Reduction gear housing of fork-lift truck is a machine part having complex structure. Thus, we cannot use available fixture during manufacturing process. Designing and manufacturing a specialized fixture is a requirement. In this study, it is aimed at designing specialized fixture based on drawing of gear housing; its technical and technological requirements and designing manufacturing process this fixture. The designed fixture has main parts is bearing plate, two bolster plates, collet chuck. The manufacturing process includes manufacturing bearing plate, bolster plates and collet chuck, thermal treatment, checking process and assembly. Checking and using test results show that designed fixture is reasonable and manufacturing process reaches technical requirements.
