Abstract
A quick change mounting system for grinding and other surface preparation pads provides a simple and effective way for the pads to be mounted and changed on the mounting plate of a large surface preparation machine without removing the mounting plate from the machine. (This method also allows that existing mounting plates and preparation pads may be used with a minimal amount of adaptation.) The new quick-change system makes use of a unique slot design (using countersunk keyhole slots) for mounting the pads on the plate. Studs fixed on the pads fit into slots on the plate and may lock into position. In operation, centrifugal and other forces then help to further seat the pad onto the plate.
Claims20
A quick-change system for surface preparation equipment comprising:
- a mounting plate with a front side and a back side, said mounting plate having at least one installation station adapted for receiving a preparation pad, said at least one installation station consisting of at least one keyhole slot, and said preparation pad having at least one protruding stud fitted into said at least one keyhole slot, such that said preparation pad fits snugly against said front side of said mounting plate.
A quick-change system adapted to be used on an existing mounting plate having at least one installation station, wherein said at least one installation station comprises three holes through said mounting plate, said system comprising an adapter pad with at least one keyhole slot to be installed onto said mounting plate by screwing onto said mounting plate through said three holes and a preparation pad to be removably mounted onto said adapter pad using said at least one keyhole slot.
A method of temporarily installing a preparation pad onto a mounting plate of a surface preparation machine, said mounting plate defining at least one keyhole slot and said preparation pad comprising at least one protruding stud designed to mate therein, said method comprising the steps of:
- selecting an appropriate preparation pad according to the surface preparation task to be performed;
- aligning the at least one protruding stud of the preparation pad with the keyhole slot of the mounting plate;
- and inserting said protruding stud into said keyhole slot by pushing and sliding and engaging therein.
