TITLE OF THE INVENTION:
Spring loaded pad locating clamping structure
APPLICANTS:
Crompton Greaves Limited, CG House, Dr Annie Besant Road, Worli,
Mumbai 400 030, Maharashtra, India, an Indian Company
Inventor:
Kamble Ramesh of Crompton Greaves Ltd, FHP Motors division, Kundaim Industrial Estate, Kundiam, Ponda, Goa 403115, India, an Indian National.
PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed

FIELD OF THE INVENTION:
This invention relates to the field of mechanical engineering.
Particularly, this invention relates to spring loaded pad locating clamping structure adapted to locate a pad onto another element.
BACKGROUND OF THE INVENTION:
A pad is generally welded on a shell so as to provide a gripping means for further associated assemblies. To weld the pad on shell, it is important to locate it on at an accurate pre-defined position on the external circumference of the shell. The task of locating the pad was cumbersome as it includes excessive manual labor and precision.
Figure 1 illustrates a prior art equipment and method for locating the pad onto the shell.
Generally the pad was placed on the shell and tightened using screws (02) using a locator device (04). The manual adjustment of screws was never perfect which leads to changes in final positioning of the motor in the shell. This caused rejections, at the final stage of delivery, due to misaligned pads. Even the defective pads were not identified because of manual adjustment of the screws on the pad. Further, with the constant use of screws, due to wearing in the screw length the positioning of the pad may get distorted. The use of manual screws adjustment generally takes 30-40 seconds for locating one pad, which in turn reduces the final productivity.

Hence, there is a need for an automated screw adjustment for locating the pad onto another element (shell) which can be achieved in a fewer span of time.
OBJECTS OF THE INVENTION:
An object of the invention is to provide pad locating fixture for welding pads of motors with reduces the cycle time of locating and fixing.
Another object of the invention is to provide a pad locating fixture for welding pads with mounting of pad on shell of the motor.
SUMMARY OF THE INVENTION:
For the purposes of this invention, a 'pad' is an auxiliary element adapted to be fixed on to a main (another) element, firstly by accurately locating said pad on said element.
According to this invention, there is provided a spring loaded pad locating clamping structure adapted to locate a pad onto another element, said structure comprises:
a. first elongate element adapted to provide support for said spring
loaded pad locating clamping structure;
b. second elongate element placed parallel to said first elongate element
and spaced apart from said first elongate element;

c. resilient means adapted to be placed in the space between said first
elongate element and said second elongate element in order to
resiliently connect said first elongate element with said second
elongate element;
d. lever which upon engaging is adapted to resiliently pull said second
elongate element towards said first elongate element, and which
further allows movement of said second elongate element away from
said first elongate element upon disengaging said lever; and
e. locating means adapted to receive said pad in order to locate said pad
onto another element due to the resilient action, wherein the second
elongate element moves away from said first elongate element helps
to clamp the pad, placed on the locating means, onto said another
element.
Typically, said structure includes two said locating means.
Typically, said locating means is placed at a pre-determined height on said second elongate element.
Typically, said first elongate element and said second elongate element are fabricated of pre-defined heights in order to locate said pad at a defined height on said another element.
Typically, said structure is placed on a base plate having an inner diameter complementing the diameter of said another element in order to receive said another element.

BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS:
Figure 1 illustrates a clamping structure of the prior art.
The invention will now be described in relation to the accompanying drawings, in which:
Figure 2 illustrates a side view of the spring loaded pad locating clamping structure; and
Figure 3 illustrates a back view of the clamping structure of Figure 2.
DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS :
According to this invention, there is provided a spring loaded pad locating clamping structure (100) adapted to locate a pad onto another element.
Figure 2 illustrates a side view of the spring loaded pad locating clamping structure according to this invention; and Figure 3 illustrates a back view of the clamping structure of Figure 2.
In accordance with an embodiment of this invention, there is provided a first elongate element (12) adapted to provide support for said spring loaded pad

locating clamping structure. Typically, the first elongate element is made of metal and is vertically placed in its operative configuration.
In accordance with another embodiment of this invention, there is provided a second elongate element (14) placed parallel to said first elongate element and spaced apart from said first elongate element.
In accordance with yet another embodiment of this invention, there is provided a resilient means (16) adapted to be placed in the space between said first elongate element and said second elongate element in order to resiliently connect said first elongate element with said second elongate element.
In accordance with still another embodiment of this invention, there is provided a lever (18), which upon engaging is adapted to resiliently pull said second elongate element towards said first elongate element, and which further allows movement of said second elongate element away from said first elongate element upon disengaging said lever.
In accordance with an additional embodiment of this invention, there is provided at least a locating means (20) adapted to receive said pad in order to locate said pad onto another element. Typically, two such locating means are provided.
Typically, the locating means is placed at a pre-determined height on said second elongate element. Typically, said first elongate element and said

second elongate element are fabricated of pre-defined heights in order to locate said pad at defined height on said another element.
The resilient action, wherein the second elongate element moves away from said first elongate element helps to clamp the pad, placed on the locating means, onto said another element.
In accordance with yet another additional element of this invention, there is provided a base plate (22) having an inner diameter complementing the diameter of said another element in order to receive said another element. Typically, said another element is a shell.
Typically, an arm extends orthogonally vertical to said base plate, which arm is said first elongate element.
Due to the tension generated by expansion of resilient means the pad will be firmly located on the shell for welding purpose. The pins present in the pad locater strip helps in detecting the defective pad. At the time of mounting if the pad is defected, the pins will not match with the holes on the pad.

We claim,
1. A spring loaded pad locating clamping structure adapted to locate a pad onto another element, said structure comprising:
a. first elongate element adapted to provide support for said spring
loaded pad locating clamping structure;
b. second elongate element placed parallel to said first elongate element
and spaced apart from said first elongate element;
c. resilient means adapted to be placed in the space between said first
elongate element and said second elongate element in order to
resiliency connect said first elongate element with said second
elongate element;
d. lever which upon engaging is adapted to resiliency pull said second
elongate element towards said first elongate element, and which
further allows movement of said second elongate element away from
said first elongate element upon disengaging said lever; and
e. locating means adapted to receive said pad in order to locate said pad
onto another element due to the resilient action, wherein the second
elongate element moves away from said first elongate element helps
to clamp the pad, placed on the locating means, onto said another
element.
