气动工具在采矿、建筑、国防工程中有广泛的应用。近年来,大型气动工具发展尤为迅速。装夹在挖掘机上的破碎冲击器的冲击能的数值已高达350公斤力·米。而做为出厂检验的设备——冲击能测试装置,过去却只能测试20公斤力·米以下的小型气动工具。为了更好的保证出厂产品的性能和质量,我们研制了能测试冲击能为50～350公斤力·米的测试装置。本文扼要的介绍这种新型的冲击能测试装置的工作原理、结构、主要参数的确定和测试方法。某厂生产的FP-50型破碎冲击器其冲击能为50公斤力·米。钎头往复动作频率为
Pneumatic tools in mining, construction, defense projects have a wide range of applications. In recent years, the development of large-scale pneumatic tools is particularly rapid. The impact energy of the broken impactor mounted on the excavator has been as high as 350 kgf-m. As a factory inspection equipment - impact energy test device, but in the past only tested 20 kg power meters below the small pneumatic tools. In order to better guarantee the performance and quality of manufactured products, we have developed a test device capable of testing impact energy of 50 to 350 kgfm. This article briefly introduces the working principle, structure, determination of the main parameters and test methods for this new type of impact energy testing device. A plant produced FP-50 type of impactor impact energy of 50 kgf m. Bit reciprocating action frequency is
