Abstract:

In this paper, the existing problems in the detection process of the impact test of portable fire extinguishers are comprehensively summarized and analyzed. Combined with the requirements of the national standard for the impact test of the fire extinguisher operating mechanism, a set of impact test device is designed by using the advanced PLC control system, three jaw self- centring chucks and other mechatronics integration technologies. The device realizes the full-automatic impact test on the operating mechanism of the portable fire extinguisher. Actual usage indicates that the device is safer, improves the accuracy of the test effectively, and reduces the labor intensity.  

Key words: portable fire extinguisher, impact test, mechatronics technology
