する工作機械用棒材振止め装置。An operating shaft 2 which passes through the upper bearing part of the bracket 1 fixed upright on the base surface and extends parallel to the bar delivery center line and has a rotating means attached thereto; an upper horizontal seat part 3' that is connected to the arm 3 which is fixed in contact with the arm 3 and forms a semi-coaxial structure that is perpendicular to the operating axis and centered on the bar support center; In this case, connect the lower horizontal seat part 1' forming a semi-coaxial half that becomes a full circle, and connect two points equidistant in the radial direction from the center of the semicircular ring on the outer surface of both horizontal seat parts on a line parallel to the semi-coaxial mating surface. , four pulley shafts 4 attached with movement adjustment means along the - line and mounted with their axes parallel to the bar delivery center line; A pulley 10 which is made of a material and has an outer ring 10' having a large number of rows of round grooves on its outer periphery is fitted and bonded to its outer diameter, and an outer circle perpendicular to the parallel line of the pulley shafts 4 of both horizontal seats. A pair of tensioning pulley shafts 12 fixed to each other parallel to the axis of the pulley shaft 4 at equidistant positions from the center point of the ring, and a cylinder rotatably fitted to the tensioning pulley shafts and made of the same material as the outer ring 10'. The tension pulley 13 is formed by fitting and bonding the outer ring, and the tension pulley 13 is stretched through the outer periphery of the pulley 13, which is tensioned in the outer periphery groove of the outer ring 10' of the two pairs of boots 1J10 in order to bend and support the rotating bar 16 by fitting it into the tension pulley 13. The unit, which includes a large number of belts 14 having high elasticity and toughness, and which can be opened and closed by swinging the upper transverse seat part 3' by rotation of the operating shaft, is placed in a position extending rearward of the center line of the main shaft of the main engine, and the two transverse seat parts are aligned. A bar steadying device for machine tools that is constructed by arranging multiple sets of horizontal or vertical surfaces at different angles.
