[0002] In the current vehicle braking system, the ball joint on the brake pedal arm and the booster push rod usually adopts a ball cage structure, refer to "CN217074298U-A connection structure between the brake pedal arm and the booster".

[0003] The cage structure consists of a cage bracket, a metal bowl, and a plastic base. The plastic base snaps into the cage bracket cavity, and the metal bowl is installed between the plastic base and the cage bracket. The ball head on the booster push rod is installed in the assembly space formed by the plastic base and the metal bowl. To prevent excessive friction at the contact point between the metal bowl and the ball head, which can cause wear and abnormal noise, grease is generally applied to the friction pair.

[0004] Currently, CVJ cages on production lines are primarily lubricated manually, with workers applying lubricating oil to the inner surface of the metal bowl using a brush. Due to inconsistent force and brush wear, the amount of oil applied to the CVJ cage is difficult to quantify, making quality control difficult. Furthermore, deformation of the brush head can cause the brush to become caught on the plastic base's claws when removed, reducing assembly efficiency. Summary of the Invention

[0007] The above technical solution is further limited. The structure of the rotary positioning platform includes a rotary cylinder, a fixed seat and a ball cage positioning seat. The rotary cylinder is fixed on the base plate. The fixed seat is fixedly connected to the rotary platform of the rotary cylinder. The ball cage positioning seat is detachably connected to the fixed seat. A ball cage positioning groove is provided at the center of the ball cage positioning seat.

[0009] The above technical solution is further limited. The structure of the oiling component includes a hollow rod and an oiling head. The upper end of the hollow rod is connected to the oil outlet end of the metering valve in an interference fit manner. The inner cavity of the lower end of the hollow rod is a conical cavity that gradually shrinks from top to bottom. The oil inlet end of the oiling head is fixedly connected to the lower end of the hollow rod.

[0010] The above technical solution is further defined as follows: the structure of the oiling head includes a disc, an oil inlet hole is provided on the outer side surface of the upper end of the disc, an oil outlet groove is provided on the outer side surface of the lower end of the disc, and the oil inlet hole and the oil outlet groove are connected through the cavity of the disc.

[0011] Beneficial effects: 1) The amount of oil applied to the ball cage can be quantified: This design uses a grease metering valve to control the amount of oil applied, avoiding the problem of manual oiling that cannot be quantified; the oiling component can be directly extended into the ball cage, and the grease can be evenly applied to the entire bowl surface to avoid excessive or insufficient oiling areas; 2) Improved work efficiency: This design uses a metering valve and a rotary positioning table for coordinated oiling, which significantly improves efficiency compared to manual oiling.
