Description
Technical field
This utility model relates to machining fixture, and the Fine Slender Shaft of a kind of band V-type annular groove is processed with auxiliary
Help device.
Background technology
The axle being more than 25 with diameter ratio generally for length is referred to as slender axles, due to slender axles poor rigidity (L/d value own
Bigger, rigidity is the poorest), occur the problem that in turning process workpiece by cutting force, conduct oneself with dignity and rotate time centrifugal force made
With, bending, vibration can be produced, have a strong impact on its cylindricity and surface roughness；Workpiece is in working angles, and workpiece is by thermal stretching
Produce flexural deformation.
Tradition processing slender axles, whether depend on follow-rest to complete turning at engine lathe or numerically controlled lathe, use
The follow-rest of three-jaw supporting, because lathe tool is to the resistance to cutting of workpiece, makes workpiece touch on three bearing claws of follow-rest, then adds
Upper lathe tool is formed for four surface pressures to slender axles, prevents axially deviation, stable during turning, is not likely to produce vibration, reduces
Deformation, thus improve the form accuracy of slender axles and reduce surface roughness；Follow-rest and turning cutting tool are arranged symmetrically with to turning
Cutter produce one counteracting force of cutting force, improve process system rigidity, thus eliminate or reduce processing in vibration and
Deformation.But the elongated optical axis that whether radial dimension is consistent, or long lead screw, work in-process is by the most added for tool dimension regulation
After work excircle dimension, axial feed motion only made by cutter, does not has radial motion, therefore can use follow-rest secondary process.
For the Fine Slender Shaft of band V-type annular groove, in the course of processing, do not only exist axial feed motion, and there is footpath
To motion, use follow-rest to cannot be carried out radially and process, in the course of processing, there is vibration, deform, and cannot ensure size and
The accuracy of form and position.
Summary of the invention
This utility model uses follow-rest processing to there is vibration, become for the Fine Slender Shaft solving existing band V-type annular groove
Shape and the problem that dimensional accuracy cannot be ensured, it is provided that the Fine Slender Shaft auxiliary device for processing of a kind of band V-type annular groove.
This utility model adopts the following technical scheme that realization: the Fine Slender Shaft of a kind of band V-type annular groove is processed with auxiliary
Helping device, including slender axles body, slender axles body is provided with centre frame, the left and right sides of centre frame is provided with damping
Frame, the front side of slender axles body is provided with hollow hand operated chuck, and hollow hand operated chuck front end is provided with and is connected with machine tool chief axis end
And the main shaft cylinder of inwall right boring, it being provided with the retainer with its interference fit in main shaft cylinder, main shaft cylinder front end is provided with main shaft and protects
Holding sleeve pipe, the sidewall of main shaft retaining sleeve is uniform has some regulation bolts being radially arranged；Retainer includes being enclosed within slender axles
Tensioner collet chuck on body, tensioner collet chuck overcoat has tensioner tapered sleeve, is cased with the cone with its cone match, tensioner outside tensioner tapered sleeve
The tensioner nut be close to its front surface and threaded with cone front side wall it is provided with on front side of tapered sleeve；Dynamic mount includes support body, frame
Body upper end is provided with support ring, uniform in support ring is provided with radially-arranged sleeve, is provided with bakelite fore-set in sleeve.
The setting of hollow hand operated chuck, solve numerically controlled lathe stroke ratio part length size little, and lathe cannot clamping
Technical problem；Processing must improve rotating speed to improve the roughness of product, thus the bending vibration of workpiece be relatively big, in order to subtract
Lacking VIBRATION DESIGN dynamic mount, dynamic mount supports Fine Slender Shaft, and the rigidity that improve process system decreases vibration；In order to carry
High-axiality and the deformation of minimizing workpiece, devise retainer and be supported Fine Slender Shaft, by tightening in retainer
Tensioner nut promotes tensioner tapered sleeve and cone to interact and makes tensioner collet chuck clamp workpiece, main shaft cylinder has been carried out right boring simultaneously,
Install retainer during clamping workpiece at right boring position, main shaft cylinder and retainer cylindrical ensure interference fits with addition of work, it is ensured that workpiece
Axiality；Design main shaft retaining sleeve is connected to machine tool chief axis end, and workpiece is filled in main shaft, shortens two ends three-jaw clamping workpiece
Length, be effectively increased the rigidity of process system, overcome existing band V-type annular groove Fine Slender Shaft use follow-rest processing
There is vibration, deformation and the problem that dimensional accuracy cannot be ensured.
This utility model reasonable in design is reliable, not only solves numerically controlled lathe stroke ratio part length size little, machine
Bed cannot the primary technical problem of clamping, and improve the rigidity of Fine Slender Shaft manufacturing process system, efficiently solve and add
Vibration in work, deformation and accurate to dimension problem cannot be ensured, have simple in construction, easy to process and low cost excellent
Point.
