Description

Technical Field

[0002] The engine cylinder liner is the abbreviation of cylinder liner. It is embedded in the cylinder barrel of the cylinder body and forms a combustion chamber together with the piston and cylinder head. It is an important component of the engine. Its performance and quality have an important impact on the overall performance and life of the engine. The main function of the milling device is to perform precise milling on the end of the cylinder liner to remove excess material, correct the shape or meet specific surface quality requirements. Through milling, it can ensure that the dimensional accuracy, surface roughness and shape accuracy of the cylinder liner end meet the design requirements, thereby improving the overall performance and reliability of the engine.

[0003] An engine cylinder liner end milling device disclosed in the Chinese utility model patent application disclosure specification CN110153797A, through the provision of an audible and visual alarm, is conducive to reminding the staff when the clamping force of the clamping block is too large. Through the provision of a PLC, it is conducive to improving the degree of intelligence and making it more convenient to use. Through the provision of a pressure sensor and a display, it is conducive to transmitting the pressure borne by the cylinder liner to the display, which is convenient for the staff to observe. Through the use of a cemented carbide cutter, it is conducive to improving its room temperature hardness and high temperature hardness, wear resistance, bonding temperature and oxidation resistance, and increasing work efficiency. However, the existing engine cylinder liner end milling device has a relatively simple structure and lacks a cooling structure for the milling device.
