AI Technical Summary
Existing inside micrometers require adjustment of the tube length when measuring the inner diameter of the thrust head, which makes measurement inconvenient.
A tool for measuring the inner diameter of a thrust head heated in situ using a hot-shrink method was designed. The tool consists of a tube body, a first clamp, a second clamp, a collar, a connecting ring, a connecting tube, a knob cover, and a bidirectional screw. The knob cover drives the bidirectional screw to rotate, the collar moves the clamps away from or closer to it, the clamps move the connecting block, and the clamp plate abuts against the inner diameter to fix the clamps and prevent the tube length from being adjusted.
This eliminates the need to adjust the tube length, making the measurement process more convenient and improving reading accuracy.
