The waterproof test fixture of motor shell is to realize the waterproof grade test of motor shell. Test method: use direct test method. Due to the particularity of the motor shell, it is necessary to customize the tooling to install the mold, put the product into the mold, press the upper mold down to fix the product, and conduct the test. The test pressure is 250kPa, the inflation time is 10 seconds, the stabilization time is 10 seconds, the test time is 5 seconds, and the leakage value is 50pA.
Using the double channel air tightness detection equipment, ok/ng products can be detected quickly, and two products can be detected at the same time, with high detection efficiency. Through the waterproof protection of the motor shell, water is prevented from entering the motor to a great extent. Using the traditional bubble water to detect the sealing of the motor shell is inefficient and not intuitive, and some sealing problems are difficult to find. The air tightness testing equipment used will not have this problem, which is a new emerging sealing testing technology. It can efficiently and quickly detect the waterproof grade, sealing degree and other important product quality indicators.
