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： The present invention relates to a polishing holder removing device for a grinder that allows a grinding tool to be simply coupled/decoupled to/from a coupler, which is mounted on a rotary shaft of a body of a hand grinder and is rotated at a high speed, and that can ensure anti-vibration, stability, continuity, and smooth transmission of power in grinding by more firmly coupling the grinding tool to the coupler. The present invention includes a grinding tool, a coupler, a sleeve, locking balls, a spring, and a cap nut, in which a cylindrical shank, a groove, and a rectangular shank are sequentially formed at an end portion of a body of the grinding tool; the coupler has a seating hole and a rectangular hole where the grinding tool is fitted and fixed, a threaded-hole for fastening to a grinder body, and a flange having two lines of through-holes formed around the outer side; a lower dustproof groove having a step and a seating groove are formed at a side in the sleeve, and an upper dustproof groove is formed at the other side in the sleeve; the locking balls are disposed in the ball holes formed in the coupler and moved toward/away from the cylindrical shank and the groove of the grinding tool when the sleeve moves so that the grinding tool can be fixed or released; the spring applies elasticity when the sleeve slides; and the cap nut retains the sleeve.
摘要翻译：本发明涉及一种用于研磨机的抛光保持器移除装置，其允许将研磨工具简单地耦合/去耦合到耦合器/耦合器，该耦合器安装在手动研磨器的主体的旋转轴上并且以高的速度旋转速度，并且可以通过将研磨工具更牢固地联接到联接器来确保抗振动，稳定性，连续性和平稳地进行磨削中的动力传递。本发明包括研磨工具，联接器，套筒，锁定球，弹簧和盖帽螺母，其中圆柱形柄，槽和矩形柄部顺序地形成在主体的端部处研磨工具; 联接器具有座孔和矩形孔，其中研磨工具被安装和固定，用于紧固到研磨机主体的螺纹孔和具有围绕外侧形成的两条通孔线的凸缘; 在套筒的一侧形成具有台阶和底座的下部防尘槽，并且在套筒的另一侧形成有上部防尘槽; 当套筒移动时，锁定球设置在形成在联接器中的球孔中并且朝向/远离圆柱形柄和磨削工具的槽移动，使得研磨工具可以被固定或释放; 当套筒滑动时，弹簧施加弹性; 并且盖螺母保持套筒。
