Surfacing device of inner wall in deep hole

Abstract

The invention discloses a surfacing device of a inner wall in a deep hole. The device comprises a machine frame and a welding gun assembly, wherein the machine frame comprises a pair of stand columnsand a cross beam, sliding rails are arranged on the inner sides opposite to the stand columns correspondingly, a sliding block is connected to each sliding rail in a sliding mode, and a lifting plateconnected between the sliding blocks is arranged below the cross beam; a rotating disc is connected below the lifting plate, an adjusting sliding groove is formed in the bottom face of the rotating disc in the radial direction, and a welding gun mounting base is slidably connected on the adjusting sliding groove in a clamped mode; the welding gun assembly comprises a welding gun main body and a wire feeding guide pipe, wherein the welding gun main body is vertically arranged, the upper end of the welding gun main body is fixed to the welding gun mounting base, and the lower end of the weldinggun main body is connected with a deep hole extension pipe arranged vertically; and the lower end of the deep hole extension pipe is connected with a variable-direction bend head, a welding head is connected to the end part, far away from the deep hole extension pipe, of the variable-direction bend head, the wire feeding guide pipe is arranged close to the deep hole extension pipe, one end of thewire feeding guide pipe is fixed to the welding gun main body, and the other end of the wire feeding guide pipe faces the welding head. According to the device, the surfacing device of the inner wallin the deep hole is reasonable in structure, the surfacing of the inner wall in the deep hole can be effectively carried out.

Description

technical field [0001] The invention relates to a deep hole inner wall surfacing welding device. Background technique [0002] In the petroleum machinery and shipbuilding industry, in order to meet the performance requirements required by the material, a layer of dissimilar materials is often surfacing on the surface of the workpiece. On the basis of meeting the requirements of the workpiece, such as: hardness, fatigue performance, corrosion performance, etc., the surfacing welding process can reduce the requirements on the performance of the base metal, which can greatly save precious materials and reduce production costs. It is difficult to carry out surfacing welding. Most of the existing surfacing welding devices are aimed at the surface surfacing welding of workpieces, and it is often difficult to meet the requirements of deep hole surfacing welding. Contents of the invention [0003] The object of the present invention is to provide a deep hole inner wall surfacing ...
