    • The present utility model relates to a twin saw blade cutter, improves upon the existing foundation of inner and outer saw blades, small and large output shafts, first and second gearwheels and a power gear shaft, etc., in that the small output shaft is designed with a first annular locking groove and a second annular locking groove located between the first and second gearwheels, a first locking spring which presses against a fifth bearing is mounted in the first annular locking groove, a second locking spring is mounted in the second annular locking groove, and at the same time a flexible piece which arches towards the side of the second locking spring is further sleeved on the small output shaft, the two ends of the flexible piece pressing against the second gearwheel and the second locking spring respectively. After adopting the above solution, it is possible to not only prevent outward protrusion of the small output shaft, but also prevent retraction of the small output shaft, and at the same time absorb the cumulative manufacturing tolerance of the various components and preload the small output shaft in the axial direction, thereby ensuring coincidence of the axial positions of the two shafts such that the inner saw blade has a limited amount of space for sliding movement left and right, and ensuring that there is an appropriate gap between the two saw blades at all times, such that the cutting operation may proceed smoothly and reliably.
    • 本实用新型涉及一种双锯片切割机,改进了现有的内外锯片,小型和大型输出轴,第一和第二齿轮和动力齿轮轴等的基础,因为小输出轴是 设置有位于第一和第二齿轮之间的第一环形锁定槽和第二环形锁定槽,压靠第五轴承的第一锁定弹簧安装在第一环形锁定槽中,第二锁定弹簧安装在第二环形锁定槽中 锁定槽,并且同时朝向第二锁定弹簧的侧面弯曲的柔性件进一步套在小输出轴上,柔性件的两端分别压靠第二齿轮和第二锁定弹簧。 在采用上述方案之后,不仅可以防止小输出轴的向外突出,而且可以防止小输出轴回缩,同时吸收各种部件的累积制造公差并预加载小输出 轴,从而确保两个轴的轴向位置的一致,使得内锯片具有有限量的用于左右滑动的空间,并且确保两个锯片之间存在适当的间隙 所有的时间,使得切割操作可以平稳和可靠地进行。

    • Une paire de lames de scie comporte deux lames de scie (1, 2) disposées adjacentes l'une à l'autre et destinées à effectuer un trait de scie dans une pièce à usiner (5), conjointement et en coopération lors d'un mouvement de rotation s'effectuant dans des directions contrarotatives. Selon la présente invention, les dents (3, 4) des lames de scie (1, 2) présentent une inclinaison spécifique pour chaque lame (1, 2) au niveau de la partie tranchante des dents correspondantes (3, 4). Les dents (3, 4) d'une paire de lames de scie peuvent ainsi entrer en contact, à titre de première partie, avec une pièce à usiner, avec la partie de chaque dent (3, 4) la plus proche de la lame (1, 2) agissant conjointement, imprimant ainsi une force destinée à déplacer les lames (1, 2) l'une vers l'autre. Lors de l'ajustage des dents de scie (3, 4), on place les dents (3, 4) de chaque lame (1, 2) dans une direction latérale seulement, et dans une direction contraire au plan destiné à former un plan adjacent par rapport à la lame (1, 2) agissant conjointement. Les lames de scie (1, 2) qui forment une paire de lames de scie sont de préférence munies d'un organe destiné uniquement à faciliter la fixation des lames (1, 2) dans une relation adjacente l'une par rapport à l'autre, les lames (1, 2) étant placées l'une par rapport à l'autre selon une disposition relative correcte du point de vue de leur direction vers l'intérieur.

    • 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.
    • 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。
