Device for vulnerable part summit coordinate is rectified

The utility model relates to a device for vulnerable part summit coordinate is rectified, including two visual identification systems, two visual identification systems correspond one respectively to be absorbed plane A and one absorbs plane B, absorbs plane A and absorbs plane B mutually perpendicular, absorbs plane A and has a calibrating spot an and a calibrating spot b on the B of plane respectively with absorbing, makes plumb line l1 and l2 to the intersecting line L who absorbs plane A with absorb plane B by calibrating spot an and calibrating spot b, and l1 and l2 intersect 1 c on absorbing plane A and absorb plane B's intersecting line L the utility model discloses a correcting unit's simple structure, the volume is less, can assemble on the autoplant, can directly rectify after changing the vulnerable part, the time of rectifying is short, rectifies the precision height, the vulnerable part can be the syringe needle of point gum machine, the first-class part of spot welding of spot welder.
