Embodiment 1
[0022] Example 1: Such as figure 1 , 2 , Shown in 3, is to be used for reciprocating motion to be the anti-collision limiter that rotates, and reciprocating motion part 3 is a rotating member. The anti-collision limiter of the present invention has a frame 1 and a limit switch 4 fixed on the frame 1 for controlling the operation of the electromechanical system. In this embodiment, the power supply is controlled by the limit switch 4 to control the operation of the servo system motor. There is an elastic lever 6 for opening and closing the limit switch 4; one end of the elastic lever 6 is the front end lever 6.1 that directly toggles the limit switch 4, and the other end is a rear end lever that is fixedly connected with the reciprocating component 3 6.2; fixed on the frame 1 is also a stop pin 5 for limiting the front end driving rod 6.1, and an elastic stopper 2 for limiting the rear end driving rod 6.2. The elastic driving lever 6 is composed of two sections, the front-...
Embodiment 2
[0023] Example 2: Different from Example 1, as Figure 4 , 2 , 3, the reciprocating component 3 is a rectilinear reciprocating component, the rear end lever 6.2 is fixed on the rectilinear block 3.3 with the rectilinear guide rail 3.2, and the rectilinear guide rail 3.2 is fixed on the frame 1.
Embodiment 3
[0024] Example 3: The difference from Embodiment 1 is that the spring 7 is a leaf spring whose two ends are respectively connected to the side surfaces of the front end driving rod 6.1 and the rear end driving rod 6.2. This leaf spring can be one piece, be connected on one side of front-end driving lever 6.1 and rear-end driving lever 6.2; also can be two pieces, be fixedly connected on two sides of front-end driving lever 6.1 and rear-end driving lever 6.2 respectively.
