在右图所示的差速器壳体中,两部分球面的直径公差为一般要求,形位公差的要求较严。 在批量生产中,我厂是在数控立钻上采用图中所示刀具来加工这一对称球面。其中刀杆上端与立钻主轴牢固连接,工作时,刀杆下端插入定位套中。刀杆以销带动刀头旋转和上下运动并分别切削两球面。 数控立钻加工球面有以下特点: (1)工件下端套在定位套上,从而保证了球面与 In the case of the differential housing shown on the right, the diameter tolerances of the two-part spherical surfaces are the general requirements and the requirements of the form-fitting tolerances are more stringent. In mass production, our factory is in the use of CNC drilling legislation shown in the tool to process the symmetrical spherical. The upper end of the arbor is firmly connected with the vertical spindle, and the lower end of the arbor is inserted into the positioning sleeve during work. Arbor to drive the cutter head rotation and up and down movement and cutting two spherical. CNC vertical drilling spherical processing has the following characteristics: (1) the lower part of the sleeve in the positioning sleeve, thus ensuring the spherical and
