Tool assembly and related methods

Abstract

A tool assembly for a rotary hammer is provided. The tool assembly includes an adapter and a drive socket removably mounted on the adapter. The adapter has a first end portion configured to be held by a chuck of the rotary hammer and a second end portion that includes a socket square drive fitting on which the drive socket is removably mounted. The socket drive fitting can have any suitable size. For example, the socket drive fitting can be a ¼ inch, a ⅜ inch, a ½ inch, or a ¾ inch square drive fitting.

1 . A tool assembly for a rotary hammer, the tool assembly comprising:
 an adapter having a first end portion and a second end portion opposite the first end portion, the first end portion configured to be held by a chuck of the rotary hammer, the second end portion comprising a socket square drive fitting; and   a drive socket removably mounted on the adapter via the socket square drive fitting.   
     
     
         2 . The tool assembly of  claim 1 , wherein the adapter is configured to transfer an axial compression force from the rotary hammer to the socket, the axial compression force oriented along a direction from the first end portion to the second end portion. 
     
     
         3 . The tool assembly of  claim 2 , wherein the second end portion comprises external surfaces shaped to substantially prevent relative axial movement between the adapter and the socket along the direction from the first end portion to the second end portion so as to transfer the axial compression force from the adapter to the socket. 
     
     
         4 . The tool assembly of  claim 1 , wherein the adapter has an elongate body between the first and second end portions, the elongate body oriented along an elongate axis of the adapter and comprising an external surface disposed between the first and second end portions that is configured to be held by an operator of the rotary hammer during use. 
     
     
         5 . The tool assembly of  claim 4 , wherein the external surface comprises an axial-symmetric surface with a maximum diameter of between 1.0 to 2.5 inches. 
     
     
         6 . The tool assembly of  claim 5 , wherein the external surface comprises a cylindrical surface. 
     
     
         7 . The tool assembly of  claim 1 , wherein the first end portion comprises an elongated cylindrical body having one or more elongated recesses configured to be held by the chuck so as to substantially prevent relative rotational movement between the adapter and the chuck. 
     
     
         8 . The tool assembly of  claim 7 , wherein the one or more elongated recesses comprise a recess that extends to the end of the first end portion. 
     
     
         9 . The tool assembly of  claim 8 , wherein the one or more elongated recesses further comprises a recess that does not extend to the end of the first end portion. 
     
     
         10 . The tool assembly of  claim 7 , wherein the one or more elongated recesses comprises a recess that does not extend to the end of the first end portion. 
     
     
         11 . The tool assembly of  claim 1 , wherein the socket drive fitting is a ¼ inch, a ⅜ inch, a ½ inch, or a ¾ inch square drive fitting. 
     
     
         12 . A method for installing an anchor bolt, the method comprising:
 mounting an adapter fitting having a socket square drive fitting to a chuck of a rotary hammer;   mounting a drive socket to the socket square drive fitting;   engaging the anchor bolt with the drive socket;   driving the anchor bolt into a mounting hole by driving the adapter fitting and the drive socket with the rotary hammer operating in an axial hammering mode; and   rotating the adapter fitting and the drive socket with the rotary hammer operating in a rotation mode so as to secure the anchor bolt within the mounting hole.   
     
     
         13 . The method of  claim 12 , further comprising constraining the adapter during the driving of the anchor bolt into the mounting hole by a person holding the adapter. 
     
     
         14 . A method for removing a fastening component, the method comprising:
 engaging a drive socket with a nut or a fastener head; and   simultaneously,
 imparting a sequence of axial impacts onto the nut or the fastener head from the drive socket along an axis of rotation of the nut or the fastener head, and 
 imparting a sequence of torque impulses onto the nut or the fastener head from the drive socket about an axis of rotation of the nut or the fastener head. 
   
     
     
         15 . The method of  claim 14 , further comprising coupling the drive socket with a rotary power tool operable to simultaneously impart the sequence of axial impacts and the sequence of torque impulses to the drive socket. 
     
     
         16 . The method of  claim 14 , further comprising:
 mounting an adapter fitting having a socket square drive fitting to a chuck of a rotary power tool operable to simultaneously impart the sequence of axial impacts and the sequence of torque impulses to the adapter fitting; and   mounting the drive socket to the adapter fitting via the socket square drive fitting.   
     
     
         17 . The method of  claim 14 , wherein the sequence of axial impacts and the sequence of torque impulses are in phase. 
     
     
         18 . The method of  claim 14 , wherein the sequence of axial impacts and the sequence of torque impulses are out of phase. 
     
     
         19 . The method of  claim 14 , wherein the sequence of axial impacts and the sequence of torque impulses have different frequencies.
