Description

Technical Field

[0001] This application relates to the field of workpiece processing, and in particular to a device for cleaning the inner hole of a long-hole workpiece. Background Technology

[0002] The common rail fuel system, commonly known as the high-pressure common rail direct injection system, is an advanced fuel injection technology widely used in modern diesel engines. The processing of the common rail fuel system involves purchasing blanks of the corresponding shape and machining various hole structures and thread structures on the blanks. The blanks are cylindrical and have evenly distributed convex fuel injectors on their sides.

[0003] In the machining of common rail fuel, it is necessary to drill holes in the common rail. After drilling, there may be flying debris inside the holes of the common rail fuel. In order to clean the flying debris inside the holes of the common rail fuel, the holes of the common rail fuel are usually directly inserted into a rotating grinding head, and the grinding head is used to clean the inner wall of the holes.

[0004] However, during the cleaning process, most people simply hold the fuel common rail directly and insert the grinding head. During insertion, the fuel common rail may shift, potentially causing the grinding head to damage the inner wall of the fuel common rail hole. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that most of the methods involve directly holding the fuel common rail and then inserting the grinding head, which may cause the fuel common rail to shift during the insertion process, potentially damaging the inner wall of the fuel common rail hole. This application provides a device for cleaning the inner hole of a long-hole workpiece.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A device for cleaning the inner hole of a long-hole workpiece includes a support base, a grinding motor fixed on the support base, a rotating shaft fixed at the output end of the grinding motor, a grinding head fixed at the end of the rotating shaft away from the grinding and cleaning motor, a moving mechanism and a fixing mechanism on the support base, a controller on one side of the support base, and a common rail fuel system on the support base.

[0008] By adopting the above technical solution, the fuel common rail that needs to be cleaned is placed on the fixed structure. The fixing mechanism fixes the fuel common rail, and then the moving mechanism drives the fixing mechanism, which in turn drives the fuel common rail. Then, the grinding head is inserted into the inner hole of the fuel common rail from one end, and then the grinding head grinds and cleans the fuel common rail. This allows the grinding head to be inserted smoothly into the fuel common rail, reducing the possibility of grinding head deviation and facilitating the cleaning of the inner hole of the fuel common rail.

[0009] Furthermore, the moving mechanism includes a moving rail fixed on a support base, a pneumatic block slidably connected to the moving rail, and a sensing component provided at the end of the pneumatic block near the grinding and cleaning motor.

[0010] By adopting the above technical solution, the pneumatic block drives the fuel common rail to move on the moving rail, allowing the grinding head to be smoothly inserted into the fuel common rail, thereby reducing the possibility of the grinding head deviating.

[0011] Furthermore, the sensing component includes a sensing support plate fixed to one side of the support base, a sensing head fixed on the sensing support plate, and the controller fixedly connected to the sensing support plate.

[0012] By adopting the above technical solution, when the fuel common rail moves to the position of the sensing support plate, the common rail triggers the sensing head, and then the pneumatic block moves back to the initial position, so that the grinding head can grind and clean the inner hole of the fuel common rail again.

[0013] Furthermore, a limiting plate is provided on one side of the sensing support plate, and the limiting plate is fixedly connected to the moving rail.

[0014] By adopting the above technical solution, an upper limit plate is fixed on the moving rail. The limit plate blocks the pneumatic block, thereby further reducing the possibility of the pneumatic block moving too far.

[0015] Furthermore, the fixing mechanism includes a fixing seat fixed on the pneumatic block, the fixing seat having a fixing groove, the fixing groove being an arc-shaped groove with open ends, and the fixing seat being provided with an abutment component.

[0016] By adopting the above technical solution, the common fuel rail is placed in the fixing groove on the fixing seat, and then the fuel rail is abutted by the abutting component, which can facilitate the fixing of the common fuel rail and reduce the possibility of fuel rail misalignment.

[0017] Furthermore, the abutment assembly includes a support frame fixed on a fixed base, an abutment block slidably connected to the support frame, an abutment threaded rod rotatably connected to the abutment block, the abutment threaded rod passing through the support frame and threadedly connected to the support frame.

[0018] By adopting the above technical solution, rotating the threaded rod causes the threaded rod to drive the contact block, which then contacts the common fuel rail, thereby allowing the common fuel rail to be stably fixed on the mounting base.

[0019] Furthermore, the fixing base is provided with a placement groove, which is connected to the fixing groove.

[0020] By adopting the above technical solution, when placing the common rail fuel injector into the fixing groove, the nozzle on the common rail fuel injector is oriented towards the groove, thereby reducing the possibility of bumping into the common rail fuel injector.

