Description

technical field [0001] The present application relates to the technical field of testing equipment, in particular to an airtight testing device and a testing method. Background technique [0002] When some parts are produced, it is usually necessary to take samples to test the airtightness of the parts or to test the airtightness of the samples of the parts. At this time, airtightness testing equipment is usually used. [0003] refer to Figure 6 , is a kind of existing air-tightness testing equipment, is used for testing the product 6 that the bottom is cylindrical, and the top is the plastic jacket, and it comprises machine platform 1, and the press block 13 is arranged on the machine platform 1 by cylinder 12 lifting , the machine platform 1 includes a workbench 11, and an air outlet hole 361 connected to the air pump is opened on the workbench 11. By covering the air outlet hole 361 with the product 6, and after the briquetting block 13 is pressed against the top of the ...

AI Technical Summary

Problems solved by technology

[0004] During the process of implementing this application, the inventors found that there are at least the following problems in this technology: the bottom of the product 6 and the workbench 11 are sealed by contacting the bottom of the product 6, which is prone to occur The problem of unreliable sealing, especially when the bottom of the product 6 is slightly uneven or the workbench 11 is worn, will affect the accuracy of the detection
