Background

In the mechanical field, the upper and lower shafts or two planes often have the requirement of coaxiality or parallelism, for example, in the installation and adjustment process of a capsule endoscope controller, the rotation axes of the upper and lower magnets are required to be ensured to be collinear (coaxiality requirement). This alignment of the concentricity is currently performed by a plumb, which, as shown in fig. 1a, marks the center point of the lower magnet, then hangs a plumb from the center of the upper magnet, and slowly translates the upper magnet so that the tip of the plumb points to the center point marked by the lower magnet, thus aligning the center line. However, this approach has many disadvantages, such as: 1. in the process of translating the upper magnet, the plumb bob is easy to swing, and when the plumb bob moves to a position, whether the plumb bob is aligned with the center mark can be observed only when the plumb bob is stable and motionless, so that the operation is extremely inconvenient and long in time consumption; 2. even if the plumb line is stabilized and the tip of the plumb is pointed to the central mark of the lower magnet, whether the surface of the central mark is vertical to the plumb line or not can not be ensured (as shown in fig. 1 b), if the plumb line is not vertical to the mark surface of the lower magnet, the core lines of the rotating shafts of the upper magnet and the lower magnet are not collinear, and the positioning is incorrect; 3. this method can only be used for the alignment of the coaxiality in the vertical direction, and cannot be applied to the positioning and alignment of the parallelism.
