Specific embodiment
With reference to the accompanying drawing and embodiment is described in further detail technical solution of the present invention.
Embodiment one, as shown in Figure 1, 2, 3, a kind of adjustable Loading for actuator device of linear torque, including pedestal 9, silk
Thick stick 2, lead screw slide 3, angular transducer 7, mounting flange 10, extension spring 4, rocker arm 5 and mounting base 8, lead screw 2 are fixedly connected
On 9 upper surface of pedestal, the sliding of lead screw slide 3 is fitted on lead screw 2, and the end of lead screw 2 is fitted with handwheel 1, by rotating hand
1 is taken turns to drive lead screw 2 to be driven；Bracket is provided on lead screw slide 3, bracket is the L shape knot being integrally formed by bottom plate and side plate
Structure, the bottom plate of bracket are fixedly connected on the upper surface of lead screw slide 3, and the angular transducer 7 is fixedly connected on the side of bracket
On plate, it is connected with mounting flange 10 in the shaft of angular transducer 7, the edge of 10 front end face of mounting flange is provided with connection
One end of column, extension spring 4 is connected on connecting column, and the other end of extension spring 4 is connected to one end of rocker arm 5, rocker arm 5
The other end be connected on the output shaft of tested steering engine 6, tested steering engine 6 is fixedly connected in mounting base 8, and mounting base 8 is fixed to be connected
It connects on 9 upper surface of pedestal, the central axis of the central axis of angular transducer 7 and tested 6 output shaft of steering engine is located at same water
In plane.
In the present invention, the both ends of rocker arm 5 are provided with connecting hole, the company of being fitted in the connecting hole of 5 one end of rocker arm
The other end of outbound, the extension spring 4 is connected on connecting pin, rocker arm 5 by the connecting hole of its other end be fitted in by
It surveys on the output shaft of steering engine 6, also, is interference fit between the connecting hole of 5 other end of rocker arm and the output shaft of tested steering engine 6
Relationship.
As a preferred solution of the present invention, being tested mounting height of the steering engine 6 in mounting base 8 can adjust, in this way can be with
The central axis of the central axis and tested steering engine output shaft that ensure angular transducer is located in same level.
