Description
Technical field
The utility model relates to the cold worked equipment in optical glass elements face, specifically refers to a kind of to the cold worked large-scale polishing machine in optical glass elements face.
Background technology
To the plane machining of large-scale optical glass device, general employing large glass glass polishing machine at present.Existing large-scale glass polishing machine generally has a very large polishing disk, during processing operation, polishing disk constantly rotates around its central shaft, workpiece is placed in the workpiece plate on described polishing disk, and drive described workpiece to move according to certain rules on the polishing disk rotated by workpiece plate, to reach, the Even Grinding of surface of the work is processed.Due in the process of grinding, the flatness of the polished film on polishing disk can be damaged, and affects the machining accuracy of workpiece, therefore, in the process of processing or will carry out the correction of flatness after process finishing to polishing disk.Flatness timing is pressed on the polishing disk of rotation by the larger planar disk of a deadweight, drives calibration disc to move according to certain rules simultaneously and do radial motion relative to polishing disk, to reach the even finishing of the flatness to polishing disk.
The diameter of the polishing disk that current large-scale glass polishing machine rotates around its central shaft can reach 3-4m, axle is set up a newel wherein, simultaneously in the outside of polishing disk, even Boulez 3 heel posts, there is crossbeam each heel post is added, and form 3 portal structures that has central supported.The crossbeam of crane span structure sets up the driving mechanism of workpiece plate and the driving mechanism of calibration disc.
3 portal structures of central supported have shortcomings: 1. the restriction being subject to the centre bearing of polishing disk, and the diameter of newel can not do too large, therefore makes with newel the structural strength that support can affect crane span structure; 2. the vibration of polishing disk is delivered on crane span structure by newel, affects the stability of complete machine, also impacts the crudy of the high optical glass device of precision requirement; 3. the existence of newel, reduces the range of movement of workpiece plate and calibration disc; 4. the impurity of central supported can produce polishing disk card and pollute.
Summary of the invention
The purpose of this utility model is independent 3 portal structures providing a kind of large-scale glass polishing machine, by getting rid of original newel, thus simplifying structure, reducing costs, and improves stability and the machining accuracy of equipment.
The technical solution of the utility model is: a kind of independent three portal structures of large-scale glass polishing machine, three heel posts comprising polishing disk, be located at workpiece plate on polishing disk and calibration disc and be located at outside polishing disk, every root heel post sets up a crossbeam, described three crossbeams interconnect in polishing disk overcentre, form an independence three portal structures.
Further, described three crossbeams adopt rectangular steel tube to make, and are connected by one pair of upper and lower connecting plate.
The workpiece plate plate moving mechanism of described workpiece plate is driven to be located at respectively on described each crossbeam with driving the calibration disc plate moving mechanism of described calibration disc.
Feature of the present utility model is:
(1) after three portal structures of former newel and heel post common support being improved to independent three portal structures, simplifying the structure, assemble more convenient, reduce cost, overcome simultaneously and support with newel the shortcoming making to affect structural strength and stability.
(2) isolated the vibration of polishing disk to the impact of described three portal structures.
(3) when avoiding central shaft lubrication, maintenance, impurity is scattered or being scattered to the pollution of polishing disk card of the residual grain of abrasion of newel.

Detailed description of the invention
Now in conjunction with an embodiment and accompanying drawing thereof, the utility model is described in further detail.
By the schematic diagram that Fig. 1 is embodiment of the present utility model.Independent 3 portal structures of large-scale glass polishing machine, comprise polishing disk 4, be located at 3 heel posts 2 outside polishing disk 4, every root heel post 2 sets up a crossbeam 1, and described 3 crossbeams interconnect in polishing disk 4 overcentre, form an independence 3 portal structures.
Polishing disk 4 is located on a support, and can around its central rotation.Workpiece plate a 9 and workpiece plate b 6 and calibration disc 3 that polishing disk 4 is provided with.
3 crossbeams 1 adopt rectangular steel tube to make, and are connected with bolt by one pair of upper and lower installing plate 7, form crane span structure.Workpiece plate a plate moving mechanism 8 and workpiece plate b plate moving mechanism 5 and calibration disc plate moving mechanism 10 are located on 3 crossbeams 1 respectively.
Each workpiece plate plate moving mechanism is provided with workpiece plate driving mechanism.Workpiece plate 9 and workpiece plate 6 two workpiece plates under the driving of its driving mechanism, polishing disk 4 can move according to certain rules, and drive workpiece to move on polishing disk 4, realize processing the plane polishing of large-scale optical glass.
Calibration disc plate moving mechanism 10 is provided with the driving mechanism of calibration disc.Calibration disc 3 under the driving of its driving mechanism, polishing disk 4 can move according to certain rules, realizes the correction to polishing disk 4.
