Positioning device for inner girth welding

Abstract

The invention discloses a positioning device for inner girth welding, comprising a bearing table. An electric control box is arranged on one side of the bearing table, a trapezoidal support is installed on the upper portion of the bearing table, a machining platform is installed on the upper portion of the trapezoidal support, an upper sliding frame is installed on the lower portion of the trapezoidal support, a concave base is installed in the middle of the upper surface of the bearing table, a damping spring is installed between the upper sliding frame and the concave base, T-shaped sliding grooves are symmetrically formed in the two side faces of the machining platform, a positioning plate is fixedly connected to the position, close to the end, of the upper portion of the machining platform, a movable plate is movably installed on the upper portion of the machining platform, and the two side faces of the movable plate are fixedly connected with side plates. By designing the trapezoidal support below the platform, the upper sliding frame and the concave base below the trapezoidal support, the trapezoidal support and the upper sliding frame and the concave base are clamped in a sliding mode, the damping spring is arranged between the upper sliding frame and the concave base, and therefore vibration is buffered when machining is conducted on the platform, and the machining accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of positioning devices, and in particular relates to a positioning device for inner circular seam welding. Background technique [0002] First of all, the welding automatic machine is based on the product, which is highly specialized and automatically completes the processing task on one machine; while the welding center uses a certain welding process (such as automatic welding of the outer longitudinal seam of the container cylinder or inner ring seam) Automatic welding) as the object, organize the welding equipment and auxiliary equipment required to complete the welding process, and realize the production process through online. As long as the product structure is similar and the process is the same, welding can be carried out. From this feature, it can be seen that the flexibility of the welding center is very flexible. Its main purpose is to modularize each link and carry out professional reorganizatio...

Problems solved by technology

[0003] At present, the positioning device used for inner ring seam welding has cumbersome positioning steps and cannot be positioned stably. It is prone to deviation during processing, and at the same time, it is prone to failure of parts inside the control box. Due to the complicated internal circuit, it is laborious to check. And the welding platform has a poor shockproof effect, so we propose a positioning device for inner ring seam welding
