[0025] Embodiment 2:

[0026] Figure 1-5An auxiliary positioning device for crucible drying according to an embodiment of the utility model is shown, which comprises: two limiting grooves 2 arranged in the inner cavity of a hot air drying box 1, the two limiting grooves 2 are respectively located on the left and right sides of the inner cavity of the hot air drying box 1, the inner cavity of the limiting groove 2 is fixedly connected with a limiting plate 3, a circular hole is provided on the surface of the limiting plate 3, a support block 4 is slidably connected with the surface of the limiting plate 3, the support block 4 is slidably connected with the inner cavity of the limiting groove 2, a hole is provided on the side opposite to the limiting plate 3 of the support block 4, a fixing tube 5 is fixedly connected with the inner cavity of the hole, a ball 6 is rotatably connected with the end of the fixing tube 5 opposite to the limiting plate 3, a spring 7 is welded on the inner wall of the fixing tube 5, and a fixing bar 14 is opposite to the limiting groove 2 One side of the casing is fixedly connected to two clamping limit plates 16. Through the setting of the clamping limit plates 16, the limit tube 11 can be clamped and limited when the arc limit head 13 clamps and fixes the concave limit block 15, so that the arc limit head 13 can assist in fixing the limit groove 2 when clamping and supporting the limit groove 2. The clamping limit plates 16 are respectively located on the upper and lower sides of the concave limit block 15, and the surface of the concave limit block 15 is embedded between the two arc limit heads 13. The surface of the limit tube 11 is located between the two clamping limit plates 16. The limit groove 2 is fixedly connected to the inner cavity of the hot air drying box 1 through the arc limit head 13, the concave limit block 15 and the clamping limit plate 16.

[0027] Working principle: When the utility model is used, the user fixes the fixing strip 10 to the left and right sides of the inner cavity of the hot air drying box 1, and then pushes the limiting groove 2 and the fixing strip 2 14 toward the direction of the fixing strip 10. When the surface of the concave limiting block 15 touches the surface of the arc limiting head 13, continue to press inward. At this time, under the special shape of the concave limiting block 15, the arc limiting heads 13 on both sides are pushed to slide back to each other. When the clamping limiting plate 16 contacts the surface of the fixing strip 10, the arc limiting heads 13 are acted on by the rebound force of the spring block 12, and the two arc limiting heads 13 return to their original positions, and clamp the surface of the concave limiting block 15. Then the limiting groove 2 is installed, and then the crucible is placed in the hot air drying. The inner cavity of the box 1 is placed on the concave surface of the concave limiting plate 9, and then the concave limiting plate 9 is moved to drive the fixed block 8 and the supporting block 4 to slide on the surface of the limiting plate 3. At the same time, the ball 6 rollingly connected to the inner wall of the hole of the supporting block 4 will roll in the circular hole on the surface of the limiting plate 3 under the limitation and support of the fixed tube 5 and the spring 7, and stop moving when the concave limiting plate 9 slides to the appropriate position. At this time, under the action of the circular hole and the ball 6, the supporting block 4 is limited, and then the concave limiting plate 9 is used to position and clamp the crucible, so that the position of the crucible in the inner cavity of the hot air drying box 1 can be clamped and fixed when the crucible is dried, so as to avoid the crucible from shaking during the drying process of the hot air drying box 1, resulting in uneven heating on the surface of the crucible.

[0028] In summary, the auxiliary positioning device for crucible drying drives the fixed block 8 and the support block 4 to slide on the surface of the limiting plate 3 by moving the concave limiting plate 9, and drives the ball 6 to roll in the circular hole on the surface of the limiting plate 3, so that the concave limiting plate 9 can position and clamp the crucible, thereby avoiding the possibility of the crucible shaking during the drying process of the hot air drying box 1, which causes uneven heating of the crucible surface.
