[0047] Working principle of the present invention:

[0048] First, the motor 9 is controlled to work so that the motor 9 drives the half gear 10 fixedly connected to its output shaft to rotate. At this time, the half gear 10 will mesh with the full gear 1 615, so that the full gear 1 615 drives the vertical rod 614 fixedly connected to it to rotate. When the vertical rod 614 rotates, it drives the driving wheel 1 613 fixedly connected to it to rotate, so that the driving wheel 1 613 drives the driven wheel 1 611 to rotate through the belt 1 612. When the driven wheel 1 611 rotates, it drives the vertical rod 610 fixedly connected to it to rotate, so that The vertical rod 610 drives the eccentric wheel 68 fixedly connected thereto to rotate, and the eccentric wheel 68 drives the connecting frame 66 to move close to the detection box 1 when rotating, so that the connecting frame 66 drives the connecting plate 65 fixedly connected thereto to move, and the connecting plate 65 drives the push plate 64 fixedly connected thereto to move when moving, so that the bar material at the bottom of the storage box 61 is transported to the placement box 4 through the unloading box 63, and then the eccentric wheel 68 controls the connecting frame 66 to move in the reverse direction and return to the initial position, at which time, the half gear 10 is disengaged from the full gear 1 615;

[0049] When the half gear 10 is disengaged from the full gear 1 615, the half gear 10 will mesh with the full gear 2 12, so that the full gear 2 12 drives the connecting rod 11 fixedly connected thereto to rotate, and when the connecting rod 11 rotates, it drives the cross plate 3 fixedly connected thereto to rotate, so that the cross plate 3 drives the placement box 4 fixedly connected thereto to rotate, so as to rotate the placement box 4 in the unloading area to the cleaning area, and when the placement box 4 rotates to the cleaning area, the gear teeth 59 will drive the driving gear 1 57 to rotate, so that the driving gear 1 57 drives the rotating shaft 56 fixedly connected thereto to rotate, and when the rotating shaft 56 rotates, it drives the driving bevel wheel 1 55 fixedly connected thereto to rotate, so that the driving bevel wheel 1 55 drives the driven bevel wheel 1 54 meshed therewith to rotate, and when the driven bevel wheel 1 54 rotates, it drives the rotating rod 52 fixedly connected thereto to rotate, so that the rotating rod 52 drives the friction wheel 53 fixedly connected thereto to rotate, and when the friction wheel 53 rotates, it drives the bar material above it to rotate;

[0050] When the placement box 4 rotates to the cleaning area, the half gear 10 will disengage from the full gear 2 12 and mesh with the full gear 1 615 again, and the gear tooth 59 will disengage from the driving gear 1 57. At this time, the driven gear 1 510 will drive the driving gear 1 57 to reverse under the action of the spring 512, thereby controlling the rotation of the bar material again. At the same time, the vertical rod 610 will drive the active bevel wheel 2 79 fixedly connected thereto to rotate, so that the active bevel wheel 2 79 drives the driven bevel wheel 2 78 meshed therewith to rotate, and the driven bevel wheel 2 78 will drive the linkage rod 77 fixedly connected thereto to rotate when rotating, so that the linkage rod 77 drives the active wheel 2 710 fixedly connected thereto to rotate, and the active wheel 2 710 will drive the driven wheel 2 712 to rotate through the belt 2 711 when rotating. When the driven wheel 712 is driven by the driven wheel 713, the driven wheel 713 can rotate, and the driven wheel 713 can drive the active cone wheel 714 to rotate, so that the active cone wheel 714 drives the driven cone wheel 715 meshing with it to rotate, and the driven cone wheel 715 can drive the connecting shaft 716 to rotate, so that the connecting shaft 716 drives the threaded rod 72 to rotate, and the threaded rod 72 can drive the movable seat 73 to move, so that the movable seat 73 drives the mounting plate 717 to move, and the mounting plate 717 can drive the brush 718 to move, so that the brush 718 can wipe and clean the surface of the bar.

[0051] When the bar material is cleaned, the half gear 10 will be disengaged from the full gear 1 615 and meshed with the full gear 2 12 again, so as to transport the placement box 4 in the cleaning area to the detection area. At this time, the gear 59 will drive the active gear 1 57 to rotate, so as to control the rotation of the bar material. After being transported to the detection area, the gear 59 will be disengaged from the active gear 1 57. At this time, the bar material will rotate again. When the bar material rotates, the bar material will squeeze the arc block 86 upward due to the radial circular runout, so that the arc block 86 moves upward. When the arc block 86 moves, it will drive the movable rod 85 fixedly connected thereto to move, so that the movable rod 85 drives the limit plate 83 fixedly connected thereto to move, and the limit plate 83 moves. The worm 87 fixedly connected thereto will be driven to move upward, so that the worm 87 drives the worm wheel 88 meshing therewith to rotate, and when the worm wheel 88 rotates, it will drive the cross bar 89 fixedly connected thereto to rotate, so that the cross bar 89 drives the active bevel wheel 4 811 fixedly connected thereto to rotate, and when the active bevel wheel 4 811 rotates, it will drive the driven bevel wheel 4 812 meshing therewith to rotate, so that the driven bevel wheel 4 812 drives the transmission shaft 816 fixedly connected thereto to rotate, and when the transmission shaft 816 rotates, it will drive the pointer 814 fixedly connected thereto, so that according to the direction of the pointer 814 on the dial 813 and whether it contacts the early warning block 815, it is judged whether the roundness and axial runout of the bar material are qualified;

[0052] After the detection is completed, the half gear 10 will mesh with the full gear 2 12 again, so that the bars in the detection area are transported to the receiving area so that the staff can collect the detected bars.
