Description
Technical field
The present invention relates to a kind of special equipment for tapping, especially directly the workpiece such as nut are entered using straight shank tap
The tapping machine of capable continuously internal thread machining.
Background technology
In the processing of the components of machine such as nut, it is often required to make internal thread (tapping), the tapping machine commonly used at present is nothing but
Two types：First, using straight shank tap, screw tap is arranged in the chuck of main shaft.During work, parts to be processed is clamped first, so
Start motor afterwards and drive chuck rotation, by controlling the axial movement of main shaft, so as to drive spiral shell in screw tap rotation incision, processing
Line, when screw tap reaches predetermined depth, motor is inverted immediately, and also processing part is exited in reversion to screw tap therewith, is completed once single
Journey tapping.2nd, bent shank tap, is typically used on Horizontal tap, and be not required to motor reversal continuously can enter to nut blank
Row screw thread process.During work, the nut blank of hexagonal guide rail (being commonly called as runway) positioning and clamping mechanism is fallen on by hopper, will by push rod
It is pushed on screw tap, and screw tap curved handle part is shifted onto on the top cover of chuck, therefore screw tap while rotate together with chuck, silk
Cone makees feed motion again, and after tap tapping, straight line portion of the nut finished product along tap holder is moved successively, and curved by tap holder
Bent part is fallen into finished product bucket.
Using the tapping machine of straight shank tap, be not required to lengthening handle and welding curved handle, but the frequent rotating of motor have it is fragile
Motor, the shortcoming for wasting the energy, and screw tap rotating repeatedly, exacerbate the abrasion of screw tap, influence the quality and yield of screw thread.Make
With the tapping machine of bent shank tap, screw tap, which is not required to reversion, can complete tapping, be effectively reduced energy consumption, improve electrical machinery life,
Screw tap abrasion is reduced simultaneously, improve yield.However, screw tap improves the cost of work time cost and screw tap when welding curved handle；
After screw tap lengthening handle, rigidity is deteriorated, and the product quality processed declines；On the other hand, when processing part is longer, part can not
By the bent portion of bent shank tap, so as to limit the range of work.In summary, how to provide it is a kind of using straight shank tap,
It is not required to screw tap reversion, accuracy of thread high, energy-conservation, efficient tapping machine urgently to be resolved hurrily.
The content of the invention
It is not required to instead using straight shank tap and screw tap it is an object of the invention to overcome the deficiencies of the prior art and provide one kind
Turn that the automatic tapping machine of tapping can be continuously finished.
The present invention's is realized in：A kind of automatic tapping machine, including frame and bunker mechanism, it is characterised in that：

It is positioned between side and push rod 41, is recycled into next tapping flow.
Operation principle and process：
Fig. 6 to Figure 10 carries out principle explanation to tapping flow of the present invention, for convenience of description by taking single shaft as an example.
In figure 6, the extruding of spring 319 gripping block 318, by the staight shank of its front end floating clamping mechanism, positioning with semi-finished product 316
Screw tap 35；The main shaft 21 for being located at the coaxial direction of straight shank tap 35 is mobile along the axis direction of straight shank tap 35 (upper right side in figure), main
Four square holes 212 that axle 21 is set stretch to straight shank tap afterbody four directions 352, four after being stopped the rotation due to upper tapping flow main shaft 21
The ability of square hole 212 is disengaged from straight shank tap afterbody four directions 352, therefore the square hole 212 of main shaft four and cubic 352 positions of straight shank tap afterbody
Fit like a glove.
In the figure 7, after the square hole 212 of main shaft four is automatically performed combination with straight shank tap afterbody four directions 352, main shaft 21 stops
It is mobile；Push rod 41 promotes the blank 11 for completing positioning to push up to straight shank tap head along the axis direction of straight shank tap 35 (lower left in figure)
Portion 351, when shifting the rear end of gripping block 318 (as shown in Figure 8) onto, the extruding gripping block 318 of spring 319 clamps blank 11.
In fig. 8, main shaft 41 starts to rotate while driving straight shank tap 35 to rotate, and tapping processing starts；By gripping block 318
Clamping semi-finished product 316 carry out tapping processing along the axis direction of straight shank tap 35, push rod 41 continues according to the pitch size of blank 11
Synchronizing moving, promotion carries out tapping processing by the blank 11 of floating clamping mechanism.
As shown in figure 9, push rod 41 promotes blank 11 to be machined to stop during 316 position of semi-finished product, while main shaft 21 stops rotation
Turn, now the semi-finished product 316 of upper tapping flow are processed as finished product 36.
In Fig. 10, stop during 21 rollback initial position of main shaft, the front end of four square hole 212 and straight shank tap afterbody four directions 352
Between form certain space because the axis of straight shank tap 35 is with the horizontal certain angle, thus finished product 36 by gravity from staight shank
Screw tap afterbody four directions 352 is slipped in above-mentioned space, when angle is small or the lightweight dependence gravity deficiency of blank can also be set with sliding
Put device (such as cylinder) and help blanking, its thinking is also within the scope of the present invention；In addition, when main shaft 21 retracts, push rod 41 is simultaneously
Retract, stop to initial position along the axis direction of straight shank tap 35 (upper right side in figure), new blank 11 falls into straight shank tap head
It is positioned between the front of portion 351 and push rod 41.It is recycled to Fig. 6 and forms continuous self-tapping.
The tapping machine pusher 4 of the present invention, axis feeding mechanism 2, as feeding power, can also be made using servomotor
With power sources such as stepper motor, pneumatic and hydraulic pressure, its thinking is included in the scope of the present invention.
