The positioning and processing device for inclined oil holes in aerospace fasteners is used for clamping and positioning aerospace fasteners and can open inclined oil holes in aerospace fasteners. In the aerospace field, there is no clear fixed maximum size limit for the diameter of studs with central holes. Generally speaking, according to relevant standards and actual application situations, the common larger diameter bolt fastener specifications can reach M56, and some fastener specifications even require larger sizes. For example, in the key structural connection parts of some large launch vehicles or aerospace vehicles, studs with central holes of larger diameters may be used to meet the requirements of high-strength connection and precise installation and positioning.

A impeller 205 is rotatably connected inside the fixed box 204 which can rotate under the flow of the liquid. The top of the impeller 205 is fixedly connected with a rotating shaft 206. The outside of the rotating shaft 206 is fixedly connected with a stirring rod 207. The rotation of the rotating shaft 206 can drive the stirring rod 207 to rotate. The inner top of the liquid storage barrel 1 is fixedly connected with a fixed ring 208 which can provide an installation space. The inner side of the fixed ring 208 is rotatably connected with a rotating vane ring 209 which can rotate under the action of the liquid flow. The inner side of the rotating vane ring 209 is fixedly connected with a rotating outer sleeve 210. After the rotating vane ring 209 rotates, it can drive the rotating outer sleeve 210 to rotate. After the rotating outer sleeve 210 rotates, it can drive the positioning and clamping mechanism 3 to rotate. The inner side of the rotating outer sleeve 210 is fixedly connected with a rotating ring 211 which provides an installation position. The outside of the fixed box 204 is fixedly connected with a connecting pipe 214 which plays a connecting role. The top of the connecting pipe 214 is fixedly connected with an automatic valve 215 which can control the on-off of the liquid. The top of the automatic valve 215 is fixedly connected to the outside of the fixed ring 208. The outside of the connecting pipe 214 is fixedly connected with an electromagnetic valve 216 which can control the on-off of the liquid. One end of the electromagnetic valve 216 far from the connecting pipe 214 is fixedly connected with a water pipe 217 which can play a connecting role. One end of the water pipe 217 far from the connecting pipe 214 is fixedly connected with a nozzle 218. The bottom of the liquid storage barrel 1 is fixedly connected with a base 8. The connecting pipe 214 penetrates through the outer wall of the liquid storage barrel 1. The nozzle 218 can spray the liquid to cool and wash the fastener 12 being processed and flush the debris into the inside of the liquid storage barrel 1. The top of the rotating shaft 206 is rotatably connected with a stabilizing frame 213 which can maintain the rotational stability of the rotating shaft 206. The outer periphery of the stabilizing frame 213 is fixedly connected to the inner top of the liquid storage barrel 1. The outside of the nozzle 218 is fixedly connected to the outside of the liquid storage barrel 1. The inner side of the rotating ring 211 is fixedly connected with a leakage plate 212 which can prevent the fastener 12 from falling into the inside of the liquid storage barrel 1 before being clamped and positioned.The outer bottom end of the rotating shaft 206 is rotatably connected to the top of the fixed box 204. The stirring rod 207 is arranged inside the liquid storage barrel 1. The water outlet pipe 203 penetrates through the outer wall of the liquid storage barrel 1, and the water suction pipe 202 penetrates through the outer wall of the liquid storage barrel 1. When opening the oil hole of the fastener 12, start the water pump 201. The input end of the water pump 201 sucks out the liquid inside the liquid storage barrel 1 through the water suction pipe 202 and the filtering mechanism 5, and pumps the liquid into the inside of the fixed box 204 through the output end of the water pump 201 and the water outlet pipe 203. At this time, the flow of the liquid can drive the impeller 205 to rotate. After the impeller 205 rotates, it can drive the rotating shaft 206 to rotate. After the rotating shaft 206 rotates, it can drive the stirring rod 207 to rotate. After the stirring rod 207 rotates, it can stir the inside of the liquid storage barrel 1, so as to facilitate the fusion of the water purification agent and the liquid inside the liquid storage barrel 1, accelerate the purification of the liquid inside the liquid storage barrel 1, and then facilitate the secondary utilization of the liquid inside the liquid storage barrel 1. The liquid in the fixed box 204 will enter the inside of the connecting pipe 214. Close the automatic valve 215 and open the solenoid valve 216. At this time, the water flow will enter the inside of the nozzle 218 through the water pipe 217 and be sprayed out by the nozzle 218, so as to cool the fastener 12 with the oil hole opened and wash the cuttings out with the water flow into the inside of the liquid storage barrel 1 to prevent the cuttings from splashing everywhere, and at the same time, the recovery of the cuttings can also be realized. If the solenoid valve 216 is closed and the automatic valve 215 is opened, the water flow can be introduced into the inside of the fixed ring 208, and the flowing water drives the rotating blade ring 209 to rotate. After the rotating blade ring 209 rotates, it can drive the rotating outer sleeve 210 to rotate. After the rotating outer sleeve 210 rotates, it can drive the positioning and clamping mechanism 3 to rotate. After the positioning and clamping mechanism 3 rotates, it can drive the fastener 12 to rotate, so as to facilitate the opening of the inclined oil holes in all directions on the outside of the fastener 12.

