摘要： A saw blade clamping arrangement (500) for a power tool (10) includes a clamp support (502), a biasing member (538) and an actuation member. The clamp support (502) is interconnected with the drive shaft (30) for reciprocating motion with the drive shaft (30) relative to a housing of the power tool (10). The clamp support (502) is configured to selectively receive a saw blade (38) of the power tool (10) in various orientations. A release lever (532) is carried by the housing and is manually rotated to move a control member (504) between a first position in which the saw blade (38) is coupled to the drive shaft (30) and a second position in which the saw blade (38) may be displaced from the drive shaft (30). In at least one of the orientations, the saw blade (38) is positioned offset from the drive shaft (30) and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

摘要： An apparatus (10) is provided that allows a working element to undergo either rotary or reciprocating motion via a transmission system (12) that is very compact in terms of the amount of space it requires to convert the rotary output of the motor (24) into either rotary or reciprocating output of an output shaft (25) operably connected to the working element. The apparatus (10) has a barrel cam transmission including input (26) and output (28) members between which a clutch (30) and cam mechanism (22) are disposed for providing a rotary/reciprocating transmission system (12) with a compact design. The transmission (12), and in particular the clutch (30) and cam mechanism (22) thereof, has a sturdy construction to allow it to withstand shock forces such as axial loading that may be placed on the working element and transmitted to the transmission system (12) during tool operations without disruption of the same.

摘要： Dispositif de retenue de poinçon (20) amélioré dans lequel une plaque d'appui (24) s'étend sur une surface relativement grande pour dissiper la force émanant d'un poinçon (64). Un corps de retenue (22) et la plaque d'appui sont reliés l'un à l'autre de façon permanente et comportent des passages (38, 40, 42, 44 et 46) qui sont finalement meulés après avoir été fixés à demeure. Ce dispositif permet d'avoir des passages dans la plaque d'appui et dans le corps de retenue bien alignés durant la constitution du dispositif de retenue de poinçon. Comme la plaque d'appui dissipe la force sur une surface relativement grande, le dispositif de retenue de poinçon peut être utilisé dans des conditions plus sévères que les dispositifs de retenue de poinçon de l'art antérieur. Un passage de ressort (56) est fermé par un élément étanche (79) inséré dans la plaque d'appui, ce qui permet l'utilisation de ressorts standard (82).

摘要： A tool change apparatus for a machining center and the like comprises a spindle head (2) slidably mounted on a column (1), and a spindle (7) rotatably mounted in the spindle head (2). The spindle has at the lower end thereof a tapered tool reception bore (15) in which a tool (16) is releasably held. When a draw bar (17) is shifted upwards, resilient clamper arms (24) are forced to enter a reduced bore (14a) to be contracted thereby so that a head (16a) of the tool is clamped. When the draw bar is shifted downwards, engageable end portions (24a) are moved into an enlarged recess-like portion (14d) whereby the clamper arms (24) are allowed to expand outwards to release the head (16a) of the tool. Even when the head is released, a stop pin (33) urged by a spring (34) continues to engage the head of the tool whereby the tool is still held by the spindle.
Tools are held by a series of magazine pots (36). Each pot is indexed to a tool change station (B). A tool change shaft (60) has two oppositely extending pairs of tool change (68) which function to transfer tools between an indexed tool pot and the spindle.
摘要翻译：用于加工中心等的刀具更换装置包括可滑动地安装在柱（1）上的主轴头（2）和可旋转地安装在主轴头（2）中的主轴（7）。主轴在其下端具有锥形工具接收孔（15），工具（16）可释放地保持在其中。当拉杆（17）向上移动时，弹性夹持臂（24）被迫进入减小的孔（14a）以被收缩，从而夹紧工具的头部（16a）。当拉杆向下移动时，可接合的端部部分（24a）移动到扩大的凹进部分（14d）中，从而允许夹持臂（24）向外扩张以释放工具的头部（16a）。即使当头被释放时，由弹簧（34）推动的止动销（33）继续接合工具的头部，由此工具仍然被主轴保持。工具由一系列杂志罐（36）持有。每个锅被索引到换刀站（B）。工具更换轴（60）具有两对相对延伸的工具更换对（68），其可用于在分度的工具箱和主轴之间传送工具。
