Description
Technical field
The utility model belongs to field of machining, is related to a kind of drilling tool.
Background technology
A kind of existing drilling scheme, is clamped by clamp, product is fixed on a base, is placed on CNC milling machine
Complete boring work.Weak point：One is that positioning is inaccurate.Product is also easy to produce play, and the positional precision in hole is completely by numerical control machine
Bed control, is not ensured.Two it is product clamping, unloads and take inconvenience.Three be no drill sleeve device, lacks the guiding work to drill
With；And it is unexpected drill bit may to be made to fracture etc..Four be that boring work is carried out on miniaturized numerical control milling machine tool, and cost is higher, unsuitable
Batch production.
The content of the invention
Goal of the invention：Positioning that the utility model overcomes existing boring method is inaccurate, inconvenience handling, drill bit is without leading
To shortcoming and defect such as, job costs height, there is provided a kind of simple to operate, registration, the low practical machine of processing cost
Bed fixture.
Technical scheme：A kind of boring grab, it is characterised in that the clamp body by lower bushing plate 1, upper bushing plate 2, clamp 3,
Drill bushing C4, drill bushing A5, drill bushing B6, drill bushing D7, alignment pin 8, clamp nut 9, studs 10, support nail 11, closing pin 12, pressure
Tight screw 13 is constituted.Two drill bushing A5, two drill bushing B6 are connected with the upper interference of bushing plate 2, two alignment pins 8, clamp 3, four drill bushings
C4, two drill bushing D7 are connected with the lower interference of bushing plate 1, and housing screw 13 is connected with the upper flank threads of bushing plate 2, upper bushing plate 2
By two closing pins 12 and the lower matched moulds of bushing plate 1, clamp 3 is fixed on lower brill by clamp nut 9, studs 10, support nail 11
In template 1.
Upper bushing plate 2 is in several fonts, and triangle escape groove is provided with product flange side, coordinates to produce with lower bushing plate 1
Product are fastened；To prevent the interference that drill bit and drill bushing occur when drilling two close holes, on two drill bushing A5 being provided with circular arc keeps away
Allow groove, similarly, two drill bushing D7 on lower bushing plate 1 are also provided with circular arc escape groove；The housing screw 13 of upper bushing plate side
By clamping product in the way of screw thread is tightened.
Beneficial effect
Compared with the scheme drilled without fixture, the utility model has the advantages that：One is that mechanism is compact, weight 4.4kg,
It is relatively light, take flexibly.Two be to realize to be accurately positioned product.If housing screw, accurate positioning.Complete mechanical is positioned, and is had
Effect prevents workman from putting product partially in opertions engineering, and the positional precision of holes of products meets product drilling by boring grab guarantee
It is required that.Three be that loading/unloading products are convenient, simple to operate.Product is wrapped in inside frock, can effectively prevent product by grinding, draw
Infringement.Four be above and below bushing plate have drill bushing, there is guide effect to drill bit, cutter head is protected, drilling is accurate；For porous, hole
Away from less product, upper and lower surface drilling avoids drill bit and the interference of drill bushing is more convenient and practical.Five be this fixture bench drill
Or hand drill is carried out, and effectively reduces processing cost, suitable batch production.

Fig. 5 is lower bushing plate axonometric drawing.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：A kind of boring grab,
It is characterized in that the clamp body is by lower bushing plate 1, upper bushing plate 2, clamp 3, drill bushing C4, drill bushing A5, drill bushing B6, drill bushing D7, fixed
Position pin 8, clamp nut 9, studs 10, support nail 11, closing pin 12, housing screw 13 are constituted.Two drill bushing A5, two drill bushings
B6 is connected with the upper interference of bushing plate 2, and two alignment pins 8, clamp 3, four drill bushing C4, two drill bushing D7 connect with the lower interference of bushing plate 1
Connect, housing screw 13 is connected with the upper flank threads of bushing plate 2, upper bushing plate 2 by two closing pins 12 and the lower matched moulds of bushing plate 1,
Clamp 3 is fixed on lower bushing plate 1 by clamp nut 9, studs 10, support nail 11.
Upper bushing plate 2 is in several fonts, and triangle escape groove is provided with product flange side, coordinates to produce with lower bushing plate 1
Product are fastened；To prevent the interference that drill bit and drill bushing occur when drilling two close holes, on two drill bushing A5 being provided with circular arc keeps away
Allow groove, similarly, two drill bushing D7 on lower bushing plate 1 are also provided with circular arc escape groove；The housing screw 13 of upper bushing plate side
By clamping product in the way of screw thread is tightened.
Boring work process is as follows：Product orientation face is fitted with the lower locating surface of bushing plate 1, the long hypotenuse of no flange is close to
Two alignment pins 8, upper bushing plate 2 is by two closing pins 12 and the lower matched moulds of bushing plate 1, and rotating two clamps 3 makes bushing plate 2, tightens
Housing screw 13, realizes the positioning to product.When boring four holes above product, fixture front is placed on the table, and drill bit leads to
Cross drill bushing A5, drill bushing B6 and be oriented to realization drilling；When boring six holes below product, turnover fixture makes its reverse side be placed on workbench
On, drill bit is oriented to by drill bushing C4, drill bushing D7 and realizes drilling.After the completion of drilling, front placing clamp unscrews two clamp nuts 9
With housing screw 13, bushing plate 2 is lifted, product is removed.
