在车床上加工带有多个内球面的工件,找正、装夹都很麻烦。为此,我们设计了一个在万能铣床上,用立铣头加工内球面的刀具。工件装夹在工作台上,通过工作台的移动,找正球面中心(必须使定心轴中心与工件上平面相吻合),即可加工出标准的内半球面。如图所示,将铣杆9装在立铣头8锥孔内,在立铣头8端面固定一连接板11,装上溜板13及丝杆12、螺母14.转动手轮10,通过丝杆12、螺
In the lathe machining with multiple inner spherical workpiece, to find positive, the clamping is very troublesome. To this end, we have designed a universal milling machine, milling the inner surface of the cutter head. The workpiece is clamped on the workbench. Through the movement of the workbench, find the center of the spherical surface (the center of the centering shaft must coincide with the plane on the workpiece) to form the standard inner hemispherical surface. As shown in the figure, the milling rod 9 is installed in the milling head 8 tapered bore, the end face of the milling head 8 is fixed to a connecting plate 11, fitted slide plate 13 and screw 12, nut 14. Turn the hand wheel 10, through Screw 12, screw
