[0031] Specific implementation mode one: combine Figure 1-Figure 3 Describe this embodiment, an adjustable butt joint positioning device for different-diameter pipes in this embodiment, including an adjustable bending plate 1, a short fixed angle steel 2, a long fixed angle steel 3, a first pressing mechanism 4, a second pressing mechanism 9, The first support arm 10 and the second support arm 11, one end of the adjustable bent plate 1 is connected with the long fixed angle steel 3, the other end of the adjusted bent plate 1 is connected with the short fixed angle steel 2, and the first pressing mechanism 4 is inserted into the first In the first threaded hole 101 of the support arm 10, the first mounting arm 10 is fixedly installed on one end of the adjustment bent plate 1, and the second pressing mechanism 9 is inserted into the second threaded hole 111 of the second support arm 11, and the second support arm 11 is fixedly installed on the other end of the adjustable bent p...

specific Embodiment approach 2

[0032] Specific implementation mode two: combination Figure 1-Figure 3 Describe this embodiment, an adjustable butt joint positioning device for different-diameter pipes in this embodiment, the bottom of the long fixed angle steel 3 is connected to the first rib 6, the bottom of the short fixed angle 2 is connected to the second rib 13, and the bottom of the fixed angle 2 is connected to the second rib 13. The first rib 6 and the second rib 13 are used to increase the rigidity of the long fixed angle 3 and the short fixed angle 2, avoiding the deformation of the long fixed angle 3 and the short fixed angle 2 due to the heavy steel pipe, which affects the welding accuracy of the steel pipe.

Abstract

The invention discloses an adjustable reducing pipe butt joint positioning device and a using method thereof, and belongs to the field of boiler manufacturing. The problems that the machining precision is low and the production efficiency is low when a steel pipe is welded at present are solved. The device comprises an adjusting bent plate, short fixing angle steel, long fixing angle steel, a first pressing mechanism, a second pressing mechanism, a first supporting arm and a second supporting arm; one end of the adjusting bent plate is connected with the long fixing angle steel, the other endof the adjusting bent plate is connected with the short fixing angle steel, the first pressing mechanism is inserted into a first threaded hole of the first supporting arm, a first mounting arm is fixedly mounted at one end of the adjusting bent plate, the second pressing mechanism is inserted into a second threaded hole of the second supporting arm, and the second supporting arm is fixedly mounted at the other end of the adjusting bent plate. The reducing pipe butt joint positioning device is simple in structure and convenient to disassemble and assemble, the using method is concise in step,a large amount of manpower is saved, and the machining efficiency and the machining precision are improved.

Description

technical field [0001] The invention relates to an adjustable butt joint positioning device for different-diameter pipes and a use method thereof, which belong to the field of boiler manufacturing. Background technique [0002] In the process of manufacturing boiler products, it is necessary to weld and assemble the steel pipes. Due to the diversity of products and the different requirements for the performance of the heating surface, there are differences in the grooves, inner bore sizes and wall thicknesses of the butt steel pipes on both sides. For When welding steel pipes with different thicknesses, it is necessary to ensure that the inner walls are flush, and the amount of misalignment of the inner walls does not exceed 10% of the wall thickness. Add gaskets under the steel pipe on the lower side of the center line to adjust the height of the steel pipe. This method has the following defects: [0003] 1. Due to the fixed thickness of the gasket, it cannot meet the accu...
