Detailed description of the invention
The present invention includes that board 1, described board 1 top are provided with the knife rest 2 being correspondingly arranged with board 1；
Described knife rest 2 is provided with drill bit 3, is provided with and is in drill bit 3 top and the unit head 21 of drill bit 3 connection, be provided with outer limited block 22 and the inner limited block 23 of spacing unit head 21 position in described knife rest 2 in described knife rest 2；
Described board 1 is provided with the slide rail 4 that can move along board 1 dual-side 11, and described slide rail 4 is provided with the fixture 5 that connect fixing with slide rail 4, and described fixture 5 is clamped with workpiece 6；
Described board 1 both sides are provided with close to device 7, described are used for positioning described slide rail 4 front and back position close to device 7；
Described board 1 is made up of the fixed side of two contacted with described slide rail 4 11 and middle middle platform 12, described middle 12 by the fixed outer middle platform 121 for supporting described fixture 5 and in can moving up and down in platform 122 form, described interior middle 122 upper surfaces and described fixture 5 lower surface are provided with the magnetic face repelled each other；
Being provided with the cavity of accommodating described fixture 5 in described slide rail 4, described cavity both sides are provided with the supporting rod 51 clamping described fixture 5, and described supporting rod 51 is telescopic and fixture 5 realizes being contacting and separating；
Described fixture 5 top is provided with the drill bit 3 for boring.
Described be provided with, close proximity to platform 122 upper surface in device 7 and fixture 5 lower surface, the magnetic face repelled each other, in middle part in the upper surface of platform 122 be non-magnetic surface.
Described identical with the area of described fixture 5 lower surface close proximity to platform 122 upper surface area middle in device 7.
Described unit head 21 is arranged on the slide block of left and right displacement line slideway 24, realizes displacement by cylinder；Unit head 21 is driven ball screw 27 to realize bottom and top feed by feeding line slideway 25 by motor 26 and moves.
During work, left and right displacement cylinder 28 is in the state of inside contracting, and two drilling power heads 21 are close to outer limited block 22, and centre-to-centre spacing is big value.Moving forward and backward cylinder 8 and be in the state of inside contracting, after installing workpiece 6, two drilling power heads 21 are driven by spindle motor and rotate, and motor 26 drives, and carries out bottom and top feed motion, starts to bore holes.After boring terminates, drilling power head 21 moves, then, left and right displacement cylinder 28 and move forward and backward cylinder 8 and promote simultaneously, two drilling power heads 21 are close to inner side limiting-position block, and centre-to-centre spacing is little value, when frock clamp 5 is close to close to device 7, then starts second time and hole, after boring terminates, move on drilling power head 21, left and right displacement cylinder 28 and move forward and backward cylinder 8 and be in the state of inside contracting, restPoses, prepares next work pieces process, the whole course of processing is by PLC control, it is achieved automatically process.Spindle motor belt wheel is by tensioning spring 9 tensioning, it is ensured that all in tensioning state during drilling power head 21 left and right displacement.
The two of the present invention are previously set close to the position of device 7 so that when slide rail 4 touch both sides close to device 7 time, workpiece 6 location, just at the lower section of both sides drill bit 3, is realized the boring work to workpiece 6 by drill bit 3.
The present invention close to device 7 can be the mechanical structure form such as limited block, it would however also be possible to employ the electronic devices such as sensor.
nullThe present invention is in slide rail 4 motor process，Slide rail 4 produces with the side 11 of board 1 and contacts，Therefore when slide rail 4 does not arrives predeterminated position，Slide rail 4 and fixture 5 all will not produce any contact with middle 12，Thereby ensure that fixture 5 will not produce abrasion because contacting friction with middle 12，When slide rail 4 arrives precalculated position，Now the supporting rod 51 of clamping fixture 5 is retracted under control of the control means，Therefore fixture 5 can be acted on by gravity and interior middle 122 magnetive attractions，Gravity and the magnetive attraction repelled each other being subject to that can be subject to by the place holder 5 preset when making supporting rod 51 regain in advance can be roughly equal，So can generally remain the balance and stability of fixture 5，In in now controlling, platform 122 moves downward，In in so, platform 122 and fixture 5 are that distance increases，Corresponding mutual expelling force diminishes，Therefore fixture 5 the most also moves downward，Until keeping balance，According to above-mentioned principle until fixture 5 contacts with outer middle 121 generation，Now due to the support of outer middle 121，Even if interior middle platform 122 moves downward，Now fixture 5 also will not downwards or move upward，When fixture 5 is in this position，By relevant positioner, fixture 5 can be positioned，Then hole，Owing to relevant positioner is too many、Structure is the most varied，The present invention only need to reach positioning function，Therefore the most do not launch positioner at this to describe.
The present invention further can arrange the guide rail of correspondence in described slide rail 4 side, and this guide rail should not contact overstocked with fixture 5 certainly, only serves certain guide effect.
The present invention is after a boring, moving up interior middle 122, now fixture 5 moves upward under the effect of mutual expelling force, until fixture 5 moves up to contact with supporting rod 51 and by supporting rod 51 clamping position, then workpiece 6 is moved to opposite side position, complete another hole machined.
The driving structure that additionally present invention drives slide rail 4 to move does not limits, as long as can realize moving, does not the most launch to describe.
The motion of each parts of the present invention can use the intelligent control methods such as PLC to be controlled.
