Abstract

The present invention discloses an adjustable helical spring regulation method for correcting spring helical pitch tolerance and fatigue deformation and regulation device. Said regulation device is fixed on one end of shell body of adjustable helical spring, and can be used for changing pretension or prestress of helical spring to correct spring helical pitch tolerance and fatigue deformation and make the spring helical pitch be restored to the helical pitch of rotation body. The invented regulation method can be used in various adjustable helical springs.

Description

technical field [0001] The invention relates to an adjustment method and an adjustment device of an adjustable coil spring for correcting spring pitch tolerance and fatigue deformation, in particular to an adjustment of spring pitch tolerance and fatigue deformation of an adjustable coil spring that can be applied to a shock absorber method. Background technique [0002] The spring coefficient of conventional coil springs is determined at the time of production. Therefore, when used in machinery and equipment, there are often problems with different specifications. Therefore, in order to match different machinery and equipment or for different purposes, it is necessary to design different coil springs for backup. , is not in line with economic benefits. [0003] In view of this, the inventor of this case aimed at the above-mentioned problems, and published the No. 1368609 patent "Adjustable Helical Spring Housing Device" on September 11, 2002 in Mainland China, which propos...
