The invention provides an oval ultrasonic machining device with a non-contact induction power supply function. The oval ultrasonic machining device is composed of an induction power supply device and an oval ultrasonic tool handle. The induction power supply vice sides of the induction power supply device are fixed to a BT tool handle shell of the oval ultrasonic tool handle. The induction power supply primary sides of the induction power supply device are arranged on the outer side of the oval ultrasonic tool handle and are arranged in an internal-external concentric circle mode. The gap between the two induction power supply primary sides is kept small. The induction power supply primary sides are fixed to a spindle seat of a numerical control machining center machine tool through a bracket and kept static. The oval ultrasonic tool handle is fixed a spindle of the numerical control machining center spindle through a taper shank and rotates at a high speed along with the spindle. By adoption of the oval ultrasonic machining device, the rotary radius of the oval ultrasonic tool handle is decreased, the rotary inertia of the oval ultrasonic tool handle is lowered, rotary stability of the oval ultrasonic tool handle is improved, and the oval ultrasonic machining device can avoid the working space of a tool replacing manipulator and meet the automatic tool replacing condition under the condition that the structure of the spindle of the numerical control machining machine tool is not changed. The structure is simple, and operation and use are convenient.

The helix heated hoses 10 and 12 use two features to increase the flexibility. The first feature is a braided-copper heating element 14, which has increased flexibility over the prior art solid copper heating element. The element is spiral wound around the hose and held in place with a moisture barrier 16. The second feature is the helix twist 18 located just before the point where the hoses 10 and 12 attach to the manifold 20. The helix feature is created with the helix support 22, which initiates the twist around 24 inches back from the point of termination. The helix feature works to reduce the moment of inertia about the neutral axis 26 of the two supply hoses 10 and 12.

The latch needle (1) of the invention has a latch (7), which is provided on its free end, on its side facing away from the hook (3), with one or more recesses (18, 19). The function of these recesses is to reduce the moment of inertia of the latch (7), which leads to an increased service life of the latch. Between the recesses (18, 19), a rib remains, whose top side functions like a skid for loops to be transferred. The indentations (18, 19) are preferably elongated depressions. However, corresponding openings may be provided as a substitute instead.

A driving device which makes it possible to reduce the moment of inertia of a rotor and increase torque. A magnet is formed to have a hollow cylindrical shape and has magnetized sections which are magnetized to have alternately different poles in a circumferential direction thereof. A coil is wound coaxially with the magnet and is disposed in axially side-by-side relation to the magnet. A stator yoke is formed of a soft magnetic material and fixes the magnet and the coil. A rotor yoke is formed of a soft magnetic material, and has magnetic pole portions formed in opposed relation to the magnetized sections, for being magnetized by the coil. The rotor yoke is supported in a manner rotatable with respect to the stator yoke. An rotation restricting part limits a range of rotation of the rotor yoke within a predetermined angle.

An automated assembly apparatus comprises an assembly robot that includes a Y-axis movement unit, a first X-axis movement unit movable in a Y-axis direction along the Y-axis movement unit, and a grip unit movable in an X-axis direction along the X-axis movement unit, and a workbench unit including a Z-axis movement unit arranged below the assembly robot with respect to an Z-axis and a workbench movable in the Z-axis direction along the Z-axis movement unit, wherein an assembly operation for a first assembly component gripped by the grip unit and a second assembly component mounted on the workbench unit is performed through movement in the Z-axis direction by the workbench unit.

A robot quick-release assembly has a first joint member and a robot component mounted thereon, the first joint member has a first coupler and a second joint member, a robot arm mounted thereon has a second coupler, a clamp, and a locking collar. The first coupler can be coaxially aligned with the second coupler and pressed into the second joint member, and detachably connected to the second joint member. The first mechanical coupler is detachably connected to the second mechanical coupler for transferring power across the quick-release assembly. The robot component can receive an additional electrical connector, the additional electrical connector supplying power to the robot component. The quick-release assembly coupling assembly further exerts large forces with the application of a relatively small torque to the locking collar by applying a two stage wedge engagement and can further include a sequencing system.

The invention discloses a non-contact inductive power supply device for ultrasonic milling, which mainly includes a primary side and a secondary side. The spatial position relationship between the primary side and the secondary side is arranged as an inner and outer concentric circle, and there is no mechanical connection between the two, wherein the structure of the primary side is only about 2 / 5 of the circumference in the circumferential direction. Complete circular columnar structure. The secondary side is optimized to realize mutual compensation at the working vibration frequency of the ultrasonic vibration system by using the leakage inductance of the secondary side coil and the equivalent capacitive reactance of the ultrasonic vibration system without additional compensation components. . The non-contact induction power supply device has a compact structure, a small moment of inertia, and can be expanded and installed, which can meet the working requirements of automatic tool change, high-speed rotation of the spindle, and high power of the ultrasonic vibration system in ultrasonic milling; install two sets of the non-contact The induction power supply device can also meet the power supply requirements of ellipse ultrasonic milling.
