Description

For the boring bar of adjustable boring tool
Technical field
The utility model relates to a kind of boring cutter bar, specifically relates to a kind of boring bar for adjustable boring tool of improvement.
Background technology
Its clamping part of the boring bar that common boring machine uses is Morse taper shank, and a square hole is opened in boring bar front end, and knife bar is inserted in square hole, and knife bar is fixed by the screw of side, termination.During bore hole, according to bore size, loosen screw, slightly beat knife bar control knife bar and stretch, after reaching size, then tightening screw fixes knife bar.Circulate repeatedly with this, process the hole of required size.Use common boring bar bore hole to require very high to operating personnel's technical merit, be difficult to control because beat knife bar stroke, completely by the experience of operating personnel, and need repeatedly reciprocal.And traditional brazed shank tool blade needs frequent sharpening, therefore working (machining) efficiency is very low, and the size of machining hole is difficult to ensure, quality is unstable.Present new material is a lot, and the workpiece of some special materials utilizes traditional welding cutter, because blade material is limited, processes also very difficult.
The blade of the Novel adjustable boring tool that present Digit Control Machine Tool uses is mechanical clamped cutting blade, and blade easy accessibility, blade material is many, can meet various special material work pieces process.The turnover of Novel adjustable boring tool blade regulates precisely convenient, therefore working (machining) efficiency and machining accuracy high, and crudy is stablized.But Digit Control Machine Tool is equipped with the boring bar clamping part used now is special taper shank, and cannot be arranged on common boring machine and use, therefore the advantage of Novel adjustable boring tool cannot realize on common boring machine.
Utility model content
Technical problem to be solved in the utility model is by usual various adjustable boring tools used on Digit Control Machine Tool now, after to the improvement of knife bar, also can use on common boring machine, thus improves machining accuracy, ensures product quality.
The technical scheme that the utility model adopts for above-mentioned technical problem is, for the boring bar of adjustable boring tool, one end of its boring bar body is Morse taper shank, the other end opens a square hole, straight boring cutter is fixed with by screw in square hole, the termination that boring bar body is provided with square hole is provided with blind hole, boring bar body and the same axis of blind hole, the bar wall at the blind hole place of boring bar body is arranged with screw, adjustable boring tool frame is step cutting pattern shape, the small end external diameter of adjustable boring tool frame is matched with the blind hole internal diameter of boring bar body and is fixedly connected with by the screw in screw, the large end of adjustable boring tool frame is provided with adjustable boring tool.
The utility model advantage is by improving common boring bar, makes novel boring bar be used for common boring machine, and its inner hole precision processed is high, steady quality, and versatility is good, and improve after boring bar easy to operate, working (machining) efficiency is high.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1. boring bar body, 2. screw, 3. straight boring cutter, 4. adjustable boring tool frame, 5. adjustable boring tool.
Detailed description of the invention
Now the utility model is described in further detail by reference to the accompanying drawings, see Fig. 1 and Fig. 2, for the boring bar of adjustable boring tool, one end of its boring bar body 1 is Morse taper shank, the other end opens a square hole, straight boring cutter 3 is fixed with by screw 2 in square hole, the termination that boring bar body 1 is provided with square hole is provided with blind hole, boring bar body 1 and the same axis of blind hole, the bar wall at the blind hole place of boring bar body 1 is arranged with screw, adjustable boring tool frame 4 is step cutting pattern shape, the small end external diameter of adjustable boring tool frame 4 is matched with the blind hole internal diameter of boring bar body 1 and is fixedly connected with by the screw 2 in screw, the large end of adjustable boring tool frame 4 is provided with adjustable boring tool 5.
The boring bar that the utility model is used for adjustable boring tool is the hole and the screw that increase an Installation of New Type adjustable boring tool frame 4 in common boring bar termination, square hole on common boring bar is moved backward, side changed into by the screw 2 of boring bar body 1, and all the other are with common boring bar the same (as depicted in figs. 1 and 2).During processing work bore hole, first adjustable boring tool frame 4 and adjustable boring tool 5 can be taken off, ordinary straight boring cutter 3 is loaded in the square hole of boring bar body 1, machine away most of surplus of workpiece hole, then load onto adjustable boring tool frame 4 and adjustable boring tool 5 in boring bar body 1 termination, fast workpiece hole is worked into drawing dimensional requirement.Variously novelly toolsetting installation dimension can be generally uniform sizes, therefore boring bar of the present utility model can fill various Novel adjustable boring tool, and versatility is good.Boring bar of the present utility model makes the advantage of Novel adjustable boring tool be played on common boring machine.
