Improved aluminum casting airtightness detection device and detection method thereof

Abstract

The invention discloses an improved aluminum casting airtightness detection device and a detection method thereof. The device comprises a workpiece clamping device, an air leakage detection device and an air blowing device, the workpiece clamping device is used for clamping and fixing a workpiece and enabling a connecting seam of the workpiece to be exposed, the air blowing device is used for blowing air into the sealed workpiece, and the detection end of the air leakage detection device is attached to the surface of the connecting seam of the workpiece, and can move relative to the connecting seam of the workpiece, and the moving direction is the extending direction of the connecting seam of the workpiece; the method is different from the conventional method for detecting the air tightness of the aluminum casting by soaking in water, detection is carried out in an external dry environment, marking can be carried out in time when an air leakage point is found, and the error probability is reduced; according to the method, the air leakage condition can be reflected through specific numerical values, and more accurate reference can be provided for aluminum casting process improvement.

Description

Technical field [0001] The present invention relates to the field of aluminum casting detection, and is specifically an improved aluminum casting airtight detection device and a detection method thereof. Background technique [0002] Aluminum castings such as aluminum casting cylinder hoses, such as aluminum-casting cylinder shells, such as the shell, need to be detected, and currently use the aluminum casting housing and soaked in water, in the aluminum casting housing Internal ventilation, by observing that there is no bubble production at the aluminum casting housing connection to determine whether the sealing properties of the aluminum casting housing are good, such as the patent number "CN2020232703.4", name is "aluminum casting automatic detection leakage equipment" The way used in the file, however, this test mode is carried out in water, so there is still the following shortcomings: [0003] 1. The leak point cannot be marked in time, and can only be recorded in advance, ...

AI Technical Summary

Problems solved by technology

[0003] 1. It is impossible to mark the air leakage point in time, so it can only be recorded in advance and marked afterwards;

[0004] 2. The air leakage can only be roughly judged by observing the amount of air bubbles at the air leakage, and cannot provide more accurate reference opinions for process improvement
