Abstract:
Die Erfindung geht aus von einer Werkzeugmaschine, insbesondere von einer Kapp- und/oder Gehrungssäge, mit zumindest einem Schwenkarm (12),mit zumindest einer an dem Schwenkarm (12) angeordneten Antriebseinheit (14), mit zumindest zwei elektrisch reihenschaltbaren Energiespeichereinheiten (16, 18), insbesondere Akkupacks, zu einer Energieversorgung der Antriebseinheit (14) und mit zumindest zwei Kopplungseinheiten (20, 22) zu einer Befestigung der Energiespeichereinheiten (16, 18) an dem Schwenkarm (12). Es wird vorgeschlagen, dass die Kopplungseinheiten (20, 22) entlang einer Längsachse (24) des Schwenkarms (12) betrachtet versetzt zueinander an dem Schwenkarm (12) angeordnet sind, wobei die Längsachse (24) des Schwenkarms (12) zumindest im Wesentlichen parallel zu Kopplungsflächen (26, 28), insbesondere Haupterstreckungsebenen, der Kopplungseinheiten (20, 22) verläuft.
Abstract:
A sawmill (8) includes a four-stroke internal combustion engine (30) having an output shaft (36) for driving a sawblade (29) and the output shaft has a longitudinal axis. The engine (30) is mounted on the sawmill (8) for rotation between a first operative position with the longitudinal axis of the output shaft (36) extending at a first angle, and a second operative position with the longitudinal axis of the output shaft (36) extending at a second angle transversely to the first angle. The engine (30) has fuel injection (194) to facilitate operation in the first and second operative positions and a lubrication system incorporating a wet sump (37a, 37b). An oil pick up (40) for the lubrication system is disposed to pick up oil from the wet sump (37a, 37b) at both the first and second operative positions.
Abstract:
A power tool assembly includes a workpiece support surface, a latch movable between a first latch position whereat a drop arm assembly cannot be moved from a first position whereat a shaping device does not extend above the workpiece support surface to a second position whereat the shaping device extends above the workpiece support surface, to a second latch position whereat the drop arm assembly can be moved from the first position to the second position, an actuator housing configured to receive an actuator device, and a reaction plug configured to be selectively seated with the actuator housing, the reaction plug configured such that when an actuator device is installed in the actuator housing and the reaction plug is moved from an unseated position to a fully seated position, the reaction plug forces the actuator device to move the latch from the first latch position to the second latch position.
Abstract:
A method for operating an object detection system in a saw produces profiles for materials used in work pieces. The method includes operating a motor in the saw to move an implement and cut a work piece formed from a predetermined material, recording, a sensing signal produced in the object detection system during contact between the work piece and the implement, generating a detection profile for the material of the work piece based on the recorded sensing signal, storing, the detection profile in a memory in the saw, and operating the saw and the object detection system using the detection profile to distinguish between contact of the implement with a work piece formed from the predetermined material and contact of the implement with a portion of a body of an operator.
Abstract:
Embodiments of the present invention provide storage options for push-sticks used in connection with rip fences on table saws and similar cutting devices where push-sticks might be used. The push-stick storage system may include a rip fence and a push-stick retention mechanism. The push-stick retention mechanism may be defined by upright side walls that define a channel or slot therebetween for receiving a push-stick. The retention mechanism may also include a stop (or a stop block) positioned at a first position within the channel, and a retainer positioned at a second position within the channel.
Abstract:
A sliding table assembly for a main table of a saw machine includes a sliding table member having a planar upper surface, a miter slot, and a rail structure, and a bracket structure configured to be attached to a mounting structure on the main table of the table saw. The bracket structure is configured to squeeze the rail structure to provide zero clearance support for slidably retaining the sliding table member. Vertical and horizontal position adjustment mechanisms are operably connected to the bracket structure and configured to move at least a portion of the bracket structure horizontally as well as vertically with respect to the mounting structure to align the upper surface of the sliding table member in plane with the upper surface of the main table and to align the miter slot parallel to a blade of the saw machine.
