Description
Technical field
The present invention relates to a kind of marine distance adjusting blade flange cambered surface blind hole processing method.
Background technology
When cambered surface hole, the first step is that sphere need be put down by processing place ream, carries out Drilling operation again, can guarantee like this crudy in hole.Tuning for Controllable Pitch Propeller blade flange spherical radius is little, and cambered surface changes sharply, and according to calculating, the flat degree of depth of ream reaches 35mm, and to require the bottom surface be the plane.If machining hole is through hole, then can adopts the anti-mode of drawing of boring machine boring bar to process, but for blind hole, have a following difficult problem when using common driller to process this product cambered surface hole:
1. blade blade face shape is special, and blade height is 700mm approximately, and the maximum arch face in blade face is apart from the about 320mm of flange cambered surface height, and drilling machine is serious with blade interference;
2. flange size is little, arches upward and flange machining hole spacing 25mm only in the blade face, and sphere position clamping, location difficulty, easily runs in the processing;
3. by experiment, when the cambered surface exemplar is holed, the length of the bit during greater than 500mm drill bit to rock scope larger, the flat hole of the ream that processes sideslip is serious, perpendicularity is seriously overproof, does not reach drawing requirement;
4. hole location is had relatively high expectations, and manual line precision is not enough.
In sum, blade flange sphere hole adopts common process to realize, needs to seek novel processing mode.
Summary of the invention
The objective of the invention is for above-mentioned present situation, provide a kind of and can reduce drill bit processing sphere sideslip, the marine distance adjusting blade flange cambered surface blind hole processing method that crudy is good, machining accuracy is high.
The implementation of the object of the invention is, marine distance adjusting blade flange cambered surface blind hole processing method, and concrete steps are as follows:
1) make and to add drill press socket, it is cylinder that there are the Morse taper shank that cooperates with drilling machine, middle part in its upper end, and the lower end has and cooperates the Mohs joint with drill bit;
2) make special-purpose flat bottom bit, its head has Morse taper shank, and the middle part is cylinder, and drill bit bottom main cutting edge is flat sword, and cylinder is carved with the boring terminated line at the drill bit middle part;
3) make the guide-localization drill jig, 2 locating holes and 1 pilot hole are arranged on the drill jig, drill jig profile and blade cambered surface coupling; Pilot hole, position of positioning hole are corresponding with blade flange hole and the flat hole site of ream;
4) make the cylinder locating piece, the locating piece upper and lower end has the seam that cooperates with guide-localization drill jig, blade flange, and there is bolt hole at the center;
5) make workbench, the T-shaped groove of many groups is arranged on the platform plane;
6) be locked on the workbench with nut locking with screw bolt passes drill jig, locating piece, blade flange, drilling machine is installed and is added drill press socket, special-purpose flat bottom bit, and drill bit passes location drill jig pilot hole, starts the blind hole on the machine tooling cambered surface.
Because drill jig without cutting edge, can not damaged during boring in flat bottom bit middle part, also play the guide effect of holding concurrently of good location.The present invention can reduce drill bit processing sphere sideslip, and crudy is good, precision is high, efficient is high.
Special horizontal subdrilling centriciput of the present invention can not damage drill jig without cutting edge during boring, also plays the guide effect of holding concurrently of good location.The present invention can reduce drill bit processing sphere sideslip, and crudy is good, precision is high, efficient is high, is applicable to the processing in all cambered surface holes.

The specific embodiment
The present invention is the problem that exists when solving common driller processing cambered surface hole, mainly is to seek cutter, installation way and the positioning tool that is fit to.Concrete steps of the present invention are as follows:
1) making adds drill press socket 3, length 700 ± 1mm, and the upper end is that No. 5 taper shanks of Mohs connect drilling machine chuck 1, interferes for avoiding blade 2 blade faces, adds drill press socket middle part 500mm regional diameter and only is φ 20mm, the lower end is that No. 4 joints of Mohs connect special-purpose flat bottom bit 4;
2) make flat bottom bit 4, drill bit overall length 200 ± 0.5mm, head are No. 4 taper shanks of Mohs, the middle part is φ 35mm cylinder, bit diameter φ 35mm, the length of the bit 35 ± 0.5mm, drill bit bottom main cutting edge is processed as flat sword, and cylinder carves the boring terminated line at the drill bit middle part;
3) make the thick guide-localization drill jig 8 of 40mm, the drill jig profile is mated with the blade cambered surface, and pilot hole 10, left and right locating hole 12,13 positions are corresponding with blade 2 flange holes and the flat hole site of ream.Pilot hole 10 is φ 35.2 * 40mm through hole, and left and right locating hole 12,13 is φ 40/ φ 20.2 * 40mm through hole.
4) make 2 cylinder locating pieces 7, there is the φ 40 * 20mm seam that cooperates with the guide-localization drill jig locating piece 7 upper ends, and there are φ 52 * 30 seams that cooperate with blade 2 flanges the lower end, and there is the M20 bolt hole at the locating piece center.
