Abstract
Official abstract text for this publication.
Provided is a tool bracket capable of tilting a spindle body even when a moment load acting on the spindle body is relatively small. A tool bracket includes: a housing including a cylinder chamber extending along a cylinder axis; a piston urged by compressible fluid toward distal end to reciprocate in the cylinder chamber and having an action portion disposed at distal end; and a tilting body having a tilt axis and disposed in the cylinder chamber in a tiltable manner with respect to the cylinder axis, and includes a centering portion disposed at basal end to abut the action portion, the centering portion presses the piston with the cylinder axis as an action line when the tilt axis is tilted from the cylinder axis.
First claim
Opening claim text (preview).
What is claimed is: 1 . A tool bracket, comprising: a housing including a cylinder chamber extending along a cylinder axis; a piston configured to be urged by compressible fluid toward distal end to reciprocate in the cylinder chamber, the piston having an action portion disposed at a distal end of the piston; and a tilting body having a tilt axis, the tilting body disposed in the cylinder chamber in a tiltable manner with respect to the cylinder axis, the tilting body including a centering portion disposed at basal end to abut the action portion, the centering portion configured to press the piston with the cylinder axis as an action line when the tilt axis is tilted from the cylinder axis. 2 . The tool bracket according to claim 1 , wherein the centering portion has a convex spherical surface. 3 . The tool bracket according to claim 1 , wherein the action portion is a recess having a circular cross-section. 4 . The tool bracket according to claim 1 , wherein the centering portion includes a plurality of contact protrusions arranged n-times symmetrically about the tilt axis, n is an integer of 3 or more, and the action portion is a concave spherical surface having a center on the cylinder axis. 5 . The tool bracket according to claim 1 , wherein the housing includes a seat surface disposed at distal end, the tilting body includes a head surface disposed at distal end, the head surface abuts against the seat surface when the tilt axis is substantially aligned with the cylinder axis. 6 . The tool bracket according to claim 1 , wherein the seat surface is a flat plane perpendicular to the cylinder axis, and the head surface is a flat plane perpendicular to the tilt axis. 7 . The tool bracket according to claim 1 , wherein a spindle body is attached to the tilting body, a rotatable tip tool is attachable to the spindle body, the tool bracket further comprises: a rotation stopper disposed between the tilting body and the housing to prevent the tilting body from rotating about the cylinder axis. 8 . The tool bracket according to claim 7 , wherein the rotation stopper is disposed in the cylinder chamber near the distal end. 9 . A deburring tool, comprising: the tool bracket according to claim 1 , and a spindle body to which a rotatable tip tool is attachable, the spindle body disposed on the tilting body to be tilted integrally with the tilting body. 10 . The tool bracket according to claim 2 , wherein the action portion is a recess having a circular cross-section. 11 . The tool bracket according to claim 3 , wherein the centering portion includes a plurality of contact protrusions arranged n-times symmetrically about the tilt axis, n is an integer of 3 or more, and the action portion is a concave spherical surface having a center on the cylinder axis. 12 . The tool bracket according to claim 2 , wherein the housing includes a seat surface disposed at distal end, the tilting body includes a head surface disposed at distal end, the head surface abuts against the seat surface when the tilt axis is substantially aligned with the cylinder axis. 13 . The tool bracket according to claim 3 , wherein the housing includes a seat surface disposed at distal end, the tilting body includes a head surface disposed at distal end, the head surface abuts against the seat surface when the tilt axis is substantially aligned with the cylinder axis. 14 . The tool bracket according to claim 4 , wherein the housing includes a seat surface disposed at distal end, the tilting body includes a head surface disposed at distal end, the head surface abuts against the seat surface when the tilt axis is substantially aligned with the cylinder axis. 15 . The tool bracket according to claim 2 , wherein the seat surface is a flat plane perpendicular to the cylinder axis, and the head surface is a flat plane perpendicular to the tilt axis. 16 . The tool bracket according to claim 3 , wherein the seat surface is a flat plane perpendicular to the cylinder axis, and the head surface is a flat plane perpendicular to the tilt axis. 17 . The tool bracket according to claim 4 , wherein the seat surface is a flat plane perpendicular to the cylinder axis, and the head surface is a flat plane perpendicular to the tilt axis. 18 . The tool bracket according to claim 5 , wherein the seat surface is a flat plane perpendicular to the cylinder axis, and the head surface is a flat plane perpendicular to the tilt axis.
