Detailed description of the invention:
With reference to Fig. 1, bench drill Workpiece clamping device, is the relevant equipment on bench drill 1 workbench 11, to be processed for clamping
Workpiece, in order to smoothly complete processing.Clamping device includes base plate 2, cylinder 3, link gear 4, lever 5 and pressing plate
6.Described base plate 2 is fixed on workbench 11 or other fixture of bench drill, is used for fixing cylinder 3 and uses；Cylinder 3 is locked
Gu on this base plate 2 bottom surface, piston rod 31 is upward through base plate 2, this piston rod 31 end is connected to lever 5 rear end,
Activation lever 5 swings up and down；Being provided with fulcrum 7 on workbench 11, more specifically, this fulcrum 7 is a stud, should
Stud passes preformed hole in the middle part of lever 5, and stud is positioned at lever 5 upper and lower to lock respectively has nut 71, wherein above
Nut is configured with a spherical pad 72, and this spherical pad 72 can provide lever 5 to swing surplus.
Being supported by this fulcrum 7 in the middle part of described lever 5, lever 5 front end lock intrinsic energy pushes down the pressing plate 6 of workpiece, by this
Pressing plate 6 by Work-sheet pressing on workbench 11 table top；Cylinder 3 is controlled by link gear 4, this link gear 4 and platform
Creep into and link to handle 12.
And link gear 4 includes electromagnetic valve 41, travel switch 42 and limited block 43；Limited block 43 is arranged on feeding hands
On the calibration loop 13 of handle seat, travel switch 42 is fixed on the main spindle box 14 of bench drill, can touch for limited piece 43；OK
Cheng Kaiguan 42 controls electromagnetic valve 41 break-make, switching pressure-air turnover cylinder 3, it is achieved drive piston rod 31 to stretch out or return
Contracting, drives lever 5 clamp or unclamp workpiece then.Entered the air pressure of cylinder 3 by regulation, clamping force can be realized
Regulation；It addition, during boring stroke difference, the trigger point of travel switch 42 can be changed by adjusting calibration loop 13,
Enable the action of the action effectively match-drill of lever.Process different types of workpiece, replaceable different pressing plate 6.
More specifically, for processing wood pearl equal sphere drilling-workpiece, described pressing plate 6 becomes circular ring, by two
Or three bolt 61 movable hangings are contained on the slotted eye 51 that lever 5 front end is corresponding, pressing plate 6 both sides, two bolt 61 offices,
It is in the front of annulus center of gravity, and is fixed with two ball studs 52 on the annulus lever 5 that radially two quadrantal points are corresponding, this bulb
The ball head 521 of pin can be conflicted and pressing plate 6, is formed pressing plate 6 dynamic pressure；And the 3rd bolt 61 is in pressing plate 6
Rear position, can balance lifting pressing plate 6, can add dynamic pressurized on pressing plate 6 by the ball head of two ball studs 52 again,
It is adaptive to the workpiece of injustice, such as plank.Pressing plate 6 according to different Product processing needs, may be designed to such as triangle,
The structures such as square.
For another example Fig. 1, the air vent of cylinder 3 connects a pipeline 32, and pipeline 32 extends to main spindle box front end, pipeline 32
End connects air jet pipe 33, and the puff prot of this air jet pipe 33 is towards the position of pressing plate 6.Cylinder action can be made full use of
Time interval aerofluxus, blow the chip that the course of processing is formed open, it is not necessary to extra increasing blows bits equipment.
Operation principle is as follows:
(1) part is placed on the appropriate location of workbench 11；
(2) pushing down on feeding handle 12, drive limited block 43 to rotate and touch travel switch 42, now stroke is opened
Closing 42 closings of contact, electromagnetic valve 41 obtains electric, and after solenoid valves, pressure-air enters cylinder 3, the piston rod of cylinder
31 promote pendulum on lever 5 rear end, and lever 5 front end band dynamic pressure plate 6 compresses downwards part to be processed, continues to push down on
Dynamic feeding handle 12 is until part machines；
(3) reversely promoting feeding handle 12, limited block 43 departs from the effect to travel switch 42, and electromagnetic valve 41 breaks
Electricity, pressure-air enters cylinder 3, piston rod 31 pull lever 5 rear end from another interface, and band dynamic pressure plate 6 is up,
Unclamp the part to be processed of compression.
