AI Technical Summary

Technical Problem

Existing encoders are difficult to install on the grating mount and servo motor shaft, have low assembly efficiency, and the grating sheet is easily damaged during transportation.

Method used

The design employs a clamping assembly and a mounting assembly. The clamping assembly converts axial movement into radial clamping through the inclined block and the inclined surface transmission structure of the transmission head. The mounting assembly achieves stable connection and positioning between the grating seat and the rotating shaft through the detachable connection of the bearing seat and the limiting post.

Benefits of technology

It improves the ease and precision of installation, reduces the risk of coaxiality misalignment between the grating holder and the rotating shaft, avoids damage to the grating sheet, simplifies the assembly process, and improves installation efficiency.

Abstract

This application provides a compact absolute encoder, belonging to the field of encoder technology. It includes a mounting housing, within which a grating seat is provided. A grating sheet is mounted on the grating seat, and a circuit board is located on the upper side of the grating sheet. A connecting housing is located on the upper side of the mounting housing. It also includes: a clamping assembly disposed inside the grating seat for clamping the shaft of a servo motor; and a mounting assembly disposed at the bottom of the grating seat for limiting its position. In this application, the clamping assembly, employing a sloping block and a drive head with a sloping surface transmission structure, can convert axial movement into radial clamping action. This allows it to adapt to servo motor shafts of different diameters without requiring replacement of specialized parts, significantly enhancing versatility and reducing installation difficulty. It also effectively prevents center offset during clamping, ensuring the coaxiality of the grating seat and the shaft, improving position detection accuracy, and solving the problem of high installation difficulty in existing technologies.
