Apparatuses and methods of operating a linear differential (100, 600) are described herein. The linear differential (100, 600) contains a slide portion (102) with parallel right-hand and left-hand threaded rods (112, 114). Threaded onto the right-hand and left-hand threaded rods (112, 114) and attached to the slide portion (102) are right-hand and left-hand gears (116, 118). Meshed between the right-hand and left-hand gears (116, 118) and also attached to the slide portion (102) is a driven gear (200). An end effector (104) is attached to the driven gear (200) and is configured to translate along a translation axis (110) and rotate around a rotation axis (120).

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 power tool is advantageously configured to provide a rotating motion, an oscillating motion, and a reciprocating motion. The power tool includes at least one motor, which is operable to drive these three different motions at the same time. The power tool includes a rotating member, which is configured to output a rotating motion. The rotating member is configured to attach to and detach from a rotating accessory. The power tool includes an oscillating member, which is configured to output an oscillating motion. The oscillating member is configured to attach to and detach from an oscillating accessory. The power tool includes a pin, which is configured to output a reciprocating motion. The pin is configured to provide the reciprocating motion to a reciprocating accessory. The power tool is configured to provide a connected accessory with the corresponding motion during operation.

Driving systems for tools used with metal-fabricating presses or other machines, whereby planetary gears are used in the systems, and whereby the driving systems can be constructed for use with particular tooling, such as tapping tools, and complementary systems can be exemplarily configured for use with such driving systems. The driving systems can enable enhanced tool output as compared to conventional driving mechanisms, while also enabling variable disassembly and configuration of the systems relative to the intended machining operations.

A rotary type linear reciprocating motion device includes: a driving part rotatably driven by a motor; a rotating part installed at one surface of the driving part, the rotating part transferring a rotational force of the driving part to an applicator; and a reciprocating part installed at the other surface of the driving part, the reciprocating part converting the rotational force of the driving part into a linear reciprocating motion force, the reciprocating part transferring the linear reciprocating motion force to the applicator. The driving part includes: a driving plate having both surfaces at which the rotating part and the reciprocating part are respectively installed; and a driving belt installed at an edge of the driving plate, the driving belt being in contact with a motor shaft of the motor to allow a driving force of the motor to be transferred to the driving plate by a frictional force.
