AI Technical Summary
The retarder housing is prone to slight displacement during coordinate measuring machine (CMM) testing, making it difficult to complete the measurement in one orientation. This results in low measurement efficiency and large errors. Existing clamping devices are inconvenient to operate and unreliable.
A coordinate measuring and positioning fixture for retarder housing was designed, including a positioning stage, a positioning mechanism, a limiting mechanism, and a clamping mechanism. The clamping mechanism utilizes a clamping rod that is rotatably connected to the positioning stage for clamping. Combined with elastic support and limiting support, stable positioning and clamping are achieved through a press-fit ball plunger and a positioning pin.
This achieves reliable positioning and stable clamping of the retarder housing, reduces measurement errors, improves measurement efficiency and ease of operation, and meets the needs of actual operations.
