AI Technical Summary
The existing detection method of opening air-testing holes on the workpiece positioning block has high requirements for the workpiece positioning surface, and the battery tray may deform during the welding process, resulting in unstable detection.
A battery tray airtight detection device is designed, including a support frame, a gas test seat, a gas test rod and a thrust device. The gas test rod is in contact with the workpiece and the annular groove on the gas test rod is detected to be misaligned with the small holes on the gas test seat after it is in place to ensure that the air does not leak, thereby achieving stable airtight detection.
The device has low requirements for the positioning surface of the workpiece, ensuring the stability of airtight detection and avoiding detection failure caused by unstable workpieces.
