The present disclosure provides a deburring apparatus and a deburring method that does not require a positioning engagement part that is engaged with a fixed part of a machine tool. The deburring apparatus (10) includes a housing (1) with a shank (11), a transmission rod (3), a recovery rod (5), a tilting shaft (4), a spring (6), a holder (7), and a rotary-to-rectilinear motion conversion mechanism (9) with a plunger (8). The spring forces the recovery rod toward the tilting shaft. The holder for fixing the cutter (101) is arranged on the tilting shaft in a manner rotatable through a predetermined rotation angle. The rotary-to-rectilinear motion conversion mechanism separates the first flange portion from the second flange portion and brings the plunger into contact with the recovery rod on the tilting axis (43) when the holder rotates in a direction opposite to the rotation direction of the shank (11).

A rotary bit configured to deburr and swage an end of a tube, comprising a first end configured to deburr and swage the end of the tube, and a second end configured to be secured to a rotary device, wherein the first end includes a plurality of blades that extend axially along the first end and radially outward from the rotary bit, the plurality of blades including a plurality of leading blades and a plurality of finishing blades, the leading blades configured to initially deburr and swage the end of the tube upon insertion of the rotary bit into the end of the tube, and the finishing blades configured to complete deburring and swaging of the end of the tube, the finishing blades extending radially outward from the rotary bit to a greater extent than the leading blades.

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.

A chamfering tool 10 includes: a movable flange 5 having a cylindrical shape so that one end portion of a joint member 4 is inserted in the movable flange 5; a second spring member 6 configured to energize the movable flange 5 by one end portion of the second spring member 6; a spring receiver 7 to which the other end portion of the second spring member 6 abuts; a fixed flange 8 fixed to the other end portion of the joint member 4; and a chamfering member 9 fixed to the other end portion of the joint member 4, wherein the fixed flange 8 and the movable flange 5 have abutting surfaces formed by a flat surface, and an axial center of the chamfering member 9 substantially coincides with an axial center of the shaft member 2 when the abutting surfaces abut on each other.

A deburring method includes rotating a case, a sleeve and a drive gear together with a spindle of a machining tool; transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft; receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve; moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and cutting the workpiece by the tip tool.

A deburring tool includes: a case; a hollow sleeve that reciprocates inside the cylinder in a non-rotating manner; a drive gear disposed inside the sleeve, includes a first tooth, and rotates together with the case and the sleeve; a reciprocating shaft disposed inside the sleeve, including a driven gear disposed at a basal end portion of the sleeve and a basal end side of the drive gear, the driven gear including a second tooth, a tool holder disposed at a distal end portion of the sleeve, and slides inside the sleeve in a rotational and reciprocating direction, and a stem that fixes the driven gear and the tool holder, and penetrates the drive gear, a first spring that urges the sleeve toward distal end direction; and a second spring that urges the tool holder from the drive gear toward distal end direction.

An apparatus for selectively removing material from both an inner and outer circumference of an end of a tubular workpiece includes a cylindrical outer frame. A blade holder is affixed to the outer frame. The blade holder has a conical configuration with a base located adjacent a first rim of the outer frame and an apex located adjacent a second rim of the outer frame. At least one ID blade is carried by the blade holder and has an ID cutting edge oriented radially outward. At least one OD blade is carried by the blade holder and has an OD cutting edge oriented radially inward. A motive cap has a rim-coupling feature configured for selective engagement sequentially with the first and second rims of the outer frame, to selectively provide rotational motion to the outer frame and thus indirectly to the blade holder.

A rotary bit configured to deburr and swage an end of a tube, comprising a first end configured to deburr and swage the end of the tube, and a second end configured to be secured to a rotary device, wherein the first end includes a plurality of blades that extend axially along the first end and radially outward from the rotary bit, the plurality of blades including a plurality of leading blades and a plurality of finishing blades, the leading blades configured to initially deburr and swage the end of the tube upon insertion of the rotary bit into the end of the tube, and the finishing blades configured to complete deburring and swaging of the end of the tube, the finishing blades extending radially outward from the rotary bit to a greater extent than the leading blades.

A shaft deburring device includes a tubular metallic shaft having a drill mount at a first end and a deburring collar at a second end. The deburring collar has a plurality of radially disposed grinding balls secured about an interior surface of the collar. An exterior surface of the deburring collar has a plurality of radially disposed bristles.

A machine tool includes a first main shaft, a first drive source for moving the first main shaft, a second main shaft, a second drive source for moving the second main shaft, and a control means for carrying out a control so as to bring the workpiece held by the first main shaft and the workpiece held by the second main shaft into contact with each other while rotating them relative to each other, thereby to carry out the friction-heating, and to stop the relative rotation of the pair of workpieces and move only the second main shaft in the axial direction while holding the first main shaft stationary, thereby to carry out friction-welding of the pair of workpieces. The control means controls the operation of the first drive source upon the friction-welding of the pair of workpieces, so as to maintain the axial position of the first main shaft.
