Abstract
The utility model relates to a fine-lapping polishing machine of quasi-spherical center. The fine-lapping polishing machine of quasi-spherical center comprises a pendulum shaft, a swing arm, a pressure shaft, a mold joint, a lapping sphere, and a main shaft, wherein the swing arm and the main shaft are arranged in the same plane; the pressure shaft sways back and forth in a plane vertical to the plane of the swing arm and the main shaft; the main shaft and the pendulum shaft pass through the center of the same lapping sphere; and the pressure shaft is arranged in a direction deflected to the center of the lapping sphere by a variable quantity. Compared with the prior art, the utility model has stable operation process and high processing accuracy and efficiency.
Description
Technical field
The utility model relates to optics cold working equipment, relates in particular to a kind of quasi-spherical center fine grinding polishing machine.
Background technology
Traditional accurate centre of sphere polissoir possesses following feature: 1, balance staff and main shaft are in same plane; 2, pressure axis swings back and forth through in the plane of main-shaft axis simultaneously on the plane perpendicular to balance staff; 3, main shaft, pressure axis and balance staff are crossed same point (the abrading-ball centre of sphere), the i.e. notion of the accurate centre of sphere (as shown in Figure 1).The power that plays a major role for the grinding of part to be processed is radial load F, and the structure of above-mentioned polissoir can make the pressure size evenly, but this structure does not have the influence (as shown in Figure 2) of fine consideration swing thrust R to processing.R is vertical with connector mold for swing thrust, the moment that produces can make the connector mold overturning, though can reduce its influence by the force choose reasonable, but can impact, particularly be easy to generate vibrations, make the stressed shakiness of workpiece, and then influence part processing precision in the moment that swing is turned one's head, reduce production efficiency, can obviously reduce the equipment range of work simultaneously.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of process steadily, part processing precision and the high quasi-spherical center fine grinding polishing machine of working (machining) efficiency.
The purpose of this utility model can be achieved through the following technical solutions: a kind of quasi-spherical center fine grinding polishing machine, comprise balance staff, swing arm, pressure axis, connector mold, abrading-ball, main shaft, described balance staff and main shaft are in same plane, described pressure axis is swinging back and forth perpendicular to above-mentioned balance staff and main shaft plane, and described main shaft, balance staff are crossed the same abrading-ball centre of sphere; It is characterized in that described pressure axis departs from the setting of the abrading-ball centre of sphere, and bias is adjustable.
Described pressure axis, connector mold and main shaft are three sections broken line structures in same plane.
Described pressure axis swings back and forth on the plane perpendicular to three sections broken lines.
Produce twisting between two joinings of described three sections broken lines.
The utility model provides a kind of brand-new technology solution at the deficiency and the defective of present domestic accurate centre of sphere class cold machining machine tool,, keeps the design that original main shaft and balance staff all pass through the centre of sphere that is, and uniformity consistency keep-ups pressure.Change the pressure axis design, make it to depart from the centre of sphere, and bias is adjustable, to be fit to the needs of dissimilar parts.Pressure axis, connector mold and main shaft become three sections broken lines (as shown in Figure 3) in a plane like this, when pressure axis is done swing perpendicular to this plane, will produce twisting between three-way two joinings, and the major part influence of swinging thrust R has been offset in this twisting just, make in the part processing process more steadily, obviously improved part processing precision and working (machining) efficiency.The utility model is not having big variation for cold working equipment aspect volume, the weight, but it is good to improve rear stability.
The utility model is the designer through for many years to putting forward after the cold worked mechanical analysis of optics, having changed both at home and abroad technology prejudice to this kind equipment, (main shaft, pressure axis and balance staff must be crossed same centre of sphere point, and to must be accurate more, precision is high more), greatly facilitate the user, improved machining accuracy and service efficiency.

Fig. 1 is the structural representation of traditional quasi-spherical center fine grinding polishing machine;
Fig. 2 is that the A of Fig. 1 is to structural representation;
Fig. 3 is the structural representation of the utility model quasi-spherical center fine grinding polishing machine;
Fig. 4 is that the B of Fig. 3 is to structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Embodiment
As shown in Figure 3, Figure 4, a kind of quasi-spherical center fine grinding polishing machine, comprise balance staff 1, swing arm 2, pressure axis 3, connector mold 4, abrading-ball 5, main shaft 6, described balance staff 1 and main shaft 6 are in same plane, described pressure axis 3 is swinging back and forth perpendicular to above-mentioned balance staff and main shaft plane, described main shaft 6, balance staff 1 are crossed the same abrading-ball centre of sphere 51, and described pressure axis 3 departs from the abrading-ball centre of sphere 51 and is provided with, and bias h can regulate according to the size of part to be processed 7; Described pressure axis 3, connector mold 4 and main shaft 6 are three sections broken line structures in same plane; Described pressure axis 3 swings back and forth on the plane perpendicular to three sections broken lines; Produce twisting between two joining a, the b of described three sections broken lines when above-mentioned pressure axis 3 swings back and forth, the major part influence of swing thrust R has been offset in this twisting, makes in the part processing process more steady.
The improved quasi-spherical center fine grinding polissoir of the utility model is simple in structure, easy to operate, compared with prior art, have substantial characteristics and obvious improvement, the present optical device of China is the foreign imitation device fabrication mostly, and the utility model will really change the present situation that Chinese do not have the independent intellectual property right optical device.
