Abstract
The connecting rod is one of motor car engine main power transmission components, often being at the high speed state of motion, therefore, which requests the higher grade of fit with other components. Thus the connecting rod is examined in the production to be frequent and the also essential link. The connecting rod parallelism measuring instrument is specially for examines for measuring tool which the automobile connecting rod design, its structure is simple, the measuring accuracy is high. This design is composed by the mechanical system design and the control system design, which includes the gear drive design and the choice, the ball bearing guide screw design and chooses, motor machine choice and installment mechanical system design, relating test system control design and choice. My design content mainly focuses on the machine part design.
