Embodiment 1
[0033] Such as Figure 1 ~ Figure 3 As shown, a robot welding and cutting anti-collision device includes a mandrel 3, a cover plate 4, a reset plate 6, an auxiliary spring 7, and a housing 10; wherein, the mandrel 3 is a hollow structure, and a welding torch is installed at one end. There is a U-shaped welding gun positioning keyway on the wall, and the other end is connected to the reset plate 6; the reset plate 6 is round cake-shaped, set on one end of the mandrel 3, and is fixedly connected with the mandrel 3; the shell 10 is divided into an open end and an open end. The bottom and the open end are equipped with a cover plate 4, and the center of the bottom has a circular through hole; the middle of the cover plate 4 has a circular through hole, which is used to pass the mandrel 3 and keep a certain distance without contact with the mandrel 3; The spring 7 is a pressure spring, and one end of the mandrel 3 with the reset plate 6 is pressed and connected with the inner botto...
Embodiment 2
[0041] refer to Figure 1 ~ Figure 3 As shown, a robot welding and cutting anti-collision device includes a mandrel 3, a cover plate 4, a reset plate 6, an auxiliary spring 7, and a housing 10; wherein, the mandrel 3 is a hollow structure, and a welding torch is installed at one end. There is a U-shaped welding torch positioning keyway on the wall, and the other end is connected to the reset plate 6; the reset plate 6 is round cake-shaped, set on one end of the mandrel 3, and is fixedly connected with the mandrel 3; the shell 10 is divided into an open end and an open end. The bottom and the open end are equipped with a cover plate 4, and the center of the bottom has a circular through hole; the middle of the cover plate 4 has a circular through hole, which is used to pass the mandrel 3 and keep a certain distance without contact with the mandrel 3; The spring 7 is a pressure spring, and one end of the mandrel 3 with the reset plate 6 is pressed and connected with the inner bo...
Embodiment 3
[0046] An anti-collision device for robot welding and cutting, including a mandrel 3, a cover plate 4, a reset plate 6, an auxiliary spring 7, and a casing 10; the structures and functions of specific components are the same as those in Embodiment 1.
[0047] The robot welding and cutting anti-collision device provided by the present invention has the following working process: when the welding torch or cutting torch encounters an obstacle when working, the welding torch or cutting torch pushes the mandrel 3 to rotate, and the mandrel 3 is linked with the reset plate 6 to make the reset plate 6 A gap is generated between the cover plate 4 and any one of the 1-N sensors or microswitches 9 receives a signal, and the robot stops moving. During this collision process, after the reset plate 6 is disengaged from the cover plate 4, the suction force of the magnet 8 decreases, the force of the auxiliary spring 7 increases, and the resultant force of the pressure of the auxiliary spring...
