Abstract

The invention provides a welding robot device for welding of a plunger pump power end shell. The welding robot device for welding of the plunger pump power end shell comprises a controlling system, a portal frame X-Y-Z coordinate system, a welding system, a space positioner and a tool clamp. The tool clamp is used for clamping the plunger pump power end shell, and a plunger pump shell can be one-time clamped; all welding joints of the plunger pump shell can be positionally changed to a flat welding position or a flat fillet welding position through the space positioner; a welding mechanical arm is connected with a coordinate Z-axis in the portal frame X-Y-Z coordinate system, and welding of welding joints in the different positions can be finished; and synchronized driving of the welding mechanical arm, a coordinate X-axis, a coordinate Y-axis, the coordinate Z-axis and the space positioner can be realized, so that continuity during the welding process is guaranteed, and welding quality and welding efficiency are ensured.

Description

technical field [0001] The invention relates to a welding robot device, in particular to a welding robot device used for welding the casing of the power end of a plunger pump. Background technique [0002] With the rapid development of the petroleum industry, the demand for oil stimulation fracturing equipment is also increasing, and the demand for plunger pumps, the key components of fracturing equipment, is also increasing. Due to the complexity and special-shaped structure of the plunger pump housing, conventional welding Robots are also unable to complete the welding of all welds. At present, the casing of the power end of the plunger pump is manually welded. The plunger pump is a heavy mechanical structure, the welding workload is very large, the efficiency of manual welding is low, and the welding operator is prone to fatigue after long-term work, resulting in welding defects and hidden quality problems. [0003] This patent relates to a welding robot equipment used f...
