Ejector pin sliding mechanism of numerical control lathe

Abstract

The utility model discloses a numerical control lathe thimble sliding mechanism which comprises a base, a sliding groove is formed in the surface of one end of the top of the base, a sliding block is connected in the sliding groove in a sliding mode, a fixing plate is installed on the top of the sliding block through a screw, and a bearing seat is installed on one side of the sliding block through a screw. An adjusting screw rod is installed on the surface of one end of the base through a reserved threaded hole, the end, located in the sliding groove, of the adjusting screw rod is fixed into a rotating ring of the bearing seat through a flat key, and a guide hole is formed in the end face, away from the adjusting screw rod, in the sliding groove. According to the ejector pin sliding mechanism of the numerical control lathe, the adjusting screw rod is connected with the base through the threads, and the sliding block has good stability when the adjusting screw rod does not receive steering force, so that after the position of the sliding block is determined, other fastening mechanisms are not needed to fix the position of the sliding block; therefore, components of the ejector pin sliding mechanism are simplified, using convenience is improved, and the ejector pin sliding mechanism is suitable for wide application and popularization.
