Embodiment 1

[0021] Example one: such as image 3 As shown, a shock absorber spring seat spiral lift detection measuring tool, including a base 1, the base 1 is provided with a standard seat 3 and a plurality of up and down telescopic measuring columns 2, the standard seat 3 is in line with the spring seat hole Adapted fixed column, the measuring column 2 is connected to the base 1 through the spring 5, the base 1 is provided with a spring hole 4, the spring 5 is located in the spring hole 4, the elastic force of the spring 5 is greater than the weight of the spring seat, the upper end of the spring 5 and the measurement The column 2 is connected, and its lower end is connected with the spring hole 4 of the base 1.

[0022] The present invention determines the height dimension of each measuring column 2 according to the relative positional distance of each lifting point of the spring seat, that is, the surface connected by the apex of each measuring column 2 is the spiral lift surface of the s...

Embodiment 2

[0023] Embodiment two: such as Figure 4 As shown, the measuring column 2 in this embodiment is composed of an outer casing 21 and a telescopic column 22 inside the casing 21. The casing 21 is fixed 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 seat. The upper end of the spring 5 is connected to the measuring column 2, and the lower end is connected to the sleeve 21. The lower tolerance position of the tolerance zone 6 on the side wall of the measuring column 2 is flush with the upper surface of the sleeve 21 . The rest of the structure and method of use in this embodiment are the same as those in the first embodiment. When testing, make each measuring column 2 just contact the spring seat. At this time, if the upper surface of the casing 21 is within the tolerance zone 6 of the measuring column 2, it is determined If it is qualified, it is judged as unqu...

Embodiment 3

[0024] Embodiment three: such as Figure 5 As shown, the difference from the first embodiment is that this embodiment is provided with a measuring seat above the base 1, the standard seat 3 and the measuring column 2 both pass through the measuring seat, and the measuring column 2 can be 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 turn. The lower tolerance position of the tolerance zone 6 of the side wall of the measuring column 2 is consistent with The upper surface of the measuring seat is flush, and a stop step 9 is also provided on the part of the measuring column 2 below the measuring seat, so as to ensure that the extended height of the measuring column 2 remains unchanged. The method of use in this embodiment is the same as that of the previous two embodiments. During testing...

Abstract

The invention discloses a measuring instrument for detecting the spiral lift of a spring seat of a shock absorber, which comprises a base on which a standard seat and several measuring columns that can be extended and contracted up and down are arranged. The invention visually judges whether the helical lift of the spring seat is qualified or not according to the telescopic variation of the measuring column and the tolerance zone, has the characteristics of convenient use and accurate measurement, solves the problems of difficult positioning of the spring seat and inaccurate measurement, and can make The spring seat detects several points at the same time at the working position, and also solves the problem that the spring seat cannot be inspected online and in batches, and has a strong promotion value in the testing process of similar products.

Description

Technical field [0001] The invention relates to a spiral seat lift measuring tool, in particular to a shock absorber spring seat spiral lift detection measuring tool. Background technique [0002] Spring seat products have always been a difficult point in the design process of shock absorbers. Among them, the spiral lift of the spring seat is an important factor affecting the performance of the shock absorber, such as figure 1 with figure 2 As shown, the spring seat is a more complicated part. Although the shape of the spring seat of each product is different, the design principle and assembly principle are the same. Among them, the helix lift (ie point b, point c, point d) The longitudinal distance between point e and 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 firmly when the shock absorber assembly is assembled. , No skew, if the lift ...
