Embodiment
The present invention includes board 1, the knife rest 2 that the top of board 1 is provided with and board 1 is correspondingly arranged；
The knife rest 2 is provided with drill bit 3, and the unit head connected in the top of drill bit 3 and drill bit 3 is provided with the knife rest 2
21, the interior outer limited block 22 and inner limited block 23 for being provided with the spacing position of unit head 21 of the knife rest 2；
The board 1 is provided with the slide rail 4 that can be moved along 1 liang of side 11 of board, and the slide rail 4 is provided with and slide rail 4 is solid
Surely the fixture 5 connected, workpiece 6 is clamped with the fixture 5；
The both sides of board 1 are provided with close to device 7, described to be used to position the front and back position of slide rail 4 close to device 7；
The board 1 is made up of the two fixed sides 11 contacted with the slide rail 4 and middle middle platform 12, described
It is used to support the outer middle platform 121 of the fixture 5 and middle platform 122 forms in can moving up and down, institute by fixed for middle 12
State interior middle 122 upper surfaces and the lower surface of the fixture 5 and be provided with the magnetic face repelled each other；
The cavity for housing the fixture 5 is provided with the slide rail 4, the cavity both sides are provided with the folder for clamping the fixture 5
Bar 51 is held, the supporting rod 51 is telescopic and fixture 5 is realized and is contacting and separating；
The top of fixture 5 is provided with the drill bit 3 for drilling.
It is described that the magnetic face repelled each other, middle part are provided with close proximity to the middle upper surface of platform 122 in device 7 and the lower surface of fixture 5
The upper surface of interior middle platform 122 is non-magnetic surface.
It is described identical with the area of the lower surface of fixture 5 close proximity to the middle upper surface area of platform 122 in device 7.
The unit head 21 is arranged on the sliding block of left and right displacement line slideway 24, and displacement is realized by cylinder；Unit head
21 drive ball screw 27 to realize that bottom and top feed moves by feeding line slideway 25 by stepper motor 26.
During work, left and right displacement cylinder 28 is in and inside contracts state, and two drilling power heads 21 are close to outer limited block 22, centre-to-centre spacing
For big value.Move forward and backward cylinder 8 and be in the state that inside contracts, after installing workpiece 6, two drilling power heads 21 are driven by spindle motor to be revolved
Turn, stepper motor 26 drives, and carries out bottom and top feed motion, starts to bore holes.After drilling terminates, drilling power head 21 moves up, so
Afterwards, left and right displacement cylinder 28 and move forward and backward cylinder 8 while promote, two drilling power heads 21 are close to inner side limiting-position block, centre-to-centre spacing
For small value, when frock clamp 5 is close to close to device 7, then start second of drilling, after drilling terminates, on drilling power head 21
Move, left and right displacement cylinder 28 and move forward and backward cylinder 8 be in inside contract state, restPose, prepare next work pieces process, it is whole
Individual process is controlled by PLC, realizes automatic processing.Spindle motor belt wheel is tensioned by tensioning spring 9, it is ensured that drilling power head 21
All in tensioning state during left and right displacement.
The present invention's two is previously set close to the position of device 7 so that when slide rail 4 touch both sides close to device 7
When, the location of workpiece 6 realizes the boring work to workpiece 6 just at the lower section of both sides drill bit 3 by drill bit 3.
The present invention can be the mechanical structure forms such as limited block close to device 7, can also use the electronics devices such as sensor
Part.
For the present invention in the motion process of slide rail 4, the side 11 of slide rail 4 and board 1 produces contact, therefore in slide rail 4 not
When reaching predeterminated position, slide rail 4 and fixture 5 will not produce any contact with middle 12, therefore ensure that fixture 5 and middle 12
Abrasion will not be produced because of contact friction, when slide rail 4 reaches precalculated position, now the supporting rod 51 of clamping fixture 5 is controlling
Retracted under the control of device, therefore fixture 5 can be acted on by gravity and interior middle 122 magnetive attractions, can be made in advance by default
The gravity being subject to of place holder 5 and the magnetive attraction to repel each other that is subject to when supporting rod 51 is withdrawn can be roughly equal, so can be big
The balance and stability of holding jig 5 is caused, now middle platform 122 moves downward in control, and so interior middle platform 122 and fixture 5 are that distance increases
Greatly, corresponding mutual expelling force diminishes, therefore fixture 5 also moves downward under gravity, until balance is kept, according to above-mentioned original
Reason produces contact up to fixture 5 and outer middle 121, now due to the support of outer middle 121, even if interior middle platform 122 moves downward,
Now fixture 5 will not also move downwards or upwards, when fixture 5 is in this position, be able to will be pressed from both sides by the positioner of correlation
The positioning of tool 5, is then drilled, and because the positioner of correlation is too many, structure is also varied, the present invention only need to reach positioning
Function, therefore positioner is not just deployed to describe at this.
The present invention should not can further connect in guide rail corresponding to the setting of the side of slide rail 4, this certain guide rail with fixture 5
It is tactile overstocked, only serve certain guide effect.
The present invention moves up interior middle 122 after a drilling, and now fixture 5 is upward in the presence of mutual expelling force
Motion, until fixture 5 moves up to and contacts with supporting rod 51 and by the clamping position of supporting rod 51, be then moved to workpiece 6
Another side position, complete another hole machined.
The driving structure that present invention driving slide rail 4 moves in addition does not also limit, if motion can be realized, therefore also not
Expansion description.
The motion of each part of the present invention can use the intelligent control methods such as PLC to be controlled.
