Abstract
本发明公开了一种OC分布器扩压管与喷气孔的同心度检测装置,由芯管与套管组成,芯管由两个对称的半圆形芯管半管拼合构成,拼合后芯管的内径为扩压管外径+1.6mm;芯管半管由上部用于套设在扩压管外的半圆形管体和下部用于伸入喷气孔内的凸台组成;管体外壁倾斜使芯管具有锥度,套管内壁的锥度与芯管的锥度一致,套管自芯管上端套在芯管外。先将套管沿扩压管底部套入使套管位于扩压管上部,将两个芯管半管对称放置的套设在扩压管外拼合成芯管并使芯管半管下部的凸台伸入喷气孔内,自芯管上端套入套管,如果芯管顺利套入套管内并使套管的上端面与芯管顶端齐平,则扩压管和喷气孔的同心度符合偏差要求。本发明检测装置测量结果精确,效率高。
The invention discloses a concentricity detection device of a diffuser tube and an air injection hole of an OC distributor, which is composed of a core tube and a casing. The inner diameter is the outer diameter of the diffuser tube + 1.6mm; the half-pipe of the core tube is composed of a semi-circular tube body on the upper part that is sleeved outside the diffuser tube and a boss on the lower part that extends into the jet hole; the outer wall of the tube The inclination makes the core tube have a taper, the taper of the inner wall of the sleeve is consistent with the taper of the core tube, and the sleeve is sleeved outside the core tube from the upper end of the core tube. First, insert the sleeve along the bottom of the diffuser so that the sleeve is located at the upper part of the diffuser, and then put the two core half-pipes symmetrically placed on the outside of the diffuser to form a core tube and make the lower part of the core half-pipe protrude. If the core tube is smoothly inserted into the casing and the upper end face of the casing is flush with the top of the core tube, the concentricity between the diffuser and the air injection hole is in line with the deviation Require. The detection device of the invention has accurate measurement results and high efficiency.
