[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The bearing shaft measuring and processing device has an automatic conveying and automatic measurement classification structure. The automatic conveying can convey and move the measured bearing shaft, thereby ensuring the continuity of detection, and the automatic measurement classification can classify the measured bearing shaft to facilitate the later reprocessing of the bearing shaft, and the conveying and measurement classification can be operated continuously and effectively, thereby effectively improving the efficiency and speed of bearing shaft measurement, and also effectively ensuring the efficiency and speed of bearing shaft processing. At the same time, the bearing shaft measuring and processing device has a simple structural design, convenient and convenient measurement and use, and stable and reliable conveying and measurement classification. Its performance can meet the use requirements of bearing shaft processing; (2) By starting the double-output shaft motor to rotate the two discs, the rotation of the two discs will drive the arc-shaped transmission teeth and the arc-conical transmission rack thereon to rotate; first, the rotating arc-shaped transmission teeth will mesh with the tooth plate to toggle the tooth plate downward, and the downward movement of the tooth plate will drive the slider to slide downward on the first slide rod and pull and compress the first spring. At the same time, the downward movement of the tooth plate will drive the first gear to rotate, so that the two first gears drive the adjustment shaft to rotate, and the rotation of the adjustment shaft will drive the adjustment plate and the two toggle slots to rotate. The rotation of the two toggle slots will drive the two adjustment rods to move, so that one of the two adjustment rods moves upward and the other moves downward. The two adjustment rods moving up and down will drive the two baffles to move up and down through the fixed rod, and the two baffles adjusted up and down will transport the bearing shaft inside the conveying trough. At the same time, the baffles can effectively intercept and block other bearing shafts inside the conveying trough, so that the bearing shafts are transported one by one; The conveyed bearing shaft will automatically roll down between the two first clamping rollers. When the diameter of the bearing shaft is smaller than the distance between the two first clamping rollers, it means that the diameter of the bearing shaft is smaller than the minimum error value and is unqualified, so that the unqualified bearing shaft will automatically fall into the small diameter collection and discharge groove for centralized collection and processing; and when the bearing shaft is stuck between the two first clamping rollers, it means that the diameter of the bearing shaft is within the processing error value or greater than the maximum error value; When the arc-shaped transmission tooth is separated from the tooth plate, the elastic restoring force of the first spring will cause the slider to slide upward and reset, thereby driving the tooth plate to move upward, and at the same time, the tooth plate can be effectively moved upward and reset through the limit of the limit block; and the tooth plate that has moved upward and reset will reversely drive the first gear to rotate, and finally the two moving baffles, one up and one down, will be adjusted in the opposite direction and reset, so that the two baffles can effectively transport and block the bearing shaft; (3) When the arc-shaped transmission teeth are separated from the tooth plate, the arc-shaped conical transmission rack will transmit the small bevel gear to rotate, and the rotation of the small bevel gear will drive the transmission shaft and the large bevel gear to rotate, and the rotation of the large bevel gear will drive the middle bevel gear to rotate, and the rotation of the middle bevel gear will drive the first connecting shaft connected to it to rotate, and the rotation of the first connecting shaft will cause the four first chains on both sides of the device housing to rotate synchronously through the first sprocket, the first chain, the second sprocket and the second chain; and the rotation of the four first chains will drive the fixing pins thereon to rotate in a circle, and the rotation of the fixing pins in a circle will drive the hollow block to move in a circle through the bearing; (5) When the hollow block moves horizontally toward the slide plate at the lower end of the first chain, it will drive the T-block, the movable extrusion pin and the roller to move, and the movement of the movable extrusion pin will first push the slide plate on the first connecting shaft to move horizontally. The horizontal movement of the slide plate will drive the first connecting shaft to move horizontally and obliquely upward inside the first sliding groove and the middle sliding groove by toggling the vertical groove, and the horizontal and oblique upward movement of the first connecting shaft will drive the first clamping roller thereon to move toward another first connecting shaft and another first clamping roller; At this time, the bearing shaft stuck between the two first clamping rollers will be squeezed and moved, so that the bearing shaft is moved and transported to the two second clamping rollers. If the diameter of the bearing shaft is less than or equal to the distance between the two second clamping rollers, it means that the bearing shaft is qualified in processing diameter. At this time, the qualified bearing shaft will fall into the qualified diameter collection and discharge groove for centralized collection and processing; if the bearing shaft is stuck between the two second clamping rollers, it means that the diameter of the bearing shaft is greater than the maximum error value; The horizontal movement of the slide plate will slide horizontally on the second slide bar and compress the fourth spring, and then the moving roller will squeeze and move upward on the inclined surface of the right-angle triangle block, so that the moving squeeze pin will squeeze and move upward on one side of the slide plate, and the upward movement of the moving squeeze pin will drive the T-block to compress the third spring; When the roller moves to the top of the right-angle triangle block, the movable extrusion pin will separate from the slide plate. At this time, the elastic restoring force of the fourth spring will cause the slide plate to move back and drive the first connecting shaft and