Abstract

The suspended grindstone (32) is held with its motor (10) by a casing (24)that swings (27), pivots (26) and rises (28) with all of its adjustment andlocking screws (33, 34, and 35) for choosing the sharpening angle and theheight of the depth limiting pin. The assembly is operated simultaneously byvirtue of a single lever (11). The advance of each tooth of the chain towardsthe grindstone is achieved by a lever (12) operating two parts: the first(15) equipped with an adjustable stop and a moveable latch (13) at the end ofthe course for blocking the chain against the chain guide of the saw. Thislever also has a retracting spring (29). Two lateral screws (5) pivot on anaxis (31) and are retractable when working with the machine, for adjustmentand adaptation to the wear on the grindstone (32) by raising it or removingit from the machine on the chain guide. Lastly, two blocking wing nuts (30)are used to fix the sharpener on the chain guide.

Description

Affûteuse de chaîne de tronçonneuse - DescriptionChainsaw Chain Sharpener - Description

Les chaînes de tronçonneuses s'affûtent encore à la lime. Certains bûcherons le font très bien mais cela demande du temps. La majorité d'entre eux n'y parvient toutefois pas parfaitement, de ce fait leur chaîne ne coupe plus et la denture devient irrégulière. Il existe des meuleuses d'atelier mais l'inconvénient est gu'il faut enlever la chaîne de la tronçonneuse pour l'affûter, ce gui prend beaucoup de temps.Chainsaw chains are still sharpened with a file. Some loggers do it very well, but it takes time. The majority of them however do not succeed perfectly, therefore their chain no longer cuts and the teeth become irregular. There are workshop grinders but the disadvantage is that you have to remove the chain from the chainsaw to sharpen it, this mistletoe takes a long time.

L'affûteuse DELAGAüME a été conçue pour travailler en forêt. Elle se blogue sur le guide-chaîne de la tronçonneuse et s'arrime à tout support en bois. Elle est actionnée par un moteur continu de 12 volts ou par un moteur à accumulateur. Le résultat de l'affûtage est comparable à celui réalisé en atelier sans avoir eu besoin d'ôter la chaîne.The DELAGAüME sharpener was designed to work in the forest. It is blogged on the chain saw's guide bar and stowed on any wooden support. It is powered by a 12-volt continuous motor or by an accumulator motor. The result of the sharpening is comparable to that achieved in the workshop without having to remove the chain.

Les avantages obtenus grâce à cette invention consistent en un gain de temps important pour un résultat d'affûtage optimal.The advantages obtained thanks to this invention consist in a significant time saving for an optimal sharpening result.

L'invention est exposée ci-après plus en détail à l'aide de trois dessins gui représentent, à échelle réduite, une vue de face, de profil et de dessus de l'outil à l'état assemblé.The invention is set out below in more detail using three drawings which represent, on a reduced scale, a front view, in profile and from above of the tool in the assembled state.

Claims (1)

- Revendication L'affûteuse DELAGAUME est une petite meule fine (32) pour chaîne de tronçonneuse. Elle est actionnée par un moteur 12 volts (10) raccordé à la batterie du véhicule forestier. Cette meuleuse suspendue par son axe (26) oscille entre chaque dent de la chaîne et aiguise toutes ces dents alternativement en une seule passe selon l'angle désiré. L'appareillage se monte sur le guide de la tronçonneuse sans avoir besoin de démonter la chaîne et le tout se fixe sur un support en bois. Le levier de gauche (12) réalise deux fonctions : faire avancer les dents une à une devant la meule et les maintenir pendant l'affûtage avec le cliquet (13). Le levier de droite (11) positionne la meule à l'angle de coupe désiré puis la bascule à droite ou à gauche. Ces mouvements s'effectuent grâce à deux axes (26 et 27). Ce même levier permet encore de repasser l'ergot limitateur de profondeur en dévissant la vis adéquate (33) et en soulevant l'ensemble sur son axe (28) grâce à une vis de réglage (35). Le réglage et le rattrapage d'usure de la meule se fait par l'intermédiaire de 2 vis latérales (5). Remarque : Le moteur (10) tournant dans les deux sens, il est aussi possible d'affûter toutes les dents de droite dans une première passe et ensuite toutes celles de gauche dans un second passage.- Claim The DELAGAUME sharpener is a small fine grinding wheel (32) for chainsaw chains. It is powered by a 12 volt motor (10) connected to the forest vehicle battery. This grinder suspended by its axis (26) oscillates between each tooth of the chain and sharpens all these teeth alternately in a single pass at the desired angle. The equipment is mounted on the chainsaw guide without the need to dismantle the chain and everything is fixed on a wooden support. The left lever (12) performs two functions: advancing the teeth one by one in front of the grinding wheel and maintaining them during sharpening with the ratchet (13). The right lever (11) positions the wheel at the desired cutting angle and then switches it to the right or left. These movements are carried out by two axes (26 and 27). This same lever also makes it possible to iron the depth limiting lug by unscrewing the appropriate screw (33) and lifting the assembly on its axis (28) using an adjustment screw (35). The grinding wheel wear adjustment and adjustment is done by means of 2 lateral screws (5). Note: With the motor (10) rotating in both directions, it is also possible to sharpen all the right teeth in a first pass and then all those on the left in a second pass.
