Abstract

The detection of alternating impact performance of compressed air electric hammer has great significance for studying impact piston motion, analyzing product structure, testing product index and upgrading product performance, and so forth. In order to satisfy the engineering requirement, a new method is put forward to detect impact performance based on electromagnetic induction theory, and a test-bed and a testing system scheme are carried out to measure pneumatic hammer. According to the testing and analysis, the impact performance of impact piston inside the air cylinder and the motion law can be detected and measured, and related impact characteristic parameters, such as impact frequency and impact energy, can be accurately calculated. The pattern of results indicates that the error between the measured value and the theoretically calculated value is within 5%. The convenient and efficient testing method and the accurate and reliable testing result provide further effective basis for performance detection and quality inspection in products.
