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

A kind of semi-rigid cable machining parts

Technical field

The present invention relates to a kind of processing method of cable components, especially be applied in the semi-rigid cable processing of composite and flexible material, can in the revolving parts of other similar materials, promote the use of.

Background technology

Semi-rigid cable is made up of the composite and flexible material.Traditional processing method is to remove outer copper sheet with the billmpse tool car; In view of the part interlayer is nonmetallic materials; Its appearance metal level is merely 0.1-0.5mm, because part is elongated, matter is soft, linearity is poor, when removing metal level with conventional method; The non-metallic layer surface has and significantly connects the tool marks mark, causes spares bend, beats and is out of shape.Production efficiency is low, and percent defective is high, is difficult to reach the required precision of design drawing.

Summary of the invention

Technology of the present invention is dealt with problems and is: the deficiency that overcomes prior art; The present invention adopts the method for directly sloughing outer copper sheet to process; Through the special screw thread sleeve; Make part in process, mainly bear axial force, overcome workpiece bending deformed that radial load that conventional processing method brings causes, guarantee the machining accuracy of part.

Technical solution of the present invention is: a kind of semi-rigid cable machining parts, and step is following:

The first step, the design special screw shell, described special screw thread sleeve comprises screw die, screw die lock sleeve and tapered sleeve, screw die are a kind of cutters of threading, with the screw die screw die lock sleeve front end of packing into, use screw lock during use; Tapered sleeve front end circular hole and screw die lock sleeve rear end optical axis match, and tapered sleeve rear end taper shank angle matches with the tail stock tapering;

Second step, the semi-rigid cable part is packed in the lathe spindle folder jar, expose the length of required processing;

The 3rd step, the tapered sleeve tail stock of packing into,, pass tail stock with lock sleeve clamping screw die, make screw die incision part, manually cover system screw thread stops to process when being worked into part front end 3～5mm place;

In the 4th step, cut the dark cut of 0.15mm at the circumferential surface of required processing length with cutting knife;

In the 5th step, jog tail stock handwheel, part under the effect of tightening force, make the metal copper pipe of cable components break away from nonmetal interlayer fully in the special screw thread quill, accomplish the processing of semi-rigid cable part.

Operation principle: the tapered sleeve tailstock tool of packing into; With the screw die that screw die lock sleeve clamping is fit to, make it on part, overlap the system craft thread, again with self-centering cutting knife incision respective depth; Reserve needed length; Shake tailstock then gently, make the metal copper pipe slowly extract nonmetal interlayer, reach and break away from fully till its surface.

The present invention compared with prior art beneficial effect is:

(1) the present invention adds man-hour, and part mainly bears axial clamping force, and radial force is small ignores, and compares with directly on lathe, clamping the effect of turning force in radial in the conventional method, and part is indeformable basically;

(2) the present invention adopts the anchor clamps of being made up of tapered sleeve, lock sleeve and screw die, and is simple in structure, make easily, and easy to use;

(3) the part smooth in appearance that processes of the method does not leave any revolution mark, does not have distortion, bending etc., and qualification rate reaches 100%, and production efficiency has improved more than 10 times.This processing method steady quality, reliable reduces power consumption, for the processing that solves the homogeneous structure part provides referential experience.

The specific embodiment

Present embodiment part feeder structure is as shown in Figure 1, adopts the semi-rigid cable material, and part material is combined by metal copper pipe 21, nonmetal interlayer 22, metallic copper core 23 3 parts, belongs to the composite and flexible material, and maximum draw ratio can reach 60.The drawing processing request becomes required part feed line after removing metal copper pipe 21.

Present embodiment adopts processing method of the present invention to be:

The first step; The design special screw shell is as shown in Figure 2, and described special screw thread sleeve 3 comprises screw die 31, screw die lock sleeve 32 and tapered sleeve 33; Screw die 31 is cutters of a kind of threading; Wherein the widest with the circular die application, specification limit is that M0.25～M68mm. circular die, six square die countries all have GB, its big or small use that matches with screw die lock sleeve 32.With screw die 31 screw die lock sleeve 32 front ends of packing into, use screw lock during use.Tapered sleeve 33 front end circular holes and screw die lock sleeve 32 rear end optical axises match, and its rear end taper shank angle matches with the tailstock tool tapering.Three assemble is a cover special screw thread sleeve.

Second step, semi-rigid cable part 2 is packed in the lathe spindle folder jar 1, expose the length of required processing;

The 3rd step, tapered sleeve 33 tailstock tool 4 of packing into,, pass tailstock with the screw die 31 of lock sleeve 32 clamping M4 * 0.5, make screw die 31 incision parts, manually cover system screw thread stops to process when being worked into part front end 3～5mm place;

In the 4th step, cut the dark cut of 0.15mm at the circumferential surface of required processing length with cutting knife;

In the 5th step, jog tailstock tool handwheel, part under the effect of tightening force, make the metal copper pipe 21 of cable components 2 break away from nonmetal interlayer fully in the special screw thread quill, accomplish the processing of semi-rigid cable part 2.

In the present embodiment, part 2 suffered clamping forces are main with axial force, have overcome the harmful effect that traditional processing radial force causes workpiece deformation.But self-control anchor clamps repeated multiple times is used when processing with a kind of part, has reduced the consumption of material, has improved efficient.

Combine accompanying drawing that exemplary description has been carried out in use of the present invention above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasions without improving, all within protection scope of the present invention.

The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
