A spring circumferential direction correcting device

Abstract

The invention relates to a circumferential deviation rectifying device for a spring. The circumferential deviation rectifying device for the spring is used for machining a spring structure. The springstructure comprises a spring body and a lower positioning sheet and an upper positioning sheet which are arranged at the two ends of the spring body. Whether the circumferential stress of the springis balanced or not is judged through a detection mode; the corresponding influence position with errors can be acquired by judging the movement track of a detection feedback needle; the influence position is heated, the hardness is reduced in the temperature rising process, and the deformation amount of the position of the spring under driving of an axial adjusting part is different from that of other positions; and the solid state can generate shape changes when metal cooling is conducted, and then the acting force of a spring body tends to be perpendicular.

Description

technical field [0001] The invention relates to a spring correcting device, more specifically, to a spring circumferential deviation correcting device. 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. Also known as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] After the modern industry occurs, novel springs such as gas springs, rubber springs, scroll springs, die springs, stainless steel springs, air springs, memory alloy springs have also been there except disc springs. The spring detection needs attention: 1. The support ring can choose cold and hot methods according to the product requirements. It is not allowed to...

Problems solved by technology

[0004] At present, there is a problem with springs with larger volumes. Due to their high production costs, their reliability depends on materials and has a greater impact on the structure of the springs. Generally speaking, there are the following problems: each spring in the same spring The elastic force of the ring is not equal, which is called the circumferential error at this time. This error will cause the metal elastic fatigue to occur more easily in the unit position, and affect the life of the spring.
