The piston production line piston processing can not only mill various pistons and shaped non-circular cross-section parts, but also has the milling function of general-purpose CNC machine tools. All surface processing of the piston can be carried out in a single clamping. Piston processing also has in-process inspection and main shaft bearing thermal deformation compensation functions.
A piston production line machine, which introduces the reduced working substance into the interior of the piston and discharges the working substance from several holes arranged on a part of the circle of the piston to the gap between the piston and the cylinder, thereby being equipped with an air bearing. In addition, this piston production line machine prevents the working substance in the piston from flowing back into the working space, and easily ensures reliability and provides a long service life.
A piston production line device used in an external combustion engine 10, comprising: a piston body 211; a pressure accumulation chamber 212, which is formed inside the piston production line body; an import part 214, used to introduce the reduced working substance into the pressure accumulation chamber; and holes 216, which are arranged on a circular portion 211b of the piston production line body, and extend from the pressure accumulation chamber to the gap between the piston production line body and the cylinder 22 of the external combustion engine.
wherein, the import part is arranged to connect with the pressure accumulation chamber of the working fluid in the import direction and connect in the opposite direction of the import direction, and the frictional resistance of the channel in the opposite direction in the import part is greater than the frictional resistance of the channel in the import direction.
Piston production line piston processing includes high-frequency, large-stroke micro-feed organization, parallel motor servo module, and convex elliptical piston processing. Intelligent control methods such as fuzzy reasoning self-calibration PID and discrete systems are adopted, making it comprehensively possess characteristics of high frequency response, large stroke, large thrust, and high bending stiffness.
The piston production line piston processing can mill various pistons, models, and other non-circular cross-sectional parts, and also has general-purpose CNC milling functions, and can complete the entire surface processing of the piston in one clamping. The piston processing also has functions of in-process inspection and spindle thermal deformation compensation.
