Description

Technical Field

[0001] The present invention relates to the technical field of common rail pipe detection, and in particular to a detection device for machining engine common rail pipes. Background Art

[0002] The engine common rail pipe is a key component in the diesel fuel supply system. Its main function is to accumulate and distribute high-pressure fuel and reduce pressure fluctuations. The common rail pipe is part of the common rail system, which consists of a high-pressure fuel pump, a pressure sensor, an ECU (engine control unit), etc., forming a closed-loop fuel supply system. After the common rail pipe is machined, in order to ensure the airtightness of the common rail pipe, a detection device is required to detect the machined common rail pipe;

[0003] In the existing detection device for machining engine common rail pipes, the workpiece is clamped and fixed by the clamping component at the top of the bracket. At the same time, the first positioning component and the second positioning component are used for auxiliary positioning, ensuring that the workpiece is firmly fixed while the positioning accuracy is also guaranteed. The loading operation is simple and convenient, and the detection efficiency is high;

[0004] However, during the inspection of the common rail pipe, it is necessary to manually operate the first positioning component and the second positioning component to clamp and position the common rail pipe, and it is also necessary to manually connect the airtightness detection mechanism to the clamped common rail pipe for detection. After the detection, it is necessary to manually loosen the common rail pipe and remove the detected common rail pipe. In this way, when detecting a large number of common rail pipes, the operation is time-consuming and laborious, reducing the detection work efficiency. Summary of the Invention

Detailed implementation manners

[0030] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 9 drawings.

[0031] An inspection device for the processing of engine common rail pipes according to an embodiment of the present invention includes an inspection table 1 and support legs 2. Support legs 2 are provided at the four corners under the inspection table 1. A bottom plate 13 is fixedly installed below the four support legs 2. A material lifting structure is arranged at a position close to the middle on the upper surface of the bottom plate 13. A feeding port 3 is opened in the middle of the inspection table 1. An automatic inspection structure is arranged on the inspection table 1. A feeding structure is arranged on the right two support legs 2. A material collecting structure is arranged below the feeding structure on the right two support legs 2;

[0032] The automatic inspection structure includes fixing plates 8 connected to the inspection table 1 near the four corners at the bottom. A guide rod 9 is fixedly connected between the two front fixing plates 8. A bidirectional screw 12 is rotatably passed through the two rear fixing plates 8. The thread directions at the left and right ends of the bidirectional screw 12 are opposite. A first motor 11 is installed on one of the rear fixing plates 8. One end of the output shaft of the first motor 11 is connected to the bidirectional screw 12. First moving plates 4 are movably sleeved near both ends of the guide rod 9. A driving structure is arranged between the first moving plate 4 and the material lifting structure. A threaded groove for the bidirectional screw 12 to pass through is opened at the rear end of the first moving plate 4. The middle position on the upper surface of the first moving plate 4 is inserted into the feeding port 3. Vertical plates 5 are connected to the middle positions on the upper surfaces of the two first moving plates 4. Pressing blocks 6 are installed at the top ends of the mutually approaching side surfaces of the two vertical plates 5. Sealing rings 7 are arranged at the edges of the pressing blocks 6. An airtightness detection mechanism is arranged on the two vertical plates 5;

[0033] The airtightness detection mechanism includes an air inflation cylinder 22 installed at the top of the side surface of the left vertical plate 5 away from the abutting block 6. An air inflation hole is opened in the left abutting block 6, and the left abutting block 6 communicates with the air inflation cylinder 22. A piston rod 23 is movably inserted at the left end of the air inflation cylinder 22. A piston is fixedly sleeved on the end of the piston rod 23 inserted into the air inflation cylinder 22. A connecting rod 24 is connected to the other end of the piston rod 23. The connecting rod 24 is in a "U" shape. An electric telescopic rod 25 is installed at the position below the air inflation cylinder 22 on the side surface of the left vertical plate 5. The output shaft of the electric telescopic rod 25 is connected to one end of the connecting rod 24. A pressure sensor 26 is embedded on one side surface of the right abutting block 6. A controller 27 is installed in the middle of the front surface of the right vertical plate 5. The controller 27 is electrically connected to the electric telescopic rod 25. A display screen is embedded on the controller 27. When detecting the common rail pipe, start the first motor 11 to drive the bidirectional screw 12 to rotate. Under the limiting action of the guide rod 9, the two first moving plates 4 move synchronously towards each other, driving the abutting blocks 6 on the two vertical plates 5 to abut against both ends of the common rail pipe to be detected. And the sealing rings 7 on the two abutting blocks 6 abut against the end surface of the common rail pipe to ensure the sealing performance. Then start the electric telescopic rod 25, drive the piston at one end of the piston rod 23 to move towards the side of the common rail pipe in the air inflation cylinder 22 through the connecting rod 24, push the air in the air inflation cylinder 22 into the common rail pipe, detect the internal air pressure of the common rail pipe through the pressure sensor 26, and display the detected air pressure data on the display screen of the controller 27. After a period of time, if the data on the display screen becomes smaller, the airtightness of the common rail pipe is unqualified. If the data on the display screen does not change, the airtightness of the common rail pipe is good.

