Abstract
The utility model relates to a single-blade fine adjusting precise boring cutter used for machining holes, comprising a cutter body and a cutter holder. The precise boring cutter is characterized in that a sliding toolholder bit is arranged inside the cutter body; a fine adjusting nut is fixed on the sliding toolholder bit; a fine adjusting screw rod is connected with the cutter body through a stop nut and a limiting bush. The fine adjusting nut and the fine adjusting screw rod constitutes a pair of thread transmission mechanisms; the cutter holder is disposed at the end of the sliding toolholder bit and is locked and fixed by a locking bolt; the blade is disposed at the end of the cutter holder. A dial is arranged at one end of the fine adjusting screw rod and a butterfly spring is arranged between the stop nut and the dial. Compared with the fine adjusting precise boring cutters in existence, the fine adjusting precise boring cutter of the utility model is compact in structure and is convenient to adjust due to the thread transmission mechanisms; the diameter of the hole bored with the boring cutter ranges from 2mm to 150mm; the dial is wide in adjustment range and high in adjustment accuracy with a precision of 0.01mm each time the dial turns one graduation.
Description
Technical field
The utility model belongs to the metal cutting technology field, is specifically related to the processing of a kind of hole and finely tunes fine boring cutter with single-blade.
Background technology
The fine setting fine boring cutter be a kind of have a micromatic setting accurately machined cutter is carried out in the hole.Along with the fast development of industrial technology, people have higher requirement to the machining accuracy in hole, and therefore the fine setting fine boring cutter is applied in the production practices more and more.The fine setting fine boring cutter majority of domestic present production all is ready-made fine setting right boring unit simply to be installed on the cutter hub 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.
The utility model content
The purpose of this utility model is: provide a kind of in the right boring process cutter structure compactness, adjusting range is big, precision is high, the easy single-blade of method of adjustment fine setting fine boring cutter.
For achieving the above object, the technical scheme that adopts is: single-blade fine setting fine boring cutter, comprise cutter hub and knife bar, it is characterized in that: described cutter hub is built-in with the slip cutter holder, is fixed with fine-tuning nut on the described slip cutter holder, and the fine setting screw rod is 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 is locked by lock-screw, and described blade places the end of described knife bar.
One end of described fine setting screw rod is provided with dial, between dial and the described stop nut butterfly spring is installed.
Described knife bar also can be fixedlyed connected with described slip cutter holder from the end face of cutter hub.
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 2mm to φ 150mm, every rotation one lattice of dial, and precision is 0.01mm, adjusting range is big, adjusts the precision height.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a standard fine setting fine boring cutter structural representation (bore hole φ 20～φ 150mm);
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation (bore hole φ 2～φ 22mm) of small-bore fine setting fine boring cutter.
Among the figure, 1-cutter hub, 2-lock-screw, 3-slip cutter holder, 4-blade, 5-knife bar; The 6-fine-tuning nut, the spacing lining of 7-, the 8-stop nut, 9-finely tunes screw rod, 10-butterfly spring; 11-cutter holder lock-screw.
The specific embodiment
As depicted in figs. 1 and 2, single-blade standard fine setting fine boring cutter, comprise cutter hub 1 and knife bar 5, it is characterized in that: described cutter hub 1 is built-in with slip cutter holder 3, is fixed with fine-tuning nut 6 on the described slip cutter holder 3, and fine setting screw rod 9 is connected with described cutter hub 1 by stop nut 8, spacing lining 7, described fine-tuning nut 6 and described fine setting screw rod 9 thread transmission that partners, described slip cutter holder 3 ends are equipped with knife bar 5, and are locked by lock-screw 2, and described blade 4 places the end of described knife bar 5.
Between described dial that places described fine setting screw rod 9 ends and the described stop nut 8 butterfly spring 10 is installed.
Described knife bar 5 is fixedlyed connected with described slip cutter holder 3 from the end face of cutter hub 1.
Tool-bar for accurately boring 5 can be changed, and unclamps cutter head lock-screw 2, can change tool-bar for accurately boring 5, to satisfy the processing in the different holes that require of unlike material.When the dial on the turn fine setting screw rod 9, fine-tuning nut 6 will drive slip cutter holder 3 and slide in boring cutter body 1, realizes the adjustment of size.Butterfly spring 10 is installed between the dial and stop nut 8 of fine-tuning nut 5, produces a pretightning force, can prevent jumping of when adjusting dial, makes adjustment more accurate.During adjustment, unclamp cutter holder lock-screw 11 earlier, with the dial on the allen wrench turn fine setting screw rod 9, when rotating clockwise, size is big 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 size adjusting is good, tighten cutter holder lock-screw 11.
Fine setting fine boring cutter in small-bore shown in Figure 3, its micro-adjusting mechanism and method of adjustment and embodiment 1 are identical.Different is, its tool-bar for accurately boring 5 is that the end face from boring cutter body 1 stretches into and is installed on the slip cutter holder 3.Unclamp lock-screw 2, by changing tool-bar for accurately boring 5, it can the interior aperture of right boring diameter phi 2～φ 22mm scope.
