FIELD OF THE INVENTION
The present invention is related to mechanical apparatus for opening or tightening of
slotted ring-nut of different diameter in assembly of test piece.
BACKGROUND OF THE INVENTION
The slotted ring-nut arrangement for assembly of different mechanical parts in the
test piece is one of the best technique of stable & play-less assembly. But for
opening or tightening of slotted ring-nut from assembled structure of test piece,
operator has to use different diameter of driver for different size of slotted ring-nut.
There is no generic driver which can be use for different size of slotted ring-nut for
any test piece. In a complete assembly of one test piece there is various size of
slotted ring-nut and it become very cumbersome to operator for selection of different
driver for various size of said ring. There is chance of manual mistake for selection of
proper driver for particular size of slotted ring-nut which causes damage of slot
corners during opening or tightening operation and at the same time it increase
production cycle time for selection of proper driver. The Adjustable Driver for Slotted
Ring-nut is kind of tool for opening & tightening of different size of said ring. This
generic apparatus can be use for assembly of any type of test piece.
SUMMARY OF PRESENT INVENTION
. The Adjustable Driver for Slotted Ring-nut is generic apparatus to use in said ring
assembly operation for any type of test piece. The process of selection of specific
Annexure‐II
driver for one type of slotted ring-nut is avoided by adjustment of driving length of
said apparatus.
New adopted process for tightening or opening of slotted ring-nut by said apparatus
is useful in accordance of following aspect-
In accordance with one aspect of present invention, the said apparatus
provides uniform tightening & opening of slotted ring-nut in assembly of test piece.
In accordance with second aspect of present invention, the said apparatus
can be use to hold different diameter & size of slotted ring-nut in assembly of test
piece.
In accordance with yet second aspect of present invention, the said apparatus
result tightening of slotted ring on the thread of other mailing part without overlapping
& filling of neighboring turns of thread.
In accordance with yet another aspect of present invention, it is smaller in size
& weight and handy to transport at different work station.
In accordance with yet another aspect of present invention structure is such
that it holds the assembly test piece preciously & stable which cause errorless
tightening & opening operation.
In accordance with yet another aspect of present invention, the assembly by
said apparatus is fully manual, so operator can adjust the applied force during
tightening & opening operation as per assembly requirement of the test piece.
In accordance with yet another aspect of present invention, the said
apparatus has flexibility to change its driving length by adjustment of any of the plate
(left or right).
In accordance with yet another aspect of present invention , the said
apparatus design structure provide capability for tightening or opening of slotted ringAnnexure‐
II
nut inside the cylinder type assembly , this feature make it very effective for precision
optical collimator type assembly of test piece.
In accordance with yet another aspect of present invention, the tip ( griping
width) of the left & right plate of said apparatus is harden which increase the life of
said apparatus.
In accordance with yet another aspect of present invention the two dowel pin
provide guided sliding of both plate ( left & right) on each other which stabilized fixing
of both plate at required dimension.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is an Assembled structure Adjustable Driver for Slotted Ring-nut.
Fig. 2 is a detail mechanical design of left & right plate.
DETAILED DESCRIPTION
Referring the figure 1 and 2, the Adjustable Driver for Slotted Ring-nut is a
tightening & opening tool for slotted ring-nut in assembly of test piece. The said
apparatus is assembly of 06 different item, they are called as pos.1- right plate,
pos 2- left plate, pos 3-Standard dowel, pos 4-standard Allen Screw, pos 5- standard
washer and pos 6 – standard nut.
The right plate 1 has special design shape, L-shape of plate which is taper in
width toward griping head and on upper side its has rectangular shape. At upper side
of right plate 1, there is slot for assembly of left plate 2 with Allen Screw 4, washer 5
& nut 6. The left plate 2 is mirror image of right plate 1 and its slot overlap with slot of
Annexure‐II
right plate1. The length & width of both plates, kept in such a way that it provide
proper griping of said apparatus during tightening & opening operation of slotted
ring-nut. The taper shape leg of both plate 1 & 2 make it capable to go inside the
cylinder type assembly and at the same time taper shape provide sufficient strength
to the structure. For guided sliding of right plate 1 & left plate 2 , there is two dowel
pin mounted on left plate 2, this provide stabilized fixing of both plate at required
dimension.