[0033] The positioning and clamping mechanism 3 includes a rotating ring plate 301, the bottom of the rotating ring plate 301 is fixedly connected to the top of the rotating ring 211, the top of the rotating ring plate 301 is fixedly connected with a rotating top plate 302, and the rotating ring plate 301 and the rotating top plate 302 cooperate to provide an installation position. A plurality of rotating sleeves 303 are rotatably connected between the rotating ring plate 301 and the rotating top plate 302. The rotating sleeves 303 can provide a sliding position. A sliding rod 304 is slidably connected inside the rotating sleeve 303. The sliding rod 304 can rotate with the rotating sleeve 303 and can clamp and position the fastening member 12, thereby facilitating the processing of the fastening member 12. The top of the rotating outer sleeve 210 is rotatably connected with a hydraulic cylinder 305. The hydraulic cylinder 305 can provide the power for the sliding rod 304 to clamp the fastening member 12. The output end of the hydraulic cylinder 305 is rotatably connected between the rotating ring plate 301 and the rotating top plate 302. The outer sides of the plurality of sliding rods 304 are all rotatably connected to the top of the rotating outer sleeve 210. The fastening member 12 is arranged between the outsides of the plurality of sliding rods 304. Before processing the fastening member 12, it needs to be clamped and positioned. First, place the fastening member 12 in the middle of the rotating ring plate 301, and start the hydraulic cylinder 305. The output end of the hydraulic cylinder 305 extends, so as to drive the rotating ring plate 301 and the rotating top plate 302 to rotate. When the rotating ring plate 301 and the rotating top plate 302 rotate, they can drive the rotating sleeve 303 to rotate. After the rotating sleeve 303 rotates, the sliding rod 304 rotates and inclines, so that the inner sides of the sliding rods 304 gather towards the middle, and then the fastening member 12 can be clamped. And because the inner sides of the sliding rods 304 gather towards the middle simultaneously and at the same distance, the positioning of the fastening member 12 can be realized. At this time, the manipulator 6 can be started to adjust the position of the drilling machine 7, and the drilling machine 7 can be started to drill an inclined oil hole 1204 for the fastening member 12.

The outside of the installation cylinder 401 is fixedly connected to the outer top of the liquid storage barrel 1. A limiting ring 402 is slidably connected inside the installation cylinder 401, and the limiting ring 402 can play a limiting role. A sliding rod 403 is fixedly connected to the bottom of the limiting ring 402. A first spring 404 is fixedly connected between the inner top of the installation cylinder 401 and the inside of the sliding rod 403. The first spring 404 can use its own reaction force to push the sliding rod 403 downward when there is no liquid pressure. A communicating pipe 405 is fixedly connected to the outer bottom end of the installation cylinder 401, and the communicating pipe 405 can play a connecting role. The bottom of the communicating pipe 405 is fixedly connected to the bottom of the fixing ring 208. An exhaust valve 406 is fixedly connected to the top of the installation cylinder 401. A plurality of teeth 407 are fixedly connected to the top of the rotating outer sleeve 210. The cooperation between the teeth 407 and the sliding rod 403 can prevent the rotating outer sleeve 210 from rotating. The bottom of the sliding rod 403 is engaged with the teeth 407. When the liquid just enters the inside of the fixing ring 208, the cooperation between the sliding rod 403 and the teeth 407 can limit the rotation of the rotating outer sleeve 210. When the liquid enters the inside of the installation cylinder 401 through the communicating pipe 405, under the action of the liquid pressure, it can push the limiting ring 402 to move upward and can overcome the elastic force of the first spring 404. When the limiting ring 402 moves upward, it can drive the sliding rod 403 to move upward, and then the sliding rod 403 can be separated from the teeth 407, and then the sliding rod 403 can no longer block the teeth 407. The gas in the space above the installation cylinder 401 can be discharged through the exhaust valve 406. At this time, the stirring rod 207 can drive the rotating outer sleeve 210 to rotate under the action of the flowing liquid. When the rotating outer sleeve 210 does not need to rotate, the water pump 201 is closed. When the water pump 201 no longer pumps the liquid, the liquid will flow downward under the action of gravity and flow out through the communicating pipe 405. At this time, after the limiting ring 402 has no liquid pressure to push it, it can be pushed downward by the elastic force of the first spring 404, and then the sliding rod 403 can be driven to move downward, and then the sliding rod 403 can be engaged with the teeth 407 again, and then the rotation of the rotating outer sleeve 210 can be prevented, maintaining the stability of the rotating outer sleeve 210.

