wall of the baffle, the upper surface of the scraper is slidably connected to the lower surface of the baffle, the end of the extrusion spring away from the scraper is fixedly connected to the inner wall of the baffle, and the end of the guide tube close to the protective plate is fixedly connected to the outer surface of the inclined block. When the electric rod contracts and drives the protective plate to move, the protective plate can pull the scraper along the surface of the limit shaft through the pull ropes on the left and right sides, and the extrusion spring will be squeezed to a certain extent during the movement of the scraper. The guide tube provides support and guidance for the movement of the pull rope. The final position of the scraper is close to the side of the guide tube. In the process of the protective plate gradually approaching the guide tube, the scraper cannot feel the pulling force of the pull rope, so the scraper will reset along the surface of the limit shaft under the squeezing of the extrusion spring. The scraper will move in close contact with the lower surface of the baffle during the movement, and scrape off the lubricating oil attached to the surface of the baffle and the tapping debris inside the lubricating oil.

[0014] Furthermore, the flushing component includes a water tank, the inner wall of the water tank is fixedly connected to a tension spring, the end of the tension spring away from the water tank is fixedly connected to a slide, the outer surface of the slide is provided with a circular groove, the side of the slide away from the tension spring is fixedly connected to a pull rope, and the outer surface of the pull rope is slidably connected to a limiting tube.

[0015] Furthermore, the bottom of the water tank is fixedly connected to the top of the water pipe, the lower surface of the slide is slidably connected to the bottom of the inner wall of the water tank, the end of the pull rope away from the slide is fixedly connected to the outer surface of the bent plate, and the end of the limit tube close to the slide is fixedly connected to the outer surface of the water tank. The three-phase motor rotates a certain angle through the output shaft again, that is, it can drive the bent plate to rotate a certain angle toward one side of the water tank. The bent plate will approach the limit tube during the rotation process, and the slide cannot feel the tension of the pull rope, so it will slide toward the side away from the limit tube under the tension of the tension spring. During the sliding process, the circular groove will gradually slide to the top of the water pipe, that is, the gap between the slide and the water pipe is opened, and the water inside the water tank will flow into the inside of the water pipe through the circular groove, and enter the inside of the flushing pipe through the water pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) After the pipe is tapped, the device can move the slide plate so that the slide groove on the surface of the slide plate moves to the top of the water pipe, thereby opening the gap between the slide plate and the water pipe, so that the water inside the water tank can enter the water pipe and the flushing pipe through the gap, and the inner wall of the pipe can be flushed, thereby avoiding the problem of damage to the pipe due to heat from tapping. At the same time, the cleaning effect of the device on the inner wall of the pipe can also avoid the problem of contamination of the pipe due to debris on the inner wall during transportation.

[0018] (2) The surface of the tapping chuck is provided with a lubrication box and a lubrication tube. The oil outlet end of the lubrication tube is provided in the depression of the tapping head. At the same time, the oil outlet hole provided on the surface of the lubrication tube is aligned with the surface of the tapping head, so as to prevent the lubrication tube from dropping the lubrication oil to the outside during the rotation process, thereby causing the waste of lubrication oil. The device has a lubricating effect on the tapping chuck, which can prevent the tapping chuck from being damaged due to high temperature during the process of tapping the pipe, and can also prevent the tapping chuck from getting stuck due to the tapping resistance of the pipe.

[0019] (3) When the tapping chuck is tapping the pipe, the shielding plates on the upper and lower sides of the pipe can fit together to surround the outside of the tapping chuck. The shielding effect can prevent the lubricating oil and debris attached to the surface of the tapping chuck from being thrown to the outside due to the centrifugal force during rotation.

