Positioner for automatic welding of flanges

Abstract

This utility model provides an automatic flange welding positioner, including a base frame, a rotating component, a fixed component, and a tilting component. The rotating component is installed inside the base frame, and fixed components are installed at both ends of the rotating component. The flange to be welded is installed on the rotating end of the rotating component, which drives the flange to rotate axially. One end of each fixed component is fixedly installed on a tilting component, and the tilting component is rotatably connected to the base frame. The tilting component drives the rotating component to tilt. By setting up the rotating component and the tilting component, the traditional manual tilting or single-axis machine tilting flange welding method is replaced. The rotating component and the tilting component can quickly switch to the side welding or flat welding posture according to different flange welding requirements. Compared with the traditional single-axis positioner or manual tilting welding method, it reduces manpower waste and improves work efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and in particular relates to a positioner for automatic flange welding. Background Technology

[0002] In industrial production, flanges are critical connecting components for pipelines, pressure vessels, and complete sets of equipment. Their welding quality directly affects the system's sealing performance, pressure resistance, and operational safety. In fields such as petrochemicals, nuclear power, aerospace, and shipbuilding, flanges are often exposed to extreme environments such as high pressure, high temperature, and corrosive media. Defects in the welding, such as porosity, lack of fusion, and cracks, can lead to major safety accidents such as media leakage and equipment explosions. Traditional flange welding often employs manual welding or simple tooling-assisted welding methods, resulting in poor quality stability, low production efficiency, waste of human and material resources, and potential production safety hazards.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, the automatic flange welding positioner includes a base frame 1, a rotating assembly 2, a fixed assembly 3, and a tilting assembly 4. The rotating assembly 2 is installed inside the base frame 1, and fixed assemblies 3 are installed at both ends of the rotating assembly 2. The flange to be welded is installed on the rotating end of the rotating assembly 2. The rotating assembly 2 is used to drive the flange to rotate axially. One end of each fixed assembly 3 is fixedly installed on a tilting assembly 4, and the tilting assembly 4 is rotatably connected to the base frame 1. The tilting assembly 4 is used to drive the rotating assembly 2 to tilt. The tilting assembly 4 can adjust the posture of the flange. Flat welding or side welding can be selected according to different flange welding requirements, reducing manual handling and tilting, reducing labor and improving work efficiency.

[0033] like Figure 2 As shown, the base frame 1 includes two support frames 11, which are parallel to each other and facing each other. Each support frame 11 has multiple first positioning screw holes 111 at its lower end, and each first positioning screw hole 111 is internally threaded with a positioning bolt.

The inner ring of the housing 23 is rotatably connected to the outer periphery of the first turntable 21 via the roller assembly 24. The drive unit 22 is located at the lower end of the housing 23. The drive unit 22 drives the first turntable 21 to rotate relative to the housing 23. The rotating unit 21 can adjust the position of the weld seam by rotating via the drive unit 22, reducing manual adjustment, labor, and improving work efficiency. Multiple second positioning screw holes 211 are evenly distributed on the first turntable 21 for connecting external chucks.

The step 212 is located between the shell surface 231 and the lower shell surface 233. Multiple roller groups 24 are respectively rotatably arranged at the lower end of the upper shell surface 231 and the upper end of the lower shell surface 233 in the circumferential direction. The outer periphery of each roller group 24 is rotatably connected to the step 212. The roller groups 24 are set to assist the rotation of the first turntable 21, reduce the frictional resistance generated between the first turntable 21 and the outer shell 23 when rotating, improve the stability of equipment operation, improve the flange welding quality, and improve work efficiency.

[0037] like Figure 7As shown, the fixing component 3 includes a left fixing unit 31 and a right fixing unit 32.

The other end of the mounting plate 312 is fixedly connected to one side of the outer shell 23. By setting the fixing component 3, the outer shell 23 is fixedly mounted on the reversing component 4, so that the reversing component 4 can drive the outer shell 23 to rotate, thereby driving the first turntable 21 to rotate. Furthermore, the chuck connected to the first turntable 21 rotates, reducing manual rotation, reducing manual labor, and improving work efficiency.

[0038] like Figure 7-8 As shown, the flipping assembly 4 includes a left flipping unit 41 and a right flipping unit 42. The left flipping unit 41 and the right flipping unit 42 have the same structure and are arranged opposite each other. The left flipping unit 41 includes a flipping motor 411, a second gear 412, a third gear 413, a second turntable 414, and a second bearing box 415. The flipping motor 411 is fixedly installed inside the support frame 11 and is located on one side of the inspection door 112. The flipping motor 411 is prior art, model YE4-H63-355. The output shaft of the flipping motor 411 is fixedly installed with the second gear 412, and the outer surface of the second gear 412... The third gear 413 is meshed around the periphery of the third gear 413. One side of the third gear 413 is fixedly connected to one side of the second turntable 414. The second gear 412 and the second turntable 414 form a synchronous rotation structure through the third gear 413. A positioning protrusion 4141 is provided on one side of the second turntable 414. The periphery of the positioning protrusion 4141 is fixedly sleeved on the inner ring of the second bearing box 415. The periphery of the second bearing box 415 is fixedly installed on the support frame 11. The flipping component 4 can adjust the posture of the flange according to the flange welding requirements, reduce manual flange flipping welding, reduce manual labor, and improve work efficiency.

[0039] Working process of a positioner for automatic flange welding:

[0040] First, the equipment is fixed to the production line through the first positioning screw hole 111 and positioning bolt at the lower end of the support frame 11 in the base frame 1. The flange workpiece is fixed by the chuck connected to the second positioning screw hole 211 on the first turntable 21. Then, when the rotating assembly 2 is in operation, the rotation motor 221 of the drive unit 22 drives the first gear 222 to rotate. Since the first gear 222 meshes with the gear teeth 213 on the periphery of the first turntable 21, it drives the first turntable 21 to rotate in the outer shell 23. The roller group 24 in the outer shell 23 cooperates to ensure smooth rotation, thereby driving the flange to rotate axially. At the same time, when the flipping assembly 4 is working, the flipping motors 411 of the left flipping unit 41 and the right flipping unit 42 drive the second gear 412 to rotate. The second gear 412 meshes with the third gear 413, causing the third gear 413 to drive the second turntable 414 to rotate. The second bearing box 415 ensures its stable rotation. The rotating assembly 2 and the flange are flipped by the fixing assembly 3 to adjust to a suitable welding posture.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
