Description
(1) technical field
The utility model belongs to boring machine parts, particularly a kind of fast tool changing boring bar, and the bore hole that is mainly used in various boring machines and machining center is processed.
(2) background technology
Common boring bar is a monoblock type, and afterbody is the instrument taper shank, inserts in the lathe spindle hole, and the horizontal evolution groove of head inserts cutter head, and is fastening with screw, worked by the main shaft driven rotary.According to varying in size of processed bore dia, need the frequent different-diameter boring bar of changing.Like this, on the one hand because the weight of major diameter boring bar is heavier, the frequent replacing brought heavy manual labor to the operative employee, reduces efficiency, and on the other hand, each boring bar all has the instrument taper shank, and cost of manufacture is higher, has increased processing cost.Common boring bar tool setting, generally all be that cutter head installs, pre-boring once in workpiece, with the pre-once bore size of gage measuring, the operator manually adjusts cutter head again according to the size that differs again, pre-again boring, measurement, adjustment, circulation repeatedly, up to adjust to meet the drawing size till, like this operation waste time and energy.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, the fast tool changing boring bar of provide a kind of and change conveniently, tool setting is convenient, efficiency is high, cost is low.
The utility model is achieved by the following technical solution:
Fast tool changing boring bar of the present utility model, afterbody is useful on instrument taper shank and the locating groove that inserts lathe, its special character is: this fast tool changing boring bar is made up of by being threaded two sections of front and back, leading portion is the quick change tool rest, back segment is the quick change cutter hub, instrument taper shank and locating groove are positioned on the quick change cutter hub, on the quick change tool rest boring cutter are installed, and quick change tool rest middle part is provided with the dismounting hole perpendicular to the lathe rotation.
Fast tool changing boring bar of the present utility model, quick change tool rest front end is opened a rectangular channel, rectangular channel is provided with the tool setting locating piece in the middle of the bottom, the rectangular channel both sides are provided with the square boring cutter jack of two perpendicular alignmnet tool setting locating pieces, be staggeredly arranged before and after two boring cutter jacks, quick change tool rest front end face is drilled with the fixedly clamp screw keyhole of boring cutter.
Fast tool changing boring bar of the present utility model is external thread rod on the quick change tool rest, is internal thread hole on the quick change cutter hub, and the internal thread hole porch is provided with straight mouthful of location, and the external thread rod root is provided with and locatees straight mouthful of corresponding positioning step.
Fast tool changing boring bar of the present utility model, two sections screw thread is left-handed trapezoidal thread before and after connecting.
The beneficial effects of the utility model are that replacing is convenient, tool setting is convenient, efficiency is high, cost is low, and is specific as follows:
1, quick change cutter hub can be equipped with the quick change tool rest of many different-diameters, only need change the quick change tool rest when processing different aperture, the quick change tool rest relies on left-handed trapezoidal thread to be connected with cutter hub, firmly turn clockwise and to pull down in the dismounting hole with circular pricker rod insertion quick change tool rest during replacing, do not need any specific purpose tool.Quick change tool rest volume is little in light weight, and it is convenient to change, and it is low to make processing cost, has also reduced cost when reducing labour intensity.
2, a quick change tool rest can be installed two boring cutters simultaneously, and the one in front and one in back symmetrical interlaced arrangement of boring cutter differs 2mm between last boring cutter and back one boring cutter, is equivalent to the original bite that once is equipped with is divided into twice processing simultaneously, alleviate tool wear, improved working (machining) efficiency.Because cutter head symmetry interlaced arrangement makes to alleviate vibrations by the symmetrically and evenly stressed of machine tool chief axis, has protected lathe.
3, the quick change tool rest is provided with the tool setting locating piece, and tool setting is accurately convenient.Use fast tool changing boring bar, only need once pre-boring during tool setting, calculate the size that the relative tool setting locating piece of boring cutter should be adjusted, utilize the clearance gauge adjustment, once get final product accurate tool setting according to measurement size, time saving and energy saving.
(4) description of drawings
Fig. 1 is an overall schematic of the present utility model, and schematic diagram cuts open in schematic perspective view, office that Fig. 2, Fig. 3 are respectively the quick change cutter hub, and schematic diagram cuts open in schematic perspective view, office that Fig. 4, Fig. 5 are respectively the quick change tool rest.
Among the figure, 1 quick change cutter hub, 2 quick change tool rests, 3 instrument taper shanks, 4 locating grooves, 5 internal thread holes, straight mouthful of 6 location, 7 tool setting locating pieces, 8 dismounting holes, 9 clamp screw keyholes, 10 boring cutter jacks, 11 positioning steps, 12 left-handed trapezoidal threads, 13 rectangular channels.
