FIELD
The present disclosure relates to the field of oil seals.
BACKGROUND
The background information herein below relates to the present disclosure but is not
necessarily prior art.
Clutch actuator guides of vehicles are usually hydraulically controlled elements.
Hence, clutch actuator guides tend to attract foreign particles and dirt towards itself
which tend to adversely affect the performance of the clutch actuator guides and
corresponding components. Additionally, the fluid controlling the working of the
clutch actuator guides can leak and reach out to other components like friction liners,
thereby again causing a detrimental situation. Hence, it is necessary that a clutch
actuator guides should remain sealed by means of an oil seal.
However, sometimes while assembling the clutch actuator guide, an operator may
forget to install the oil seal on the clutch-actuator guide, and the defective clutch
actuator guide will be carried forward to be assembled into the vehicle, thereby
affecting the performance and life of the vehicle.
There is, therefore, felt a need of a tool for indicating absence of oil seal on a clutchactuator
guide.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein
satisfies, are as follows:
One object of the present disclosure is to provide tool for indicating absence of oil
seal on a clutch-actuator guide.
Another object of the present disclosure is to provide a tool that has a simple
configuration.
Other objects and advantages of the present disclosure will be more apparent from the
following description, which is not intended to limit the scope of the present
disclosure.
SUMMARY
The present disclosure envisages a tool for indicating absence of an oil seal on a
clutch actuator guide during the oil seal mounting process. The tool comprises a
body. A clamping head is configured at an operative upper portion of the body. The
clamping head is configured to be fitted to an upwardly displaceable ram of a press
machine. A pressing head is configured at an operative lower portion of the body.
The pressing head is configured to removably secure an oil seal thereon. The pressing
tool is further configured to facilitate pressing of the oil seal onto the clutch actuator
guide. A plurality of magnets is attached to the body. Absence of an oil seal exposes
the clutch actuator guide to the magnetic force exerted by the tool, thus causing the
clutch actuator guide to stick to the tool and indicate the absence of the oil seal on the
clutch actuator guide.
In an embodiment, the clamping head is a shank configured to securely fit the tool in
the press machine.
In another embodiment, the pressing head is provided with a seal mounting face
configured to allow the oil seal to be removably pressed thereon.

present disclosure to the person skilled in the art. Numerous details are set forth,
relating to specific clutch-actuator guides to provide a complete understanding of
embodiments of the present disclosure. It will be apparent to the person skilled in the
art that the details provided in the embodiments should not be construed to limit the
scope of the present disclosure. In some embodiments, well-known apparatus,
structures, and well-known techniques are not described in detail.
The terminology used, in the present disclosure, is only for the purpose of explaining
a particular embodiment and such terminology shall not be considered to limit the
scope of the present disclosure. As used in the present disclosure, the forms "a", "an"
and "the" may be intended to include the plural forms as well, unless the context
clearly suggests otherwise. The terms "comprises", "comprising", "including" and
"having" are open-ended transitional phrases and therefore specify the presence of
stated features, elements, modules, units and/or clutch-actuator guides, but do not
forbid the presence or addition of one or more other features, elements, clutchactuator
guides, and/or groups thereof.
When an element is referred to as being "mounted on", or "coupled to" another
element, it may be directly mounted on, or coupled to the other element. As used
herein, the term "and/or" includes any and all combinations of one or more of the
associated listed elements.
Terms such as "below", "lower", "above" and the like, may be used in the present
disclosure to describe relationships between different elements as depicted from the
figures.
Conventionally followed method of inspecting an oil seal on a clutch-actuator guide
involves manual inspection of each and every clutch-actuator guide. The conventional
method is not only tedious but also unreliable. There is always a probability of
defective clutch-actuator guides without oil seals going further and being assembled
into vehicles.
A tool (100), of the present disclosure, for indicating absence of oil seal on a clutchactuator
guide will now be described in detail with respect to Figure 1A through
Figure 3. The preferred embodiment does not limit the scope and ambit of the
disclosure.
The tool (100) is configured to indicate the absence of the oil seal during the oil seal
mounting process.
The tool (100) is a magnetized pressing tool (100). The tool (100) comprises a body
(100A), a clamping head (100B) configured at an operative upper portion of the body
(100A) and a pressing head (not specifically shown in figures) configured at an
operative lower portion of the body (100A). The clamping head (100B) is configured
to be fitted to an upwardly displaceable ram of a press machine (105). The pressing
head is configured to removably secure an oil seal (102) thereon. The pressing head is
further configured to facilitate pressing of the oil seal (102) onto the clutch actuator
guide (104). The tool (100) includes a plurality of magnets (106) attached to the body
(100A).
The clutch-actuator guide (104) is positioned on a base fixture (not specifically
shown in figures) of the press machine (105).
In an embodiment, the ram is provided with a tool holding clamp having a cavity
provided with a hole for facilitating fitting of the clamping head (100B) with the ram.
In another embodiment, the tool holding clamp includes fastening means for securing
the clamping head (105) therewith.
In an embodiment, the clamping head (100B) is a shank configured to securely fit the
tool (100) in the press machine (105). In another embodiment, the shank has a
threaded body to facilitate mating of the clamping head (100B) with the press
machine (105). In another embodiment, the shank has flanges configured thereon to
facilitate mating of the clamping head (100B) with the press machine (105). The
shank is further provided with an aperture configured to allow mating of the shank
with the fastening means of the tool holding clamp.
The pressing head is provided with a seal mounting face (101) having a profile
complementary to the profile of the oil seal (102). The seal mounting face (101) is
configured to allow the oil seal (102) to be removably pressed thereon. Prior to
initiation of the oil seal mounting process, the oil seal (102) is pressed on the seal
mounting face (101).
The clutch-actuator guide (104) being a ferromagnetic material is attracted to the
magnetized pressing tool (100). However, since the oil seal (102) is of a nonferromagnetic
material such as rubber or polymer, the oil seal (102) acts as a barrier
to the magnetic force exerted by the tool (100). In the absence of an oil seal (102), the
magnetic force exerted by the tool (100) attracts the clutch actuator guide (104)
towards itself and pull the clutch actuator guide (104) along as the tool (100) retracts
back to its original position. The clutch-actuator guide (104) stuck with the tool (100)
thus indicates the absence of the oil seal (102) on the clutch actuator guide (104).
The tool (100) and the clutch-actuator guide (104) stuck together are separated
manually. The clutch-actuator guide (104) is again located on the base fixture.
Thereafter, an oil seal (102) is placed on the tool (100), and is pressed on the clutchactuator
guide (104) with the help of the tool (100).
The tool (100) includes clamping means (108) configured to attach the plurality of
magnets (106) to the tool (100). In an embodiment, the magnets (106) are permanent
magnets.
In another embodiment, the magnets (106) are electromagnets. The tool (100)
includes a voltage source (not specifically shown in figures) configure to supply
power for electro magnetizing the magnets (106).
The tool (100), of the present disclosure, provides a simple solution for indicating the
absence of the oil seal (102) on the clutch-actuator guide (104), and eliminates the
tedious methods of inspection that are conventionally being followed, thus reducing
human error.
The foregoing description of the embodiments has been provided for purposes of
illustration and not intended to limit the scope of the present disclosure. Individual
clutch-actuator guides of a particular embodiment are generally not limited to that
particular embodiment, but, are interchangeable. Such variations are not to be
regarded as a departure from the present disclosure, and all such modifications are
considered to be within the scope of the present disclosure.
