Engine Spare Parts Development Trend

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

Cylinder, cylinder head as the engine of the core components, is almost all of the engine manufacturers must-made pieces of the project. At present the cylinder, Engine Spare Parts 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 replace the combination of machine-based rigid production line. 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. Engine Spare Parts With the development of CNC control system and the development of new tool materials, high-speed modular processing center in the 90's a breakthrough, composed of high-speed machining center flexible processing system has been widely used in actual production.

Cylinder is the bearing of all parts of the overall bearing, 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, 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: 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, Engine Spare Parts and then combined with the main bearing hole finishing. Tank hole processing: the general use of drilling, expansion (boring) and reaming the way of processing. Main processing of the main hole: 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, Engine Spare Parts the Department of porous thin-walled parts, which have valve seat hole, valve guide hole, a variety of light holes and threaded holes, camshaft holes and so on. Gasoline engine cylinder head with spark plug hole, diesel engine cylinder head with fuel 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. Engine Spare Parts (Usually a two-cylinder cover, three-cylinder cover) covering all cylinders, known as a single cylinder head (usually a cylinder head Four-cylinder cover, six-cylinder cover)

The machining of the cylinder head is generally done by milling machine, Engine Spare Parts and the hole system is generally used for drilling, Engine Spare Parts 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 generally use the displacement - pressure control method to control the assembly process.
