Reinforcing steel bar sleeve size detection device and reinforcing steel bar sleeve automatic detection system

The invention belongs to the technical field of equipment for measuring diameters, and particularly relates to a reinforcing steel bar sleeve size detection device and a reinforcing steel bar sleeve automatic detection system. The reinforcing steel bar sleeve size automatic detection device comprises a mounting main body, and an inner shape detection mechanism, an outer shape detection mechanism and a sleeve rotary clamping mechanism which are assembled on the mounting main body, and the inner shape detection mechanism comprises a detection rod and a spectrum confocal sensor mounted on the detection rod; the spectrum confocal sensor moves up and down and rotates along with the detection rod to scan the inner wall of the reinforcement sleeve to be measured so as to measure the inner diameter of the reinforcement sleeve; the appearance detection mechanism comprises a visual detection camera and a light source which can move up and down relative to the mounting main body, the visual detection camera and the ligh
