The invention discloses an anti-collision limiting device. The device comprises a contact switch and a buffer, wherein the contact switch is installed on a bottom plate, and the contact switch is provided with a swing part used for triggering the contact switch and enabling the contact switch to generate a contact signal; and the buffer comprises a contact rod, the contact rod is installed on the bottom plate in a sliding mode, the contact rod is connected with an elastic piece used for buffering impact force borne by the contact rod, the contact rod is further connected with a driving piece, the driving piece is provided with a driving face parallel to the sliding direction of the contact rod, one end, close to the swing part, of the driving face is provided with an inverted inclined face smoothly connected with the driving face, after the contact rod is impacted by a moving machine, the contact rod drives the driving part to move synchronously, the driving part extrudes the swing part sequentially through the inverted inclined face and the driving face, and the contact switch generates the contact signal for braking the machine. According to the device, a protection mode of combining the mechanical contact switch and a bumper is adopted, so that the use cost is low, and safety and reliability are realized.
本发明公开了一种防撞限位装置,包括:接触开关,所述接触开关安装在底板上,所述接触开关上设有用于触发并使其产生接触信号的摆动件;缓冲器,所述缓冲器包括接触杆,所述接触杆滑动安装在所述底板上,所述接触杆上连接有用于缓冲接触杆所受撞击力的弹性件,接触杆上还连接有驱动件,所述驱动件上设有与接触杆滑动方向平行的驱动面,驱动面靠近所述摆动件的一端设有与驱动面平滑连接的倒斜面,所述接触杆受到运动机器的撞击力后,所述接触杆带动所述驱动件同步移动,所述驱动件依次通过倒斜面和驱动面挤压所述摆动件,使得接触开关产生制动所述机器的接触信号。本发明采用机械式的接触开关和防撞器相结合的防护形式,使用成本低且安全可靠。
