Detailed Description

In order that the manner in which the above recited features of the present utility model can be better understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The ferrite core length sorting device as shown in fig. 1-4 comprises a base plate 1, a fixed strip 2, a movable strip 3, a fixed block 4, a guide rod 5, a micrometer 6, a micro switch 7 and a prompting mechanism 8. The base plate 1 is rectangular plate, the fixing strip 2 is fixedly arranged on the lower side of the base plate 1 through bolts, and the base plate 1 is obliquely arranged at an angle of 15-30 degrees, so that the magnetic core can be contacted with the fixing strip 2 by means of gravity, and the parallel and level of the lower end of the magnetic core is ensured.

The two fixing blocks 4 are fixed on the upper side of the base plate 1 by bolts, and connecting lines of the two fixing blocks 4 are arranged parallel to the fixing strips 2. The side of the fixed block 4 is provided with a guide hole, and the axis of the guide hole is perpendicular to the side wall of the fixed strip 2. The two guide rods 5 are respectively and slidably arranged in the guide holes through linear bearings, and the lower ends of the two guide rods 5 are fixedly connected with the movable strip 3, so that the movable strip 3 is parallel to the fixed strip 2 and can be close to or far away from the fixed strip 2 along the surface of the substrate 1. The micrometer 6 is fixed on the base plate 1, and the micrometer 6 is located between two fixed blocks 4, the telescopic end of the micrometer 6 is connected with the middle part of the movable strip 3 through a bearing, and the micrometer 6 can be rotated to achieve accurate adjustment of the distance between the fixed strip 2 and the movable strip 3. Wherein, the upper end of the guide rod 5 is fixed with an anti-falling block 51, thereby preventing the movable bar 3 from falling off. When the magnetic core is used, the micrometer 6 is adjusted to enable the distance between the fixed strip 2 and the movable strip 3 to be equal to the maximum allowable length of the magnetic core, namely the design length plus the maximum positive tolerance, and if the magnetic core cannot be inserted between the fixed strip 2 and the movable strip, the length of the magnetic core exceeds the maximum positive tolerance range.

As shown in fig. 1-4, the right end of the movable bar 3 is provided with a mounting groove 31, two sides of the mounting groove 31 are provided with symmetrical groove holes 32, and the length direction of the groove holes 32 is perpendicular to the length direction of the movable bar 3, so that the distance between the micro switch 7 extending into the fixed bar 2 and the movable bar 3 is adjustable. The microswitch 7 is fixed in the mounting groove 31 by a bolt so that the trigger piece 71 of the microswitch 7 faces the fixing bar 2. Preferably, the slot-shaped hole 32 on the lower side of the moving bar 3 is a counter bore, so as to avoid interference between the bolt and the base plate 1.

When the magnetic core sliding device is used, the distance between the micro switch 7 extending into the fixed strip 2 and the movable strip 3 is adjusted, so that the triggering depth of the micro switch 7 is equal to the sum of the absolute values of the maximum positive tolerance and the maximum negative tolerance of the magnetic core, and if the magnetic core cannot trigger the micro switch when sliding along the fixed strip 2 and the movable strip 3, the magnetic core is proved to be shorter than the minimum allowable length of the magnetic core.
