[0024] Example:
[0025] See also Figure 1-Figure 6As shown, a magnetic core quality inspection device includes a side plate 1 and a limit strip 20, two side plates 1 are arranged in parallel, a connecting plate 101 is evenly arranged between the two side plates 1, a conveyor belt 2 is installed between the two side plates 1, the connecting plates 101 and the rollers of the conveyor belt 2 are staggered and the upper and lower surfaces are not in contact with the conveyor belt 2, the inner side of the conveyor belt 2 between the connecting plates 101, a visual detector 3 is spanned on the top of the two side plates 1, and an alarm 4 is arranged on the top of the visual detector 3 to take pictures of the magnetic cores on the surface of the conveyor belt 2 to achieve visual inspection, so as to detect the appearance of the magnetic core, limit grooves 102 are evenly arranged on the outer surface of the side plate 1, and protrusions 5 are evenly arranged on the side close to each other on the upper surface of the side plate 1, and the protrusions 5 correspond to the limit grooves 102 one by one, and a vertical plate 7 is slidably installed on the inner side of the limit groove 102, and a vertical plate 7 is arranged above the side close to each other of the two vertical plates 7 in the same group. There is a slide bar 8, which is placed above the side plate 1. The slide bar 8 passes through the protrusion 5. The limit bar 20 is symmetrically suspended above the conveyor belt 2. The ends of the multiple slide bars 8 on the same side that are away from the vertical plate 7 are fixed on the surface of the limit bar 20. A slide plate 6 is arranged below the surface of one side of the vertical plate 7, so that there is a gap between the limit bar 20 and the upper surface of the conveyor belt 2 to prevent the movement of the conveyor belt 2 from causing damage to the limit bar 20. The slide plate 6 is on the same side as the slide bar 8 and is parallel to each other. A gear bar 9 is arranged on the end of the slide plate 6 that is away from the vertical plate 7. The gear bar 9 slides on the upper surface of the connecting plate 101. A gear 10 is installed on the upper surface of the connecting plate 101 through a bearing. The gear 10 is placed between two gear bars 9 in the same group, and the gear 10 is respectively meshed with the two gear bars 9. The gear 10 and the gear bar 9 cooperate with each other to ensure the synchronous movement of the two limit bars 20 and the consistent distance with the center of the equipment.
[0026] Please refer to Figure 2 and Figure 3 As shown, positioning grooves 801 are evenly opened along the axis on the lower surface of the slide rod 8, and an installation groove 11 is vertically opened at the lower part of the protrusion 5. A limiting slider 13 is slidably installed on the upper part of the installation groove 11. The top of the limiting slider 13 is adapted to the internal size of the positioning groove 801. The cooperation between the two can limit the slide rod 8, thereby ensuring the stability of the position of the limiting strip 20.
[0027] Among them, a convex ring 12 is provided on the inner side of the mounting groove 11, and a connecting rod 14 is provided at the bottom of the limiting slider 13. The connecting rod 14 passes through the convex ring 12, and an extrusion head 15 is provided at the bottom of the connecting rod 14. The bottom of the extrusion head 15 is hemispherical, which can reduce friction. The extrusion head 15 extends downward to the inner side of the side plate 1, and a spring 16 is sleeved on the surface of the connecting rod 14. The top of the spring 16 contacts the lower surface of the convex ring 12, and the bottom of the spring 16 contacts the upper surface of the extrusion head 15. The limiting slider 13, the connecting rod 14 and the extrusion head 15 are an integrated structure to achieve synchronous movement. The downward elastic force of the spring 16 is used to make the extrusion head 15 below always have a downward force, so that the extrusion head 15 is always in contact with the inclined surface of the cone block 18.
[0028] Please refer to Figure 2 and Figure 3 As shown, a control rod 17 is slidably installed on the inner side of the side plate 1, and cone blocks 18 are evenly arranged on the upper surface of the control rod 17. The bottom of the extrusion head 15 contacts the inclined surface of the cone block 18. A control bolt 19 is screwed on one end of the side plate 1, and the end of the control bolt 19 contacts the surface of one end of the control rod 17. The control bolt 19 is screwed on to extrude the control rod 17, thereby realizing the control of multiple extrusion heads 15 on a single side.
[0029] Working principle: First, adjust the distance between the two limit bars 20 according to the size of the magnetic core to be detected. Due to the existence of the spring 16, the extrusion head 15 always has a downward force, so that the arc at the bottom of the extrusion head 15 can always keep in contact with the inclined surface of the cone block 18. The control bolt 19 is screwed inward to effectively squeeze the control rod 17, and then the extrusion head 15 moves up, pushing the limit slider 13 to move up and cooperate with the positioning groove 801 to keep the position of the slide bar 8 stable. Conversely, the control bolt 19 can be screwed outward during adjustment, and the control rod 17 is no longer squeezed. Using multiple springs 16, The limit slider 13 moves downward and no longer cooperates with the positioning groove 801, and can realize single control of whether multiple slide bars 8 on the same side are limited. After releasing the limit on the slide bars 8 on both sides, push the limit bar 20 on one side to move, and the lateral movement of the slide bar 8 can make the vertical plate 7 and the slide plate 6 move synchronously, and then through the mutual engagement of the gear rod 9 and the gear 10, the two limit bars 20 are guaranteed to move synchronously, so that the two limit bars 20 are at the same distance from the center of the equipment to ensure that the magnetic core is placed in the center position of the equipment during the continuous movement detection process. After the adjustment is completed, the slide bar 8 is limited by the above-mentioned distance to keep the position of the limit bar 20 fixed.
[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
