Description

Technical Field

[0001] The invention relates to the technical field of polishing devices, in particular to a polishing device for producing aviation rivets. Background Art

[0002] Aviation rivets are high-precision fasteners specially designed for use in aircraft and other aerospace structures. They can provide reliable connections in environments of high stress, vibration, and extreme temperature changes to ensure the safety and durability of aircraft. Polishing is an important process in the production of aviation rivets. It can improve the quality of the rivet surface and remove defects such as burrs and scratches, thereby ensuring the aesthetics and performance of the rivets. In order to improve the polishing efficiency of aviation rivets, most rivet polishing machines are used for polishing.

[0003] However, the existing aviation rivet polishing device still has certain defects when in use. For example, when polishing the rivet, it is necessary to put the polishing liquid or water, polishing sand and the rivet into the polishing device, and then stir the rivet and the polishing sand to make the two rub, so as to remove the burrs on the rivet. Therefore, when the rivet is polished and taken out, a large amount of polishing sand is usually adhered to the surface of the rivet. These residual polishing sands often need to be rinsed with clean water separately, and in order to facilitate subsequent inspection and packaging, it is also necessary to prepare drying equipment to dry the water on the surface, which will have a certain impact on production efficiency.

[0037] During use, the user can introduce the polishing liquid, polishing sand and rivets into the polishing chamber 101 through the feed hopper 102, and then start the servo drive motor 103. The servo drive motor 103 drives multiple stirring paddles 105 and scrapers 104 to rotate, stir the polishing liquid, polishing sand and rivets, and make the polishing sand and rivets rub against each other to polish the rivets. At this time, the polishing liquid can dissipate the heat generated by the friction between the rivets and the polishing sand.

[0038] When the rivet is polished, the scraper 104 is kept rotating and the servo motor 108 is started. The servo motor 108 rotates the rotating plate 304 to move the two connecting rods 301 to the bottom of the two coarse filter screens 303. At this time, the polishing liquid will flow into the separation box 401 through the coarse filter screen 303 and the separation port 307, and flow into the temporary storage chamber 505 through the fine filter screen 402 and the guide tube 504 at the bottom of the separation box 401, while the polishing sand will fall into the separation box 401 through the two coarse filter screens 303 and the separation port 307 to separate the rivet and the polishing sand, and make the rivet stay on the support plate 302. In addition, the rotation of the scraper 104 can sweep the polishing sand on the support plate 302 to the top of the coarse filter screen 303 and prevent the polishing sand from clogging the mesh of the coarse filter screen 303.

[0039] Furthermore, when the polishing sand falls into the separation box 401, the motor 405 is started to intermittently rotate the auger 406 to move the polishing sand along the auger 406, thereby moving the polishing sand to the sand discharge port 403 and falling into the collection chamber 404. At this time, the auger 406 can prevent the polishing sand from accumulating above the fine filter 402, causing the fine filter 402 to be blocked, so as to separate and recover the polishing liquid and polishing sand.

[0040] See also Figure 3 , Figure 7 , Figure 8 and Fig.12 In the figure, a suction pump 503 is provided inside the polishing box 1, a separation box 5 is provided at the bottom of the cover plate 3, and a plurality of nozzles 501 are provided at the bottom of the separation box 5; a suction pipe 506 is connected to one side of the suction pump 503, and a discharge hose 502 is connected to one side of the suction pump 503, and the discharge hose 502 is connected to the separation box 5. When in use, the suction pump 503 is turned on to extract the polishing liquid recovered from the temporary storage chamber 505, so that the polishing liquid enters the separation box 5 through the suction pipe 506 and the discharge hose 502, and is sprayed from the discharge hose 502 onto the rivet on the top of the support plate 302. At this time, the scraper 104 is slowly rotated by the servo drive motor 103, so that the polishing sand remaining on the rivet can be washed to ensure the cleanliness of the surface of the rivet.

