Title:
LOCKING SYSTEM TO PREVENT ROTATION OF TOOLHOLDER
Document Type and Number:
WIPO Patent Application WO/2017/165593
Kind Code:
A3
Abstract:
A mounting block assembly (118) and method for assembling is disclosed. The mounting block assembly (118) may comprise a mounting block (128) and a toolholder (130). The mounting block may include a flighting portion (134), a mounting portion (136) and a protrusion (138). The mounting portion (136) defines a first bore (144) that is configured to receive a toolholder (130). The toolholder includes a generally cylindrical sidewall (146) that defines an axis (X) and defines a second bore (148) that is configured to receive a stem (150) of a cutting bit (132). The sidewall (146) includes a pair of radially outward extending prongs (152) that define a first recess (154) between the prongs (152). The first recess (154) is configured to interlockably receive the protrusion (138) when the toolholder (130) is disposed in the mounting portion (136), wherein the interlocked configuration of the toolholder (130) and the mounting block (128) inhibit rotational movement of the toolholder (130) about the axis (X).
