Vertical multiple-degrees-of-freedom high-precision detector for detecting comprehensive performance of precision reducers

Abstract

The invention discloses a vertical multiple-degrees-of-freedom high-precision detector for detecting the comprehensive performance of precision reducers. The detector comprises a high-speed end torque closed module, an attitude adjustment module, and a low-speed end torque closed module. The low-speed end torque closed module includes a vertically arranged low-speed end torque closed cylinder. A loading motor, a force-increasing reducer, a low-speed end torque sensor, a low-speed end circular grating and a reducer output shaft interface are arranged in sequence from bottom to top inside the low-speed end torque closed cylinder. The high-speed end torque closed module includes a vertically arranged high-speed end torque closed cylinder. A high-speed end torque sensor, a high-speed end circular grating and a reducer input shaft interface are arranged in sequence from top to bottom inside the high-speed end torque closed cylinder. The shell of a driving motor and the shell of a detected reducer are connected together by the high-speed end torque closed cylinder. The shell of the loading motor and the shell of the detected reducer are connected together by the low-speed end torque closed cylinder. The detector is less affected by external factors, and is of high measurement precision.

Description

technical field [0001] The invention relates to a comprehensive performance detection device of a precision reducer, in particular to a vertical multi-degree-of-freedom high-precision detection instrument for the comprehensive performance of a precision reducer. Background technique [0002] Precision reducers are widely used in various fields of the national economy and national defense industry. With the development of industrial automation technology, the requirements for the performance indicators of the reducer are getting higher and higher, especially in the field of robots. The transmission efficiency and speed requirements of the reducer And the load capacity seriously affects the working accuracy and service life of the system, so the detection of the reducer becomes particularly important. [0003] With the development of the robot industry and the gradual localization of the reducer, the requirements and demands for the testing equipment of the reducer are also ge...

Problems solved by technology

[0004] With the improvement of use requirements, the structural form of the reducer has also become various. The common structure is that the input shaft and the output shaft are arranged coaxially. In some cases, the input shaft and the output shaft of the reducer are required to be parallel instead of coaxial. Or arranged at an angle. Most of the existing detection equipment for the reducer is aimed at the reducer arranged on the same axis. The structural form of the different axis cannot be detected or it needs to pay a lot of money to complete.
