Example Embodiment

[0024] Example 1: Such as Figure 1~4 The tool shown for turning and milling includes a chuck connecting piece and a step positioning shaft. The chuck connecting piece is sequentially arranged along the same axis with a connecting piece chassis 1 and a connecting piece boss 2 of a flange structure, and The outer diameter becomes smaller successively, and a clamping hole 4 for clamping and positioning the claw is opened along the axis of the chuck connector. The step positioning shaft is sequentially arranged with a cylindrical structure positioning shaft chassis 7, positioning shaft boss 8 and a core shaft 9 along the same axis, and the outer diameter of the core shaft 9 becomes smaller than that of the workpiece to be processed. If the inner diameters are the same, the workpiece to be processed can be sleeved on the mandrel 9 in an interference fit manner. In addition, a positioning block can be installed on the upper surface of the mandrel 9. The positioning block is screwed...

Abstract

The invention discloses a tooling for turning and milling, which includes a chuck connector and a stepped positioning shaft. The diameter becomes smaller in turn, along the axis of the chuck connector, there is a through-clamping hole for the clamping and positioning of the gripper; the stepped positioning shaft is sequentially arranged with a cylindrical positioning shaft chassis along the same axis, and positioning Shaft bosses and mandrels, and their outer diameters become smaller in turn, the outer diameter of the mandrel is consistent with the inner diameter of the workpiece to be processed, the outer diameter of the positioning shaft boss is larger than the inner diameter of the workpiece to be processed, and smaller than the outer wall of the workpiece to be processed The bottom diameter of the upper sealing groove; the stepped positioning shaft is fixed on the chuck connector, and the workpiece to be processed is set on the mandrel at the front end of the stepped positioning shaft. The outer cylindrical surface and sealing groove can be processed in one clamping, which can reduce the processing accuracy requirements of the inner hole of the finish car while ensuring the coaxiality requirements of each other.

Description

technical field [0001] The invention relates to the field of mechanical processing tooling, in particular to a tooling for turning and milling. Background technique [0002] In the field of machinery, for components with notch-shaped sealing groove structures uniformly distributed on the outer surface of the ring, in order to ensure that the seal is fitted on the ring to achieve a better sealing effect, in the design stage of the drawing, the Between the outer cylindrical surface of the part and this type of sealing groove, higher coaxiality design requirements are often given. [0003] In the previous processing method, the inner cylindrical surface is firstly turned on a lathe, and then the outer cylindrical surface is finished, and then the sealing groove is milled on a milling machine. In the processing process, in order to ensure that the outer cylindrical surface of the finished workpiece and the sealing groove meet the coaxiality requirements of the design, the proce...
