[0002] At present, bolt holes are provided on the upper and lower flange surfaces of the engine exhaust manifold, and threaded holes are drilled on the corresponding positions of the exhaust flange surface of the cylinder head. The exhaust manifold is installed by means of bolt positioning. The structure will bring inconvenience to disassembly. Only by removing all the bolts can the exhaust manifold be disassembled from the engine, and the increase of bolts will increase the probability of bolt slippage. Once the bolt slips, it will cause difficulty in disassembly. Delayed working hours

The invention provides an exhaust manifold installation structure and a method for assembling and disassembling the same. The exhaust manifold installation structure comprises a cylinder cover, an exhaust manifold and an installation bracket, wherein bolt holes are formed on flange planes on the upper and lower sides of the exhaust manifold. Key points are that: bolt installation holes are formed on the cylinder cover opposite to the flange plane on one side of the exhaust manifold; positioning holes are formed on the cylinder cover opposite to the flange plane on the other side of the exhaust manifold; bolt holes on the side of the exhaust manifold, which is opposite to the positioning holes, are U-shaped installation holes; positioning pin holes are formed at the two ends of the installation bracket, which are opposite to the positioning holes; and positioning columns which face and protrude from the inner side of the installation bracket are arranged at positions which are opposite to the U-shaped installation holes. Due to the exhaust manifold installation structure, precise positioning can be ensured, the exhaust manifold installation structure is convenient to install and disassemble, installed bolts are reduced, disassembling time is saved, and the sliding probability of the bolts is reduced.
Description
technical field [0001] The invention belongs to the technical field of engine manufacturing, and more specifically, the invention relates to an exhaust manifold installation structure and its installation and disassembly methods. Background technique [0002] At present, bolt holes are provided on the upper and lower flange surfaces of the engine exhaust manifold, and threaded holes are drilled on the corresponding positions of the exhaust flange surface of the cylinder head. The exhaust manifold is installed by means of bolt positioning. The structure will bring inconvenience to disassembly. Only by removing all the bolts can the exhaust manifold be disassembled from the engine, and the increase of bolts will increase the probability of bolt slippage. Once the bolt slips, it will cause difficulty in disassembly. Delayed working hours. Contents of the invention [0003] The object of the present invention is to propose a convenient installation and disassembly exhaust man...
