Step 5 is passed drill bit second inclined oil hole of air processed from the second pilot hole.
Adopt cartridge housing inclined oil hole of air fixture for processing of the present invention and processing method, broken away from the constraint by five-axis machine tool processing inclined oil hole of air, can adopt common driller processing, greatly reduce processing cost, and location is convenient, accurate, the crudy that has guaranteed cartridge housing inclined oil hole of air, has improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of cartridge housing;
Fig. 2 is that cartridge housing is arranged on the schematic diagram on cartridge housing inclined oil hole of air fixture for processing of the present invention;
Fig. 3 is the top view of base in Fig. 2;
Fig. 4 is the top view of Fig. 2 transit plate.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
Referring to Fig. 2-4, cartridge housing inclined oil hole of air fixture for processing of the present invention comprises base 10, flap 20 and core 30, described base 10 is provided with the first bracing frame 11, the second bracing frame 12 and hinged seat 13, and described hinged seat 13 is between described the first bracing frame 11 and the second bracing frame 12; One side and the described hinged seat 13 of described flap 20 are hinged, and can rotate around described hinged seat 13, described flap 20 can turn to respectively on described the first bracing frame 11 and the second bracing frame 12 and by the first bracing frame 11 and the second bracing frame 12, be supported respectively, and cartridge housing is fixed on described flap 20; Described core 30 is provided with the first pilot hole 31 and the second pilot hole 32, and described the first pilot hole 31 and the second pilot hole 32 are corresponding with two inclined oil hole of air 101,102 to be processed on cartridge housing 100 respectively, and described core 30 is fixed in the centre bore of cartridge housing 100.
In described the first pilot hole 31 and the second pilot hole 32, be embedded with respectively drill bushing 41,42, drill bushing 41,42 can be drill bit guiding and accurately locate during boring, have drill bushing 41,42 protection drill bits, the problem of drill bit sideslip while having avoided boring when boring.
When described flap 20 turns on described the first bracing frame 11 while being supported by the first bracing frame 11, described the first pilot hole 31 is perpendicular to horizontal plane, at this moment can process inclined oil hole of air 101, when described flap 20 turns on described the second bracing frame 12 while being supported by the second bracing frame 12, described the second pilot hole 31, perpendicular to horizontal plane, at this moment can be processed another inclined oil hole of air 102.
Cartridge housing inclined oil hole of air processing method of the present invention, adopts above-mentioned fixture to carry out, and comprises the steps:
Step 1, is fixedly mounted on cartridge housing 100 on flap 20, and core 30 is fixedly mounted in the centre bore of cartridge housing 100.Cartridge housing 100 can be with bolts with flap 20, and bolt can pad top board while connecting.Core 30 is inserted in the centre bore of cartridge housing 100, and is fixed by screws on cartridge housing 100, then positions by pin.
Step 2, rotates flap 20 to described the first bracing frame 11, and flap 20 is fixedly connected with described the first bracing frame 11, if Fig. 2 middle (center) bearing shell 100 is as shown in solid line part.This is fixedly connected with mode and can adopts bolt and/or bearing pin to be fixed.
Step 3, by drill bit from the first pilot hole 31 through first inclined oil hole of air 101 is processed, after completion of processing, remove being fixedly connected with of flap 20 and the first bracing frame 11.
Step 4, rotates flap 20 to described the second bracing frame 12, and flap 20 is fixedly connected with described the second bracing frame 12, if Fig. 2 middle (center) bearing shell 100 is as shown in dotted portion.This is fixedly connected with mode and can adopts bolt and/or bearing pin to be fixed.
Step 5 is passed drill bit second inclined oil hole of air 102 processed from the second pilot hole 32.
After completion of processing, remove being fixedly connected with of flap 20 and the second bracing frame 12, and cartridge housing 100 is pulled down.
Owing to adopting cartridge housing inclined oil hole of air fixture for processing of the present invention, can holing vertically downward, it is convenient and accurate to locate, and has guaranteed the crudy of cartridge housing inclined oil hole of air, and having solved inclined oil hole of air is the difficult processing of space oilhole, difficult its location dimension, the problem of positioning precision controlled.
Because being holes vertically downward, broken away from the constraint by five-axis machine tool processing inclined oil hole of air, change by common driller and process, greatly improved the machinability of this part, and five-axis machine tool cost is up to a hundred, up to ten million, system is huge, operating cost is higher, and common driller is cheap, system is simple, and operating cost is lower, by the conversion of machining tool, thereby greatly reduce the processing cost of part.
