Abstract
The utility model discloses an internal and external circle coaxiality lathe machining tool for a workpiece, consisting of a clamping body, a tightening piece, a baffle adjacent to the tightening piece and a tightening bolt penetrating through the baffle. The clamping body sequentially consists of a machine tool principal axis matching section, a transition section, a workpiece mounting section and a conical section, wherein the diameter of the transition section is the greatest, and the end part of the conical section is provided with a bolt hole adaptive to the tightening bolt. The tightening piece consists of more than three tightening blocks which have the same structures and gaps and elastic rings which are arranged on the excircle surfaces of the tightening blocks, wherein each tightening block is provided with a high-precision internal annulus which is adaptive to the conical section of the clamping body and a high-precision excircle annulus which is adaptive to the inner circle of the workpiece after being tightened, and the middle of the excircle annulus of each tightening block is provided with a ring slot for placing the elastic rings. By adopting the structure, the internal and external circle coaxiality of the machined workpiece can meet the precision requirement, the qualification rate of machining is improved, and the machining cost is reduced.
