Abstract

The micro-displacement transmission unit is placed in parts of machines and automatic lathes. A sealed hydraulic oil system allows the transmission of work of a reversible movement under the pressure of a piston (2) of a emitter jack (3) placed on a manual or mechanical control (6). The mechanical control feeds to a receptor jack (10) such that in pushing or pulling on the piston (2) of the emitter jack (3). The jack acts directly onto the piston (9) of the receptor jack (10) by the intermediary of piping (7) of the oil filled sealed hydraulic circuit.

Description

La présente invention concerne un dispositif hydraupneumatique pour la transmission d'un mouvement sensitif ou mécanique. The present invention relates to a hydraupneumatic device for the transmission of a sensitive or mechanical movement.

La transmission est traditionnellement effectuée par cable ou tringlerie ou biellettes et mécanique : pneumatique ou hydraulique pour un mouvement rectiligne. The transmission is traditionally carried out by cable or linkage or rods and mechanical: pneumatic or hydraulic for a rectilinear movement.

Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique un système hydraupneumatique placé dans les machines et automates. The device according to the invention overcomes this drawback. According to a first characteristic, it in fact comprises a hydraupneumatic system placed in machines and automata.

C'est un circuit étanche d'huile hydraulique. Il peut être une rallonge de transmission micrométrique. It is a sealed hydraulic oil circuit. It can be an extension of micrometric transmission.

Selon une forme de réalisation préférentielle en poussant sur le piston de la vis corps de vérin et de serrage émettrice on obtient le mouvement sur le piston de la vis corps de vérin et de serrage réceptrice. According to a preferred embodiment by pushing on the piston of the jack body screw and emitting clamping, movement is obtained on the piston of the jack body screw and receiving clamping.

Le mouvement sur le piston de la vis corps de vérin et de serrage émettrice peut être transmis par la main, une came, une articulation, une vis micrométrique, un vérin pneumatique ou hydraulique pendant la course ou en bout de course. Le circuit peut commander ou recevoir un ordre à l'extrémité d'un déplacement. The movement on the piston of the emitting cylinder and tightening screw can be transmitted by hand, a cam, an articulation, a micrometric screw, a pneumatic or hydraulic cylinder during the race or at the end of the race. The circuit can command or receive an order at the end of a movement.

Le circuit peut être composé de plusieurs vérins émetteurs et un vérin récepteur ou inversement. The circuit can be composed of several transmitting cylinders and a receiving cylinder or vice versa.

Les joints entre le vérin émetteur et le vérin récepteur peuvent être des joints standards ou des joints de plomberie pour un travail lent ou rapide de faible puissance ou de puissance. Le circuit est une liaison intermédiaire. The joints between the sending cylinder and the receiving cylinder can be standard joints or plumbing joints for slow or fast work of low power or power. The circuit is an intermediate link.

Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.

Les figures 1 à 4 représentent en coupe des variantes de ce dispositif. Figures 1 to 4 show in section variants of this device.

En référence à ces dessins, les dispositifs représentés sur les figures comportent une vis corps de vérin et de serrage émettrice (3) composée de la pièce support (1) du piston (2) du joint torique (4) de la fixation (5) du poussoir ou de l'articulation (6) du tuyau hydraulique (7) qui est souple au montage ou rigide dans l'exemple d'une pièce massive renvoi d'angle et palonnier : Fig 3, Fig 4.  With reference to these drawings, the devices represented in the figures comprise a jack body and emitting clamping screw (3) composed of the support part (1) of the piston (2) of the O-ring (4) of the fixing (5). of the plunger or the articulation (6) of the hydraulic hose (7) which is flexible for mounting or rigid in the example of a massive piece of angle gear and spreader: Fig 3, Fig 4.

La vis corps de vérin et de serrage réceptrice (10) est reliée au tuyau collet rabattu, son support (8) est réversible avec le support (1) ou identique, le piston (9) reçoit la transmission hydraulique, il peut être lié à un poussoir ou une articulation. Il possède un joint torique d'étanchéité (4) et la fixation est représentée par l'écrou (11)
Les fixations des vérins sont un choix à la réalisation de l'utilisateur, il y a plusieurs exemples.The jack body and receiving clamping screw (10) is connected to the folded collar pipe, its support (8) is reversible with the support (1) or identical, the piston (9) receives the hydraulic transmission, it can be linked to a pusher or a joint. It has an O-ring seal (4) and the fixing is represented by the nut (11)
Cylinder fixings are a choice for the user, there are several examples.

En référence, à ces dessins, le dispositif fonctionne comme ce qui suit
- La paroi supérieure du vérin émetteur est constituée d'une chambre à l'air libre.With reference to these drawings, the device operates as follows:
- The upper wall of the emitting cylinder consists of an open air chamber.

- La paroi inférieure du vérin émetteur est constituée d'une chambre étanche. - The bottom wall of the emitting cylinder consists of a sealed chamber.

- La paroi supérieure du vérin récepteur est constituée d'une chambre sans étanchéité avec l'atmosphère. - The upper wall of the receiving cylinder consists of a chamber without sealing against the atmosphere.

- La paroi inférieure du vérin récepteur est constituée d'une chambre étanche avec le circuit d'huile hydraupneumatique, sous les deux pistons. - The lower wall of the receiving cylinder consists of a sealed chamber with the hydraupneumatic oil circuit, under the two pistons.

Les pistons pouvant avoir un diamètre de 2 à 6 millimètres suivant l'utilisation pour l'usage courant.  The pistons can have a diameter of 2 to 6 millimeters depending on the use for current use.
