Description

       

  Dispositif de protection des glissières pour machines-outils.

  
Dans la. plupart des machines-outils, il existe un banc horizontal présentant des glissières sur lesquelles se déplacent divers organes appelés chariots, tables, trainards, etc., suivant les machines. Ces glissières peuvent présenter divers profils; dans certaines machines, par exemple les machines à rectifier, elles sont avantageusement à profil en V.

  
Ces glissières doivent être soigneusement graissées pour que le mouvement s'exécute sans résistance, et elles doivent être tenues très propres. Cette dernière condition est difficile à réaliser; la chute continue des poussières encrasse peu à peu les glissières; d'autre part, les outils de la machine laissent tomber des copeaux ou projettent des parcelles de métal de tous cotés. Ces débris de métal, en s'engageant

  
mobiles

  
entre les glissières et les organes/, tendent à déplacer ceuxci et à diminuer la précision du travail. De plus, ces copeaux ou débris peuvent rayer les glissières et peu à peu les user

  
et les déformer.

  
On a déjà proposé de couvrir les glissières, mais les dispositifs proposés sont compliqués et d'un fonctionnement'peu suri et n'ont pas donné entièrement satisfaction.

  
La présente invention a pour objet un dispositif de protection des glissières qui est très simple, ne cause aucun encombrement sur la sa chine, et qui fonctionne avec certitude.

  
Ce dispositif consiste en principe en une bande plate, par exemple en métal mince, qui est disposée de manière à constituer une courroie sans fin, dont la partie supérieure, solidaire de l'organe mobile sur les glissières, recouvre 'ces glissières tout en accompagnant l'organe mobile dans ses déplacements.

  
Pour fixer les idées on a représenté dans le dessin annexé une forme d'exécution du nouveau dispositif. Dans ce dessin :

  
la fige 1 est une vue en élévation de l'ensemble d'une rectifieuse à laquelle l'invention est appliquée;

  
la fig. 2 est une vue de détail montrant 4 plus grande échelle l'une des extrémités du dispositif;

  
la fig. 3 est une coupe par III-III de la fig. 2.

  
Comme on le voit sur ce dessin, sur le banc B de la machine peut se déplacer un support M dit montant, sur lequel glisse un chariot C portant les outils de rectification.

  
 <EMI ID=1.1> 

  
à profil en V, qui s'étendent d'un bout à l'autre du banc.

  
Ces glissières sont recouvertes par une bande b en métal mince, ou en toute autre matière flexible et résistante, dont les bords s'appliquent sur les bords [pound] de la glissière, ainsi qu'on le voit fige 3 . Les extrémités de cette bande

  
 <EMI ID=2.1> 

  
leaux de renvoi! et [pound] et s'étend sous la glissière d'un bout à l'autre du banc, comme le montre la fig. 1.

  
Le rouleau d est monté fixe et le rouleau! est monté réglable. Ce dernier est porté par un axe h, monté dans

  
 <EMI ID=3.1> 

  
Des bandes de cuir ou de feutre k recouvrent les bords de la lame b, de façon à former joint et à empêcher toute pénétration de poussière ou de parcelles de métal.

  
Grâce à la disposition qui vient d'être décrite, les glissières sont recouvertes sur toutes leur étendue et parfaio tement protégées. Le dispositif ne cause pas d'encombrement

  
 <EMI ID=4.1> 

  
lie par rapport au banc. Il est facile à monter, démonter et régler.

  
Tous les détails d'exécution pourront varier dans tous les cas sans changer le principe de l'invention.

REVENDICATIONS

  Guardrail protection device for machine tools.

  
In the. Most machine tools, there is a horizontal bench with slides on which move various organs called carriages, tables, saddles, etc., depending on the machines. These slides can have various profiles; in some machines, for example grinding machines, they are advantageously V-shaped.

  
These slides must be carefully greased for the movement to run without resistance, and they must be kept very clean. This last condition is difficult to achieve; the continuous fall of dust gradually clogs the slides; on the other hand, the tools of the machine drop chips or throw pieces of metal on all sides. These metal debris, by engaging

  
mobile

  
between the slides and the members / tend to move them and reduce the precision of the work. In addition, these chips or debris can scratch the slides and gradually wear them out.

  
and distort them.

  
It has already been proposed to cover the slides, but the proposed devices are complicated and not very reliable in operation and have not been entirely satisfactory.

  
The object of the present invention is a device for protecting the slideways which is very simple, does not cause any obstruction on the machine, and which operates with certainty.

  
This device consists in principle of a flat strip, for example of thin metal, which is arranged so as to constitute an endless belt, the upper part of which, integral with the movable member on the slides, covers these slides while accompanying the mobile organ in its movements.

  
To clarify ideas, the accompanying drawing shows an embodiment of the new device. In this drawing:

  
fig 1 is an elevational view of the assembly of a grinding machine to which the invention is applied;

  
fig. 2 is a detail view showing one of the ends of the device on a larger scale;

  
fig. 3 is a section through III-III of FIG. 2.

  
As can be seen in this drawing, on the bench B of the machine can move a so-called upright support M, on which slides a carriage C carrying the grinding tools.

  
 <EMI ID = 1.1>

  
V-shaped profile, which extend from one end of the bench to the other.

  
These slides are covered by a strip b of thin metal, or any other flexible and resistant material, the edges of which are applied to the edges [pound] of the slide, as seen in fig 3. The ends of this strip

  
 <EMI ID = 2.1>

  
return waters! and [pound] and extends under the slide from one end of the bench to the other, as shown in fig. 1.

  
The roller d is mounted fixed and the roller! is mounted adjustable. The latter is carried by an h axis, mounted in

  
 <EMI ID = 3.1>

  
Strips of leather or felt k cover the edges of the blade b, so as to form a seal and to prevent any ingress of dust or particles of metal.

  
By virtue of the arrangement which has just been described, the slides are covered over their entire extent and perfectly protected. The device does not cause congestion

  
 <EMI ID = 4.1>

  
binds to the bench. It is easy to assemble, disassemble and adjust.

  
All the details of execution may vary in all cases without changing the principle of the invention.
