Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] combine figure 2 , image 3 , Figure 4 as well as Figure 5 Commonly shown is a rotary encoder testing device, which includes a frame, on which a motor 7 is installed, and the motor 7 includes an output shaft 1 71 and an output shaft 2 72 arranged on coaxial lines.
[0025] The output shaft one 71 is connected with one end of the drive shaft 3 through the coupling 5, the drive shaft 3 is installed on the bearing 19, and the drive shaft 3 is sleeved with a spacer 8 to prevent the axial movement of the output shaft one 71. The other end of the drive shaft 3 is used to fixedly connect the sample encoder code disc 21 of the sample rotary encoder 2, and the other end of the drive shaft 3 is fixedly connected with the sample encoder code disc 21 of the sample rotary encoder 2, and the sample rotary encoder The code wheel 21 and the driving shaft ...

The invention discloses a rotary encoder tester. A motor is installed on a frame, a motor output shaft 1 and a motor output shaft 2 are arranged coaxially, the motor output shaft 1 is connected to oneend of a drive shaft through a coupler, the output shaft 1 directly drive the drive shaft, and the error is effectively reduced. The other end of the drive shaft is used for fixedly connecting a sample encoder code disc, and a sample encoder reading head is positioned opposite the sample encoder code disc and is fixedly connected to the frame. The positions of the sample encoder reading head andthe sample encoder code disc can be changed. A reference encoder code disc is fixedly connected to the output shaft 2, the reference encoder code disc is oppositely provided with a reference encoder reading head fixedly arranged on an inner wall of a motor cover, and the positions of the reference encoder code disc and the reference encoder reading head can be changed. The output shaft 1, the output shaft 2 and the drive shaft are all on the same axis, the test error is effectively reduced, and the tester can test the accuracy of a sample encoder as well as the accuracy of a reference encoder.
Description
technical field [0001] The invention belongs to the technical field of encoder testing equipment, and in particular relates to a rotary encoder testing device. Background technique [0002] Such as figure 1 As shown, in the prior art, the accuracy test of the rotary encoder in the industry is usually that the motor drives the sample rotary encoder 2 at a variable speed through the synchronous belt of the belt transmission transmission system 17, wherein the reference encoder 9 is installed on the motor 7, The sample encoder 2 is installed on the test shaft, and the accuracy of the sample encoder 2 can be judged by comparing the output position angles of the two encoders. Due to the elasticity of the synchronous belt and the installation gap, the stability of the test results is poor and the test accuracy is also affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotary encoder testing device, which can...
