Description
Technical field
The present invention relates to mechanical manufacturing field, relate in particular to a kind of turning attachment.
Background technology
Aborning, often can run into by Internal Spherical Surface, ball-and-socket or inner arc surface form workpiece, as shown in Figure 1, generally process the instrument of great circle cambered surface, adopt worm gear, worm mechanism to realize the gyration of cutter more.For the small quantities of part of the less single-piece of arc radius, commonly use form tool or catch up with the way of cutter to process by hand.But the cambered surface for arc radius between R35～R60mm, if adopt worm gear to be subject to the restriction of structure, with form tool with catch up with skill in using a kitchen knife in cookery processing also to have certain difficulty, and labour intensity is large, crudy is difficult for guarantee.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the turning attachment that has proposed a kind of simple in structure, easy for installation, simple to operate and satisfied certain required precision.
Technical solution of the present invention is achieved in that turning attachment, comprise body of tool, drive screw, rotating nut, rotation pin, benchmark pivot pin and revolution cutter holder, drive screw one end is mounted on rotating nut on body of tool, the other end is connected to revolution cutter holder one end by rotating pin, the other end of revolution cutter holder is installed lathe tool, revolution cutter holder middle part is arranged on body of tool by benchmark pivot pin again, and axle rotates centered by benchmark pivot pin; When work, rotate rotating nut, drive screw is under the effect of rotating nut, move along drive screw axis direction, and drive rotation pin to move, rotate pin and drive again revolution cutter holder to rotate as axle center taking the central axis of benchmark pivot pin, meanwhile, rotate pin and rotating nut rotation along with the variation of drive screw axis and body of tool axis angle.
Further, described rotating nut is connected on body of tool by nut bracket.
Further, described rotating nut is connected with handle.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Turning attachment of the present invention, simple in structure, the lathe tool radius of gyration has certain adjustment amount, can meet the processing of different radii inner arc surface workpiece in certain limit; Because the radius of gyration of Lathe tool tip can be controlled with measuring, and rotating screw bolt can reach even feeding, so just can meet certain required precision; And easy for installation, simple to operate, can meet the processing of different radii inner arc surface in certain limit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Shown in accompanying drawing 2,3,4, turning attachment of the present invention, comprises body of tool 3, drive screw 6, rotating nut 8, rotates pin 5, benchmark pivot pin 4 and turn round cutter holder 2.Drive screw 6 one end are mounted on rotating nut 8 on body of tool.The other end is connected to revolution cutter holder 2 one end by rotating pin 5.The other end of revolution cutter holder 2 is installed lathe tool 1.Revolution cutter holder 2 middle parts are arranged on body of tool 3 by benchmark pivot pin 4 again.And axle rotates centered by benchmark pivot pin 4.When work, rotate rotating nut 8.Drive screw 6, under the effect of rotating nut 8, moves along drive screw 6 axis directions.And drive rotation pin 5 to move.Rotating pin 5 drives again revolution cutter holder 2 to rotate as axle center taking the central axis of benchmark pivot pin 4.Meanwhile, rotate pin 5 and rotating nut 8 rotation along with the variation of drive screw 6 axis and body of tool 3 axis angles.
Rotating nut 8 of the present invention is connected on body of tool 3 by nut bracket 7.
As further improvement, described rotating nut 8 is connected with handle 9.
As shown in Figure 3, in the time of turning handle 9, drive screw 6, under the effect of rotating nut 8, produces along the movement of the screw axis direction of drive screw 6, and drives rotation pin 5 to move.Because rotate the center of pin 5 to the distance at benchmark pivot pin 4 centers, on revolution cutter holder 2, be a definite value, drive revolution cutter holder 2 to rotate as axle center taking the central axis of benchmark pivot pin 4 so rotate pin 5.Meanwhile, rotate pin 4 and rotating nut 8 rotation along with the variation of rotating screw bolt 6 axis and body of tool 3 axis angles, so just making to turn round cutter holder 2 can rotate continuously.The point of a knife that is contained in the lathe tool 1 on revolution cutter holder 2, with the rotation of revolution cutter holder 2, just the distance taking point of a knife to benchmark pivot pin 4 centers, as radius, is made the circular motion of cutting circle cambered surface.
On knife rest, install time of the present invention, first preset the distance of point of a knife to benchmark pivot pin 4 centers, make it equal the radius of processed inner arc surface.After the point of a knife radius of gyration is determined, according to the method for usual installation lathe tool, clamping of the present invention, on knife rest, is then adjusted in the horizontal plane that point of a knife height to the lathe spindle centre of gyration passes through.Again benchmark pivot pin 4 centers are adjusted to workpiece to be machined inner arc surface home position and are overlapped, then by longitudinal and transverse planker locking position, by handle 9 scales to zero-bit.
When turning, according to the number of allowance, lathe tool 1 is exited by zero-bit, position of tool tip is adjusted to and in the direction that can control cutting depth, is carried out tool setting, and remember scale value, again point of a knife is forwarded to the original position of workpiece cutting circle cambered surface, can carry out half finish turning and finish turning, until the scale of planker enters zero-bit.
For the more workpiece of allowance, to use before the present invention just employing to catch up with the skill in using a kitchen knife in cookery first workpiece inner arc surface to be carried out rough turn, and then half finish turning and finish turning as stated above.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