[0041] See also Figure 2 , Fig. 9 , Fig.10 , Fig.11 and Fig.13In the embodiment, two heating rods 808 are arranged inside the drying chamber 9, a servo motor 8 is arranged on the top of the polishing box 1, a mounting plate 805 is arranged inside the drying chamber 9, a rotating rod 803 is arranged inside the drying chamber 9, one end of the rotating rod 803 is connected to one side of the inner wall of the drying chamber 9 through a bearing, a cylinder 806 is arranged on the outside of the rotating rod 803, and a plurality of fan blades 807 are arranged on the outside of the cylinder 806, a bevel gear 707 is arranged inside the drying chamber 9, a reciprocating screw rod 706 is connected to the bottom of the bevel gear 707, and the bottom end of the reciprocating screw rod 706 is connected to the bottom of the inner wall of the drying chamber 9 through a bearing, a pressing plate 705 is arranged inside the drying chamber 9, a ventilation net 802 is arranged on one side of the polishing box 1, an air inlet net 804 is arranged between the drying chamber 9 and the polishing chamber 101, a hydraulic chamber 7 is opened inside the polishing box 1, an electromagnet 703 is arranged at the bottom of the inner wall of the drying chamber 9, an extrusion piston 701 is arranged inside the hydraulic chamber 7, and a temporary storage chamber 505 is arranged inside the polishing box 1; servo motor 8 is connected to an active bevel gear 801 at the bottom through a rotating shaft, a driven bevel gear 809 is arranged on the outside of the rotating rod 803, and the active bevel gear 801 is meshed with the driven bevel gear 809, and the bevel gear 707 is meshed with the driven bevel gear 809; a threaded hole matching the reciprocating screw 706 is provided on the top of the pressure plate 705, a connecting rod 702 is connected to the top of the extrusion piston 701, and an iron block 704 is arranged on the top of the connecting rod 702; a piston 606 is arranged inside the hydraulic chamber 7, a fixed connecting rod 605 is connected to the bottom of the piston 606, a spring 607 is sleeved on the outside of the fixed connecting rod 605, a contraction groove 604 is arranged below the hydraulic chamber 7, the bottom end of the fixed connecting rod 605 extends into the contraction groove 604, and is connected to a blocking plate 6, a lifting groove 603 is arranged at the bottom of the inner wall of the temporary storage chamber 505, and sealing rings 601 are arranged inside the lifting groove 603 and the contraction groove 604, and a drainage port 602 is arranged on one side of the blocking plate 6.

[0042] After the rivets are flushed, the pump 503 is turned off, and the two electric telescopic rods 201 are controlled to drive the cover plate 3 to rise, and the rivets on the support plate 302 are moved to the side of the air inlet net 804, and then the servo motor 8 is started and turned on. The driven bevel gear 809, the bevel gear 707 and the rotating rod 803 are rotated by the servo motor 8, wherein the rotating rod 803 can drive the cylinder 806 and the fan blade 807 to rotate. At this time, in conjunction with the heating rod 808, warm air can be produced to blow toward the polishing chamber 101 to dry the rivets on the support plate 302. While the rotating rod 803 drives the bevel gear 707 to rotate, it will drive the reciprocating screw rod 706 to rotate, so that the pressing plate 705 moves downward. It moves up and down along the reciprocating screw rod 706, and the electromagnet 703 is turned on at this time. When the pressure plate 705 moves downward, the iron block 704 will be squeezed, thereby driving the connecting rod 702 and the squeezing piston 701 to squeeze the hydraulic oil inside the hydraulic chamber 7, and then the piston 606 is driven by the hydraulic oil to squeeze the spring 607, and the fixed connecting rod 605 and the blocking plate 6 move downward, so that the blocking plate 6 moves into the bottom of the lifting groove 603, and the drain port 602 moves into the temporary storage chamber 505, and then the polishing liquid inside the temporary storage chamber 505 is discharged. When the rivet is dried, the two electric telescopic rods 201 are controlled to rise, driving the rivet on the top of the support plate 302 to move out of the polishing chamber 101, so that the rivet can be taken out.

