Connect, reinforcing pawl 7 is fixedly connected with piston 2, and load pawl 5 is in contact with reinforcing pawl 7.
During work, grinding head 16 etc. is installed on supporting cylinder 4, the force in radial such as grinding head 16（It is set to F1）So that supporting
Cylinder 4 swings amesiality around the center of rotation of universal bearing 3.Shaking moment M1=F1 × L1 caused by F1（L1 is the arm of force）.Gas
There is gas in chamber 8, piston 2 bears gas pressure（It is set to F2）, F2, which is passed to, to be reinforced pawl 7 and acts on load pawl 5, prevents supporting
Cylinder 4 is swung around the center of rotation of universal bearing 3.Moment of resistance M2=F2 × L2 caused by F2（L2 is the arm of force）.As M1=M2, float
Device stress balance, universal bearing 3 are not swung, now F1=F2 × L2/L1.During floating installation is swung, if swinging
Amplitude is little, and L1, L2 change are also little, and constant force floating is regarded as in engineering.Meanwhile by adjusting the air pressure in air cavity 8
Size also can adjusting means radial direction constant force size.
The utility model proposes radial direction constant force floating installation, polishing pressure can be made constant all the time, with realize constant force float
Polishing processing.It can absorb to hommization very much the path of machining and the curve deviation of processed blank material so that installation
Flexibly it can be operated in polishing device of the present utility model etc. along processed blank surface to realize the techniques such as polishing very much；
Meanwhile the utility model proposes radial direction constant force floating installation, when the air pressure in air cavity 8 is constant, radial load is constant all the time, does not have to

For measuring actual radial direction polishing power, monitoring can be used as to use, also can be by the data Real-time Feedback of measurement to outside control system
Unite and the air pressure in air cavity 8 is adjusted by external system.
Extending 12 and supporting cylinder 4 have certain gravity, and the utility model can be at different angles when specifically used
Use, therefore the gravity that extending 12 and supporting cylinder 4 have may be to supporting cylinder 4 and the thereon radial forces suffered by device
There is certain influence, i.e. these gravity may aggravate or offset certain radial load so that treat the radial load of polishing device
Size is not necessarily preferable, default size.In the utility model, the weight of structure formed by extending 12 and supporting cylinder 4
The center of rotation of the heart and universal bearing 3 overlaps, because extending 12 and supporting cylinder 4 are the center of rotation pendulum around universal bearing 3
Dynamic, therefore by this design, extending 12 and the gravity of supporting cylinder 4 can be caused to cancel each other, make up mutually, so as to eliminate
Influence of the gravity to radial load so that treat polishing device radial load size with it is default in the same size.Further, please
Reference picture 2, balancing weight 13 is provided with extending 12 to realize extending 12, supporting cylinder 4, balancing weight 13, force snesor 17
With grinding head 16 and be fixed on extending 12 and support center of gravity and the universal bearing 3 of structure formed by external devices on cylinder 4
Center of rotation overlap.In the specific implementation, it may be installed according to use demand on extending 12 or supporting cylinder 4, be fixed
There are external devices, such as power source, grinding head 16, the gravity that external devices carry may can also influence extending 12, supporting cylinder 4
And extending 12 and the center of gravity of structure formed by the device of the present utility model on supporting cylinder 4 and external devices are fixed on,
Therefore by adding balancing weight 13, come adjust extending 12, supporting cylinder 4, balancing weight 13, force snesor 17 and grinding head 16 and
The position of centre of gravity of structure, makes center of gravity and universal bearing 3 formed by external devices being fixed on extending 12 and supporting cylinder 4 etc.
Center of rotation overlaps.It is worth noting that, the position relationship and pattern of the balancing weight 13 shown in this preferred embodiment, only
It is a kind of preferable example, when it is implemented, can specifically be set according to specific service condition.
The utility model is mainly used in polishing, if universal bearing 3 can rotate, can influence effect of polishing.It please join
According to Fig. 1, limited block 14 is provided with universal bearing 3, limited block 14 causes universal bearing 3 to carry out the swing of radial direction, without
It can rotate to influence to polish.
Further, as shown in figure 1, the displacement that radial direction constant force floating installation also includes being used to measure the displacement of piston 2 passes
Sensor 15.Specifically, the one end of displacement transducer 15 is fixedly connected with cylinder barrel 1, the other end on piston 2 or piston 2 with fixing
The flat board of connection, flange etc. are fixedly connected or are flexibly connected.Assuming that the gas flow being filled with to air cavity 8 is certain, then the institute of piston 2
Stress is certain, therefore when the position for knowing piston 2（Displacement）, you can know the size of radial load.
Embodiment 2
Fig. 3 is refer to, as different from Example 1, in a preferred embodiment, one end inner sleeve of cylinder barrel 1 is provided with
Sleeve 10, sleeve 10 form air cavity 8 between cylinder barrel 1 and piston 2 between sleeve 10, cylinder barrel 1 and piston 2.Sleeve 10
Setting can both be advantageous to the machine-shaping of cylinder barrel 1, reduce the preparation difficulty of cylinder barrel 1, also help cylinder barrel 1 and living
The adjustment of plug 2, such as the adjustment of cylinder barrel 1 and the compactness of piston 2, the adjustment of cylinder barrel 1 and the interaction force of piston 2 and cylinder
The adjustment of cylinder 1 and 2 mutual movement relation of piston and the adjustment of structure, processability of cylinder barrel 1 etc..
Further, linear bearing 11 is provided between sleeve 10 and piston 2.It is universal when supporting cylinder 4 bears radial load
Bearing 3 is swung, and in the case where load pawl 5, reinforcing pawl 7 act on, piston 2 can impose certain side force to cylinder barrel 1 and sleeve 10, should
Side force and the mutual movement locus of piston 2 and sleeve 10 are simultaneously not parallel, therefore can easily to make between piston 2 and sleeve 10
Into abrasion, it is unfavorable for the use of device.Linear bearing 11 can be used for bearing side force, reduce between piston 2 and sleeve 10
Abrasion, beneficial to the mutual motion of piston 2 and sleeve 10.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
