Abstract

The invention discloses a lathe saddle, which comprises a tool installation seat, a fixed base and a movable base, wherein one end of the movable base is arranged on the fixed base through a bearing; the axis of the bearing is vertical to the fixed base; a circular-arc guide rail is arranged between the fixed base and a movable guide rail; the revolving central line of the circular-arc guide rail is superposed with the axis of the bearing; the tool installation seat is arranged on the movable base; the movable base is provided with a master form contact installation seat; the fixed base is provided with a master form contact retaining piece; and a spring is arranged between the master form contact retaining piece and the master form contact installation seat. In the lathe saddle, the fixed base and the movable base are adopted, the movable base can rotate around the bearing at one end, and the circular-arc guide rail is arranged between the fixed base and the movable base for supporting the movable base; and a master form contact clings to a master form under the action of the acting force of the spring, and the motion locus of the master form contact is decided by the shape of the master form, so that processing of a noncircular part is realized.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a lathe used for processing non-circular contour parts, in particular to a lathe tool holder. Background technique [0002] The improvement of the performance and quality of mechanical products is inseparable from the progress of design technology and manufacturing technology. In recent years, non-circular designs have been widely used in some product designs. For example, the design of the piston has generally adopted the design of the key parts of the outer surface, which are convex to elliptical, and special-shaped pin holes. Non-cylindrical turning technology has become one of the key technologies for turning design into products in this technology, and its development process is divided into the following three stages: (1) The processing stage of mechanical motion synthesis. The mechanical motion synthesis method generates the turning trajectory of the special-shaped oute...
