用如下简单而廉价的结构措施来达到全自动工作的最佳功能:可回转上平台5通过侧边铰键4与下平台3相结合,下平台3在导向机构1、2的导向下可作垂直移动。射砂板6靠夹紧爪7可固定在上平台5上。两个平台3、5用双夹紧爪8夹紧在一起,这时上平台5通过弹性挡块9平放在下平台3上。与下平台相连接的双夹紧爪8在第一位置上同上平台的挡块10相啮合;在第二位置上同安装在支架11上的第二挡块12相啮合。两个平台3、5由单独一个液压缸13、14驱动,当两个平台结合成一体时,液压缸使它们一起作上、下移;当两个平台脱
The best features of fully automatic operation are achieved with simple and inexpensive structural measures as follows: the swivelable upper platform 5 is combined with the lower platform 3 by means of a side hinge 4 and the lower platform 3 is operable under the guidance of the guide mechanisms 1, 2 Move vertically. Shooting sand plate 6 by clamping jaw 7 can be fixed on the platform 5. The two platforms 3 and 5 are clamped together by the double clamping jaws 8, and the upper platform 5 is horizontally placed on the lower platform 3 by the elastic stopper 9. The double clamping jaw 8 connected to the lower platform engages the stop 10 of the upper platform in the first position and the second stop 12 mounted on the support 11 in the second position. The two platforms 3, 5 are driven by a single hydraulic cylinder 13, 14. When the two platforms are integrated, the hydraulic cylinders make them move up and down together. When the two platforms are detached
