Problems solved by technology
Therefore, the detection work intensity is high, the efficiency is low, the effect is poor, and the cost is high, and it is increasingly unable to meet the requirements of mass production.
Although some chain detection devices have appeared on the market, which can partially replace manual detection work, the detection accuracy of the chain detection devices in the prior art is low, and accidents of missed detection are prone to occur.

Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The embodiments described here are only used to explain the present invention, and are not intended to limit the use of the new model.
[0038] Before explaining the missing detection device of the chain roller sleeve of the present invention, the structure of the roller chain in the prior art will be briefly described. Such as figure 1 and figure 2 As shown, the roller chain mainly includes an outer piece 1, an inner piece 2, a pin shaft 3, a sleeve 4 and a roller 5, wherein: the sleeve 4 is set on the pin shaft 3, and the roller 5 is set on the sleeve 4, The inner piece 2 connects two pin shafts 3 covered with sleeves 4 and rollers 5 from both sides to form a chain link. The distance between the two pin shafts 3 is called the chain link pitch. The outer p...

The invention provides a chain roller sleeve defect detection device which belongs to a chain detection device, and comprises a base and a lever, wherein a fulcrum is arranged on the base, one end of the lever is provided with a detection head, the other end of the lever is provided with a displacement induction device, the distance between the displacement induction device and the fulcrum is larger than the distance between the detection head and the fulcrum, and an elastic element which enables a contact surface of the detection head and a chain to be detected to be closely contacted with each other is also arranged on the lever. According to the chain roller sleeve defect detection device, the distance between the displacement induction device and the fulcrum is larger than the distance between the detection head and the fulcrum, so that the displacement induction device can sense the infinitesimal displacement of the detection head which is magnified by the lever, consequently, the detection device not only can substitute the manual detection, but also has high detection precision, and wrong detection and omission detection cannot be caused.
Description
technical field [0001] The invention relates to a chain detection device, in particular to a chain roller sleeve missing detection device. Background technique [0002] The chain is a multi-purpose mechanical basic part composed of rigid components and a flexible system. It is mainly used to meet the functional requirements of transmission, transportation, and pulling. Among them, the roller chain is a widely used chain type, which is mainly composed of five elements: outer piece, inner piece, pin shaft, sleeve and roller. Due to the small size, variety and complex assembly of roller chain elements, missing elements (large and small tubes) are prone to occur in the production of roller chains, such as lack of sleeves and / or rollers. [0003] At present, most chain manufacturers in China are still at the level of manual inspection for the detection of missing parts after assembly of chain components, and need to detect the integrity of the chain through the eyes and hands of...
