Problems solved by technology

[0003] In the existing technology, the heat treatment process of the cylinder liner obtains the processing technology of increasing the hardness and wear resistance of the inner surface of the cylinder liner by means of heating, heat preservation and cooling. Using this method, the operation is complicated, and the heat treatment effect is not good, and the treatment process is complex and numerous. Laser heat treatment is now used to improve the performance of the cylinder liner, but in the process of heat treatment with laser, the laser can not accurately control the same distance from the laser to the inner wall of the cylinder liner during the process of processing the inner surface of the cylinder liner, making The inner surface of the cylinder liner has uneven hardness due to different laser distances, and the distance between the laser and the inner surface of the cylinder liner cannot be adaptively adjusted according to the size of the cylinder liner, and the clamping and fixing cannot be performed according to the size of the cylinder liner, resulting in poor clamping stability. etc. In order to solve the above problems, an adaptive laser heat treatment device for cylinder liners is now designed

Description

technical field [0001] The invention belongs to the technical field of cylinder liner processing, and relates to an adaptive laser heat treatment device for a cylinder liner. Background technique [0002] The cylinder liner is a cylindrical part, which is placed in the cylinder block hole of the machine body, and is pressed and fixed by the cylinder head. The inner surface of the cylinder liner is directly affected by high-temperature and high-pressure gas, and always has high-speed sliding friction with the piston ring and piston skirt. The side thrust not only intensifies the friction on its inner surface, but also makes it bend. [0003] In the existing technology, the heat treatment process of the cylinder liner obtains the processing technology of increasing the hardness and wear resistance of the inner surface of the cylinder liner by means of heating, heat preservation and cooling. Using this method, the operation is complicated, and the heat treatment effect is not ...
