Detection clamp and detection method special for action acceleration of overload switch

Abstract

A detection clamp special for action acceleration of an overload switch comprises a base, a push rod, a top rod, a spring, a fixing cover and a hand shank. The base is provided with a positioning step on which the acceleration overload switch is installed, a threaded installation hole is formed on one side of the base, and the spring is placed on the top rod in a sleeved mode. After abutted, the fixing cover and the hand shank extend into a threaded hole on one side of the base and are fixed, and the push rod is fixedly connected to a corresponding position of a spring tensile and compression testing machine. By means of the special detection clamp and a detection method in which a resistance force magnitude received at a moment when a sensitive mechanism of the overload switch is locked is converted into an action acceleration value, a tradition detection method that acceleration magnitude measured by applying of a shock testing machine is replaced, the detection clamp and the detection method are simple, fast, convenient, low in cost and capable of achieving high-efficient and practical detection effects.

Description

technical field [0001] The invention relates to a special detection fixture and detection method for detection of acceleration overload switch action acceleration, which belongs to the field of switch control elements and is suitable for detection of the action acceleration of an overload switch with large impact acceleration. Background technique [0002] With the rapid development of modern model systems, higher requirements are placed on the anti-shock acceleration index of the acceleration overload switch, making it difficult for the traditional motion acceleration detection method to meet the requirements of the new model detection and mass production progress. It has become an inevitable development trend to explore efficient and practical motion acceleration detection methods to replace traditional detection methods. The traditional acceleration detection method is generally carried out by using a drop impact test bench, and the acceleration overload sensitive directi...

AI Technical Summary

Problems solved by technology

The disadvantage of this detection method is: when the acceleration range of the overload switch is small, the traditional detection method can meet the detection requirements, but when the range of the acceleration value reaches hundreds to thousands of g, it is difficult to use the traditional drop impact test bench for detection. helpless

Although the airbag pressurized impact table can meet the detection requirements, the cost is too high and the detection efficiency is low, which cannot meet the mass production requirements of modern models