[0043] Here’s how it works: During use, the user can introduce the polishing liquid, polishing sand and rivets into the polishing chamber 101 through the feed hopper 102, and then start the servo drive motor 103. The servo drive motor 103 drives multiple stirring paddles 105 and scrapers 104 to rotate, stir the polishing liquid, polishing sand and rivets, and make the polishing sand and rivets rub against each other to polish the rivets. At this time, the polishing liquid can dissipate the heat generated by the friction between the rivets and the polishing sand.

[0044] When the rivet is polished, the scraper 104 is kept rotating and the servo motor 108 is started. The servo motor 108 rotates the rotating plate 304 to move the two connecting rods 301 to the bottom of the two coarse filter screens 303. At this time, the polishing liquid will flow into the separation box 401 through the coarse filter screen 303 and the separation port 307, and flow into the temporary storage chamber 505 through the fine filter screen 402 and the guide tube 504 at the bottom of the separation box 401, while the polishing sand will fall into the separation box 401 through the two coarse filter screens 303 and the separation port 307 to separate the rivet and the polishing sand, and make the rivet stay on the support plate 302. In addition, the rotation of the scraper 104 can sweep the polishing sand on the support plate 302 to the top of the coarse filter screen 303 and prevent the polishing sand from clogging the mesh of the coarse filter screen 303.

[0045] Furthermore, when the polishing sand falls into the separation box 401, the motor 405 is started to intermittently rotate the auger 406 to move the polishing sand along the auger 406, thereby moving the polishing sand to the sand discharge port 403 and falling into the collection chamber 404. At this time, the auger 406 can prevent the polishing sand from accumulating above the fine filter 402, causing the fine filter 402 to be blocked, so as to separate and recover the polishing liquid and polishing sand.

[0046] When the rivets are separated, the extraction pump 503 is turned on to extract the polishing liquid recovered from the temporary storage chamber 505, so that the polishing liquid enters the separation box 5 through the extraction pipe 506 and the discharge hose 502, and is sprayed from the discharge hose 502 onto the rivet on the top of the support plate 302. At this time, the scraper 104 is slowly rotated by the servo drive motor 103 to wash away the polishing sand remaining on the rivet, thereby ensuring the cleanliness of the surface of the rivet.

[0047] Furthermore, after the rivet flushing is completed, the material pump 503 is turned off, and the two electric telescopic rods 201 are controlled to drive the cover plate 3 to rise, and the rivets on the support plate 302 are moved to the side of the air inlet net 804, and then the servo motor 8 is started and turned on, and the driven bevel gear 809, the bevel gear 707 and the rotating rod 803 are rotated by the servo motor 8, wherein the rotating rod 803 can drive the cylinder 806 and the fan blade 807 to rotate, and at this time, in conjunction with the heating rod 808, warm air can be produced to blow toward the polishing chamber 101 to dry the rivets on the support plate 302, and while the rotating rod 803 drives the bevel gear 707 to rotate, it will drive the reciprocating screw rod 706 to rotate, so that the pressing plate 705 moves downward. It moves up and down along the reciprocating screw rod 706, and the electromagnet 703 is turned on at this time. When the pressure plate 705 moves downward, the iron block 704 will be squeezed, thereby driving the connecting rod 702 and the squeezing piston 701 to squeeze the hydraulic oil inside the hydraulic chamber 7, and then the piston 606 is driven by the hydraulic oil to squeeze the spring 607, and the fixed connecting rod 605 and the blocking plate 6 move downward, so that the blocking plate 6 moves into the bottom of the lifting groove 603, and the drain port 602 moves into the temporary storage chamber 505, and then the polishing liquid inside the temporary storage chamber 505 is discharged. When the rivet is dried, the two electric telescopic rods 201 are controlled to rise, driving the rivet on the top of the support plate 302 to move out of the polishing chamber 101, so that the rivet can be taken out.
