通过对J23－100型曲柄压力机的转键式刚性高合器的结构原理和受力分析，提出直接利用转键本身作为测力传感器的弹性元件，进行压力机的冲击力测试方法。
Through the structural principle and force analysis of J23-100 Crank Press, the author puts forward the method of testing the impact force of the press by using the transfer key itself as the elastic element of the load cell.
