Conventional image instrument auxiliary tooling cannot effectively position it, which will affect the accuracy of product detection. The utility model patent with Chinese patent publication number CN216781559U discloses an auxiliary tooling for image measuring instrument detection and positioning, which makes the sample adjustment port overlap with the large-size sample limit port and the small-size sample limit port respectively by moving the limit adjustment plate, so as to change the required limited size of the sample width, and set multiple pairs of caliper grooves equidistantly on the limit adjustment plate, and used to place the limit calipers. Multiple limit calipers are placed in different caliper grooves to change the required limited size of the sample length, so as to adapt to samples of different sizes. However, medicine bottle caps / plugs are usually cylindrical T-shaped structures with sizes ranging from 5mm to 32mm. They are easy to roll out when positioned using such tooling. In addition, the sizes of medicine bottle caps / plugs vary, and the diameters of the top and side surfaces of the same medicine bottle cap / plug are also different. The size of the limit opening must be adjusted each time, which makes the operation cumbersome and reduces the detection efficiency. Utility Model Content
