[0025] When in use, a workpiece is placed in the barrel 9 at the top of the barrel 9, and the first driving source 6 is controlled to drive the first incomplete gear 43 to rotate.

The workpiece can be supported when entering, and can be placed on the supporting plate 17 that has just entered at the bottom when moving out. This reciprocating operation is carried out for a certain period of time until the workpiece reaches the groove 18 below the barrel 9. Then the worker stops loading from the top of the barrel 9. The height of the barrel 9 and the number of supporting plates 17 can be designed according to the number of measurements each time, or they can be replenished after measuring a certain amount of workpieces without continuously occupying manpower. Then the first driving source 6 continues to operate. The groove 18 with the workpiece is displaced toward the push plate 38 during the period when the first incomplete gear 43 is meshed with the fourth gear 42. When the traction pin 21 corresponds to the push plate 38, the first incomplete gear 43 is separated from the fourth gear 42, and then meshed with the fifth gear 44. The dynamic feeding mechanism continues to feed, during which the multifunctional turntable 5 does not move. During feeding, the first traction frame 36 will drive the second traction frame 37 to move back and forth once, so that the second traction frame 37 drives the driving arm 41 and the driving pin 52 to move as a whole. Under the action of the fourth guide groove 51, the slide plate 8 moves outward, and one of the slide plates 8 drives the push plate 38 to move outward. The push plate 38 pushes the traction pin 21 to move in the first guide groove 26, and the third elastic member 33 is compressed, and then the driving plate 32 is driven to rotate. Under the action of the third guide groove 34 and the second guide groove 31, the centering pin 35 moves radially along the groove 18 to center the offset workpiece, and then the slide plate 8 is reset, the third elastic member 33 is reset, the centering pin 35 is reset and moved outward, and then the first incomplete gear 43 and The fifth gear 44 separates and meshes with the fourth gear 42, and the multifunctional turntable 5 continues to rotate. The centered workpiece moves toward the bottom of the high-speed camera 3. After arriving, the first incomplete gear 43 separates from the fourth gear 42 again and meshes with the fifth gear 44. During this period, loading, centering and measurement work are carried out. As the equipment runs, the measured workpiece gradually moves toward the slide plate 8 corresponding to the guide plate 39. After arriving, the first incomplete gear 43 will also separate from the fourth gear 42 and mesh with the fifth gear 44. Similar to the straightening principle, the guide plate 39 and the push rod 40 will be driven outward by the slide plate 8 on one side. Under the action of the guide plate 39, the roller 24 moves to the top of the guide plate 39, and the lifting frame 23 drives the lifting plate 20 to rise, and the second elastic member 29 is compressed.The lifting plate 20 lifts the measured workpiece to the top of the multifunctional turntable 5 and corresponds to the push plate 19. Then the push rod 40 contacts the side wall of the lower end of the traction plate 25. The push rod 40 pushes the traction plate 25 to move outward. The traction plate 25 drives the push plate 19 to move outward. The first elastic member 27 is compressed, and the push plate 19 pushes the workpiece on the top of the lifting plate 20 outward. After the measurement, the corresponding guide slide 4 is selected to correspond to the workpiece according to whether the workpiece is qualified. The two-layer guide slide 4 is controlled to rise and fall by the second driving source 7, one of which is used to discharge qualified workpieces, and the other is used to discharge unqualified workpieces. After the guide slide 4 corresponds to the workpiece, the push plate 19 can The workpiece is pushed into the corresponding guide slide 4, and then the first incomplete gear 43 continues to separate from the fifth gear 44 and meshes with the fourth gear 42, and the multifunctional turntable 5 continues to rotate, and the cycle is repeated. The workpiece to be measured can be stored in the barrel 9 during the whole process, without frequent manual participation. During loading, the high-speed camera 3 on the other side performs measurement, and the straightening component centers the workpiece after loading, and the unloading component unloads the workpiece after measurement. The equipment has high linkage, compact structure, low cost, and convenient maintenance. Only a set of gear racks and a specially designed multifunctional turntable 5 can realize continuous measurement operations, which increases practicality.
