Description

Technical Field

[0001] The present invention relates to the technical field of gas generators, and particularly to a production device for steel pipe parts of a gas generator. Background Technique

[0002] A gas generator is one of the components of an automotive safety system. When a vehicle collides, the gas generator inflates and deploys the airbag to protect the occupants. When assembling the gas generator, a steel pipe part is used as a container for the chemical reaction, and then the reaction substances are placed inside the steel pipe part. When processing the steel pipe part, processing equipment is required to chamfer and polish the steel pipe part to remove the burrs on the surface of the steel pipe part to ensure that the steel pipe part can be used normally.

[0003] In the prior art, during the process of chamfering and polishing the steel pipe part, a large amount of debris is generated, and then these debris are scattered on the surface of the processing equipment. In order to prevent the debris from interfering with the normal operation of the equipment, it is necessary to clean the debris regularly. However, during the cleaning process, due to the large scattering range of the debris, it is inconvenient to clean the debris.

[0004] Therefore, we propose a production device for steel pipe parts of a gas generator. Summary of the Invention

[0005] The purpose of the present invention is to provide a production device for steel pipe parts of a gas generator to solve the problems raised in the above background technique.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a production device for gas generator steel pipe fittings, comprising a workbench, a bracket is installed on the upper surface of the workbench, a control box is installed on the upper end of the bracket, a sliding frame is slidably connected to the surface of the bracket, the output end of the control box is transmission-connected to the sliding frame, three mechanical claws are installed on the lower end of the sliding frame, a chamfer is installed on the upper surface of the workbench, a grinder is installed on the upper surface of the workbench, a pipe diameter detector is installed on the upper surface of the workbench, the grinder is located between the chamfer and the pipe diameter detector, three clamps are installed on the upper surface of the workbench, and also include fixtures respectively arranged on the upper surface of the workbench for chamfering and A suction structure for sucking and cleaning debris generated during the grinding process, the suction structure comprising an air pump fixedly mounted on the upper surface of a workbench, a U-shaped tube for sucking the debris, a through hole for facilitating the entry of debris into the U-shaped tube, and a filter plate for filtering the debris; a storage structure respectively arranged at a position of the workbench relative to the U-shaped tube, for collecting debris falling from the inner wall of the U-shaped tube, the storage structure comprising two trapezoidal bars and a storage box for storing the debris; an anti-back-suction structure respectively arranged on the inner wall of the storage box, for preventing the debris on the inner wall of the storage box from being sucked back into the U-shaped tube as much as possible, the anti-back-suction structure comprising a support plate slidably connected to the inner wall of the storage box, and a magnet for attracting the debris.

[0007] The effects achieved by the above components are: by setting up a suction structure, the air flow rate can be accelerated with the help of an air pump, so that the debris is sucked into the U-shaped tube, thereby preventing the debris from being scattered on the surface of the processing equipment on a large scale, making it inconvenient to clean the debris; by setting up a storage structure, the position of the storage box is initially limited to below the mouth of the U-shaped tube, so that the storage box can collect the filtered debris conveniently, and then conveniently dump the debris in a concentrated manner; by setting up an anti-back-suction structure, the debris is attracted with the help of a magnet, thereby preventing the debris from entering the inner wall of the U-shaped tube again when the air pump is started again, thereby ensuring that the suction structure can operate normally, and can also improve the space utilization efficiency of the storage box to a certain extent.

[0008] Preferably, the air inlet end of the air pump is connected with an exhaust pipe, and the exhaust pipe is a rigid polyvinyl chloride pipe. The other end of the exhaust pipe is connected with a temporary storage pipe, and the lower end of the temporary storage pipe is connected with the U-shaped tube. The through hole is opened on the surface of the U-shaped tube, and the side wall of the U-shaped tube is fixedly connected with two mounting plates. The vertical cross-section of the mounting plate is "L"-shaped, and the lower end of the long arm of the mounting plate is horizontally slid through with a sliding rod, and the ends of the two sliding rods close to each other are fixedly connected with a rectangular plate, and the surface of the sliding rod is sleeved with a first spring, and the two ends of the first spring are respectively connected with the mounting plate. The mounting plate is fixedly connected to the rectangular plate, a baffle is fixedly connected to the upper surface of the rectangular plate, the baffle is slidably connected to the U-shaped tube, the size of the baffle is matched with the size of the through hole, four telescopic rods are fixedly connected to the top of the inner wall of the temporary storage tube, the lower end of the telescopic rod is fixedly connected to the filter plate, the filter plate is slidably connected to the inner wall of the temporary storage tube, two belts are fixedly connected to the lower surface of the filter plate, the belts pass through the temporary storage tube, the other end of the belts is fixedly connected to the rectangular plate, a clearance hole is opened on the surface of the mounting plate, and the belts pass through the clearance hole.

