Abstract
The device for mounting and removal of polishing wheels comprises a cup-shaped support of partially elastic material and fitted on the mounting face of a polishing wheel. A receiving plate is forcibly engaged within the support by elastic deformation of the cup and rigidly fixed to the end of a driving shaft. A duct formed in the bottom wall of the cup serves to discharge air at the time of assembly or to blow-in compressed air between the cup and the receiving plate for subsequent uncoupling of these two components and removal of the corresponding polishing wheel.
Claims13
A device for mounting and removal of polishing wheels carried by rotary shafts of the polishing head of a polishing machine by means of two coupling members provided respectively on the free ends of said rotary shafts and on the coupling faces of said polishing wheels, the first coupling member being designed in the form of a disk or plate having a frusto-conical external wall whilst the second coupling member is adapted to clamp the external wall of said plate, wherein:
- the second coupling member is formed of material which is at least partly elastic and is designed in the shape of a cup having a frusto-conical internal wall similar in profile to the external wall of the plate which constitutes said first coupling member ;
- the bottom wall of said cup-shaped member is provided with:
- a bore through which air is discharged at the time of forcible assembly of the two coupling members and through which air under pressure is blown-in between said members in order to separate these latter ;
- a recess for constituting a pressure chamber at the time of blowing of air under pressure through the bore for the purpose of separating said two coupling members.
