Linear actuating device

A linear actuating device comprising:

• a rodless power cylinder unit including a cylinder barrel;
• a longitudinal base rigidly coupled to the cylinder barrel, said base having a width in the direction perpendicular to the axis of said cylinder barrel of the rodless power cylinder;
• a guide rail mounted on the top face of the base and extending in parallel with the axis of the cylinder barrel;
• a carriage disposed on the cylinder barrel and movable along the axis of the cylinder barrel;
• a slide table having an upper face and lower face disposed in parallel with said base, said slide table being coupled with and driven by said carriage and movable along said guide rail;
• wherein said carriage and said slide table are disposed on the side of cylinder barrel facing said guide rail;
• a stopper means for defining the end of the stroke of the slide table, said stopper means being provided with:
• a stopper member holder having a groove engaging the guide rail so as to facilitate adjustment of the position of said stopper member along the guide rail;
• a fastening means for fastening the stopper member holder to the base;
• and
• a stopper member mounted on the stopper member holder at a position offset from the guide rail in the direction to the cylinder barrel, said stopper member defining the end of the stroke of the slide table by engaging the slide table at the end of the stroke;
• and
• wherein said fastening means comprises a T-shape cross section groove disposed on the top face of the base and extending in parallel with the guide rail, a nut member accommodated in the T-shape cross section groove, a fastening bolt being screwed into the nut member in the T-shape cross section groove to thereby clamp the stopper member holder to the base, and wherein said nut member has a portion extending in the direction of movement of the slide table from the portion at which the nut member engages with the fastening bolt.
