Abstract In the high-pressure, high-speed, high-power manufacturing industry, because of the hydraulic technology, control theory, a microcomputer, test and measurement technology, digital information processing, reliable technology, making the mechanical, electrical, hydraulic equipment integrated in the entire mechanical equipment accounting for the proportion is growing. Hydraulic test stand,as a detection device of hydraulic components, can be used to measure the hydraulic pumps, hydraulic motors, hydraulic valves and other hydraulic components ,and it has also been widely used in many fields.

Hydraulic motors, as one of hydraulic actuator, its product quality directly affect the system performance. Therefore, the accurate testing of the hydraulic motor is to identify strengths and weaknesses, improving structural design, improve the technological level, to ensure system performance and an important way to promote product upgrades.

The main task of the design is to complete the test automatic clamping system based on hydraulic motor performance requirements so that it can achieve the hydraulic motor fastening or moved. This paper describes the technology of hydraulic and pneumatic and hydraulic test bench research status, followed by hydraulic test bench for the mechanical structure, automatic clamping pneumatic system, electrical control system were discussed respectively,and completed the automatic clamping system design eventually.
