Specific embodiment
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1：A kind of grinding and polishing actuator for hyperbolic mirror machining tool, including being turned by Motor drive
Dynamic main shaft 1, the top of main shaft 1 is provided with excessive tieing 6 and excessive tieing 6 and is fixed with convex hyperboloid mould 7, in convex hyperboloid
The bottom of the lens gripper 8 directly over mould 7 is provided with eyeglass to be processed and the X-axis of eyeglass to be processed and convex hyperboloid mould 7
X-axis be arranged in parallel, the middle part of lens gripper 8 is provided with balancing point groove 9, with eyeglass in the lower end insertion balancing point groove 9 of reciprocal balancing point 10
The contact of fixture 8 is connected；The convex hyperboloid mould 7 of drive in main shaft 1 and lens gripper 8 makees synchronous axial system and lens gripper 8 is past
The Y-axis for enabling to the convex hyperboloid mould 7 relatively of lens gripper 8 in the presence of physical pendulum pin 10 is reciprocating.In said structure
On the basis of, it is fixedly installed pole 11 on lens gripper 8, the end of pole 11 is erected in the locating slot of swing span 5 and energy
Enough relative localization grooves make stretching motion, and the bottom of two swing spans 5 is separately fixed at the both sides of wobble-plate 4, and wobble-plate 4 is arranged on
So that 4 relative support axle 3 of wobble-plate is swung in support shaft 3, support shaft 3 be fixed on main shaft 1 arrange support plate 2 on and
Support plate 2 is located at the lower section of the excessive tieing 6 of 1 top of main shaft setting.
Illustrate to hold provided by the present invention for the grinding and polishing of hyperbolic mirror machining tool below by specific embodiment
Row mechanism.
By taking the hyperboloid eyeglass of 60*60/RX300/RY200 as an example, will be needed with X-axis on pencil drawing on eyeglass to be processed first
Related centrage vertical to Y-axis, with binding agent back lens surface to be processed on the lens gripper 8 and lens gripper 8
The axis of axis and eyeglass to be processed will overlap；Then eyeglass to be processed is placed closest to frosted in the convex mold of sphere R value,
And draw the concave spherical surface of a best-fit sphere；Finally eyeglass to be processed is placed on the convex hyperboloid mould 7 of RX300, RY200
And the X-axis line of lens gripper 8, Y-axis line and the X-axis line of convex hyperboloid mould 7, Y-axis line is corresponding overlaps, main shaft 1 is in the work of motor
With under rotate counterclockwise, then support plate 2, support shaft 3, wobble-plate 4, swing span 5, excessive tieing 6, convex hyperboloid mould 7, eyeglass
Fixture 8 and pole 11 follow main shaft 1 to rotate counterclockwise, and now the X-axis of eyeglass is pressed from both sides in eyeglass with the X-axis of convex hyperboloid mould 7
In the presence of tool 8, parallel synchronous make spinning motion in a counterclockwise direction, while the reciprocating motion of reciprocal balancing point 10 drives eyeglass folder
The Y-axis of 8 convex hyperboloid moulds 7 relatively of tool is reciprocating, and stretching motion made by the locating slot of 11 opposing oscillatory frame 5 of pole, i.e.,
Reciprocal curvilinear motion is done through 7 center of excess convexity hyperboloid mould in the Y-axis center of eyeglass to be processed, in machine run, mirror to be processed
Add shot corundum between piece and convex hyperboloid mould 7, eyeglass to be processed and convex 7 phase of hyperboloid mould under certain pressure effect
Recessed hyperboloid eyeglass is obtained after mutual friction, and the hyperboloid eyeglass can regard that a circular arc is rotated with another circular arc as axis as
Form, be that two aspheric surfaces cross to be formed.
In above process, by the amplitude of fluctuation of the reciprocal balancing point 10 of regulation, control R is worth change direction, through together
One being obtained after the grinding of road corundum and meeting the surface that the polishing of rear road is required, polishing mould is using bigger than workpiece to be processed profile
Mixing polishing glue is added to form on 10% convex toric mold, the convex toroid face type of polished die is the heat by workpiece curved surface
Duplication is formed, in process by adjust amplitude of fluctuation, pressure, rotating speed and to the process of polished die after, you can obtain
The positive and negative 0.5mm of one R value maximum error, III grade of surface smoothness, product of the surface precision error less than 0.005pm.To swing
The scale value of disk 4 becomes toward big direction, then R value becomes toward little direction；The scale value of wobble-plate 4 is become toward little direction, then R value
Become toward big direction；Then R value becomes toward little direction for pressure value increase；The rotating speed of wobble-plate 4 is more high, and R value becomes toward big direction
Faster.The surface treatment of polished die is referred to：When R value is bigger than normal, shallow, edge depth in the middle of polished die groove depth, polishes when R value is less than normal
Deep in the middle of mould groove depth, edge is shallow.
The present invention by rotate and reciprocally swinging combination so that the eyeglass in fixture certain pressure effect under with mould
Recessed hyperboloid eyeglass is obtained after phase mutual friction, and the grinding and polishing actuator has the characteristics that simple structure, stable performance, suitably
Promote the use of.
Above example technological thought only to illustrate the invention, it is impossible to which protection scope of the present invention is limited with this, every
According to technological thought proposed by the present invention, any change that is done on the basis of technical scheme, the scope of the present invention is each fallen within
Within；The technology that the present invention is not directed to all can be realized by prior art.
