Embodiment Construction
[0015] Below in conjunction with accompanying drawing and example, the present invention is described in detail:
[0016] like figure 1 As shown in the figure, a tool for quickly detecting the shape and position tolerance of the shaft hole of the butterfly valve disc includes: a plug gauge with a key 1, a main beam 2, a limit sleeve 3, an adjustment beam 4, a plug gauge 5, and a nut 6. This tool is mainly used for the rapid detection of the shape and position tolerance of the shaft hole of the butterfly valve disc. The main beam 2 is an L-shaped metal part. The beam is machined with high-precision slender holes for matching the adjustment beam 4. The corner part of the main beam 2 is machined with through holes for installing the plug gauge with key 1; Adjustment beam 4 Both are L-shaped metal parts, the shape is similar to that of the main beam 2, the difference is that the beam is processed with a slender shaft, which matches the slender hole of the main beam 2, and the two...