[0035] The filtering mechanism 5 includes a fixed cover 501 which provides installation conditions. The side of the fixed cover 501 away from the fixed box 204 is detachably connected to the side of the water suction pipe 202 away from the water pump 201. An installation frame 502 is fixedly connected to the inner side of the fixed cover 501, and the installation frame 502 can provide an installation space. A fixed cylinder 503 is fixedly connected to the side of the installation frame 502 close to the water suction pipe 202, and the fixed cylinder 503 can provide an installation position. A limiting ring 504 is slidably connected to the inside of the fixed cylinder 503, and the limiting ring 504 has a limiting function. A movable rod 505 is fixedly connected to the side of the limiting ring 504 away from the installation frame 502. A second spring 506 is arranged inside the limiting ring 504. A water passing cover 507 is threadedly connected to the inner side of the fixed cover 501. An installation frame 508 is slidably connected to the inside of the water passing cover 507, and the installation frame 508 provides an installation position. A filter element 509 is arranged inside the installation frame 508, and the filter element 509 can filter the liquid. The movable rod 505 can press against the installation frame 508 to keep the installation frame 508 stable. One end of the second spring 506 is fixedly connected to the inner side of the fixed cylinder 503, and the other end of the second spring 506 is fixedly connected to the inner side of the movable rod 505. The movable rod 505 is in contact with the installation frame 508. When the installation frame 508 and the filter element 509 need to be replaced, the water passing cover 507 can be rotated and unscrewed. At this time, the installation frame 508 can be taken out from the inside of the water passing cover 507, and then a new installation frame 508 and filter element 509 can be put into the inside of the water passing cover 507. At this time, the water passing cover 507 is screwed into the inside of the fixed cover 501 again. When the water passing cover 507 is tightened, the installation frame 508 can press against the movable rod 505, causing the movable rod 505 to move towards the inside of the fixed cylinder 503, and then the movable rod 505 can compress the second spring 506. At this time, the reaction force of the second spring 506 can be used to make the movable rod 505 tightly press against the side of the installation frame 508 close to the installation frame 502, and then the installation frame 508 can be tightly pressed against the inside of the water passing cover 507, realizing the replacement of the installation frame 508.

[0036] Working principle: Before processing the fastener 12, it needs to be clamped and positioned. First, use the manipulator to clamp the fastener 12 and place it in the middle of the rotating ring plate 301. Start the hydraulic cylinder 305, and the output end of the hydraulic cylinder 305 extends, so as to drive the rotating ring plate 301 and the rotating top plate 302 to rotate. When the rotating ring plate 301 and the rotating top plate 302 rotate, they can drive the rotating sleeve 303 to rotate. After the rotating sleeve 303 rotates, the slide bar 304 rotates and tilts, so that the inner sides of the slide bars 304 converge towards the middle, and then the fastener 12 can be clamped. And because the inner sides of the slide bars 304 converge towards the middle simultaneously and at the same distance, the positioning of the fastener 12 can be realized. At this time, the manipulator 6 can be started to adjust the position of the drilling machine 7, and the drilling machine 7 can be started to open the inclined oil hole 1204 for the fastening column 1201, and at the same time, the self-tapping hole 1203 can also be opened at the top of the fastening column 1201, so as to facilitate screwing the self-tapping wire into the self-tapping hole 1203 with an electric screwdriver 13;

