A ball screw pair axial loading device

Abstract

The invention discloses a ball screw pair axial loading device, which comprises an axial loading test bench and a ball screw pair test bench, wherein the ball screw pair test bench comprises a test bench body, a ball screw pair arranged on the test bench body and a simulation working table driven by the ball screw pair; the axial loading test bench is connected with the simulation working table; the axial loading test bench comprises a loading table body, a rolling body arranged on the loading table body and a loading rope wound on the rolling body; the other end of the loading rope is connected onto the simulation working table; and the loading table body is also provided with a loading force adjustment device acting on the rolling body for controlling the size of the loading force loaded by the loading rope on the simulation working table. Vertical direction inertia load and dynamic axial load can be applied to ball screw pairs of different models, and the device has the advantages that the structure is simple, the operation is convenient, real-time performance of motion and test response is good, and certain reliability is provided.

Description

technical field [0001] The invention belongs to the field of testing systems for control methods of high-speed precision transmission pairs, and in particular relates to a device for axially loading a ball screw pair. Background technique [0002] After entering the 21st century, according to the development trend of the new industrialization road, CNC machine tools and various mechatronic equipment are developing in the direction of high precision, high speed, intelligence, and green environmental protection. The rapid development of important industries such as aviation, automobiles, railways, and construction is inseparable from the development of high-speed, high-precision CNC machine tools, which include high-speed precision ball screws and rolling guides necessary for high-speed, heavy-duty processing machine tools and other functional components. As the execution unit of the CNC machine tool drive system, it plays a vital role in ensuring and improving the machining ...

AI Technical Summary

Problems solved by technology

Testing and manufacturing are two key parts that are inseparable and complementary. Without testing, it is impossible to verify the quality of products.

[0003] At present, the performance testing of the ball screw pair is mainly carried out under no-load or light-load conditions. Even if there is an axial loading device, the hydraulic loading device with high cost and complex control methods is mostly used.
