[0019] In the existing optical photography inspection of nuts, most of them only take multiple single-angle photography inspections of the nuts. In this way, the photography with a constant angle cannot perform the same degree of inspection on all vertical areas of the thread on the nut, resulting in the problem of incomplete nut inspection, which makes the inspection results not referenceable and affects the staff's correct judgment on whether the nuts are qualified.

[0021] like Figure 4 and Figure 6 As shown, the clamping mechanism includes a rotating plate 1301, which is rotatably connected to the upper side of the horizontal plate 3, and a second rotating member 1302 is fixedly connected to the rear portion of the upper side of the rotating plate 1301, and two first limiting grooves 1303 arranged in a left and right mirror image are provided on the front side of the second rotating member 1302, and a second limiting member 1304 is slidably provided in the first limiting groove 1303, and opposite sides of the two second limiting members 1304 are slidably connected with a clamping member 1305, and a first elastic element 1306 is fixedly connected between the clamping member 1305 and the adjacent second limiting member 1304, and the first elastic element 1306 is a spring for applying elastic force to the adjacent clamping member 1305, and a transmission component for making the clamping member 1305 and the second rotating member 1302 rotate relative to each other is provided on the upper side of the horizontal plate 3.

[0022] like Figure 3-Figure 6As shown, the transmission assembly includes a first fixed member 1401, the first fixed member 1401 is fixedly connected to the rear side of the cross plate 3, a hydraulic push rod 1402 is installed on the upper part of the first fixed member 1401, the telescopic end of the hydraulic push rod 1402 is fixedly connected to a moving member 1403, a second limiting groove 1404 is arranged on the outer side of the moving member 1403, a limiting ring 1405 is fixedly connected to the middle part of the front side of the first fixed member 1401, an intermediate block 1406 is slidingly connected to the inner side of the limiting ring 1405, the intermediate block 1406 is slidingly connected to a rotating frame 1407 slidingly connected to the second rotating member 1302, the second limiting groove 1404 is a closed groove composed of a straight groove and a spiral groove connected, which is used to make the rotating frame 1407 and the limiting ring 1405 move relative to each other, the straight groove is a vertical groove, the groove depth of the spiral groove gradually increases from top to bottom, and there is a step at the connection between the straight groove and the lower side of the spiral groove, the intermediate block 1406 and the limiting ring 1405 There is friction between them, which is used to make the rotating frame 1407 and the middle block 1406 slide relative to each other, and then make the rotating frame 1407 drive the middle block 1406 to rotate along the limiting ring 1405. Two third limiting grooves 1408 arranged in left and right mirror images are provided on the lower side of the rotating frame 1407, and the distance between the two third limiting grooves 1408 gradually decreases from bottom to top. The third limiting groove 1408 is limited and matched with the adjacent second limiting member 1304, and the adjacent second limiting member 1304 is squeezed through the third limiting groove 1408 to make the two second limiting members 1304 move relative to each other. A spring block 1409 that is limited and matched with the second limiting groove 1404 is installed on the front part of the upper side of the rotating frame 1407. The spring block 1409 is limited and squeezed through the second limiting groove 1404, so that the spring block 1409 drives the rotating frame 1407 to move together, so as to perform all-round detection of the nut 101 later.

[0023] like Figure 4 and Figure 6 As shown, the lower side of the movable member 1403 is slidably connected to the second fixed member 1410, and a second elastic element 1411 is fixed between the second fixed member 1410 and the movable member 1403. The second elastic element 1411 is a spring for applying elastic force to the second fixed member 1410. The lower side of the second fixed member 1410 is fixed to a support member 1412, and the support member 1412 is rotatably connected to a pressure ring 1413. The pressure ring 1413 is fixed to four evenly arranged inclined plates, and the distance between the four inclined plates gradually increases from top to bottom, which is used to extrude and center the nut 101.

[0024] When it is necessary to use the device to detect the nut 101, the staff places the nut 101 in the middle of the upper side of the horizontal plate 3 and starts the motor 2, the optical detection module 9 and the hydraulic push rod 1402. The telescopic end of the hydraulic push rod 1402 drives the moving part 1403 to start moving downward, and the spiral groove on the second limiting groove 1404 starts to squeeze the spring block 1409. At this time, the squeezing force of the spiral groove on the spring block 1409 is vertically downward and perpendicular to the adjacent area of ​​the spiral groove and obliquely downward, and the oblique downward force on the spring block 1409 is offset by the friction between the middle block 1406 and the limiting ring 1405. Therefore, the moving part 1403 moves downward first, driving the spring block 1409 and the rotating frame 1407 to move downward together, and the rotating frame 1407 and the middle block 1406 move downward together. Relative sliding occurs, and the third limiting groove 1408 squeezes the adjacent second limiting member 1304. Subsequently, the two second limiting members 1304 begin to move toward each other, and the second limiting members 1304 drive the adjacent clamping members 1305 and the adjacent first elastic element 1306 to move together. When the two clamping members 1305 move toward each other until they are in contact with the nut 101, as the two second limiting members 1304 continue to move toward each other, the second limiting members 1304 and the adjacent clamping members 1305 slide relative to each other, and the adjacent first elastic element 1306 is compressed. The nut 101 is fixedly clamped by the elastic force generated when the first elastic element 1306 is compressed, thereby ensuring the stable position of the nut 101 in the subsequent detection process, thereby improving the detection effect of the nut 101.