[0009] The effect achieved by the above components is: when debris is generated, the air pump is started, and the air inlet end of the air pump begins to suck air. At this time, the air will flow through the lower pipe opening of the U-shaped tube into the U-shaped tube, and then the air will squeeze the filter plate to make the filter plate move upward. At this time, the filter plate will compress the telescopic rod, and the telescopic rod will limit the sliding path of the filter plate. The sliding of the filter plate will cause the belt to slide through the temporary storage tube and the give way hole. At this time, the rectangular plate will move in the direction close to the long arm of the mounting plate due to the pulling of the belt. The sliding of the rectangular plate will squeeze the first spring and drive the slide rod to slide through the mounting plate. The sliding of the rectangular plate will cause the baffle to no longer block the through hole. At this time, the air containing debris will enter the U-shaped tube through the through hole, and then the air containing debris will flow into the temporary storage tube. The filter plate will filter the air containing debris. At this time, the debris will remain on the inner wall of the temporary storage tube and the lower surface of the filter plate. The temporary storage tube will temporarily store the debris, and then the filtered air will flow through the suction pipe and be discharged by the air pump.

[0010] Preferably, a roller is rotatably connected to one side of the long arm of the mounting plate close to the rectangular plate, and the arc surface of the roller is slidably connected to the belt.

[0011] The effect achieved by the above components is that when the belt slides along the arc surface of the roller, the roller can adjust the sliding direction of the belt.

[0012] Preferably, the vertical cross-section of the baffle is "U"-shaped, and the surfaces of the two side arms of the baffle are provided with a plurality of air holes, which are inclined upward from the side close to the U-shaped tube side arm to the side away from the U-shaped tube side arm.

[0013] The effect achieved by the above components is that the air holes can increase the speed at which air flows into the U-shaped tube.

[0014] Preferably, the sliding rod has a regular hexagonal prism structure and is made of stainless steel.

[0015] The effects achieved by the above components are as follows: Since the sliding rod has a regular hexagonal prism structure, the sliding rod can support the rectangular plate and limit the sliding path of the rectangular plate at the same time. And because the surface of the stainless steel sliding rod is relatively smooth and corrosion-resistant, the friction between the sliding rod and the mounting plate can be reduced, and the service life of the sliding rod can be extended.

[0016] Preferably, the trapezoidal strips are fixedly installed on the upper surface of the workbench. Connecting strips are slidably connected to the inclined surfaces of the two trapezoidal strips. The upper surface of the connecting strip is fixedly connected to the storage box. The connecting strip is slidably connected to the workbench, and the storage box is slidably connected to the trapezoidal strips. The size of the storage box is adapted to the size of the U-shaped tube. A circular tube is communicated with the bottom of the inner wall of the storage box. A plug rod slidably penetrates through the upper end of the circular tube. A trapezoidal plate is fixedly connected to the position of the workbench relative to the plug rod. A jack is opened on the upper surface of the trapezoidal plate. The size of the jack is adapted to the size of the plug rod. Both ends of the connecting strip are of a quarter frustum of a cone structure.

[0017] The effects achieved by the above components are as follows: Move the storage box. The movement of the storage box will drive the connecting strip to slide along the surface of the workbench. During this process, since both ends of the connecting strip are of a quarter frustum of a cone structure, it is more convenient to slide the connecting strip between the two trapezoidal strips. Then the connecting strip will slide along the inclined surface of the trapezoidal strip, and the storage box will slide along the upper surface of the trapezoidal strip. The trapezoidal strip plays a role in restricting the position of the connecting strip and thus restricting the position of the storage box. The circular tube will drive the plug rod to slide along the surface of the workbench with the movement of the storage box. Then the plug rod will slide along the inclined surface of the trapezoidal plate. At this time, the plug rod will move upward along the inner wall of the circular tube. When the plug rod is inserted into the inner wall of the jack, the jack plays a role in restricting the position of the plug rod and thus restricting the position of the storage box.

