Problems solved by technology

[0002] In the process of gear processing, there is a quenching process, which requires special quenching equipment to quench the gears. The existing quenching equipment is usually that the gears are directly fixed on the gear mounting table, and the fixed gear is translated and rotated by the mobile quenching tool. The gear is quenched, which is troublesome, which affects the quenching efficiency, and the uniformity and reliability of the tooth surface quenching cannot be guaranteed;

[0003] The general gears of the existing quenching equipment are installed on the gear installation turntable of the quenching equipment. The gear installation turntable drives the gear to rotate to the designated position and then performs quenching operation. Since the gear installation turntable can rotate freely, it is easy to cause the gear position during the quenching operation. Deviation not only affects the quenching efficiency, but also affects the quenching effect and product quality;

[0004] Conventional gears are directly installed on the gear installation turntable of the quenching equipment for quenching operation. However, since the shaft teeth have gear shafts on both sides of the gear, during the rotation process, the gear shaft will generate outward centrifugal force. The gear mounting plate fixes the gears, and the installation stability of the gears cannot be guaranteed. During the quenching operation, it is easy to cause the position of the gears to deviate, which not only affects the quenching efficiency, but also affects the quenching effect and product quality;

[0005] Conventional quenching equipment, because the gear only rotates during the quenching process, it cannot be moved. In order to ensure that the gear installation station is spacious and convenient for gear disassembly, there is often a certain distance between the original position of the quenching tool and the gear installation station. Moreover, when the thickness of some gears is thick or the tooth surface is large, it is difficult to match the position between the quenching tool and the quenching surface of the gear. Therefore, it is necessary for the quenching tool on the quenching equipment to be able to move in all directions, so that Quenching the gears;

[0006] The cooling mechanism of the existing gear quenching equipment is usually fixed-point cooling. When cooling a thicker and larger gear, the surface temperature of the gear will not be cooled uniformly, which will affect the quenching effect and product quality. The process of cooling the gear may also cause the coolant to splash, get dirty, wet, or even damage other parts of the quenching machine, which will affect the service life of the quenching machine;

[0007] Moreover, during the cooling process of the cooling mechanism, the coolant is sprayed onto the gear with a certain impact force, so it is easy to cause the coolant to splash, get dirty, wet, or even damage other parts of the quenching machine, affecting the quenching machine. service life, and the exhausted coolant also flows to the frame of the quenching machine, or directly drops to the ground, which not only cannot be reused, but also increases the difficulty of cleaning;

[0008] Moreover, after the gears are quenched and cooled, some impurities such as coolant usually remain in the tooth grooves. If they are not cleaned in time, they will be adsorbed in the tooth grooves for a long time, which will not only affect the quenching effect of the gears, but also affect the quality of the gears. Long, it will also cause the gear to rust and affect the service life of the gear
