[0002] The high-pressure piping used in hydrogen storage systems has a diameter range of 1 / 4 to 1 / 2 inch. There are two common deburring methods. The first is to manually rotate a handheld deburring tool against the notch of the pipe to remove burrs. Because the operation of handheld tools relies on the operator's skill and experience, tool instability during the deburring process can lead to uneven removal, affecting the surface quality of the high-pressure pipe. Furthermore, deburring with handheld tools typically consumes considerable time and labor, extending production cycles.
[0003] The second method is CNC lathe deburring. This solution is expensive. The clamping tools, cutting tools and processing procedures need to be replaced for pipes of different lengths and diameters. The operation is complicated and not suitable for small batches of products. The surface of the deburred product has a large amount of cutting fluid and oil, which requires additional steps.

DETAILED DESCRIPTION
[0023] Example 1
[0024] There is an electrical cabinet under the assembly base 5, which is equipped with PLC, servo controller and other electrical components. There are two parallel high-pressure pipeline deburring machines on the assembly base 5. The right one is used to remove burrs inside the pipe mouth, such as Figure 1 As shown, the left side is used to remove the burrs on the outside of the pipe. Figure 2As shown. An assembly bracket 4 is provided above the assembly base plate 5. The reducer 2 and the servo motor 3 are fixed to the assembly base plate 5 via the assembly bracket 4. The rotating shaft at the front end of the reducer 2 is connected to the deburring fixture 9 via a key. A deburring tool 13 is provided in the deburring fixture 9. The deburring fixture 9 consists of an upper half shell 10 and a lower half shell 14. The deburring tool 13 of the deburring machine used to remove burrs inside the pipe nozzle has a conical end in contact with the pipe. The deburring tool 13 of the deburring machine used to remove burrs outside the pipe nozzle has a hollow inverted cone in contact with the pipe. A spring 11 is provided between the deburring fixture 9 and the reducer 2. A sensor 8 is provided near the spring 11 and is fixed by a sensor bracket 7. A cylinder fixture 15 is provided at the front end of the deburring tool 13 for clamping the high-pressure pipeline 12. A sensor I 18 is provided next to the deburring tool 13. A dust collecting box 16 is provided below the deburring fixture 9 , and the dust collecting box 16 can collect the fallen burrs and discharge them through a dust collecting pipe.
[0025] The deburring fixture 9 can move axially along the rotating shaft under the action of the spring 11 . Under the action of the reducer 2 and the servo motor 3 , the deburring fixture 9 and the deburring tool 13 rotate along the rotating shaft of the reducer 2 .
[0026] The high pressure pipe deburring machine can be used in automatic mode or manual mode. Figure 3 、 Figure 4 shown.
[0027] Automatic mode: (Switch the working mode to automatic, the cylinder clamp 15 is in automatic state)
[0028] The operator holds the high-pressure pipeline 12 to be processed, inserts it into the left workstation, and slightly pushes the high-pressure pipeline 12 against the deburring tool 13 until the sensor 8 above the spring 11 detects that the deburring fixture 9 has reached the set position.
[0029] At this time, the cylinder clamp 15 starts to clamp the high-pressure pipeline 12. The cylinder clamp 15 and all other moving parts are located inside the safety shield 1 and cannot be touched by the operator, so there is no safety risk.
[0030] After clamping in place, the operator releases the high-pressure pipeline 12, and the servo motor 3 and the reducer 2 drive the deburring fixture 10 and the deburring tool 13 to rotate at a set speed to start deburring.
[0031] After the processing is completed (the processing time can be freely set in automatic mode), the equipment stops rotating, and the cylinder clamp 15 releases the high-pressure pipeline 12 to complete the external burr removal operation.
[0032] The operator takes the part out from the left station and inserts it into the right station, repeating steps 1-4 to complete the internal burr removal operation.
[0033] Manual mode: (Switch the working mode to manual, the cylinder clamp 15 is in the normally open state)
[0034] The operator holds the high-pressure pipeline 12 to be processed, inserts it into the left workstation, and slightly pushes the high-pressure pipeline 12 against the deburring tool 13 until the sensor 8 above the spring 11 detects that the deburring fixture 9 has reached the set position.
[0035] At the same time, the sensor I18 inside the safety shield 1 detects that a high-pressure pipeline 12 is inserted into the equipment for processing (the proximity sensor here only detects metal parts, and the equipment will not start if the operator inserts his finger).
[0036] Then, the servo motor 3 and the reducer 2 drive the deburring fixture 9 and the deburring tool 13 to rotate at a set speed to start deburring. During the rotation process, the operator needs to continue to hold the high-pressure pipeline 12 with a little force.
[0037] In manual mode, the processing time is controlled by the operator (recommended 3 to 8 seconds). After the operation is completed, the operator withdraws the high-pressure pipeline 12 from the left workstation. When the sensor Ⅰ 18 inside the safety shield 1 no longer detects the high-pressure pipeline 12, the servo motor 3 and reducer 2 stop rotating, completing the external burr removal operation.
[0038] The operator holds the high-pressure pipeline 12 to be processed, inserts it into the right workstation, and repeats steps 1 to 4 to complete the internal burr removal operation.
