Embodiment Construction

[0021] Such as figure 1 , figure 2 The vacuum actuator on-line detection device shown includes a base 1, which is characterized in that a positioning bracket 2 is arranged on the base 1 used in the present invention. Specifically, in order to perform an effective positioning test and obtain a relatively accurate value while satisfying the airtightness, a sealing performance testing component is arranged around the positioning bracket 2 . Moreover, considering the structural requirements of the vacuum actuator to be tested, the sealing performance testing component includes a primary sealing testing component and a secondary sealing testing component to achieve better sealing. Moreover, in order to facilitate the quick reading detection of the on-site production line, a displacement monitoring component is provided at the reserved position of the test interface of the positioning bracket 2 .

[0022] As far as a preferred embodiment of the present invention is concerned, in ...

Abstract

The invention relates to an on-line detection device and a detection method for a vacuum actuator, which is characterized in that a base is provided, a positioning bracket is arranged on the base, and a sealing performance testing component and a displacement monitoring component are arranged around the positioning bracket. During detection, the vacuum actuator is placed on the positioning bracket for positioning, and the vacuum actuator is sealed by using the sealing performance testing component and the displacement monitoring component. Afterwards, the vacuum actuator is inflated step by step to obtain test data. Finally, the sealing performance testing component and the displacement monitoring component are released, and the vacuum actuator is removed. As a result, step-by-step detection can be adopted to obtain the air pressure data inside the vacuum actuator under different working conditions, so as to perform all-round detection and improve the quality of quality inspection. Furthermore, the present invention has a simple structure, and can meet the needs of online detection on the assembly line through the cooperation of subsequent programs.

Description

technical field [0001] The invention relates to a detection device and a detection method thereof, in particular to an online detection device of a vacuum actuator and a detection method thereof. Background technique [0002] Vacuum actuators are commonly used in vehicles at present. When the solenoid valve is opened, under the action of the vacuum degree of the engine inlet, the traction actuator moves in a linear direction, prompting the traction workpiece to perform as required. The workpiece to be executed works under the action of vacuum force. Therefore, the airtightness of the vacuum actuator and the correct operation of the valve determine the working state. Existing detection devices can only detect a single working condition, and cannot realize dynamic working condition detection, which increases the complexity of detection and is not conducive to fast online detection on the assembly line. Moreover, the existing detection device has poor airtightness, and the ac...
