Embodiment 1
[0033] Such as figure 1 As shown, a superimposed force standard machine with a large range of the present invention includes: a main frame 1, a reverser 2, a large-range force-measuring cylinder 3, a small-range force-measuring cylinder 4, and a large-range standard sensor 5-1 , large-range standard sensor meter 5-2, small-range standard sensor 6-1, small-range standard sensor meter 6-2, tested sensor 7-1, tested sensor meter 7-2, servo control system 8, etc. Among them: the main frame 1 is composed of the main frame bottom plate 1-1, the main frame column 1-2, the main frame upper beam 1-3, the reverser 2 is composed of the reverser lower pressure plate 2-1, and the reverser pull rod 2-2 , and the upper platen 2-3 of the reverser is composed.
[0034]The large-range force-measuring cylinder 3 is installed on the main frame bottom plate 1-1, and the measured sensor 7-1 is installed on the lower pressure plate 2-1 of the reverser. -1 is separated, and the large-range force me...
Embodiment 2
[0042] figure 2 Another embodiment of the present invention is shown. In this embodiment, the large-range standard sensor 5-1 is composed of three sensors connected in parallel, and is installed on the lower platen 2-1 of the reverser 2. Its working mode Same as Example 1.
[0043]
Embodiment 3
[0045] image 3 It is an embodiment of the present invention that adopts a dual-purpose structure of tension and compression. The difference between it and Embodiment 1 is that: the main frame 1 has a main frame middle beam 1-4, and the reverser 2 has a reverser middle pressure plate 2- 4. A large-range standard sensor reverse pull rod 9 is set on the large-range standard sensor 5-1, and the small-range force-measuring cylinder 4 and the large-range force-measuring cylinder 3 respectively pass through the middle pressure plate 2-4 of the reverser and the reverser The upper platen 2-3 exerts force, but its force measurement principle is the same as figure 1 The structures shown are exactly the same, and the detection of the pulling force of the measured sensor 7-1 is realized by a large-range standard sensor reverse pull rod 9 arranged on the large-range sensor 5-1, and the large-range force sensor 5-1 Between the base plate 1-1 of the mainframe frame is a tension test space, ...
