However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-Figure 11 A fastener locking effect inspection and testing device shown in the figure includes a base 1, a test power mechanism 2 is arranged on the outside of the base 1, an air pressure stabilizing mechanism 3 is arranged on the outside of the base 1, the air pressure stabilizing mechanism 3 is used to stabilize the air pressure, a test mechanism 4 is arranged inside the base 1, the test power mechanism 2 provides power for the test mechanism 4 to test, and a closing mechanism 5 is arranged on one side of the test mechanism 4, and the closing mechanism 5 is used to form a closed space with the test mechanism 4.

[0033] The test power mechanism 2 includes an electric motor 201, which can provide power for inspection and testing. The bottom of the electric motor 201 is fixedly connected to the inside of one side of the base 1. The output end of the electric motor 201 is fixedly connected to an eccentric wheel 202. The side of the eccentric wheel 202 away from the base 1 is rotatably connected to a driving rod 203. The rotation of the eccentric wheel 202 will drive one end of the driving rod 203 to rotate, while the other end will reciprocate. The side of the driving rod 203 away from the eccentric wheel 202 is rotatably connected to a push-pull rod 204. The side of the pull rod 204 away from the eccentric wheel 202 is fixedly connected with a piston 205, and the push-pull rod 204 can drive the piston 205 to reciprocate. The outer side of the base 1 is fixedly connected with a gas generating cylinder 206, and the piston 205 is slidably connected to the inside of the gas generating cylinder 206. The side of the piston 205 away from the push-pull rod 204 is fixedly connected with a push-pull column 207, and the push-pull column 207 can drive the test mechanism 4 to reciprocate. The outside of the gas generating cylinder 206 is fixedly connected with a one-way valve 208. A one-way valve 209 is fixedly connected to the side of the outside away from the one-way valve 1 208. Both the one-way valve 1 208 and the one-way valve 209 can perform one-way ventilation. The motor 201 is started, and the output end of the motor 201 rotates to drive the eccentric wheel 202 to rotate. The eccentric wheel 202 rotates to drive one end of the driving rod 203 to rotate, while the other end moves back and forth. Therefore, the driving rod 203 can drive the push-pull rod 204 to move back and forth, and then drive the piston 205 to move back and forth. The piston 205 moves back and forth, which can drive the push-pull column 207 to move back and forth, thereby driving the test mechanism 4 to perform reciprocating motion. When the piston 205 moves toward the direction of the eccentric wheel 202, the one-way valve 1 208 is closed and the one-way valve 209 is opened, so that the air in one of the air pressure stabilizing mechanisms 3 can be extracted. When the piston 205 moves toward the end away from the eccentric wheel 202, the one-way valve 1 208 is opened and the one-way valve 209 is closed, and then the air can be exhausted to the other air pressure stabilizing mechanism 3.

[0034] The air pressure stabilizing mechanism 3 includes two pressure stabilizing tanks 301, which provide a space for gas to flow, thereby stabilizing the air pressure. The exteriors of the two pressure stabilizing tanks 301 are fixedly connected to the exterior of the base 1, and the tops of the pressure stabilizing tanks 301 are fixedly connected with electric valves 302, which can start the control switch, and then can control the gas to be discharged or sucked into the interior of the pressure stabilizing tanks 301. The tops of the electric valves 302 are fixedly connected with hoses 303, which serve as a connection. The exteriors of the pressure stabilizing tanks 301 are fixedly connected with mounting shells 304, and the interior of the mounting shells 304 is provided with springs 305. The interior of the mounting shells 304 is slidably connected with air hole disks 306, and the air hole disks 306 are fixedly connected to the side away from the pressure stabilizing tanks 301. A connecting rod 307 is connected, and a plug 308 is fixedly connected to the side of the connecting rod 307 away from the air hole disk 306. An air outlet pipe 309 is fixedly connected to the outside of one of the pressure-stabilizing tanks 301, and the bottom of the air outlet pipe 309 is fixedly connected to the top of the one-way valve 208. An exhaust pipe 310 is fixedly connected to the outside of the other pressure-stabilizing tank 301, and the top of the exhaust pipe 310 is fixedly connected to the bottom of the one-way valve 209. One end of the spring 1 305 is fixedly connected to the side of the air hole disk 306 away from the plug 308, and the other end of the spring 1 305 is fixedly connected to the inside of the mounting shell 304. When exhausting, the gas inside one of the pressure-stabilizing tanks 301 is extracted through the exhaust pipe 310, and when the electric When the movable valve 302 is opened, the gas inside the test mechanism 4 can be extracted. When the gas is extracted to a certain extent, in order not to affect the movement of the piston 205 inside the gas generating cylinder 206, the plug 308 is driven to move in the direction of one of the pressure-stabilizing tanks 301 under the action of the suction force of one of the pressure-stabilizing tanks 301. When the plug 308 moves out of the interior of the mounting shell 304, the gas enters the interior of the mounting shell 304 and enters the interior of one of the pressure-stabilizing tanks 301 through the holes on the air hole disk 306. When the air pressure is restored to some extent, the air hole disk 306 is moved again in the direction away from one of the pressure-stabilizing tanks 301 under the action of the spring 1 305, so that the plug 308 can be driven to reset through the connecting rod 307. , and is blocked again inside the mounting shell 304. When the interior of the test mechanism 4 requires high pressure, the gas is passed into the interior of another pressure-stabilizing tank 301 through the gas outlet pipe 309. At this time, another electric valve 302 is opened, so that the gas can be filled into the interior of the test mechanism 4 using the hose 303. When the air pressure inside the other pressure-stabilizing tank 301 is too high, the gas will push the plug 308 to move outward. When the plug 308 moves out of the mounting shell 304, the gas inside the other pressure-stabilizing tank 301 will be discharged to the outside. After the gas is discharged, the air hole disk 306 will be pulled back by the action of the spring 1 305, and then the plug 308 can be pulled back by the connecting rod 307 and blocked again inside the mounting shell 304.

