Description

TECHNICAL FIELD

[0002] The bucket tooth is an important component of the excavator bucket, and is used for protecting the whole excavator bucket and improving the working efficiency of the excavator bucket. In the production process of the bucket tooth, heat treatment is one of the most important processes in the machining process. The heat treatment of the bucket tooth is to heat the bucket tooth workpiece to a certain temperature to change the crystal structure or dissolve the solid solution, and then rapidly cool the bucket tooth to room temperature through oil cooling, water cooling or air cooling, so as to form martensite structure in the form of rapid cooling, thereby improving the hardness and strength of the bucket tooth.

[0003] In the prior art, a bucket tooth heat treatment device and a heat treatment method are disclosed in CN18006880A, which comprises a heating furnace, a cooling pool and a treatment table. A plurality of conveying rollers are arranged in the heating furnace and the cooling pool. A plurality of mounting assemblies are arranged on the treatment table along the conveying direction of the treatment table. The mounting racks are symmetrically arranged on both sides of the conveying direction of the treatment table. Each mounting rack comprises a rotating shaft and an annular rod. The annular rod is used for penetrating through the mounting hole of the bucket tooth. The driven wheel has a plurality of shifting teeth which are uniformly distributed along the circumferential direction of the driven wheel. The driven wheel is fixedly connected with a transmission rod. A plurality of first shifting rods are arranged on the transmission rod. A plurality of second shifting rods are arranged on the rotating shaft. The first shifting rods are used for shifting the second shifting rods. The top adjusting plate and the bottom adjusting plate are respectively arranged on the upper side and the lower side of the annular rod. The bucket tooth heat treatment device and the heat treatment method are beneficial to uniform heating of the bucket tooth, ensure the heat treatment effect and the quality stability of the bucket tooth, and improve the processing efficiency.

[0004] However, in the above-mentioned scheme, since the annular rod is used for penetrating through the mounting hole of the bucket tooth, the size of the mounting hole of the bucket tooth is greater than the size of the cross section of the annular rod. The bucket tooth and the annular rod are in sliding connection. The bucket tooth can slide along the annular rod. When the bucket tooth is heat treated by using the heat treatment device, the annular rod on which the bucket tooth is mounted needs to be placed on the flat rod. In this process, the annular rod is prone to tilting. When the annular rod tilts, a plurality of bucket teeth on the annular rod will be stacked at the low end of the annular rod. In this process, the bucket teeth will collide with each other, which will affect the quality of the bucket teeth to a certain extent. The stacking of the bucket teeth will affect the heating effect, and further affect the heat treatment effect. SUMMARY
