Background technology
At present, during with the threaded workpiece of numerical control Vehicle Processing, generally adopt special-purpose threading tool and undertaken by programme-control.Add man-hour, the radial load that workpiece bore is bigger.When less and reach was longer as the screw thread nominal diameter of processing work, threading tool made its flexural deformation easily to the radial load of workpiece, thereby its workpiece is scrapped.So with the whorl work piece that the numerical control car is processed, general nominal diameter is big and length is not long.
Simultaneously, existing numerical control car can not have the workpiece of diameter larger axis shoulder with threading tool machining screw latter end.Because, during the screw thread process finishing, the lathe tool shaft shoulder end face of damaging easily, thus workpiece is scrapped.
Meet threaded workpiece of numerical control Vehicle Processing and screw thread nominal diameter less, when length is longer, usually take the thread generator structure of engine lathe is placed on the tailstock of numerically controlled lathe, hand tailstock comes machining screw.Perhaps unload workpiece, method tapping by hand, or forward other machine tooling to.Action need frequent starting lathe like this, frequent clamping workpiece is also wanted the centering workpiece, and whole work-piece can not be finished the operation of processing of requiring to greatest extent in a clamping, and working (machining) efficiency is low.Hand tailstock is the method for engine lathe machining screw, and it is to come transferring power by the outer ancient piece of jade, round, flat and with a hole in its centre of thread generator structure clamping part and the friction of tailstock endoporus, and the two contact portion is skidded easily, thereby screw thread is scrapped.Simultaneously, hand firmly uneven in process, also make the form of thread inequality easily, thereby cause workpiece to be scrapped.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of and can process the screw thread that diameter is less, length is long continuously with Digit Control Machine Tool, or the screw thread latter end has the workpiece than the major diameter shaft shoulder, a kind of numerically controlled lathe screwing tool that process non-cutting time to reduce, improves working (machining) efficiency, it is achieved through the following technical solutions:
Comprise threading tool, body of tool and sleeve, body of tool is socketed in the sleeve outside, and both can move to axial, and the threading tool clamping is at the front end of sleeve.
All sides of described sleeve are axially arranged with gathering sill along it, and a screw radially is screwed on the body of tool and passes body of tool and extends in the described gathering sill, and body of tool is moved axially along the relative sleeve of gathering sill.
The utility model makes numerically controlled lathe finish the processing of screw thread on a plurality of thin and long units continuously in a clamping by adopting a screwing tool, whole process is finished automatically, dress cutter number of times significantly reduces, save non-cutting time, enlarged the range of work of numerically controlled lathe, improved the lathe in machining slender piece or had larger axis to take on the screw processing quality of workpiece.Improve operating efficiency, effectively cut down finished cost, alleviated operator's labour intensity.By control program entire mechanism and cutterhead are moved axially with the speed that is slightly smaller than one times of pitch T, like this, when screw die or screw tap machining screw, can slowly cut workpiece, produce when preventing behind the cutter contact workpiece before the processing several pitch and skid, thereby cutter is squeezed and damages, improve the utilization rate of cutter.Behind threading tool incision workpiece; cutter drive sleeve moves with the speed of one times of pitch; and body of tool and cutterhead move in the same way with the speed less than one times of pitch; the two produces differential moving; body of tool is unlikely to compression sleeve and causes the form of thread distortion in the process; screw die or screw tap can not damaged because of being squeezed, can effectively protect screwing tool, increase operation rate.
Gathering sill on this instrument middle sleeve also is convenient to chip removal and cooling fluid and is discharged except that playing guide effect, has protected cutterhead better.
Description of drawings
Fig. 1 is the structural representation of the screwing tool of the utility model one embodiment.
Fig. 2 be shown in the structural representation of screwing tool clamping threading on numerically controlled lathe.
Fig. 3 be shown in the structural representation of screwing tool clamping machining internal thread on numerically controlled lathe.
Among the figure, 1 holding screw, 2 screw die, 3 guider screws, 4 body of tool, 5 sleeves, 6 gathering sills, 7 workpiece, 8 cutterheads, 9 tap chucks, 10 screw taps.
The specific embodiment
Contrast Fig. 1, the screwing tool of present embodiment mainly is made up of screw die 2, body of tool 4 and sleeve 5.Body of tool 4 is socketed in the outside of sleeve 5, and both can move to axial, and screw die 2 is by the front end of holding screw 1 clamping at sleeve 5.All sides at sleeve 5 are axially arranged with gathering sill 6 along it, in all sides of body of tool along its guider screw 3 that radially spins, this screw extends in the gathering sill 6 on the sleeve, makes body of tool 4 move axially and can not do relative rotating relative to sleeve along gathering sill 6 by the screw 3 that spins on it.
Contrast Fig. 2 in the horizontal cutter spacing hole of numerically controlled lathe cutterhead 8, is pressed on screwing tool clamping shown in Figure 1 on the cutterhead 8 by the cutterhead housing screw, notes during clamping with the gathering sill on the body of tool 4 down, so that chip removal and cooling fluid are discharged.After tool setting, body of tool is adjacent to sleeve naturally.By design, make the axial feeding L of cutterhead 8 be slightly less than the pitch T of screw thread on the part to be processed to the lathe working procedure.
After the screw thread processing beginning, when threading tool contacts with workpiece end face, because the screw die entry has tapering, the tapering that workpiece screw thread incision end also has chamfering to form, the two former circle when incision will experience a break-in incision stage (forming the incomplete thread part on the workpiece this moment).If this moment, cutterhead drove the feeding speed feeding of screwing tool with one times of pitch, often form following situation: the screw die 2 on the screwing tool advances along the screw thread machine direction, during beginning, screw die can not be cut on the workpiece because cutting force is not enough, and screw die is subjected to big extruding force easily and damages at this moment.So, in working procedure design, make the axial feeding L of cutterhead 8 be slightly less than the pitch T of screw thread on the part to be processed.Like this, make the screw die can be with the incision of speed more slowly workpiece 7, screw die be vulnerable to big extruding force and damages, thereby protects screw die effectively.
Behind screw die 2 incision workpiece 7, screw die and sleeve are by the speed motion of 1 pitch T/ circle, the speed motion of 4 of the body of tool of clamping on the cutterhead 8 designed 88~98%T/ circle that is slightly less than pitch T in by working procedure, the translational speed of sleeve and screw die is faster than the speed of body of tool and cutterhead, because being subjected to the restriction of guider screw 3, sleeve can not produce circumferential rotation, can only move axially faster than cutterhead, body of tool 4 produces differential between the two with sleeve 5, the sleeve of being close to body of tool 4 separates with body of tool gradually, gathering sill on the sleeve constantly exposes, and cooling fluid and tiny smear metal just fall from gathering sill.
The contrast Fig. 3, screwing tool of the present utility model is equally applicable to machining internal thread, at first by holding screw 1 with screw tap 10 fixedly clamping on tap chuck 9, with screw tap chuck 9 is fixed on the front end of sleeve 5 again.Process is similar to the above process, repeats no more.
