SERVICE TOOL FOR CUTTING BIT ASSEMBLY

摘要

A tool includes an actuator assembly, a rod, a first nut, and a second nut. The actuator assembly includes a cylinder, a ram, and a bore extending through the cylinder and the ram. The cylinder includes an internal chamber supporting the ram, a first end, a second end, and a reaction surface positioned proximate the first end. The ram is movable relative to the cylinder and positioned adjacent the second end of the cylinder. The rod extends through the bore of the actuator assembly. The first nut is selectively coupled to one of a first end of the rod and a second end of the rod, and defines a first dimension larger than the bore width of the bit block. The second nut is selectively coupled to the other of the first end of the rod and the second end of the rod, and defines a second dimension less than the bore width.

1. A tool for installing and removing a bit sleeve with respect to a bore of a bit block, the bit sleeve including a shank and a bore for receiving a bit, the bit block bore defining a bore width, the tool comprising:
an actuator assembly including a cylinder and a ram, the cylinder including an internal chamber supporting the ram and configured to be in fluid communication with a fluid source, the cylinder including a first end, a second end, and a reaction surface positioned proximate the first end, the reaction surface configured to contact an end of the sleeve, the ram movable relative to the cylinder and positioned adjacent the second end of the cylinder, the actuator assembly including a bore extending through the cylinder and the ram; a rod including a first end and a second end, the rod defining a rod axis extending between the first end and the second end, the rod extending through the bore of the actuator assembly, a portion of the rod configured to extend through the bore of the bit sleeve such that the first end is positioned adjacent an end surface of the shank, the second end of the rod positioned adjacent the ram; a first nut selectively coupled to one of the first end of the rod and the second end of the rod, the first nut defining a first dimension configured to be larger than the bore width of the bit block; and a second nut selectively coupled to the other of the first end of the rod and the second end of the rod, the second nut defining a second dimension configured to be less than the bore width.
