Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described with embodiment.
As shown in Figure 1：A kind of grinding and polishing actuator for hyperbolic mirror machining tool, including by Motor drive turn
Dynamic main shaft 1, the top of main shaft 1 is provided with excessive tieing 6 and excessively 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；Make synchronous axial system in the convex hyperboloid mould 7 of the drive of main shaft 1 and lens gripper 8 and lens gripper 8 is past
The Y-axis that the relatively convex hyperboloid mould 7 of lens gripper 8 is enabled in the presence of physical pendulum pin 10 is reciprocating.In said structure
On the basis of, pole 11 is fixedly installed 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
The relative support axle 3 of wobble-plate 4 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 that the top of main shaft 1 is arranged.
Illustrate that the grinding for hyperbolic mirror machining tool that this utility model is provided is thrown below by specific embodiment
Light actuator.
By taking the hyperboloid eyeglass of 60*60/RX300/RY200 as an example, will need first on eyeglass to be processed with X-axis on pencil drawing
Vertical to Y-axis related centrage, is arranged on back lens surface to be processed on lens gripper 8 and lens gripper 8 with binding agent
The axis of axis and eyeglass to be processed will overlap；Then eyeglass to be processed is placed closest to into frosted in the convex mold of sphere R values,
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, work of the main shaft 1 in motor
Rotate counterclockwise with, 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 with the X-axis of convex hyperboloid mould 7 in eyeglass
Parallel synchronous make in a counterclockwise direction spinning motion in the presence of tool 8, while the reciprocating motion of reciprocal balancing point 10 drives eyeglass folder
The Y-axis of 8 relatively convex hyperboloid moulds 7 of tool is reciprocating, and the locating slot of the opposing oscillatory frame 5 of pole 11 makees stretching motion, i.e.,
Reciprocal curvilinear motion is done in the Y-axis center of eyeglass to be processed through the convex center of hyperboloid mould 7, in machine run, mirror to be processed
Add shot corundum between piece and convex hyperboloid mould 7, eyeglass to be processed and the convex phase of hyperboloid mould 7 under certain pressure effect
Recessed hyperboloid eyeglass is obtained after mutual friction, the hyperboloid eyeglass can regard that a circular arc rotates by axis of another circular arc 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 is obtained after the grinding of road corundum and meets the surface that rear road polishing 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 adjusting amplitude of fluctuation, pressure, rotating speed and process to 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 values become toward little direction；The scale value of wobble-plate 4 is become toward little direction, then R values
Become toward big direction；Then R values become toward little direction for pressure value increase；The rotating speed of wobble-plate 4 is more high, and R values become toward big direction
It is faster.The surface treatment of polished die is referred to：Shallow, edge depth in the middle of polished die groove depth, polishes when R values are less than normal when R values are bigger than normal
Deep in the middle of mould groove depth, edge is shallow.
This utility model by rotate and reciprocally swinging combination so that the eyeglass in fixture certain pressure effect under with
Recessed hyperboloid eyeglass is obtained after mould phase mutual friction, the grinding and polishing actuator has the characteristics of simple structure, stable performance,
Suitably promote the use of.
Above example is only to illustrate technological thought of the present utility model, it is impossible to limit protection model of the present utility model with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical scheme each falls within this reality
Within the scope of novel protected；The technology that this utility model is not directed to can be realized by prior art.
