Specifically, the groove width of arc wall 103 is less than gyro wheel 5111 thickness, the above-mentioned chain after measuring can be put into in the feed box 101, lead to the yields to mix together with the defective products, carry out the defective products to the chain subsequently, therefore under the initial condition, second cylinder 102 is in the extension state, the second cylinder 102 of extension can push arc 104 upwards slide along arc wall 103, make arc 104 most break away from arc wall 103, when the measured chain is the yields, the chain of yields is along with chain rack 5 rotation, the gyro wheel 5111 of L shaped pole 511 lower extreme can roll along base 1 up end, until gyro wheel 5111 contacts the inclined plane 1041 of arc 104 other end, gyro wheel 5111 can roll along inclined plane 1041, simultaneously inclined plane 1041 pushes away gyro wheel 5111, make L shaped rod 511 upwards move, thereby realize in the feed box 101 of above-mentioned chain whereabouts below, when the measured chain is the defective products, second cylinder 102 pulls arc wall 103 into arc wall 104, can be along with the chain drive the chain is the defective products, thereby the same position is directly carried out to the second cylinder 104, the defective products is triggered to the second cylinder 102, thereby the defective products is located in the arc 101, the same position is triggered to the defective products, the same place is carried out in the arc 102, the defective products is automatically pushed down along with the chain is in the inclined plane 1041, the position is triggered to the defective products, the top is located in the top of the cylinder is in the stage, the defective products, the top is detected.
Working principle: the initial value displayed on the reading head 81 is corrected to be the center distance between the first limiting piece 505 and the second fixed limiting piece 506, then a group of chains to be tested is hung on the first limiting piece 505 of the group of chain placing frames 5, the chains to be tested are naturally straightened under the action of gravity, the inner rings of the chains are tightly attached to the outer rings of the pull columns 51, the cover plate 52 plays a limiting role on the chains, the chains are placed on the chain placing frames 5 more firmly, then the driving shaft 4 is rotated 120 degrees through a motor, the rotating direction is the arrow indication direction in the figure 1, meanwhile, the driving shaft 4 drives the conversion frame 3 to rotate together with the three groups of chain placing frames 5, the chain placing frames 5 with the chains placed thereon are rotated to one side of the mounting plate 6, at the moment, the bearing plate 504 on the chain placing frames 5 is positioned right above the first air cylinders 7, and the lower end surface of the bearing plate 504 is attached to the upper end surface of the first cylinder 7, then the first cylinder 7 is started, the first cylinder 7 pushes the bearing plate 504 upwards, and the first cylinder 7 pulls the reading head 81 to slide along the ruler body of the grating ruler 8, meanwhile, the bearing plate 504 drives the sliding block 503 to move upwards together with the first limiting piece 505, the first limiting piece 505 drives the chain to move upwards until the lower end of the chain is pulled by the second limiting piece 506 and cannot move, at the moment, the first cylinder 7 cannot continue pushing, the reading head 81 displays the center distance of the chain, the measurement of the center distance of the chain is realized, the next group of chains to be measured can be placed on the next group of chain placing frames 5 in the chain measurement process, after the grating ruler 8 finishes measuring the chains, the first cylinder 7 is withdrawn, the sliding block 503 falls back to the original position under the action of gravity, and then the conversion frame 3 is continuously driven to rotate, repeating the operation circularly;
After the measurement of the chain on the chain placing frame 5 is finished, the conversion frame 3 is driven to rotate continuously, the measured chain rotates 120 degrees along with the chain placing frame 5, so that the lower end of the L-shaped rod 511 on the chain placing frame 5 is positioned right above the second air cylinder 102, at the moment, the second air cylinder 102 can be started at the same time in the process of measuring the chain by the grating scale 8, the second air cylinder 102 pushes the L-shaped rod 511 upwards, the L-shaped rod 511 drives the inner movable plate 507 to slide upwards along the inner cavity of the main frame body 501, the inner movable plate 507 stretches the spring 512, simultaneously, the two groups of first shifting rods 713 slide along the corresponding first inclined grooves 711 at first, the two groups of first shifting rods 713 move back along the guide posts 5013 under the guidance of the first inclined grooves 711, the inner circle of the chain is propped by the two groups of first shifting rods 713, the limit of the cover plate 52 on the second fixed limiting piece 506 is relieved, until the first deflector rod 713 slides into the first linear groove 712, in the process, the inner movable plate 507 pushes the two groups of guide blocks 509 to move upwards together with the two groups of second deflector rods 510, the bent angle ends 5101 on the second deflector rods 510 slide along the second inclined grooves 111 first, under the guidance of the second inclined grooves 111, the two groups of second deflector rods 510 drive the two groups of guide blocks 509 to move back along the sliding grooves 508, then the inner rings of the chains are propped up by the two groups of bent angle ends 5101 which move back, the bent angle ends 5101 synchronously move upwards, the bent angle ends 5101 push the chains to move upwards, so that the limit of the cover plate 52 on the first limiting piece 505 on the chains is released, the inner rings of the chains are separated from contact with the outer rings of the pull columns 51, and under the action of gravity, the inner rings at the upper ends of the chains slide downwards along the bent angle ends 5101, so that the chains fall into the lower discharging boxes 101;
when the measured chain is good, when the good chain rotates along with the chain placing frame 5, the roller 5111 at the lower end of the L-shaped rod 511 rolls along the upper end face of the base 1 until the roller 5111 contacts the inclined face 1041 at the other end of the arc plate 104, the roller 5111 rolls along the inclined face 1041, and meanwhile, the inclined face 1041 pushes the roller 5111 to enable the L-shaped rod 511 to move upwards, so that the chain falls into the lower discharging box 101, when the measured chain is bad, the arc plate 104 is pulled into the arc groove 103 by the second cylinder 102, the bad chain can directly rotate to the second cylinder 102 along with the chain placing frame 5, at the moment, the second cylinder 102 pushes the arc plate 104, the arc plate 104 pushes the roller 5111, the bad chain falls into the discharging box 101, and the position of the triggering roller 5111 is different because the inclined face 1041 and the second cylinder 102 are not in the same position, and the position of the bad chain falling into the discharging box 101 is different.
