Abstract

PROBLEM TO BE SOLVED: To obtain a high-accuracy, large-capacity, compact and low-cost load detection apparatus which can hold for a long time by setting a screwing ring to a main body supporting one end of an elastic body (coned disc spring). SOLUTION: This apparatus has a structure in which an eye bolt 2 is combined via an elastic body (coned disc spring) 5 to a main body 1 having a fork end 7. A ring 3 is set to be screwed to the main body 1 supporting one end of the elastic body 5. The elastic body 5 bends by a load, thereby moving the eye bolt 2 left. The ring 3 screwed to the main body 1 supporting one end of the elastic body 5 is rotated to make an end face 3a touch an end face 2a of the eye bolt 2. A value of the load is measured from an index and a load scale. Since the coned disc spring is used as the elastic body 5, a large load is obtained with a slight amount of the bend, making the apparatus compact in structure. The load detection apparatus which has a good cost performance, is highly accurate, improves disadvantages of a hydraulic type and can hold for a long time is thus obtained.

For example, a 6TON disc spring has an outer diameter of 50 m.
m and a thickness of 6.5 mm are compact, but there is a drawback that it is difficult to measure visually because the amount of deflection is as small as 0.8 mm for two series plates. Then, the end face of the ring screwed to the main body is brought into contact with the end face of the eyebolt supporting the other end of the elastic body (disc spring), and the load is read by a pre-calibrated load scale on the ring and an index on the main body. This disadvantage is thereby eliminated.