the first clamping roller to move back, and finally restore the distance between the two first clamping rollers to the original state. Similarly, as the hollow block continues to move and due to the elastic restoring force of the third spring, the T-shaped block, the moving extrusion pin, and the roller will move downward and reset. After that, horizontally moving the moving extrusion pin will push the slide plate on one of the second connecting shafts to move horizontally, so that the second connecting shaft drives the second roller on it to move horizontally and obliquely upward, thereby conveying and moving the bearing shaft with a diameter exceeding the error value stuck between the two second rollers. Finally, the bearing shaft with a diameter exceeding the error value will fall into the large-diameter collection and discharge groove for centralized collection and processing. After that, the second connecting shaft will also drive the second roller on it to reset, and the hollow block will move back and reset along with the first chain. Finally, the arc-shaped conical surface transmission rack will separate from the small bevel gear to complete one measurement and classification. Then, the arc-shaped transmission tooth will drive the toothed plate again to perform another conveying, measurement, and classification operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 4, on the basis of embodiment 3, the two first reciprocating components 22 and the two second reciprocating components 2201 each include a pair of second slide bars 57 fixedly mounted on both sides of the device housing 1, a slide plate 58 is slidably mounted between each pair of second slide bars 57, a fourth spring 59 is fixedly mounted between one side of the four slide plates 58 and the device housing 1, and a toggle vertical groove 60 is opened at the bottom of the four slide plates 58, the ends of one first connecting shaft 9 and one second connecting shaft 12 are respectively located inside the four toggle vertical grooves 60, and two right-angled triangular blocks 61 are fixedly mounted on both sides of the device housing 1, the right-angled triangular block 61 is located outside one side of the upper part of the slide plate 58, and a one-centimeter safety moving distance is set between the right-angled triangular block 61 and the side close to the slide plate 58, so that the right-angled triangular block 61 will not affect the horizontal movement of the slide plate 58.

[0030] A middle slide groove 62 is provided in the middle of the first sliding groove 10 and the second sliding groove 13. The first sliding groove 10, the second sliding groove 13 and the middle slide groove 62 are composed of a horizontal slide groove and an upward inclined slide groove. Moving wheels 63 are installed on the surfaces of the first connecting shaft 9 and the second connecting shaft 12 located inside the middle slide groove 62.

[0031] Specifically, when the hollow block 52 moves horizontally toward the slide plate 58 on the downward end of the first chain 48, it will drive the T-block 53, the movable extrusion pin 55 and the roller 56 to move, and the movement of the movable extrusion pin 55 will first push the slide plate 58 on the first connecting shaft 9 to move horizontally, and the horizontal movement of the slide plate 58 will drive the first connecting shaft 9 to move horizontally and obliquely upward inside the first sliding groove 10 and the middle slide groove 62 by toggling the vertical groove 60, and the horizontal and oblique upward movement of the first connecting shaft 9 will drive the first clamping roller 8 thereon to move toward another first connecting shaft 9 and another first clamping roller 8; At this time, the bearing shaft stuck between the two first clamping rollers 8 will be squeezed and moved, so that the bearing shaft is moved and transported to the two second clamping rollers 11. If the diameter of the bearing shaft is less than or equal to the distance between the two second clamping rollers 11, it means that the bearing shaft has a qualified processing diameter. At this time, the qualified bearing shaft will fall into the qualified diameter collection and discharge groove 15 for centralized collection and processing; if the bearing shaft is stuck between the two second clamping rollers 11, it means that the diameter of the bearing shaft is greater than the maximum error value; The horizontal movement of the slide plate 58 will slide horizontally on the second slide bar 57 and compress the fourth spring 59, and then the moving roller 56 will squeeze and move upward on the inclined surface of the right-angle triangle block 61, so that the moving squeeze pin 55 squeezes and moves upward on one side of the slide plate 58, and the upward movement of the moving squeeze pin 55 will drive the T-shaped block 53 to compress the third spring 54; After the roller 56 moves to the top of the right-angled triangular block 61, the moving extrusion pin 55 will separate from the sliding plate 58. At this time, due to the elastic restoring force of the fourth spring 59, the sliding plate 58 will move back, driving the first connecting shaft 9 and the first roller 8 to move back. Eventually, the distance between the two first rollers 8 will return to its original state. Similarly, as the hollow block 52 continues to move and due to the elastic restoring force of the third spring 54, the T-shaped block 53, the moving extrusion pin 55, and the roller 56 will move downward and reset. After that, horizontally moving the moving extrusion pin 55 will push the sliding plate 58 on one of the second connecting shafts 12 to move horizontally, so that the second connecting shaft 12 drives the second roller 11 thereon to move horizontally and obliquely upward, thereby conveying and moving the bearing shaft with a diameter exceeding the error value stuck between the two second rollers 11. Eventually, the bearing shaft with a diameter exceeding the error value will fall into the large-diameter collection and discharge groove 16 for centralized collection and processing. After that, the second connecting shaft 12 will also drive the second roller 11 thereon to reset, and the hollow block 52 will move back and reset along with the first chain 48. Eventually, the arc-shaped conical surface transmission rack 39 will separate from the small bevel gear 42 to complete one measurement and classification. Then, the arc-shaped transmission tooth 38 will drive the toothed plate 36 again to perform another conveying, measuring, and classification operation.
