Engine Spare Parts Core Components

The engine is the "heart" of the vehicle. The development of the car 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 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., 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.

Using 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, and then with the main bearing hole combination finishing. Tank hole processing: the general use of drilling, 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, Engine Spare Parts the current process often used guns for processing.

Connecting rod shape irregular and more complex, Engine Spare Parts easy to achieve positioning, the size of the head is slender shaft connection, easy to deformation; size tolerance, shape and position tolerance, surface roughness and other requirements are higher. The processing of the connecting rod follows the first after the hole, the first principle after the benchmark. The connecting rod is a relatively rigid part, so the positioning clamping should reduce the deformation of the processing accuracy of the impact.

Linkage processing technology (also known as connecting rod cracking) as a manufacturing process, and gradually applied to large-scale production areas. Engine Spare Parts Linkage cracking is a new technology for the separation of split rods and connecting rods. It has the characteristics of novel design, economic operation and remarkable benefit.
