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.

Abstract

The invention relates to a collision-damage-prevention stopper which is suitable for a limiting control system with limited travel reciprocating motion. The collision-damage-prevention stopper comprises a rack, a limit switch fixed on the rack for controlling operation of an electromechanical system, and an elastic driving lever for switching on and off the limit switch, wherein one end of the elastic driving lever is a front end driving level for directly driving the limit switch, and the other end of the elastic driving lever is a rear end driving level fixedly connected with a reciprocating motion part; a stop pin for limiting the front end driving level, and an elastic stop dog for limiting the rear end driving level are fixed on the rack. The collision-damage-prevention stopper has the advantages that the accurate limiting requirements in the control system can be met, a mechanism can be effectively protected to avoid damage caused by collision, therefore, the reliability of the system is improved.

Description

technical field [0001] The invention relates to an anti-collision damage limiter, which belongs to the technical field of emergency protection devices in electrical components, and is suitable for a limit control system of reciprocating movement with a limited stroke. Background technique [0002] In the servo system with limited stroke reciprocating motion, in order to prevent the moving parts from flying and causing damage to the cables and parts of the equipment, electrical limit and mechanical limit are usually used to limit the movement of the parts within a specific range. The electrical limit is realized by triggering the limit switch at the corresponding position of the limit lever to turn off the power of the motor. During use, the limit switch is often caused by errors such as the installation position and installation direction of the limit switch and the limit lever. Damaged, or the limit lever crosses the end of the contact piece of the limit switch and damages ...
