The slide 2 16 indirectly drives the slide 13 to move synchronously. The slide 13 drives the inspection rod 14 to move, so that the inspection rod 14 is in contact with the outer side of the aluminum flange. As the telescopic end of the electric push rod 17 continues to extend, the telescopic end of the telescopic column 18 and the spring 19 contract, so that the inspection rod 14 is elastically fitted with the outer side of the aluminum flange. Then the single chip computer 2 starts the laser rangefinder 15. The laser rangefinder 15 emits a light signal to illuminate the left side of the reflective block and reflects it back to the initial position. According to the propagation speed and time of the light signal, the distance between the two inspection rods 14 is measured. The measurement is carried out, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal. Then the single-chip microcomputer 2 starts the low-speed motor 11 so that its output shaft drives the rotating shaft 2 8 to rotate, and the rotating shaft 2 8 drives the small gear 9 to rotate. The small gear 9 drives the large gear 10 to rotate through the meshing connection, and the large gear 10 indirectly drives the aluminum flange to rotate through the rotating shaft 1 3.

The interior of the slide groove is provided with evenly distributed electric push rods 7, and the input ends of the electric push rods 7 are electrically connected to the output ends of the single-chip computer 2. The telescopic ends of the electric push rods 7 are fixedly connected to the adjacent tightening seat 5. When the roundness of the aluminum flange is inspected, the aluminum flange is first placed on the rotating seat 4 so that the tightening seat 5 is located in the middle of the aluminum flange. Then the single-chip computer 2 starts the electric push rod 7 to shrink its telescopic end, and the aluminum flange is rotated. The corresponding tightening seat 5 moves synchronously along the slide groove away from the center of the device, so that the inner circle of the aluminum flange is contacted and squeezed and fixed by the tightening seat 5. During this process, the single-chip microcomputer 2 starts the pressure sensor 6. The pressure sensor 6 measures the extrusion force between the tightening seat 5 and the aluminum flange through the internal sensor element and transmits it to the single-chip microcomputer 2 in the form of an electrical signal. When the single-chip microcomputer 2 reaches a certain level according to the obtained pressure value, the electric push rod 7 is closed, so that the device can automatically check and fix the roundness of aluminum flanges of different calibers.

[0024] The working principle of the aluminum flange rapid inspection device provided by the utility model is as follows: when the aluminum flange is inspected for roundness, the aluminum flange is first placed on the rotating seat 4 so that the tightening seat 5 is located in the middle of the aluminum flange. Then the single chip microcomputer 2 starts the electric push rod 7 to shrink its telescopic end, driving the corresponding tightening seat 5 to move synchronously away from the center of the device along the slide slot, so that the inner ring of the aluminum flange is contacted and squeezed by the tightening seat 5 to be fixed. In this process, the single chip microcomputer 2 starts the pressure sensor 6, and the pressure sensor 6 measures the extrusion force between the tightening seat 5 and the aluminum flange through the internal sensor element and transmits it to the single chip microcomputer 2 in the form of an electrical signal. When the single chip microcomputer 2 obtains the pressure, the pressure sensor 6 measures the extrusion force between the tightening seat 5 and the aluminum flange through the internal sensor element and transmits it to the single chip microcomputer 2 in the form of an electrical signal. When the pressure value reaches a certain level, the electric push rod 17 is closed, so that the device can automatically check and fix the roundness of aluminum flanges of different calibers. Then, the single-chip computer 2 starts the electric push rod 2 17 so that its telescopic end drives the corresponding slide 2 16 to move along the slide groove 2 close to the center of the device. The slide 2 16 indirectly drives the slide 13 to move synchronously, and the slide 13 drives the inspection rod 14 to move, so that the inspection rod 14 is in contact with the outer side of the aluminum flange. As the telescopic end of the electric push rod 2 17 continues to extend, the telescopic end of the telescopic column 18 and the spring 19 contract, so that the inspection rod 14 elastically fits the outer side of the aluminum flange. Then the single-chip computer 2 starts the laser distance measurement. The laser rangefinder 15 emits a light signal to illuminate the left side of the reflective block and reflects it back to the initial position. The distance between the two inspection rods 14 is measured according to the propagation speed and time of the light signal, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal. Subsequently, the single-chip microcomputer 2 starts the low-speed motor 11 so that its output shaft drives the shaft 2 8 to rotate, the shaft 2 8 drives the small gear 9 to rotate, the small gear 9 drives the large gear 10 to rotate through the meshing connection, and the large gear 10 indirectly drives the aluminum flange to rotate through the shaft 1 3. The laser rangefinder 15 uploads the diameter data measured at each time period during the rotation of the aluminum flange to the single-chip microcomputer 2, and the single-chip microcomputer 2 finally measures the measured diameter data. The maximum value is subtracted from the minimum value, and this error is compared with the standard value to determine whether the roundness of the aluminum flange is qualified. No manual operation is required, it is automatic and convenient to use, and the inspection is fast. If it is unqualified, the single-chip microcomputer 2 starts the alarm 20 to sound to remind the staff that the product roundness is unqualified. In this process, the collector ring can be divided into two parts, one part is the conductive slip ring, and the other part is the connecting contact. The conductive slip ring is fixedly mounted on the rotating shaft 3, and the connecting contact is laid on the upper side of the inspection table 1. The pressure sensor 6 and the electric push rod 7 are electrically connected to the single-chip microcomputer 2 through the collector ring. The collector ring is used to prevent the pressure sensor 6 and the electric push rod 7 from winding during the rotation of the rotating shaft 3.
