Embodiment 1
[0042] Such as Figure 1-4, automatic welding robot, including robot arm 1, welding head 2 and wire feeding mechanism 3, said robot arm 1 includes base 1-1, upper arm 1-2, forearm 1-3 and finger arm 1-6, said upper arm 1 -2 is connected to the base 1-1 through the upper arm elbow 1-4, the upper arm elbow 1-4 can be horizontally rotatably installed on the base 1-1, the upper arm elbow 1-4 is rotated by the motor, and one end of the upper arm 1-2 is hinged on the upper arm elbow 1-4, the upper arm 1-2 is driven by the motor to swing, the other end of the upper arm 1-2 is connected to the forearm 1-3 through the forearm elbow 1-5, the upper arm 1-2 is hinged with the forearm elbow 1-5, and the forearm elbow 1- 5. Driven by the motor to swing, one end of the forearm 1-3 can be rotatably mounted on the forearm elbow 1-5, the forearm 1-3 is driven to rotate by the motor, the other end of the forearm 1-3 is hinged with the finger arm 1-6, and the finger arm 1 -6 is driven by the mot...
Embodiment 2
[0050] Such as Figure 5 , Image 6 In this embodiment, on the basis of Embodiment 1, the device is provided with a wire reel mount 6 on the base 1-1, and the wire reel mount 6 is rotatably mounted on the base 1-1.
[0051] The wire reel mounting seat 6 includes a mounting frame 6-1 and a rotating disk 6-2, the mounting frame 6-2 is fixedly arranged on the rotating disk 6-2, and the rotating disk 6-2 is rotatably mounted on the base 1-1, The rotating disk 6-2 is driven to rotate by the welding wire reel motor 6-3.
[0052] Mounting frame 6-1 is exactly a mounting column 6-4 and rotating bar 6-5, and welding wire reel 6-6 is enclosed within on the rotating bar 6-5, fixes with nut again, and welding wire reel 6-6 axially fixes, but can Rotate the wire, and the mounting frame 6-1 is driven to rotate by the rotating disk 6-2 to offset the self-rotation of the welding wire.
Embodiment 3
[0054] Such as Figure 7 In this embodiment, on the basis of Embodiment 1, the device is provided with anti-slip lines 5-6 perpendicular to the axial direction on the surface of the drum 5-5.
[0055] The device is covered with a non-slip rubber layer 5-7 on the cylinder 5-5.
[0056] This embodiment can prevent the welding wire 4 from slipping during transmission, because the welding wire 4 enters the delivery pipe 2-1 and advances in a spiral, and the resistance during advancement is much larger than that of a common welding head.

Abstract
The invention discloses an automatic weldingrobot. The automatic weldingrobot comprises a machine arm, a welding head and a wire feeding mechanism. The pipe wall of a delivery pipe is provided witha spiral line. The wire feeding mechanism is arranged at an inlet of the delivery pipe. The wire feeding mechanism is mounted on a finger arm and comprises a movable pulley and a stationary pulley. The movable pulley is driven to rotate by a wire feeding motor. A solder wire is clamped between the movably pulley and the stationary pulley. The wheel surface of the movable pulley and the wheel surface of the stationary pulley are both provided with a circle of V-shaped grooves. The two sides of each V-shaped groove are provided with symmetrical rollers. The automatic welding robot has the advantages that the inner wall of the delivery pipe is provided with a thread, so that the solder wire is forced to rotate in the conveying device; in the welding process, the solder wire droops under hightemperature, is rotated to deflect and restores when bent upwards; during welding, deviation of soldering points is greatly reduced, the welding accuracy is improved, and the welding quality is improved.
Description
technical field [0001] The invention relates to the fields of welding machines and mechanical automation, in particular to an automatic welding robot. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization (ISO) that an industrial robot belongs to a standard welding robot, an industrial robot is a multipurpose, reprogrammable, automatic controlmanipulator with three or more programmable axes, used in the field of industrial automation . [0003] With the development of electronic technology, computer technology, numerical control and robot technology, the technology of automatic welding robot has become increasingly mature since it was used in production in the 1960s. The quality is reflected in the form of numerical values; 2) Improve labor productivity; 3) Improve the labor intensity of workers and work in harmful environment...
