Description

Technical Field

[0002] With the rapid development of the automobile industry, the quality and performance requirements of automobile parts are increasing day by day. As an important process, surface hardening treatment plays a key role in enhancing the wear resistance, hardness and service life of automobile parts.

[0003] In the current surface hardening treatment of automobile parts, carburizing treatment and other methods are usually used. General treatment equipment includes a carburizing tank, a gas input pipeline, etc. The surface hardening is achieved by placing the parts in the carburizing tank, passing the carburizing gas, and heating the parts.

[0004] However, the existing surface hardening treatment devices for automobile parts still have some shortcomings in practical applications. One of the more prominent problems is that during the carburizing process, due to the lack of an effective stirring device for automobile parts, the carburizing gas often cannot be evenly distributed around the parts. This leads to inconsistent contact between different parts of the part surface and the carburizing gas, resulting in uneven carburizing effect. Some areas may be insufficiently carburized, and the hardness and wear resistance may not meet the expected requirements; while in other areas, excessive carburization may affect the overall performance and quality of the parts, thereby shortening the service life of the parts. Therefore, a new type of automobile part surface hardening treatment machine is proposed to solve the above problems. Utility Model Content

The outer sides of the two gears 17 are meshed with the inner sides of the gear ring 27, and the outer sides of the gears 17 are meshed with the outer sides of the gears 16. A cooling chamber 11 is fixedly connected to one side of the top of the base 1. A feed pipe 5, a carburizing gas pipe 6, a discharge pipe 8 and a vacuum pump 3 are respectively fixedly connected to the outer sides of the carburizing tank body 2. The other end of the discharge pipe 8 is fixedly connected to the outside of the quenching chamber 9. The output end of the vacuum pump 3 is connected to the carburizing tank body 2 through a pipeline. A pressure gauge 4 is fixedly connected to the top of the carburizing tank body 2. An insulation layer 14 is provided on the inner bottom and the inner wall of the carburizing tank body 2.

[0034] Specifically, the base 1 serves as the supporting structure of the entire processing machine to ensure that other components can be stably installed and operated. The carburizing tank body 2 provides a closed environment for carburizing treatment, so that the carburizing gas can act evenly on the surface of the parts, thereby performing carburizing treatment. The motor 17 provides power for the stirring mechanism in the carburizing tank body 2 to ensure that the carburizing gas can be evenly distributed around the parts. The connecting rod 15 connects the motor 17 and the gear 16 to transmit the rotational power of the motor to the gear 16. The gear 16 transmits the rotational power by meshing with the gear 2 17, driving the stirring plate 19 to stir, so that the carburizing gas is evenly distributed. The chute 20 provides a sliding track for the connecting block 21 to ensure that the connecting rod 18 and the stirring plate 19 can rotate smoothly. The connecting block 21 and the connecting rod 18 connect the gear 2 17 and the stirring plate 19 to realize the rotation of the stirring plate 19. The gear 2 17 meshes with the gear 16 and the ring gear 27, and the stirring plate 19 can rotate according to a predetermined trajectory through the transmission between the gears. The stirring plate 19 rotates in the carburizing tank body 2 to ensure that the carburizing gas can be evenly distributed around the parts and improve the carburizing effect. The gear ring 27 provides a fixed meshing point for the gear 2 17 to ensure that the gear 2 17 can rotate according to a predetermined trajectory. The cooling chamber 11 provides a closed environment for cooling the parts that have been carburized and quenched. The feed pipe 5, the carburizing gas pipe 6, and the discharge pipe 8 are respectively used to transport parts, carburizing gas and discharge carburized parts into the carburizing tank body 2. Before the carburizing treatment, the vacuum pump 3 is connected to the carburizing tank body 2 through a pipeline to remove the air in the tank body and create a vacuum environment, which is conducive to the carburizing reaction. The pressure gauge 4 monitors the pressure in the carburizing tank body 2 to ensure that the carburizing process is carried out under appropriate pressure conditions. The insulation layer 14 is arranged on the inner bottom and inner side wall of the carburizing tank body 2 to keep the temperature in the tank body stable and ensure the effect of the carburizing treatment.