[0025] During the downward movement of the moving member 1403, when the first elastic element 1306 is compressed to the limit state, the moving member 1403 continues to move downward, but the spring block 1409 cannot move downward any further. Then, the spring block 1409 starts to rotate clockwise (in degrees) under the action of the spiral groove on the second limiting groove 1404. Figure 4 Taking the top view as an example), the spring block 1409 slides in the spiral groove on the second limit groove 1404, and the spring block 1409 is gradually compressed. The spring block 1409 drives the rotating frame 1407 to rotate clockwise, and the rotating frame 1407 drives the second rotating member 1302 and the parts thereon to rotate clockwise, that is, the nut 101 starts to rotate clockwise, thereby changing the area in which the nut 101 faces the optical detection module 9 during the detection process, so that the optical detection module 9 can fully detect the nut 101 during the rotation process, thereby improving the reference of the detection result of the nut 101.

[0026] When the pressing ring 1413 moves downward until the inclined plate on it contacts the nut 101, as the moving member 1403 continues to move downward, the inclined plate on the pressing ring 1413 begins to transfer the nut 101 to the detection area, so as to ensure the accurate position of the nut 101 during the detection process, thereby improving the accuracy of the subsequent detection results of the nut 101. After the four inclined plates are in contact with the nut 101, the moving member 1403 and the second fixing member 1410 slide relative to each other, and the second elastic element 1411 is compressed. During the clockwise rotation of the nut 101, the nut 101 drives the pressing ring 1413 to rotate clockwise together through friction, and the pressing ring 1413 and the support member 1412 rotate relative to each other.

[0027] When motor 2 is started, the output shaft of motor 2 starts to rotate counterclockwise (in Figure 2 Taking the front view direction as an example), the output shaft of the motor 2 transmits power to the third shaft 12 through the bevel gear set and the pulley belt, and then the third shaft 12 starts to rotate clockwise (with Figure 2 Taking the top view as an example), the third shaft 12 transmits power to the first shaft 5 through the pulley belt, and the first shaft 5 starts to rotate clockwise. The first shaft 5 transmits power to the second shaft 7 through the bevel gear set, and the second shaft 7 rotates counterclockwise (with Figure 2 Taking the left viewing direction as an example), the second shaft 7 drives the first rotating member 11 to rotate counterclockwise, the first rotating member 11 drives the first limiting member 10 to rotate counterclockwise, the first limiting member 10 drives the deflection frame 8 to start to deflect downward, the deflection frame 8 drives the optical detection module 9 to deflect upward, and then the working optical detection module 9 starts to perform a comprehensive inspection on the nut 101 to avoid the traditional inspection method being unable to perform the same degree of inspection on all parts of the thread on the nut 101, which results in the inspection result of the nut 101 being not of reference value, affecting the staff's judgment on the quality of the tested nut 101.

[0028] When the spring block 1409 rotates clockwise to enter the straight groove on the second limiting groove 1404, the detection of the single nut 101 is completed, and then the staff moves the telescopic end of the hydraulic push rod 1402 upward, and the telescopic end of the hydraulic push rod 1402 drives the moving part 1403 and the parts thereon to move upward together, and the spring block 1409 begins to slide along the straight groove on the second limiting groove 1404, and resets after the spring block 1409 enters the spiral groove on the second limiting groove 1404 again. As the moving part 1403 continues to move upward, the moving part 1403 drives the spring block 1409 and the parts thereon to move upward together. During the process, the two clamping parts 1305 gradually release the nut 101, and then the staff removes the nut 101 that has been detected, and repeats this operation until the detection of all nuts 101 is completed, and the staff can turn off the motor 2, the optical detection module 9 and the hydraulic push rod 1402.

