Abstract
The invention discloses a welding auxiliary device for butt joint of steel pipes with different pipe diameters. The welding auxiliary device comprises a base. A first fixing frame and a second fixingframe are arranged on the left side of the top of the base. A first workbench is fixedly connected to the tops of the first fixing frame and the second fixing frame. An upper clamping plate is fixed through a bolt. The tops of the first fixing frame, the second fixing frame, a third lower clamping plate and a fourth lower clamping plate are all provided with first protective pads. The upper clamping plate is in threaded connection with an adjusting screw rod. The bottom end of the adjusting screw rod is connected with a pressing plate. A third protective pad is arranged at the bottom of the pressing plate. Guide sleeves are correspondingly arranged on the left and right sides of a second workbench. Guide rods penetrate the guide sleeves. A first lower clamping plate, a second lower clamping plate, the third lower clamping plate and the fourth lower clamping plate are all Y-shaped and can fix pipe fittings conveniently and prevent releasing during welding, the adjustment of coaxiality of butt joint of the steel pipes with different pipe diameters is realized, and the welding quality is ensured.
Description
technical field [0001] The invention relates to the technical field of mechanical components, in particular to a welding auxiliary device for butt jointing of steel pipes with different pipe diameters. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. In the production process, the process of changing the shape, size, position and nature of the production object to make it a finished or semi-finished product is called a process. It is an essential part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines. Other processes are called auxiliary processes...
