Rotary impact device
View Patent ↗The present invention provides methods and systems for a rotary impact device having an annular exterior surface for use with an impact wrench for providing torque to a fastener. The rotary impact device includes an input member having an input recess for receiving the anvil of the impact wrench, an output member having an output recess for receiving the fastener, and an inertia member. The inertia member is stationary and positioned on the exterior surface of the rotary impact device for increasing the torque applied to the fastener.
1. An impact tool, comprising:
an impact tool that includes a rotary hammer and an anvil;
wherein the hammer impacts the anvil to rotate the anvil;
wherein the anvil extends outwardly from the hammer;
a socket that secures to the anvil opposite the hammer;
wherein the socket includes a body that extends between a first end and a second end:
wherein the first end includes a first opening having a first inner wall that extends inwardly from the first opening to define a square-shaped input recess that receives the anvil to secure to the anvil opposite the hammer;
wherein the second end includes a second opening and a second inner wall that extends inwardly from the second opening to define a hexagonal-shaped output recess configured to receive a head of a fastener;
wherein the body includes a cylindrical outer surface that defines a first radius;
wherein the body includes a disk positioned between the first end and the second end and a distance closer to the first end than to the second end;
wherein the disk defines a second radius that is greater than the first radius, wherein the disk includes at least two ribs extending outwardly from the cylindrical outer surface;
wherein a ring is secured to an outer radial end of each rib and is spaced apart from cylindrical outer surface;
wherein the disk remains stationary with respect to the body including the first end and the second end and located exterior of the impact tool.
2. The impact tool of claim 1 , wherein the body of the socket is formed as a single monolithic steel body.
3. The impact tool of claim 1 , wherein the ring has an inner surface that defines a third radius extending from the body, the third radius being greater than the first radius and less than the second radius.
4. An impact tool, comprising:
an impact tool that includes a rotary hammer and an anvil;
wherein the hammer impacts the anvil to rotate the anvil;
wherein the anvil extends outwardly from the hammer of the impact tool;
a socket that secures to the anvil opposite the hammer;
wherein the socket includes a body that extends between a first end and a second end, the body including:
wherein the first end includes a first opening having a first inner wall that extends inwardly from the first opening to define a square-shaped input recess that receives the anvil to secure to the anvil opposite the hammer;
wherein the second end includes a second opening and a second inner wall that extends inwardly from the second opening to define a hexagonal-shaped output recess configured to receive a head of a fastener;
wherein the body includes a cylindrical outer surface that defines a first radius;
wherein the body includes a disk positioned between the first end and the second end;
wherein the disk includes a first ring that extends transversely from the body to a second radius that is greater than the first radius of the outer surface of the body;
wherein the disk includes at least two ribs extending outwardly from the second radius of the first ring to a third radius;
wherein a second ring is secured to an outer radial end of each rib and is spaced apart from first ring.
