Description
Technical field
The utility model belongs to the technical field of engine lathe, and in particular to a kind of adjustable blade holders.
Background technology
Knife rest is the critical function part on lathe, is mainly used in installing all kinds of cutters of lathe and band cutter realizes two
The plane motion of dimension, so as to realize the turnery processing of slewing parts, traditional lathe saddle mainly includes knife rest matrix, adjusting pad
Piece, fishbolt, locking wrench and turning cutting tool.In turnery processing, point of a knife point and the rotary part axle center of turning cutting tool
Line needs to keep same level highly, so just can guarantee that being smoothed out for turnery processing.Traditional lathe saddle is generally used
Adjust tool nose point highly in the mode of the metallic gasket of tool base addition different-thickness so that tool nose point with return
Turn part axial line to be in same level.This regulative mode cannot exactly adjust tool nose point height and adjust
Come very cumbersome.In addition knife rest matrix, cutter and metallic gasket directly contact can make the overall system damping very little of knife rest, therefore
In turning process, easily there is the phenomenon of vibration cutting, not only have impact on turnery processing quality but also exacerbated the damage of cutter.In
(December 13 2011 applying date, authorized announcement date 2012 year 08 month 22 days are authorized state's utility model patent " adjustable blade holders "
The U of notification number CN 202387966) a kind of adjustable lathe saddle is disclosed, it uses regulating bolt to promote adjustment sliding block oblique
Moved on face, the horizontal movement for adjusting sliding block is converted into vertical movement, and promote cutter in the vertical direction to move, so that real
The adjustment of existing tool nose point height, this mode is easy to adjust.But, this adjustable blade holders be still present it is following some not
Foot：One, the relative motion of in the vertical direction is deposited between adjustment sliding block and regulating bolt, therefore in adjustment sliding block and regulating bolt
Contact surface on there is larger frictional resistance, can make regulating bolt be in course of adjustment tighten it is relatively elaborate or even stuck；Two,
There is no any anti-skid structure on adjustment sliding block, adjustment sliding block easily slides in the presence of cutter extruding force, so as to cause cutter
Clamping even causes the accident built on the sand；Three, this kind of adjustable blade holders do not account for knife rest vibration damping problem, are not provided with any vibration damping
Device, equally easily causes the vibration of cutter, so as to influence turnery processing quality.
Above-mentioned discussion content purpose is may be with the utility model being described below and/or advocate to reader's introduction
The related technology of various aspects various aspects, it is believed that the discussion content helps to be reader with background's information, with favourable
