Description

Technical Field

[0001] The utility model relates to the field of ball screw detection, in particular to a strength detection device. Background Art

[0002] A ball screw is a mechanical component that converts rotational motion into linear motion and is widely used in various mechanical devices and precision instruments. It consists of a screw, a nut, and balls, with motion conversion achieved through the rolling motion of the balls between the screw and nut. The ball screw operates based on the rolling motion of the balls between the screw and nut. As the screw rotates, the balls roll in the thread grooves, pushing the nut axially. This motion conversion is highly efficient and precise.

[0003] Ball screws must be tested on prototypes during production to ensure their performance and accuracy. Existing ball screws do not have good screw positioning during strength testing, which can cause the screw to shift or wobble during testing. This results in inaccurate test data and an inability to truly reflect the actual strength of the ball screw. Furthermore, during high-strength testing, if the screw is not secured, it may move or fall off suddenly, causing damage to the equipment or personal injury. Furthermore, if the ball screw is not secured, accurate stress analysis is difficult to perform, making it impossible to effectively evaluate its performance under different load conditions.

[0004] Therefore, it is necessary to provide a new strength detection device to solve the above technical problems. Utility Model Content
