Deformation process anchor clamps are prevented to thin wall gyration part

The utility model relates to a deformation process anchor clamps are prevented to thin wall gyration part belongs to cutting technical field. Physically the dingan dress is on the three -jaw (holding) chuck of lathe with anchor clamps during the turner excircle, and the work piece suit is on the anchor clamps body, and clearance fit, through screw nut, the conical surface interact of the conical surface of cone and elastic ring makes the elastic ring inflate to its excircle and work piece inner cylinder face in close contact with, compared with the prior art, the utility model, it is showing the advantage: strengthen thin wall gyration parts machining rigidity, reduced its clamping and warp with the cutting, guaranteed the machining precision. 本实用新型涉及种用于薄壁回转零件防变形加工夹具，属于切削技术领域。车削工件外圆时将夹具体定安装在车床的三爪夹盘上,工件套装在夹具体上，并间隙配合；通过螺杆螺母，锥体的锥面与弹性圈的锥面相互作用，使弹性圈胀大至其外圆与工件内圆柱面紧密接触，本实用新型与现有技术相比，其显著优点是：增强了薄壁回转零件加工刚度，减小其装夹和切削变形，保证加工精度。
