The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 2, the utility model is a kind of drilling machine with the flat cutter of the anti-ream of aperture, mainly designs based on the basis of existing cutter.The utility model mainly comprises knife bar 31, countersink cutter hub 32 and block 33 compositions.In the design of knife bar 31 (as shown in Figure 3 and Figure 4), the knife bar upper part 311 that links to each other with drill press spindle can be designed to the large diameter cylinder type knife bar that matches with main shaft, 313 both sides, knife bar bottom then can be made into by the mode of lathe turning and cut oblateness, and for the ease of countersink cutter hub 32 and block 33 are installed on the knife bar 31, knife bar the latter half 312 of a small diameter cylinders shape also need be set for this reason, and knife bar bottom 313 and knife bar the first half 311 be fixed together by knife bar the latter half 312; When the design of countersink cutter hub 32 (as shown in Figure 5), offer a through hole that is used to install knife bar 31 along the axis at shaft core position place, the diameter dimension size of the size of this through hole and knife bar 31 matches, and being provided with two and cooperating the groove grooves 322 that link to each other with block 33 projections 331 in the bottom of cutter hub 32 symmetry; And in the design of block 33 (as Fig. 6 and shown in Figure 7), axle line position place also designs one and is used for the through hole that links to each other with knife bar 31 therein, the upper end is provided with two and is used for the projection 331 that matches with groove groove 322, in the bottom of block 33, also symmetrical two dells 332 that are provided with and cut flat knife bar base section 313 matched in clearance.For this reason, in the utility model, countersink cutter hub 32 assigns into the latter half of knife bar 31, and the lower end of cutter hub 32 cooperates with block 33 and links to each other, and block 33 is buckled in the upper end of knife bar bottom 313 by dell 332.
When the utility model used, its method and operation principle were as follows: earlier with knife bar 31 upper end clampings on the rotated bed main shaft, press down the rotated bed main shaft, make knife bar 31 the latter halfs pass in the machining hole 1 that workpiece need process; Then the rotated bed main shaft do not rotate or the state of slow rotation under with countersink cutter hub 32 through knife bar 31 on, the downside that is connected countersink cutter hub 32 that link stopper 33 is cooperated again, make the outstanding projection 331 in block 33 upper ends embed in the groove 322 of countersink cutter hub, rotate countersink 32 and block 33 more simultaneously, the rotation direction reversed of their relative main shafts is turned an angle, at this moment cut 313 its positions, upper end, flat knife bar bottom and just can be entered in the dell 332 of block 33 by buckle, so countersink cutter hub 32 and block 33 just are fixed on the knife bar 31 firmly; Then just can start drilling machine and make drill press spindle begin to rotate, and pass through the method for the height and position of lifting drill press spindle, drive countersink cutter hub 32 and move upward, make the 321 pairs of workpiece machining holes in cutter head position 1 on the countersink cutter hub 32 carry out the flat processing of anti-ream.After finishing processing, close drilling machine, and press down drill press spindle, make countersink cutter head position 313 break away from working face, the rotated bed main shaft do not rotate or the state of slow rotation under, with hand with block 33 and countersink 32 forward rotation certain angles, thereby break being connected between countersink cutter hub 32 and block 33 and block 33 and the knife bar end portion 313 successively, countersink cutter hub 32 and block 33 can be removed from knife bar 31 easily; After countersink cutter hub 32 is disassembled, upwards mentions the rotated bed main shaft knife bar 31 is withdrawed from from workpiece machining hole 1.Repeat above-mentioned action, just can carry out the flat processing of anti-efficiently ream next workpiece machining hole.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
