Ball screw performance test bench based on motor servo loading

Abstract

The invention relates to a ball screw performance testing testbed based on motor servo loading. Rolling guide rails are arranged on a bed body, a movable pair is formed by the rolling guide rails and guide rail sliding blocks, the guide rail sliding blocks are fixedly connected with a workbench, a load ball screw pair is arranged in a middle groove in the bed body, a load nut seat is fixedly connected with the workbench, linear motor permanent magnet guide rails are arranged in outer inner grooves symmetrically formed in the bed body, a movable pair is formed by the linear motor permanent magnet guide rails and linear motor sliding blocks, and the linear motor sliding blocks are fixedly connected with the workbench. The ball screw performance testing testbed can simulate static or dynamic loads through a rotary servo motor or a linear servo motor, meanwhile, the locating precision, repeated locating precision, reverse errors, temperature rise and friction torque of the load ball screw pair are examined, the feasibility of the ball screw performance testing testbed in practical work is verified, the testbed has the advantages of being flexible in loading mode, high in loading precision and stable in loading process, and load lead screws of different lengths and the identical specification can be used for tests on the same performance testbed.

Description

Technical field [0001] The invention relates to a ball screw pair performance test device, in particular to a ball screw performance test bench based on motor servo loading. Background technique [0002] Ball screw is one of the most commonly used transmission components in precision machinery. It is a screw transmission component composed of screw (screw), nut and ball. Its main function is to convert rotary motion into linear motion with high precision and reversibility. The characteristics of high performance and high efficiency directly determine and affect the performance of the CNC machine tool. Therefore, necessary performance tests on the ball screw are beneficial to early detection of problems, reducing the rate of defective products, and reducing unnecessary Downtime, improve the quality of machine tools. However, as the role of test technology and conditions in the process of modern scientific research and product production is becoming more and more important, people...
