An excavation cutting toolholder retention system (100). The cutting toolholder retention system (100) includes a cutting toolholder (108) having a flange recess and a holder engagement surface (140) and a support block (102) having a toolholder bore (104) into which the cutting toolholder is inserted and a block pin bore (106) intersecting the toolholder bore, the block pin bore (106) defining a block engagement surface (164) which is inclined downwardly relative to the toolholder bore. The cutting toolholder retention system (100) further includes a pin (112) having a pin shaft (180), the pin shaft having a pin flange (190) which engages the flange recess so as to limit translational movement of the pin shaft. The pin engages the block engagement surface (164) and the holder engagement surface (140) such that the pin (112) may be moved to draw the cutting toolholder (108) into the toolholder bore (104)

L'invention a trait à un dispositif de maintien de porte-outil de coupe d'excavation (100). Ce dispositif (100), qui comporte un porte-outil de coupe (108) pourvu d'un évidement pour collerette et d'une surface de contact de support (140), comporte également un bloc de soutien (102) pourvu d'un alésage (104), dans lequel vient s'insérer le porte-outil de coupe, et d'un alésage pour broche (106) recoupant le premier alésage. Cet alésage pour broche (106) définit une surface de contact de bloc (164) inclinée vers le bas par rapport à l'alésage du porte-outil. Le dispositif de maintien de porte-outil de coupe (100) comporte, de surcroît, une broche (112) ayant une tige de broche (180) elle-même pourvue d'une collerette (190) venant au contact de l'évidement susmentionné de manière à limiter tout mouvement de translation de la tige. La broche vient au contact de la surface de contact de bloc (164) et de la surface de contact de support (140) de sorte qu'il est possible de la déplacer pour amener le porte-outil de coupe (108) dans l'alésage (104) qui lui est destiné.
