Overall structure about the hole processing device of tellite is described in front by Figure 15, and still, repeat specification is omitted, and by Fig. 1 (1), (2)～Fig. 3 specifically describes the axle sleeve that is installed on the presser feet bottom.
At first, Fig. 1 (1), an example of (2) expression axle sleeve shape, this Fig. 1 (1) is a longitudinal sectional view, Fig. 1 (2) is the cutaway view of the A-A line among Fig. 1 (1).In Fig. 1 (1), among the axle sleeve 4A shown in (2), arrive inner a plurality of (in the present embodiment, being 8) the 1st gas passage 41 that forms from the side, by the 1st gas passage 41, the air outside of aforesaid presser feet 3 is attracted to inside, produce vortex and reflux.In addition, the machined object side in the 1st gas passage 41, a plurality of (being 4 in the present embodiment) the 2nd gas passage 42A is as from the outside, the bottom surface of axle sleeve 4A, extends to inboard groove and forms.The 2nd gas passage 42A by this groove shape attracts air outside, and the vortex that produces the air that arrives chisel edge portion refluxes.
In addition, Fig. 2 (1), another example of (2) expression axle sleeve shape, Fig. 2 (1) is a longitudinal sectional view, Fig. 2 (2) is the cutaway view along the B-B line of Fig. 2 (1).In Fig. 2 (1), identical among the axle sleeve 4B shown in (2) with above-mentioned axle sleeve 4A, arrive inner a plurality of (in the present embodiment, being 8) the 1st gas passage 41 that forms from the side, by the 1st gas passage 41, air outside is attracted to the inner vortex that produces refluxes.In addition, the machined object side in the 1st gas passage 41, a plurality of (in the present embodiment, being 4) the 2nd gas passage 42B extends to inboard through hole as the outside, side from axle sleeve 4A and forms.By the 2nd gas passage 42B of this through hole shape, attract air outside, the vortex that produces the air that arrives chisel edge portion refluxes.
In Fig. 1 (1), (2) and Fig. 2 (1), among axle sleeve 4A, the 4B shown in (2), compare with the sectional area summation of the 1st gas passage 41, the 2nd gas passage 42A or 42B sectional area summation are less, and the 2nd gas passage 42A, 42B are formed at the position near the leading section of drill bit 5.
Fig. 3 is illustrated in the structure that axle sleeve 4B is installed in the bottom of above-mentioned presser feet 3, because the sectional area summation of the 2nd gas passage 42B is less, so accelerate from the flow velocity of the 2nd gas passage 42B leaked-in air, forms vortex backflow at a high speed around the leading section of drill bit 5.The vortex of this high speed refluxes can prevent that smear metal is wound in the situation on the drill bit 5, and by heat insulation expansion, air stream is cooled off, and with good efficiency drill bit 5 is cooled off.
On the other hand, can form bigger vortex in the outside that the vortex that forms by above-mentioned the 2nd gas passage 42B refluxes from the 1st gas passage 41 leaked-in airs refluxes, reflux by the vortex that forms by the 1st gas passage 41, carry out the discharge of smear metal from tap 8 with good efficiency.In addition, by from the 2nd gas passage 42B leaked-in air, form the occasion of superfluous decompression only, the 1st gas passage 41 has the air inflow that this situation is compensated simultaneously and adjusts function.
In order to reflux according to the vortex that is formed near the high speed the above-mentioned drill bit 5, the mode that 2 vortexs that reflux with the vortex that is formed at its outside reflux realizes the inflow of air, best, with regard to the 1st gas passage 41 of axle sleeve 4B side and the sectional area ratio of the 2nd gas passage 42B, the sectional area total value of the 2nd gas passage 42B of a plurality of openings be a plurality of openings the 1st gas passage 41 the cross section total value 10～50%.
In addition, among Fig. 3, to adopting Fig. 2 (1), the occasion of the 2nd gas passage 42B of the through hole shape shown in (2) is described, and still, is adopting Fig. 1 (1) equally, and the occasion of the 2nd gas passage 42A of the groove shape shown in (2) has identical action effect.In addition, Fig. 1 (1), (2) and Fig. 2 (1), the quantity that is provided with that quantity and the 2nd gas passage 42A, 42B are set of the 1st gas passage 41 shown in (2) is not limited thereto, and for can be in both scopes of sectional area ratio, forms the quantity that is provided with that vortex refluxes and gets final product.
In addition, also have because of the material as the tellite of workpiece 1, smear metal is twined easily when boring, must form the situation of vortex backflow more at a high speed near drill bit.Also can be at every kind of material of tellite, specify the total sectional area ratio of the 1st gas passage 41 and the 2nd gas passage 42A or 42B,, adopt the axle sleeve 4 of appointment at every kind of material of tellite, increase the problem of keeping and cost aspect but have the parts stockpile number.Therefore,, the mechanism of blocking corresponding opening with size arbitrarily is set, then can prepare multiple axle sleeve, obtain at every kind of material of tellite and different sectional area ratios if in advance to set the diameter of the 1st gas passage 41 largely.
