Excuse me, what equipment is the automobile general assembly production line composed of?

Generally speaking, the general assembly process of the car mainly includes the following assembly lines: engine assembly line, door assembly line, instrument panel assembly line, interior assembly line and rear axle assembly line, and then thicken which is the final assembly line and the final inspection line.

General assembly workshop: driving, manual rolling machine, profile cutting machine, chainsaw, electric planer, CO2 protection welding machine, plate conveyor chain, turntable, electric feeding truck, manual shovel, pipeline seal inspection machine, vehicle detection line, synchronous lifting machine, etc.

The general assembly and final assembly line of electric vehicles usually includes the following main equipment: body welding equipment: used to weld various parts of the body together to form a body skeleton structure. Painting equipment:Including body painting and body parts painting, which are used to spray the body and body parts to provide protection and decorative effects.

The equipment of the whole vehicle assembly line mainly includes: conveying equipment used in the automobile assembly line, the online equipment of major assemblies such as engines and front and rear axles, various oil filling equipment, factory testing equipment and various special automobile assembly line equipment.

General assembly process: General assembly is the process of assembling the body, engine, transmission, dashboard, headlights, doors and other parts that make up the whole vehicle to produce the whole vehicle. With the help of computers and robots in the assembly operation of modern cars.

The principle of no cross-logistics route for people, parts and vehicles. The automobile assembly line is generally an organic whole composed of conveying equipment and special equipment.

Introduction to the production line of Chery ACTECO engine

The engine of Chery Tiger is The ACTECO series of high-efficiency and energy-saving engines independently developed by Chery. Compared with other brands of engines, this engine has the remarkable characteristics of "the highest torque at the same speed and the lowest torque at the same torque".

The second factory of Chery Engine, which produces ACTECO engines, adopts the latest technology and has a production line introduced from Germany and Italy, representing the highest international industrial level. The engine factory covers an area of 48,000 square meters. It adopts a mesh structure and is fully air-conditioned to ensure that high-precision equipment is produced under stable and clean conditions.

The excellent performance of the ACTECO engine has attracted the attention of the whole world. 7,000 units have been exported to the U.S. market. At the same time, an agreement has been signed with Fiat to supply 6-liter and 8-liter gasoline engines to Fiat cars produced at home and abroad, with an annual supply of more than 100,000 units.

At present, Chery Engine has 9 production lines and 200 CNC machining centers representing the highest level in the industry today. In the turbocharging,VVT, direct injection and other technologies have been comprehensively tackled. Its "Huadan" ACTECO series engines range from 0.8 liters to 2 liters, all of which meet the European No. 4 emission standard.

Chery ACTECO series engine is the first engine brand in China to be completely independent from design, research and development to production and manufacturing. Chery has completely independent intellectual property rights.

What are the common process problems in the engine assembly line

1. The sealing part should prevent "three leaks", that is, oil leakage and water leakage. Third, the cause of leakage is generally that the assembly process does not meet the requirements, or the seal is worn, deformed, aged and corroded. The sealing quality is often related to the selection, pre-tightening and assembly position of the sealing material.Once dismantled, all disposable seals must be replaced.

2. The assembly precautions of the main parts of the engine are as follows: the installation of the cylinder liner is a consumable part of the diesel engine. Its installation points include: (1) Put the cylinder liner without a water stop ring into the cylinder block to make it rotate flexibly without obvious shaking. At the same time, check whether the step size of the cylinder liner meets the specified range.

3. The sliding bearing, axle neck and friction surface of relative movement should be coated with engine oil during assembly. 07 During the assembly process, check whether there is any movement incoordination between the moving parts at any time. 08 It is necessary to clarify the nature and requirements of the fittings, and master the technical standards of over-over-over matching and gap matching.

What is the equipment for the automobile engine assembly production line?

The equipment of the automobile engine assembly production line includes the engine general assembly line and the cylinder head assembly line, including logistics system, pallet fixture, logistics trolley, tightening machine, marking machine, inspection machine, pressing machine, flipping machine, suspension crane, steel structure, lighting fan system and other equipment and tools.

The content of the work includes excess matching, welding, riveting, inlay, threaded connection, etc., so the workload is still very large (generally accounting for about a quarter of the entire automobile manufacturing workload).

Painting equipment: including body painting and body parts painting, which are used to spray the body and body parts to provide protection and decorative effects. Body assembly line: used for various functional parts and decorative partsAssembled into the car body, including the installation of battery packs, electric drive systems, seats, dashboards, doors and windows, etc.

General assembly process: General assembly is the process of assembling the body, engine, transmission, dashboard, headlights, doors and other parts that make up the whole vehicle to produce the whole vehicle. With the help of computers and robots in the assembly operation of modern cars.
