Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a quenching fixture for gear processing. Background Art

[0002] Gears are an important part of mechanical equipment, used to transmit torque and convert the movement of one shaft into the movement of another shaft. Gears are an important part of automotive parts. In order to ensure the quality and performance of automotive gears, gear quenching is a metal heat treatment process that heats the gears to a certain temperature and then quickly cools them to enhance their hardness and wear resistance. Quenching is essential for the strength and life of gears because quenching can form a layer of hard martensitic structure on the surface of the gears, thereby improving their wear resistance and fatigue resistance.

[0003] After searching, the Chinese patent announcement number is: CN219032280U, which discloses a rapid quenching device for gear processing, including a base, an equipment box, a quenching box and a placement table, and the surface of the placement table is provided with a placement groove. The utility model relates to the field of gear processing technology. The rapid quenching device for gear processing drives the first transmission wheel to rotate by starting the motor, and the first transmission wheel drives the threaded rod to rotate counterclockwise, and the threaded rod drives the placement table to move downward. When the placement table is about to contact the bottom of the quenching box, the first transmission wheel drives the threaded rod to rotate clockwise, and the threaded rod drives the placement table to move upward. When the placement table moves to the top of the quenching box again, the gear quenching is completed, so that the staff can take and place the gear at the top exit of the quenching box, which not only avoids the staff from being scalded, but also avoids the problem that the long clamp is not easy to operate flexibly, resulting in the gear not being stably placed on the placement table and falling into the quenching box. However, in actual use, the above device has the problem that the existing quenching device is difficult to fix gears of different sizes, resulting in the gears easily shifting and slipping during the quenching process, which requires secondary rework and affects processing efficiency.
