Description

Technical Field

[0001] This utility model relates to the field of metal ring processing technology, and in particular to a positioning fixture for processing metal ring workpieces. Background Technology

[0002] Ring gauges, also known as calibration ring gauges, are circular rings with specific dimensions and properties used to correct deficiencies in measuring tools. They can be divided into smooth ring gauges and threaded ring gauges. Manual grinding of ring gauges is a traditional precision repair method, suitable for scenarios where there is no professional grinding equipment or where local corrections are required.

[0003] Existing metal ring workpiece machining and positioning fixtures have relatively simple structures, diverse ring gauge specifications and sizes, difficulty in fixing, low ring gauge clamping stability, and are prone to shaking and displacement during grinding, resulting in deviations that affect grinding accuracy. They rely on experience, and grinding is time-consuming and inefficient.

[0004] Therefore, to address the problems of low stability of the ring gauge clamping in the existing metal ring workpiece machining positioning fixture, which affects grinding accuracy and grinding efficiency, a new metal ring workpiece machining positioning fixture can be designed.
