[0002] Bucket teeth are important parts of excavator buckets, used to protect the bucket as a whole and improve the working efficiency of the bucket. In the process of producing bucket teeth, heat treatment is one of the most important processes in the processing. The heat treatment of bucket teeth is to heat the bucket tooth workpiece to a certain temperature to change its crystal structure or dissolve the solid solution, and then quickly cool the bucket tooth to room temperature through oil cooling, water cooling or air cooling. The martensitic structure is formed by rapid cooling, thereby improving the hardness and strength of the bucket tooth.

[0003] In the prior art, there is a bucket tooth heat treatment device and a heat treatment method with announcement number CN18006880A, which include a heating furnace, a cooling pool and a treatment table, wherein a plurality of conveying rollers are provided in the heating furnace and the cooling pool; the treatment table is provided with a plurality of mounting components along its conveying direction, and the mounting frames are symmetrically arranged on both sides of the conveying direction of the treatment table, and the mounting frames on each side include a rotating shaft and an annular rod, and the annular rod is used to pass through the mounting hole of the bucket tooth; the driven wheel has a plurality of shifting teeth evenly distributed along its circumference, and an arc-shaped groove is provided between two adjacent shifting teeth, the driven wheel is fixedly connected to the transmission rod, a plurality of first shifting rods are provided on the transmission rod, and a plurality of second shifting rods are provided on the rotating shaft, and the first shifting rods are used to shift the second shifting rods; the top adjustment plate and the bottom adjustment plate are respectively located on the upper and lower sides of the annular rod; the bucket tooth heat treatment device and the heat treatment method are conducive to uniform heating of the bucket teeth, ensure the heat treatment effect and the stable quality of the bucket teeth, and improve the treatment efficiency.

[0004] However, in the above scheme, since the annular rod is used to pass through the mounting hole of the bucket tooth, the size of the mounting hole of the bucket tooth is larger than the size of the cross-section of the annular rod, the bucket tooth and the annular rod are slidably connected, and the bucket tooth can slide along the annular rod. When using the heat treatment device to perform heat treatment on the bucket tooth, it is necessary to place the annular rod with the bucket tooth installed on the flat rod. During this process, the annular rod is prone to tilt. When the annular rod is tilted, multiple bucket teeth on the annular rod will accumulate at the lower end of the annular rod. During this process, collisions will occur between the bucket teeth. The collisions between the bucket teeth will affect the quality of the bucket teeth to a certain extent. The accumulation of bucket teeth will affect the heating effect, and then affect the heat treatment effect. Summary of the invention
