Problems solved by technology

However, during the test, when the spring deforms elastically in the axial direction, the spring tends to deform in the transverse direction
If the spring changes laterally, it will affect the elastic properties of the spring and thus affect the test results

Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

A spring testing device includes a base, a fixed cover and a fastener. The base includes a base body provided with a first limiting groove; and a plurality of fixing columns arranged at intervals on the base body. A plurality of spring positioning columns arranged in the first limiting groove and fixedly connected with the bottom of the first limiting groove, the spring is sleeved on the spring positioning column, one end of the spring is accommodated in the first limiting groove, and the spring The positioning column is arranged between the two fixing columns. The fixed cover is arranged on the base, and the free ends of the fixed post and the spring positioning post pass through the fixed cover. The fastener is fixedly connected to the free end of the fixing post, and the fastener abuts against the side of the fixed cover away from the base body, and the fastener limits the fixed cover. The spring positioning post can prevent the spring from being deformed laterally. The first limiting groove can limit the spring to prevent the spring from being displaced during extrusion. Therefore, the above-mentioned spring testing device can ensure uniform elastic deformation of the spring.

Description

technical field [0001] The invention relates to a stress testing device, in particular to a spring testing device. Background technique [0002] A spring is a mechanical part that uses elasticity to work. The spring stores elastic potential energy and realizes the mutual transformation between elastic potential energy and kinetic energy. Springs can be used to control the movement of parts, alleviate shocks or vibrations, store energy, measure force, etc. Because of its low cost, simple structure and good use effect, it is widely used in machines and instruments. Moreover, springs play a very important role in various products, so whether the spring is still elastic after being subjected to long-term pressure is an important indicator to measure the performance of the spring, and it is also a strong guarantee for product reliability. [0003] Most of the devices for testing springs currently use one end of the spring to be fixed on the base, and the other end of the sprin...
