[0019] The working principle of the present invention is as follows:
[0020] In order to improve the detection efficiency, the present invention adopts a dual-path simultaneous detection method. The working principle of each path is the same. The inner ring 9 of the bearing to be inspected is stringed on the material rod 36, and the inner ring 9 of the bearing to be inspected passes the material under the action of gravity. The blanking hole of the rod fixing lower seat 34 falls into the back buckle groove of the rod fixing lower seat 34, because the height of the back buckle groove of the rod fixing lower seat 34 is only slightly higher than the thickness of the bearing inner ring 9 to be inspected Therefore, only the bottom inner ring 9 of the bearing to be inspected is allowed to completely fall into the recessed groove of the lower seat 34 of the material rod and be completely separated from the material rod 36. When the piston rod of the imported material distribution cylinder 7 is extended, The distribution push plate 49 is fed into the reverse buckle groove of the lower seat 34 of the material rod fixing, thereby pushing the bottom bearing inner ring 9 to be inspected onto the conveyor belt 10. When the piston rod of the imported material distribution cylinder 7 contracts, The distributing push plate 49 retracts and exits the back-locking groove of the lower seat 34 of the material rod fixing, and a new bearing inner ring 9 to be inspected falls into the back-locking groove of the lower seat 34 of the material rod fixing. Controlling the movement frequency of the piston rod of the imported material distribution cylinder 7 can control the material distribution speed. The conveyor motor 1 drives the rotation of the meshing gear set 2, thereby driving the movement of the left and right conveyor belts 10. By adjusting the rotation speed of the conveyor motor 1, you can Adjust the moving speed of the conveyor belt 10. When the conveyor belt 10 conveys the inner ring 9 of the bearing to be inspected, it passes under the feed detection switch 6 and the shortage detection switch 5 one after another. Normally, there is always a bearing to be inspected under the shortage detection switch 5 If the inner ring 9 is present, otherwise the shortage alarm will be activated. When the inner ring 9 of the bearing to be inspected under the feed detection switch 6 exists, the imported material distribution mechanism 7 will not operate, and there is no inner ring of the bearing to be inspected under the feed detection switch 6 When 9 exists, the imported material distribution mechanism 7 will act, and the conveyor belt 10 will send the inner ring 9 of the bearing to be inspected to the front of the feeding rod 4, which is blocked by the protrusion of the station 48. When the piston rod of the feeding cylinder 3 is extended , The feeding rod 4 pushes a bearing inner ring 9 to be inspected to the first station of the station 48. At this time, the station pushes the cylinder 11 to contract, and then the station clamps the cylinder 13 to extend, and the first station The inner ring 9 of the bearing to be inspected on the upper part is clamped between the protrusion of the station 48 and the gap of the clamping plate 14 of the station, and then the station pushes the cylinder 11 to extend, and the inner ring of the bearing to be inspected on the first station 9 is sent to the second station of the station table 48. At this time, the lifting motor 42 drives the screw 44 to rotate, so that the nut 40, the lifting table 39, the X-direction inner diameter detection sensor 37 and the Y-direction inner diameter detection sensor 47 move downward , Move to a certain position and stop, the Y-direction inner diameter detection sensor 47 extends into the hole of the bearing inner ring 9 to be inspected, measures the Y-direction inner diameter on the first section of the bearing inner ring 9 to be inspected, and then the lifting motor 42 drives the lead screw 44 continues to rotate, the Y-direction inner diameter detection sensor 47 continues to descend until the measuring zero switch 46 senses the lifting platform 39 to measure the Y-direction inner diameter on the second section of the bearing inner ring 9 to be inspected, and then the lifting motor 42 drives the wire The bar 44 is reversed, and the Y-direction inner diameter detection sensor 47 moves upward with the lifting platform 39 until the calibration zero switch 45 senses the lifting platform 39. At this time , The station chucking cylinder 13 shrinks, then the station pushing cylinder 11 shrinks, and then the station chucking cylinder 13 extends, repeating the previous action, and the inner ring of the bearing to be inspected on the first station of the station 48 9 Push to the second station, push the inner ring 9 of the bearing to be inspected on the second station of the station 48 to the third station, and push the third station to the fourth In the station, the fourth station is pushed to the fifth station. When the bearing inner ring 9 to be inspected is on the third station of the station 48, it is similar to the second station. 39 is lowered twice, the X-direction inner diameter detection sensor 37 measures the X-direction inner diameters on the two different sections of the bearing inner ring 9 to be inspected. In this way, through the numerical calculation of the inner diameters of the different sections, the inner hole taper of the bearing inner ring 9 to be inspected can be calculated , Through the numerical calculation of X-direction inner diameter and Y-direction inner diameter, the inner hole roundness of the bearing inner ring 9 to be inspected can be calculated, and the measured and calculated inner diameter value, taper value and roundness value are respectively carried out with the set value Based on this, it is determined whether the bearing inner ring 9 to be inspected is a qualified part, a scrapped part or a reworked part. If it is a scrapped part, when the bearing inner ring 9 to be inspected is pushed to the fourth station of the station 48, the scrap area When the baffle 15 is on top, the cylinder 33 in the scrap area is contracted, and the baffle 15 in the scrap area is pulled open, so that the bearing inner ring 9 to be inspected falls into the gap in the scrap area of the station table 48, and then falls out of the scrap exit 16. If the bearing inner ring 9 to be inspected is not a scrapped part, but a reworked part, when the bearing inner ring 9 to be inspected is pushed to the fourth station of the station table 48, the cylinder 33 in the scrapped area does not act, that is, it keeps extending In the long state, the inner ring 9 of the bearing to be inspected will continue to be sent to the fifth station, which is above the baffle 18 in the rework area. The execution cylinder 32 of the rework area is contracted, and the baffle 18 of the rework area is pulled apart to make the bearing The ring 9 falls into the gap in the repair area of the station 48, and then falls out of the repair exit 19. If the inner ring 9 of the bearing to be inspected is a qualified part, the cylinder 32 in the repair area will not operate in the fifth station. That is, the extended state is maintained. When the cylinder 11 is extended at the station, the pushing block 17 pushes the inner ring 9 of the bearing to be inspected into the outlet hopper 31. At this time, the inner ring of the bearing to be inspected 9 is converted into a qualified bearing inner ring 25. When the outlet dividing cylinder 21 is extended, the gap of the outlet dividing block 30 is aligned with the bottom of the outlet dividing hopper 31, a qualified bearing inner ring 25 falls into the gap of the outlet dividing block 30, and then the outlet dividing cylinder 21 shrinks , And then the outlet pushing cylinder 20 extends, pushing the qualified bearing inner ring 25 that fell into the gap of the outlet dividing block 30 into the small groove 26, and so on, the qualified bearing inner ring 25 in the outlet dividing hopper 31 It is gradually pushed into the small groove 26 for arrangement. When the qualified bearing inner ring 25 in the small groove 26 is arranged below the discharge detection switch 27, the discharge cylinder 29 is extended, and the discharge plate 28 pushes the small groove 26 The middle row of qualified bearing inner rings 25 into the discharge frame 23. The stopper 24 in the discharge frame 23 is used to maintain the orderliness of the entire row of qualified bearing inner rings 25. When the stopper 24 is pushed to the full material When the bottom of the switch 22 is detected, the full material alarm of the system will be triggered to indicate The user immediately processes the material in the discharge frame 23.
