Construction steel bar butt welding positioning fixture based on air flow

Abstract

The invention relates to the technical field of construction production, and discloses a construction steel bar butt welding positioning fixture based on air flow. The construction steel bar butt welding positioning fixture comprises a construction steel bar, a steel bar positioning butt joint mechanism, an electric welding machine lifting mechanism, a welding mechanism and an air flow pressing mechanism, wherein the steel bar positioning butt joint mechanism comprises an auxiliary bearing, a hydraulic pump, a hydraulic rod, a steel bar inserting pipe, an upper positioning bolt, a lower positioning bolt, a side edge positioning bolt, a rotating handle, a fixed inserting plate, an inserting annular plate, an inserting notch and a fixed inserting rod. High-stability butt joint of welded products and flexible adjusting and fixing work of welding equipment are achieved, splashing of sparks is effectively avoided, safety is enhanced, and the situations that high welding requirements cannotbe met through manual welding, particularly, some high-specification steel bars cannot be held by manpower possibly and the welding quality is poor due to the fact that manual welding processing is difficult to control welding points for a long time are avoided.

Description

Technical field[0001]The invention relates to the technical field of construction production, in particular to a positioning fixture for butt welding of construction steel bars based on air flow.Background technique[0002]Building steel reinforcement welding is to use electric welding equipment to lengthen or connect the steel bars in the axial direction. In the past, when the construction steel welding machine was working, it was generally used to manually add supporting and stabilizing equipment to place and fix the building steel before welding. With the development of construction, the requirements for steel welding production are getting higher and higher. It cannot be done manually, especially for some steel bars with higher specifications, which may not be controlled by manpower. Manual welding is difficult to control the welding point for a long time, resulting in poor welding quality, and during welding work , The sparks produced by welding can easily cause physical damage t...

Problems solved by technology

[0003] The invention provides a butt welding positioning fixture for building steel bars based on air flow. The butt welding positioning fixture for building steel bars based on air flow solves new requirements that cannot be completed by manual welding, especially for some high-standard steel bars. Manpower may not be able to control it, and manual welding processing is difficult to control the welding point for a long time, resulting in poor welding quality, and when welding, the sparks generated by welding can easily cause certain damage to people who are close to the welding position. bodily impairment issues
