Embodiment Construction

[0022] The embodiment of spring device among the present invention: as Figure 1 to Figure 5 As shown, the spring device is mainly composed of a spring body 4 and a press-fit assembly, wherein the spring body 4 is a cylindrical coil spring, and the press-fit assembly is composed of a positioning member, a stopper and a spring pressing plate 1 . The positioning part is a spring rod 3 coaxially installed in the inner hole of the spring body 4, and the spring rod 3 is provided with a row of positioning pin holes 5 arranged at intervals along the axial direction. The radially extending perforation, and the positioning pin hole 5 is formed on the spring rod 3 for the stopper to move axially along the positioning member, and after the stopper moves in place, the limiter is axially limited and assembled in the positioning position. The adjustment structure on the component. The positioning part is the fixed pin shaft 2 that is installed in the positioning pin hole 5 along the radial...

Abstract

The invention discloses a spring press fitting component and a spring device using the same. A positioning element of the press fitting component is inserted and assembled on a spring body in a sleeving manner in the axial direction, a blocking element is blocked at the end part of the spring body, and a regulating structure is arranged on the positioning element. While in use, along with continuous energy storage and energy release of the spring device, the spring device continuously extends and contracts, so that when a flabby situation appears in the spring body in a device body of the spring device, that is when a loose sign appears between the spring body and the blocking element, the blocking element can axially moves along the positioning element, the blocking element which is regulated in place is fastened on the positioning element once again, the spring body in the spring device is pre-fastened once again; therefore, under the condition that the fatigue damage of the spring body appears, the flabby situation of the spring body can be compensated in a proper time by regulating the pre-fastening degree of the spring device, and the situation that the spring body and the blocking element are loose is avoided.

Description

technical field [0001] The invention relates to a spring pressing assembly and a spring device using the pressing device. Background technique [0002] As an important basic part of mechanical equipment, springs are used in many fields of modern industry, especially in high-voltage switches in the power industry, and the demand for cylindrical coil spring devices is also increasing. At present, cylindrical coil springs are often used as energy storage components in the operating mechanism of high-voltage switches. For example, an energy storage spring is connected between the drive cam and the frame. The energy storage spring will make the manual or electric The torque acting on the energy storage cam is converted into elastic potential energy and stored in the energy storage spring as a reserve power source in the closing stage, and this operation is performed before each closing to realize the normal operation of the spring operating mechanism. run. However, during the e...
