Description

Technical Field

[0001] This application belongs to the field of reliability testing of sights, and specifically relates to a reliability testing device for a sight handwheel adjustment mechanism. Background Technology

[0002] Sights are primarily auxiliary devices used to enhance the observation and aiming capabilities of light weapons, significantly increasing the combat effectiveness of personnel. However, they also face diverse usage requirements in various environments. To meet these diverse needs, the reliability test results during the sight's development phase become crucial criteria for determining product qualification, and these reliability tests provide strong assurance for actual combat use. In reliability testing, the adjustment handwheel is a key component due to its high frequency of use, undergoing thousands of operational tests in high and low temperature environments, typically representing a significant portion of the testing time and manpower / resources.

[0003] Reliability testing of sights is an indispensable part of military product testing, and it is of great significance for ensuring the product can still function normally in various harsh environments. The handwheel mechanism adjusts the sight's diopter and focal length. In actual use, the handwheel is used very frequently and needs to withstand various environmental requirements, making reliability testing of the handwheel mechanism essential. Sight handwheel reliability testing mainly involves repeatedly rotating the handwheel thousands of times under high temperature, low temperature, and normal temperature environments to verify its performance, while also testing parameters such as its starting force. Currently, reliability testing mainly relies on manual real-time operation; however, in high and low temperature environments, personnel need to be kept warm before entering environments ranging from above 70 degrees Celsius to below -20 degrees Celsius to perform the operation. Thousands of operations are time-consuming and place extremely high demands on the operator. Therefore, there is an urgent need to develop a reliability testing device for sight handwheel adjustment mechanisms to solve the above-mentioned technical problems.
