Detailed description of the invention
As depicted in figs. 1 and 2, the manual punching hole method that the present embodiment provides, the puncher that this drilling method adopts comprises the bed die 2 be arranged on work top 1, be vertically arranged on locating dowel 3 on work top 1, be set in locating dowel 3 and be positioned at locating module 4 above bed die 2, parallel with locating dowel 3 and being arranged on mandrel 5 on locating module 4, being arranged on the vent needle 6 of mandrel 5 bottom and the governor motion 7 for regulating mandrel 5 to move up and down along its length direction.
In this example, above-mentioned bed die 2 has the locating slot 20 placing parts to be processed, and vent needle 6 is positioned at directly over locating slot 20, and is provided with the hole 200 coordinated with vent needle 6 at the bottom land of locating slot 20.
Simultaneously, be provided with tooth bar 50 in the side of mandrel 5 relative positioning post 3, governor motion 7 comprises and being arranged in locating module 4 and the gear 70 matched with tooth bar 50, the gear shaft 75 being arranged on gear 70 center and through the end of gear shaft 75 and the driving handle 71 rotated for driven wheel 70.Adopt driving handle 71 driven wheel 70 to rotate, thus be with moving mandrel 5 to move up and down along the bearing of trend of tooth bar 70.
Above-mentioned locating module 4 can regulate along locating dowel 3 length direction and arrange, and locating module 4 can also rotate around locating dowel 3.Thus according to the size of workpiece, up-down adjustment locating module 4, or rotate around locating dowel 3 and regulate, make vent needle 6 position adjustable, namely can meet the processing of different workpieces.
In addition, above-mentioned governor motion 7 also comprises the upper end stroke lever 73 that stroke dog 72, end that is arranged on mandrel 5 top is fixed on locating module 4 and the extension spring 74 be arranged between stroke lever 73 the other end and stroke dog 72.Wherein stroke lever 73 comprises the erection part 730 extended along mandrel 5 length direction, the heel 731 bending directly over stroke dog 72 from the end of erection part 730, stroke dog 72 is provided with connecting portion 720, extension spring 74 both ends are connected to heel 731 and connecting portion 720, by the active force of extension spring 74, be convenient to moving up of mandrel 5, guarantee the stability that mandrel 5 moves up and down.
The specific works of the governor motion 7 of the present embodiment is as follows:
Workpiece to be processed is placed in locating slot 20, press driving handle 71, gear shaft 75 is rotated and the rotation of driven gear 70, and then mandrel 5 is moved down along the bearing of trend of tooth bar 50, moving down of mandrel 5, simultaneously, moved down by the stroke dog 72 being arranged on mandrel 5 top, extension spring 74 is made to be in extended state, now, vent needle 6 is through the hole 200 being positioned at locating slot 20 on bed die 2, realize the punching of workpiece to be processed, then, loosen driving handle 71, gear 70 is turned round, tooth bar 50 is driven to move up, simultaneously, under the recovery deformation effect of extension spring 74, also mandrel 5 is pulled to move up, thus vent needle 6 is risen, depart from locating slot 20, take out in self-align for the workpiece after processing groove 20, complete the time processing of workpiece.
In sum, drilling method of the present invention, controls mandrel by governor motion and moves up and down along its length direction, vent needle is passed be positioned at the hole of locating slot on bed die, realize the punching of workpiece, locating module can regulate along the length direction of backstay and can regulate around the rotation of backstay simultaneously, meets the punching demand that certain is specialities diverse location, in addition, the puncher that the present invention adopts, structure is simple, and it is convenient to implement, and cost is lower.
Above to invention has been detailed description; its object is to allow the personage being familiar with this art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; the equivalence change that all Spirit Essences according to the present invention are done or modification, all should be encompassed in protection scope of the present invention.
