Internal-and-external tooth structure machining device of tooth-shaped linings

The invention provides an internal-and-external tooth structure machining device of tooth-shaped linings. The internal-and-external tooth structure machining device comprises a pressing plate, a mainbody, a positioning ring and a positioning clamp. The positioning ring can move axially in a central through hole of the main body and can be detachably fixed to the side wall of the main body. The pressing plate is detachably fixed to the top of the main body and used for pressing tooth-shaped lining blanks. The main body can be detachably fixed into the positioning clamp. According to the internal-and-external tooth structure machining device, clamping is convenient, positioning is accurate, linear cutting machining of large-batch and small-batch flexible adjusting of the tooth-shaped linings can be achieved. 本发明提供的种齿形衬套的内外齿结构加工装置包括压板、主体和定位圈和定位钳；所述定位圈能够在所述主体的中央通孔内沿轴向活动、并能够可拆卸固定于所述主体的侧壁上，所述压板可拆卸固定于所述主体顶部，用于对齿形衬套料坯进行压紧；所述主体能够可拆卸固定于所述定位钳内。本发明加工装置，装夹便利，定位精准，可以实现齿形衬套大、小批量灵活调整的线切割加工。
