摘要:
The present invention relates to a device that enables a polishing disk which is consumable goods used for cutting, polishing and grinding an object in a state of being fixed to a rotary shaft of a grinder body to be easily attached to or detached from a hand grinder in a simple way. In addition, the device prevents the polishing disk from being separated from the grinder in the middle of work, reducing vibration. The device includes: a grinder body including a rotary shaft which is driven by an operation of electric motor or air pressure; a power-transmitting member that includes catching protrusions protruding from a top end of a main body of the power-transmitting member, a flange formed below the catching protrusions, and a hexagonal pillar formed below the flange and that is fixed to the rotary shaft of the grinder body by a fixing bolt; a stopper body including a hexagonal hole that is formed at the center of the stopper body to receive the power-transmitting member therein, and arc-shaped mounting grooves that are formed at the outside of the hexagonal hole to face each other; an upper rotary plate and a lower rotary plate that are mounted on a top of the stopper body; and a disk holder that includes an upper fixing ring and a lower supporting plate which are provided to fix an abrasive therebetween and that is assembled with the power transmitting member.

Die Erfindung betrifft ein System umfassend ein Teller-Werkzeug (50) und eine Hand-Werkzeugmaschine (10) in Gestalt eines Schleif- oder Poliergeräts, das eine Werkzeugwelle (17) und einen Antriebsmotor (12) zum Dreh-Antreiben der Werkzeugwelle (17) um eine Drehachse (15) aufweist, wobei das System eine Halteanordnung (80) mit einer Werkzeughalterung (30) an der Werkzeugwelle (17) und einer Maschinen-Halterung (60) an dem Teller-Werkzeug (50) umfasst, wobei die Werkzeughalterung (30) und die Maschinen-Halterung (60) einen Steckvorsprung (31) und eine Steckaufnahme (61) aufweisen, die ineinander steckbar sind, so dass eine Drehmitnahme-Außenumfangskontur (40) des Steckvorsprungs (31) formschlüssig und drehfest an einer Drehmitnahme-Innenumfangskontur (70) der Steckaufnahme (61) anliegt, wobei die Außenumfangskontur (40) und die Innenumfangskontur (70) eine im wesentlichen runde Basiskontur (41, 71) umfassen, an der tangential seitlich Drehmitnahme-Abflachungen (42, 72) zum drehfesten Eingriff vorgesehen sind. Bei dem System ist vorgesehen, dass an einem sich zwischen den Drehmitnahme-Abflachungen (42, 72) erstreckenden Drehmitnahme-Abschnitt der Drehmitnahme-Außenumfangskontur (40) mindestens ein vor die runde Basiskontur (41, 71) vorstehender Drehmitnahme-Vorsprung (43) zum Eingriff in eine zwischen den Drehmitnahme-Abflachungen (42, 72) der Drehmitnahme-Innenumfangskontur angeordnete Drehmitnahme-Ausnehmung vorgesehen ist.
摘要:
A power tool comprises a housing, a motor (2) mounted in the housing and having a rotary spindle (4), a trigger (20) configured for switching on/off the motor (2), a support member (10) fixed to the housing, and a spindle lock (40) configured to be actuated to move in a first radial direction (Rl) to lock the spindle (4) and a second opposite radial direction (R2) to release the spindle (4). When the trigger (20) is switched on, it moves the spindle lock (40) in a first axial direction (Tl), and when the trigger (20) is switched off, the spindle lock (40) is allowed to move in a second opposite axial direction (T2). The spindle lock (40) has a positioning member (44) which cooperates with a stop portion (12) of the support member (10) to prevent the power tool from being switched on and being locked at the same time.
摘要:
A plate locking mechanism for a surface preparation device comprising a connecting plate having a receiving aperture, a base plate and a floating plate capable of being substantially aligned with the base plate. A fastener extends through a floating plate aperture and engages with a base plate aperture and a resilient member is operatively associated with the fastener to maintain the floating plate in contact with the base plate and wherein, when the base plate is located within the receiving aperture, the floating plate is rotatable to retain the connecting plate in position.
摘要:
In a power tool 1 in which a disc-shaped tool is attached to a spindle (16) that protrudes from a housing (10, 15) in which a motor M is housed. A dust-collecting cover (20) provided on the housing (10, 15) for covering the disc-shaped tool has a tool insertion opening (24B). A rotation stopping tool (25) that stops rotation of the spindle (16) can be inserted into the dust-collecting cover (20) through the tool insertion opening (24B). The duct-collecting cover (20) is provided with a rubber ring (26) that blocks the tool insertion opening such that the tool insertion opening can be opened and closed as desired.
