Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The invention relates to a rapid detection system for hub defects. (refer to the system for short, see fig. 1), as shown in fig. 1, the overall structure of the system comprises a roller table 1, a hub centering plate 2, a photoelectric sensor 3, a circulating track 4, an intelligent circulating detection vehicle 5, a synchronous belt 51, a gear transmission set 52, a guide wheel 53, a guide wheel bracket 54, a double-shaft stepping motor 55, a turnover motor 56, an electromagnet braking device 57, an expansion link 6, a rotating motor 7, a distance measurement sensor support rod 8, a distance measurement sensor 9, a hub 10, a CCD industrial camera bracket 11, a CCD industrial camera 12, and a connecting rod 13;
the hub centering plates 2 are arranged on the left side and the right side of the roller way 1 and play a role in guiding; the photoelectric sensors 3 are arranged on two sides of a guardrail of the roller way 1 and play a role in position detection; the circulating track 4 is arranged above the roller way 1 and plays a role in guiding; the intelligent circulating detection vehicle 5 is arranged on the circulating track 4; the telescopic rod 6 is arranged below the intelligent circulating detection vehicle 5; the turnover motor 56 is arranged between the telescopic rod 6 and the intelligent cycle detection vehicle 5 and plays a role of rotating the telescopic rod 6; the distance measuring sensor support rod 8 is arranged on one side of the connecting rod 13 and plays a role in fixing and supporting; the distance measuring sensor 9 is arranged on the distance measuring sensor support rod 8; the rotating motor 7 is arranged at the joint of the connecting rod 13 and the distance measuring sensor supporting rod 8 and is used for rotation starting; the CCD industrial camera bracket 11 is arranged on the other side of the connecting rod 13 and plays a role in fixing and supporting; the CCD industrial camera 12 is arranged on the CCD industrial camera bracket 11 and plays a role in detecting defects;
the photoelectric sensor adopts a direct current DC12V and a three-wire NPN type photoelectric sensor.
The range sensor adopts a laser range sensor with the range of 0.05-80m and the precision of +/-1 mm.
The working principle of the rapid detection system for the hub defects is as follows: the distance variation of one circle of rotation around the hub 10 is measured by a laser distance measuring sensor distance measuring principle, and the coaxiality range of the hub 10 is calculated by a computer to judge whether the hub 10 has the defect in the aspect of coaxiality. The CCD industrial camera 12 detects the obvious defects of the inner ring and the outer ring of the hub 10, such as cracks, air holes and shrinkage porosity.
The working principle of the intelligent circulation detection vehicle 5 is as follows: the double-shaft stepping motor 55 drives the synchronous belt 51 to rotate, and when the synchronous belt 51 rotates, the gear transmission set 52 is driven to move and drive the guide wheel 53 to rotate, so that the intelligent circulation detection vehicle 5 is driven to walk on the circulation track 4. The intelligent circulation detection vehicle 5 is controlled by the guide wheel 53 during normal operation, but when the intelligent circulation detection vehicle 5 is in abnormal running, which is unstable or has too high speed, during running, the push-pull rod in the frame-type push-pull electromagnet of the electromagnet braking device 57 is popped up to push against the circulation track 4 to perform emergency stop operation of the intelligent circulation detection vehicle 5.
The invention relates to a quick detection system for hub defects, which comprises the following working procedures: when the hub 10 is placed on the roller table 1 and moved therewith. When passing through the hub centering plate 2, the position of the hub is restrained to move to the position in the middle of the roller table 1. When passing by the photoelectric sensor 3, the photoelectric sensor 3 can detect the position of the hub in preparation for detection. When the detection signals of the photoelectric sensors 3 are received, the three intelligent circulating detection vehicles 5 are ready for detection, the roller way 1 drives the hub 10 to move at a constant speed, when the detection signals of the photoelectric sensors 3 are received and the hub 10 reaches a specified detection position, a fixed time difference exists, and the intelligent circulating detection vehicles 5 can move to the specified detection position of the hub 10 through the circulating track 4 by calculating the time difference. When the intelligent cycle inspection vehicle 5 reaches a predetermined inspection position, the defect inspection work of the hub 10 is started, and the intelligent cycle inspection vehicle 5 starts to move along with the hub 10 at the same speed as the hub 10 and simultaneously starts to extend the telescopic rod 6. When the telescopic rod 6 reaches the specified detection height, the rotating motor 7 drives the distance measuring sensor support rod 8 to start rotating. When the distance measuring sensor 9 detects that the distance from the detection surface of the hub 10 is equal to a set value, the rotation motor 7 stops rotating. When the CCD industrial camera 12 and the distance measuring sensor 9 are both prepared, the revolving motor 56 drives the telescopic rod 6, the connecting rod 13, the distance measuring sensor supporting rod 8, the distance measuring sensor 9, the CCD industrial camera bracket 11, and the CCD industrial camera 12 to start rotating. The defect detection process ends when one revolution around the hub 10 has passed. The rotating motor 7 drives the distance measuring sensor support rod 8 to recover to the original position, and the telescopic rod 6 returns to the original position. The intelligent cycle detection vehicle 5 rotates back to the original detection position through the cycle track 4 to detect the next hub 10. The whole process detection device always moves in a following mode along with the hub 10, and the hub 10 does not need to be fixed into the detection device, so that the effect of quickly detecting defects of the hub is achieved.
Nothing in this specification is said to apply to the prior art.
