At first will fire pressure ring cover semi-finished product (8) is installed on the rotating disk (2), utilizing pressing plate (4) to clamp fastens, the rotating disk (2) that combustion pressure ring cover semi-finished product (8) will be installed utilizes two the first pin-and-holes (2-3) to position, choosing a type hole of the upper horizontal level of combustion pressure ring cover semi-finished product (8) cuts as first type hole (13-1), after the cutting of the first type hole (13-1) is complete, rotating disk is turned clockwise 12 °, until rotate to the Working position in combustion pressure ring cover semi-finished product (8) upper second type hole (13-2), utilize upper the first pin-and-hole of rotating disk (2) (2-3) to be positioned in upper corresponding the second pin-and-hole (1-2) of base plate (1), cut second type hole (13-2), by that analogy, after will firing pressure ring cover semi-finished product (8) upper 30 type holes (13) completion of processing, namely process combustion pressure ring cover finished product (5).
2. a kind of combustion pressure ring cover cutting clamper that utilizes according to claim 1 is realized the processing method that the combustion pressure ring overlaps, it is characterized in that: described combustion pressure ring cover cutting clamper also comprises four supporting screws (6), be processed with the second screwed hole (4-1) on the described pressing plate (4), the major diameter of thread of the second screwed hole (4-1) is 12mm, and the second screwed hole (4-1) that described supporting screw (6) passes on the pressing plate (4) removably connects with pressing plate (4).
3. a kind of combustion pressure ring cover cutting clamper that utilizes according to claim 1 and 2 is realized the processing method that the combustion pressure ring overlaps, it is characterized in that: described combustion pressure ring cover cutting clamper also comprises four pinching screws (7), be processed with waist hole (4-2) on the described pressing plate (4), the first screwed hole (2-4) that described pinching screw (7) passes waist hole (4-2) on the pressing plate (4) and rotating disk (2) successively removably connects pressing plate (4) and rotating disk (2).
