Encoder positioning shell with corrugated structure and manufacturing method thereof

Abstract

The invention relates to the technical field of electronic components and particularly relates to an encoder positioning shell with a corrugated structure and a manufacturing method thereof. The positioning shell is provided with a plurality of positioning projections, and a positioning groove which is matched with a positioning and rotating mechanism of the encoder is formed between any two adjacent positioning projections. In the process of matching, rotating and positioning the positioning and rotating mechanism, since the surfaces of the positioning projections are smooth arc structures, a smooth corrugated structure is formed by the positioning projections and the positioning grooves, the positioning and rotating mechanism can smoothly slide from one positioning groove to a next positioning groove without stay between the two positioning grooves, a phenomenon of forward or lagged signal output is avoided, and the signal output precision is high. The manufacturing method of the encoder positioning shell with the corrugated structure has the advantages of streamline processing, high production efficiency and the facilitation of the reduction of production cost.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an encoder positioning shell with a corrugated structure and a manufacturing method thereof. Background technique [0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. It is widely used in communication equipment. The positioning shell (positioning partition) is a positioning device that plays a role in precise positioning in the encoder. The part structure, through which it can switch gears to achieve the purpose of changing the signal output, is required to have better high temperature resistance and wear resistance, and high signal output accuracy. [0003] The existing positioning shells applied to encoders mainly include the following types: (1) Use thin metal materials to punch holes to form spaced positioning holes to achieve positioning purposes; (2) Use plas...

Problems solved by technology

However, the positioning housing that uses thin metal material punching to form spaced positioning holes is prone to the phenomenon that the positioning rotating plate stays between the two positioning holes of the positioning shell during the process of cooperating with the positioning rotating piece to rotate and locate, resulting in output signal Early or late, resulting in errors in editing codes, and even failure of the positioning function. In addition, in the process of relative rotation, the degree of wear and tear is large. With the extension of the number of positioning uses, it is easy to cause the positioning point to be relatively blurred, the rotation torque is light, and it is easy to touch when touching. The phenomenon of position movement; positioning parts made of plastic or zinc alloy materials have poor high temperature resistance, wear resistance, and short service life; using stainless steel and other materials to obtain positioning parts through injection or casting molding is not only complicated and inefficient. Mold has short service life, high cost and easy to cause environmental pollution