[0020] (4) When the shield is reset on one side of the pipe, the device can move the protective plate to further block the gap between the shield and the bottom, which can prevent the lubricating oil on the surface of the shield from falling to the upper surface of the pipe below under the action of gravity, thereby polluting the outer surface of the pipe. At the same time, the movement of the scraper by the device can scrape off the lubricating oil and debris attached to the inner wall of the shield, thereby preventing the lubricating oil from falling to the surface of the tapping chuck due to the lubricating oil and debris attached to the inner wall of the shield when it is used next time, further avoiding the problem of affecting the subsequent use of the tapping chuck.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0033] For the first embodiment, please refer to Figure 1-Figure 6 The present invention is an automatic material removal device for pipe tapping, comprising a material removal box 1, a slide rail 2 is fixedly connected to the inner wall of the material removal box 1, and a fixing frame 3 is fixedly connected to the upper surface of the material removal box 1;

[0034] The material removal equipment also has:

[0035] The lubrication mechanism 4 includes a support sleeve 41, the inner wall of the support sleeve 41 is fixedly connected to a servo motor 42, the output end of the servo motor 42 is fixedly connected to a tapping chuck 43, the outer surface of the tapping chuck 43 is sleeved with a lubrication box 44, the inner wall of the lubrication box 44 is fixedly connected to a plug 45, and a lubrication pipe 46 is fixedly connected to the side of the lubrication box 44 away from the servo motor 42;

[0036] The clamping mechanism 5 includes a pipe 51, the inner wall of the pipe 51 is slidably connected with a flushing pipe 52, the outer surface of the flushing pipe 52 is fixedly connected with a baffle 53, both sides of the flushing pipe 52 are fixedly connected with water pipes 54, the top of the flushing pipe 52 is fixedly connected with a clamping ring 55, the inner wall of the clamping ring 55 is fixedly connected with a sleeve 56, the inner wall of the sleeve 56 is fixedly connected with a telescopic rod 57, and the output end of the telescopic rod 57 is fixedly connected with a sponge block 58.

[0037] The lower surface of the support sleeve 41 is fixedly connected to the upper surface of the slide rail 2, the outer surface of the tapping chuck 43 is fixedly connected to the inner wall of the lubrication box 44, both sides of the clamping ring 55 are fixedly connected to the side of the fixed frame 3 away from the removal box 1, the pipe 51 is arranged at the center of the clamping ring 55, and the upper surface of the clamping mechanism 5 is fixedly connected with a protective component 6.

[0038] First, the worker inserts the pipe 51 to be tapped transversely into the outer surface of the flushing pipe 52. Figure 5 and Figure 6 The rear end face of the pipe 51 abuts against the outer surface of the baffle 53 to provide preliminary support for the pipe 51. The telescopic rod 57 inside the sleeve 56 extends, which can drive the sponge block 58 to move closer to the pipe 51, and finally the pipe 51 is fixed by the three sponge blocks 58. After fixing the pipeline 51, the slide rail 2 can drive the servo motor 42, the tapping chuck 43, and the lubrication box 44 to move toward one side of the pipeline 51. When the tapping chuck 43 gradually approaches the pipeline 51, the servo motor 42 is started to drive the tapping chuck 43 and the lubrication box 44 to rotate through the output shaft. At this time, the intelligent valve inside the lubrication box 44 is opened, so that the lubricating oil inside the lubrication box 44 can enter the inside of the lubrication pipe 46. The surface of the lubrication pipe 46 is provided with a plurality of filter holes, and the filter holes are all oriented toward the surface of the tapping chuck 43. Therefore, under the rotation of the lubrication box 44 and the lubrication pipe 46, the lubricating oil can be thrown onto the surface of the tapping chuck 43 without being thrown to the outside, so as to achieve the lubrication effect on the tapping chuck 43. When a certain amount of lubricating oil is released, the intelligent valve controls the valve to close, and the lubricating oil cannot enter the lubrication pipe 46. At the same time, the tapping chuck 43 can tap the pipe 51 during rotation. Since the lubricating tube 46 is arranged at the groove of the tapping head, the rotation of the lubricating tube 46 will not affect the tapping operation.

[0039] For the second embodiment, please refer to Figure 1-Figure 10The present invention is an automatic material removal device for tapping a pipe 51. The protective component 6 includes a three-phase motor 61. The outer surface of the three-phase motor 61 is fixedly connected to a support seat 62. The outer surface of the output shaft of the three-phase motor 61 is rotatably connected to a support plate 63. The outer surface of the output shaft of the three-phase motor 61 is fixedly connected to a bent plate 64. The lower surface of the bent plate 64 is fixedly connected to a fixed sleeve 65. The inner wall of the fixed sleeve 65 is fixedly connected to an electric rod 66. The inner wall of the protective component 6 is fixedly connected to a scraping component 7. The outer surface of the protective component 6 is fixedly connected to a flushing component 8.

