Description
Technical Field
The invention relates to the field of chain detection equipment, in particular to an automatic chain detection machine.
Background
After the traditional chain in China is assembled into a strip by an assembling machine, the chain needs to be detected in order to ensure the quality of the chain. At present, most chain production plants still rely on the naked eyes and hand feeling to detect whether the chain is short of sheets, tight joints, left and right eccentric sheets, long and short pins, small and large tubes and the like. If quality problems occur, the unqualified chain is manually fixed on a positioning frame, the pin shaft is broken by an iron hammer and a link disassembling nail to be repaired or the qualified parts are replaced, and then the chain is linked. Because the whole process is formed by beating with an iron hammer by artificial naked eyes, the problems of precision and missed detection always exist, the quality problem of one hundred percent cannot be achieved, and meanwhile, the problems of low artificial speed and low efficiency also exist.
Although some chain detection devices are disclosed in the prior art, these detection devices can only detect a certain link of the chain, such as tight link, left and right piece eccentricity, etc., but cannot form a complete detection system capable of matching front and rear links and continuously detecting.
Meanwhile, when the conventional chain detection device detects a specific link, the detection precision is low and the omission factor is high due to the unreasonable structural design of the chain detection device.
Disclosure of Invention
In order to solve the technical problem, the invention provides an automatic chain detection machine. The automatic chain detector can realize the omnibearing continuous detection of the chain on one device, each detection unit has ingenious and novel structure, the detection sequence of each detection unit is reasonable, and the whole automatic chain detector has high detection precision, low omission ratio and high working efficiency.
The specific technical scheme of the invention is as follows: the utility model provides a chain automated inspection machine, includes whole frame, locates control electronic box in the whole frame, locate panel, chain drive mechanism at whole frame top and locating on the panel and according to chain cleaning mechanism, tight section detection mechanism, eccentric plate detection mechanism, lack piece detection mechanism, short round pin detection mechanism and big small pipe detection mechanism that the detection order set gradually.
