| 摘要 |
The invention concerns a device for transforming alternating rectilinear motion into intermittent rotary motion, in particular for the command of indexed rotary tables. It comprises at least one fixed base element (11) with cam guide means (14), a moving slide element (12) associated with the fixed element, equipped with mechanical locator means (15) following said cam guide means (14) and susceptible to alternating movements on and with respect to said fixed base element commanded by an actuator, and an index plate (13) rotatably associated with the fixed element, interacting mechanically with the moving slide element (12) and susceptible to angular rotation pitch in answer to the alternating movements of said moving slide element. The index plate is connected to an indexed rotary table to be commanded.
