Engine Spare Parts Development Of

The engine is the "heart" of the vehicle. Engine Spare Parts The development of the car has a direct relationship with the progress of the engine. Engine Spare Parts The engine is mainly composed of five key components, including cylinder block, cylinder head, crankshaft, camshaft, connecting rod and so on, Engine Spare Parts so these core parts The processing of automotive engine manufacturing as the key.

Cylinder, cylinder head as the engine of the core components, Engine Spare Parts is almost all the engine manufacturers must-made pieces of the project. At present the cylinder, cylinder head and other box parts of the mechanical development trend is to CNC machine tools and processing center composed of flexible production line gradually replaced by the combination of machine-based rigid production line. Engine Spare Parts In order to meet the needs of mass production, has developed a box-type flexible manufacturing unit (FMC) and a number of processing center composed of flexible processing system (FMS), to adapt to different varieties and batches of manufacturing needs. With the development of CNC control system and the development of new tool materials, Engine Spare Parts high-speed modular processing center in the 1990s to achieve a breakthrough, by the high-speed machining center composed of flexible processing system has been widely used in actual production.

Cylinder is the bearing of all parts of the overall bearing, Engine Spare Parts the cylinder structure in common is a similar hexahedral box structure, thin wall, processing surface, the hole is more, is a typical box parts, the main processing cylinder hole, the main Bearing holes, camshaft holes, etc., Engine Spare Parts there are lubricating oil channel, cooling waterways, installation screw holes and other holes, a variety of joints, sealing with a small table and small plane, their processing accuracy directly affect the engine assembly accuracy and work Performance, at the same time, in order to improve the body stiffness and strength, Engine Spare Parts but also distribution of many ribs.

Cylinder hole processing: the use of rough boring, semi-fine boring and fine boring, honing method of processing. The main bearing hole processing: Engine Spare Parts the general use of rough processing semi-circular hole, and then combined with the camshaft hole finishing. Camshaft hole processing: the general use of rough boring, and then with the main bearing hole combination finishing. Tank hole processing: the general use of drilling, Engine Spare Parts expanding (boring) and reaming of the processing methods. Main oil hole processing: the traditional processing method is the use of twist drill grading feed processing, the processing of poor quality, low production efficiency, the current process often used guns for processing.

Cylinder head shape is generally hexahedron, the Department of porous thin-walled parts, which have valve seat hole, valve duct hole, a variety of light holes and threaded holes, Engine Spare Parts camshaft holes and so on. The cylinder head of the gasoline engine has a spark plug hole, and the diesel engine cylinder head has an injector hole.

According to the number of cylinder head in an engine can be divided into the overall cylinder head and split cylinder head and so on. A cylinder head, Engine Spare Parts which covers only one cylinder, is covered with two or more cylinders called a block cylinder head (usually a two-cylinder cover, Engine Spare Parts three-cylinder cover), covering all cylinders called the overall cylinder head (usually Four-cylinder cover, six-cylinder cover)

The machining of the cylinder head is generally done by milling machine, and the hole system is generally used for drilling, expanding and hinging machining of radial drilling machine, combination machine and machining center. The duct and valve seat are used for freezing or normal temperature Press-fit method for loading and unloading, Engine Spare Parts temperature casting process commonly used displacement - pressure control method to control the assembly process.
