The present invention relates to a triple vice machining fixture configured to hold up to three workpieces simultaneously. The fixture includes a circular device and features three sets of dual jaws facing-off to each other and positioned at 120 degrees relative to each other. Each jaw set includes a stationary jaw and a receptacle jaw wherein the receptacle jaw has tapered wedges that secure the workpiece in place between the stationary jaw and the receptacle jaw. The fixture has three locators proximal to the center of the vice, wherein each locator is a travel stop to the back side of the jaws and are positioned in the same circular pattern as the jaws. The vice enables machinists, hobbyists and others to maintain versatility and work on multiple items or projects simultaneously.

The invention relates to vise pivotal jaws for holding irregular shaped objects and that are modular to work on various sized prior art vises. Also relates to pivotal jaws having aid to return back to a neutral center position. The design allows ease of disassembly for cleaning and reassembly.

A blade clamping device for a microtome is provided. The blade clamping device includes: a base part; a pressure plate rotatably connected to the base part via a rotation shaft; a clamping pin received in the base part, and configured to extend out of the base part and push the pressure plate to rotate, so as to clamp a blade between the base part and the pressure plate; and a drive unit received in the base part, connected to the clamping pin and configured to drive the clamping pin to extend out of the base part.

A device for holding in position a product to be processed includes a base connectable by magnetic interaction to a work surface of an apparatus for tumbling or polishing and comprising a first portion and a second portion movable along an operating direction mutually towards or away from a first and a second operating position. The device also includes a retaining support connected to the base and configured to hold in a stable position a product to be processed between a first and a second retaining element. Between the first and the second portion of the base an actuation member is interposed, configured to move the same portions between the first operating position and the second operating position. A method for holding in position a product to be processed is also disclosed.

A wind turbine blade apparatus comprising a root device including: a base having an upper surface with a radius of curvature and configured to receive a root portion of a blade, with housings disposed on lateral sides of the base. The housings including a groove configured to receive a bearing and a shaft extending at least partially through the base and housing. A tip device is also provided which includes a base, a rotatable support frame having: a first support configured to receive a pressure side of a wind turbine blade, a second support configured to receive a suction side of a wind turbine blade, and an opening, the opening configured to receive a portion of a wind turbine blade.

A wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.

A wind turbine blade rotating and braking apparatus comprising: a root device including: a root support member having an upper surface with a radius of curvature and configured to receive a portion (e.g. root) of a wind turbine blade, rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; braking mount on the sides of the root support member; and a braking mechanism (e.g. strap or band) fixedly attached to the first mount, releasably attached to the second mount and extending above the blade to apply a braking force to the blade. Once applied, the braking force can be maintained by a locking pin.

A fixture assembly may include a housing, a clamp assembly, and a drive mechanism. The clamp assembly may be movably mounted to the housing and may include a first clamp member and a second clamp member. The first and second clamp members may be linearly movable relative to the housing toward and away from each other. The drive mechanism may be coupled to the clamp assembly and the housing and may drive the clamp assembly relative to the housing such that the first clamp member moves linearly toward the second clamp member at a first speed in a first direction and the second clamp member moves linearly toward the first clamp member at a second speed in a second direction that is opposite the first direction. The first speed may be different than the second speed.