[0040] A protective plate 67 is fixedly connected to one end of the electric rod 66 away from the fixed sleeve 65, an oil bag 68 is fixedly connected to the side of the protective plate 67 close to the electric rod 66, an inclined block 69 is slidably connected to the lower surface of the protective plate 67, and a shielding plate 601 is slidably connected to the upper surface of the protective plate 67.

[0041] The lower surface of the support plate 63 is fixedly connected to the upper surface of the clamping ring 55, the outer surface of the inclined block 69 is fixedly connected to the inner wall of the baffle 601, and the side of the baffle 601 close to the oil bag 68 is fixedly connected to the end of the bending rod away from the output shaft of the three-phase motor 61.

[0042] When in use, before the tapping chuck 43 rotates, the three-phase motor 61 above starts and drives the bent plate 64, the fixed sleeve 65 and the electric rod 66 to rotate downward through the output shaft, until the bent plate 64 rotates to a horizontal position near the scraping component 7, and the output shaft of the three-phase motor 61 stops rotating. Since the bent plate 64 in the horizontal position is still a certain distance from the pipe 51 below, the fixed sleeve 65 will not touch the pipe 51. In the process of the bent plate 64 gradually rotating downward, the electric rod 66 starts and contracts, which can drive the protective plate 67 to slide on the inner wall of the inclined block 69 toward the side close to the oil bag 68, such as Figure 8 As shown, a sliding groove is provided on the inner wall of the inclined block 69. During the sliding process of the protective plate 67, the upper surface of the protective plate 67 also slides with the lower surface of the shield 601. Therefore, when the bent plate 64 is in a horizontal position, the protective plate 67 can slide a certain distance until the gap under the shield 601 is opened, so that the shield 601 can completely face the upper surface of the pipe 51, that is, there is no other object blocking the shield 601 and the pipe 51.

[0043] Therefore, before the tapping chuck 43 rotates, the three-phase motor 61 at the bottom will also make the bent plate 64 gradually approach the upper pipe 51 during rotation, and finally drive the shield plates 601 on the upper and lower sides of the pipe 51 to fit together under the rotation of the bent plate 64. The lubricated tapping chuck 43 may throw the lubricating oil on the surface of the tapping chuck 43 to the outside during rotation. Therefore, it is necessary to set shield plates 601 on the upper and lower sides of the pipe 51 for protection, which can block the thrown lubricating oil and prevent the lubricating oil from falling to the outside. The shield plates 601 on the upper and lower sides are larger than the tapping chuck 43 and the pipe 51, and will not affect the operation of the tapping chuck 43 on the pipe 51. At the same time, part of the waste produced by the tapping chuck 43 tapping the pipe 51 will be directly pushed out of the pipe 51 due to the rotation of the tapping chuck 43, and then fall to the surface of the shield plate 601 below under the action of gravity.

[0044] After the tapping chuck 43 completes tapping the pipe 51, the servo motor 42 needs to flip and drive the tapping chuck 43 to flip, and the electric slide rail 2 drives the servo motor 42 to move to the side away from the pipe 51. During the reversal of the servo motor 42, the tapping chuck 43 is prone to throw the lubricating oil and some debris attached to the surface to the outside during rotation, so the shielding plates 601 on the upper and lower sides need to surround and shield the tapping chuck 43. After the tapping chuck 43 is completely withdrawn from the inner wall of the pipe 51, the servo motor 42 stops rotating, and the slide rail 2 drives the support sleeve 41, the servo motor 42 and the tapping chuck 43 to move and reset.

[0045] The scraping component 7 includes a limiting shaft 71, and a scraper 72 is slidably connected to the outer surface of the limiting shaft 71. The side of the scraper 72 away from the electric rod 66 is fixedly connected to a compression spring 73, and the side of the scraper 72 close to the compression spring 73 is fixedly connected to a pull rope 74. The outer surface of the pull rope 74 is slidably connected to a guide tube 75.

[0046] The outer surface of the limiting shaft 71 is fixedly connected to the inner wall of the baffle 601, the upper surface of the scraper 72 is slidably connected to the lower surface of the baffle 601, the end of the extrusion spring 73 away from the scraper 72 is fixedly connected to the inner wall of the baffle 601, and the end of the guide tube 75 close to the protective plate 67 is fixedly connected to the outer surface of the inclined block 69.

