[0002] As the name suggests, the semicircle bar is a metal rod-shaped material with a semicircular cross section. Because the cross section is semicircular, the ordinary three-jaw chuck cannot determine the center of the circle when turning the outer circle, and it is more inconvenient to fix it. Usually, a four-jaw chuck is used for clamping.
When the four-jaw chuck is clamped, two semi-circular bars need to be processed together, which is convenient to find the center line, but the irregularity of the outer circle of the semi-circular bar and the non-self-centering clamping characteristics of the ordinary four-jaw chuck , resulting in too long clamping time, and for semicircular bars with a large total length, the firmness of the clamping cannot be guaranteed, and the claws are easy to come off

The invention discloses a semi-circular bar lathe fixture which comprises a boss chuck, a hollow cylinder, fastening bolts and movable tiles. The boss chuck comprises a circular shell and a center hole. The right end face of the boss chuck and the left end face of the hollow cylinder are connected into a whole. The upper portion of the hollow cylinder is provided with two threaded holes, and the lower portion of the hollow cylinder is provided with two threaded holes. The fastening bolts are matched with the threaded holes of the hollow cylinder. The movable tiles include an upper circular-arc-shaped tile, a lower circular-arc-shaped tile and locating blocks arranged on the reverse sides of the movable tiles. The centers of the locating blocks are matched with the bottoms of the fastening bolts. Through the method, the feature that the movable tiles can be dismounted and replaced is fully utilized. The pressure of the fastening bolts forces the tiles to tightly clamp a semi-circular bar. Therefore, the semi-circular bar lathe fixture is high in clamping speed, high in precision, good in fastness and suitable for turning large-scale semi-circular bars.
Description
technical field [0001] The invention relates to the field of lathe clamps, in particular to a semicircular bar lathe clamp. Background technique [0002] As the name suggests, the semicircle bar is a metal rod-shaped material with a semicircular cross-section. Because the cross-section is semicircular, the ordinary three-jaw chuck cannot determine the center of the circle when turning the outer circle, and it is more inconvenient to fix it. Usually, a four-jaw chuck is used for clamping. When the four-jaw chuck is clamped, two semi-circular bars need to be processed together, which is convenient to find the center line, but the irregularity of the outer circle of the semi-circular bar and the non-self-centering clamping characteristics of the ordinary four-jaw chuck , resulting in too long clamping time, and for semicircular bars with a large total length, the clamping firmness cannot be guaranteed, and the claws are easy to fall off. Contents of the invention [0003] Th...
