When the anti-loosening property of the fastener is tested, the fastener is first placed in the middle of the stabilizing ring 304, and the hydraulic cylinder 312 is started. After the output end of the hydraulic cylinder 312 is extended, it drives the extrusion clamping block 309 to move toward the middle, and then it can drive the sliding sleeve 308 to slide outside the installation sliding column 305.Thus, the folding driving frame 307 can be driven to fold, and then the other folding driving frames 307 can be driven to fold, so that the other sliding sleeves 308 can be driven to move toward the middle, and then the other extrusion clamping blocks 309 can be driven to move toward the middle through the sliding sleeves 308, so that the extrusion clamping blocks 309 can clamp the fasteners. At this time, the motor 313 is started, and the output end of the motor 313 rotates, so that the gear 314 can be driven to rotate. After the gear 314 rotates, it can drive the ring gear 303 to rotate.

When the sliding sealing cover 406 contacts the fixed baffle 401, a relatively closed space is formed. At this time, due to the start-up of the motor 201, the rotating shaft 405 can be driven to rotate through the belt. After the rotating shaft 405 rotates, it can drive the fan 403 to rotate, and then the fan 403 can be used to generate wind force, thereby simulating a strong wind environment. At this time, the heating wire 404 is started, and the heating wire 404 generates heat after being started, and then hot air can be generated, thereby realizing the anti-loosening detection of fasteners under high temperature conditions.

[0037] A method for detecting a fastener's anti-loosening performance detection device comprises the following steps:

[0038] Step 1: First, the fastener is clamped and fixed by the clamping and rotating mechanism 3, and the motor 201 is started. The motor 201 drives the eccentric wheel 202, the driving rod 203, the push-pull rod 204 and the connecting column 205 to move, so that the fastener clamped on the clamping and rotating mechanism 3 can be vibrated and detected;

[0039] Step 2: The rotation of the eccentric wheel 202 drives the rotating shaft 405 to rotate, and the rotating shaft 405 drives the fan 403 to rotate, so that wind can be generated, and at the same time, the heating wire 404 is started, so that the heating wire 404 can be used to heat the air, and then hot air can be generated;

[0040] Step 3: After the detection is completed, the sliding sealing cover 406 is opened and the fastener is removed from the clamping and rotating mechanism 3 .

[0041] Working principle: When testing the anti-loosening property of fasteners, first place the fasteners in the middle of the stabilizing ring 304, start the hydraulic cylinder 312, and the output end of the hydraulic cylinder 312 extends to drive the extrusion clamping block 309 to move toward the middle, and then drive the sliding sleeve 308 to slide outside the installation sliding column 305, so as to drive the folding driving frame 307 to fold, and then drive several other folding driving frames 307 to fold, so as to drive several other sliding sleeves 308 to move toward the middle, and then drive several other extrusion clamping blocks through the sliding sleeve 308. 309 moves toward the middle, so that the extrusion clamping block 309 can clamp the fastener, and at this time, the motor 313 is started, and the output end of the motor 313 rotates, thereby driving the gear 314 to rotate, and the gear 314 can drive the ring gear 303 to rotate after the rotation, and the installation slide column 305 and the limit slide frame 306 are driven to rotate by the rotation of the ring gear 303, so that the fastener clamped between the extrusion clamping block 309 can be driven to rotate, so that the fastening condition of the fastener in the rotating condition, that is, the anti-loosening property in the rotating condition can be detected;

[0042] The motor 201 is started, and the output end of the motor 201 rotates, driving 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 of the driving rod 203 moves back and forth under the restriction of the push-pull rod 204. The push-pull rod 204 moves back and forth by the driving rod 203 moving back and forth. After the push-pull rod 204 moves back and forth, it can drive the connecting column 205 to move back and forth inside the sliding groove 206, thereby driving the clamping rotation mechanism 3 to move back and forth, and then the tightness of the fastener under vibration can be detected, that is, the anti-loosening property detection of the fastener under vibration can be performed;

[0043] When performing environmental simulation, the handle 6 is pulled, and the handle 6 drives the sliding sealing cover 406 to move toward the fixed baffle 401. When the sliding sealing cover 406 contacts the fixed baffle 401, a relatively closed space is formed. At this time, due to the start-up of the motor 201, the rotating shaft 405 can be driven to rotate through the belt. After the rotating shaft 405 rotates, it can drive the fan 403 to rotate, and then the fan 403 can be used to generate wind force, thereby simulating a strong wind environment. At this time, the heating wire 404 is started, and the heating wire 404 generates heat after being started, and then hot air can be generated, thereby realizing the anti-loosening detection of fasteners under high temperature conditions.

The anti-loosening performance detection device of a fastener according to claim 1, characterized in that: The interior of the sliding groove (206) is connected to the interior of the sliding groove (5), and the side of the eccentric wheel (202) away from the driving rod (203) is rotatably connected to the outside of the base (1).

6. A fastener anti-loosening performance detection device according to claim 1, characterized in that: The installation sliding columns (305) and the position limiting sliding frames (306) are arranged alternately at intervals, and one side of the tooth surface of the gear ring (303) is arranged inside the fixed housing (302).

7. A method for detecting a fastener's anti-loosening performance detection device, according to the fastener's anti-loosening performance detection device according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: First, the fastener is clamped and fixed by the clamping and rotating mechanism (3), and the motor (201) is started. The motor (201) drives the eccentric wheel (202), the driving rod (203), the push-pull rod (204) and the connecting column (205) to move, so that the fastener clamped on the clamping and rotating mechanism (3) can be vibrated and detected; Step 2: The rotation of the eccentric wheel (202) drives the rotating shaft (405) to rotate, and the rotating shaft (405) drives the fan (403) to rotate, thereby generating wind force, and at the same time starting the heating wire (404), so that the heating wire (404) can be used to heat the air, and then generate hot air; Step 3: After the test is completed, the sliding sealing cover (406) is opened and the fastener is removed from the clamping and rotating mechanism (3).