[0047] When the electric rod 66 contracts and drives the protective plate 67 to move, the protective plate 67 can pull the scraper 72 to move along the surface of the limit shaft 71 through the pull ropes 74 on the left and right sides. During the movement of the scraper 72, the extrusion spring 73 is squeezed to a certain extent. The guide tube 75 provides support and guidance for the movement of the pull rope 74. The final position of the scraper 72 is close to the side of the guide tube 75.

[0048] When the tapping chuck 43 withdraws from the internal space surrounded by the upper and lower shields 601, the three-phase motor 61 reverses and controls the bent plate 64 to rotate toward the side away from the pipe 51 through the output shaft. The electric rod 66 extends and pushes the protective plate 67 to slide along the surface of the inclined block 69 toward the side close to the guide tube 75. The protective plate 67 can close the gap below the shield 601 during the sliding process to prevent the lubricating oil and debris attached to the surface from dripping down during the gradual lifting of the shield 601. When the protective plate 67 gradually approaches the guide tube 75, the scraper 72 cannot feel the pulling force of the pull rope 74, so the scraper 72 will be reset along the surface of the limit shaft 71 under the pressure of the extrusion spring 73. During the movement, the scraper 72 will move in contact with the lower surface of the shield 601 and scrape off the lubricating oil attached to the surface of the shield 601 and the tapping debris inside the lubricating oil. The scraped lubricating oil and debris slide down along the inner wall of the shield 601. At this time, the position of the shield 601 is similar to Figure 7 Therefore, the lubricating oil and the debris will gradually flow into the oil bag 68 at the bottom to collect the lubricating oil and the debris. When the oil bag 68 is full, it can be replaced. A one-way valve is provided inside the oil bag 68, so that the oil and the debris can enter but not easily go out.

[0049] like Figure 4 As shown, the surface of the lower shield 601 is not provided with other parts such as the scraper 72 and the oil bag 68, but only the shield 601 and other curved plates 64 and the three-phase motor 61. Therefore, when the shield 601 gradually moves away from the pipeline 51, that is, when it rotates downward, the larger tapping debris attached to the surface of the shield 601 falls into the interior of the material removal box 1 below under gravity, and at the same time, the lubricating oil and debris on the surface of the shield 601 will slide along the shield 601 into the interior of the material removal box 1 below.

[0050] The flushing component 8 includes a water tank 81, the inner wall of which is fixedly connected to a tension spring 82, the end of the tension spring 82 away from the water tank 81 is fixedly connected to a slide plate 83, the outer surface of the slide plate 83 is provided with a circular groove 84, the side of the slide plate 83 away from the tension spring 82 is fixedly connected to a pull rope 85, and the outer surface of the pull rope 85 is slidably connected to a limiting tube 86.

[0051] The bottom of the water tank 81 is fixedly connected to the top of the water pipe 54, the lower surface of the slide plate 83 is slidably connected to the bottom of the inner wall of the water tank 81, the end of the pull rope 85 away from the slide plate 83 is fixedly connected to the outer surface of the bent plate 64, and the end of the limiting tube 86 close to the slide plate 83 is fixedly connected to the outer surface of the water tank 81.

[0052] During use, after the upper curved plate 64 is reset, the three-phase motor 61 rotates a certain angle again through the output shaft, that is, it can drive the curved plate 64 to rotate a certain angle toward the side of the water tank 81. The curved plate 64 will gradually approach the limit tube 86 during the rotation. The slide plate 83 cannot feel the pulling force of the pull rope 85, so it will slide to the side away from the limit tube 86 under the pulling force of the tension spring 82. During the sliding process, the circular groove 84 will gradually slide to the top of the water pipe 54, that is, the gap between the slide plate 83 and the water pipe 54 is opened. The water inside the water tank 81 will flow into the inside of the water pipe 54 through the circular groove 84, and enter the inside of the flushing pipe 52 through the water pipe 54. The water inside the flushing pipe 52 will flow into the inside of the tapped pipe 51 to flush the debris and part of the lubricating oil inside the pipe 51. After flushing is completed, the three-phase motor 61 drives the curved plate 64 to rotate toward the side away from the limit tube 86 through the output shaft, so that the curved plate 64 returns to the position as shown in the figure. Figure 7 When the bent plate 64 moves away from the limiting tube 86 , the pull rope 85 pulls the slide plate 83 , so that the slide plate 83 slides a certain distance toward the limiting tube 86 , so that the circular groove 84 leaves the top of the water pipe 54 , and blocks the gap between the slide plate 83 and the water pipe 54 .

