An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces of a workpiece, comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame, rotatable relative to the frame about a first pivot axis, and translationally fixed relative to the frame. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is coupled to the frame and is configured to operate in tension. The second biasing member is positioned, in compression, between the frame and the rotation-control member.

The present disclosure relates generally to a bi-directional clamp system and method of use. More particularly, a bi-directional clamp with two clamp bars and two clamping assemblies are described herein. The clamp assemblies have a plurality of arms freely movable in response to a material load is described herein.

A clamping system useful in miter edge fabrication. Two separate units, each including a vacuum plate may be placed on'separate slabs. The units are connected with a knuckle that can be rotated to provide connection of the slabs in a variety of angles. The units are vacuum sealed to the slabs via pressure tubes. The vacuum plates may include various sections of varied sizes to connect to different sized slabs. When the knuckle is locked, a worm gear will provide for lateral movement, relative the knuckle, to provide precision fitting of slabs.

A gripping device for a panel of a section of a fuselage of an aircraft, the panel including a skin and having an arcuate shape about a longitudinal axis X. The gripping device includes two gripping subsystems arranged at a distance from one another parallel to the longitudinal axis X, and each gripping subsystem includes a central element fastened to the panel, and two lateral elements fastened on either side of the central element by fasteners, and each lateral element includes pressurizers which come against the skin to apply a tension thereto in the opening direction of the arcuate shape. Such a gripping device makes it possible to ensure the shape of the panel when it is transported and until it is fastened to other panels in order to produce the section of the fuselage.

A splicing structure, a splicing table, and a splicing and fitting device are provided. The splicing structure includes: a splicing adjustment component, a splicing alignment component, and a splicing base. The splicing adjustment component and the splicing alignment component are connected to the splicing base; and the splicing adjustment component is configured to support at least two to-be-spliced pieces; the splicing alignment component is configured to align the at least two to-be-spliced pieces to a first reference site. The splicing adjustment component is further configured to drive at least one of two adjacent to-be-spliced pieces in the at least two to-be-spliced pieces to move relative to the first reference site, to enable the two adjacent to-be-spliced pieces to be close to or far away from each other.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

An apparatus (100) for applying pressure to at least a portion of an edge surface (192), which bridges opposing faces (194) of a workpiece (190), comprises a frame (110), a first roller (120), a second roller (130), a rotation-control member (140), a first biasing member (150), and a second biasing member (160). The first roller (120) and the second roller (130) are coupled to the frame (110), are rotatable relative to the frame (110), and are translationally fixed relative to the frame (110). The rotation-control member (140) is movable relative to the frame (110), controlling rotation of the first roller (120) and the second roller (130) relative to the frame (110). The first biasing member (150) is configured to operate in compression along a second axis (102). The second biasing member (160) is positioned, in compression, between the frame (110) and the rotation-control member (140).

The present invention relates to a display manufacturing field. Disclosed is a substrate clamping device. The substrate is arranged on the trolley. The clamping arms arranged on the trolley are used for fixing the substrate. The clamping arms move up and down as rotating by means of the rotary lifting mechanism, thereby clamping and releasing the substrate. The impact on the substrate is small in the entire clamping process, and the handling of the substrate is facilitated. The clamping arms arranged around the substrate and symmetrically arranged in pair can keep the force of the substrate uniformly and can clamp the substrate more reliably.

A clamping device is used for joining panels or boards with highly cosmetic appearance at the visible joined surface. The clamping device can include mechanisms to support and move one panel relative to another panel in two directions perpendicular to the beveled edges of the panels. The clamping device can include a rotational mechanism to rotate one panel around a direction parallel to the beveled edge.
