Description

Technical Field

[0001] This utility model relates to the field of quenching technology for ball cage-type parts, specifically to a dual-station quenching device for the inner cavity and inner spline of a ball cage. Background Technology

[0002] The CV joint, also known as a constant velocity joint, is an important component in a car's transmission system. Its function is to transmit the engine's power from the transmission to the drive wheels, enabling the car to travel at high speeds.

[0003] There are two types of CV joints commonly used in passenger cars. One is the fixed CV joint, which is characterized by the fact that the driving shaft can only rotate relative to the driven shaft and will not produce axial displacement during the torque transmission process. It is usually used near the wheels and is what we often call the outer CV joint. The other is the telescopic CV joint, which is characterized by the fact that the driving shaft can not only rotate relative to the driven shaft but also produce axial displacement during the torque transmission process. It is usually used near the drive axle and is what we often call the inner CV joint.

[0004] During vehicle operation, the CV joint transmits heavy driving torque, requiring high transmission precision due to the heavy load. The inner cavity and internal splines of the CV joint bear significant loads during vehicle operation, making their surfaces prone to wear. Therefore, the surfaces of the inner cavity and internal spline areas of the CV joint are required to have certain strength and toughness, high fatigue limit and resistance to repeated impacts, as well as a certain degree of hardness and wear resistance.

[0005] Hardening the inner cavity and spline area of ​​the ball cage can significantly improve its mechanical properties and service life. However, traditional hardening techniques have the following limitations:

[0006] 1. Low efficiency: Single-station quenching requires step-by-step processing of the inner cavity and internal spline, which is time-consuming when switching processes and makes it difficult to achieve synchronous processing;

[0007] 2. Poor precision control: It is difficult to achieve precise positioning of the ball cage, which affects the quenching effect. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a dual-station quenching device for the inner cavity and inner spline of a ball cage. The two stations quench two parts of the ball cage-type part respectively, which greatly improves the quenching efficiency and achieves good quenching results.

[0009] To achieve the above objectives, the present invention provides a dual-station quenching device for the ball cage inner cavity and inner spline, comprising:

[0017] Preferably, the load moving platform is driven by a third motor to move the second ball screw up and down on the second linear guide.

[0018] Preferably, both the first and second ball cage temporary storage stations are equipped with fixed seats and clamps on the fixed seats to hold the ball cages.

[0022] Preferably, the rotary swing arm robot assembly clamps and transports the ball cage to the left quenching station for internal cavity quenching. After quenching, the ball cage is transported and placed in the first ball cage temporary storage station, and then the ball cage is transferred to the second ball cage temporary storage station for internal spline quenching via the right quenching station.

[0023] Preferably, the ball cage is transferred from the first ball cage temporary storage station to the second ball cage temporary storage station using an automatic clamping tool.

[0024] Preferably, the transfer of the ball cage from the first ball cage temporary storage station to the second ball cage temporary storage station is done manually.
