AI Technical Summary

Technical Problem

Existing elasticity testing devices have difficulty in stably clamping springs with different inner diameters and wire diameters, resulting in large fluctuations in test data. Furthermore, they cannot simulate the instantaneous impact loads in actual use scenarios, leading to significant deviations between test results and actual performance.

Method used

The system employs a cylinder-driven V-shaped clamping frame for adaptive clamping, combined with a motor-driven lead screw and gear system to achieve precise loading, simulate instantaneous impact loads, and obtain accurate elastic force values ​​by displaying deformation through a scale bar.

Benefits of technology

It achieves stable clamping of springs with different inner diameters, improves test accuracy, and makes test results closer to actual working conditions, overcoming the problems of unstable fixation and single loading method of traditional devices.

Abstract

This utility model discloses an elastic force testing device for processing shock-absorbing springs, relating to the field of shock-absorbing spring elastic force testing technology. It includes a housing and a spring body. A scale strip is provided on the inner rear end of the housing. A first motor is fixedly installed on the upper end of the housing. A lead screw is fixedly connected to the output end of the first motor. A lifting plate is threaded to the outer side of the lead screw. A gravity block is provided below the lifting plate. Two pointers are fixedly connected to the rear end of the gravity block. The elastic force testing device for processing shock-absorbing springs described in this utility model uses a cylinder to drive the lifting plate upwards. Through the linkage between the rotating seat and the pull rod, a V-shaped clamp can adaptively clamp springs of different inner diameters. Furthermore, the anti-slip texture on the outer side of the V-shaped clamp significantly enhances friction, effectively solving the problem of test data fluctuations caused by unstable fixing in traditional devices, and greatly improving test accuracy.
