Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine for producing cylinder sleeves. Background Art
[0002] The cylinder liner is a cylindrical component embedded in the cylinder block. Together with the piston and cylinder head, it forms the combustion chamber of the internal combustion engine. Its primary functions include: absorbing piston thrust, reducing cylinder block wear, and extending its service life. It also helps dissipate heat from the cylinder, maintaining normal engine operating temperatures. It also facilitates repair and replacement, reducing maintenance costs. The production process for cylinder liners often involves cutting a long, tubular steel component into multiple sections according to production requirements, and then further processing the shorter sections.
[0003] Chinese utility model patent application number 2023205431944 discloses a steel pipe cutting device. The device comprises a cutting table equipped with a positioning mechanism, a fixing mechanism, and a cutting mechanism. The positioning mechanism comprises two strip plates, a first threaded rod, a first motor, a positioning baffle, two limit plates, and a sample steel pipe. The two strip plates are fixedly mounted on the top of the cutting table. However, since the device primarily secures the steel pipe via the fixing assembly on the first yoke, leaving the other end of the pipe unfixed, the pipe is susceptible to tilting and deflection due to stress during cutting.
