DETAILED DESCRIPTION

[0026] If the inner ring of the bearing rotates while the stuck ball drives the outer ring to rotate, it needs to be recycled. However, the manual appearance inspection performed after the bearing is assembled cannot detect all parts of the product, and there is a possibility that defective products will be missed. When the existing inspection equipment detects a defect, it will prompt the staff by issuing an alarm, and the staff will then collect the defective bearings. However, the above operation is relatively cumbersome, the inspection effect is poor, and the labor cost is increased.

[0027] For example, see Figures 1 to 8 The present invention provides a technical solution: a rotation detection device for a mechanical part, comprising a workbench 1, a fixed frame 2 is arranged inside the workbench 1, a conveyor belt 3 is arranged inside the fixed frame 2, a plurality of detection bearings 6 are arranged on the surface of the conveyor belt 3, a transmission frame 7 is arranged inside the workbench 1 on the right side of the fixed frame 2, a rotating table 8 is rotatably connected to the upper end of the transmission frame 7, a conveying port 10 is fixedly opened on the front side of the rotating table 8, the transmission frame 7 is connected to the conveying port 10, and a driving card block 21 is arranged inside the workbench 1;

[0028] The middle part of the driving block 21 is rotatably connected with a transmission shaft 156, the upper end surface of the transmission shaft 156 is fixedly connected with an upper rotating wheel 157, the lower side of the middle part of the transmission shaft 156 is fixedly connected with a transmission gear 152, the lower end surface of the transmission shaft 156 is fixedly connected with a lower rotating wheel 155, the inside of the driving block 21 is slidably connected with a driving rack 151, the driving rack 151 is meshingly connected with the lower rotating wheel 155, the upper rotating wheel 157 is located inside the rotating table 8, the lower side of the driving block 21 is rotatably connected with a friction wheel 154, the upper end of the friction wheel 154 is fixedly connected with a driven gear 153, and the driven gear 153 is meshingly connected with the transmission gear 152.

[0029] When the driving block 21 drives the driving rack 151 to move downward, the driving rack 151 drives the driving portion 15 fixedly connected thereto to move downward, and the driving portion 15 moves rightward under the drive of the fixing rod 17;

[0030] When the driving block 21 drives the driving rack 151 to move upward, the driving part 15 moves leftward under the limit of the fixed rod 17, and the driving rack 151 drives the transmission gear 152 meshing with it to rotate while the driving gear 152 drives the transmission shaft 156 to rotate while driving the driven gear 153 to rotate, and the driven gear 153 drives the friction wheel 154 fixedly connected to it to rotate; when the transmission shaft 156 drives the upper rotating wheel 157 to descend to the lowest point, the bearing 6 moves rightward under the conveyance of the conveyor belt 3 and is sleeved on the upper side of the upper rotating wheel 157, and the upper rotating wheel 157 drives the bearing 6 to move upward while rotating the inner ring;

[0031] If the inner ring and the outer ring of the bearing 6 are stuck, the inner ring drives the outer ring to rotate together, and the outer ring forms a friction transmission with the inner part of the rotating platform 8. The rotating platform 8 rotates 90 degrees under the drive of the stuck bearing 6, and the upper rotating wheel 157 drives the bearing 6 to move upward. When the upper rotating wheel 157 drives the bearing 6 to move downward, the bearing 6 is gradually released from the connection with the upper rotating wheel 157, thereby realizing the detection of the inner ring of the bearing 6;

[0032] If the inner ring of the bearing 6 is of qualified quality, the upper rotating wheel 157 only drives the inner ring of the bearing 6 to rotate. When the transmission shaft 156 drives the lower rotating wheel 155 to move downward, the driving rack 151 drives the connecting plate 29 fixedly connected thereto to move rightward during the downward movement, and the connecting plate 29 drives the bearing plate 28 rotatably connected thereto to move rightward. The bearing plate 28 moves rightward to release the limit on the lower rotating wheel 155, and the lower rotating wheel 155 moves downward and contacts the bearing 6. The bearing 6 is sleeved on the surface of the lower rotating wheel 155 and moves upward. At this time, the upper rotating wheel 157 detects the inner ring of the next group of bearings 6, and then the transmission shaft 156 moves upward, the driving rack 151 drives the bearing plate 28 to move leftward, the lower rotating wheel 155 drives the inner ring of the bearing 6 to rotate, and the friction wheel 154 drives the outer ring of the bearing 6 to rotate in the opposite direction. The secondary detection is achieved by controlling the rotation of the inner and outer rings of the bearing 6 in different directions.

The limiting rod 14 is slidably connected to the inside of the limiting ring 13.

[0034] The right side of the driving part 15 is rotatably connected to a hinge plate 18 , and the lower side of the hinge plate 18 is rotatably connected to a connecting shaft 19 . The front and rear sides of the connecting shaft 19 are fixedly connected to an extrusion block 20 , and the extrusion block 20 is slidably connected to the inside of the driving block 21 .

[0035] When the lower rotating wheel 155 rises to the limit position and starts to descend, the driving part 15 drives the extrusion block 20 to move rightward through the hinge plate 18, and the bearing 6 sleeved on the surface of the lower rotating wheel 155 falls on the surface of the bearing plate 28 under the push of the arc surface of the extrusion block 20, and then the bearing plate 28 drives the bearing 6 to move to the upper side of the inner groove. When the bearing plate 28 drives the bearing 6 into the inner groove and moves downward, the bearing plate 28 controls the bearing 6 to move into the inner groove. At the same time, the upper rotating wheel 157 has completed the inner ring rotation detection of the next group of bearings 6;
