Description
Technical field
The present invention relates to a kind of knife rest, especially the knife rest of processing slim axle external diameter.
Background technology
In machining, the external diameter of axial workpiece is normally processed by lathe, workpiece one end is arranged on the chuck of lathe, the other end by centre bore withstand on top on, workpiece is by chuck driven rotary, lathe tool is arranged on knife rest, completes the processing of the external diameter of axial workpiece along lathe guide rail rectilinear motion.But in actual applications, need to carry out to slender axles the processing of external diameter, as the power transmission shaft of helicopter, its draw ratio L/D is greater than 20, even reaches 40.This class part is adding man-hour, due to the weight of slender axles self, after installation, slender axles can produce certain flexural deformation, and the position of processing is not the bus along slender axles, but form a curve, cause after slender axles processing, the middle surplus of removing is few compared with two ends, after the processing of line length axle, is fusiformis, and linearity index can not meet the demands.The method solving is at present 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, can not solve diastrophic problem completely, simultaneously, the supporting construction of this increase tends to hinder the processing of part, need to adjust at any time, and will ensure that the axial location of the line length axle of adjusting front and back is constant, complex operation, efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of knife rest, by this knife rest, can ensure the external diameter crudy of thin and long shafts part, and have simple to operate, the feature that working (machining) efficiency is high.
Concrete technical scheme of the present invention is, described knife rest comprises tool shank cartridges, support arm, adjust stud, adjust nut, Compress Spring, fastening bolt, in described tool shank cartridges, lathe tool is installed, support arm is fixed on the bottom of tool shank cartridges by fastening bolt, the front end of support arm extends to the bottom of slender axles to be processed, and be provided with through hole below the axis of slender axles, adjust stud through on the through hole of support arm and be provided with in support arm bottom and the adjustment nut of adjusting stud and matching, top is provided with Compress Spring, described Compress Spring one end is pressed in the upper surface of support arm, the other end is pressed in to be adjusted on the step arranging on stud, described adjustment stud is under the effect of Compress Spring, adjust nut by rotation, can contact with the bottom of slender axles to be processed, the top of adjusting stud is provided with ball free to rotate.On support arm, be provided with kidney slot, fastening bolt is fixed on support arm in tool shank cartridges through kidney slot.
As another kind of technical scheme of the present invention, support arm is fixed on the top of tool shank cartridges by fastening bolt, the front end of support arm extends to the top of slender axles to be processed, and be provided with through hole above the axis of slender axles, adjust stud through on the through hole of support arm and be provided with on support arm top and the adjustment nut of adjusting stud and matching, bottom is provided with Compress Spring, described Compress Spring one end is pressed in the lower surface of support arm, the other end is pressed in to be adjusted on the step arranging on stud, on described adjustment stud, be also fixed with curved wall, the other end of described curved wall is walked around slender axles to be processed and is extended to the bottom of slender axles, described curved wall is under the effect of Compress Spring and adjustment stud, adjust nut by rotation, can contact with the bottom of slender axles to be processed, the position contacting with the bottom of slender axles to be processed on curved wall is provided with ball free to rotate.On support arm, be provided with kidney slot, fastening bolt is fixed on support arm in tool shank cartridges through kidney slot.
The present invention by installing support arm in tool shank cartridges, by regulating the position of support arm, the ball that makes to adjust on stud contacts with slender axles to be processed bottom, in process, ball connects firmly by support arm, tool shank cartridges etc., and then its direction of motion is parallel with lathe guide rail, thereby can eliminate the flexural deformation that slender axles to be processed produce because of Action of Gravity Field, ensure that lathe tool moves along the bus of slender axles, thereby ensured the crudy of slender axles outer surfaces.Meanwhile, as another kind of technical scheme of the present invention, adjust nut and be arranged on top, adjust conveniently, simultaneously can also adapt to different operating environments.The present invention just can carry out process operation after each parts being regulated before processing, does not need to carry out any adjustment midway again, and easy to use, efficiency is high, and processing effect is good.
