Problems solved by technology
Basically, it takes 4 people to work for about 8 hours but can only complete the inspection and replacement of a 5-meter chain, so a lot of manpower and time are required
[0012] 2) No accurate measurement data
[0013] At present, the wear condition caused by chain wear can only be checked by the observation of maintenance personnel, and there is no quantifiable measurement data
[0014] 3) Passive maintenance afterwards
[0015] At present, the corresponding repair and remedial measures can only be carried out after a fault occurs, and more advanced preventive measurement data and maintenance cannot be carried out
[0016] 4) The maintenance efficiency is not high and the cost increases
[0017] Since there is no accurate measurement data, we can only roughly understand which section of the chain is worn out, and cannot guide which link, which chain plate or shaft pin is worn out
Some slightly worn chains are also removed and replaced together, making maintenance inefficient and costly

Embodiment Construction
[0040] The purpose of the present invention is to:
[0041] 1) It is possible to quickly check the wear condition during the operation of the chain. Rather than in the traditional technology, it can only be checked when the chain stops.
[0042] 2) It is necessary to be able to quickly obtain specific data, and be able to understand the severity of chain wear based on this data.
[0043] 3) It is necessary to refine the positioning accuracy to each link, instead of only giving a rough area as in the traditional technology.
[0044] Therefore, the generation process of chain wear is studied first. refer to figure 1 and figure 2 As shown, the structural diagram and cross-sectional diagram of the chain are revealed. The chain mainly includes the following parts: an outer chain plate 101, an inner chain plate 102, a roller 103, an axle sleeve 104 and an axle 105. The outer link plate 101 and the inner link plate 102 are spaced apart from each other, the wheel shaft 105 is c...

The invention discloses a chain abrasion inspection tool which comprises a set of measuring pieces, each measuring piece comprises a top and a bottom, and each bottom is narrower than each top. The width of each top of the set of measuring pieces enables the top of each measuring piece to be capable of being arranged on two adjacent shaft sleeves of a chain in an erecting mode, and the width of each bottom of the set of measuring pieces enables the bottom of each measuring piece to be capable of being arranged between the two adjacent shaft sleeves of the chain. The widths of the bottoms of the set of measuring pieces are different, and the widths of the bottoms of the measuring pieces at least include 208mm, 210mm and 213mm. The invention further discloses an inspection method using the inspection tool. According to the inspection method and the inspection tool, each chain link of the chain in the operation process can be inspected, specific data can be obtained immediately, and therefore the abrasion degree of the chain links can be judged.
Description
technical field [0001] The present invention relates to automobile production line equipment, more specifically, relates to a wear inspection method and inspection tool for chains used on the production line. Background technique [0002] In the automobile production line, the chain is one of the common equipment. The work of transporting parts from the previous station to the next station on the production line is usually done by the chain. The chain is a mechanical device, which will wear out after long-term use and needs to be replaced. If the severely worn chain is not found and replaced in time, there will be safety hazards, which will cause production stoppage or even production accidents. Especially for left and right synchronous chains running in harsh environments, such as pretreatment lines in the automotive industry, usually the left and right chains wear inconsistently during the use of the chains, resulting in asynchronous chains during operation, which makes th...
