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 casing 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 bottom...

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...

Abstract

The invention provides a robot welding-cutting anti-collision device. The robot welding-cutting anti-collision device is characterized in that the robot welding-cutting anti-collision device comprisesa mandrel, a cover plate, a reset plate, an auxiliary spring and a shell; the mandrel is of a hollow structure, one end of the mandrel is provided with a welding gun, and the other end of the mandrelis connected with a reset plate; the reset plate is in a cake shape, and is installed at one end of the mandrel in a sleeving mode and fixedly connected with the mandrel; the shell is divided into anopen end and a bottom, and the center of the bottom is provided with a round through hole; the cover plate is installed at the open end of the shell, the middle of the cover plate is provided with around through hole, and the round through hole is used for allowing the mandrel to pass, does not make contact with the mandrel and is away from the mandrel by a certain distance; the end, provided with the reset plate, of the mandrel is in pressing connection with the inner bottom of the shell through the auxiliary spring; and the cover plate makes plane contact with the reset plate, and the cover plate and the reset plate have the precise positioning and reset functions. The robot welding-cutting anti-collision device is low in collision torque, high in repetition precision, balanced in collision force, wide in working range and capable of achieving precise reset after collision in any direction.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to a robot welding and cutting anti-collision device. Background technique [0002] Welding robots are industrial robots engaged in welding. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be equipped with welding tongs or welding torches to achieve welding, cutting or thermal spraying. During the operation of the welding robot, due to the irregular changes of the welding seam, the welding torch installed at the end of the robot will occasionally encounter the workpiece and other obstacles, resulting in damage to the welding torch and offset of the welding position, affecting the safety of production and operation , causing the welding torch to be scrapped in a slight case, and causing damage to the robot or the operator in a serious case. Therefore, it is necessary to install an anti-...
