Method for repairing and processing piston ring slot by grade through C6140A lathe
The invention provides a method for repairing and processing a piston ring slot by grade through a C6140A lathe, belongs to the method for processing the piston ring slot through a common lathe, and aims at solving the problem that the piston ring slot can only be repaired by grade by the manufacturer and the industrial and mineral enterprises cannot perform the repair. The method is that the grade of repair of the piston ring slot is determined according to the worm size of the piston ring slot, and then a piston ring at the corresponding grade is selected to determine the processing size of the piston ring slot in repair at grade. The method comprises the steps of manufacturing a special mould for the C6140A lathe for mounting a piston; selecting a turning tool; selecting reasonable processing turning factors; operating the C6140A lathe to repair the piston ring slot by grade. 1. Using C6140A lathe is used for piston ring groove level repair processing method, which is characterized in that: the clamping fixture for the clamping of a piston ring groove, (1), clamping fixture b (3), a turning tool. A fixture (1) is mounted in the piston (2) the skirt section, the clamping fixture b (3) install piston (2) top, selected tool cubic boron nitride, to be processed. 2. The stated according to Claim 1, using C6140A lathe is used for piston ring groove level repair processing method, which is characterized in that: a fixture whose diameter is 100 mm, a length of 150 mm of the steel column 45 #, with a diameter of 180 mm, a thickness of 30 mm the disc are welded together. Positioner one is installed in the piston skirt. 3. The stated according to Claim 1, using C6140A lathe is used for piston ring groove level repair processing method, which is characterized in that: the second selected for a diameter of 280 mm, a thickness of 30 mm of the disc, one end of the top of the piston are mounted, turning out a diameter of 240 mm, the thickness is 10 mm step, center punching. 4. The stated according to Claim 1, using C6140A lathe is used for piston ring groove level repair processing method, which is characterized in that: a turning tool lathe cubic boron nitride selected.