[0037] When machining the inclined oil hole 1204 of the fastener 12, start the water pump 201. The input end of the water pump 201 draws the liquid in the liquid storage bucket 1 through the water suction pipe 202 and the filtering mechanism 5, and draws the liquid into the fixed box 204 through the output end of the water pump 201 and the water outlet pipe 203. At this time, the flow of the liquid can drive the impeller 205 to rotate. After the impeller 205 rotates, it can drive the rotating shaft 206 to rotate. After the rotating shaft 206 rotates, it can drive the stirring rod 207 to rotate. After the stirring rod 207 rotates, it can stir the inside of the liquid storage bucket 1, so as to facilitate the fusion of the agent for purifying the water quality and the liquid in the liquid storage bucket 1, accelerate the purification of the liquid in the liquid storage bucket 1, and then facilitate the secondary utilization of the liquid in the liquid storage bucket 1. The liquid in the fixed box 204 will enter the connecting pipe 214. Close the automatic valve 215 and open the solenoid valve 216. At this time, the water flow will enter the inside of the nozzle 218 through the water pipe 217 and be sprayed out by the nozzle 218, so as to cool the fastener 12 with the inclined oil hole 1204 opened, and wash the cuttings out with the water flow into the liquid storage bucket 1 to prevent the cuttings from splashing everywhere, and at the same time, the recovery of the cuttings can also be realized. If the solenoid valve 216 is closed and the automatic valve 215 is opened, the water flow can be introduced into the fixed ring 208, and the water flow drives the rotating vane ring 209 to rotate. After the rotating vane ring 209 rotates, it can drive the rotating outer sleeve 210 to rotate. After the rotating outer sleeve 210 rotates, it can drive the positioning and clamping mechanism 3 to rotate. After the positioning and clamping mechanism 3 rotates, it can drive the fastener 12 to rotate, so as to facilitate the machining of the inclined oil holes 1204 in all directions on the outside of the fastener 12, and then facilitate the connection of multiple mechanical components;

[0038] When the liquid first enters the interior of the fixed ring 208, the rotation of the rotating outer sleeve 210 can be restricted under the cooperation of the sliding rod 403 and the engaging teeth 407. When the liquid enters the interior of the mounting cylinder 401 through the connecting pipe 405, under the action of the liquid pressure, the limiting ring 402 can be pushed upward to move, and can overcome the elastic force of the first spring 404. When the limiting ring 402 moves upward, the sliding rod 403 can be driven to move upward, and then the sliding rod 403 can be separated from the engaging teeth 407, and then the sliding rod 403 can no longer block the engaging teeth 407, and the gas in the space above the mounting cylinder 401 can be discharged through the exhaust valve 406. At this time, the stirring rod 207 can drive the rotating outer sleeve 210 to rotate under the action of the flowing liquid. When the rotating outer sleeve 210 does not need to rotate, the water pump 201 is turned off. When the water pump 201 no longer pumps the liquid, the liquid will flow downward under the action of gravity and flow out through the connecting pipe 405. At this time, after the limiting ring 402 is not pushed by the liquid pressure, it can be pushed by the elastic force of the first spring 404 to drive the sliding rod 403 to move downward, and then the sliding rod 403 can be engaged with the engaging teeth 407 again, and then the rotation of the rotating outer sleeve 210 can be prevented, maintaining the stability of the rotating outer sleeve 210;

[0039] When the mounting frame 508 and the filter element 509 need to be replaced, the water passing cover 507 can be rotated and unscrewed. At this time, the mounting frame 508 can be taken out from the interior of the water passing cover 507, and then the new mounting frame 508 and the filter element 509 can be placed into the interior of the water passing cover 507. At this time, the water passing cover 507 is screwed into the interior of the fixed cover 501 again. When the water passing cover 507 is tightened, the mounting frame 508 can squeeze the movable rod 505, causing the movable rod 505 to move into the interior of the fixed cylinder 503, and then the movable rod 505 can compress the second spring 506. At this time, the reaction force of the second spring 506 can be used to make the movable rod 505 tightly abut against one side of the mounting frame 508 close to the mounting bracket 502, and then the mounting frame 508 can be tightly abutted against the interior of the water passing cover 507, realizing the replacement of the mounting frame 508;

[0040] When collecting the debris inside the liquid filling bucket 1, turn on the faucet 11, and under the filtering action of the filtering mechanism 5, the liquid inside the liquid filling bucket 1 flows out. After the liquid inside the liquid filling bucket 1 is discharged, unscrew the sealing cover 10, and recycle the debris inside the liquid filling bucket 1 through the cleaning port 9.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