[0053] The water flowing out from the inside of the pipe 51 will also fall into the inside of the shield 601 below, and the lubricating oil and debris attached to the inside of the shield 601 can be flushed again.

[0054] The staff can take the flushed pipe 51, and the debris and lubricating oil flushed inside the pipe 51 will fall into the removal box 1 below.

[0055] The specific workflow is as follows:

[0056] First, the worker inserts the pipe 51 to be tapped transversely into the outer surface of the flushing pipe 52. Figure 5 and Figure 6The rear end face of the pipe 51 abuts against the outer surface of the baffle 53 to provide preliminary support for the pipe 51. The telescopic rod 57 inside the sleeve 56 extends, which can drive the sponge block 58 to move closer to the pipe 51, and finally the pipe 51 is fixed by the three sponge blocks 58. After fixing the pipeline 51, the slide rail 2 can drive the servo motor 42, the tapping chuck 43, and the lubrication box 44 to move toward one side of the pipeline 51. When the tapping chuck 43 gradually approaches the pipeline 51, the servo motor 42 is started to drive the tapping chuck 43 and the lubrication box 44 to rotate through the output shaft. At this time, the intelligent valve inside the lubrication box 44 is opened, so that the lubricating oil inside the lubrication box 44 can enter the inside of the lubrication pipe 46. The surface of the lubrication pipe 46 is provided with a plurality of filter holes, and the filter holes are all oriented toward the surface of the tapping chuck 43. Therefore, under the rotation of the lubrication box 44 and the lubrication pipe 46, the lubricating oil can be thrown onto the surface of the tapping chuck 43 without being thrown to the outside, so as to achieve the lubrication effect on the tapping chuck 43. When a certain amount of lubricating oil is released, the intelligent valve controls the valve to close, and the lubricating oil cannot enter the lubrication pipe 46. At the same time, the tapping chuck 43 can tap the pipe 51 during rotation. Since the lubricating tube 46 is arranged at the groove of the tapping head, the rotation of the lubricating tube 46 will not affect the tapping operation.

[0057] Before the tapping chuck 43 rotates, the three-phase motor 61 above starts and drives the bent plate 64, the fixed sleeve 65 and the electric rod 66 to rotate downward through the output shaft until the bent plate 64 rotates to a horizontal position near the scraping component 7, and the output shaft of the three-phase motor 61 stops rotating. Since the bent plate 64 in the horizontal position is still a certain distance away from the pipe 51 below, the fixed sleeve 65 will not touch the pipe 51. As the bent plate 64 gradually rotates downward, the electric rod 66 starts and contracts, which can drive the protective plate 67 to slide on the inner wall of the inclined block 69 toward the side close to the oil bag 68, as shown in FIG. Figure 8 As shown, a sliding groove is provided on the inner wall of the inclined block 69. During the sliding process of the protective plate 67, the upper surface of the protective plate 67 also slides with the lower surface of the shield 601. Therefore, when the bent plate 64 is in a horizontal position, the protective plate 67 can slide a certain distance until the gap under the shield 601 is opened, so that the shield 601 can completely face the upper surface of the pipe 51.

[0058] Before the tapping chuck 43 rotates, the three-phase motor 61 at the bottom will also make the bent plate 64 gradually approach the upper pipe 51 during rotation, and finally drive the shield plates 601 on the upper and lower sides of the pipe 51 to fit together under the rotation of the bent plate 64. The lubricated tapping chuck 43 may throw the lubricating oil on the surface of the tapping chuck 43 to the outside during rotation. Therefore, it is necessary to set shield plates 601 on the upper and lower sides of the pipe 51 for protection, which can block the thrown lubricating oil and prevent the lubricating oil from falling to the outside. The shield plates 601 on the upper and lower sides are larger than the tapping chuck 43 and the pipe 51, and will not affect the operation of the tapping chuck 43 on the pipe 51. At the same time, part of the waste produced by the tapping chuck 43 tapping the pipe 51 will be directly pushed out of the pipe 51 due to the rotation of the tapping chuck 43, and then fall to the surface of the shield plate 601 below under the action of gravity.

