Description
Technical Field
[0001] The present invention relates to the technical field of coaxiality detection, and in particular to a device and method for detecting the coaxiality of both end shafts of a slender shaft. Background Art
[0002] Coaxiality is the positioning tolerance, and the theoretical correct position is the reference axis. Since the different points of the measured axis relative to the reference axis may appear in all directions in space, its tolerance zone is a cylinder with the reference axis as the axis, and the tolerance value is the diameter of the cylinder. The symbol "Φ" is always added before the tolerance value.
[0003] Coaxiality tolerance: It is used to control the degree of misalignment between the measured axis and the reference axis, which should be coaxial in theory.
[0004] Coaxiality error: the change in the position of the measured axis relative to the reference axis.
[0005] To put it simply, it means that there is a degree of deviation between the two axes on the part that are required to be on the same straight line. The deviation between the two axes is usually a combination of three situations (the reference axis is an ideal straight line) - bending of the measured axis, tilt of the measured axis and offset of the measured axis.
[0006] The existing coaxiality detection device has a single detection method during detection, so the data obtained during detection is relatively single and the detection effect is poor. In addition, when performing coaxiality detection, the detection device mostly detects the end shafts separately. Therefore, when performing detection, it is necessary to perform detection operations on both sides of a single shaft rod, which affects the detection efficiency and the equipment is not effective.

[0045] A method for detecting the coaxiality of the two ends of a slender shaft, using the above-mentioned device for detecting the coaxiality of the two ends of a slender shaft, comprises the following steps:
[0046] Step 1: When in use, start the driving motor 301, drive the shaft member 316 to rotate through the driving motor 301, and drive the driving gear 313 to rotate through the shaft member 316. Since the driving gear 313 is meshed with the driven gear 314, the two shaft members 316 simultaneously drive the two winding wheels 315 to rotate, so as to adjust the connecting cable 310, and deform the return spring rod 302 to adjust the position of the movable seat 303, until the distance between the two movable seats 303 is consistent with the distance between the bearings of the long shaft body 4, and the long shaft body 4 is set on the two The center of the long axis body 4 is set inside the installation frame 501, and the electric telescopic rod 511 is started, and the multiple clamping plate frames 510 are driven to move by the electric telescopic rod 511 until the clamping plate frames 510 drive the resistance member 509 to clamp the long axis body 4, and the electric push rod 513 is started at the same time, and the position of the fixed seat 503 is adjusted by the electric push rod 513, and the air pump 507 is started, and the airbag member 504 is inflated by the air pump 507 until the airbag member 504 contacts the long axis body 4 to provide auxiliary support for it, so as to complete the clamping and fixing operation;
[0047] Step 2: During cleaning, start the electric rod 701, and drive the movable bracket 703 to move through the electric rod 701, thereby driving the cleaning pump 711 and the air bin 705 to move, so that the cleaning port 704 on the air bin 705 moves through the surface of the long axis body 4 and the surface of the rotating wheel 305. During this process, the cleaning pump 711 is started, and the cleaning pump 711 sucks air into the air inlet hood 708, and then enters the filter tube 706, and is cleaned through the filter frame 715 inside it. After that, the gas enters the exhaust hood 710, and then enters the cleaning pump 711, and is further transported to the inside of the air bin 705, so as to be discharged through the cleaning port 704 for cleaning. During cleaning, the staff cooperates to rotate the rotating wheel 305 and the long axis body 4 to clean until the cleaning is completed.
[0048] Step 3: During the detection, start the electric rod 304, which drives the rotating wheel 305 to contact the long shaft body 4 again, and then start the stepper motor 309, which drives the connecting shaft 330, the connecting sleeve rod 311 and the movable inner rod 312 to rotate, so that the two detection arc rods 318 drive the detector body 317 to move to the detection position, and then start the power motor 319, which drives the screw rod 320 to move, so that the movable rod frame 323 drives the detection contact pin 329 to contact the two ends of the long shaft body 4, and then start the motor 2 506, which drives the rotating gear 505 to rotate. The rotating gear 505 is meshed with the gear ring frame 502, thereby driving the gear ring frame 502 to rotate, and then rotating the long axis body 4 for detection. During detection, the detector body 317 obtains data, and at the same time, the detection probe 329 will draw wire loops at both ends of the long axis body 4. At this time, the motor 324 is started, and the motor 324 drives the transmission gear 325 to rotate. Since the transmission gear 325 is meshed with the gear ring 326, it drives the measuring device 328 to rotate, so as to measure the distance between the edge of the wire loop and the end edge of the long axis body 4, and obtain data to complete the detection. After that, the obtained data is collected by the data acquisition device to complete the coaxiality detection operation.
