Rotary chuck

A rotary chuck includes a clamp assembly, a first drive mechanism for operating the clamp assembly to clamp an associated workpiece, a frame rotationally fixed to the clamp assembly, and a second drive mechanism for rotating the frame and the clamp assembly. The second drive mechanism can rotate the frame and the clamp assembly around 360 degrees. A pair of alignment springs are engaged with a mounting plate upon which the second drive mechanism is mounted. The mounting plate can pivot relative to a stable surface to which it is mounted, and the springs limit the pivotal movement. Each first and second drive mechanism includes a motor, and are connected to a microprocessor for operation of the respective motor.

Induction heating coil, and an apparatus and method for manufacturing a worked member

An induction heating coil for stably heating a steel tube which is being fed in its axial direction without rotating, the heating being uniform in the circumferential direction and in a narrow range in the axial direction has at least two 1-turn coils in the form of a first turn coil body and a second turn coil body. The inner peripheral length Ln (the non-effective coil length) where the effective number of coil turns is less than the total number of coil turns when the coil is projected in the axial direction and the inner peripheral length L0 of the projected coil bodies (the inner coil length) satisfy Ln/L0<0.05. First and second coil bodies have insulating portions on their connecting portions, and the insulating portions are present in locations separated by a central angle of 5-45 measured from the center of the coil bodies.

Pipe bender alignment assembly
12409484 · 2025-09-09 ·

A pipe bender alignment assembly includes a sleeve that is positionable around a pipe. A plurality of laser mounts is each attached to and extends outwardly from the sleeve and a plurality of laser emitters is mounted to a respective one of the plurality of laser mounts to emit a beam of laser light outwardly from the sleeve. The sleeve is rotatable on the pipe to align a respective one of the plurality of laser emitters with an alignment mark on a pipe bender to visually indicate that the pipe is precisely located in the pipe bender for accurately bending the pipe. A magnet is integrated into the sleeve for retaining the sleeve at a particular angle of rotating on the pipe.