[0035] Reference Figure 2 , Figure 5 and Figure 6 A cooling fan 12 is fixedly connected to one side of the top of the base 1, and a connecting pipe 13 is fixedly connected to the output end of the cooling fan 12. The other end of the connecting pipe 13 passes through the top of the cooling chamber 11 and is fixedly connected to a cooling shell 22. An auxiliary component is arranged outside the cooling chamber 11, and the auxiliary component is used to assist the cooling shell 22. The auxiliary component includes two limit grooves 23 and a motor 25. The two limit grooves 23 are arranged inside the cooling chamber 11, and the outside of the motor 25 is fixedly connected to the outside of the cooling chamber 11. An eccentric wheel 26 is fixedly connected to the output end of the motor 25, and a connecting block 28 is rotatably connected to the eccentric shaft pin of the eccentric wheel 26. The other end of the connecting block 28 is rotatably connected to a fixed block 24, and the outside of the fixed block 24 is fixedly connected to the outside of the cooling shell 22. Both sides of the cooling shell 22 are slidably connected to the inner walls of the corresponding limit grooves 23.

[0036] Specifically, the air cooler 12 provides cold air for the cooling shell 22 in the cooling chamber 11 to reduce the temperature of the parts. The connecting pipe 13 connects the air cooler 12 and the cooling shell 22, and guides the cold air from the air cooler 12 to the cooling shell 22. The cooling shell 22 cools the parts in the cooling chamber 11 and reduces the temperature of the parts by the cold air. The motor 25 is the power source of the auxiliary component, and it is firmly mounted on the outside of the cooling chamber 11. When the motor 25 is running, it drives the eccentric wheel 26 to rotate. Due to the eccentricity of the eccentric wheel 26, when it rotates, the connecting block 28 will reciprocate under the drive of the eccentric shaft pin. The movement of the connecting block 28 can drive the fixed block 24 to move. When the connecting block 28 moves under the drive of the eccentric wheel 26, it will drive the cooling shell 22 to move together through the fixed block 24. The two sides of the cooling shell 22 are designed to slide on the inner wall of the limit groove 23. This design ensures that the cooling shell 22 can move along the trajectory of the limiting groove 23 when swinging, thereby preventing the cooling shell 22 from shaking or deviating from the predetermined trajectory.

[0037] Reference Figure 1 and Figure 2 The top of the cooling chamber 11 is fixedly connected to the quenching chamber 9, the bottom of the quenching chamber 9 is fixedly connected to the discharge pipe 10, and the other end of the discharge pipe 10 is fixedly connected to the top of the cooling chamber 11.

[0038] Specifically, the quenching chamber 9 is used to quench the carburized parts to improve the hardness and wear resistance of the parts; the discharge pipe 10 is used to discharge the quenched parts from the quenching chamber 9 into the cooling chamber 11 for cooling.

[0039] Working principle: Automobile parts enter the carburizing tank body 2 through the feed pipe 5. Carburizing gas enters the carburizing tank body 2 through the carburizing gas pipe 6, and contacts the parts for carburizing treatment. Then the exhaust gas in the carburizing tank body 2 is discharged to a suitable vacuum state through the vacuum pump 3. Then the motor 17 is started to drive the connecting rod 15 and the gear 16 to rotate. Since the gear 16 is meshed with the two gears 2 17, and the gear 2 17 is meshed with the ring gear 27, the gear 2 17 will drive the connecting rod 18 and the stirring plate 19 to rotate in the carburizing tank body 2, ensuring that the carburizing gas is evenly distributed around the parts and improving the carburizing effect. Then it enters the quenching chamber 9 through the discharge pipe 18, and quenching in the quenching chamber 9 improves the hardness and wear resistance of the parts. Then it enters the cooling chamber 11 through the discharge pipe 2 10, and at the same time, the air cooler 12 is started to provide cold air to the cooling shell 22 through the connection pipe 13, and the temperature of the parts is reduced under the action of multiple nozzles on the cooling shell 22. When the motor 25 is started, it drives the eccentric wheel 26 to rotate. When the eccentric wheel 26 rotates, due to the existence of the eccentricity, it drives the connecting block 28 to swing back and forth. When the connecting block 28 swings, it drives the cooling shell 22 to swing back and forth in the limiting groove 23 through the fixing block 24, thereby enhancing the cooling effect on the parts.