[0018] Preferably, a groove is opened on the upper surface of the trapezoidal plate. The groove is communicated with the jack. The size of the groove is adapted to the size of the plug rod.

[0019] The effects achieved by the above components are as follows: Sliding the storage box will cause the plug rod to slide into the inner wall of the groove. Then the plug rod will contact the inner wall of the jack. At this time, the groove can prevent the situation that the plug rod directly slides past the jack and is misaligned with the jack due to the too fast sliding speed of the storage box as much as possible.

[0020] Preferably, a counterweight block is fixedly connected to the upper end of the plug rod. Anti-slip grooves are opened on the arc surface of the counterweight block.

[0021] The effects achieved by the above components are as follows: The counterweight block will squeeze the plug rod under the influence of its own gravity. The counterweight block plays a role in facilitating the insertion of the plug rod into the jack.

[0022] Preferably, the pallet is slidably connected to the round tube. An L-shaped plate is fixedly connected to the upper surface of the pallet. A second spring is fixedly connected to the lower surface of the short arm of the L-shaped plate. A square plate is fixedly connected to the outer wall of the storage box. The other end of the second spring is fixedly connected to the square plate. Two clamping plates are fixedly connected to the lower surface of the pallet. The vertical cross-section of the clamping plate is in the shape of "F". The inner wall of the clamping plate is slidably connected to a magnet. The upper end of the magnet is slidably connected to the pallet.

[0023] The effects achieved by the above components are as follows: After the debris slides down along the inner wall of the U-shaped tube from the tube orifice of the U-shaped tube, the debris will fall onto the pallet in the storage box. At this time, the magnet will attract the debris, thereby minimizing the situation where the debris is sucked into the U-shaped tube again.

[0024] Preferably, two rectangular holes are provided on the side wall of the storage box, and the size of the rectangular holes is adapted to the size of the magnet.

[0025] The effects achieved by the above components are as follows: The rectangular holes facilitate pulling out the magnet from the clamping plate, thereby facilitating pouring out the debris from the storage box.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By providing a suction structure, the present invention can accelerate the air flow rate with the help of an air pump, so that the debris is sucked into the U-shaped tube, thereby minimizing the situation where the debris is scattered over a large area on the surface of the processing equipment and is inconvenient to clean. Then, the filter plate filters the air, and the debris is temporarily stored in the temporary storage tube, which is convenient for subsequent centralized treatment of the debris and improves the practicability of the processing equipment.

[0028] 2. By providing a storage structure, the present invention initially limits the position of the storage box below the orifice of the U-shaped tube with the help of the trapezoidal strip and the connecting strip, thereby facilitating the storage box to collect the filtered debris and facilitating the centralized pouring of the debris.

[0029] 3. By providing an anti-backflow structure, the present invention attracts the debris with a magnet, thereby minimizing the situation where the debris enters the inner wall of the U-shaped tube again when the air pump is started again, ensuring the normal operation of the suction structure, and also improving the space utilization efficiency of the storage box to a certain extent.

Detailed implementation manners

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 - 13 The present invention provides a technical solution: a production device for gas generator steel pipe fittings, comprising a workbench 1, a bracket 2 is installed on the upper surface of the workbench 1, a control box 3 is installed on the upper end of the bracket 2, a sliding frame 4 is slidably connected to the surface of the bracket 2, the output end of the control box 3 is transmission-connected to the sliding frame 4, three mechanical claws 5 are installed on the lower end of the sliding frame 4, a chamfering device 10 is installed on the upper surface of the workbench 1, a grinder 11 is installed on the upper surface of the workbench 1, a pipe diameter detector 12 is installed on the upper surface of the workbench 1, the grinder 11 is located between the chamfering device 10 and the pipe diameter detector 12, and the workbench 10 is installed on the upper surface of the workbench 10. The upper surface of the workbench 1 is provided with three fixtures 9, and also includes a suction structure 6 respectively arranged on the upper surface of the workbench 1 for sucking and cleaning the debris generated during the chamfering and grinding of the steel pipe fittings. The suction structure 6 includes an air pump 601 fixedly installed on the upper surface of the workbench 1, a U-shaped tube 604 for sucking the debris, a through hole 605 for facilitating the debris to enter the U-shaped tube 604, and a filter plate 611 for filtering the debris. By setting the suction structure 6, the air flow rate can be accelerated with the help of the air pump 601, so that the debris is sucked into the U-shaped tube 60 4, thereby preventing the debris from being scattered on the surface of the processing equipment in a large range, making it inconvenient to clean up the debris; respectively arranged at the position of the workbench 1 relative to the U-shaped tube 604, a storage structure 7 for collecting the debris falling from the inner wall of the U-shaped tube 604, the storage structure 7 includes two trapezoidal bars 71 and a storage box 73 for storing the debris. By setting the storage structure 7, the position of the storage box 73 is initially limited to below the tube mouth of the U-shaped tube 604, so that the storage box 73 is convenient for collecting the filtered debris, and then convenient for the centralized dumping of the debris; respectively An anti-back-suction structure 8 is arranged on the inner wall of the storage box 73 to prevent debris on the inner wall of the storage box 73 from being sucked back into the U-shaped tube 604 as much as possible. The anti-back-suction structure 8 includes a support plate 81 slidably connected to the inner wall of the storage box 73 and a magnet 86 for attracting the debris. By setting the anti-back-suction structure 8, the debris is attracted with the help of the magnet 86, so as to prevent the debris from entering the inner wall of the U-shaped tube 604 again when the air pump 601 is started again, thereby ensuring the normal operation of the suction structure 6 and improving the space utilization efficiency of the storage box 73 to a certain extent.

