Servo wire feeding device for automatic welding robot

Abstract

The invention relates to the technical field of welding robots and provides a servo wire feeding device for an automatic welding robot. The servo wire feeding device has a good insulation effect and has functions of dust prevention and chip prevention. The servo wire feeding device comprises a servo wire feeding welding gun body and a linear buffer connected with the tail end of the servo wire feeding welding gun body through a conducting wire cable. The servo wire feeding welding gun body comprises a welding gun shell, a gun nozzle assembly mounted on the front side of the welding gun shell, servo wire feeding motors, wire feeding wheels and a bottom flange, the servo wire feeding motors and the wire feeding wheels are installed in the welding gun shell through a sky beam and a wire drawing base, and the bottom flange is installed on the rear side of the welding gun shell; insulation structures are arranged between the servo wire feeding motors and the wire drawing base, between the wire feeding wheels and the servo wire feeding motors, between the sky beam and the bottom flange, between the wire drawing base and a front flange support, and between a lower housing and the wire drawing base; key groove connecting structures are arranged between the servo wire feeding motors and a wire wheel locating sleeve, and between the wire wheel locating sleeve and the wire feeding wheels; dust prevention structures are arranged between the wire feeding wheels and the wire feeding motors, between the sky beam and the bottom flange, and between the wire feeding motors and the wire drawing base.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to a servo wire feeding device of an automatic welding robot. Background technique [0002] With the wide application of welding robots, the problem of robot wire feeding affecting welding quality has become increasingly prominent, and a high-precision, high-reliability wire feeding method is urgently needed. For example, some welding methods require the welding wire to move repeatedly at high speed, which cannot be solved by traditional wire pushing methods. [0003] The robot welding system with servo wire feeding function mainly includes two parts: welding robot and welding equipment. Among them: welding robot is composed of robot body and control unit (hardware and software); welding equipment mainly includes welding power supply (including its control system), wire feeding mechanism, servo welding torch assembly and other parts. The servo wire feeding torch assembly in...

Problems solved by technology

Finally, there is generally a lot of dust on the welding site, and there is friction between the welding wire, the wire feeding sleeve and the wire feeding wheel during wire feeding, which will cause the welding wire to peel off debris and affect the work of the motor and robot. From the perspective of safety and reliability, It is necessary to design a dust-proof structure between the welding wire and the robot body and the servo wire feeding motor
