Problems solved by technology

[0003] The height-to-diameter ratio of the spring, that is, the ratio of height to middle diameter, is an important parameter for the stability of the spring. Generally speaking, if the height-to-diameter ratio is greater than 5.3, especially 10 or more, its stability is very poor and its self-supporting performance is not good. Therefore, measuring its Elasticity is a big problem
Slender springs with extremely large height-to-diameter ratios cannot be measured by traditional force measurement methods

Embodiment

[0020] The applicable elongated spring of the elongated spring force measuring device of the present invention is as image 3 As shown, the device consists of figure 1 , figure 2 As shown, it mainly includes a fixed part and a movable part; the movable part is the ball push rod 5, and the fixed part includes a dynamometer 1, a workbench 2, a guide rod 3, and a support plate 4; A support plate 4 is fixed on the workbench 1, similar to a bridge pier; four guide rods 3 penetrate into the support plate 4 in parallel, similar to a bridge; the ball push rod 5 pushes the slender spring 6 into the gap between the four guide rods 3 And push it to the direction of the dynamometer 1; one end of the dynamometer 1 is against the vertical plate of the workbench 2, and the other end is close to a support plate 4, so that the thrust of the slender spring 6 acts on the dynamometer 1 .

[0021] The more the number of supporting plates 4 is, the greater the stabilizing effect is, and the mor...

Abstract

The invention discloses a spindle spring force measuring device which comprises a workbench (2), a force measuring meter (1), a supporting plate (4), a plurality of guide rods (3) parallelly penetrating the supporting plate (4), and a pushing rod (5) pushing a spindle spring (6) into intervals of the guide rods (3) and pushing the spindle spring towards the force measuring meter (1). The force measuring meter and the supporting plate are fixed on the workbench. The spindle spring force measuring device has the advantages of simple structure, accuracy in force measuring and convenience for operation.

Description

technical field [0001] The invention relates to the field of spring inspection, in particular to a device for measuring the elastic force of a slender spring with a super large aspect ratio. Background technique [0002] As a commonly used elastic element, spring is widely used in various devices. Springs are used in most mechanical devices, especially cylindrical springs are widely used. The traditional cylindrical spring force measuring device is to let the spring stand on the pallet, and a pressure plate on the upper part is pressed down, so that the spring height is compressed to a certain value, and the elastic value is measured. In order to maintain the linear relationship of spring force, it is usually necessary to measure the spring force at two or three points. [0003] The height-to-diameter ratio of the spring, that is, the ratio of height to middle diameter, is an important parameter for the stability of the spring. Generally speaking, if the height-to-diameter ...
