Detecting the aperture size of the inner hole of the worm wheel 6
The inner hole detection sensor 512 is started to work, the third linear module 511 drives the probe bracket 513 to horizontally move for a certain distance, so that the inner hole detection sensor 512 on the probe bracket 513 extends into the inner hole of the worm wheel 6, and the third linear module 511 stops working. Because the detection position of the inner hole detection sensor 512 is located at the axis position of the worm wheel 6, the distance between the detection position and the hole wall of the inner hole is a constant value, and the inner hole detection sensor 512 performs sampling point detection on the surface of the inner hole of the worm wheel 6 at a constant frequency in the process that the worm wheel 6 rotates at a certain rotating speed. The collected data points are transmitted to data analysis software of a computer, and a radius size distribution curve of an inner hole of the worm wheel 6 can be automatically fitted. When the inner hole is a round hole, the curve fitted by the acquisition points is an approximate horizontal line, and when the inner hole is a spline hole, the curve fitted by the acquisition points is an approximate rectangular square wave. Meanwhile, as the rotating speed of the worm wheel 6 is fixed and the detection frequency of the inner hole detection sensor 512 is fixed, the large-diameter arc length and the small-diameter arc length of the inner spline hole can be automatically calculated through software by counting the rotating speed of the worm wheel 6 and the collection points in the single large-diameter arc length range and the single small-diameter arc length range of the inner spline hole, so that the size information of the inner spline hole can be obtained.
After the detection is completed, the inner hole detection sensor 512 is turned off, and the third linear module is started to rotate in the reverse direction, so that the components of the inner hole detection mechanism 51 are reset.
② dimension detection of 6-tooth profile of worm wheel
The first tooth profile detection sensor 535 and the second tooth profile detection sensor 533 are started to work, the first mounting plate 534 is driven to horizontally move for a preset distance through the fourth linear module 531, the detection position of the first tooth profile detection sensor 535 reaches the middle surface position of the worm wheel 6 in a clamping state, the second mounting plate 536 is driven to horizontally move for a preset distance through the fifth linear module 532, the second tooth profile detection sensor 533 reaches the detection position deviated from the detection position of the first tooth profile detection sensor 535 by a certain distance, the worm wheel 6 rotates at a certain rotating speed, and the first tooth profile detection sensor 535 and the second tooth profile detection sensor 533 respectively perform sampling point detection on two sampling positions of the outer tooth surface at a constant frequency. By the data acquisition, analysis and processing method, the tooth profile of the middle plane of the worm wheel 6 and the tooth profile of the other detection position can be respectively fitted. Since the distances between the first tooth profile detection sensor 535 and the second tooth profile detection sensor 533 in the transverse direction and the longitudinal direction are known, the corresponding external tooth helix angle can be calculated by fitting the tooth profile of the middle plane of the worm wheel 6 and the tooth profile of the other detection position.
After the detection is completed, the first tooth profile detecting sensor 535 and the second tooth profile detecting sensor 533 are turned off, and the fourth linear module 531 and the fifth linear module 532 are turned on to rotate in opposite directions, so that the components of the tooth profile detecting mechanism 53 are reset.
③ thickness dimension of the worm wheel 6
When the detection of the inner hole and the outer tooth surface of the worm wheel 6 is completed, the rotation driving motor 413 is turned off to stop the rotation of the worm wheel 6. The first thickness detection sensor 523 and the second thickness detection sensor 524 are turned on, and the first linear module 411 and the second linear module 421 are started to operate, so that the first mounting body 412 and the second mounting body 423 move upward at the same speed until the worm wheel 6 moves to the thickness dimension detection position of the worm wheel 6 in the clamping state. The first thickness detection sensor 523 and the second thickness detection sensor 524 detect the distance between the two detection positions and the two worm wheels 6, respectively, and since the relative distance between the two detection positions of the first thickness detection sensor 523 and the second thickness detection sensor 524 is known, the detection distance between the two detection positions is subtracted from the distance between the two detection positions, respectively, so as to obtain the thickness dimension of the worm wheel 6. If the worm wheel 6 has end face structures such as R-shaped grooves and bosses, the detection sampling position of the worm wheel 6 in the vertical direction can be changed by the synchronous operation of the first linear module 411 and the second linear module 421, and the height/depth of each structure in the thickness direction of the worm wheel 6 can be completed by the same method.
After the detection is completed, the first thickness detection sensor 523 and the second thickness detection sensor 524 are turned off, and the first linear module 411 and the second linear module 421 are started to operate, so that the components of the clamping and rotating device 4 are reset. At this time, the detected worm wheel 6 is located at the conveying height of the feeding and discharging device 3.
After all the size parameters are detected, the detected data are transmitted to data analysis processing software of a computer, fitting analysis of all size parameters of the worm wheel 6 is carried out, the result obtained by the fitting analysis is compared with the size of the corresponding theoretical parameter of the worm wheel 6, whether the size of the parameter of the worm wheel 6 is qualified or not is judged according to the analysis result, and the analysis result is automatically recorded.
(4) Discharging and blanking process
After the previous worm wheel 6 is detected, the step-by-step feeding mechanism 310 works to feed a worm wheel 6 to be detected, the detected worm wheel 6 is automatically pushed to the step-by-step discharging mechanism 320, and the step-by-step discharging mechanism 320 conveys the detected worm wheel 6 to a discharging position. If the detection result of the worm wheel 6 is unqualified, the system automatically starts the infrared detection sensor to work, and when the detected unqualified worm wheel 6 arrives, the step feeding and discharging mechanism 320 is controlled to pause working, the material rejecting mechanical arm 29 is started to work, and the unqualified worm wheel 6 is grabbed and placed in the material rejecting tray 210. After the picking manipulator 29 finishes picking, the infrared detector is automatically closed.
If the detection result of the worm wheel 6 is qualified, the step-in-and-out mechanism 320 directly conveys the detected worm wheel 6 to the discharging position, the infrared counting sensor records the number of the worm wheels 6 passing through in the conveying process, and when the count of the qualified worm wheel 6 is 7, the discharging manipulator 28 is automatically started to work, and 7 worm wheels 6 are simultaneously grabbed and placed in the discharging tray 25. The infrared counting sensor counts again, and the software system records the number of the qualified worm gears 6 and the unqualified worm gears 6.
Obviously, the worm wheel detecting and screening device provided by the invention is suitable for detecting the size parameters, fitting the shape curve and automatically comparing and analyzing the detection results of other types of gears, chain wheels, synchronizing wheels, spline shafts and other structures by slightly adjusting or replacing the clamping and rotating device 4.
