The invention discloses a
welding robot based on a rectangular coordinate
system. In terms of an X axis, a
machine base, a guide rail, an X-axis sliding platform, a motor, a planetary gear
reducer, a gear and a rack are arranged, the motor drives the planetary gear
reducer to rotate and the gear rotates to drive the sliding platform to move on the guide rail. In terms of a Y axis, a Y-axis
cantilever, a motor, a planetary gear
reducer, a Y-axis sliding platform, a guide rail, a gear, a rack and a wire feeder are arranged and a motor drives the planetary gear reducer to rotate, so that the gear and the rack are in matched transmission to drive the Y-axis
cantilever to move on the sliding platform. In terms of a Z axis, a Z-axis
cantilever, a motor, a planetary gear reducer, a Z-axis sliding platform, a guide rail, a gear and a rack are arranged and the motor drives the planetary gear reducer to rotate, so that the gear and the rack are in matched transmission to drive the Z-axis cantilever to move on the sliding platform. In terms of a U axis, a U-axis motor installation plate, a motor, a planetary gear reducer and a U-shaped
flange are arranged and a motor rotates to drive the
flange to rotate. In terms of a W axis, a W-axis motor installation plate, a motor, a clamp and a
welding gun are arranged and the motor rotates to drive the
welding gun to rotate. The welding
robot based on the rectangular coordinate
system is simple in structure, convenient to use and capable of reducing cost.