[0021] Furthermore, a cleaning plate is provided on one side of the support base, and several rubber tubes are fixed on the cleaning plate. A cleaning needle is provided on one side of the cleaning plate.

[0022] By adopting the above technical solution, the rubber tube on the cleaning plate is inserted into the fuel injector on the common rail, and then the cleaning needle is inserted into the rubber tube, which can reduce the clogging of the fuel injector by flying debris in the common rail, and at the same time reduce the wear of the cleaning needle on the inner wall of the fuel injector of the common rail.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application, by aligning the nozzle on the common fuel rail with the placement groove, and then rotating the abutting threaded rod, causes the abutting block to abut against the common fuel rail, thus stably fixing the common fuel rail to the mounting base. Then, the controller starts the grinding and cleaning motor, which drives the rotating shaft to rotate. The rotating shaft then drives the grinding head to rotate, and a pneumatic block moves the mounting base along the moving rail towards the grinding head. The pneumatic block slowly brings the common fuel rail closer to the grinding head, and the grinding head enters the common fuel rail. When the common fuel rail reaches the position of the sensing support plate, it triggers the sensing head (a laser sensor). The pneumatic block then moves back to its initial position, allowing the grinding head to grind and clean the inner hole of the common fuel rail again. This achieves the goal of ensuring the grinding head can be smoothly inserted into the common fuel rail, reducing the possibility of grinding head deviation, and facilitating the cleaning of the inner hole of the common fuel rail.

[0025] 2. In this application, after the common rail is ground and cleaned, a rubber tube on the cleaning plate is inserted into the fuel injector on the common rail. Then, a cleaning needle is inserted into the rubber tube to clean the debris in the common rail. This achieves the purpose of reducing the clogging of the fuel injector by the debris in the common rail, and at the same time reducing the wear of the cleaning needle on the inner wall of the fuel injector of the common rail.

[0030] The following is in conjunction with the appendix Figure 1 —2 provides further detailed description of this application.

[0031] This application discloses an internal hole cleaning device for long-hole workpieces.

[0032] Reference Figure 1 and Figure 2 A device for cleaning the inner hole of a long-hole workpiece includes a support base 1, a grinding motor fixed on the support base 1, a rotating shaft 3 fixed at the output end of the grinding motor, a grinding head 4 fixed at the end of the rotating shaft 3 away from the grinding and cleaning motor 2, a moving mechanism 5 and a fixing mechanism 6 on the support base 1, a controller 7 on one side of the support base 1, and a fuel common rail 8 on the support base 1.

[0033] When the cleaning device is needed, first place the fuel common rail 8 to be cleaned on the fixed structure. The fixing mechanism 6 fixes the fuel common rail 8. Then, the controller 7 starts the grinding and cleaning motor 2, which drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the grinding head 4 to rotate. Then, the moving mechanism 5 drives the fixing mechanism 6, which in turn drives the fuel common rail 8. The grinding head 4 is then inserted into the inner hole of the fuel common rail 8 from one end. The grinding head 4 then grinds and cleans the fuel common rail 8. After the grinding and cleaning is completed, the moving mechanism 5 is reset. Then, the fixing mechanism 6 is used to remove the fuel common rail 8. By fixing the fuel common rail 8 with the fixing mechanism 6 and then moving the fuel common rail 8 with the moving mechanism 5, the grinding head 4 can be inserted into the fuel common rail 8. This allows the grinding head 4 to be inserted smoothly into the fuel common rail 8, reducing the possibility of the grinding head 4 shifting and facilitating the cleaning of the inner hole of the fuel common rail 8.

[0034] Reference Figure 1 and Figure 2 The moving mechanism 5 includes a moving rail 51 fixed on the support base 1, a pneumatic block 52 slidably connected on the moving rail 51, and a sensing component 53 is provided at one end of the pneumatic block 52 near the grinding and cleaning motor 2.

[0035] In addition, the sensing component 53 includes a sensing support plate 531 fixed to one side of the support base 1, a sensing head 532 fixed on the sensing support plate 531, and a controller 7 fixedly connected to the sensing support plate 531.

[0036] Furthermore, a limit plate 533 is provided on one side of the sensing support plate 531, and the limit plate 533 is fixedly connected to the moving rail 51.

