UTILIZING A FENCE ASSEMBLY THAT PROVIDES SURFACES AT DIFFERENT ANGLES
Techniques utilize a fence assembly which includes a fence member constructed and arranged to (i) install on a saw base and (ii) provide a first surface that restricts movement of an object in a first direction when the fence member is installed on the saw base. The fence assembly further includes a stop member constructed and arranged to provide a second surface that restricts movement of the object in a second direction that is different from the first direction when the stop member is in a fixed position relative to the fence member. The fence member further includes positioning hardware constructed and arranged to position the stop member in the fixed position relative to the fence member. Actuation of the positioning hardware enables the stop member to be adjusted to accommodate different object for cutting.
Machine Tool
A machine tool, in particular a chop saw and/or miter saw, includes (i) at least one pivot arm, (ii) at least one drive unit arranged on the pivot arm, (iii) at least two energy storage units, in particular battery packs, which can be electrically connected in series, for supplying energy to the drive unit, and (iv) at least two coupling units for fastening the energy storage units to the pivot arm. The coupling units are arranged on the pivot arm at an offset to one another with respect to a longitudinal axis of the pivot arm, the longitudinal axis of the pivot arm running at least substantially parallel to coupling surfaces, in particular main extension planes, of the coupling units.
Multi-function power saw system
A power saw system including a workstation having a table top surface, a saw arm coupled to the workstation at a first hinge member, the saw arm being configured to pivot toward and away from the table top surface about the first hinge member, a circular saw coupled to a distal end of the saw arm, and a second hinge member provided to the saw arm between the first hinge member and the circular saw, the second hinge member configured such that circular saw can be selectively rotated about the second hinge member in a direction lateral to an axis of the saw arm.
Miter saw
A bevel angle lock and detent system for a miter saw includes a first locking unit fixed relative to the turntable and a second locking unit coupled to a bevel arm of the miter saw. An actuator is moveable between a first position and a second position to move the second locking unit relative to the first locking unit. In the first position, a brake member of the second locking unit is engaged with an arcuate surface of the first locking unit to lock a saw unit relative to a turntable. In the second position, the brake member is disengaged from the arcuate surface, thereby permitting pivoting movement of the saw unit, and a detent member of the second locking unit is engageable a detent aperture of the first locking unit to locate the saw unit relative to the turntable at one predetermined bevel angle.
Utilizing a fence assembly that provides surfaces at different angles
Techniques utilize a fence assembly which includes a fence member constructed and arranged to (i) install on a saw base and (ii) provide a first surface that restricts movement of an object in a first direction when the fence member is installed on the saw base. The fence assembly further includes a stop member constructed and arranged to provide a second surface that restricts movement of the object in a second direction that is different from the first direction when the stop member is in a fixed position relative to the fence member. The fence member further includes positioning hardware constructed and arranged to position the stop member in the fixed position relative to the fence member. Actuation of the positioning hardware enables the stop member to be adjusted to accommodate different object for cutting.
ELECTRIC SAW
The invention relates to an electric saw comprising: a frame (2) mounted on a base (1), a cutting head (3) mounted on the frame by using a rotating shaft (4) in the vertical direction and an adjustable stop (5) limiting the descent of the head and the cutting depth. The adjustable stop (5) comprises: a rod (51) mounted in a through manner, with the possibility of longitudinal sliding, in a passage (53) defined in the cutting head (3) and facing a fixed stop (21) defined in the frame (2); and a screw (54) for lateral tightening and fixing of the rod (51) inside the passage (53). The screw (54) comprises an actuation knob (55) and is threadedly mounted in a hole defined in the cutting head (3) and leading into the mounting passage (53) of the rod (51).
Saw drivetrain with a chain drive and gear train
A saw device includes a motor having a motor output shaft and a drivetrain that includes a gear train and a chain drive. The gear train has a first gear fixedly connected to the motor output shaft and a second gear fixedly connected to an intermediate shaft, the first gear meshing with the second gear so as to transmit rotation from the motor output shaft to the second gear. The chain drive has a driving sprocket fixedly connected to the intermediate shaft, a driven sprocket, and a chain configured to transmit rotation of the driving sprocket to rotation of the driven sprocket. The saw device further includes an arbor shaft fixedly connected to the driven sprocket, the arbor shaft configured to mount a saw blade such that the saw blade rotates with the arbor shaft, and an upper guard configured to enclose at least a portion of the saw blade.
POWER TOOL BLADE TYPE DETECTION AND AUTOMATIC SPEED ADJUSTMENT
Systems and methods are provided for an electric tool (e.g., a power tool) that includes an output driver for receiving an accessory, and an accessory-type detector. A motor of the electric tool is coupled to the output driver for driving the accessory. The power tool also includes an operation trigger for activating the motor and a motor controller. The motor controller includes an electronic processor that is coupled to the accessory-type detector, the motor, the operation trigger, and a memory. The memory stores instructions that when executed by the electronic processor cause the motor controller to detect a characteristic of the accessory from output of the accessory-type detector. The motor controller determines an operational characteristic for the accessory based on the detected characteristic, and controls operation of the motor to drive the accessory according to the operational characteristic when the operation trigger is activated.
Table saw and miter saw combination apparatus
A table saw and miter saw combination apparatus for combining the functionalities of table saws and miter saws includes a table housing having a table blade slot extending through to a table inside. A table saw is coupled to the table housing within the table inside and has a table blade extending through the table blade slot. The table saw has a power switch coupled to the table front side. A miter housing is coupled to the table housing. The miter top side has a base cutout. A miter base is coupled to the miter housing being pivotably coupled within the base cutout. The miter base has a miter blade slot extending therethrough. A miter saw is coupled to the miter housing. The miter saw has a miter arm. The miter saw has a miter handle coupled the miter arm. The miter handle has a power trigger.
Miter saw
A benchtop cutting machine (1), such as a miter saw, includes: a base (2); a turntable (3), which is rotatable relative to the base; and a lock mechanism (40), which locks the rotation of the turntable relative to the base. The lock mechanism comprises a locking pin (45), which is movable along its axial direction and locks the rotation of the turntable by engaging with the base, and a manipulatable lever (41), which is pivotable in an up-down direction to release the engagement of the locking pin from the base. The manipulatable lever has a pivot point or center of rotation (42) that is located upward of the locking pin.
