Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic valve manufacturing, and in particular relates to an automatic assembly device for automobile hydraulic valves. Background Art

[0002] Automobile hydraulic valves are an important component of the hydraulic system. They are devices used to control the flow and pressure of liquids. According to different functions and application scenarios, hydraulic valves can be divided into many types. Switch valves and proportional valves are the two most common types of hydraulic valves. Proportional valves can adjust the valve opening to the required position by receiving electrical signals to achieve precise regulation of the liquid. Switch valves are mainly used to control the switching and cutoff of the medium, and can be quickly opened or closed when conveying the medium.

[0003] Structurally, both proportional valves and switch valves include a valve body and a valve core. The valve body encapsulates the valve core inside by riveting. Due to the different shapes of proportional valves and switch valves, their clamping methods and riveting positions are also different. Existing processing workshops generally assemble and test proportional valves and switch valves separately. According to the different riveting positions, each type of valve body is even equipped with a production line. In the case of small production volume of various valve bodies, this processing method wastes equipment and space, increases the production cost of the enterprise, and the existing production line still relies on manual methods and adopts semi-automatic methods for assembly and testing, which not only has high labor costs, but also has relatively low detection accuracy and efficiency.