[0059] After the tapping chuck 43 has completed tapping the pipe 51, the servo motor 42 needs to flip and drive the tapping chuck 43 to flip, and the electric slide rail 2 drives the servo motor 42 to move to the side away from the pipe 51. During the reversal of the servo motor 42, the tapping chuck 43 is prone to throw the lubricating oil and some debris attached to the surface to the outside during rotation, so the shielding plates 601 on the upper and lower sides need to surround and shield the tapping chuck 43. After the tapping chuck 43 is completely withdrawn from the inner wall of the pipe 51, the servo motor 42 stops rotating, and the slide rail 2 drives the support sleeve 41, the servo motor 42 and the tapping chuck 43 to move and reset.

[0060] When the electric rod 66 contracts and drives the protective plate 67 to move, the protective plate 67 can pull the scraper 72 to move along the surface of the limit shaft 71 through the pull ropes 74 on the left and right sides. During the movement of the scraper 72, the extrusion spring 73 is squeezed to a certain extent. The guide tube 75 provides support and guidance for the movement of the pull rope 74. The final position of the scraper 72 is close to the side of the guide tube 75.

[0061] When the tapping chuck 43 withdraws from the internal space surrounded by the upper and lower shields 601, the three-phase motor 61 reverses and controls the bent plate 64 to rotate toward the side away from the pipe 51 through the output shaft. The electric rod 66 extends and pushes the protective plate 67 to slide along the surface of the inclined block 69 toward the side close to the guide tube 75. The protective plate 67 can close the gap below the shield 601 during the sliding process to prevent the lubricating oil and debris attached to the surface from dripping down during the gradual lifting of the shield 601. When the protective plate 67 gradually approaches the guide tube 75, the scraper 72 cannot feel the pulling force of the pull rope 74, so the scraper 72 will be reset along the surface of the limit shaft 71 under the pressure of the extrusion spring 73. During the movement, the scraper 72 will move in contact with the lower surface of the shield 601 and scrape off the lubricating oil attached to the surface of the shield 601 and the tapping debris inside the lubricating oil. The scraped lubricating oil and debris slide down along the inner wall of the shield 601. At this time, the position of the shield 601 is similar to Figure 7 Therefore, the lubricating oil and the debris will gradually flow into the oil bag 68 at the bottom, so as to collect the lubricating oil and the debris. When the shield plate 601 gradually moves away from the pipe 51, that is, when it rotates downward, the larger tapping debris attached to the surface of the shield plate 601 falls into the material removal box 1 below under the force of gravity, and the lubricating oil and the debris on the surface of the shield plate 601 will slide along the shield plate 601 into the material removal box 1 below.

[0062] After the upper bent plate 64 is reset, the three-phase motor 61 rotates a certain angle again through the output shaft, that is, it can drive the bent plate 64 to rotate a certain angle toward the side of the water tank 81. The bent plate 64 will approach the limit tube 86 during the rotation. The slide plate 83 cannot feel the pulling force of the pull rope 85, so it will slide to the side away from the limit tube 86 under the pulling force of the tension spring 82. During the sliding process, the circular groove 84 will gradually slide to the top of the water pipe 54, that is, the gap between the slide plate 83 and the water pipe 54 is opened. The water inside the water tank 81 will flow into the inside of the water pipe 54 through the circular groove 84, and enter the inside of the flushing pipe 52 through the water pipe 54. The water inside the flushing pipe 52 will flow into the inside of the tapped pipe 51 to flush the debris and part of the lubricating oil inside the pipe 51. After flushing is completed, the three-phase motor 61 drives the bent plate 64 to rotate toward the side away from the limit tube 86 through the output shaft, so that the bent plate 64 returns to the position as shown in the figure. Figure 7 When the bent plate 64 moves away from the limiting tube 86 , the pull rope 85 pulls the slide plate 83 , so that the slide plate 83 slides a certain distance toward the limiting tube 86 , so that the circular groove 84 leaves the top of the water pipe 54 , and blocks the gap between the slide plate 83 and the water pipe 54 .
