Field of Invention
The present invention relates to a method for performing auto priming and load testing for chain tensioners and more particularly it relates to an apparatus for auto successive priming and load testing of chain tensioners which provides an economical and efficient solution for enhancing priming, load testing in chain tensioners and ensure to operate safely without failure.
Background of Invention
The chain tensioner for an engine timing drive chain when in order to avoid loosening of the chain even at high speeds of the engine generated vibrations and the engagement failure and other issues. An output characteristic of the displacement force in the chain tensioner piston stroke, i.e. thrust performance, and the displacement amount of retraction of the piston when the pressure loading at a certain position, i.e. compression performance is an important feature of the performance evaluation of the chain tensioner. Research on performance testing means the chain tensioner, the conventional ball screw or a linear motor to control the cylinder piston displacement, a force which can be displaced in the characteristic test of the piston stroke, but pressure loaded piston, the biasing force is rising rapidly, not only cannot achieve the setting load, and likely to cause permanent damage to the device. The use of the cylinder structure, the piston can be loaded to, but not easy to achieve precise control of the piston displacement, and the like require an air supply valve pneumatic components, a control method is complicated and costly.

A chain in its lifetime goes through a lot of stress and jerks which cause it to loosen up. This ends up a maintenance task of adjusting the chain for optimum slack and tightening from time to time. This varies from bike to bike. Plus with the country obsessed with a lot of commuter bikes, they have their chains covered and not exposed. So the option of adjusting the chain slack is one tedious and hence rare one.
The chain tensioner is connected to the chain drive with an adjustment to give the chain some stretch so as to gain optimum slack and tightness to the chain operation. This not only allows for the chain to work properly but due to high slack, the power transmission to the rear wheel also takes a hit and that is recovered as well.
With all said and done, the chain tensioner also does bring certain maintenance factor to it as well. One has to keep the chain tensioner clean and lubricated to as to not increase excess friction but there should also not be any slippages taking place.
In the prior arts priming and load testing of tensioners has been performed manually. As the Manual testing is the oldest and most rigorous type of software testing. Manual testing requires a tester to perform manual test operations on the test software without the help of Test automation. Further, load testing and performance testing is not possible in manual testing.

In the prior arts testing cases are usually executed by human tester and it is usually a very slow process. Another complicating factor is that more manual interaction needed during the process. More spacing is required for performing different test on same product thus testing process becomes more costly.
Therefore, it is desperately needed to develop an apparatus for auto successive priming and load testing of chain tensioners which overcomes the aforesaid drawbacks and limitations of the prior arts.

It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.
The present invention relates to an apparatus that is capable of enhancing priming, load testing in chain tensioners and ensure to operate safely without failure.

Before explaining the present invention, it is to be understood that "an apparatus" is a generic term commonly used for the technical equipment or machinery needed for a particular activity or purpose.
Further, the term "successive priming and load testing of chain tensioners", hereinafter described, being used for performing load testing and priming in a regular sequence without any skip or break.
It is to be also understood that the term "comprises" and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, etc are optionally present. For example, an article "comprising" (or "which comprises") components A, B, and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components A, B, and C but also contain one or more other components.
Now, in embodiment shown in Fig.l, an apparatus for auto successive priming and load testing of chain tensioners (1) according to the present invention comprises a robo cylinders (2) being mounted above the fixture (11) being connected with pic control system (8) receives a control signal from pic control system (8) and an priming servo motors (3) being mounted at bottom of the robo cylinders (2) working as an rotary actuator responds by converting the signal's energy into mechanical motion. Further, fixture (11) is being mounted above the load testing load cells (9) to securely locate (position in a specific location or orientation)

Now, pic control system (8) being connected with pc (7) to run or control an entire system.
In operational characteristics of the present invention, the tensioner parts (10) being loaded on the said fixture (11) where the said clamping cylinders (5) clamped the said tensioner parts (10). Further said robo cylinders (2) being located above the said load testing load cells (9) starts moving downwards towards the said clamped tensioner parts (10) with the help of said priming servo motors (3) being connected by pic control system (8). Further, after coming in contact with said tensioner parts (10) said robo cylinders (2) starts priming process (Priming process includes checking screw, nut free movement, spring presence, component struck up and the tensioner required torque) by three times. After priming process the said robo cylinders (2) kept holding the tensioner parts (10) until the said load testing load cells (9) comes in contact with tensioner parts (10) with the help of said load testing servo motors (4) which is being
