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 need be put down by the place's of processing ream by sphere, then carry out Drilling operation, can ensure the crudy in hole like this.Tuning for Controllable Pitch Propeller paddle flange spherical radius is little, and sharply, according to calculating, the flat degree of depth of ream reaches 35mm, and requires that bottom surface is plane in cambered surface change.If machining hole is through hole, then boring machine boring bar reverse drawing mode can be adopted to process, but for blind hole, when using common driller to process this product cambered surface hole, there is a following difficult problem:
1. blade blade face shape is special, and blade height is about 700mm, and the maximum arch face in blade face is about 320mm apart from flange cambered surface height, and drilling machine is serious with blade interference;
2. flange size is little, arches upward and flange machining hole spacing only 25mm in blade face, and sphere position clamping, location difficulty, easily run in processing;
3., by experiment, when cambered surface exemplar is holed, when the length of the bit is greater than 500mm, to rock scope comparatively large for drill bit, and the ream flat hole sideslip processed is serious, and perpendicularity is seriously overproof, does not reach drawing requirement;
4. hole location requires higher, and manual line precision is not enough.
In sum, paddle flange sphere hole adopts common process to realize, and need find novel processing mode.
Summary of the invention
The object of the invention is for above-mentioned present situation, provide one 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 add drill press socket, there is the Morse taper shank coordinated with drilling machine its upper end, and middle part is cylinder, and lower end has and coordinates Mohs joint with drill bit;
2) make special flat bottom bit, its head has Morse taper shank, and middle part is cylinder, and bottom drill bit, main cutting edge is flat sword, in the middle part of drill bit, cylinder is carved with hole ends line;
3) make guide-localization drill jig, drill jig has 2 locating holes and 1 pilot hole, drill jig profile is mated with blade cambered surface; Pilot hole, position of positioning hole are corresponding with paddle flange hole and ream flat hole position;
4) make cylinder locating piece, locating piece upper and lower end has the seam coordinated with guide-localization drill jig, paddle flange, and there is bolt hole at center;
5) make workbench, platform plane organizes T-slot more;
6) be locked on workbench with screw bolt passes drill jig, locating piece, paddle flange nut locking, drilling machine is installed and is added drill press socket, special flat bottom bit, and drill bit, through location drill jig pilot hole, starts the blind hole in machine tooling cambered surface.
Due in the middle part of flat bottom bit without cutting edge, can not drill jig be damaged during boring, also play well location and to hold concurrently guide effect.The present invention can reduce drill bit processing sphere sideslip, and crudy is good, precision is high, efficiency is high.
Special horizontal subdrilling centriciput of the present invention, without cutting edge, can not damage drill jig during boring, also plays the double guide effect in well location.The present invention can reduce drill bit processing sphere sideslip, and crudy is good, precision is high, efficiency is high, is applicable to the processing in all cambered surface holes.

Detailed description of the invention
The present invention is Problems existing when solving common driller processing cambered surface hole, mainly finds applicable cutter, installation way and positioning tool.Concrete steps of the present invention are as follows:
1) making adds drill press socket 3, length 700 ± 1mm, and upper end is that Mohs No. 5 taper shanks connect drilling machine chucks 1, and interfere for avoiding blade 2 blade face, add 500mm regional diameter in the middle part of drill press socket and be only φ 20mm, lower end is that Mohs No. 4 joints connect special flat bottom bit 4;
2) make flat bottom bit 4, drill bit overall length 200 ± 0.5mm, head is Mohs No. 4 taper shanks, middle part is φ 35mm cylinder, bit diameter φ 35mm, the length of the bit 35 ± 0.5mm, bottom drill bit, main cutting edge is processed as flat sword, in the middle part of drill bit, cylinder carves hole ends line;
3) make 40mm thick guide-localization drill jig 8, drill jig profile is mated with blade cambered surface, and pilot hole 10, left and right locating hole 12,13 position are corresponding with blade 2 flange hole and ream flat hole position.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.
