Detailed description of the invention
Better understand the present invention for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the present invention, following is only exemplary do not limit protection scope of the present invention.
As shown in Figure 1, 2, aircraft of the present invention is disassembled component reset and is installed Quick drilling tool, comprises support, clamping device, locking positioning device and cylinder 20.
The L bracket 7 that support comprises U-shaped support 1 and is fixed on U-shaped support, L bracket 7 is threaded with U-shaped support 1 by the screw flight 6 on it and the U-shaped support screwed hole 2 on U-shaped support 1.
The free end of the cross bar of L bracket 7 offers the clamping screwed hole 10 of a vertical direction, and clamping screw 12 is threaded with it through clamping screwed hole 10 and realizes clamping screw 12 moving up and down in L bracket 7; The lower end of clamping screw 12 is provided with grip base 16 for the clamping to section bar, the lower surface of grip base 16 offers a base groove 15 in centre position along its length, for holding and cushioning to drill bit spilling part during drilling, prevent from damaging during drill bit drilling grip base; More fit after clamping to make grip base 16 and Surface of profile, the lower end of clamping screw 12 is fixed with bulb 13, grip base 16 is arranged a bulb groove 14, bulb is movably set in bulb groove, the coordinating of bulb and bulb groove grip base 16 can be realized low-angle in rotary moving; The through hole 11 of a horizontal direction is offered in the top of clamping screw 12, through hole is provided with driving lever 9, through hole 11 and driving lever 9 form matched in clearance, the function that through hole 11 provides spacing for driving lever 9, supports and move axially, the two ends of driving lever 9 are provided with driving lever spacing 8, complete the restriction of position when driving lever 9 moves, avoid driving lever slippage.Above-mentioned driving lever 9, clamping screw 12, bulb 13, bulb groove 14 and grip base 16 form clamping device.
Cylinder 20 to be movably set on U-shaped support 1 and to be positioned at immediately below clamping device, the two ends of cylinder 20 are respectively arranged with cylinder screwed hole 22, be movably set in U-shaped support 1 on through the through hole 24 be arranged on U-shaped support 1 by cylinder 20 by screw 23, through hole 24 forms friction pair with the polished rod part of screw 23 and cylinder 20 can be rotated.The present embodiment middle column body 20 is preferably positive six prisms, its each side is evenly equipped with several pilot holes 19, on two often adjacent sides, on different, every two the just right sides of the diameter of pilot hole, the diameter of pilot hole is identical, pilot hole on every two just right sides communicates one by one, namely comprise the pilot hole of three kinds of different-diameters in the present embodiment, aircraft disassemble member arts relatively conventional be 1/8,3/16,1/4 3 kind of diameter specifications; On each side of cylinder 20, the pitch of holes of pilot hole is 4-6 times of pilot hole diameter, meets the requirement of securing member distribute spacing, can realize the rapid batch preparation of the fastener hole confirmed without the need to prescoring; The inwall of each pilot hole 19 and the column side face at place perpendicular to realize vertically-guided function.
Locking positioning device comprises two bayonet locks 17 above the free end that to be arranged at inside U-shaped support 1 two symmetrical reeds 5, to be arranged at inside U-shaped support 1 and to be positioned at reed 5 and is arranged at two ratchets 21 at cylinder 20 two ends, and ratchet can realize single direction rotation and latch functions for cylinder 20.Described each reed 5 be fixed on by reed screw 3 be arranged on U-shaped support medial surface reed base 4 on; Each bayonet lock 17 is arranged at inside U-shaped support by bayonet lock screw 18, the support that bayonet lock screw 18 provides circumferencial direction to rotate for bayonet lock 17.
In the present invention, U-shaped support 1, L bracket 7, driving lever 9, clamping screw 12, bulb 13, grip base 16, bayonet lock 17, cylinder 20 and ratchet 21 all adopt No. 45 carbon steels to make, and have good machinability and durability; Reed screw 3, bayonet lock screw 18 and screw 23 adopt standard component made in Great Britain, or use the 17-7PH steel meeting Boeing standard, and this material easily obtains and technological specification is secure; Reed 5 adopts 65 manganese steel to make, and the coefficient of stiffiness is high, and fatigue durability is good.
The operation principle of drilling tool of the present invention:
The pore size of the workpiece of holing as required, side consistent with workpiece pore size on cylinder 20 is rotated to just upward, workpiece is placed on this side, then driving lever 9 is rotated, driving lever drive clamping screw 12 forms wheel shaft and rotates around clamping screwed hole 10, realize moving up and down of clamping screw 12 and grip base 16, situation adjustment is looked according to different workpiece, because bulb 13 can rotate in bulb groove 14, namely, grip base 16 is realized low-angle in rotary moving, grip base 16 and surface of the work can be made to fit completely.
After workpiece is clamped, the drill bit matched with pilot hole 19 diameter is placed on air drill, drilling is done in the drill bit just right side, side that fits with surface of the work from cylinder 20, ensure that drill bit is concentric with pilot hole 19, drill bit does feeding drilling along the inwall of pilot hole 19, because pilot hole 19 inwall is vertical with cylinder 20 surface, pilot hole achieves vertically-guided function, therefore when drill bit does feeding drilling on workpiece, drawbore is vertical with surface of the work, and the waste material that drill bit overflows can enter in base groove 15.
When needing the workpiece of drilling different pore size, just need to change different pilot holes 19, along direction as shown, be rotated counterclockwise cylinder 20, in rotary course, ratchet 21 and bayonet lock 17 friction pair formed under the preload pressure of reed 5 when rotating completes locking positioning function after being also finally rotated in place, and ratchet 21 can ensure that when ad-hoc location locking any one side of cylinder 20 and surface of the work fit tightly.
Above only describes general principle of the present invention and preferred embodiment, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection scope of the present invention.
