Description
Technical field
The present invention relates to aspheric surface polishing devices, and in particular to a kind of passive strain disc burnishing device.
Background technique
Currently, aspheric surface polishing technology is mainly carried out using technologies such as active strain discs.And active strain disc polishing technology
COMPUTER DETECTION and pressure of the feedback control polishing disk each point in different location are needed, cost is too high.Common polishing disk does not have
The situation of change of pressure everywhere when method controls its polishing, so being difficult to obtain by way of machine polishing aspherical.Pure control by hand
The pressure change of polishing disk processed too, it is time-consuming and laborious, so aspheric surface polishing technology is always to be difficult to universalness at present.
Summary of the invention
In order to realize that machine fast polishing is aspherical, the present invention provides a kind of passive strain disc burnishing device.
A kind of passive strain disc burnishing device of the invention, including central axis, chassis, fixed bracket and several pressure are automatic
The bottom end of adjustable column, central axis is flexibly connected with chassis, and fixed bracket is fixedly connected with central axis, and several pressure automatically adjust column
Setting is on fixed bracket；Wherein, pressure automatic adjustment column includes outer sleeve, ball, column, spring, adjusting screw and limit
Ring, stop collar are arranged in outer sleeve bottom, and ball, column, spring, adjusting screw are successively set in outer sleeve, and ball is limited
System can move in stop collar and in stress, and the bottom of ball is contacted with the chassis, adjusting screw and outer sleeve
Top is connected through a screw thread.When in use, tray bottom is for being ground part to be thrown；When throwing part rotation, it will drive chassis
It rotates around center axis, chassis treats in rotation Shi Zehui and throws part one ablation power of generation；Because pressure automatically adjusts column point
For cloth on chassis, the height variation on chassis can force the telescopic spring in it, it is possible to perceive it by height variation
Lateral position, to apply a power related with position；The ablation power that this power makes chassis treat throwing part changes
Become, it is bigger closer to part edge to be thrown, it is more smaller by center, so the stock removal of edge is greater than at center, to realize
Aspherical polishing.
Preferably, the bottom end with chassis of the central axis are flexibly connected by universal joint.
It is furthermore preferred that the universal joint includes bulb and ball-and-socket, ball-and-socket is arranged on the chassis, and bulb setting exists
The bottom end of the central axis.Bulb is placed in the universal connection that central axis and chassis can be realized within ball-and-socket.
Preferably, the quantity of pressure automatic adjustment column can be four, eight or 12.Pressure automatic adjustment
Column is distributed around even circumferential, and it is best theoretically, on chassis to be covered with this pressure automatic adjustment column effect.
Preferably, the material of the ball is steel.
Beneficial effects of the present invention: different from active stress disk technology, passive strain disc burnishing device of the invention passes through
Spring automatic adjustment in pressure automatic adjustment column polishes the pressure of disk each point at different locations to realize aspheric surface polishing；
Change pressure at strain disc different location loads automatically, does not need to recycle computer to control pressure by position detection
Size.

Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of passive strain disc burnishing device of the invention, if including central axis 100, fixed bracket 200,
Dry-pressing power automatically adjusts column 300 and chassis 400.Chassis 400 can be polishing disk common in the art, during top surface has
Heart hole, centre bore is interior to be equipped with ball-and-socket, and 100 bottom end of central axis is equipped with bulb, and the bulb is inserted among ball-and-socket, so that chassis 400
It can be freely rotated around central axis 100.In the present embodiment, bulb and ball-and-socket constitute universal joint；In other embodiments, may be used
Using the universal joint of other forms.Fixed bracket 200 is the diameter circular piece equal with chassis 400, is offered in thereon
The matched centre bore of mandrel 100, is set on central axis 100 by the centre bore；It is additionally provided with thereon and automatically adjusts column with pressure
300 matched mounting holes, pressure automatic adjustment column 300 are inserted into the mounting hole, and the corresponding pressure of each mounting hole is automatic
Adjustable column 300.In Fig. 1, it is shown that nine pressure automatically adjust column 300, they are evenly distributed on fixed bracket 200.
As shown in Fig. 2, pressure automatic adjustment column 300 includes outer sleeve 302, ball 305, column 304, spring 303, adjusts
Screw 301 and stop collar 306.Outer sleeve 302 is hollow, and stop collar 306 is arranged in 302 bottom of outer sleeve, ball 305, column
304, spring 303 and adjusting screw 301 are successively set in outer sleeve 302 by sequence from the bottom up.Ball 305 is steel ball,
It is limited on stop collar 306, stop collar 306 is stretched out in the bottom of ball 305, which contacts with the top on chassis 400.
It when extruding of the ball 305 by chassis 400, can move upwards, to push column 304, spring 303 be forced to shrink.It adjusts
Screw 301 is connect by screw thread with the top of outer sleeve 302, by rotating adjusting screw 301, is capable of the first of adjustment spring 303
Beginning telescopic level.
Different from active stress disk technology, each point pressure changes with position on the passive strain disc burnishing device
Passive stress variation.Fig. 3 shows the working principle of the passive strain disc burnishing device, which is covered with pressure
Column is automatically adjusted, it can perceive its lateral position by height variation, to apply a power related with position.Therefore,
A bigger power, and center can be applied to the polishing disk of bottom in the pressure adjustable column wait throw aspherical (part to be thrown) edge
Place then applies a small power.Therefore, when throwing aspherical rotation, it will drive polishing chassis to rotate, and polishing disk is rotating
Shi Zehui to it is polished it is aspherical have an ablation power, the active force is bigger closer to part edge to be thrown, more by center more
It is small, so the stock removal of edge is greater than at center, to realize aspherical polishing.Variation at strain disc different location
Pressure loads automatically, does not need to recycle computer to control pressure size by position detection.
Above-mentioned is the preferable embodiment of the present invention, but embodiments of the present invention are not limited by the foregoing content,
His any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention, should be
The substitute mode of effect, is included within the scope of the present invention.
