Description

Technical Field

[0001] The utility model relates to a core assembly tool for casting, in particular to a bridge housing coated sand core assembly tool. Background Art

[0002] Due to the large volume and heavy weight of the bridge housing, two workers are required to cooperate in lifting the bridge housing core to the assembly workbench when assembling it, so that the bridge housing coated sand core can be assembled. In this process, since the core is assembled in half, it is easy to cause eccentricity during core assembly, resulting in core deviation during core placement, which requires the production line to take out the core and re-place it, affecting the production rhythm and reducing production efficiency. In order to ensure that the core is assembled in place and the combined dimensions before core placement are all qualified cores, this tooling platform is used to combine and inspect the cores.

[0019] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0020] For example, see Figures 1-4 A bridge housing coated sand core assembly tooling includes a base frame 1, support legs 2 and a base plate 4. Support legs 2 are provided at the bottom of the base frame 1, and limit plates 3 are respectively provided on both sides of the base frame 1. The base plate 4 is connected to the base frame 1 by bolts, and a first mounting plate 5 is connected to both ends of the base plate 4 by bolts. A support block 6 is provided on the top of the first mounting plate 5, and a limiting groove 7 is dug at the top of the support block 6. A positioning block 12 is provided in the middle of the base plate 4, and limiting components are respectively provided on both sides of the positioning block 12.

[0021] There are three positioning blocks 12 , which are longitudinally distributed at the middle position of the top surface of the bottom plate 4 , and the spacing between adjacent positioning blocks 12 is the same.

[0022] Insertion holes 8 are respectively dug on both sides of the positioning block 12, and there are two insertion holes 8 on each side, which are respectively located outside the middle of the adjacent positioning blocks 12, and a limiting component is provided above the insertion holes 8.

[0023] The limiting assembly consists of a positioning block 9 and a U-shaped groove plate 10. The positioning block 9 is fixed to the outside of the socket 8 by bolts. An insert block is provided at the position corresponding to the socket 8 at the bottom of the positioning block 9. A U-shaped groove plate 10 is provided above the positioning block 9. A displacement plate 11 is inserted into the U-shaped groove plate 10 and fixed by bolts.

[0024] There are two supporting blocks 6 on the first mounting plate 5 , and the positions of the supporting blocks 6 on the left and right sides of the bottom plate 4 correspond to each other.

[0025] A tightening bolt is provided on the outside of the limiting plate 3 .

[0026] In the above description, the bottom plate is displaced to the middle position of the top of the chassis and is fixed by bolts on the outside of the limit plate.

[0027] In the above description, there are four groups of limiting components, which are distributed in pairs on both sides of the positioning block, that is, the limiting components are located at the side positions of the middle parts of two adjacent positioning blocks.

[0028] In the above description, the inner diameter of the limiting groove is 0.2 mm larger than the outer diameter of the hot core neck.

[0029] In the above description, the distance from the bottom of the arc groove to the bottom plate is equal to the distance from the bottom of the core neck to the core lower plane, thereby ensuring that the core necks after assembly are coaxial and at the same height, and ensuring the coaxiality of the corresponding holes at both ends of the casting blank.
