A clamping system for a component, especially for an article of footwear or a sports article, may include: (a) a first member; (b) a second member, (c) a pivot about which the first member and the second member are rotatable relative to each other; (d) a first bracket slidably movable along a first path on the first member and a second path, by a first distance, on the second member, when the first member and the second member are rotated relative to each other from a first angle to a second angle; and (e) at least a second bracket slidably movable along a third path on the first member and a fourth path, by a second distance, on the second member, when the first member and the second member are rotated relative to each other from the first angle to the second angle.

A chuck for gripping and moving cylindrical bodies, in particular fittings and pipe segments, including a main body defining an axis of rotation and a plurality of jaws fastened to the main body; the jaws are movable between a position of maximum closure, in which they are at the minimum distance from the axis of rotation, to a position of maximum opening, in which they are at the maximum distance from the axis of rotation; the chuck has an adjuster means for adjusting the positions of maximum closure and maximum opening and a movement means for moving the jaws between the positions of maximum closure and maximum opening; the chuck includes a fixing means adapted to allow the axial fixing of the chuck to a support member and the connection of the chuck to the support member so that they are angularly rotatable with respect to each other.

A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.

A hybrid holding device used in a milling machine, comprising a base with mounting structures for detachably fastening the hybrid holding device securely onto a workbench of the milling machine in a fixed stationary position. The hybrid holding device further includes moveable multi-jaw assembly that includes at least three jaws that directly receive and securely hold a workpiece without an adapter.

A wheel rim chuck has a chuck seat (10) and multiple soft jaws (20). The soft jaws are arranged radially at equiangular intervals and slidably mounted on the chuck seat (10). Each soft jaw (20) has a claw (21) having a protrusion (211), a clamping groove (213), and an inclined plane (216). The protrusion (211) protrudes from a side of the soft jaw (20) away from the chuck seat (10). The clamping groove (213) is recessed in a side of the protrusion (211) facing the center (111) of the chuck seat (10) and having a side wall (214) and a bottom wall (215). The inclined plane (216) extends longitudinally and obliquely from the bottom wall (215) away from the side wall (214) of the clamping groove (213).

Disclosed is the shape of a curvature of two or more pathways for a device having moving parts that cause movement of an object along those pathways, such that the device can locate or hold the object. In the embodiment, an apparatus is described that centers and optionally locks an object at a desired location. The applications for such a device are varied and can range from chucking a workpiece of varying diameters in a lathe, to centering a drone on a landing zone, to medical and scientific devices to capture and center objects to study, to moving atomic level objects using an electromagnetic field. The scope of this disclosure is the mathematics that defines the mirrored curvatures of each curved pathway and the positioning of the curvatures relative to each other, and the relative movement of the mirrored curvatures to cause the desired effect.

A portable pipe threader includes a collapsible stand, a housing supported by the collapsible stand, the housing supporting a battery-powered drive assembly, a first set of guide rails extending from a first end of the housing and supporting pipe threading tools, and a second set of guide rails extending from a second end of the housing and supporting a roll groover. The roll groover is configured to swing about a first one of the second set of guide rails to selectively engage a second one of the second set of guide rails.

A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.

A workpiece clamping system for a measuring machine includes a rotary table disposed in a workpiece rotation axis and includes a chuck for the concentric accommodation of a workpiece, a rotary drive for the rotary table, an upper centering tip mountable or mounted on the measuring machine in the workpiece rotation axis vertically opposed to the rotary table, and a lower centering tip mountable or mounted on the rotary table in addition to the chuck for accommodating a workpiece between the centering tips instead of in the chuck, wherein the lower centering tip is provided and formed to be concentrically clamped in the chuck instead of a workpiece, and in that the workpiece clamping system is provided with a conveying device for vertically or vertically and horizontally conveying the lower centering tip into and from its clamping position in the chuck.

A hybrid holding device used in a milling machine, comprising a base with mounting structures for detachably fastening the hybrid holding device securely onto a workbench of the milling machine in a fixed stationary position. The hybrid holding device further includes moveable multi-jaw assembly that includes at least three jaws that directly receive and securely hold a workpiece without an adapter.
