FIELD OF INVENTION:
(0011 The present invention relates to the field of watch dial. The present
invention in particular relates to a system and method for placing and locking
indexes on watch dial
5 DESCRIPTION OF THE RELATED ART:
[0021 Previous dial index machines of this nature have various drawbacks which it
is a general object of the present invention to overcome. In some cases, the heavy
weight of the moving parts restricts the rapidity with which the workpieces can be
indexed. Often the tools at the work stations must be so mounted as to obstruct
10 access to the stations for maintenance or tooling changes.
[0031 Reference may be made to the following:
[0041 Publication No. GB568013 relates to the rivet, comprises a rivet, preheaded
at, Fig. 6, and drilled to form the bore, together with a core member headed at
before insertion in the bore in which it is a sliding fit. The head, for the pulling
15 grip, is formed after assembly and during the upsetting the fit between the bore
and the part is rendered closer. During heading, the head rests on the bottom of a
bore, Fig. 8, in a die counterbored at to receive the head. The projecting part of the
stem passes through an accurately fitting hole in a die counterbored to receive a
die shaped at to yield the form of head required. A punch slides in the die to effect

the heading. As the die is indexed to the position A. the spring band effects the
reclosing of the die parts, and at this position a fresh blank is inserted either by
hand or by an automatic device.
[0051 Publication No. US3646653 relates to a depression in the die is filled with a
liquid or pasty substance which supports the dial blank. A descending punch
pushes the blank part way into the depression causing the substance of the cushion
to force the blank into the punch hollows corresponding to the symbols to be
raised. The die depression is surrounded by an upstanding rim that penetrates part
way into the blank when the latter is pressed by the punch.
(006) Publication No. US5784932 relates to a rotary indexing table has a table
defining a flat table surface. A dial having an upper surface and a lower surface is
5 positioned over and generally parallel to the table surface. The dial further defines
a circular inner edge and an outer edge. First bearings mounted to the table surface
engage the inner edge of the dial to radially support the dial on the table. Second
bearings axially support the lower surface on the table surface for rotation. The
second bearings comprise circular grooves in the lower surface of the dial and
10 concentric with the inner edge. Ball bearings are in the grooves and in contact
with the flat table surface.
[007) Publication No. US3451291 relates to a manual indexing mechanism for a
dial feed mechanism which is operative to disconnect the dial feed from the press
drive. The mechanism includes timing means which assure the proper timed
•15 relationship when the dial feed is re-connected to the pre;;s drive.
[008) Pub! ication No. US20 12266721 relates to a rotary index table comprising a
plate, which has drivers that engage with a drive groove of a cam barrel, wherein
the plate can be driven by means of the cam barrel to carry out a rotational
movement about a rotational axis which in tum can be driven by means of a motor
20 to carry out a rotational movement about the longitudinal axis thereof, and
wherein the motor directly drives the cam barrel.

[009] Publication No. US3829076 relates to a machine for indexing workpieces to
a succession of work stations. A base supports a lightweight fabricated indexable
work holding ring which supports workpieces outwardly and above the base. The
work stations carried by the base are thus inside the ring, permitting easy
accessibility to the ring. A cam drive mechanism is mounted outwardly of the
base and under the ring. Piping and wiring may extend radially from the base
center.
(010] Publication No. US876574 relates to dividing or index heads for filling and
other machines, the work being fixe the operation controlled by setting said
spindle at different angular positions of rotation and direction, whereby spur or
bevel gears may be out, or work milled at various angles and in various positions.
5 The axis of the shaft 21 is coincident with the axis about which the swivel stock 2-
turns, for convenience when the device is used in connection with power-driven
gears in mesh with the described ears, to 'effect uninterrupted rotation of the
spindle when cutting spiral etc.

10 rollers in a housing with parallel, spaced apart axes of rotation. Each cam roller is
driven by a respective servomotor with an angle sensor, frequency inverter and a
control or regulation device with freely programmable synchronous control or
synchronous regulation of the cam rollers in the latching path via a respective
transmission. An independent claim is also included for a controller for regulating

[012) [n order to overcome above listed prior art, the present invention aims to
provide to a system and method for placing and locking indexes/decorative
components on watch dial
OBJECTS OF THE INVENTION:
[013) The principal object of the present invention is to provide a system and
method for placing and locking indexes/decorative components on watch dial.
[014) Another object of the present invention is to provide easy and effective
method of locking indexes/decorative components on watch dial.
SUMMARY OF THE INVENTION:
[015] The present invention relates to a system and method for placing and
locking indexes/decorative components on watch Jial. There is a mechanical
locking mechanism to lock the index/decorative components on the dial
plate. Index which is decorative part contains two feet on its bottom shown in
figure I and help to locate the position of the index on the dial and also locking of
the index with dial. By locking mechanism feet of these indexes got flared as
shown in figure 4, which basically help to robust the assembly of dial and index.
5 After placing the index on dial shown in figure 2, pressure is applied, which
pushes the locking pins upward and feet gets flare.
(016] As the index/decorative components is made of malleable material, its gets
flared on putting up a little pressure. To flare the index feet, length of the feet
should be at least equal to dial thickness or more than that. And dial is placed on
10 the locking mechanism and force is applied locking pins moves toward index feet
and push on the material of feet which flares the index.
BREIF DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION:
[022] The present invention relates to a system and method for placing and
locking indexes/decorative components on watch dial. There is a mechanical
locking mechanism to lock the index/decorative components on the dial plate.
25 Index which is decorative part contains two feet on its bottom shown in figure 1
and help to locate the position of the index on the dial and also locking of the
index with dial. By locking mechanism feet of these indexes got flared as shown
in figure 4, which basically help to robust the assembly of dial and index. After
placing the index on dial shown in figure 2, pressure is applied, which pushes the
locking pins upward and feet gets flare.
5 [023] As the index/decorative components is made of malleable material, its gets
flared on putting up a little pressure. To flare the index feet, length of the feet
should be at least equal to dial thickness or more than that. And dial is placed on
the locking mechanism and force is applied locking pins moves toward index feet
and push on the material of feet which flares the index.
10 [024] Round steel plates are used to manufacture this mechanism of index
locking. Holes are drilled in top and bottom plate according to hole position of the
index on the dial. Locking pins are in conical shape placed below the top plate of
the tool as shown in figure 3 position exactly behind the index and 4 springs
which helps to maintain the gap between these tools. When pressure is applied
15 against the spring force than locking pins move towards the feet of the index and
flares the index feet.
[025] This mechanism is created as per the requirement of locking of the index
with dial mechanically. This is an easy and effective method of locking
indexes/decorative components on watch dial
20 [026] Numerous modifications and adaptations of the system of the present
invention will be apparent to those skilled in the art, and thus it is intended
by the appended claims to cover all such modifications and adaptations
which fall within the true spirit and scope of this invention.
