Description

Bearing bush assembly visualization error proofing device based on light ray mark Technical Field The invention relates to the technical field of assembly of bearing bushes of internal combustion engines, in particular to a visual error-proofing device for bearing bush assembly based on a light ray mark. Background The bearing bush of the internal combustion engine is a contact part of the sliding bearing and the journal, is in a tile-shaped semi-cylindrical surface, is very smooth, is generally made of bronze, antifriction alloy and other wear-resistant materials, and can be made of wood, engineering plastic or rubber under special conditions. The bearing shell is of both monolithic and split type, with monolithic bearing shells being commonly referred to as bushings. The integral bearing bush has two kinds of oil grooves or not and oil grooves. The bearing bush and the journal adopt clearance fit and generally do not rotate along with the shaft. The diameter requirement of the crankshaft journal is very strict, the actual size of the journal is measured and is subjected to red-blue grouping after the crankshaft is machined, the general size is in a blue group with lower tolerance, the size is in a red group with upper tolerance, and the journal is marked by red-blue 2 paint pens respectively. When the internal combustion engine is assembled, the bearing bush assembly with the corresponding color is selected according to the color of the crankshaft journal, the blue bearing bush with thicker thickness is required to be installed on the blue bearing journal with the lower diameter, and the red bearing bush with thinner thickness is required to be installed on the red bearing journal with the upper diameter, so that the gap between the bearing bush and the crankshaft is ensured to be in a proper range, and the quality of products is ensured. If the thin bearing bush is wrongly assembled, the clearance is too large due to the fact that the thin bearing bush is assembled to the journal with the lower diameter, faults such as abnormal internal combustion engine and low engine oil pressure can be caused, otherwise, the clearance is too small due to the fact that the thick bearing bush is assembled to the journal with the upper diameter, and serious faults such as poor friction force increase output performance of the internal combustion engine and even locking of a crankshaft can be caused. The assembly work of the existing bearing bush mainly comprises the steps that a worker observes color marks on a crankshaft journal, the worker memorizes journal information of a certain color by virtue of a human brain, and then the worker takes the bearing bush to mount the bearing bush on a corresponding journal, but the bearing bush is limited by the conditions that memory blurring, memory errors, memory forgetting and the like are easy to occur in the actual operation process, so that the mounting work of the bearing bush is difficult to be carried out by the correct crankshaft grouping information in the subsequent operation process of the worker; In order to reduce the risk of bearing bush installation errors to a certain extent, under the premise of continuous development of technology, two-dimension codes of a crankshaft are scanned in advance, grouping information of a crankshaft journal is transmitted to a computer screen of a bearing bush assembly post, workers need to look up the screen while installing the bearing bush, but the situation that the gear is easy to see wrong still exists, and the situation that the screen is frequently lifted up to influence the operation efficiency and the requirement of the assembly efficiency and the accuracy are not met, so that the visual bearing bush assembly error-proofing device based on light marks is developed. Disclosure of Invention In order to overcome the defects of the prior art, the embodiment of the application provides the visual error-proofing device for bearing bush assembly based on the light mark, which can realize the identification of cylinder data of an internal combustion engine before bearing bush assembly and irradiate light for identifying the bearing bush type at the corresponding bearing bush assembly position according to the identification result, so that on-site personnel do not need to independently memorize the type and the position of the bearing bush in the bearing bush assembly process, the use is more convenient, the assembly efficiency and the accuracy of the bearing bush can be effectively improved, the use effect is good, and the visual error-proofing device has good use prospect. The technical scheme adopted by the embodiment of the application for solving the technical problems is as follows: The utility model provides a bearing bush assembly visualization mistake proofing device based on light mark, includes supporting seat and suspension element: the upper end of the supporting seat is provided with a limiting piece for limiting the p