[0046] Specifically describe the specific settings and functions of its suction structure 6, storage structure 7, and anti-backflow structure 8 below.

[0047] Referring to Figures 4 - 8 As shown, in this implementation: the intake end of the air pump 601 is connected to an air suction pipe 602. The air suction pipe 602 is a rigid polyvinyl chloride pipe. The other end of the air suction pipe 602 is connected to a temporary storage pipe 603. The lower end of the temporary storage pipe 603 is connected to a U-shaped pipe 604. A through hole 605 is opened on the surface of the U-shaped pipe 604. Two mounting plates 606 are fixedly connected to the side wall of the U-shaped pipe 604. The vertical cross-section of the mounting plate 606 is in an "L" shape. A sliding rod 607 horizontally slides through the lower end of the long arm of the mounting plate 606. Rectangular plates 608 are fixedly connected to the ends of the two sliding rods 607 close to each other. A first spring 614 is sleeved on the surface of the sliding rod 607. The two ends of the first spring 614 are fixedly connected to the mounting plate 606 and the rectangular plate 608 respectively. A baffle 609 is fixedly connected to the upper surface of the rectangular plate 608. The baffle 609 is slidably connected to the U-shaped pipe 604. The size of the baffle 609 is adapted to the size of the through hole 605. Four telescopic rods 610 are fixedly connected to the top inner wall of the temporary storage pipe 603. The lower ends of the telescopic rods 610 are fixedly connected to a filter plate 611. The filter plate 611 is slidably connected to the inner wall of the temporary storage pipe 603. Two belts 612 are fixedly connected to the lower surface of the filter plate 611. The belts 612 penetrate through the temporary storage pipe 603. The other ends of the belts 612 are fixedly connected to the rectangular plate 608. A relief hole 613 is opened on the surface of the mounting plate 606. The belts 612 penetrate through the relief hole 613. When debris is generated, start the air pump 601. The intake end of the air pump 601 starts to suck air. At this time, the air will flow through the lower pipe orifice of the U-shaped pipe 604 and enter the U-shaped pipe 604. Then the air will squeeze the filter plate 611, causing the filter plate 611 to move upward. At this time, the filter plate 611 will compress the telescopic rods 610, and the telescopic rods 610 play a role in restricting the sliding path of the filter plate 611. The sliding of the filter plate 611 will drive the belts 612 to slide through the temporary storage pipe 603 and the relief hole 613. At this time, the rectangular plate 608 will move in the direction close to the long arm of the mounting plate 606 due to the pulling of the belts 612. The sliding of the rectangular plate 608 will squeeze the first spring 614 and drive the sliding rod 607 to slide through the mounting plate 606. The sliding of the rectangular plate 608 will cause the baffle 609 to no longer block the through hole 605. At this time, the air containing debris will enter the U-shaped pipe 604 through the through hole 605, and then the air containing debris will flow into the temporary storage pipe 603. The filter plate 611 will filter the air containing debris. At this time, the debris will remain on the inner wall of the temporary storage pipe 603 and the lower surface of the filter plate 611. The temporary storage pipe 603 will temporarily store the debris. Then the filtered air will flow through the air suction pipe 602 and be discharged by the air pump 601.

