Description
Technical Field
The utility model relates to a six jar diesel engine jar hole honing's technology cylinder cap assembly belongs to diesel engine technical field.
Background
In the process of assembling the engine, the roundness and cylindricity of the cylinder hole of the engine are deteriorated due to the effect of the cylinder body on the tension of a cylinder cover bolt and the pressure of a cylinder cover, so that the engine oil consumption, the air leakage, the friction work, the abrasion of the cylinder hole, the tail gas emission, the service life and the like of the engine are influenced. To meet higher design and emissions requirements, the design axial force of the head bolts is also increasing with increasing engine detonation pressure, and therefore reducing cylinder bore deformation is also becoming more important.
Disclosure of Invention
The utility model aims to solve the technical problem that to the defect that prior art exists, a technology cylinder cap assembly that six jar diesel engine jar holes warp is provided.
In order to solve the technical problem, the utility model provides a six-cylinder diesel engine process cylinder cover assembly, which comprises a process cylinder cover body, a process cushion block and a cylinder gasket, wherein six cutter inlet and outlet light holes are arranged on the process cylinder cover body, and four process cylinder cover bolt holes and six connecting holes fastened with the process cushion block are arranged around each cutter inlet and outlet light hole; the process cushion blocks are fourteen in total, and each process cushion block is provided with a process cushion block bolt hole and three bolt holes connected with the process cylinder cover; the technical cylinder cover body and the technical cushion block are fixed on the cylinder body through bolts.
And a cylinder gasket is arranged between the process cushion block and the cylinder body, and a bolt sequentially penetrates through the process cylinder cover body, the process cushion block, the cylinder gasket and the cylinder body to be fastened.
The center line of the cutter in and out of the unthreaded hole is consistent with the center line of the cylinder hole.
The overall height of the process cylinder cover assembly is consistent with the height of an actual cylinder cover.
The technical cylinder cover body and the technical cushion block are both made of steel plates.
Has the advantages that: compared with the prior art, the utility model, have following advantage: the utility model provides a current six jar machines have the problem of out-of-round after cylinder body jar hole processing back reassembly goes up the cylinder cap in production, through calculating the true batch production cylinder cap of simulation contrast, use the out-of-round of technology cylinder cap 66% ~ 110%, the deformation of the true cylinder cap of approximate of ability by a relatively large margin, the effect is obvious on the returning of processing reassembling cylinder cap. The utility model discloses simple structure, it is convenient to process, keeps the same height with real cylinder cap, uses the same cylinder cap bolt and screws up technology, can simulate real cylinder cap state that compresses tightly by the maximum approximation.
