a fixture. The main objective of fixture is to hold and locate the work-piece during any machining operation but in our project. We are using fixture as a holding device as well as for quality testing purpose to improve the rate of production without getting a faulty product dispatched. We are using a pneumatic operated fixture for inspection of damper.
fabrication of a shock absorber pulling fixture that will be used to detect sealing missing operation of damper with cycle time reduction. This fixture will assure the sealing which is present in between damper cylinders. The project focuses to reduce customer complaints regarding sudden breakage of damper which causes complete failure of suspension assembly that is fitted at the rear end of piaggio mini truck. In this project scope designing and fabrication of a pneumatically operated fixture has done which increases volume of production with decreased number of faulty products. This report is based on the work undertaken for designing a fixture assembly and testing it in real production system. This system is specifically designed for piaggio mini truck dampers.

1. INTRODUCTION
f. Analysis on Ansys
This project is grounded on the designing and fabrication of a shock absorber pulling fixture that will be used to detect sealing missing operations. A shox absorber is designed to soak up or dampen the contraction. It rebound the springs suspension shock absorbers at all times. It keeps tires in contact with the road when the vehicle hit any dip or bump in a road vehicles at all time. Vehicle suspension and springs move so that the tire will stay in contact with the road and absorb the energy. In Hydraulic fluid shock absorber the shock absorbers dampen the movement of the springs by converting the springs kinetic energy into thermal energy. Also it degenerates when vehicle suspense moves and then piston moves up and down through the oil- filled cylinder. The up and down movement of the piston forces small amount of fluid through orifices in the piston head. Since only a small amount of fluid is forced out, this slows down the suspension movement and dampens the compression and rebound of the springs.

3. PROBLEM STATEMENT The main problem is that while manufacturing the rear side shock absorber (Damper), there is a sealing operation on the upper mount (eye) side where the bushing is mounted upto the sealing. Sealing works as a stopper. From the bushing there is opening for piston and piston rod to gets connected to upper mount (eye).
A fixture plays an important role while manufacturing a product. A fixture is a device for locating, holding and supporting a work-piece throughout a manufacturing operations A fixture is a device used to constrain all degrees of freedom of a work-piece in a given co-ordinate system.
