Embodiment 1

[0023] Embodiment one: if image 3 As shown, a shock absorber spring seat spiral lift detection measuring tool includes a base 1, and the base 1 is provided with a standard seat 3 and several measuring columns 2 that can be stretched up and down. The corresponding fixed column, the measuring column 2 is connected to the base 1 through the spring 5, the base 1 is provided with a spring 5 hole 4, the spring 5 is located in the spring 5 hole 4, the elastic force of the spring 5 is greater than the weight of the spring 5 seat, the spring 5 The upper end is connected with the measuring column 2, and the lower end is connected with the spring 5 hole 4 of the base 1.

[0024] The present invention determines the height dimension of each measuring column 2 according to the relative position distance of each lift point of the 5 spring seats, that is, the surface connected by the vertices of each measuring column 2 is the helical lift surface of the 5 spring seats. During detection, th...

Embodiment 2

[0025] Embodiment two: if Figure 4 As shown, the measuring column 2 in this embodiment is composed of an external casing 21 and a telescopic column 22 inside the casing 21, the casing 21 is fixedly connected to the base 1, and the telescopic column 22 is connected to the casing 21 through a spring 5 , the elastic force of the spring 5 is greater than the weight of the spring 5 seat, the upper end of the spring 5 is connected with the measuring column 2, and its lower end is connected with the casing 21, and the lower tolerance position of the tolerance zone 6 of the side wall of the measuring column 2 is flat with the upper surface of the casing 21 together. The remaining structures and usage methods of this embodiment are the same as those in Embodiment 1. During testing, each measuring column 2 is just in contact with the spring 5 seat. It is judged as qualified, and when it is outside the tolerance zone 6 of the measuring column 2, it is judged as unqualified.

Embodiment 3

[0026] Embodiment three: as Figure 5 As shown, the difference from Embodiment 1 is that a measuring seat is added above the base 1 in this embodiment, the standard seat 3 and the measuring column 2 pass through the measuring seat, and the measuring column 2 can be moved up and down relative to the measuring seat telescopic, a backing plate 7 is provided between the measuring seat and the base 1, and they are fixed together by screws 8 passing through the base 1, the backing plate 7 and the measuring seat in sequence, and the lower tolerance position of the tolerance zone 6 of the side wall of the measuring column 2 is the same as The upper surface of the measuring base is even, and a stop step 9 is provided on the part of the measuring column 2 below the measuring base, so as to ensure that the protruding height of the measuring column 2 remains unchanged. The method of use of this embodiment is the same as that of the previous two embodiments. During detection, each measurin...

Abstract

The invention discloses a measuring tool for detecting the spiral lift of a vibration absorber spring seat, comprising a base, wherein a stand seat and a plurality of measuring columns retractable up and down are arranged on the base. The measuring tool visually judges whether the spiral lift of the spring seat is eligible according to the retractable change amount of the measuring columns and by means of a tolerance range, and has the characteristics of use convenience and measurement accuracy; therefore, the problems of not easy positioning of the spring seat and inaccurate measurement are solved; moreover, the measuring tool is capable of causing the spring seat to detect a plurality of points in the working position, and simultaneously solves the problem that the spring seat is incapable of online verification and batch verification; therefore, the measuring tool has great popularization value in the detection process of similar products.

Description

technical field [0001] The invention relates to a helical seat lift measuring tool, in particular to a shock absorber spring seat helical lift measuring tool. Background technique [0002] The spring seat product has always been a difficult point in the design process of the shock absorber, and the helical lift of the spring seat is an important factor affecting the performance of the shock absorber, such as figure 1 and figure 2 As shown, the spring seat is a part with a relatively complicated shape. Although the shape of the spring seat of each product is different, its design principle and assembly principle are the same. , point e relative to the longitudinal distance of point a) is one of its important technical indicators, whether the lift meets the technical requirements will directly affect whether the coil spring and the spring seat can fit well and be stable when the shock absorber assembly is assembled , not skewed, if the lift exceeds the standard seriously, i...