[0037] After the common rail 8 is fixed, the pneumatic block 52 moves along the moving rail 51 toward the grinding head 4. The pneumatic block 52 drives the common rail 8 to slowly approach the grinding head 4, and then the grinding head 4 enters the common rail 8. When the common rail 8 moves to the position of the sensing support plate 531, the common rail triggers the sensing head 532, which is a laser sensor. Then the pneumatic block 52 moves back to the initial position, allowing the grinding head 4 to grind and clean the inner hole of the common rail 8 again. When the common rail 8 is completely detached from the grinding head 4, the grinding and cleaning of the common rail 8 is completed. By using the pneumatic block 52 to drive the common rail 8 to move, the grinding head 4 can be smoothly inserted into the common rail 8, reducing the possibility of the grinding head 4 deviating, and further reducing the flying debris in the common rail 8.

[0038] Reference Figure 1 and Figure 2 The fixing mechanism 6 includes a fixing seat 61 fixed on the pneumatic block 52. The fixing seat has a fixing groove 62, which is an arc-shaped groove with open ends. The fixing seat 61 is provided with an abutment component 63.

[0039] In addition, the abutment component 63 includes a support frame 631 fixed on the fixed base 61, an abutment block 632 slidably connected to the support frame 631, an abutment threaded rod 633 rotatably connected to the abutment block 632, the abutment threaded rod 633 passes through the support frame 631 and is threadedly connected to the support frame 631.

[0040] Furthermore, the mounting base 61 is provided with a placement groove 64, which is connected to the mounting groove 62.

[0041] When fixing the common rail fuel 8, first place the common rail fuel 8 into the fixing groove 62 on the fixing seat 61. When placing the common rail fuel 8 into the fixing groove 62, make the nozzle on the common rail fuel 8 face the placement groove 64. Then rotate the abutting threaded rod 633, so that the abutting threaded rod 633 drives the abutting block 632. The abutting block 632 abuts against the common rail fuel 8, so that the common rail fuel 8 is stably fixed on the fixing seat 61. Then the pneumatic block 52 drives the fixing seat 61 to move. By placing the common rail fuel 8 into the fixing groove 62 and then using the abutting block 632 to abut, the common rail fuel 8 can be firmly fixed, making it easier for the grinding head 4 to enter the common rail fuel 8 and reducing the possibility of misalignment between the grinding head 4 and the common rail fuel 8.

[0042] Reference Figure 1 and Figure 2 A cleaning plate 9 is provided on one side of the support base 1. Several rubber tubes 10 are fixed on the cleaning plate 9, and a cleaning needle 11 is provided on one side of the cleaning plate 9. After the fuel common rail 8 is ground and cleaned, the rubber tubes 10 on the cleaning plate 9 are inserted into the fuel injectors on the fuel common rail 8. Then, the cleaning needle 11 is inserted into the rubber tubes 10 to clean the flying debris in the fuel common rail 8. By inserting the rubber tubes 10 into the fuel injectors in the fuel common rail 8 and then using the cleaning needle 11, the clogging of the fuel injectors by flying debris in the fuel common rail 8 can be reduced, and the wear of the inner wall of the fuel injectors by the cleaning needle 11 can be reduced.

[0043] Working principle: First, the common rail fuel 8 is placed in the fixing groove 62 on the fixing seat 61. When placing the common rail fuel 8 in the fixing groove 62, the nozzle on the common rail fuel 8 is facing the placement groove 64. Then, the abutting threaded rod 633 is rotated, causing the abutting threaded rod 633 to drive the abutting block 632. The abutting block 632 abuts against the common rail fuel 8, making the common rail fuel 8 stably fixed on the fixing seat 61. Then, the grinding and cleaning motor 2 is started by the controller 7, causing the grinding and cleaning motor 2 to drive the rotating shaft 3 to rotate. The rotating shaft 3 drives the grinding head 4 to rotate. Then, the pneumatic block 52 drives the fixing seat 61 to move, causing the pneumatic block 52 to move along the moving rail 51 towards the grinding head 4. 52 drives the common rail fuel 8 to slowly approach the grinding head 4, and then the grinding head 4 enters the common rail fuel 8. When the common rail fuel 8 moves to the position of the sensing support plate 531, the common rail triggers the sensing head 532, which is a laser sensor. Then the pneumatic block 52 moves back to the initial position, allowing the grinding head 4 to grind and clean the inner hole of the common rail fuel 8 again. When the common rail fuel 8 is completely separated from the grinding head 4, the grinding and cleaning of the common rail fuel 8 is completed. After the common rail fuel 8 is ground and cleaned, the rubber tube 10 on the cleaning plate 9 is inserted into the fuel injector on the common rail fuel 8, and then the cleaning needle 11 is inserted into the rubber tube 10 to clean the flying debris in the common rail fuel 8.
