The boring cutter fixing device comprises a boring cutter shaft, a boring cutter rack and a boring cutter, wherein the boring cutter is fixed on the boring cutter rack, and the boring cutter rack is mounted on the boring cutter shaft. The boring cutter fixing device is characterized in that a fine adjustment device comprising an adjusting bolt and a nut is arranged on the boring cutter rack, an adjusting hole is formed on the boring cutter rack, the nut is fixed above the adjusting hole of the boring cutter rack, the adjusting bolt is inserted into the adjusting hole and is connected with the screw threads, when in use, a cutter shaft support is connected with the boring cutter shaft, the boring cutter axial line on the boring cutter rack is adjusted to coincide with the axial line of the boring cutter shaft through adjusting the bolt, the working efficiency is obviously improved, processing errors are reduced, and the boring cutter fixing device has the remarkable advantages of reasonable structure, convenience in use and the like.
Description
Technical field
The utility model relates to a kind of boring machine cutter, particularly a kind ofly can effectively improve machining accuracy, and is specially adapted to the boring cutter fixture of surfaces of revolution processing in the big workpiece.
Background technology
As everyone knows, occasions such as the endoporus processing in industrial processes, the application of boring machine cutter is very extensive.The boring machine cutter generally is made up of boring cutter axle, boring tool holder and boring cutter; Wherein boring cutter is fixed on the boring cutter axle through boring tool holder; In use through driving the rotation of boring cutter axle, make the boring cutter rotation on the boring cutter axle and move axially along the boring cutter axle, realize operations such as endoporus processing to workpiece to be processed.
The installation degree of accuracy of boring cutter also can have a strong impact on boring machine tool processes precision.Such as people knowledge, boring cutter is to be fixed on the boring cutter axle through knife rest, in order to guarantee the boring machine precision; The axis of boring cutter knife rest should overlap with the axis of boring cutter axle; Yet in the real production and processing, for example boring axle or knife rest exist defective, boring cutter fixing inaccurate etc. for various reasons, the axis of causing the axis of boring cutter knife rest to depart from the boring cutter axle; Cause machining accuracy to impact, so that concentricity, linearity, the awl compression of the endoporus of being processed can't reach requirement.
Summary of the invention
The utility model is to the shortcoming and defect that exists in the prior art, proposes a kind of rational in infrastructurely, easy to use, can effectively improve the boring machine precision, be particularly suitable for the boring cutter fixture of big workpiece endoporus processing.
The utility model can reach through following measure:
A kind of boring cutter fixture; Comprise boring cutter axle, boring tool holder and boring cutter, boring cutter is fixed on the knife rest, and boring tool holder is installed on the boring cutter axle; It is characterized in that boring tool holder is provided with the micro actuator of regulating the screw bolt and nut composition; Boring tool holder is provided with adjustment hole, and nut is fixed on boring tool holder adjustment hole top, and the adjusting bolt is inserted in the adjustment hole and with screw thread and is connected.
At least be provided with three adjustment holes on the utility model boring tool holder, the boring tool holder that adjustment hole is corresponding is provided with regulates the micro actuator that screw bolt and nut is formed.
When the utility model uses, be connected on cutter shaft support and the boring cutter axle, coincide through boring cutter axis and the boring cutter axis of regulating on the bolt adjusting boring tool holder; Can significantly improve operating efficiency; Reduce mismachining tolerance, find through practical implementation, feed is brought up to revolution 0.6mm-0.9mm by revolution .2mm-0.5mm before; Rotating speed is changeed by per minute before 20 brings up to per minute 40-50 commentaries on classics; Activity duration by before foreshortened to 4 days in 8 days, and before can effectively avoiding because the low situation that needs the abrasive machine polishing of the awl compression in hole, have advantage significantly such as rational in infrastructure, easy to use.
Description of drawings:
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of boring cutter fixture comprises boring cutter axle 1, boring tool holder 8 and boring cutter 11; Boring cutter 11 is fixed on the knife rest 8, and boring tool holder 8 is installed on the boring cutter axle 1, and the structure of above-mentioned kind of part and the mutual downlink connection relation between them are identical with prior art; This does not give unnecessary details, and the utility model is characterised in that boring tool holder 8 is provided with the micro actuator of regulating bolt 10 and nut 9 compositions, and boring tool holder 8 is provided with adjustment hole; Nut 9 is fixed on boring tool holder adjustment hole top, and adjusting bolt 10 is inserted in the adjustment hole and with screw thread 9 and is connected, and is provided with three adjustment holes on the utility model boring tool holder 8 at least; The boring tool holder that adjustment hole is corresponding is provided with regulates the micro actuator that bolt 10 and nut 9 are formed, and when the utility model uses, is connected on cutter shaft support and the boring cutter axle; Boring cutter axis and boring cutter axis through regulating on the bolt adjusting boring tool holder coincide, and can significantly improve operating efficiency, reduce mismachining tolerance; Find through practical implementation; Feed is brought up to revolution 0.6mm-0.9mm by revolution .2mm-0.5mm before, and rotating speed is changeed by per minute before 20 brings up to per minute 40-50 commentaries on classics, and the activity duration foreshortens to 4 days by before 8 days; And before can effectively avoiding because the low situation that needs the abrasive machine polishing of the awl compression in hole, have advantage significantly such as rational in infrastructure, easy to use.
