This utility model discloses a quenching device for machining automotive steering ball joints, belonging to the field of steering ball joint machining technology. It includes a frame, with a rotating column vertically mounted at one end of the frame, and a feeding disc fixed to the top of the rotating column. Several sets of slots are provided on the side of the feeding disc. Thus, after the ball is heated, the rotating mechanism drives the feeding disc to rotate. At this time, the ball joint moves synchronously with the feeding disc. As the ball joint moves to the position of the L-shaped unloading plate, the ball will abut against the L-shaped unloading plate, causing the ball joint to disengage from the slots and then fall directly into the quenching pool below for cooling. This technical solution utilizes the self-movement of the rotating feeding disc and a simple structure to achieve automatic unloading. Furthermore, the seamless connection between unloading and quenching / cooling ensures the timeliness of the quenching process, greatly improving production efficiency. In addition, the trajectory and drop position of the ball joint during unloading are controllable, facilitating subsequent collection and processing, further optimizing the overall production process.

This invention provides a differential component module and a cable connector. The differential component module includes at least two differential components and a middle housing. The middle housing has at least two first mounting slots, each for accommodating and positioning one of the differential components. At least two of the differential components are fixedly connected to the middle housing to form an integral single-row module. This invention simplifies the installation process by fixing multiple differential components to a middle housing to form an integral single-row module. During subsequent installation, operators can directly manipulate the entire module instead of handling individual differential components one by one. Furthermore, since multiple differential components are fixed as a whole, their swaying amplitude during installation into the housing is significantly reduced, and their position is easily controlled, effectively reducing installation difficulty and improving assembly efficiency and product yield.
