Embodiment Construction
[0037] refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , a method for making a C-shaped spring lift eccentric detection tooling of the present invention, comprising the following steps:
[0038] a) Assemble the sample spring on the suspension shock absorber to be installed, and ensure that the spring is in a natural state, and at the same time ensure that the center point of the end ring in the natural state of the spring coincides with the central axis of the piston rod of the shock absorber;
[0039] b) The spring assembled on the suspension shock absorber is scanned by a three-dimensional scanner, and the lift and eccentric data of the upper and lower coils of the spring are extracted through the reverse software, as well as the position data of the suspension shock absorber in the spring;
[0040] c) Make the upper end lift detection seat 1 and the lower end lift detection seat 2 respectively according to the lifts of the upper and lower coils of the...

The invention discloses a manufacturing and use method of a C-shaped spring lifting eccentric detection tool. The method comprises the following steps that a) a sample spring is assembled on a suspension shock absorber required to be installed, and the spring is ensured to be in the natural state; b) the spring assembled on the suspension shock absorber is scanned through a three-dimensional scanner, and the lifting and eccentric data of the upper and lower end circles of the spring and the position data of the suspension shock absorber in the spring are extracted through reverse software; c) an upper end lifting detection base and a lower end lifting detection base are respectively manufactured according to the extracted lifting of the upper and lower end circles of the spring, and an eccentric limiting detection sleeve is manufactured according to the extracted eccentric data of the spring; and d) a supporting post is installed on the lower end lifting detection base according to the position data of the suspension shock absorber in the spring, and a fixed body connected through threads sleeves the upper part of the supporting post. Spring lifting eccentric detection is facilitated by the method and the accuracy is high.
Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of spring detection, in particular to the technical field of a method for manufacturing and using a C-shaped spring lift eccentricity detection tool. [0003] 【Background technique】 [0004] In the prior art, since the outer diameters of the "C"-shaped springs are different, it is impossible to find a detection benchmark, and the verticality detection method cannot be used to detect the lift, and the eccentricity detection is also inconvenient. [0005] 【Content of invention】 [0006] The purpose of the present invention is to solve the problems in the prior art, and propose a method for making and using a C-shaped spring lift eccentricity detection tool, which can facilitate spring lift eccentricity detection and has high accuracy. [0007] In order to achieve the above object, the present invention proposes a manufacturing method of a C-shaped spring lift eccentricity detection tool, comprising th...
