Tool for the construction of vehicle body parts has a worm screw and worm screw wheel, in the transmission between the drive and the toggle lever linkage, with a self-lubricating action

摘要

The tool has a toggle lever linkage (26,27,34,36) between the drive (5) and the working tool section. (5) has an electromotor, with a worm screw (13) coupled to a motor drive shaft (9), meshing with a worm screw wheel (14) in the interior (10) of the tool head (1). A cam (21) is integral with (14), working with a swing axis (23), with its longitudinal axis parallel to the rotary axis (15) of (14). The tool, with a clamping or welding or embossing action, has a toggle lever linkage (26,27,34,36) between the drive (5) and the working tool section. The drive has an electromotor, with a worm screw (13) coupled to the motor drive shaft (9), meshing with a worm screw wheel (14) within the interior (10) of the tool head (1). A cam (21) is in one piece with the worm screw wheel, working with a swing axis (23), with its longitudinal axis parallel to the rotary axis (15) of the worm screw wheel. The toggle lever linkages are on the cam swing axis on diametrically opposite sides of the worm screw wheel.