[0029] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 7-10As shown, it also includes a rotating shell 1501 rotatably connected to the frame body 1, the rotating shell 1501 is fixedly connected to the upper side of the third axis 12, the movable plate 4 is slidably connected to the horizontal plate 3, the lower side of the horizontal plate 3 is limited and slidably connected to the limiting rod 1502, the rotating shell 1501 is provided with a fourth limiting groove 1503 limited by the limiting rod 1502, the upper side of the limiting rod 1502 is slidably matched with the moving rod 1504, the left part of the upper side of the frame body 1 is slidably connected to the first movable frame 1505 slidably connected to the horizontal plate 3, the first movable frame 1505 is fixedly connected to the movable plate 4, the horizontal plate 3 The rear side is fixedly connected to a limit plate 1506, which is provided with a connected vertical slot and a through slot, both of which are limited by the moving rod 1504, the upper side of the through slot on the limit plate 1506 is parallel to the horizontal plane, and the lower side of the through slot gradually tilts downward from left to right, which is used to reset the moving rod 1504, and the lower side of the horizontal plate 3 is slidably connected to a second moving frame 1507 slidably connected to the moving rod 1504, and the lower side of the horizontal plate 3 is rotatably connected to a rotating shaft 1508 through a vertical rod, and the rotating shaft 1508 is fixedly connected to two intermediate gears 1509 arranged in front and back mirror images The second moving frame 1507 is fixedly connected with two first racks 1510 arranged in a front-to-back mirror image. A third elastic element 1511 is fixedly connected between the second moving frame 1507 and the cross plate 3. The third elastic element 1511 is a tension spring, and the third elastic element 1511 is initially in a stretched state, and is used to apply tension to the second moving frame 1507. The right part of the lower side of the first moving frame 1505 is fixedly connected with two second racks 1512 arranged in a front-to-back mirror image. The second racks 1512 and the first racks 1510 are respectively meshed with the adjacent intermediate gears 1509. The moving rod 1504 The outer side of the nut 101 is modulated to reduce the friction between the two when the two slide relative to each other, and the horizontal axis of the first limit member 10 is parallel to the axis of the second shaft 7, so that when the movable plate 4 slides relative to the cross plate 3, the deflection frame 8 remains stationary relative to the movable plate 4. The fourth limit groove 1503 is composed of two evenly arranged horizontal arc grooves and two evenly arranged inclined arc grooves connected to each other. The two horizontal arc grooves and the two inclined arc grooves are staggered, so as to enable the limit rod 1502 to move up and down relative to the rotating shell 1501.

[0030] During the clockwise rotation of the third shaft 12, the third shaft 12 drives the rotating shell 1501 to rotate clockwise together, and the limiting rod 1502 begins to slide in the horizontal arc groove on the lower side of the fourth limiting groove 1503. When the rotating shell 1501 rotates clockwise until the limiting rod 1502 enters the inclined arc groove on the rear side of the fourth limiting groove 1503, as the rotating shell 1501 continues to rotate clockwise, the inclined arc groove on the rear side begins to squeeze the limiting rod 1502 upward, and then the limiting rod 1502 begins to move upward, and the limiting rod 1502 drives the moving rod 1504 to move upward together, and the moving rod 1504 begins to slide upward along the vertical groove on the limiting plate 1506, and the moving rod 1504 and the second moving frame 1501 are connected. 07 relative sliding occurs. When the moving rod 1504 moves upward to enter the inclined groove on the limiting plate 1506, the second moving frame 1507 begins to move to the left under the pulling force of the third elastic element 1511, and the second moving frame 1507 drives the moving rod 1504 to move to the left together. During the process, the moving rod 1504 is close to the lower side of the inclined groove on the limiting plate 1506 until the moving rod 1504 moves to the left to contact the nut 101, and the moving rod 1504 stops moving to the left, thereby completing the detection of the inner diameter of the nut 101. When the rotating shell 1501 rotates clockwise until the limiting rod 1502 enters the horizontal arc groove on the upper side of the fourth limiting groove 1503, the moving rod 1504 stops moving upward.

[0031] During the process of the second movable frame 1507 moving to the left, the second movable frame 1507 drives the two first racks 1510 to move to the left together, the first rack 1510 drives the adjacent second rack 1512 to move to the right through the adjacent intermediate gear 1509, the two second racks 1512 jointly drive the first movable frame 1505 to move to the right together, and the first movable frame 1505 drives the movable plate 4 and the parts thereon to move to the right together, thereby changing the position of the optical detection module 9, so that the optical detection module 9 automatically adjusts to the position required for detecting nuts 101 with different inner diameters, so that when detecting nuts 101 with different inner diameters, the distance between the optical detection module 9 and the threaded protrusions in the detection area of ​​the nut 10 is equal, thereby improving the clarity of the detection of the nut 101, and improving the scope of application of the device, and reducing the operating steps of the staff, thereby improving work efficiency.

[0032] When the rotating shell 1501 rotates clockwise until the limiting rod 1502 enters the inclined arc groove on the front side of the fourth limiting groove 1503, as the rotating shell 1501 continues to rotate clockwise, the inclined arc groove on the front side begins to squeeze the limiting rod 1502 downward, and the limiting rod 1502 drives the moving rod 1504 to start moving downward. After the moving rod 1504 moves downward until it contacts the lower inclined surface of the through groove on the limiting plate 1506, the moving rod 1504 starts to move to the right under the squeezing action of the lower inclined surface of the through groove, and the moving rod 1504 drives the second moving frame 1507 to move to the right together, the third elastic element 1511 is stretched, and the second moving frame 1507 passes through the middle The gear 1509 drives the adjacent second rack 1512 to move to the left, and the two second racks 1512 jointly drive the first moving frame 1505 to move to the left together. The first moving frame 1505 drives the moving plate 4 and the parts thereon to move to the left and reset. After the moving rod 1504 moves to the right and enters the vertical groove on the limit plate 1506, the moving rod 1504 starts to move vertically downward until the limit rod 1502 rotates clockwise and enters the horizontal arc groove on the lower side of the fourth limit groove 1503 and then stops moving. In this way, all parts are restored to their initial state. As the detection work continues, the above actions are repeated until the detection of all nuts 101 is completed.
