Summary of the invention
The technical problem to be solved in the present invention provides a kind of grinding attachment and method of ensuring the quality of products and fast oil scraper ring being carried out the oil scraper ring of grinding.
The technical scheme that technical solution problem of the present invention adopts is: the grinding attachment of this oil scraper ring includes the locating piece of a plurality of cylindrical magnetic metals, described locating piece is located in the oil scraper ring and described oil scraper ring matched in clearance, and the height H of described locating piece is less than the height h of oil scraper ring.
Another technical scheme that technical solution problem of the present invention adopts is: the method for grinding of this oil scraper ring, oil scraper ring is nonmagnetic annular thin wall part, use a kind of oil scraper ring grinding attachment, the grinding attachment of this oil scraper ring comprises the locating piece of a plurality of cylindrical magnetic metals, described locating piece is located in the oil scraper ring and described oil scraper ring matched in clearance, and the height H of described locating piece is less than the height h of oil scraper ring;
Operating procedure comprises:
A. clamping: a described locating piece packed into forms oil scraper ring grinding group in the described oil scraper annular distance;
B. place a plurality of described oil scraper ring grinding groups at the table top of surface grinding machine workbench;
C. start power supply, give the magnetic that adds of described workbench, the described workbench that adds magnetic is fixed on described oil scraper ring grinding group on the table top of described workbench by the absorption to described locating piece;
D. start emery wheel grinding-head, grinding is carried out on the oil scraper ring surface, the depth of cut is 0.08～0.1 millimeter;
E. cut off the electricity supply, workbench is demagnetized;
F, the oil scraper ring that will finish a face grinding take out from described locating piece, another side are sleeved on up form oil scraper ring grinding group on the described locating piece and be placed on the table top of described workbench;
G. a plurality of described oil scraper ring grinding groups are placed on the table top of described workbench;
H. repeat D～G step;
I. start emery wheel grinding-head, grinding is carried out on described oil scraper ring surface, the depth of cut is 0.01～0.02 millimeter;
J. cut off the electricity supply, workbench is demagnetized, take out the flat surface grinding that the oil scraper ring that is sleeved on the described locating piece is namely finished oil scraper ring.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, on surface grinding machine oil scraper ring is carried out grinding, once can process 50, improved production efficiency; 2, the oil scraper ring of this oil scraper ring grinding processing method is fixed on the table top of workbench by the magnetic metal locating piece that cooperates with it, select the rational depth of cut to oil scraper ring surfacing three times, can reach the requirement of oil scraper ring surface roughness and the depth of parallelism, accepted product percentage reaches 97%.
