Method for machining oblique angle holes distributed in shaft parts

Abstract

The invention provides a method for machining oblique angle holes distributed in shaft parts. A flexible fixture composed of an angle plate, a V-shaped block and a part positioning and clamping device is adopted, wherein the V-shaped block is fixed on the angle plate through inner hexagon screws and cylindrical pins, and a V-shaped notch of the V-shaped block is in clearance fit with the outer circle of the part positioning and clamping device; the part positioning and clamping device comprises a drill plate, a pressure plate and a positioning plate, a hollow-shaft part is arranged above the positioning plate and is fitted to the same, the drill plate sleeves the hollow-shaft part, the pressure plate is arranged above the hollow-shaft part, the tail portion of a double-end bolt penetrates the pressure plate and the hollow-shaft part to be vertically and fixedly connected with the positioning plate, and the head of the double-end bolt is in threaded connection with a shouldered nut. The flexible fixture can be used repeatedly and can provide service to multiple machining objects, labor time can be saved, production efficiency can be improved, simplicity in operation is achieved, clamping is facilitated, and machining precision of the oblique angle holes is guaranteed.

Description

technical field [0001] The invention relates to a processing method for uniformly distributed oblique-angle holes of hollow shaft parts, which is used for processing uniformly distributed oblique-angle holes of hollow shaft parts. Background technique [0002] At present, the drilling of oblique angle holes on hollow shaft parts usually uses different tooling, so that multiple sets of fixtures need to be designed to meet the processing requirements, which not only wastes tooling and man-hours, but also produces the accumulation of errors in multiple positioning, resulting in difficult accuracy. achieve the desired effect. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a flexible fixture and a processing method for evenly distributing oblique holes in hollow shaft parts using the flexible fixture, which can realize high-precision machining of multiple oblique holes in hollow shaft parts. [0004] The object of the prese...
