AI Technical Summary

Problems solved by technology

However, for the detection of the frictional resistance of the ball screw, the existing detection means and methods are very limited.
The frictional resistance of the ball screw is related to whether the machining accuracy and assembly accuracy of the screw and the screw nut meet the design requirements, and whether it has been worn after a period of use, which affects the repeat positioning accuracy and service life.

Abstract

The present invention relates to a system for detecting the frictional resistance of a ball screw, comprising: a detection platform system including a detection platform configured to place a ball screw to be tested; a power system configured to for pushing out the push rod of the ball screw to a designated position; and a servo press system configured to push back the push rod of the ball screw for at least a distance, and during this time measure the back to the pressure of the push rod of the ball screw and / or the movement speed of the push rod.

Description

technical field [0001] The invention relates to a ball screw friction resistance detection system. Background technique [0002] Ball screw is not only the most commonly used transmission element in engineering machinery and precision machinery, but also used as a precise detection element. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, while featuring high precision, low frictional resistance, and high efficiency. [0003] In view of the important role of the ball screw, it is very important to test it before leaving the factory or before actual use. According to the characteristics of the ball screw and the actual application requirements, in the existing conventional detection technology, generally only the repeated positioning accuracy and the axial runout accuracy of the ball screw are detected. Although there are countless detection methods and detection tools, grating scales and dial indicators are ge...
