Description
Technical field
The present invention relates to a kind of knife rest, especially process the knife rest of slender axles external diameter.
Background technology
In machining, the external diameter of axial workpiece is arranged on the chuck of lathe typically by lathe process, workpiece one end
On, the other end withstands on top by centre bore, and workpiece is rotated by chuck, and lathe tool is arranged on knife rest, leads along lathe
Rail has moved along a straight line the processing of external diameter of axial workpiece.But in actual applications, need that slender axles are carried out external diameter and add
Work, such as the power transmission shaft of helicopter, its draw ratio L/D is more than 20, even up to 40.This kind of part is adding man-hour, due to carefully
The weight of major axis self, after mounting, slender axles can produce certain flexural deformation, and the position of processing is not the mother along slender axles
Line, but form a curve, after causing slender shaft turning, the middle surplus removed is few compared with two ends, in shuttle after the processing of line length axle
Shape, linearity index can not meet requirement.The method solved at present is to increase supporting construction at the middle part of slender axles, but this
Mode also can produce certain bending between the strong point and installation site, it is impossible to is fully solved diastrophic problem, meanwhile,
The supporting construction of this increase tends to foul with the processing of part, needs to adjust at any time, and to ensure the axle of line length axle before and after adjusting
Line position is constant, complex operation, and efficiency is low.
Summary of the invention
It is an object of the invention to provide a kind of knife rest, by this knife rest, it is ensured that the external diameter of thin and long shafts part adds working medium
Amount, and have simple to operate, the feature that working (machining) efficiency is high.
The concrete technical scheme of the present invention is, described knife rest include tool shank cartridges, support arm, adjustment stud, adjust nut,
Compression spring, fastening bolt, described tool shank cartridges is provided with lathe tool, and support arm is fixed under tool shank cartridges by fastening bolt
Portion, the front end of support arm extends to the bottom of slender axles to be processed, and is provided with through hole below the axis of slender axles, adjusts spiral shell
Stake passes on the through hole of support arm and is provided with in support arm bottom and adjusts the adjustment nut that stud matches, and top is provided with compression bullet
Spring, described compression spring one end is pressed in the upper surface of support arm, and the other end is pressed in and adjusts on the step arranged on stud, described
Adjustment stud, under the effect of compression spring, adjusts nut by rotating, can contact with the bottom of slender axles to be processed, adjusts
The top of whole stud is provided with ball free to rotate.Being provided with kidney slot on support arm, fastening bolt passes kidney slot by support arm
It is fixed in tool shank cartridges.
As the another kind of technical scheme of the present invention, support arm is fixed on the top of tool shank cartridges by fastening bolt, before support arm
End extends to the top of slender axles to be processed, and is provided above through hole at the axis of slender axles, adjusts stud through support arm
Being provided with on through hole and on support arm top and adjust the adjustment nut that stud matches, bottom is provided with compression spring, described pressure
Contracting spring one end is pressed in the lower surface of support arm, and the other end is pressed in and adjusts on the step arranged on stud, on described adjustment stud also
Being fixed with curved wall, the other end of described curved wall is walked around slender axles to be processed and extends to the bottom of slender axles, described curved wall
Under the effect of compression spring and adjustment stud, adjust nut by rotating, can contact with the bottom of slender axles to be processed,
The position contacted with the bottom of slender axles to be processed on curved wall is provided with ball free to rotate.Kidney-shaped it is provided with on support arm
Groove, support arm is fixed in tool shank cartridges by fastening bolt through kidney slot.
The present invention, by installing support arm in tool shank cartridges, by regulating the position of support arm, makes ball on adjustment stud and treats
Contacting bottom processing slender axles, in the course of processing, ball is connected firmly by support arm, tool shank cartridges etc., and then its direction of motion and car
Bed guide rail parallel, thus the flexural deformation that slender axles to be processed produce can be eliminated because of action of gravity, it is ensured that lathe tool is along slender axles
Bus motion, thus ensure that the crudy of slender axles outer surface.Meanwhile, as the another kind of technical scheme of the present invention,
Adjust nut and be arranged on top, adjust convenient, may also adapt to different operating environments simultaneously.The present invention before processing will
After the regulation of each parts, just can be processed operation, midway need not carry out any adjustment again, easy to use, efficiency
Height, processing effect is good.
