PLThe patent description was published: March 15, 1982 112551 Int. Cl.2 B24B 19/16 B21G 1/08 OR, at LNIA fltonj I "-" Inventors: Jan Kaniewski, Wieslaw Ponder. Authorized by the patent: Factory of Surgical and Dental Tools " Mrfam ", Milanówek (Poland) The invention's Poszedirntioteim grinding machine is designed especially for grinding the blades of medical needles. Known grinders used for grinding medical needles are equipped with a single spindle on which a grinding wheel for surface finishing is mounted. Grinding needles with needles (in these grinders is inefficient because the entire grinding operation is performed with a tool intended for finishing machining. Using several grinders with different abrasives requires the transfer of the holder with treated needles from one machine to the other, and this increases the preparation time is so much that the machining becomes very costly. Moreover, the accuracy of workmanship is reduced. The use of the known multi-spindle grinders for the grinding of medical needles requires the use of complicated machining holders, the additional inconvenience of which is a small amount needles mounted in the holder. The grinder according to the invention is equipped with two pull screws with axes parallel to the axis of the spindles and different directions of rotation, on which holders for ground needles are placed. Placed in the needle holders while moving the holder through the pulling screw, Closer to the headstocks, they are sharpened and when moved At the handle, the sharpened needles are removed from the handle by the second pull screw and loaded, intended for sharpening. The subject of the invention is shown in the example of the grinding machine shown in the drawing, in which fig. 1 shows a side view, fig. 2 - a view from 3, 4 and 5, the spindle axes are parallel to each other on the bed and the grinding machines. The direction of rotation of the spindles 2, 3, 4 and 5 is different, and the abrasive dams mounted on the spindles have different hardness and structure. Parallel to the axis of the spindles of the headstocks 2, 3, 4 and 5 are placed in the bed two screws There are 6 and 7 holders on which holders 8 are mounted for needle packets, and at the ends of bolts 6 and 7 there are hydraulic gears 9 and 10 intended for moving holders 8 from bolts 6 to 7 and vice versa. the needle pack in the holder 8 the pull screw 6 moves the holder along the headstocks 2, 3, 4, 5 parallel to the axis of their spindles. When the needle holder 8 is moved, the needles are sharpened. When the handle 8 is moved to the end of the thread 6, the conveyor 10 is placed on the screw 7, which moves it in the opposite direction. When the handle 8 on the screw 7 is moved, the needle pack is removed from the holder 8 and the packet is placed therein. needles for sharpening 112 5513 112 551 4 sharpening needles *. When the handle 8 is moved to the end of the screw 7, the conveyor 9 is placed on the screw 6, which by displacing it causes sharpening of the needle packet fixed in it. Placing several handles 8 on the screws 6 and 7 increases the sharpening efficiency. for transporting the handle with needles and moving them during the entire grinding process of all surfaces of the needle blades, has contributed to the reduction of the processing time, the reduction of the number of defects and the improvement of the accuracy and quality of the needle finish. According to the invention, the grinder allows the use of such The directions of rotation of grinding wheels of different hardness and structure, which enable roughing and finishing, and remove burrs from the blade surface, also prevent the possibility of burrs from penetrating into the tube holes.
