Description

Technical Field

[0001] The utility model relates to a roller detection device, in particular to a semi-automatic roller detection platform. Background Art

[0002] Rollers are widely used in industrial conveying and are used in transmission, guiding and other structures. Before mechanical assembly, rollers usually need to be inspected. Currently, rollers are usually placed on a reference table, and each point of the roller is inspected one by one with a dial indicator. The defects are: first, the coaxiality of only one position of a roller can be measured at the same time, and the coaxiality of various positions of a roller cannot be inspected at the same time. The inspection speed is slow, the inspection accuracy is low, and inspection errors are prone to occur. Second, a testing table can only detect rollers of a single size and cannot be used for roller inspection of multiple sizes. Third, a workstation can only place rollers, inspect rollers, and remove rollers in sequence. It cannot operate simultaneously and the inspection speed is slow. Utility Model Content
