Machining process of special-shaped shaft containing long swing arm

Abstract

The invention provides a machining process of a special-shaped shaft containing a long swing arm. The machining process of the special-shaped shaft containing the long swing arm comprises the following steps: S1, selecting a bar material which can contain the maximum shape of a whole special-shaped shaft workpiece containing the long swing arm, and carrying out rough turning to obtain an eccentric shaft; S2, machining a next bar material, enveloping the shape of the special-shaped shaft workpiece containing the long swing arm, and carrying out rough turning on the eccentric shaft; S3, respectively carrying out finish turning on an outer circle, an inner hole and a chamfer at two ends of the special-shaped shaft workpiece containing the long swing arm to required sizes; and S4, clamping the special-shaped shaft workpiece containing the long swing arm to a right direction by using a clamp, namely, enabling the axis of the part to be perpendicular to a working table, and milling the shape and a square hole of the special-shaped shaft workpiece containing the long swing arm by using NC machining. According to the invention, high efficiency is achieved through turning machining, and the machining process of the special-shaped shaft containing the long swing arm plays an important role in the coaxiality of the inner circle and the outer circle, the perpendicularity of the two end faces to the axis, the perpendicularity of the long arm large plane to the axis, rapidly positioning and alignment of a workpiece to be machined through the arranged clamp, and improving the NC machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of special-shaped shaft processing technology with long swing arm, and in particular relates to a special-shaped shaft processing technology with long swing arm. Background technique [0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into optical shafts, stepped shafts and special-shaped shafts. There are three types of shafts; or divided into solid shafts, hollow shafts, etc. In industrial products, shaft parts are suitable for maintenance operations of one or more CNC machine parts. They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. Shaft parts are rotating parts whose length is greater than the diameter. They are generally composed ...

Problems solved by technology

[0003] Special-shaped shaft parts with long arms, such as figure 1 and figure 2 As shown, it is usually made of stainless steel. The rough-turned round bar or rectangular material is milled with two outer circles, inner round holes, square holes, and chamfers at one end in turn with a machining center, and then turned around. After secondary assembly Clamping, making a watch to align, milling the two outer circles, inner holes, and chamfers at the other end, survival, high coaxiality requirements are not easy to guarantee, the milling amount is large, the survival speed is relatively slow, and processing is extremely inconvenient
