Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment tooling and relates to a tooling for high-frequency heat treatment of a driving shaft of an automobile air-conditioning compressor. Background Art

[0002] In the manufacturing process of the drive shaft of the automotive air-conditioning compressor, heat treatment is a key process link and plays a vital role in improving its performance. The existing drive shaft heat treatment fixture is a rectangular aluminum block with three fixing screw holes on the right and a positioning hole on the left. After the drive shaft is inserted into the positioning hole, it is directly subjected to high-frequency heat treatment. In the existing drive shaft heat treatment, due to the limitations of the heating method, different parts of the drive shaft may be heated unevenly, which may cause some areas to overheat, while other areas fail to reach the ideal heat treatment temperature, resulting in inconsistent performance of the drive shaft as a whole. Uneven heating may also cause differences in local organizational changes, thereby affecting the hardness distribution of the drive shaft. When the hardness of the drive shaft is uneven, problems such as excessive local wear, deformation, and even breakage will occur during use, seriously affecting its service life and safety. Utility Model Content

[0003] The utility model provides a high-frequency heat treatment tool for a driving shaft, so as to solve the problem of uneven heating of the high-frequency heat treatment of the driving shaft of the existing automobile air-conditioning compressor.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: it includes a base, a longitudinal cylinder, a lifting support plate, a transverse cylinder, a translation support and a clamp, the cylinder body of the longitudinal cylinder is connected to the base, the lifting and retracting rod of the longitudinal cylinder is connected to the lifting support plate, the longitudinal cylinder is used to control the up and down lifting of the lifting support plate, the cylinder body of the transverse cylinder is connected to the lifting support plate, the lifting and retracting rod of the transverse cylinder is connected to the translation support, the transverse cylinder is used to control the left and right translation of the translation support, the translation support is provided with a motor, the motor is connected to the clamp, the clamp is used to clamp the driving shaft that needs to be subjected to high-frequency heat treatment, and the motor is used to control the rotation of the clamp.

[0005] In the above technical solution, a more specific technical solution can also be: a fixed seat is provided at one end of the lifting support plate, and a limit plate is provided at the other end of the lifting support plate. The cylinder body of the transverse cylinder is connected to the fixed seat, and the lifting and retracting rod of the transverse cylinder can extend to the limit plate, and the limit plate is used to limit the translation stroke of the translation support.

[0006] Furthermore: the limit plate is equipped with a limit screw, and the limit screw is aligned with the lifting and retracting rod of the transverse cylinder. The required translation stroke of the translation support can be adjusted by adjusting the length of the limit screw.

[0007] Furthermore: the base is provided with a plurality of guide columns, the lifting support plate is provided with a plurality of guide sleeves matched with the guide columns, the guide columns are installed in the guide sleeves, so that the lifting support plate can be lifted and lowered more smoothly.

[0008] Furthermore: the motor and the fixture are connected via a reducer.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art: by driving the drive shaft to rotate continuously during the heat treatment process through the motor, the problem of uneven heating of the drive shaft in the traditional method can be fundamentally solved. This uniform heating ensures the temperature consistency of each part of the drive shaft, so that the final HRC hardness distribution is more uniform, which greatly improves the overall quality and performance stability of the drive shaft. Whether in high-load operation or complex working conditions, it can show excellent reliability, reduce the risk of failure caused by uneven hardness, and extend the service life of the drive shaft.
