一九七三年,第一汽车厂铸造分厂在设计一条多触头高压造型自动线时,在主机选用了柱塞式气垫微震装置,当时为了探索这种微震机构的工作特性,和机器相同的尺寸加工制造了一个气垫微震装置。为了进一步开展对微震机构参数的试验研究,在原有试验装置的基础上,作了一些改造,并按装了自动控制线路。改装后的试验装置如图1所示。它由机座1、工作台2、司气阀滑套7、小弹簧8、司 In 1973, the first automobile factory foundry branch in the design of a multi-contact high-pressure modeling automatic line, the host selected plunger air cushion microseismic device, was to explore the microseismic institutions operating characteristics, and the same machine An air cushion microseismic device is manufactured by the size processing. In order to further carry out experimental research on parameters of microseismic institutions, some modifications have been made on the basis of the original test equipment and automatic control circuits have been installed. The modified test device shown in Figure 1. It consists of a base 1, table 2, Secretary valve sleeve 7, a small spring 8, Secretary
