Abstract
Disclosed is an eccentric tool fine-adjustment mechanism. The mechanism comprises a toolbar, a locking nut, an elastic taper sleeve, an indicator, a set screw, a compression spring, a positioning steel ball and a tool holder. A detachable blade is mounted at one end of the toolbar, the other end of the toolbar is in close fit with a cylindrical inner hole of the tool holder, eccentricity is designed for the inner hole of the tool holder and a reference outer circle, a taper of the elastic taper sleeve is matched with an end taper hole of the tool holder, and an inner cylindrical h ole of the elastic taper sleeve is matched with the toolbar. The locking nut is connected on the tool holder through a thread, and the end face of an inner hole of the locking nut is in press fit with the large end face of the elastic taper sleeve. The radial positioning steel ball is arranged on the tool holder and is in press fit with an axial positioning groove in the toolbar, the toolbar rotates by a half cycle, and size from a tool nose to a reference center of the tool holder is changed correspondingly. When the locking nut is in press fit with the elastic taper sleeve, the toolbar is locked, and when the locking nut is loosened, the toolbar can be adjusted rotationally, so that an eccentric fine-adjustment function is realized.
Description
Technical field
The invention relates to a kind of centering type cutter fine adjustment mechanism, belongs to machine driving adjusting device, is mainly used in the tool position adjustment that hole in piece part adds man-hour.
Background technology
In the endoporus machining of part, after tool wear or processing dimension change and need to adjust the installation site of cutter, the micro-adjusting mechanism that mostly is screw thread transmission cutter piece adopting at present, or knife bar radial slippage threaded adjusting mechanism.When knife bar size just cannot realize compared with the micro-adjusting mechanism of hour screw thread transmission, knife bar radial slippage threaded adjusting mechanism has affected the stability of knife bar.
Summary of the invention
For after better realizing tool wear or processing dimension change aperture knife tool adjustment, the invention provide a kind of simple in structure, interchangeability good, precision keeps stable, wieldy centering type cutter fine adjustment mechanism, turned position by cutter spindle in tool rest eccentric orfice is realized point of a knife on knife bar and is regulated with respect to the size at tool rest center, completes the high accuracy processing in hole.
The technical scheme of the invention is: for the centering type cutter fine adjustment mechanism of hole in piece part processing, comprise knife bar, locking nut, elastic conical drogue, direction board, holding screw, Compress Spring, locking ball, tool rest.Described centering type cutter fine adjustment mechanism knife bar one end is provided with removable blade, the cylinder endoporus of the other end and tool rest closely cooperates, the endoporus of tool rest and benchmark cylindrical are designed with offset, and the cone of elastic conical drogue coordinates with the end taper hole of tool rest, and the interior cylindrical hole of elastic conical drogue coordinates with knife bar.Described locking nut by thread connection on tool rest, the large end face of the interior hole end surface pressing elastic conical drogue of locking nut.Described tool rest is provided with the radial location hole of locking ball, Compress Spring, holding screw effect.Axial location groove pressing on locking ball and knife bar, when knife bar rotates, locking ball can elastic yield.Described knife bar with locking ball contact-segment excircle on be also designed with axial location groove, knife bar rotate half cycle, point width tool rest reference center size generation respective change.When described locking nut pressing elastic conical drogue, knife bar is locked, and locking nut unclamps, and knife bar rotatably regulates.When described direction board mark knife bar rotates, point of a knife is adjusted variable quantity.
When application, unclamp locking nut, rotate knife bar according to locking ball effect be adjusted to need increment size, locking nut screws compression elastic conical drogue.Cutter completes centering type fine adjustment function.
