Embodiment 1
[0035] The overall structure diagram of the travel limit device of this embodiment when it cooperates with other components is as follows figure 1 As shown in the figure, the travel limit device, the rotating shaft, the motor and the reducer are all installed on the platform, the load is fixed on the platform through the rotating shaft, and the pitching motion can be performed. The motor drives the reducer to rotate and passes the gear on the reducer and the load on the The tooth arc plate teeth mesh. When the load rotates to a predetermined angle under the action of the motor and the reducer, it connects with the spring stroke shaft of the new stroke limit device. When it continues to move, the spring stroke shaft is compressed by external force. Under the action of its internal mechanism, the first trigger The microswitch contacts give an electrical signal indicating that the load is in place, and the drive motor controller cuts off the power to the motor. The load continue...
Embodiment 2
[0037] The specific structure of the stroke limiting device in this embodiment is as follows: Figure 2-6 Shown: mechanical limit Implementation: the limit switch box 1 is a carrier for component installation, the rubber pad 3 is installed on the side of the limit switch box through screws 17, and the rubber material is hard rubber.
[0038]Electric limit implementation: the spring travel shaft 5 and the travel control switch 2 are the two main assemblies for implementing the electric limit. The spring travel shaft 5 is fixed by the face plate nut 4 and the long cylindrical hole on the side of the limit switch box 1. The hollow shaft 15 can be freely extended and retracted in the cylindrical hole. The face plate nut 4 is an external thread ring structure, and the limit switch box 1. Match with the internal thread on the top. The central shaft 13 is placed inside the spring 14 , and the spring 14 is placed inside the hollow shaft 15 . When the hollow shaft 15 is compressed, i...
