AI Technical Summary
Technical Problem
Traditional shell airtightness testing fixtures lack positioning accuracy and are prone to mechanical resonance, resulting in unstable test results.
Method used
The system employs an electric slide rail in conjunction with a moving base, combined with the vertical transmission of the cylinder-driven push rod and sealing cover, and establishes a stable air pressure path through a pressure regulating valve. It also absorbs impact force through a buffer assembly, forming a multi-stage shock absorption system to achieve high-precision positioning and stable detection.
Benefits of technology
It significantly improves detection efficiency and ease of operation, avoids positioning errors, extends device life, and ensures the consistency of detection results.

Abstract
The utility model relates to precise detection equipment technical field discloses a kind of shell airtightness detection frock, including transport component, the transport component includes control cabinet, the central position at the top of control cabinet is fixedly connected with electric slide rail, the top of control cabinet is fixedly connected with seal cover, the outer surface of electric slide rail is slidably installed with moving seat, the top of moving seat is fixedly connected with placing plate.The utility model sets up top connecting plate at the bottom of sealing cap, and the impact force when air cylinder is pressed down is effectively absorbed by being linked with limit stop along limit frame and cooperating with the elastic buffer effect of spring damper;Main connecting rod is used as lever fulcrum, and converts horizontal displacement into longitudinal buffer stroke, forms multistage damping system, both guarantees the high-precision fit of sealing cap and connecting deflation rod, and also prevents equipment wear or workpiece deviation caused by rigid impact, thereby prolongs the service life of device and ensures the consistency of detection result.
