Description

TECHNICAL FIELD

[0001] The utility model relates to encoder finishing technical field, especially in an adaptive hand encoder zero correction structure. BACKGROUND

[0002] Encoder is the necessary component of servo control system, needs to correspond with the zero of encoder and motor when assembling, and the usual zero adjustment method is: first, encoder and servo motor are adjusted to zero state at the same time, then the main shafts of the two are connected, and finally locked and fixed, but in the connecting process, the main shaft of encoder is easy to rotate, so that the encoder is no longer in the zero state, but it is very difficult to rotate the main shaft of encoder to make the encoder again in the zero state after the connection is completed.

[0003] At present, the adjustment mode is limited by the size of the encoder, and more axial space can be reserved for the large-size encoder to use pliers and other tools to clamp the encoder shaft to rotate, but for small-size encoder, it is not possible to reserve enough axial space, so it is not possible to use pliers to clamp the main shaft, in this case, the encoder and the motor must be separated and then the encoder main shaft is rotated to adjust the zero position, which is very inconvenient.

[0005] In view of the above problems, the existing patent provides a solution, but the buffering effect is not good, and in the working process of the encoder, inertia impact will be generated when the detected equipment starts and stops, and due to the poor buffering effect, the impact force may be directly transmitted to the internal structure of the encoder, resulting in that the zero parts of the encoder are subjected to a large stress, which affects the precision and service life of the encoder, and reduces the practicability of the device.

[0006] Therefore, an adaptive hand encoder zero correction structure is proposed. UTILITY MODEL CONTENTS
