Abstract
The utility model relates to a cylinderical floating boring cutter used to process the inner holes on the lathe, the boring mill and the driller, composed of a left boring bar (1), a boring head (2), a fine tuning nut (3), a screw (4), a cylinderical key (5), a right boring bar (6), an indexable triangle blade (7), a pressboard (8) and a screw (9). The utility model is characterized in that the boring cutter bar is a cylinder. Compared with the prior art (cuboid floating boring cutter), the inner hole processed by the utility model has high precision and high surface roughness, and the adjustment of the processing dimension is convenient and accurate.
Description
The utility model is a kind of cylindrical float boring cutter of processing endoporus, is used for lathe, boring machine, upright drill and deep hole drilling machine, is particularly suitable for the usefulness of fine finishining endoporus.
Existing floating boring tool is a cuboid.
Existing cuboid floating boring tool.A, its boring cutter bar and boring head hole all are the square-sections, make difficulty, and precision is difficult to guarantee, thereby influences the quality of machining hole; The sharpening angle and the cutting angle of b, its two terminal knife edge are inconsistent, cause the surface roughness of machining hole low; The size adjusting inconvenience of c, machining hole, inaccuracy.The purpose of this utility model is: a kind of cylindrical float boring cutter that can solve above-mentioned three problems preferably is provided.
Cylindrical float boring cutter (see figure 1) is made up of left boring bar 1, boring head 2, fine-tuning nut 3, screw 4, round key 5, right boring bar 6, indexable triangular blade 7, pressing plate 8 and screw 9, it is characterized in that boring bar is the garden cylindricality.The left boring bar 1 that fine-tuning nut 3 is housed is packed in the hole of right boring bar 6, tighten screw 4, left boring bar 1 and right boring bar 6 are tightened up, round key 5 plays a part to lead and prevents that boring bar from rotating, load onto blade 7, and blade 7 is compressed, this floating boring tool body that assembles is packed in the hole of boring head 2 with pressing plate 8 and screw 9, then it is loaded on the knife bar of lathe, boring machine, upright drill or deep hole drilling machine, just can carries out the processing of endoporus workpiece.
The contrast of the utility model and prior art:
1. the boring cutter bar and the boring head hole of existing floating boring tool all are the square-sections, and the accuracy of manufacture (quality of fit in boring cutter bar and boring head hole and mutual alignment precision) is difficult to guarantee, thereby influences the quality of machining hole.And floating boring tool of the present utility model, its boring cutter bar and boring head hole all are circular, the accuracy of manufacture guarantees easily, so the quality of machining hole is higher.
2. two blades of existing floating boring tool rectangle cutter hub all are higher than cutter side partly, cause sharpening angle and cutting angle inconsistent.φ 130mm boring cutter for example, become γ=0 ° during γ during sharpening=10 ° α=3 ° cutting, α=6 °, in order not influence crudy, improve machining condition and with anterior angle γ mill greatly to 25 °, α=-4 ° such intensity that not only influences blade, and because of the unreasonable frequent knife of cutting angle, all knife vestiges of one intermittently appear; And owing to there is squeezing action, make the chip removal difficulty, produce chip.Cause the surface roughness of machining hole low, have only
About.Cylinder floating boring tool of the present utility model, two blade all are levels, all pass through the center line of left boring bar 1 and right boring bar 6, and like this, sharpening angle is consistent with cutting angle, stable cutting, and the surface roughness of machining hole is higher.
3. it is to see Fig. 2 by adjustment screw 4(that existing cuboid floating boring tool is adjusted processing dimension) toward sinciput cutter hub 2, adjusting range is little, inaccurate, and because the gathering sill size of cutter hub 1 and cutter hub 2 is inaccurate, two-edged is not parallel after adjusting size, it is parallel, time-consuming to need to be trimmed to two-edged by the cutter mill, and effect is bad.Cylindrical float boring cutter of the present utility model is provided with fine-tuning nut, has scale (every lattice 0.01mm), and the adjustment processing dimension is simple, accurate and adjusting range is bigger.For example: a bit of back of first heavy boring withdrawing, if the size of measured hole than requiring the also little 0.05mm of size, is unclamped screw 4(and is seen Fig. 1), fine-tuning nut is turned over 5 lattice, tighten behind the screw 4 bore hole again, just can be worked into desired size.
Most preferred embodiment: process cylinder body with horizontal lathe.Aperture φ 280+0.1mm, hole depth 880mm, surface roughness
The floating boring tool that assembles is a bit of to cylinder hole elder generation heavy boring, withdraw from cutter, measure the actual size in cylinder hole, 2(sees Fig. 1 from boring head) the taking-up floating boring tool, unclamp screw 4,, tighten screw 4 backs bore hole processing is carried out in the cylinder hole by the lattice number (every lattice 0.01mm) of desired size rotation fine-tuning nut, reaching hole dimension is φ 280+0.04mm, and surface roughness reaches
, reach through after the honing
Claims (4)
1, a kind of lathe, boring machine and drilling machine are processed the floating boring tool that endoporus is used,
Be characterised in that boring bar is a circular cross-section, form, be particularly suitable for the usefulness of fine finishining endoporus by left boring bar 1, fine-tuning nut 3, garden post key 5, right boring bar 6, indexable triangular blade 7 etc.
2, Cylinder floating boring tool according to claim 1, it is characterized in that fine-tuning nut 3 is to be contained on the left boring bar 1, with the left boring bar 1 that fine-tuning nut 3 the is housed right boring bar 6 of packing into, when screw 4 is in releasing orientation, can rotate fine-tuning nut 3, to adjust the axial dimension (being the size of institute's machining hole) of floating boring tool.
3, cylindrical float boring cutter according to claim 1 is characterized in that adopting indexable triangular blade, and two blades are levels, all passes through the center line of left boring bar 1 and right boring bar 6.
4, Cylinder floating boring tool according to claim 1 is characterized in that being equipped with at least two garden post keys 5, for guiding with prevent the usefulness of boring bar rotation.