[0034] See Figure 1 , Figure 5 , Figure 7 and Figure 9 , the lifting structure includes two vertical rods 14 connected to the middle of the upper surface of the bottom plate 13. A lifting pipe 15 is movably sleeved on the top of each vertical rod 14. A lifting block 16 is installed on the top of each lifting pipe 15. A support bar 17 is installed in the middle of the upper surface of the lifting block 16. The upper surface of the support bar 17 is in a concave arc shape;

[0035] The driving structure includes four driving bars 21 respectively connected near the middle under the two first moving plates 4. At the bottom ends of each group of two driving bars 21, a through rod 20 is fixedly passed through. A driving plate 18 is sleeved on each through rod 20. A guiding groove 19 for the through rod 20 to pass through is formed on the driving plate 18. The guiding groove 19 is in a "Z" shape. The two driving plates 18 are respectively connected to the two lifting tubes 15. When the two first moving plates 4 move synchronously towards each other, when the through rod 20 on the driving bar 21 slides in the inclined section of the guiding groove 19 on the driving plate 18, by squeezing the inclined groove wall of the guiding groove 19 by the through rod 20, the driving plate 18 and the lifting tube 15 as a whole are driven to move upward on the vertical rod 14, so as to automatically lift the common rail tubes placed on the two support bars 17 to the detection station for detection work. During this process, one of the driving plates 18 passes through the turntable 28 (the turntable 28 is Figure 2 known to be in the shape of an annular plate), and the other driving plate 18 passes through the outside of the corresponding U-shaped frame 30. There is an avoidance groove between the driving plate 18 and the lifting tube 15 (shown by Figure 9 ), so that the other driving plate 18 can smoothly pass through the outside of the corresponding U-shaped frame 30. Furthermore, the upward movement of the driving plate 18 will not interfere with the components on the turntable 28, and the upward movement of the driving plate 18 will not cross the first moving plate. The driving plate 18 is always located below the first moving plate 4. It is by using the upward movement of the driving plate 18 to drive the support bar 17 to cross the first moving plate 4 and move until it abuts against the position below the abutting block 6.

[0036] See Figures 1 - 4 , the feeding structure includes a rotating groove 39 formed in the two support legs 2 on the right side. A turntable 28 is movably passed through the rotating groove 39. The turntable 28 is in the shape of an annular plate. Near the inner edge on the upper surface of the turntable 28, a plurality of first support seats 29 are installed. At the position corresponding to each first support seat 29 on the side surface of the turntable 28, a U-shaped frame 30 is connected. A second support seat 31 is arranged on the U-shaped frame 30 through a moving structure. The upper surfaces of the first support seat 29 and the second support seat 31 are both concave arc surfaces. An installation plate 32 is bolted to the right edge of the upper surface of the bottom plate 13. A second motor 34 is installed below the installation plate 32. The top end of the output shaft of the second motor 34 is connected with a rotating rod 10 that passes through the installation plate 32. A gear 33 is fixedly sleeved on the top end of the rotating rod 10. The gear 33 is meshed with the teeth on the inner wall of the turntable 28. When the second motor 34 is started and the turntable 28 is driven to rotate on the support leg 2 through the gear 33, the common rail tubes to be detected placed on the first support seat 29 and the second support seat 31 can be automatically conveyed to the position of the support bar 17. In this way, when the support bar 17 moves upward, the common rail tubes placed on the turntable 28 can be smoothly lifted to the detection station for detection;

[0037] The moving structure includes through slots 36 opened on both side surfaces of each U-shaped frame 30. Fixed rods 37 are connected between the two end slot walls of each through slot 36. A second moving plate 38 is movably sleeved on each group of two fixed rods 37. The second support base 31 is installed on the second moving plate 38. Feeding ports 35 are opened at the positions of the turntable 28 between each group of first support bases 29 and U-shaped frames 30.

