Description

TECHNICAL FIELD

[0001] The utility model relates to work piece detection technical field, concretely is a kind of detection tool for metal fitting production. BACKGROUND

[0002] In the production process of various workpieces, the sealing of the workpiece often needs to be tested to ensure that the workpiece has good sealing. The conventional sealing test method mostly uses air blowing to the workpiece, and detects the liquid level drop speed in the pipe by using the capillary effect of the capillary tube to obtain the sealing grade of the workpiece.

[0003] The present invention with publication number CN209727386U discloses a workpiece sealing detection device. The liquid level adjusting mechanism cooperates with the detection mechanism to realize automatic switching between the three stations of plugging, air blowing and air suction. When the liquid level in the pipeline does not rise to the camera surface or there are bubbles in the liquid, the liquid level in the pipeline is automatically adjusted. This not only improves the working efficiency of the device and reduces the labor cost, but also avoids human error, realizes more accurate detection, and solves the problem that when the sealing of the measured workpiece is poor, a large amount of gas passes through the capillary tube, the wet pipe wall becomes relatively dry, the inner wall resistance of the capillary tube increases, the surface tension of the rising liquid level reaches the equilibrium state at a low position, and the liquid level in the capillary tube cannot return to the original position at the end of the test, which is lower than the camera capture range, resulting in that the test cannot be performed again, and manual intervention is required to adjust the liquid level height to a position above the camera surface. This adjustment time seriously affects the test efficiency, and causes high cost, poor precision or human error.

[0004] The existing workpiece sealing detection device needs to inject gas into the detection workpiece during use. When the workpiece has a small leakage, the released gas is less, which makes it difficult to be found, and the rapid detection of the sealing of the metal fitting cannot be realized. To solve the above problems, a detection tool for metal fitting production is proposed in the present application. UTILITY MODEL CONTENTS
