摘要： In an example, a system is disclosed. The system comprises a one-piece mandrel, a fuselage coupled to the one-piece mandrel, and a strongback apparatus positioned on the fuselage. The strongback apparatus comprises an arcuate central body comprising a front end, a rear end, and a plurality of elongated members that connect the front end to the rear end, and actuators mounted to the plurality of elongated members. The actuators are configured to move in a radially outward direction from extended positions to retracted positions and comprise (i) proximal ends mounted to the plurality of elongated members and (ii) distal ends having vacuum suction cups. In the extended positions, the vacuum suction cups engage the fuselage on which the strongback apparatus is positioned. As the actuators moves from the extended positions to the retracted positions, the vacuum suction cups pull the fuselage away from the one-piece mandrel.

摘要： The present disclosure provides a spindle structure including a base, a spindle, a sliding member, a restoring mechanism, and a restriction member. The spindle is rotatably received in the base and forms a receiving room. An end of the receiving room is a blind end communicating exterior via a gas channel. The sliding member is slidably received in the receiving room, and two ends thereof are a piston and a driving portion respectively. A gas cavity is defined between the piston and the blind end. The sliding member tends to move toward the blind end due to the restoring mechanism. The restriction member is connected to the driving portion and radially deforms when the sliding member slides so as to fix or to release the tool-holder. The sliding member slides outward when the gas cavity is injected with gas via the gas channel.

摘要： Provided is a rotary tool with a compact tip tool holding portion (80). The rotary tool is provided with a sleeve (81) attached to an output shaft (41) to switch a tip tool (70) between a fixed state and a detachable state. The output shaft (41) has a through hole (46) formed therein radially penetrating from the inside to the outside of a mounting hole thereof. The through hole (46) has a steel ball (85) provided therein such that at least a part of the steel ball (85) overlaps at least a part of a case (10). The sleeve (81) defines a first position in the outward direction of the steel ball (85), while the case (10) regulates a second position on the radially outer side of the first position.

摘要： An arbor for a hole saw an arbor stem, an actuator, and at least one post. The arbor stem includes at least one arm having a threaded portion configured to engage the hole saw. The actuator is rotatable about a central axis of the arbor to move the at least one arm. The actuator includes a surface facing the at least one arm and a track. The track is recessed from the surface of the actuator. The at least one post extends from the at least one arm to engage the track. The arm is movable in a radial direction in response to rotation of the actuator to vary a circumference of the arbor stem.

摘要： Disclosed is an assembling and centering structure for a processing tool, the structure having a clamping handle (10), a processing head (20), and a fastening member (30) for connecting and fixing the clamping handle (10) and the processing head (20). An end face accommodation groove (100) of the clamping handle (10) is formed with a concave part (11) and a centering hole (12). The processing head (20) is formed with a convex part (211) and a centering post (222), the convex part (211) matches the concave part (11), and the centering post (222) matches the centering hole (12). Thus, it can be ensured that after assembly, the central axis of rotation of the clamping handle (10) is in a straight line with the central axis of rotation of the processing head (20).

摘要： A machine tool (1) removes chips adhering to a working portion of a tool (T). More specifically, a fluid injecting nozzle (23, 24) injects a fluid toward the tool (T) enclosed in an enclosure (22). A controller (15) controls a position of the tool (T) within the enclosure (22), and further controls operation of the fluid injecting nozzle (23, 24) such that the fluid is injected when the tool (T) is within the enclosure (22).
