Reconstruction of inner diameter gauge when using post-column boring on a trampoline
On a T612 trampoline, a cylindrical part with a length of 1000 mm and an internal diameter of φ298.8_0~(+0.10) mm was cut. The process method is that the workpiece does not move, the mast rotates, the boring tool is clamped on the mast, and the workpiece is moved to realize the feeding. Since the mast passes through the center of the cylinder and is supported on the rear pillar, the internal caliper has been used to measure the inner diameter size during boring. This measurement method is large and inaccurate. The processor is required to have good technology and rich experience in measurement. In 2001, we carried out structural modification of the inner diameter gauge (see figure), and measured the mast while retaining the inner hole of the part, which improved the working efficiency and measurement accuracy and achieved the intended purpose.
