Abstract
The utility model discloses a vertical compression type single-blade fine adjustment fine boring cutter, belongs to the technical field of metal cutting boring cutters, and aims at achieving the effects that the vertical compression type single-blade fine adjustment fine boring cutter is compact in structure, can be used for forward fine boring and reverse fine boring and can improve the alignment accuracy of an existing boring cutter. The vertical compression type single-blade fine adjustment fine boring cutter is characterized in that a sliding cutter holder is arranged in a cutter body, a fine adjustment nut is fixedly arranged on the sliding cutter holder, a fine adjustment screw rod is connected with the cutter body through a limiting nut and a limiting bush, the fine adjustment nut and the fine adjustment screw rod form a threaded transmission mechanism, a cutter pole is arranged on the end portion of the sliding cutter holder and fixedly locked through a locking screw, and a cutter head is arranged on the end portion of the cutter pole. A dial is arranged on the end portion of the fine adjustment screw rod, and a belleville spring is arranged between the dial and the limiting nut. The vertical compression type single-blade fine adjustment fine boring cutter is compact in structure, convenient to adjust due to the fact that the threaded transmission mechanism composed of the fine adjustment nut and the fine adjustment screw rod is used, wide in adjustable range and high in accuracy due to the fact that the diameter accuracy is 0.01 millimeter every time the dial rotates to one mark. The cutter pole can be installed in a forward mode or a reverse mode according to needs, and after the locking screw is locked, the forward fine boring or the reverse fine boring can be realized easily.
Description
Technical field
The utility model belongs to the metal-cutting machine tool technical field, is specifically related to a kind of direct press type single-blade fine setting fine boring cutter of existing hole being processed usefulness.
Background technology
Boring cutter is a kind of of cutting tool for boring, and boring cutter can use at boring machine, lathe or milling machine, is used for roughing, semifinishing or fine finishining are carried out in existing hole, and the most frequently used occasion is exactly the processing of boring cutter endoporus, reaming etc.The shape of single-blade boring cutter cutting tip is similar to lathe tool.In order to make the hole obtain high dimensional accuracy, fine finishining needs to adjust exactly with the size of boring cutter.Along with the fast development of industrial technology, the fine setting fine boring cutter is applied in the production practices more and more.But the fine setting fine boring cutter majority of domestic production at present all is ready-made fine setting right boring unit to be installed on the cutter hub simply make, this fine boring cutter is owing to be subjected to the restriction of right boring unit, many limitation are arranged, as can not the boring aperture, adjusting range is little, and it is not high to adjust precision yet, and every adjustment one lattice are 0.02mm.Obvious this fine setting fine boring cutter can not satisfy people to the higher requirement of the machining accuracy proposition in hole.
Summary of the invention
The purpose of this utility model is: provide a kind of in the right boring process cutter structure compactness, adjusting range is big, can positive and negative right boring, precision height, the direct press type single-blade fine setting fine boring cutter that method of adjustment is easy.
For achieving the above object, the technical scheme that adopts is: direct press type single-blade fine setting fine boring cutter, comprise cutter hub, cutter head, knife bar, it is characterized in that: described cutter hub is built-in with the slip cutter holder, be set with fine-tuning nut on the described slip cutter holder, the fine setting screw rod is fixedlyed connected with described cutter hub by stop nut, spacing lining, described fine-tuning nut and the described fine setting screw rod thread transmission that partners, described slip cutter holder end is equipped with knife bar, and be locked by lock-screw, described cutter head places the end of described knife bar.
The end of described fine setting screw rod is provided with dial.
Be provided with butterfly spring between described dial and the described stop nut.
Compare with existing fine setting fine boring cutter, the utility model compact conformation adopts thread transmission easy to adjust, and the bore hole scope can be from φ 20mm to φ 212mm, every rotation one lattice of dial, and the diameter precision is 0.01mm, adjusting range is big, adjusts the precision height.Behind the anti-dress of tool rest, can easily realize anti-right boring processing, the anti-right boring range of work can be from φ 30mm to φ 212mm, and precision is consistent with positive boring, must be rotated counterclockwise but add the man-hour cutter, and via diameter D satisfied " D 〉=(Dc+D1)/2+1 ".
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is direct press type single-blade fine setting fine boring cutter structural representation (bore hole φ 20～φ 212 mm);
Fig. 2 is that the P of Fig. 1 is to view;
Fig. 3 is fine setting fine boring cutter anti-right boring processing structure schematic diagram (bore hole φ 30～φ 212 mm).
Among the figure, the 1-cutter hub, the 2-lock-screw, the 3-knife bar, the 4-cutter head, 5-slip cutter holder, the 6-fine-tuning nut, the 7-stop nut, the spacing lining of 8-, the 9-butterfly spring, 10-finely tunes screw rod, 11-cutter holder lock-screw, 12-boring cutter cylindrical handle interface.
The specific embodiment
The structural representation of direct press type single-blade fine setting fine boring cutter is illustrated in Fig. 1 and Fig. 2, as seen from the figure, direct press type single-blade fine setting fine boring cutter, comprise cutter hub 1, cutter head 4, knife bar 3, it is characterized in that: described cutter hub 1 is built-in with slip cutter holder 5, be set with fine-tuning nut 6 on the described slip cutter holder 5, fine setting screw rod 10 is by stop nut 7, spacing lining 8 is fixedlyed connected with described cutter hub 1, described fine-tuning nut 6 and described fine setting screw rod 10 thread transmission that partners, described slip cutter holder 5 ends are equipped with knife bar 3, and be locked by lock-screw 2, described cutter head 4 places the end of described knife bar 3.
The end of described fine setting screw rod 10 is provided with dial.
Be provided with butterfly spring 9 between described dial and the described stop nut 7.
Among Fig. 2, boring cutter cylindrical handle interface 12 is used for being connected with handle of a knife, with the various processing request of rapid correspondence.
Can carry out anti-boring (shown in Figure 3) after tool-bar for accurately boring 3 tunes are installed, unclamp cutter head lock-screw 2, can reverse end for end to tool-bar for accurately boring 3, make cutter can carry out anti-bore hole.
Embodiment 1: the positive boring of cutter (diagram 1-2).
When the dial on the turn fine setting screw rod 10, fine-tuning nut 6 will drive slip cutter holder 5 and slide in boring cutter body 1, realizes the inching of processing dimension.Butterfly spring 9 is installed between the dial and stop nut 7 of fine setting screw rod 10, produces a pretightning force, can prevent from making adjustment more accurate when adjustment the jumping of dial.During adjustment, unclamp cutter holder lock-screw 11 earlier, with the dial on the allen wrench turn fine setting screw rod 10, when rotating clockwise, it is big that size becomes then, when counterclockwise rotates, and size decreases.Every adjustment one lattice on dial, point of a knife moves 0.005mm, and diametric(al) changes 0.01mm.After adjusted size is good, tighten cutter holder lock-screw 11(Fig. 2).
Embodiment 2: the anti-boring of cutter (Fig. 3).
Fine setting fine boring cutter shown in Figure 3, its micro-adjusting mechanism and method of adjustment and embodiment 1 are identical.Different is, unclamp lock-screw 2, knife bar 3 is instead adorned, locking lock-screw 2, can easily realize anti-right boring processing, precision is with just boring is consistent, must be rotated counterclockwise but add the man-hour cutter, and via diameter D satisfies " D 〉=(Dc+D1)/2+1 ", its hole in can anti-right boring diameter phi 30mm to φ 212mm scope.
