Abstract:
The present invention provides a clamp (1) for holding a workpiece (12) that is particularly suitable for use in CNC machining. The clamp (1) is particularly useful for use in picture-frame machining techniques as it allows a workpiece (12) to be held in a position wherein a machine can have substantially unencumbered access to both sides of the workpiece (12) without the need to remove the workpiece (12) from the clamp (1). The clamp (1) comprises a frame comprising a base (2), a first arm (3), and a second arm (4), the first arm (3) and the second arm (4) each mounted to the base (2) at an inner end such that they are parallel with one another. The clamp (1) further comprises a set of opposed vices (5, 6, 7, 8) mounted at facing sides of the frame to hold a workpiece (12) therebetween, the set of vices (5, 6, 7, 8) consisting of exactly three self-centering vices (5, 6), two mounted at the first side of the frame and one mounted at a second opposing side of the frame, and optionally one or more floating vices (7, 8). In embodiments of the invention the first arm (3) and the second arm (4) are mounted to the base (2) at an inner end by a vice mechanism such that they are parallel with one another and are movable towards and apart from one another. The present invention also provides a method of using the clamp (1) for machining.
Abstract:
La présente invention vise à permettre de caler une plinthe (8) contre un mur (11) sans abimer le mur, le revêtement de sol (7) ou la plinthe. A cette fin, l'invention a pour objet un dispositif de maintien comprenant : • Un socle (100) comprenant : o une face d'appui (112), définissant un plan d'appui (P), et destinée à être, en position d'utilisation, en appui contre un revêtement de sol (7); o une face de contact (113), destinée, en position d'utilisation, à être en contact avec une presse (9); o la face de contact et la face d'appui étant solidaires rigidement l'une de l'autre, et formant un angle (a) entre elles • Une griffe (105) fixée au socle par l'intermédiaire d'un bras de fixation (105b-102) de manière à ce que, en position d'utilisation, la griffe soit sécante avec le plan d'appui et soit insérée dans l'espace de dilatation (10), entre le mur et le revêtement de sol.
Abstract:
A one-piece barrel assembly cart includes a right assembly cart base connected with a left assembly cart base and at least three stabilizer rings that are attached to the assembly cart base. The one-piece barrel assembly cart may be used to stabilize a tapered cured composite barrel, for example the large fuselage barrel of the aft section of a large new generation aircraft, such as a 7E7 Boeing airplane. A modular assembly cart includes at least two identical modules. Each of these modules includes a cart base and a stabilizer ring. The diameter of the inner surface of the stabilizer ring may vary as needed. Other modules including a fuselage support may be added. By providing modular assembly carts any shape and size of a one-piece composite barrel may be stabilized after curing of the composite material.
