Tool bracket and deburring tool having a tool bracket

Abstract

The present invention provides a tool bracket that allows the spindle body to tilt even when the moment load acting on the spindle body is relatively small. [Solution] The tool bracket 13 comprises a housing 14 having a cylinder chamber 15a extending in the direction of the cylinder axis 2, a piston 21 biased toward the tip by a compressible fluid and reciprocating within the cylinder chamber 15a, the piston 21 having an action part 21d positioned at the tip, a tilting body 17 having a tilting axis 3 and positioned within the cylinder chamber 15a and tiltable with respect to the cylinder axis 2, the tilting body 17 having a centering part 17a positioned at the base end and in contact with the action part 21d, a dog 33 positioned within the housing 14 and reciprocable along the direction of the cylinder axis 2, and a tilting sensor 35 for detecting the position of the dog 33.

Claims

1. A housing having a cylinder chamber extending in the direction of the cylinder axis, A piston that is biased toward the tip by a compressible fluid and reciprocates within the cylinder chamber, the piston having an action part located at the tip, A tilting body having a tilting axis, positioned within the cylinder chamber, and tiltable relative to the cylinder axis, the tilting body having a centering portion positioned at its base end and in contact with the working portion, A dog is disposed within the housing and is reciprocable along the axial direction of the cylinder, A tilt sensor for detecting the position of the dog, A tool bracket having

2. The centering portion is a convex spherical surface. The tool bracket according to claim 1.

3. The aforementioned working portion is a recess having a circular cross-section. The tool bracket according to claim 1 or 2.

4. Displaced in the housing and having an elastic body that biases the dog toward the tip, A tool bracket according to any one of claims 1 to 3.

5. The housing has a dog guide extending in the direction of the cylinder axis, The aforementioned dog is guided by the aforementioned dog guide, A tool bracket according to any one of claims 1 to 4.
