A spring axial deviation correction device

Abstract

The invention relates to an axial deviation correction device for springs. The axial deviation correction device is used for processing a spring structure. The spring structure comprises a spring bodyand a lower positioning sheet and an upper positioning sheet which are arranged on two ends of the spring body; whether the axial stress of the spring is balanced or not is judged in a detection mode; the affection position of corresponding existing error by judging the moving trajectory of a detection feedback pin; by heating the affection position, hardness is lowered in a temperature rising process; then the deformation quantity of the part of the spring under driving of an axial adjusting component is different from the deformation quantities of other positions; and the shape of a solid state changes through cooling of metal, so that the spring body tends to be vertical under the effect of elasticity.

Description

technical field [0001] The present invention relates to spring correcting equipment, more specifically, relates to a spring axial 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 all...

Problems solved by technology

[0004] At present, there is a problem with the spring with a large volume. Because of its high production cost, its reliability depends on the material and has a great influence on the structure of the spring. Generally speaking, there are the following problems: the spring is subjected to forward extrusion. In addition to generating axial force during compression, a radial component is also generated, which is called circumferential error at this time, and this component represents the bending of the spring during extrusion (generally invisible to the naked eye), and this bending is in When used repeatedly, other forces will be generated on the stressed parts
