    摘要： The invention relates to a quick-change system for a double-sided grinding disc, in which the grinding disc has a disc body which is provided on both sides with at least one separate grinding element. The grinding disc is robust and configured for grinding floors, walls or ceilings by means of a grinding machine. The quick-change system provides a grinding disc having an interface with a central through-hole, in which driver recesses are provided around the through-hole. Furthermore, the quick-change system provides an adapter with a bearing surface and a design which corresponds with the interface of the grinding disc. The quick-change system is advantageous, because only a single screw has to be loosened in order to reverse the double-sided grinding disc. In addition, the quick-change system is robust due to the design of the at least one driver, which is preferably provided with a concave driver profile segment.

    摘要翻译： 本发明涉及一种用于双面研磨盘的快速更换系统，其中该研磨盘具有盘体，该盘体在两侧上设有至少一个单独的研磨元件。 研磨盘结实耐用，并且配置为通过研磨机研磨地板，墙壁或天花板。 该快速更换系统提供了具有与中心通孔的界面的研磨盘，其中在通孔周围设置有驱动器凹槽。 此外，快速更换系统提供了一个适配器，该适配器具有一个支承面和一个与磨盘界面相对应的设计。 快速更换系统是有利的，因为只有一个螺丝必须松开才能翻转双面研磨盘。 此外，由于所述至少一个驱动器的设计，所述快速更换系统是坚固的，所述至少一个驱动器优选设置有凹形的驱动器轮廓段。

    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.

    摘要翻译： 本发明涉及一种能够将固定在研磨机主体的旋转轴上的状态下用于切削，研磨和研磨物体的消耗品的抛光盘，以便容易地附着到手动磨碎机 以简单的方式。 此外，该装置防止抛光盘在工作中间与研磨机分离，从而减少振动。 该装置包括：研磨机主体，包括由电动机或空气压力的操作驱动的旋转轴; 动力传递构件，其包括从动力传递构件的主体的顶端突出的捕获突起，形成在捕获突起下方的凸缘和形成在凸缘下方的六边形柱，并且固定到旋转轴的旋转轴 研磨机主体通过固定螺栓; 具有六角形孔的止动体，该六角形孔形成在所述止动体的中央，以容纳所述动力传递部件;以及弧形安装槽，所述弧形安装槽形成在所述六边形孔的外侧以彼此面对; 上旋转板和下旋转板，其安装在止动器主体的顶部; 以及盘保持器，其包括上固定环和下支撑板，所述上固定环和下支撑板设置成将磨料固定在其上并与动力传递构件组装。

    摘要： A mounting system (100) for mounting of a tool having a cylindrical cavity (161), the system comprising a shaft (111) having a key-zone (112) and a key (113) and a collar (114) against which a spring (115) can be positioned. The system comprises an adapter (150), with a seat (155) and a keyway (151) so that the drive shaft (110) can be slid into the adapter (150) and can be rotated therein when the driving shaft (110) is slid against the spring in the adapter (150). After rotation the key is blocked behind a shoulder in the recess.
