Technical Field

The utility model belongs to the technical field of mechanical spring detects, especially, relate to a small-size adjustable spring elastic stiffness detection device.

Background

In the field of spring manufacturing, in order to ensure the performance of the spring, a plurality of items of tests are required to be carried out on the spring, wherein the tests comprise the test of elastic stiffness. At present, the existing spring elastic stiffness experimental device mainly adopts a fixed plate to fix one end of a spring, measures a tension value and a deformation quantity after pulling or compressing the spring, and then calculates the spring elastic stiffness according to Hooke's law. However, most of the existing spring stiffness detection devices are complex in structure, large in size, difficult to read, and only capable of detecting springs with fixed lengths, so that a small and adjustable spring stiffness detection device is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a small-size adjustable spring elastic stiffness detection device aims at solving current spring elastic stiffness detection device structure complicacy, and the size is big, and the reading difficulty can only detect the problem of the spring of regular length.

The utility model discloses a realize like this, including the detection device shell, first lifting hook, the second lifting hook, the reading pointer, the sliding block, the third lifting hook, spacing auricle, holding screw, the spout, scale mark and round hole, the scale mark sets up on the detection device shell surface, the sliding block is adorned in the spout, be equipped with first lifting hook on the detection device shell, the reading pointer is equipped with to the sliding block top, the second lifting hook is equipped with to the sliding block front side, the sliding block rear side is equipped with the third lifting hook, the second lifting hook is the same with the structure of first lifting hook with the structure of third lifting hook, spacing auricle is equipped with at the sliding block both ends, be provided with the round hole on the detection device shell.

Furthermore, the material used for the detection device shell is aluminum alloy.

Furthermore, the first lifting hook is connected with the shell of the detection device in a threaded connection mode.

Furthermore, the limiting lug is connected with the sliding block through a set screw.

Furthermore, the second lifting hook and the third lifting hook and the reading pointer are connected with the sliding block in a threaded mode.

Furthermore, the front end of the reading pointer is pointed.

The utility model has the advantages that: this spring elastic stiffness detection device, because the sliding block can freely slide in detection device shell spout, consequently, the spring of the different length of detectable, in addition, detection device shell top has been beaten the round hole, conveniently carries and hang. The first lifting hook, the second lifting hook, the third lifting hook, the reading pointer and the limiting lug are all detachable, and maintenance and replacement are convenient.
