Problems solved by technology

With the development of TIG arc surfacing technology, the current research on TIG arc surfacing is not limited to simple straight wall parts or cylindrical parts, but due to the limitations of most of the existing TIG arc surfacing equipment itself, It basically does not have or cannot process complex parts such as S-type, W-type, Z-type, or even oblique surfacing.

Abstract

The invention discloses a three-degree-of-freedom water cooling workbench for TIG automatic surfacing. The three-degree-of-freedom water cooling workbench mainly comprises an upper swinging mechanism, a middle slewing mechanism and a lower linear feeding mechanism which are sequentially arranged from top to bottom, wherein the upper swinging mechanism comprises a workbench body, a fan-shaped swinging part and a piezoelectric ceramic motor; the fan-shaped swinging part is vertically arranged; a circular arc of the fan-shaped swinging part is at the lower part; the fan-shaped swinging part is fixed to a connecting plate through supporting blocks; the fan-shaped swinging part is connected with the supporting blocks through rotating parts; the fan-shaped swinging part rotates relative to the supporting blocks; a ceramic ring is fixed to the bottom of the fan-shaped swinging part; the workbench body is horizontally fixed to the top of the fan-shaped swinging part; a cooling water circuit is arranged in the workbench body; the piezoelectric ceramic motor is fixed to the connecting plate; and the connecting plate is fixed to a fixed plate. According to the three-degree-of-freedom water cooling workbench, the piezoelectric ceramic motor drives the fan-shaped swinging part to slew at + / - 40 degrees, the workbench body is driven to incline, and a surfacing parent metal is subjected to inclined surfacing.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of arc surfacing welding under the protection of inert gas and 3D forming additive manufacturing, and in particular relates to a three-degree-of-freedom water-cooled workbench for TIG automatic surfacing welding. [0003] Background technique: [0004] Overlay welding is to make the surface of the part obtain a deposited metal with properties such as wear resistance, corrosion resistance, high temperature resistance and oxidation resistance; or to restore or increase the size of the part, a welding method is used to deposit a layer on the surface of the part with specific properties Material welding process. As an economical and effective surface modification method, surfacing welding is an indispensable technological means for modern material processing and manufacturing. At present, there are many surfacing welding methods, and under the promotion of the manufacturing industry, new surfacing weldin...
