The invention discloses a disk spring device adjustable in force value characteristic. The disk spring device comprises a bottom supporting piece, a disk spring, spiral flat plates, an upper pressing part, at least three contact probes, a plurality of connecting rods and a pin key, wherein the bottom supporting piece is fixed; the disk spring is arranged on a bottom supporting piece shaft in a sleeving manner and placed in an annular groove with the concave surface facing downwards; the central axles of the bottom supporting piece, the disk spring and the upper pressing part coincide with each other; the cylindrical central hole of the upper pressing part is connected with the bottom supporting piece shaft in a matched manner through a pin structure; the upper pressing part can perform up-down movement along the bottom supporting piece shaft without rotating. According to the disk spring device adjustable in force value characteristic, when the upper pressing part is compressed, the pressure force is transmitted to the convex surface of the disk spring through the contact probes; when the lower spiral flat plate and the upper spiral flat plate are rotated in a linkage manner, the contact probes can perform equidistance movement along respective radial slots in the upper pressing part, so that the contact points of the contact probes and the disk spring can perform equidistance movement on the convex surface of the disk spring in the radial direction; the force value characteristic of the disk spring is changed along with different contact positions of the contact probes on the convex surface of the disk spring in the radial direction.
Description
technical field [0001] The invention relates to a disc spring device, in particular to a disc spring device with adjustable force characteristic. Background technique [0002] In the prior art, a disc spring can only output one type of force value characteristics, and in structures requiring different force value characteristics, it is generally adjusted through external force value conversion mechanisms such as levers or gears. The external transformation mechanism will occupy a large space; due to factors such as friction, the external transformation mechanism has force loss; the external transformation mechanism is complicated and the manufacturing cost is high. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a disk spring device with adjustable force value characteristics, and realize the output of disk springs with different force value characteristics through the linkage rotation of the low...
