Embodiment
As shown in figure 1, the present invention Mechanical Driven making Nano surface device include tool heads 1, guide sleeve 2, drive plate 3,
Wear-resistant ball 4, ripple wear-resistant sleeve 5, air motor 6, shell 7.
In guide sleeve 2, tool heads 1 are closely assembled in the centre bore of drive plate 3, along the axis of guide sleeve 2 together with drive plate 3
Move reciprocatingly；
The circumference uniform distribution of wear-resistant ball 4 mounted in drive plate 3 radial hole in, and simultaneously with the corrugated surface of ripple wear-resistant sleeve 5
Concave surface or convex surface contact；Ripple wear-resistant sleeve 5 is on the output shaft of air motor 6；
Guide sleeve 2 is connected with air motor 6, and is arranged at intracavitary in shell 7, and can be moved back and forth along the inner chamber of shell 7
The contact surface of ripple wear-resistant sleeve 5 and drive plate 3 be corrugated surface, described corrugated surface for uniformly alternately convex surface with it is recessed
Face, as shown in Figure 2 and Figure 3, when tool heads 1 for workpieces processing with holding out against, with the convex surface and concave surface of wear-resistant ball 4 and corrugated surface
Constantly alternately contact, band nutating disk 3 moves reciprocatingly with tool heads 1 along axis.
Shell 7 can be constructed to the convenient clamping on the process equipments such as lathe, milling machine, planer, grinding machine and machining center
Form.
During work, tool heads 1 are withstood on workpiece to be processed.Compressed air is linked into the air inlet of air motor 6, from gas
The gas that dynamic motor 6 enters is partly into motor and drive motor revolution, another part enter the inner chamber of shell 7, and acts on
On air motor 6 and guide sleeve 2, under the transmission of ripple drive sleeve 5, wear-resistant ball 4 and drive plate 3, make tool heads 1 with certain
Pressure withstand on workpiece to be processed.
Under compressed gas effect, the rotation of the main shaft of air motor 6, ripple drive sleeve 5 is driven to rotate.Wear-resistant ball 4 is along ripple
The corrugated surface of line drive sleeve 5 rolls, and when concave surface of the wear-resistant ball 4 along ripple drive sleeve corrugated surface is moved to convex surface, wear-resistant ball 4 is logical
Crossing drive plate 3 promotes tool heads 1 to hit workpiece surface to be added, is plastically deformed finished surface；When wear-resistant ball 4 crosses ripple
During the convex surface in face, the reaction force in face to be processed promotes wear-resistant ball 4 along corrugated surface convex surface to concave surface by tool heads 1, drive plate 3
Roll.In this manner it is achieved that when the main shaft high-speed rotation of air motor 6, tool heads 1 are constantly reciprocating, and high frequency hits
Workpiece surface to be added, workpiece surface to be added is set constantly to be plastically deformed, crystal grain gradually refine to nanometer scale.
