Wireless-control-based four-degree-of-freedom TIG automatic surfacing rotary workbench

Abstract

The invention discloses a wireless-control-based four-degree-of-freedom TIG automatic surfacing rotary workbench which comprises a Y-axis moving platform and an X-axis moving platform. The Y-axis moving platform is stacked on the upper surface of the X-axis moving platform, a worm-gear speed reducer is fixed on the top face of the Y-axis moving platform, a screw shaft is arranged at the bottom of the Y-axis moving platform, two ends of the screw shaft are fixed on a screw shaft fixing seat, a servo motor is fixed on the side face of the worm-gear speed reducer, the servo motor and a worm shaft inside the worm-gear speed reducer are fixedly connected through a coupler, a turnplate disc is fixed on the top face of the worm-gear speed reducer, the bottom of the X-axis moving platform is fixed on a base turnplate disc, a screw shaft is arranged at the bottom of the X-axis moving platform, two ends of the screw shaft are fixed on a screw shaft fixing seat, and the servo motor on the Y-axis moving platform and a servo motor at the bottom of the X-axis moving platform are in cross distribution. Motion of the servo motors of the degrees of freedom is controlled wirelessly to be in synthesis motion, and shape tracks of needed surfacing complex parts can be synthesized.

Description

Technical field [0001] The invention relates to a rotary workbench, in particular to a four-degree-of-freedom TIG automatic surfacing welding rotary workbench based on wireless control, belonging to the technical field of arc surfacing welding under inert gas protection and 3D forming additive manufacturing. Background technique [0002] At present, the research on TIG welding arc surfacing is applied to surfacing simple straight wall parts or cylindrical parts. And affected by the welding characteristics of TIG welding itself, the quality of the surfacing welding is easily affected by many factors, so the surfacing of complex parts is greatly restricted. The current TIG welding surfacing method is mainly mobile TIG welding torch surfacing parts. This method is easy to cause instability of wire feeding and affect the quality of molding. In addition, the surfacing of the mobile welding gun is restricted by the wire feeding direction and the wire feeding angle, and it is difficul...

AI Technical Summary

Problems solved by technology

This method is likely to cause instability in wire feeding and affect molding quality.

In addition, the surfacing welding of the moving welding torch is limited by the wire feeding direction and wire feeding angle, and it is difficult to stack complex parts such as S-shaped, V-shaped, W-shaped, Z-shaped, etc. and their combinations