[0048] Referring to Figure 8 and Figure 9As shown, specifically, a roller 615 is rotatably connected to one side of the long arm of the mounting plate 606 close to the rectangular plate 608. The arc surface of the roller 615 is slidably connected to the belt 612. When the belt 612 slides along the arc surface of the roller 615, the roller 615 serves to adjust the sliding direction of the belt 612. The vertical cross-section of the baffle 609 is in a "U" shape, and a number of ventilation holes 616 are formed on the surfaces of both side arms of the baffle 609. The ventilation holes 616 are inclined upward from the side close to the side arm of the U-shaped tube 604 to the side far from the side arm of the U-shaped tube 604, and the ventilation holes 616 serve to increase the speed of air flowing into the U-shaped tube 604. The sliding rod 607 has a regular hexagonal prism structure and is made of stainless steel. Due to the regular hexagonal prism structure of the sliding rod 607, the sliding rod 607 can support the rectangular plate 608 while restricting the sliding path of the rectangular plate 608. Also, because the surface of the stainless steel sliding rod 607 is relatively smooth and corrosion-resistant, the friction between the sliding rod 607 and the mounting plate 606 can be reduced, and the service life of the sliding rod 607 can be extended.

[0049] Refer to Figure 10 and Figure 11 as well as Figure 12As shown in the figure, specifically, the trapezoidal strip 71 is fixedly installed on the upper surface of the workbench 1. The inclined surfaces of the two trapezoidal strips 71 are both slidably connected with a connecting strip 72. The upper surface of the connecting strip 72 is fixedly connected with a storage box 73. The connecting strip 72 is slidably connected with the workbench 1, and the storage box 73 is slidably connected with the trapezoidal strip 71. The size of the storage box 73 is adapted to the size of the U-shaped tube 604. The bottom of the inner wall of the storage box 73 is communicated with a circular tube 74. A plug rod 75 is slidably penetrated through the upper end of the circular tube 74. A trapezoidal plate 76 is fixedly connected to the position of the workbench 1 relative to the plug rod 75. A jack 77 is opened on the upper surface of the trapezoidal plate 76. The size of the jack 77 is adapted to the size of the plug rod 75. Both ends of the connecting strip 72 are of a quarter frustum structure. Moving the storage box 73 will drive the connecting strip 72 to slide along the surface of the workbench 1. During this process, since both ends of the connecting strip 72 are of a quarter frustum structure, it is more convenient to slide the connecting strip 72 between the two trapezoidal strips 71. After that, the connecting strip 72 will slide along the inclined surface of the trapezoidal strip 71, and the storage box 73 will slide along the upper surface of the trapezoidal strip 71. The trapezoidal strip 71 plays a role in restricting the position of the connecting strip 72 and thus restricting the position of the storage box 73. The circular tube 74 will drive the plug rod 75 to slide along the surface of the workbench 1 by means of the movement of the storage box 73. After that, the plug rod 75 will slide along the inclined surface of the trapezoidal plate 76. At this time, the plug rod 75 will move upward along the inner wall of the circular tube 74. When the plug rod 75 is inserted into the inner wall of the jack 77, the jack 77 plays a role in restricting the position of the plug rod 75 and thus restricting the position of the storage box 73. A groove 78 is opened on the upper surface of the trapezoidal plate 76. The groove 78 is communicated with the jack 77. The size of the groove 78 is adapted to the size of the plug rod 75. Sliding the storage box 73 will cause the plug rod 75 to slide into the inner wall of the groove 78. After that, the plug rod 75 will contact the inner wall of the jack 77. At this time, the groove 78 can prevent as much as possible the situation that the plug rod 75 directly slides past the jack 77 and is misaligned with the jack 77 due to the too fast sliding speed of the storage box 73. A counterweight block 79 is fixedly connected to the upper end of the plug rod 75. Anti-slip grooves are opened on the arc surface of the counterweight block 79. The counterweight block 79 will press the plug rod 75 under the influence of its own gravity. The counterweight block 79 plays a role in facilitating the insertion of the plug rod 75 into the jack 77.

