摘要： A power tool includes a housing, a rotary motor disposed in the housing, a jack shaft coupled to the motor and a spindle mounted in the housing for carrying a tool. A first wobble plate assembly is coupled to the jack shaft for driving the spindle to reciprocate at least approximately linearly in a linear path along a predetermined axis. A counterweight is mounted in the housing for performing a rotative reciprocating motion and pivoting relative to the housing about a pivot axis. The pivot axis is disposed in a plane perpendicular to the predetermined axis and fixed relative to the housing. A second wobble plate assembly is coupled to the jack shaft for driving the counterweight. The use of the counterweight results in no friction or restriction with a large stroke and large area, so that stability is improved, fitting of the counterweight is simple and cost is reduced.

摘要： It is an object of the present invention to provide a useful technique for achieving weight reduction of the counter weight while reducing vibration in the reciprocating power tool. According to the invention, representative reciprocating power tool may include a motor, a tool bit, a slider, a motion converting mechanism, a counter weight and a component part of the motion converting mechanism. The tool bit performs a predetermined operation by reciprocating. The slider reciprocates to drive the tool bit. The motion converting mechanism converts a rotating output of the motor into a reciprocating movement of the slider. The counter weight reciprocates in a direction opposite to the reciprocating direction of the slider to reduce vibration caused by the reciprocating movement of the slider. The component part includes component of motion in a direction parallel to the reciprocating movement of the slider. The component part performs vibration reducing function together with the counter weight. Because component part can move parallel to the reciprocating slider to cooperate with the counter weight in reducing vibration caused within the power tool, the weight of the counter weight can be decreased while keeping the sufficient capability of vibration reducing function.
摘要翻译：本发明的目的是提供一种用于在减小往复动力工具中的振动的同时实现配重的减重的有用技术。根据本发明，代表性的往复动力工具可以包括马达，工具钻头，滑块，运动转换机构，配重和运动转换机构的组成部分。工具位通过往复运动执行预定的操作。滑块往复运动以驱动刀头。运动转换机构将电动机的旋转输出转换成滑块的往复运动。平衡重在与滑动件的往复运动方向相反的方向上往复运动，以减少由滑动件的往复运动引起的振动。部件包括在平行于滑块的往复运动的方向上运动的部件。组件与重量一起执行减振功能。由于在减少电动工具中产生的振动的同时，由于部件能够平行于往复运动的滑块移动，与配重配合，因此可以减轻配重的重量，同时保持充分的减振功能。

摘要： A hand-held power cutting tool has a generally cylindrical casing, which can be grasped in the palm of one hand, and whose rear portion housed an electric driving motor disposed in the casing with its axis of rotation lying along the longitudinal axis of the rear portion. Reciprocated by the motor via a drive transmission system is a cutter carrier mounted for reciprocatory movement in a bearing support structure. The cutter carrier carries a clamp by which a cutter is attached to the carrier. The carrier is reciprocated at a rate of between 4,000 and 12,000 movements per minute and with a stroke of from 4 to 12 mm for rapid cutting of thin material. The cutter may have a generally U-shaped blade.

摘要： A hand-held, fan-cooled motor drive jig saw with a two-piece, tiltable shoe assembly having a reversible, phenolic resin base portion with a wide recess for scrolling and a narrow recess for straight cuts. The base is connected to the shoe cover independent of the attachment of the cover to the saw housing to maintain a pre-selected tilt angle. Coolant air exhausted from the saw housing is channeled through flow passages in the shoe assembly to outlet ports in the shoe assembly to provide debris-clearing air streams oriented parallel to the workpiece surface and perpendicular to the cutting direction. The housing exhaust port is flow-connected to the shoe assembly through complementary sliding surfaces at the point of attachment.

摘要： A device for feeding a workpiece to the saw component of a sawing machine and for clamping the workpiece during the cutting thereof by the saw component, has first and second clamping jaws supported on a table of the sawing machine and cooperating with one another for immobilizing the workpiece; and a feed roller supported at the machine table in the zone of the clamping jaws for feeding the workpiece into the operational range of the saw component. The device further has an arrangement connected to the first clamping jaw for displacing the same towards and away from the second clamping jaw in a direction inclined with respect to the surface of the machine table. In this manner the first clamping jaw can be set at a relatively short distance from the surface of the machine table into a closed position in which it presses the workpiece against the second clamping jaw and further, the first clamping jaw can be set at a relatively large distance from the surface of the machine table into an open position in which it releases the workpiece. The device further has an arrangement coupled to the feed roller for moving the same into an operative position simultaneously with the displacement of the first clamping jaw into its open position and for moving the feed roller into an inoperative position simultaneously with the displacement of the first clamping jaw into its closed position. In the operative position the feed roller projects, at least partially, beyond the surface of the machine table for engaging and advancing the workpiece and in the inoperative position the feed roller is in a withdrawn state below the surface of the machine table.

摘要： The saw (10) includes a frame (12) having an opening (14) with a pair of proximate and distal blade retaining chucks (58, 60) located on respective sides of the opening (14). A saw blade (16) is retained between the pair of chucks (58, 60). A plurality of pulleys (32, 34, 36, 38) are attached in spaced relation to the frame (12) including pulleys (32, 34) on opposed sides of the opening (14). A flexible band (52) is entrained about each of the plurality of pulleys (32, 34, 36, 38), with the band (52) having a first end (54) operatively connected to the proximate blade retaining chuck (58) and a second end (56) attached to the distal blade retaining chuck (60). A reciprocating drive (72) is attached to the proximate blade retaining chuck (58). The reciprocating drive (72) and the flexible band (52) work in conjunction to pull the blade (16) in opposite directions during each cycle of the drive (72). An alternative embodiment of the present invention may take the form of a stationary table saw (fig. 7).

摘要： A reciprocating saw includes a system (10) that permits the saw blade to be mounted so that it is at an angle (i.e., so that it is not parallel) to the axis of reciprocation of the saw. The system (10) permits the blade (6) to be rotated about its axis of reciprocation, and in some embodiments the angle between the blade axis (B) and the axis of reciprocation of the saw (A) may be varied through an angle of about 90 .