[0038] A fixed ring 40 is arranged below the turntable 28. The fixed ring 40 is connected to the two support legs 2 on the right side through fixed columns. An annular groove 41 is opened on the upper surface of the fixed ring 40. A protruding portion 42 is arranged at a position of the fixed ring 40 far from the vertical plate 5. A communicating groove 43 is opened on the upper surface of the protruding portion 42. Both ends of the communicating groove 43 communicate with the annular groove 41. A plug rod 44 is connected to the middle of the lower surface of each second moving plate 38. The bottom ends of multiple plug rods 44 are respectively inserted into the annular groove 41 and the communicating groove 43. When the support bar 17 moves downward to drive the detected common rail pipe to be re-placed on the first support base 29 and the second support base 31, the second motor 34 can be started to continue driving the turntable 28 to rotate. When the plug rod 44 on the second moving plate 38 below the corresponding second support base 31 slides in the communicating groove 43, it drives the second moving plate 38 and the second support base 31 as a whole to move toward the side away from the first support base 29. When the second support base 31 disengages from one end of the common rail pipe, the common rail pipe loses support and automatically falls and discharges through the feeding port 35.

[0039] The material receiving structure includes a material receiving frame 45 arranged at the two support legs 2 on the right side. Support plates 47 are respectively connected to the front and rear side edges of one side surface of the material receiving frame 45 close to the support legs 2. Support slots 48 for the two support plates 47 to pass through are respectively opened on the two support legs 2 on the right side. Handles 46 are installed on the front and rear side surfaces of the material receiving frame 45. The falling common rail pipes can be collected by using the material receiving frame 45.

[0040] The implementation principle of a detection device for processing a common rail pipe of an engine in an embodiment of the present invention is as follows: First, place multiple common rail pipes to be detected on the first support seat 29 and the second support seat 31 on the turntable 28. Start the second motor 34, and drive the turntable 28 to rotate in the rotating groove 39 on the support leg 2 through the gear 33. When the turntable 28 conveys the common rail pipe to be detected above the two support bars 17, start the first motor 11 to drive the bidirectional screw rod 12 to rotate. The two first moving plates 4 move synchronously towards each other on the guide rod 9, thereby driving the through rod 20 at the bottom of the driving strip 21 to slide in the guiding groove 19 on the driving plate 18. Through the extrusion of the through rod 20 on the inclined groove wall of the guiding groove 19, the driving plate 18 and the lifting pipe 15 as a whole are pushed to move upward on the vertical rod 14, thereby driving the two support bars 17 to move upward. One of the support bars 17 passes through the corresponding U-shaped frame 30 to support one end of the common rail pipe, and the other support bar 17 passes through the turntable 28 to support the other end of the common rail pipe. As the support bar 17 continues to move upward, the common rail pipe is lifted to the position between the two vertical plates 5. At this time, as the first moving plate 4 continues to move, the through rod 20 slides in the lower horizontal section of the guiding groove 19, so that the support bar 17 and the common rail pipe maintain a constant height. In this way, the continuously moving first moving plate 4 can drive the pressing blocks 6 on the two vertical plates 5 to move and press against the two ends of the common rail pipe. The sealing rings 7 on the pressing blocks 6 are used to press against the two ends of the common rail pipe to ensure the sealing performance. Then, start the electric telescopic rod 25 through the controller 27, drive the piston at one end of the piston rod 23 to move towards the side close to the common rail pipe in the air inflation cylinder 22 through the connecting rod 24, and introduce the air in the air inflation cylinder 22 into the common rail pipe. Use the air pressure sensor 26 on the right pressing block 6 to detect the air pressure in the common rail pipe, and display the air pressure data on the display screen. After a period of time, if the data value on the display screen remains unchanged, the air tightness of the common rail pipe is qualified; if the data value on the display screen becomes smaller, the air tightness of the common rail pipe is unqualified. After the detection, the first motor 11 drives the two first moving plates 4 to move synchronously in opposite directions, and drives the support bar 17 to move downward. The downward moving support bar 17 places the detected common rail pipe back on the first support seat 29 and the second support seat 31. Then start the second motor 34 to continue driving the turntable 28 to rotate. When the insertion rod 44 on the second moving plate 38 below the corresponding second support seat 31 slides in the communication groove 43, it can automatically drive the second support seat 31 to move away from the first support seat 29. When the second support seat 31 disengages from one end of the common rail pipe, the common rail pipe loses support, so that the common rail pipe can be discharged from the blanking port 35 into the collection frame 45 for collection. In this way, the detection work of the common rail pipe can be realized.

[0041] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
