Description
Technical field
This utility model relates to the horizontal tool head mechanism technology field being applied on numerically controlled lathe, especially
Relate to a kind of knife rest using built-in Rhizoma Sparganii tapered sleeve.
Background technology
At present, existing numerical control horizontal knife rest, such as machining crankshafts on rack of digital controlled crankshaft lathe, due to
When the particularity of crankshaft type part, turning crankshaft main-shaft diameters and connecting rod neck, it is necessary to make knife bar extension elongation
More than turning the footpath degree of depth, typically can lengthened tool arbor cantilevered length.Otherwise, footpath can be turned by bent axle to be limited
And interference.Prior art generally uses cutter, knife bar, receiving device, cutterhead, cutter tower and screw etc.
Assembly.Each side being i.e. provided with cutter limit shape cylinder on the most bars of cutterhead is fitted with one
Receive device, receive, on device, knife bar is installed.Through needing eight knife combinations, complete whole bent axle
The course of processing of the Roughing and fine machinings such as the surfaces externally and internally of rod journal cylindrical, circle root and revolving body.Or
Normal conventional digital control vertical knife rest is installed lengthened tool arbor and carries out turning.Said structure mode is the most often
It is that the rigidity of the cutter caused is not enough, when machining crankshafts owing to knife bar overhangs long, it is easy to send out
Raw knife bar vibration, directly affects the machining accuracy of the lathe adding man-hour, even cannot process Large Crankshaft.
Causing workpiece not reach technology requirement, qualification rate reduces, cutter changing rapid, adds and adds
Work cost, reduces productivity ratio.
Summary of the invention
The purpose of this utility model is to avoid the defect of prior art to provide a kind of and use built-in three
The knife rest of pyramid sleeve, efficiently solves the problem that prior art exists.
For achieving the above object, the technical scheme that this utility model is taked is: described one uses built-in
The knife rest of formula Rhizoma Sparganii tapered sleeve, is characterized in including cutter tower, cutterhead is fixedly mounted on cutter tower by the second screw
On, cutterhead embedding and is provided with built-in Rhizoma Sparganii tapered sleeve, knife bar is arranged in built-in Rhizoma Sparganii tapered sleeve, cutter
Cutter it is provided with on bar.
Described built-in Rhizoma Sparganii tapered sleeve is fixedly linked with cutterhead by the first screw.
Described built-in Rhizoma Sparganii tapered sleeve is the hollow tapered sleeve of triangular pyramid with end surface supporting, and hole taper is
1:20。
The beneficial effects of the utility model are: described a kind of knife rest using built-in Rhizoma Sparganii tapered sleeve, its
It is provided with built-in Rhizoma Sparganii tapered sleeve in cutterhead and knife bar junction and increases cutter diameter, decrease receiving device ring
Joint, can be directly inserted into knife bar in dish, substantially increase the rigidity of cutter, reduce lathe cost,
Improve work efficiency.In turning process, it is not necessary to change cutter, it is possible to ensure the seriality of turning,
Improve crudy；Bearing capacity is big, and rigidity is high, and absorbing is good；By interior circulating cooling passage, energy
Enough cutting fluid is transported to cutting zone, in use plays lubrication effect, greatly reduce
The thermal deformation of workpiece, thus ensure precision and the surface roughness of workpiece.Improve the quality of workpiece, subtract
Light labor strength, improves production efficiency.

Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for solving
Release this utility model, be not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, described a kind of knife rest using built-in Rhizoma Sparganii tapered sleeve, it is characterized in bag
Including cutter tower 3, cutterhead 4 is fixedly mounted on cutter tower 3 by the second screw 7, embeds and arrange in cutterhead 4
Having built-in Rhizoma Sparganii tapered sleeve 5, knife bar 2 is arranged in built-in Rhizoma Sparganii tapered sleeve 5, and knife bar 2 is provided with
Cutter 1.
Further, described built-in Rhizoma Sparganii tapered sleeve 5 is fixedly linked with cutterhead 4 by the first screw 6.
Further, as shown in Figures 3 and 4, described built-in Rhizoma Sparganii tapered sleeve 5 is for have end surface supporting
The hollow tapered sleeve of triangular pyramid, hole taper is 1:20.As HSK pad, can implementation tool handle cone
Face is with only by the contact location of end face, and polygon taper shank may insure that automatic radial centering, is characterized in logical
Cross the gapless location shaping locking implementation tool handle between the hollow taper shank of triangular pyramid and triangular pyramid taper hole, from
And without using such as keyway and the driving such element of key just can transmit bigger torque.This instrument makes
Handle of a knife handle has that size is little, lightweight, rigidity is high, tool-changing speed is fast and tool changing precision is high, and has one
