A kind of numerical control minute surface lathe servo turret
[technical field]
The utility model relates to metal surface mirror finish apparatus field, especially relates to a kind of being arranged in numerically controlled lathe for workpiece being carried out to the servo turret device of mirror finish.
[background technology]
Known, numerical control micro-nano minute surface light lathe is to adopt diamond cutter to carry out the lathe of surface of the work pressure polishing processing, it utilizes metal in the feature of the cold plasticity of normal temperature state, by cutter, push surface of the work is applied to certain pressure, thereby make workpiece surface metal produce Plastic Flow, and be filled in original residual indentation trough, and then reach the roughness value that reduces surface of the work, surface of the work is presented have the object of the bright mirror surface of micro-nano precision, be that minute surface lathe is that the nao-and micro relief of surface of the work is planished, thereby by changing workpiece surface structure, mechanical property, shape and size, reach acquisition bright and clean as the object of the metal surface of mirror, yet, due to the servo turret using in existing numerical control minute surface lathe in process not only easily because the vibrations of lathe cause the minute surface processing to occur trueness error, but also likely cause the damage of cutter, and then cause the micro-nano mirror surface accuracy of the surface of the work processing more unstable, useless, defect rate is relatively high.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of numerical control minute surface lathe servo turret, described servo turret can effectively be avoided the lathe vibration influence being subject to, thereby reaches reduction mismachining tolerance, reduces object useless, substandard products amount.
For achieving the above object, the utility model adopts following technical scheme:
A numerical control minute surface lathe servo turret, described servo turret comprises planker, ball-screw, hydraulic pressure guide rail, hydraulic pressure slide block, knife rest and cutter; Described planker bottom is slidably connected with the lathe leading screw that is arranged on lathe upper side, and planker top is fixed with lathe leading screw and is cross-shaped ball-screw, and the both sides of corresponding ball-screw are fixed with respectively a hydraulic pressure guide rail; The two described hydraulic pressure guide rails clamping one hydraulic pressure slide block that jointly slides, middle part and the ball-screw of this hydraulic pressure slide block are slidably connected, and in the upper side of hydraulic pressure slide block, are fixed with the knife rest that cutter is installed.
Described numerical control minute surface lathe servo turret, described cutter is natural diamond.
Owing to adopting technical scheme as above, the utlity model has following beneficial effect:
Numerical control minute surface lathe described in the utility model can meet under the precondition of high-speed production with servo turret, effectively avoid the impact from lathe vibrations suffered in Tutrning Process, thereby the error of the workpiece mirror surface accuracy that processes is obviously reduced, and then effectively reduced the quantity of waster, accordingly for user has increased economic well-being of workers and staff.

[specific embodiment]
By the following examples, can explain in more detail the present invention, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Numerical control minute surface lathe servo turret described in 1~2 by reference to the accompanying drawings, described servo turret comprises planker 1, ball-screw 4, hydraulic pressure guide rail 5, hydraulic pressure slide block 6, knife rest 7 and cutter 8, described planker 1 bottom is slidably connected with the lathe leading screw 3 that is arranged on lathe 2 upper side, thereby is convenient to adding man-hour by lathe leading screw 3 drive servo turrets moving axially along workpiece, planker 1 top is fixed be cross-shaped ball-screw 4 corresponding to lathe leading screw 3, in the both sides of the corresponding ball-screw 4 of planker 1 upper side, be fixed with respectively a dynamic pressure hydraulic pressure guide rail 5 simultaneously, the common clamping one hydraulic pressure slide block 6 that slides of these two dynamic pressure hydraulic pressure guide rails 5, the middle part of this hydraulic pressure slide block 6 and ball-screw 4 are slidably connected, and the upper side at hydraulic pressure slide block 6 is fixed with the knife rest 7 that Natural Diamond Tools 8 is installed, described knife rest 7 can moving with cutter 8 moving radially along workpiece on dynamic pressure hydraulic pressure guide rail 5 by hydraulic pressure slide block 6, thereby reach the object that can make cutter 7 suitably contact with the outer surface of workpiece at any time in process, and then the error of the workpiece mirror surface accuracy that processes is obviously reduced.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