[0050] Referring to Figure 11 and Figure 12 as well as Figure 13As shown, specifically, the pallet 81 is slidably connected to the circular tube 74. The upper surface of the pallet 81 is fixedly connected with an L-shaped plate 83. The lower surface of the short arm of the L-shaped plate 83 is fixedly connected with a second spring 84. The outer wall of the storage box 73 is fixedly connected with a square plate 82. The other end of the second spring 84 is fixedly connected with the square plate 82. The lower surface of the pallet 81 is fixedly connected with two clamping plates 85. The vertical cross-section of the clamping plate 85 is in the shape of "F". The inner wall of the clamping plate 85 is slidably connected with a magnet 86. The upper end of the magnet 86 is slidably connected with the pallet 81. After the debris slides down along the inner wall of the U-shaped tube 604 from the orifice of the U-shaped tube 604, the debris will fall onto the upper surface of the pallet 81 in the storage box 73. At this time, the magnet 86 will attract the debris, thus preventing the debris from being sucked into the U-shaped tube 604 again as much as possible. Two rectangular holes 87 are formed in the side wall of the storage box 73. The size of the rectangular hole 87 is adapted to the size of the magnet 86. The rectangular hole 87 serves to facilitate the extraction of the magnet 86 from the clamping plate 85, thereby facilitating the pouring out of the debris from the storage box 73.

[0051] Working principle: When processing steel pipe fittings, the control box 3 will drive the sliding frame 4 to move from the pipe diameter detector 12 towards the chamfering device 10. Then the fixture 9 will open. After that, the mechanical claws 5 will move downward. One of the mechanical claws 5 will grip the un-chamfered steel pipe fitting, the middle mechanical claw 5 will grip the chamfered steel pipe fitting, and the other mechanical claw 5 will grip the polished steel pipe fitting. Then the mechanical claws 5 will move upward. Then the control box 3 will drive the sliding frame 4 to slide in the opposite direction. Then the mechanical claws 5 will move downward again, so as to place the unprocessed steel pipe fitting into the fixture 9 aligned with the chamfering device 10, place the chamfered steel pipe fitting into the fixture 9 aligned with the polishing device 11, and place the chamfered and polished steel pipe fitting into the fixture 9 aligned with the pipe diameter detector 12. Then the fixture 9 will clamp the steel pipe fitting. Then the chamfering device 10 will chamfer the steel pipe fitting first, the polishing device 11 will polish the chamfered steel pipe fitting smoothly, and the pipe diameter detector 12 will detect whether the processed steel pipe fitting is qualified, thus realizing the processing of the steel pipe fitting.

[0052] During the processing, first move the storage box 73. The movement of the storage box 73 will drive the connecting bar 72 to slide along the surface of the workbench 1. During this process, since both ends of the connecting bar 72 are quarter frustum structures, it is more convenient to slide the connecting bar 72 between the two trapezoidal bars 71. After that, the connecting bar 72 will slide along the inclined surface of the trapezoidal bar 71, and the storage box 73 will slide along the upper surface of the trapezoidal bar 71. The trapezoidal bar 71 plays a role in restricting the position of the connecting bar 72 and thus restricting the position of the storage box 73. The round tube 74 will drive the insertion rod 75 to slide along the surface of the workbench 1 by means of the movement of the storage box 73. After that, the insertion rod 75 will slide along the inclined surface of the trapezoidal plate 76. At this time, the insertion rod 75 will move upward along the inner wall of the round tube 74. Continuing to slide the storage box 73 will cause the insertion rod 75 to slide into the inner wall of the groove 78. After that, the insertion rod 75 will contact the inner wall of the jack 77. At this time, the groove 78 can prevent, as much as possible, the situation where the insertion rod 75 directly slides past the jack 77 and is misaligned with the jack 77 due to the too fast sliding speed of the storage box 73. After that, the counterweight 79 will squeeze the insertion rod 75 under the influence of its own gravity, and the insertion rod 75 will be inserted downward into the inner wall of the jack 77. The jack 77 plays a role in restricting the position of the insertion rod 75 and thus restricting the position of the storage box 73.

