According to the function accomplished by the work table, the work table has 4 DOF(degree of freedom), with 3 translations and 1 rotation, and then the feed motion of semi-tube is available. Then this paper puts forward 3 feasible schemes, after analyzing and comparing, each scheme has its good point and bad point ,from the aspect to consider, the easiness of entrance to the system and dismount and transfer ,the scheme consists of a main work table and a subsidiary work table is selected as the general structure scheme. Detail design of the specific mechanism and the choose of main standard components is processed on the base of the general structure . This paper calculates the strengthen and stiffness of some components.
