Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear processing device with a cleaning function. Background Technique

[0002] Gear quenching is one of the key steps in the gear heat treatment process. Its purpose is to change the organizational structure and properties of the gear by controlling the heating and cooling process of the gear within a certain temperature range, so as to improve the hardness, strength and wear resistance of the gear. Before gear heat treatment, pretreatment and cleaning work need to be carried out.

[0003] Cleaning is to remove grease, dust and impurities on the gear surface through cleaning agents and solvents to ensure the quality of subsequent heat treatment. At present, the pretreatment and cleaning process and the gear quenching process need to be carried out on different equipment, and the gear needs to be loaded and unloaded back and forth. This solution provides a gear processing device with a cleaning function, which combines the cleaning structure and the quenching structure on the same processing device.
