Machining method of semi-rigid cable part

Abstract

The invention discloses a machining method of a semi-rigid cable part, and the method comprises the following steps: 1. designing a dedicated thread sleeve, wherein the dedicated thread sleeve comprises a threading die, a threading die lock sleeve and a taper sleeve; when the dedicated thread sleeve is used, the threading die is put into the front end of the threading die lock sleeve and is locked by virtue of bolts; a round hole on the front end of the taper sleeve and the optical axis of the rear end of the threading die lock sleeve are matched; the angle of the taper shank of the rear end of the taper sleeve is matched with the conical degree of a machine tool tailstock; 2. putting the semi-rigid cable part into a lathe spindle clamping tank to expose required machining length; 3. putting the taper sleeve into the machine tool tailstock, clamping the threading die by the lock sleeve, pushing the machine tool tailstock to cause the threading die to be cut into the part, manually sheathing threads, and stopping machining on the position 3-5mm in front of the part; 4. cutting a scratch of which the depth is 0.15mm on a circumferential surface with the required machining length by virtue of a cutter; 5. slightly rocking the handwheel of the machine tool tailstock; and causing the metal copper tube of the cable part to be totally separated from a non-metal sandwich by the part under the acting force of the axial tension force of the dedicated thread sleeve so as to finish machining the semi-rigid cable part.

Description

technical field [0001] The invention relates to a processing method of cable parts, which is especially applied in the processing of semi-rigid cables made of composite flexible materials, and can be popularized and used in other rotary parts of similar materials. Background technique [0002] Semi-rigid cables consist of composite flexible materials. The traditional processing method is to remove the outer layer of copper with an outer circular turning tool. Since the interlayer of the part is a non-metallic material, the outer metal layer is only 0.1-0.5mm. Because the part is slender, soft, and poor in straightness, the conventional method When the metal layer is removed, there are obvious traces of the knife on the surface of the non-metal layer, causing the parts to bend, jump and deform. The production efficiency is low, the scrap rate is high, and it is difficult to meet the accuracy requirements of the design drawings. Contents of the invention [0003] The techn...
