Description

Technical Field

[0001] The utility model relates to a defect detection structure device for a dead joint of a chain saw chain. Background Art

[0002] As the basic component of mechanical transmission, the chain saw chain has the advantages of high transmission rate, high efficiency and long life, and is widely used in various engineering machinery fields. At present, there are detection devices for chain saw chains, which can be roughly divided into several types. The first type is manual detection. Most domestic chain manufacturers still remain at the level of manual detection for the detection of chain dead knot problems after the chain components are assembled. The dead knot defects of the chain saw chain need to be detected by the eyes and hands of the inspectors; the second type is mechanical contact detection. This detection method relies on the lever structure in the chain saw chain and the mechanical components to enable the sensor to obtain the corresponding detection results. The detection speed is slow and the reliability is low. In addition, the probe wears more during the measurement process, the structure is complicated and easy to damage; the third type is non-contact detection. During the detection, the measuring component does not need to be in direct contact with the chain saw chain to obtain the detection result. The common method is to use image sensors to detect dead knot defects in the chain saw chain. This is also the most widely used method in the current automatic chain detection. However, the chain is prone to rollover during the dead knot detection, which affects the detection effect. Utility Model Content

[0003] The utility model aims to provide a chain saw chain dead joint defect detection structural device which does not overturn when the chain is detected at a dead joint station and has high detection efficiency.
