[0032] Refer to Figure 1 、 Figure 2 A tooling for assisting in wire cutting of a directional single crystal blade provided by the present utility model includes a base 1. The base 1 is used to install other structures and can be assembled with a wire cutting device. A fixed side plate 3 is fixedly connected to the right side of the top of the base 1. A movable side plate 5 is slidably connected to the left side of the top of the base 1. The fixed side plate 3 and the movable side plate 5 are used to install a fixed plate 9. Fixed plates 9 are fixedly connected to one side of the fixed side plate 3 and the movable side plate 5 respectively. The fixed plate 9 is used to install a bolt 7. A bolt 7 is rotatably connected inside the fixed plate 9. Rotating the bolt 7 can adjust the angle of the rotation limiting block 4. The front end of the bolt 7 is fixedly connected to a rotation limiting block 4. The rotation limiting block 4 can clamp and fix the directional single crystal blade. The rotation limiting block 4 is made of steel, and the steel material makes the rotation limiting block 4 have high strength. A corrosion-resistant layer is provided on the outer periphery of the rotation limiting block 4. The corrosion-resistant layer is an electroplated layer, which can effectively reduce the erosion suffered by the rotation limiting block 4. The rear side of the rotation limiting block 4 abuts against the front side of the fixed plate 9. A nut 6 is threadedly connected to the outer periphery of the bolt 7. The nut 6 is used to fix the angle of the rotation limiting block 4. A positioning block 2 is arranged in the middle of the top side of the base 1. The positioning block 2 is arranged on the side where the movable side plate 5 and the fixed side plate 3 face each other. The positioning block 2 is connected to the base 1 through screws and can be removed for replacement. The size and shape of the positioning block 2 conform to the deep root size and shape of the directional single crystal blade, which is convenient for fixing the directional single crystal blade. A wear-resistant layer is provided on the outer periphery of the positioning block 2. The wear-resistant layer is made of a chromium coating, which can reduce the wear suffered by the positioning block 2.
[0033] Refer toFigure 3 , Figure 4 , a movable component is provided at the bottom side of the movable side plate 5. The movable component is used to support the movement of the movable side plate 5. The movable component includes a T-shaped slider 8. The T-shaped slider 8 is fixedly connected to the bottom side of the movable side plate 5. A chute is provided inside the base 1. The T-shaped slider 8 is slidably connected inside the chute. The sliding of the T-shaped slider 8 inside the chute can support the movement of the movable side plate 5. The movement of the movable side plate 5 can adjust the distance between the two rotating limit blocks 4. Two springs 11 are fixedly connected inside the bottom side of the T-shaped slider 8. The springs 11 are used to push the convex blocks 12 to move. One end of each spring 11 is fixedly connected with a convex block 12. A plurality of uniformly distributed grooves 10 are provided inside the base 1. The convex blocks 12 are slidably connected inside the grooves 10. The insertion of the convex blocks 12 into the grooves 10 can fix the position of the movable side plate 5.
[0034] Working principle: Before using this tooling, first install the tooling on the wire cutting equipment. After installation, pull the movable side plate 5 to move leftward to separate the two rotating limit blocks 4. Place the deep root of the directionally solidified single crystal blade on the positioning block 2 so that the positioning block 2 supports and fixes the directionally solidified single crystal blade. Then rotate the bolt 7 to adjust the angle of the rotating limit block 4. After the angle of the rotating limit block 4 is adjusted, rotate the nut 6 so that the nut 6 is in close contact with the rotating limit block 4 against the fixing plate 9 to fix the angle of the rotating limit block 4. Then push the movable side plate 5 to move rightward to drive one of the rotating limit blocks 4 to press against the directionally solidified single crystal blade, so that the two rotating limit blocks 4 clamp and fix the directionally solidified single crystal blade. After the position of the movable side plate 5 is adjusted, the two convex blocks 12 inside the T-shaped slider 8 can be pushed by the two springs 11 to be inserted into the two grooves 10 respectively to fix the position of the movable side plate 5. After the directionally solidified single crystal blade is fixed, wire cutting can be carried out. After the fixing is completed, wire cutting treatment can be carried out.