A fitting groove 420 is provided on the outer side of the base 1. The plug 308 is slidably connected to the inside of the side of the mounting shell 304 away from the pressure-stabilizing tank 301. The interior of the spring 1 305 is connected to the interior of the pressure-stabilizing tank 301. The ends of the two hoses 303 away from the electric valve 302 are respectively fixedly connected to the two ends of the three-way pipe 407.

When the push-pull column 207 moves back and forth, it can drive the sliding plate 401 to move back and forth. When the sliding plate 401 moves back and forth, the impact force on the fastener can be tested. At the same time, when the sliding plate 4 When 01 moves back and forth, the shaking occurs, which can drive the moving rod 406 to move toward the inside of the rotating cylinder 403, and the vibration spring 404 will give the limit plate 405 an upward reaction force, so that the moving rod 406 can be pushed upward, thereby realizing the back and forth movement of the moving rod 406, and then the installation cylinder 402 can be shaken quickly, so as to simulate the vibration environment.

At this time, the sealing cover 501 is pushed into the interior of the installation cylinder 402, and then the clamping ring 510 can be driven to move in the direction of the installation cylinder 402. Since the head of the locking arm 508 is a curved surface, it is squeezed by the curved surface of the clamping ring 510, and then the head of the locking arm 508 can be rotated in the direction away from the installation cylinder 402. When the clamping ring 510 moves to the inner side of the head of the locking arm 508, the spring piece 509 will push the tail of the locking arm 508 to rotate in the direction away from the installation cylinder 402, and the head of the locking arm 508 can be rotated in the direction of the installation cylinder 402.Then, the head of the locking arm 508 can be locked on the locking ring 510, so that the fastener can be inserted and the installation tube 402 can be sealed.

[0037] Working principle: When testing, first start the motor 201. After the output end of the motor 201 rotates, it can drive the eccentric wheel 202 to rotate. After the eccentric wheel 202 rotates, it can drive one end of the driving rod 203 to rotate, and the other end will move back and forth. Therefore, the push-pull rod 204 can be driven to move back and forth through the driving rod 203, and then the piston 205 can be driven to move back and forth. The back and forth movement of the piston 205 can drive the push-pull column 207 to move back and forth, so as to drive the testing mechanism 4 to reciprocate. When the piston 205 moves in the direction of the eccentric wheel 202, the one-way valve 1 208 is closed and the one-way valve 209 is opened, so that the air in one of the air pressure stabilizing mechanisms 3 can be extracted. When the piston 205 moves toward the end away from the eccentric wheel 202, the one-way valve 1 208 is opened, and the one-way valve 209 is closed, and then the air can be exhausted to the other air pressure stabilizing mechanism 3.

