Description
Technical field
The present invention relates to big stroke high sensitivity Lathe tool tip high-precision adjusting apparatus lathes.
Background technology
The adjustment of Lathe tool tip high-precision can make the surface precision of processing reach nanoscale.The adjustment of turning tool height is part ratio
Cumbersome thing, the adjustment of traditional Lathe tool tip height can be divided into:The iron sheet of cushioning different-thickness, utilizes wedge below lathe tool handle of a knife
The adjustment of shape slope sawtooth, increases spring adjustment set below lathe tool handle of a knife.However, the excessively thin influence lathe tool rigidity of thickness of scale,
The adjustment dismounting of wedge slope sawtooth expends working hour, increases spring adjustment set and is unable to adjust to micron accuracies.Therefore, how to simplify
The height adjustment device of lathe tool improves machining accuracy, reduces and adjusts working hour, reduces production cost, is the skill that actual needs solves
Art problem.
Invention content
Present invention aims at provide a kind of big stroke high sensitivity Lathe tool tip high-precision adjusting apparatus, adjustment letter
It is single, grade may be implemented and adjusted to the nose height of micron order stroke resolution ratio.
Technical solution provided by the invention is：
1. including pedestal, the band being fixed thereon is locked into the straight-line guidance mobile mechanism (dovetail guide) of mechanism, installs
Movable tool-holder on linear moving mechanism sliding block, fixed tool apron, lock-screw, coarse adjustment screw, micrometer adjusting screw, pre-loading screw
And trimming handle.Further, square box shape lathe bed is by upper cover plate, left cover, right cover plate, five blocks of plates of back shroud and lower cover
Composition, constitutes a heat-staple rectangular five face structure, open one side is as sliding door installation space.
Further, it is characterised in that lathe tool is fixed on by its knife bar with the compact heap with guide-localization function removable
On moving knife seat, rotation coarse adjustment screw can be such that movable tool-holder is moved up and down in grade stroke after unclamping lock-screw, when
When position error arrival ± 0.05mm, can tighten lock-screw makes movable tool-holder be combined as a whole with fixed tool apron.Gu
There are one heavy caliber hole, the horizontal directions in hole to prolong open notch there are one center lines, the bottom of micrometer adjusting screw for the front end of stationary knife seat
Portion's nail passes through the upside of notch to be connect with downside, downside and upside is tensed, notch is made in the downside of notch, two pre-loading screws
Realize mechanical closure.Pre-loading screw top is installed below disk spring, when rotary fine adjustment screw can make disk spring compress or
Elongation, since using left side heavy caliber hole as fulcrum, leverage is according to point of a knife to the distance and micrometer adjusting screw of fixed tool apron front end
To the ratio of the distance of fixed tool apron front end, the micron order that point of a knife may be implemented moves up and down.So as to realize grade row
The micrometer resolution nose height of journey adjusts；
Further, the left side of fixed tool apron in the center of vertical direction there are one heavy caliber hole, the left side in hole in
The distance of fixed tool apron front end depends on material physical property and desired rigidity, the right side in hole there are one open notch,
The width of notch is more than the stroke that point of a knife is finely tuned up and down；
Further, there are at least two or more than two holes on the rear end top surface of fixed tool apron, one of them is used for pacifying
Micrometer adjusting screw is filled, remaining is used for installing pre-loading screw, and disk spring is housed below pre-loading screw ailhead.Micrometer adjusting screw is tightened,
Gap width can be made to increase, point of a knife is made to move down；Micrometer adjusting screw is unclamped, gap width is reduced, and point of a knife moves up.With pre-
The decrement of tight screw adjustment disk spring, can adjust the rigidity that can reach in vertical direction；
Further, the front end of fixed tool apron be equipped with band guiding can upper and lower linear moving mechanism, sliding block unclamping
It can be moved up and down by rotating coarse adjustment screw when lock-screw.Slot hole is provided on sliding block, width and the lock-screw in hole coordinate,
