Abstract

A clamping assembly for clamping a block of wearable material for guiding a band saw blade to maintain the blade in alignment at a working station. The block of wearable material is formed with a dovetail adjacent a rear face remote from the wearing face of the block, and the clamping assembly includes clamping elements having inclined surfaces mating with the inclined surfaces of the dovetail to provide clamping and gripping forces and inwardly directed drawing forces on the block. The clamping elements are separated in the clamping region by a gap permitting them to be drawn towards one another and thereby to exert a clamping force on the dovetail of the block of wearable material. The clamping elements are dimensioned so that one element behaves as a cantilever spaced from the other element, which thereby maintains a fixed relationship with a supporting datum surface.

Dependent claims

A clamping assembly for clamping a guide block of wearable material therein, the block having first and second engaging surfaces adjacent an inner face thereof, and an outer face remote from the inner face to serve as a wearing surface to bear against a wearing element of a machine, the clamping assembly and block being received in a holding means of the machine for location adjacent a machine datum surface, the clamping assembly being characterized by:

(a) a first clamping element having front and rear portions, the front portion having a first gripping and bearing surface for engaging the first engaging surface of the block,
(b) a second clamping element having front and rear portions, the front portion having a second gripping and bearing surface for engaging the second engaging surface of the block,
(c) spacer means cooperating with the respective rear portions of the first and second clamping elements to maintain a gap between portions of the clamping elements,
(d) complementary alignment means adjacent the spacer means and cooperating with the first and second clamping elements to maintain the clamping elements in alignment with each other and with the block,
(e) clamp means disposed remotely from the spacer means for applying a clamping force to the clamping elements and thence to the block so that the force deflects the second clamping element toward the first clamping element to narrow the gap therebetween.