[0038] When the air is pumped out, the gas inside one of the pressure-stabilizing tanks 301 is pumped out through the air pumping pipe 310, and when the electric valve 302 on the top of one of the pressure-stabilizing tanks 301 is opened, the gas inside the test mechanism 4 can be pumped out. When the gas is pumped to a certain extent, in order not to affect the movement of the piston 205 inside the gas generating cylinder 206, the plug 308 is driven to move toward one of the pressure-stabilizing tanks 301 under the action of the suction force of one of the pressure-stabilizing tanks 301. When the plug 308 moves out of the interior of the mounting shell 304, the gas enters the interior of the mounting shell 304 and enters the interior of one of the pressure-stabilizing tanks 301 through the holes on the air hole disk 306. When the air pressure is restored to a certain extent, the air hole disk 306 is moved again away from one of the pressure-stabilizing tanks 301 under the action of the spring 1 305. When the inside of the test mechanism 4 needs high pressure, the gas is passed into the inside of another pressure-stabilizing tank 301 through the gas outlet pipe 309. At this time, another electric valve 302 is opened, so that the gas can be filled into the inside of the test mechanism 4 by the hose 303. When the gas pressure inside the other pressure-stabilizing tank 301 is too high, the gas will push the plug 308 to move outward. When the plug 308 moves out of the outside of the installation shell 304, the gas inside the other pressure-stabilizing tank 301 will be discharged to the outside. When the gas is discharged, the air hole disk 306 will be pulled back by the action of the spring 1 305, and then the plug 308 can be pulled back by the connecting rod 307 to block the inside of the installation shell 304 again.

[0039] When the push-pull column 207 moves back and forth, it can drive the sliding plate 401 to move back and forth. When the sliding plate 401 moves back and forth, the impact force on the fastener can be tested. At the same time, when the sliding plate 401 moves back and forth, it shakes, so it can drive the moving rod 406 to move inside the rotating cylinder 403, and the vibration spring 404 will give the limit plate 405 an upward reaction force, so that the moving rod 406 can be pushed upward, thereby achieving the moving rod 406 When the gas in the installation tube 402 is pumped out, a low-pressure environment can be simulated. When the gas in the installation tube 402 is filled, a high-pressure environment can be simulated. When switching between low-pressure and high-pressure environments, the internal air pressure of the installation tube 402 needs to be balanced with the external air pressure. When the air pressure is balanced, the handle 419 is rotated, which in turn drives the pressing rod 413 to rotate, and at this time, the limit slot 402 can be driven to rotate. 14 is rotated, and then the limit block 410 can be rotated from the horizontal groove position of the limit groove 414 to the vertical groove position of the limit groove 414, and then the pressing rod 413 can be pressed in the direction of the installation cylinder 402, so that the installation column 415 drives the sliding plug 416 to leave the exhaust pipe 417. At this time, the gas inside the installation cylinder 402 will be discharged or inhaled through the vent hole 418. When the air pressure inside the installation cylinder 402 is balanced, the handle 419 can be released. At this time, under the action of the spring 411 The vent limit plate 412 is driven downward to move away from the installation cylinder 402, so that the sliding plug 416 can be blocked in the exhaust pipe 417 again to seal the installation cylinder 402. At this time, the reverse handle 419 drives the pressing rod 413 to rotate, so that the limit groove 414 rotates, and the limit block 410 is moved to the horizontal groove position of the limit groove 414, so that the air pressure inside the installation cylinder 402 is prevented from being too small, causing the sliding plug 416 to be pushed or sucked to slide;

[0040] When inserting the fastener, first press the tail ends of the multiple locking arms 508 in the direction of the installation cylinder 402, so that the heads of the locking arms 508 can be lifted, and then the snap ring 510 can be loosened, and the limiting ring 506 and the tightening ring 507 are pushed to the outside of the installation cover 504 under the reaction force of the extrusion spring 505, and then the sealing cover 501 can be pushed out of the installation cover 504. At this time, the sealing cover 501 is pulled to the side away from the installation cylinder 402 by the handle 511, and then the mechanical arm 502 and the limiting frame 503 can be pulled out of the installation cylinder 402, and the fastener is placed in the clamping position of the mechanical arm 502. The mechanical arm 502 is started so that the fastener can be clamped. The sealing cover 501 is pushed toward the interior of the mounting tube 402, and then the retaining ring 510 can be driven to move toward the mounting tube 402. Since the head of the locking arm 508 is a curved surface, it is squeezed by the curved surface of the retaining ring 510, and then the head of the locking arm 508 can be rotated away from the mounting tube 402. When the retaining ring 510 moves to the inner side of the head of the locking arm 508, the tail of the locking arm 508 is pushed to rotate away from the mounting tube 402 under the action of the spring piece 509, and the head of the locking arm 508 can be rotated toward the mounting tube 402, and then the head of the locking arm 508 can be engaged with the retaining ring 510, thereby realizing the insertion of the fastener and sealing the mounting tube 402.
