Description

Technical Field

[0001] The utility model relates to the technical field of test for collecting rotation angle measurement data, and particularly relates to a test tool for collecting rotation angle measurement data. Background Art

[0002] An encoder is a high-precision sensor for measuring rotation angles. The encoder is used for collecting output data of rotation angles, analyzing data, and measuring the precision of similar rotation angle sensors, with a resolution of up to 0.022°. However, in the current technology, when measuring the rotation angle data of a motor through an encoder, the installation method of the encoder needs to be improved. For example, the encoder is installed on a bracket through bolts and then installed with a rotating angle motor by using a coupling. Since there are pores between the bolts and the screw holes, the installation stability of the encoder is poor, and the measured rotation angle data has errors. Secondly, the installation space between the encoder and the rotating angle motor is limited, it is difficult to install with bolts, and the assembly method of replacing and disassembling the encoder has a long time limit, which is not conducive to the efficient progress of the test work.

[0003] For example, the publication (announcement) number: CN203688220 discloses a reducer test device, which includes a support platform and a servo motor, an input end rotary encoder, and an output end angle encoder arranged on the support platform. The servo motor provides power for the reducer to be tested. The input end rotary encoder is connected to the input end of the reducer to be tested, and the output end of the reducer to be tested is connected to the output end angle encoder. The precision of the output end angle encoder is ±1 arc second, and the precision of the input end rotary encoder is not greater than ±n arc seconds, where n is the minimum reduction ratio of the reducer to be tested.
