Description

Technical Field

[0001] This invention relates to the field of aircraft parts processing equipment technology, specifically to an abrasive flow processing device for cleaning sharp edges and burrs in deep hole annular grooves. Background Technology

[0002] Abrasive flow polishing achieves its purpose by using a fluid abrasive material, with a viscoelastic polymer as a carrier and elastic hard abrasive grains as the processing medium, flowing over the surface under pressure. In extrusion abrasive polishing, the interaction between the abrasive grains and the workpiece surface is related to the processing pressure. If the pressure is too low, the abrasive grains only contact the workpiece surface, causing elastic deformation of the workpiece material without generating a cutting action. Increasing the processing pressure causes the contact stress between the abrasive grains and the protrusions on the workpiece surface to reach the fracture limit of the workpiece material, thus removing the protrusions and carrying away the cutting material with the abrasive flow.

[0003] When machining aircraft parts, burrs are removed from the parts using fluid abrasive materials. During the cleaning process, the fluid abrasive materials are usually reused. However, the fluid abrasive materials contain machining debris during the machining process, and existing equipment lacks the ability to handle this debris. If the debris is reused, it can easily cause scratches or even damage to the parts.

[0004] To address the above problems, an abrasive flow machining device for cleaning sharp edges and burrs in deep hole annular grooves is proposed. Summary of the Invention

[0034] III. Operating Process of the Device Processing preparation: Add an appropriate amount of fluid abrasive material into the inner cavity of the storage box 2 through the vertical pipe 21, open the sealing door B13, place the aircraft part to be processed on the six-axis robot 10, and have the six-axis robot 10 clamp and adjust it to the position aligned with the bottom of the jet pipe 6, and close the sealing door B13.

[0035] Parts processing: The pump body A4 is started by the controller 12. The pump body A4 draws the fluid abrasive material in the storage box 2 through the feed pipe 3 and delivers it to the spray pipe 6 through the discharge pipe 5. The spray pipe 6 sprays the material to the deep hole annular groove of the part to clean the sharp edges and burrs. During the processing, the fluid abrasive material is guided to the bottom of the processing box 1 by the guide plate 20.

[0036] Impurity Adsorption: After processing, the drive motor 71 is started, which drives the worm gear 72 to rotate. The worm gear 72 meshes with the worm wheel 73 to rotate, which in turn drives the electromagnetic rod A74 to rotate. The electromagnetic rod A74 drives the rotating ring 75 to rotate, causing the electromagnetic rod B76 to move circumferentially. During rotation, the drive rod 771 contacts the irregular block 773. With the cooperation of the connecting spring 79 and the short rod 78, the electromagnetic rod B76 moves up and down reciprocally. The electromagnetic rods A74 and B76 are energized and generate magnetism, which fully adsorbs ferrous impurities in the fluid grinding material.

[0037] Material recycling: After the impurities are adsorbed, the pump body B25 is started, and the processed fluid grinding material in the processing box 1 is pumped back to the storage box 2 through the bent rod 23 and the connecting pipe 22 to achieve recycling.

[0038] Component Cleaning: When it is necessary to clean the solenoid rods A74 and B76, the servo motor 82 is started. The servo motor 82 drives the threaded rod 83 to rotate. The threaded sleeve 84 moves under the limit of the limit block 841 and the limit rod 842. It drives the hollow ring 86 to move through the connecting rod 85. The cleaning rings A87 and B88 clean the impurities on the outer periphery of the solenoid rods A74 and B76, respectively. At the same time, the threaded sleeve 84 drives the connecting block B91 and the movable block 92 to move. The movable block 92 squeezes the air bag 93. The gas in the air bag 93 is delivered to the solenoid rod A74, the cleaning ring A87 and the cleaning ring B88 through the hose C95, the hose A96 and the hose B97, respectively, to clean the residual impurities in the inner cavity of the cleaning ring.

[0039] Impurity handling: After cleaning, turn off the power to solenoid rods A74 and B76, open the sealing door A11, and remove any loose impurities. If it is necessary to replace the fluid grinding material in storage tank 2, simply open the solenoid valve on the discharge pipe 24 to discharge the old material.

[0040] This embodiment achieves efficient removal of ferrous impurities from fluid grinding materials and automatic cleaning of the device through the synergistic effect of the adsorption component, cleaning component, and jet component, ensuring the quality of parts processing and improving the service life and working efficiency of the device.

[0041] In summary, the working principle of this invention is as follows: An appropriate amount of fluid abrasive material is added to the inner cavity of the storage tank 2 through the vertical pipe 21. The sealing door B13 is opened, and the part to be processed is placed on the six-axis robot arm 10. The six-axis robot arm 10 clamps the part, aligning it with the bottom of the spray pipe 6. Then, the fluid abrasive material in the inner cavity of the storage tank 2 is pumped into the spray pipe 6 and sprayed out through the feed pipe 3 via the pump body A4, allowing for part processing. After processing, the part can be removed. When further processing of the fluid abrasive material is required, the drive motor 71 can be started via the controller 12. The rotation of the power output shaft drives the worm 72, which is fixed to the end of the power output shaft of the drive motor 71, to rotate. This, in turn, causes the worm wheel 73, which meshes with the worm 72, to rotate, thereby causing the electromagnetic rod A74 to rotate. During the rotation of the electromagnetic rod A74, the rotating ring 75, which is fixedly sleeved on the outer circumference of the electromagnetic rod A74, to rotate. This causes several electromagnetic rods B76 to move circumferentially. During the rotation of the rotating ring 75, with the cooperation of the irregular block 773, the ring 772, and the drive rod 771, the electromagnetic rods B76 can move upward and reciprocate, thereby effectively adsorbing ferrous impurities in the fluid abrasive material and improving the effect of processing debris after machining. After adsorbing ferrous impurities from the fluid abrasive material, the fluid abrasive material in the inner cavity of the processing box 1 can be pumped into the inner cavity of the storage box 2 via pump body B25 for reuse. When it is necessary to clean the electromagnetic rods B76 and A74, the servo motor 82 can be started. The rotation of the power output shaft of the servo motor 82 drives the threaded rod 83 fixed to the end of the power output shaft of the servo motor 82 to rotate. The threaded sleeve 84, which is threadedly connected to the outer circumference of the threaded rod 83, can move to one side under the limitation of the limit block 841 and the limit rod 842. Through the connecting rod 85 fixed on the threaded sleeve 84, the hollow ring 86 can be moved to the other side. Through the cleaning ring A87 and the cleaning... Cleaning ring B88 can clean the outer periphery of electromagnetic rods A74 and B76 without manual cleaning, and improves the subsequent adsorption effect of electromagnetic rods A74 and B76. During the movement of threaded rod 83, movable block 92 can move to the other side, thereby squeezing airbag 93, compressing it, and delivering gas to the inner cavity of electromagnetic rod A74 through hose C95. The connection between hose A96 and hose B97 can provide gas to cleaning rings A87 and B88, which can clean impurities located in the inner cavity of cleaning rings A87 and B88 and prevent impurities from falling into the inner cavity of cleaning rings A87 and B88.
