3 common core problems with tool clamps and fixtures
Published Time:
2026-08-19
The positioning datum surface is worn, the positioning pins are loose, and debris and foreign matter accumulate in the fixture
Unstable positioning accuracy problem
The positioning datum surface is worn, the positioning pins are loose, and debris and foreign matter accumulate in the fixture, causing parts to be placed offset; the datum selection is unreasonable and the datums do not overlap, resulting in processing/inspection size fluctuations and large batch size deviations.
Part deformation caused by clamping
The layout of the clamping points is unreasonable and the clamping force is too large. Thin-walled parts and plastic shells are elastically deformed under pressure. The parts rebound after the clamp is released after processing, and the final size and flatness are out of tolerance.
Fixture versatility and service life issues
Product change requires remaking the entire set of jigs, which requires a long development cycle and high costs; the jigs lack wear-resistant treatment and will wear out quickly after long-term repeated use; they lack anti-fool structures, and employees place parts backwards and skewed, resulting in batch defects.
