Description
Technical field
The invention belongs to machining technology field, is related to a kind of Simple clamp, and in particular to one kind is used for Drilling operation
Self-centering type clamping device.
Background technology
The plate-likes such as flange, end cap or annular work piece are common parts in machining industry, traditional such drilling of processing
Method is that crossed process is had to pass through before drilling, because annular work piece has centre bore, bad alignment point, therefore router
Make considerably complicated, labor intensity has been significantly greatly increased, has reduced production efficiency and machining accuracy can not be effectively ensured.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art, there is provided a kind of boring clamping of self-centering type
Device, its can self-centering, bore position precision is high, and swelling great efforts, process does not produce skew, reasonable in design, structure
Simply, easy to operate, compact is in light weight, convenient disassembly, service life length, is easy to promote the use of.
To achieve the above object, the technical solution adopted by the present invention is：A kind of boring clamping device of self-centering type, bag
The chassis playing fixed supporting role and multiple drill bushings for guiding drill bit to process drilling on annular workpieces to be processed are included, it is special
Sign is：The drill jig of boss is also provided with including the dish type expansion set for holding out against annular workpieces to be processed from the inside and lower surface
Plate；The bushing plate is provided with the upside of the chassis, multiple drill bushings, the bushing plate are fixedly installed on the bushing plate
Middle part is provided with screw rod, and the screw rod upper end is provided with drive nut, and the screw rod lower end is set with the dish type expansion set, described
Dish type expansion set is internally provided with the taper angle being engaged with the boss, is uniformly set along its circumferencial direction on the upside of the dish type expansion set
It is equipped with least two expansion slots.
The present invention has advantages below compared with prior art：
(1) the boring clamping device of the self-centering type when clamping annular workpieces can self-centering, bore position precision
It is high.
(2) the boring clamping device of the self-centering type extends out swelling annular workpieces to be processed using dish type expansion set, thus
Its swelling great efforts, process do not produce skew.
(3) the boring clamping device of the self-centering type is reasonable in design, simple in construction, and operating personnel only need to be by annular workpieces
Installed in the relevant position of the fixture, the clamp operation that annular workpieces can be achieved in drive nut is tightened, use is very easy.
(4) the boring clamping device compact of the self-centering type, in light weight, convenient disassembly, is easy to carry and safeguards.
(5) rigid shock is not present in the boring clamping device of the self-centering type in use, thus it uses the longevity
Life length, is easy to promote the use of.
Below by drawings and examples, the present invention is described in further detail.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the front view of dish type expansion set of the present invention.
Embodiment
The boring clamping device of a kind of self-centering type as Figure 1-Figure 2, including the chassis 1 playing fixed supporting role
It is used to guide drill bit to process the drill bushing 2 of drilling on annular workpieces 7 to be processed with multiple, in addition to holds out against from the inside to be added
The dish type expansion set 3 of work annular workpieces 7 and lower surface are provided with boss 4-1 bushing plate 4；The upside of chassis 1 is set
Bushing plate 4 is stated, multiple drill bushings 2 are fixedly installed on the bushing plate 4, the middle part of bushing plate 4 is provided with screw rod 5, institute
State the upper end of screw rod 5 and be provided with drive nut 6, the lower end of screw rod 5 is set with the dish type expansion set 3, inside the dish type expansion set 3
The taper angle being engaged with the boss 4-1 is provided with, the upside of dish type expansion set 3 is evenly arranged with least along its circumferencial direction
Two expansion slot 3-1, preferably four.
In the present embodiment, the boss 4-1 side walls are provided with transition arc, and transition arc can facilitate dish type expansion set 3 to be open
End is slipped into.
The course of work of the boring clamping device of self-centering type of the present invention is：First by the boring folder of the self-centering type
Tight device is fixed on operating position, turns drive nut 6 clockwise using spanner, screw rod 5 can drive dish type expansion set 3 to transport upwards
Dynamic, the interaction of the endoporus conical surface and boss 4-1 of dish type expansion set 3, dish type expansion set 3 can be expanded outwardly equably, so as to swollen
The endoporus of tight annular workpieces 7 to be processed.Annular workpieces 7 to be processed start drilling machine by after swelling, and drill bit is passed through bushing plate
Drill bushing 2 on 4 can carry out Drilling operation.
It is described above, only it is presently preferred embodiments of the present invention, not the present invention is imposed any restrictions, it is every according to the present invention
Any simple modification, change and the equivalent structure transformation that technical spirit is made to above example, still fall within skill of the present invention
In the protection domain of art scheme.
