Automotive endoscope function and testing procedures
What is an automotive borescope?
Automotive endoscopes are actually one type of industrial endoscopes. Simply speaking, they are instruments that detect and view the internal parts of a car. Generally speaking, many auto repair shops and 4S shops now use this instrument, because, during the maintenance, some of the more secret parts of the car are more difficult to observe with the naked eye, so it is necessary to monitor the inside by means of the instrument. For example, the carbon deposit of the engine and the dirty case of the air conditioner are useful for both inspection and repair.
Automotive videoscope is designed specifically for the automotive manufacturing and maintenance industries. It is mainly used for detecting and diagnosing the wear, carbon deposits, blockages, etc. of automobile engines, cylinders, fuel pipes, engines, mufflers, conveyor systems, differentials, water tanks, fuel tanks, gearboxes, etc., which greatly reduces the repair time and cost. It also avoids damage caused by multiple disassembly and assembly of the machine. It also greatly demonstrates its positive effects on the cleaning and maintenance of automotive engines.
The automotive endoscopy test procedure
1. We need to understand the internal structure of the car, check the specific content and location, and follow the procedures to expand the relevant link instruments and check the power supply.
2. Select the appropriate probe to enter the internal components of the vehicle to be tested. Before the test, it should be clear that obstacles, burrs, etc. in the channel may hinder and inspect the object of the probe.
Care should be taken during the inspection process to ensure that the probe reaches the specified part smoothly. If the probe encounters obvious resistance during the propulsion process, it should stop moving forward immediately. The probe should be slow when it exists. If it is stuck, it should not be pulled hard to avoid damage to the workpiece or probe.
The captured image can be photographed and recorded during the detection process, which is convenient for later processing and analysis.
After the test is completed, the probe should be cleaned and the instrument site cleaned as required.
The feature of yatkes articulating automotive borescope
1. Simple, flexible, compact and easy to carry, the soft, small and flexible insertion tube can reach any hidden parts that need to be inspected.
2, intuitive and accurate and easy to implement, and can detect the damage of internal components as early as possible, greatly facilitating the exclusion of safety hazards in the germination stage.
3. The compactness, portability, and mobility of the instrument itself can reduce the work intensity and improve work efficiency.
4. The repair cost is reduced, and the damage caused by multiple disassembly and assembly of the machine parts is avoided.
Use of car endoscopes
Automotive borescopes are mainly used to inspect automobile manufacturing and maintenance, precision machining, petrochemical, military manufacturing, small apertures in small equipment, internal conditions of small gaps, wear of mechanical gear parts, looseness, and quality inspection of grease pump.
Application of Industrial Endoscope in Automobile Inspection and Repair
Industrial endoscopes are new high-tech products designed and produced according to the inspection requirements of the inner surfaces of straight pipes such as petrochemicals, industrial machinery, electrical and electronic industries, and aerospace. Industrial endoscopes are also widely used in the automobile production and maintenance industry.
In the cleaning and maintenance of car engines, car endoscopes are also a good helper. The diagnosis of valve carbon deposits has always been a problem in the automotive repair industry. Generally speaking, there are two diagnostic methods in professional repair shops.
1. Traditional disassembly method
That is, take the engine apart and check if there is a carbon deposit. This is intuitive but time-consuming and laborious, and no matter what components are disassembled once, it will affect its performance more or less, reducing its service life.
2, Car endoscopy
Remove the spark plug or the injector and use an endoscope to observe the degree of carbon deposits on the valve. The main feature is that the formation and combustion process of the mixture in the combustion chamber and the working state of the cylinder, the gas valve and the piston crown at high temperature can be observed under the working condition of the engine, and the above image is identified by the crank angle by a high-speed camera. Record it. At the same time, it can be connected to a computer and can be called, slow-released, partially enlarged and interpreted at a certain time by means of corresponding image processing software. This visualization technique is not only a good assistant for automotive design and development but also a tool for automotive technology training and teaching.
Automotive endoscopes have been widely recognized by users in the auto repair industry, and its simple and flexible operation is an indispensable test and diagnostic tool in the auto repair industry.
Yateks Optoelectronic Industrial Endoscope integrates light, electricity, and image. N series video industrial endoscope is equipped with a high-resolution color image, which makes the image clearer, allowing the operator to use high-definition color images to observe the suspected points and faults. The part uses a unique image software processing system to freeze, enlarge, and analyze, greatly improving the accuracy of determining the fault location of the car.
1, piston and spark plug carbon check
The carbon deposit check can be judged by “disintegration”, that is, disassembling the car engine or observing the feedback voltage change, but these two methods have higher professional requirements, and using the car endoscope to check the car engine, it can pass the spark plug hole or spray The nozzle can directly observe various faults inside the cylinder.
2, the inner wall of the exhaust pipe
Checking the real shot of the exhaust pipe, it is obvious that there is a slight welding hole in the exhaust pipe wall.
3, Auto parts testing
It is obvious that there is a tiny welding hole in the exhaust pipe wall.
Detect whether there are cracks, pigmentation, etc. inside the auto parts. The measured hole is bent. The minimum diameter is 4MM, which cannot be directly observed.
4, Automotive casting inspection
In the inspection of automobile castings, it is mainly to check the internal impurities and trachoma of the product.
5, Engine cylinder
6, engine exhaust catalytic converter detection Figure 6 is Yatai Optoelectronics HIE high-definition video endoscope in the Dongfeng Automotive Technology Center to detect the exhaust catalytic converter
7, cylinder head detection
The foundry inspects the cylinder head of the cylinder for internal flaw detection to determine whether it is qualified.
In addition, automotive endoscopes can also be used in gearbox inspection, water tank, fuel tank inspection, fuel injection hole detection, etc.
Therefore, the automotive borescope is not only an artifact for car owners to understand the condition of the car, but also a new generation of maintenance tools for non-destructive testing of vehicles in the field of vehicle maintenance.
