Background technology
Boring machine is generally applied to the expansion processing of the prefabricated endoporus of part (particularly heavy parts), during its work, utilizes the rotation of boring bar and knife bar to drive coupled unsettled cutter to rotate, thus carrying out the expansion processing of the prefabricated endoporus to static part.Traditional boring machine can only process Cylinder inner bore, and the size in aperture needs operator that cutter is regulated accurately, and the technology of operator is required higher by it, and slightly mishap will result in scrapping of workpiece.
Certainly, in prior art, also some boring machine can process taper inner by the radial motion of regulating boring cutter, but its tapering size is the gear ratio by gear controls, or increase tapering slide rail on boring bar and make cutter move as gradient along slide rail to control.For being controlled the mode of tapering by the gear of gear ratio, if nonstandard taper inner in the course of processing, must coupling gear ratio again, and gear ratio can not be too small, otherwise, substantially cannot process too small gear than corresponding taper inner, it addition, adopt this processing mode, the supporting of its cutter belongs to cantilever support, cutter rigidity extreme difference, can only carry out small boring processing, and working (machining) efficiency is extremely low；And for by increasing tapering slide rail on boring bar and making cutter move as gradient along slide rail to control the mode of tapering, the deviation from circular from of the taper inner processed is bigger, have a strong impact on the quality of fit of taper inner and target axle, reduce the bearing capacity of part (particularly heavy parts), for this, after being processed by which, also need to by manually taper inner being carried out scraping, and ongoing painted cooperation, until the quality of fit of taper inner and target axle meets required precision, obviously, it need to put into substantial amounts of manpower, and operator's technical merit is had higher requirement.
Summary of the invention
It is an object of the invention to provide the boring cutter bar of a kind of numerical control borer, it can control the radial motion of boring cutter automatically, quickly and accurately, thus the endoporus of the requirement of different pore size and tapering can be processed.
The boring cutter bar of a kind of numerical control borer of the present invention, including the support body being fixed on boring bar, and for installing the tool rest of boring cutter, described tool rest is arranged in support body by guide rail with coordinating of slide block, and can slide along the radial direction of boring bar, the ball screw that tool rest slides can be driven along the radial direction of boring bar when rotation being installed also by bearing inside support body, and the gear assembly that ball screw rotates can be driven, described gear assembly includes the driven gear being loaded on ball screw, it is arranged on the driving gear in the steering spindle being arranged in parallel with ball screw and driven bevel pinion, and the driving bevel gear being connected with the power transmission shaft of servomotor, wherein, driven gear engages with driving gear, driving bevel gear and driven bevel pinion engagement, it is rotatable that steering spindle is arranged in support body by bearing, servomotor is then fixed on boring bar.
The boring cutter bar of a kind of numerical control borer of the present invention, including the support body being fixed on boring bar, and for installing the tool rest of boring cutter, described tool rest is arranged in support body by guide rail with coordinating of slide block, and can slide along the radial direction of boring bar, the ball screw that tool rest slides can be driven along the radial direction of boring bar when rotation being installed also by bearing inside support body, and the gear assembly that ball screw rotates can be driven, described gear assembly includes the driven bevel pinion being loaded on ball screw, it is arranged on and the driven gear in the vertically arranged rotating shaft of ball screw and driving bevel gear, and the driving gear being connected with the power transmission shaft of servomotor, wherein, driven gear engages with driving gear, driving bevel gear and driven bevel pinion engagement, it is rotatable that rotating shaft is arranged in support body by bearing, servomotor is then fixed on the outer wall of support body.
Tool rest be can be slidably mounted in support body by guide rail with coordinating of slide block by the present invention, pass through servomotor, the cooperation of gear assembly and ball screw drives tool rest to slide along the radial direction of boring bar, and owing to servomotor and ball screw are respectively provided with significantly high positioning precision, so, process in the process of inner bore of part in boring, servomotor can quickly make corresponding action after receiving servosystem instruction set in advance, and drive gear assemblies drives ball screw to rotate, thus driving the boring cutter on tool rest rapidly and accurately to move radially corresponding displacement along boring bar, finally make the endoporus that the boring cutter boring on part rotated with boring bar goes out different pore size and tapering requires.
