[0036] Reference Figure 1 The hemispherical piece 5 of the prior art includes a hemispherical body, an arc-shaped groove 11 is opened on one side of the hemispherical piece 5, an arc-shaped protrusion 9 is formed on the other side of the hemispherical piece 5, a third hole 19 is opened inside the hemispherical piece 5, and a plurality of through holes 20 are provided on the hemispherical piece 5.
[0037] Reference Figure 1 and Figure 2 The prior art hemispherical piece heat treatment tooling includes a connecting rod 1, a lower cover 2 fixed to one end of the connecting rod 1 by a nut, and an upper cover 3 fixed to the other end of the connecting rod 1 by a nut. An installation area 4 is formed between the upper cover 3 and the lower cover 2. Before heat treating the hemispherical piece 5, the lower cover 2 needs to be threadedly connected to one end of the connecting rod 1, the hemispherical pieces 5 are stacked on the lower cover 2, and the upper cover 3 is placed on the stacked hemispherical pieces 5. The upper cover 3 is fixed to the other end of the connecting rod 1 by a threaded connection, and the upper cover 3 and the hemispherical piece 5 are locked tightly by a nut.
[0038] Reference Figure 3 and Figure 4 The utility model discloses a hemispherical piece heat treatment tooling comprising a connecting rod 1, a lower cover 2, and an upper cover 3. The lower cover 2 is threadedly connected to one end of the connecting rod 1, and the upper cover 3 is arranged at the other end of the connecting rod 1. The lower cover 2 is fixed to the connecting rod 1 by a nut. A first hole 6 is opened on the side of the connecting rod 1 close to the upper cover 3. A wedge pin 7 is inserted into the first hole 6. The upper cover 3 is positioned on the connecting rod 1 by the wedge pin 7. An installation area 4 is formed between the upper cover 3 and the lower cover 2. The installation area 4 is used to place the hemispherical piece 5.
[0039] Reference Figure 3 and Figure 4 The lower cover 2 has a first protrusion 10 integrally formed on the side near the mounting area 4. The first protrusion 10 is embedded in the arc-shaped groove 11 in the mounting area 4, making the lower cover 2 and the hemispherical piece 5 fit more tightly and stably. The upper cover 3 has a first groove 8 on the side near the mounting area 4. The arc-shaped protrusion 9 fits into the arc-shaped groove 11, allowing the hemispherical piece 5 to be stacked in the mounting area 4.
[0040] Reference Figure 3 The upper cover 3 is positioned on the connecting rod 1 through the wedge pin 7, so that the hemispherical piece 5 is stably fitted in the installation area 4, thereby achieving the effect that the hemispherical piece 5 is not easily deformed during the heat treatment process.
[0041] Reference Figure 3 The connecting rod 1 has a first hole 6 at one end near the upper cover 3. Before heat treatment, the lower cover 2 is threadedly connected to one end of the connecting rod 1, and the hemispherical pieces 5 are stacked in the installation area 4.