[0053] When debris is generated, the air pump 601 is started, and the air inlet end of the air pump 601 begins to suck air. At this time, the air will flow through the lower nozzle of the U-shaped tube 604 and the ventilation holes 616 into the U-shaped tube 604. The ventilation holes 616 serve to increase the speed of the air flowing into the U-shaped tube 604. Then, the air will squeeze the filter plate 611, causing the filter plate 611 to move upward. At this time, the filter plate 611 will compress the telescopic rod 610, and the telescopic rod 610 serves to limit the sliding path of the filter plate 611. When the filter plate 611 slides, the belt 612 will slide through the temporary storage tube 603 and the relief hole 613, and the belt 612 will also slide along the arc surface of the roller 615. The roller 615 serves to adjust the sliding direction of the belt 612. At this time, the rectangular plate 608 will move toward the long arm of the mounting plate 606 due to the pulling of the belt 612. When the rectangular plate 608 slides, it will squeeze the first spring 614 and drive the slide bar 607 to slide through the mounting plate 606. Since the slide bar 607 has a regular hexagonal prism structure, the slide bar 607 can support the rectangular plate 608 while also limiting the sliding path of the rectangular plate 608. And because the surface of the stainless steel slide bar 607 is relatively smooth and corrosion-resistant, the friction between the slide bar 607 and the mounting plate 606 can be reduced, and the service life of the slide bar 607 can be extended. When the rectangular plate 608 slides, the baffle 609 will no longer block the through hole 605. At this time, the air containing debris will enter the U-shaped tube 604 through the through hole 605, and then the air containing debris will flow into the temporary storage tube 603. The filter plate 611 will filter the air containing debris. At this time, the debris will remain on the inner wall of the temporary storage tube 603 and the lower surface of the filter plate 611. The temporary storage tube 603 will temporarily store the debris. Then, the filtered air will flow through the air extraction pipe 602 and be discharged by the air pump 601. When the processing is completed, the air pump 601 is turned off. At this time, the suction force of the air pump 601 disappears, and the first spring 614 begins to stretch. The two rectangular plates 608 will slide toward each other by means of the tension of the two first springs 614 respectively. When the rectangular plate 608 slides, the two baffles 609 will contact each other, and the two baffles 609 will block the through hole 605. At the same time, the debris will slide downward along the inner wall of the temporary storage tube 603 under the influence of its own gravity. Then, the debris will slide onto the inner wall of the U-shaped tube 604 and the surface of the baffle 609. The baffle 609 can prevent the debris from falling onto the surface of the steel pipe part through the through hole 605 as much as possible, thereby preventing the debris from interfering with the subsequent detection of the steel pipe part as much as possible. At this time, since the ventilation holes 616 are inclined upward from the side close to the side arm of the U-shaped tube 604 to the side away from the side arm of the U-shaped tube 604, the debris will not slide into the ventilation holes 616. Then, the debris will slide down along the inner wall of the U-shaped tube 604 from the nozzle of the U-shaped tube 604, and then the debris will fall onto the tray 81 in the storage box 73. At this time, the magnet 86 will attract the debris, thereby preventing the debris from being sucked into the U-shaped tube 604 again as much as possible. And because the vertical section of the magnet 86 is approximately triangular,Therefore, the magnetic force of the magnet 86 in the middle of the tray 81 is greater than that at both ends of the tray 81, so that the debris can move as much as possible towards the middle of the storage box 73 during the falling process, and thus prevent the debris from accumulating on both sides of the inner wall of the storage box 73 as much as possible, which may lead to the situation that the space in the middle of the storage box 73 is difficult to utilize. As the debris accumulates, the debris will squeeze the tray 81 under the influence of its own gravity, causing the tray 81 to move downward along the inner wall of the storage box 73 and the arc surface of the circular tube 74. The sliding of the tray 81 will drive the L-shaped plate 83 to slide downward, and the sliding of the L-shaped plate 83 will squeeze the second spring 84, and at this time, the second spring 84 is in a compressed state.

[0054] When the storage box 73 is full, pull up the counterweight 79. At this time, the anti-slip grooves on the arc surface of the counterweight 79 can increase the friction on the surface of the counterweight 79. The movement of the counterweight 79 will drive the insertion rod 75 to move upward, and the counterweight 79 serves to facilitate the pulling of the insertion rod 75. When the insertion rod 75 is pulled out from the inner wall of the jack 77, the storage box 73 can be pulled horizontally again. When the connecting strip 72 is separated from the trapezoidal strip 71, the storage box 73 can be removed. Then, the magnet 86 is pulled out from the inner wall of the clamping plate 85 through the rectangular hole 87. At this time, the magnet 86 will no longer attract the debris. Then, the storage box 73 can be moved to pour out the debris, and the second spring 84 begins to stretch. The L-shaped plate 83 will drive the tray 81 to slide upward by means of the tension of the second spring 84, so that the tray 81 is close to the debris generation area near the processing point, which further facilitates the magnet 86 to attract the debris.
