Description

Technical Field

[0001] The utility model belongs to the technical field of engine cylinder processing and relates to a constant-pressure honing device for a gasoline engine cylinder of a plant protection machinery. Background Art

[0002] Thermal load is an important factor causing increased engine oil consumption, especially in the recent hot sales of direct-drive sprayers. A large amount of feedback shows that the heat at the pump end will also transmit the temperature rise of the engine and affect the fuel consumption. Under the hot engine conditions of agricultural sprayers and general-purpose gasoline engines, the clearance between the piston and the movable ring is also an important cause of oil consumption. Therefore, improving the engine's cooling system, matching the piston and piston ring with the corresponding cylinder inner surface honing process, tolerance and precision are effective in reducing engine oil consumption, that is, reducing cylinder scuffing and oil burning, enhancing engine stability and improving economy. Important role, honing is to use the principle of error averaging method to improve the accuracy of the machined surface, so the accuracy requirements for the honing head itself are not very high, but the honing rod must be guided by the original machined surface (therefore, there are certain processing requirements for the previous process of honing the surface), and the trajectory of each reciprocating motion of the honing rod on the machined surface must not be repeated, so that the honing can achieve the ideal effect. The depth of the track formed is moderate. Under the appropriate temperature and oil pressure of the engine, the excess oil can flow back along this track, which is also called the groove under the action of gravity. Lubrication is better, and there will be no oil burning or cylinder pulling.

[0003] During cylinder honing, the existing hydraulic cylinder honing mechanism tends to generate a lot of noise during the honing process, which has a great impact on the working environment and needs to be improved. Summary of the Invention
