Description

Technical Field

[0001] The utility model relates to the technical field of hole system parts processing, in particular to a numerical control precision positioning fixture for precise hole system parts. Background Art

[0002] Hole parts refer to parts with multiple holes, which can be coaxial, parallel or perpendicular to each other. In mechanical manufacturing, the processing of hole parts is a common process. When processing hole parts, it is necessary to use positioning fixtures to position and fix the parts.

[0003] When processing parts with circular outer surfaces, existing positioning fixtures often clamp the parts through clamps with fixed sizes.

When arc clamps are used to clamp parts, the fixed arc is difficult to adapt to parts of different sizes, which causes certain inconveniences in part processing. For this reason, a CNC precision positioning fixture for precision hole parts is proposed for improvement. Utility Model Content
