The specific embodiment:
At present, drilling machine is used quite extensively in the field of machining, but existing drilling machine adds man-hour its motion of main shaft for rotatablely moving and the vertical direction feed motion, 1), the transmission and the conversion (drill press spindle lacks the radial feed motion that is used for the boring inside groove) of motion will process the inside groove of dead eye with the drilling machine boring, the subject matter of existence has:; 2), the width of inside groove and degree of depth control; 3), the safety of inside groove boring blade is cut and is withdrawed from; 4), the stationarity of moving in the process; 5), the wearing and tearing of blade and replacing; 6), the cooling of blade and lubricated etc.The utility model has designed a kind of can be used for and has carried out the special fixture that boring processes the dead eye inside groove on the drilling machine at the problems referred to above, enables to address the above problem.As shown in Figure 1, it comprises boring cutter combination block 1, positioning component 2, boring bar cover 32 and boring bar axle 33, described boring bar axle 33 1 ends and drill press spindle join, adopt the Mohs awl to be connected between the two, quick and easy for installation, the other end places in the boring bar cover 32, connect with key 7, present embodiment adopts flat key to connect, can pass motion to boring bar axle 33 by drill press spindle, drive together rotation of boring bar cover 32 by flat key 7 then, key 7 and boring bar overlap to adopt between 32 keyways and are slidingly matched, make boring bar cover 32 in, can not hinder the bottom and top feed motion of boring bar axle 33 with 33 rotations of boring bar axle.Described boring bar cover 32 is by positioning component 2 location, and this positioning component 2 can place on the workpiece to be processed 5, to give whole anchor clamps location.Overlap 32 front ends at boring bar, boring cutter combination block 1 is housed, boring cutter sheet 11 is housed on it, can make it do radially to pass by the mobile of boring bar axle 33.Like this, by positioning component 2 location, driving boring bar cover 32, boring cutter combination block 1 and boring cutter sheet 11 attached to it by boring bar axle 33 together rotates, make boring cutter sheet 11 do radially to pass by moving vertically downward of boring bar axle 33 simultaneously, thereby realized rotating in a circumferential direction and radial feed of inside groove processing.
As shown in Figure 2, the utility model boring cutter combination block 1 comprises boring cutter sheet 11, blade folder 12, cutter holder flange 14, boring cutter seat 18 and push rod 15 etc., described boring cutter seat 18 is fixed on the boring bar cover 32, push rod 15 places in this boring cutter seat 18, one end is the semicircle sphere, the insertion boring bar overlaps in the jack of offering on 32 and can touch mutually with boring bar axle 33, the other end is processed with a shaft shoulder, touch mutually with cutter holder flange 14, cutter holder flange 14 is fastening with blade folder 12 usefulness screws, on the blade folder 12 boring cutter sheet 11 is housed, boring cutter sheet 11 places blade to press from both sides 12 locating slots, be welded in one with copper arc welding electrode again, when changing blade, moltenly snap seam and get final product.On the blade folder 2 cover plate 16 is housed, is fixed on the boring cutter seat 18, adopt the gap to be slidingly matched between the two, to guarantee the correct guidance of boring cutter sheet 11 when radial feed and the withdrawing.The width dimensions of cutting inside groove is controlled by the width of blade, guarantees when cutting blade.
Press from both sides 12 bottoms at blade, be equipped with and adjust pad 13, between blade folder 12 and cutter holder flange 14, consider the length and the wearing and tearing of boring cutter sheet 11, in certain scope, can be by increasing or reduce the quantity of adjusting pad 13, control the radial depth of boring cutter sheet 11 incision dead eyes, to satisfy the requirement of inside groove depth dimensions, when 11 wearing and tearing of boring cutter sheet are too short, replaceable new blade.Between cover plate 16 and cutter holder flange 14, also be provided with elastic component 17, be used for ejection cutter holder flange 14, push rod 15, drive boring cutter sheet 11 and reset.
As shown in the figure, the utility model boring bar axle 33 afterbodys are the circular cone with certain angle with the partial design that push rod 15 touches mutually, when drill press spindle and boring bar axle 33 are done vertical feed downwards, boring bar axle 33 afterbody cone ejection push rods 15 heads, force cutter holder flange 14 extruding elastic components 17, drive blade folder 12, boring cutter sheet 11 to left movement, make radial feed.
During original state, boring bar axle 33 does not contact push rod 15, and elastic component 17 ejection cutter holder flanges 14 are against boring cutter seat 18 inner faces to the right, and boring cutter sheet 11 is inwardly shunk, and is convenient to sectional fixture and makes blade not injure workpiece 5 dead eyes.When the boring inside groove, boring bar axle 33 tail cone ejection push rods 15 make the 11 slow feeds of boring cutter sheet, realize cutting.When boring bar axle 33 continues when downward, when circular cone entered column part contact push rod 15, the depth of cut be a maximum, and this depth of cut is the feed distance of boring cutter sheet 11.After inside groove machined, boring bar axle 33 withdrawed from, and elastic component 17 can eject push rod 15 by cutter holder flange 14 automatically resets it, and meanwhile, boring cutter sheet 11 also withdraws from inside groove, is contracted to original position.
As shown in Figure 1, the utility model positioning component 2 comprises positioning sleeve 24, bearing 29, backing plate 21 etc., described positioning sleeve 24 tightly is placed on the boring bar cover 32, its outer round surface is equipped with bearing 29, this bearing is the separate type taper roll bearing, the bottom, outer ring is loaded on the bearing block 31 location end faces that are fixed on the backing plate 21, bearing baffle 30 is housed on the top, baffle plate 30 is by seam location, bearing block 31 upper end, fixing by the depression bar 23 that a briquetting 22 and an end are threaded onto on the backing plate 21,21 on backing plate is fastening by screw and workpiece 5.On boring bar axle 33, also be with pressing plate 27, the depression bar 26 that the bottom is fixed on positioning sleeve 24 is housed on this pressing plate 27, spring 28 is loaded between pressing plate 27 and the positioning sleeve 24, is placed on the depression bar 26.Like this, when boring bar axle 33 is done feed motion downwards, pass to 24 1 downward axial forces of positioning sleeve by pressing plate 27 and spring 28, taper roll bearing 29 Internal and external cycles are closed all the time in one, like this, anchor clamps move more steady reliably when rotary cutting, and the inside groove that processes with abundant assurance reaches the drawing quality requirement.
In the actual practicality, consider that asymmetric cutting can make the cutting force list inclined to one side, thereby make boring bar axle 33 and boring bar overlap 32 beats, cause rotatablely move not steady, the utility model is welded with radial support seat 41 on boring bar cover 32, on this supporting seat, radial support 4 is housed, to guarantee the stationarity of motion with screw.For reducing the wearing and tearing of 4 pairs of dead eyes of radial support, the material of radial support 4 can be selected brass alloys for use, supports wearing and tearing back fast changeable.
For overcoming heating and the dry grinding of boring cutter sheet 11 in the boring process, to strengthen the lubricated of blade and to prolong its service life, as shown in Figure 3, the utility model is offered a clear opening on positioning sleeve 24, oil fuel tube 52 1 ends pass through this through hole and place boring cutter sheet 11 tops, the other end is positioned on the pressing plate 27 by oiling base 51, adopt matched in clearance between oiling base 51 and the pressing plate 27, with moving down of not overslaugh pressing plate 27, lubricating oil can be injected on the boring cutter sheet 11 by this pipe, boring cutter sheet 11 is cooled off and lubricates.Slower because of inside groove boring speed, lubricating oil only need splash at interval and can meet the demands.
