Description

Detection tool

Technical Field

The utility model relates to the field of chain conveyors and detection thereof, in particular to a detection tool for detecting the relative position of sprocket pairs in a inverted tooth conveyor chain.

Background

Chain conveyors for automotive production generally use inverted tooth chains in their construction. The inverted tooth conveying chain has the advantages of space saving, no sliding and silence, reliable function, prolonged service life, firmness and durability and simple assembly/disassembly. Inverted tooth chains are usually centered on a sprocket with a guide plate, with a guide slot in the middle of the sprocket. When the chain is used, if the chain wheels on the left side and the right side are on the same line, the guide plate of the inverted tooth chain only plays a guiding role and does not increase extra force, otherwise, the guide plate on the chain plays a guiding role and faces extra force, and the chain is damaged and the service life of the chain is reduced.

In the prior art, in order to detect the relative positions of two sprockets, a laser tracker is generally used to acquire coordinates of three points on the side surface of each sprocket, so as to obtain the absolute positions of the two sprockets first, and then calculate the relative positions of the two sprockets. However, laser trackers are expensive and have stringent field space requirements, require debugging and are difficult to debug.
