Embodiment Construction

[0020] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0021] Such as figure 1 As shown, the variable spring assembly includes a top plate 1 and a bottom plate 2 facing each other and a spring body 3 vertically arranged between the top plate 1 and the bottom plate 2. There are two spring bodies 3 arranged side by side. In this embodiment, preferably, both ends of the spring body 3 are respectively fixedly connected to the top plate 1 and the bottom plate 2 by welding.

[0022] Specifically, a cylindrical body 4 is vertically provided between the two spring bodies 3 , and the lower end of the cylindrical body 4 is tightly connected to the bottom plate 2 . Preferably, the cylinder body 4 and the bottom plate 2 are sealed and fixedly connected by welding. The bottom plate 2 has...

Abstract

The invention provides a variable spring assembly, and belongs to the technical field of machines. The variable spring assembly comprises a top plate, a bottom plate and spring bodies arranged betweenthe top plate and the bottom plate. The two spring bodies are arranged, a barrel is arranged between the two spring bodies, the barrel is fixedly connected with the bottom plate, and the bottom plateis provided with air outlet holes. The air outlet holes communicate with the barrel. A guide bucket is arranged in the barrel, the top and the bottom of the guide bucket are closed and opened correspondingly, the guide bucket is fixedly connected with the upper plate, and seal is formed between the guide bucket and the barrel. An electromagnet is arranged in the guide bucket and comprises a shelland a main shaft. The shell stretches out of the guide bucket, seal is formed between the shell and the guide bucket, the lower end of the shell is fixedly connected with the barrel through a support, a plate body is further horizontally arranged in the barrel and fixedly connected with the lower end of the main shaft, and the electromagnet can drive the plate body to abut against the lower plateand close the air outlet holes. An air inlet hole is formed in the barrel wall of the barrel in a penetration manner and located between the plate body and the guide bucket, and an air nozzle communicating with the air inlet hole is fixed to the exterior of the barrel. The variable spring assembly is high in buffering precision.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a spring, in particular to a variable spring assembly. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. [0003] Existing springs such as a compression spring disclosed in the Chinese Patent Library [Application No.: 201620912062.4] include a spring body, the two ends of the spring body are provided with end face fixing panels, the spring body is a pair of cylindrical hollow spiral bodies, and the fixing panels are with fixed The round pancake panel of the buckle of the two helical bodies of the spring body, the buckle is arranged on the outside of the spring body along the direction parallel to the central axis of the spring body. [0004] The above-mentioned compression spring realizes t...
