Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and embodiments.
As shown in Figure 1:A kind of grinding and polishing executing agency for hyperbolic mirror machining tool, including be driven by motor and turn Dynamic main shaft 1, the top of main shaft 1 is equipped on excessive tieing 6 and excessively tieing 6 and is fixed with convex hyperboloid mold 7, in convex hyperboloid The bottom of lens gripper 8 right above mold 7 is equipped with eyeglass to be processed and the X-axis of eyeglass to be processed and convex hyperboloid mold 7 X-axis be arranged in parallel, the middle part of lens gripper 8 is equipped with balancing point slot 9, in the lower end insertion balancing point slot 9 of reciprocal balancing point 10 and eyeglass The contact of fixture 8 is connected;Make to rotate synchronously in the convex hyperboloid mold 7 of the drive of main shaft 1 and lens gripper 8 and lens gripper 8 is past Enable to the Y-axis of the relatively convex hyperboloid mold 7 of lens gripper 8 reciprocating under the action of physical pendulum needle 10.In above structure On the basis of, strut 11 is fixedly installed on lens gripper 8, the end of strut 11 is erected in the locating slot of swinging frame 5 and energy Enough relative positioning slots make stretching motion, and the bottom of two swinging frames 5 is separately fixed at the two sides of swinging disc 4, and the setting of swinging disc 4 exists Enable in support shaft 3 swinging disc 4 with respect to support shaft 3 swing, support shaft 3 be fixed in the support plate 2 being arranged on main shaft 1 and Support plate 2 is located at the lower section for the excessive tieing 6 being arranged at the top of main shaft 1.
Illustrate that the grinding and polishing provided by the present invention for hyperbolic mirror machining tool is held below by specific embodiment Row mechanism.
By taking the hyperboloid eyeglass of 60*60/RX300/RY200 as an example, will be needed on eyeglass to be processed first with X-axis on pencil drawing Relevant center line vertical to Y-axis is mounted on back lens surface to be processed on lens gripper 8 and lens gripper 8 with binder The axis of axis and eyeglass to be processed will be overlapped;Then eyeglass to be processed is placed closest to frosted in the convex mold of spherical surface R value, And obtain the concave spherical surface of a best-fit sphere;Finally eyeglass to be processed is placed on the convex hyperboloid mold 7 of RX300, RY200 And the corresponding coincidence of the X-axis line of lens gripper 8, the X-axis line of Y-axis line and convex hyperboloid mold 7, Y-axis line, work of the main shaft 1 in motor It is rotated counterclockwise under, then support plate 2, support shaft 3, swinging disc 4, swinging frame 5, excessive tieing 6, convex hyperboloid mold 7, eyeglass Fixture 8 and strut 11 follow main shaft 1 to rotate counterclockwise, and the X-axis of eyeglass and the X-axis of convex hyperboloid mold 7 are pressed from both sides in eyeglass at this time Parallel synchronous makees spinning motion, while the reciprocating motion driving eyeglass folder of reciprocal balancing point 10 in a counterclockwise direction under the action of tool 8 The Y-axis for having 8 relatively convex hyperboloid molds 7 is reciprocating, and strut 11 makees stretching motion with respect to the locating slot of swinging frame 5, i.e., Reciprocal curvilinear motion is done through 7 center of excess convexity hyperboloid mold in the Y-axis center of eyeglass to be processed, in machine run, mirror to be processed Between piece and convex hyperboloid mold 7 plus shot diamond dust, eyeglass to be processed and convex 7 phase of hyperboloid mold under certain pressure effect Recessed hyperboloid eyeglass is obtained after mutual friction, which can regard that a circular arc is rotated by axis of another circular arc as It forms, aspherical crosses to be formed for two.
In above process, by adjusting the amplitude of fluctuation of reciprocal balancing point 10, control R is worth change direction, by together One is obtained after the grinding of road diamond dust and meets the surface that rear road polishing requires, and polishing mold is using bigger than workpiece to be processed shape On 10% convex toric mold plus mixing polishing glue forms, and the convex double-curved surface face type of polished die is the heat by workpiece curved surface Replicate, in process by adjust amplitude of fluctuation, pressure, revolving speed and to the processing of polished die after, can be obtained One R positive and negative 0.5mm of value worst error, III grade of surface smoothness, surface precision error is less than the product of 0.005pm.It will swing The scale value of disk 4 becomes toward big direction, then R value becomes toward small direction;The scale value of swinging disc 4 is become toward small direction, then R value Become toward big direction;Then R value becomes toward small direction for pressure value increase;The more high then R value of the revolving speed of swinging disc 4 becomes toward big direction It is faster.The surface treatment of polished die refers to:Shallow among polished die groove depth when R value is bigger than normal, edge is deep, and R value polishes when less than normal Deep among mould groove depth, edge is shallow.
The present invention by the combination of rotation and reciprocally swinging so that eyeglass in fixture under certain pressure effect with mold Recessed hyperboloid eyeglass is obtained after phase mutual friction, which has the characteristics that structure is simple, performance is stable, is suitable for It promotes the use of.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention Within;The technology that the present invention is not directed to can be realized by the prior art.
