Abstract

The invention relates to welding, in particular to ancillary equipment for fixing products, and can be used for assembling pipes with flanges for welding. The purpose of the invention is the expansion of technological capabilities by ensuring that one of the flanges is accurately installed relative to the pipe end and both flanges are relative to the other. Pipe 2 and flange 3 fixture 1 fixes pipe 2. Flanges 3 are fed to the assembly position, centered with centering elements (CE) 6 and pressed by levers 10 to drive pins 4 and 5. The centered and clamped flanges together with CE6 move in horizontal the direction, with the conical parts centering the tube 2 relative to the flanges 3, after which the flanges are put on the tube. When CE 6 is in contact with the pipe 2, it remains stationary, while the quills 4 and 5, compressing the springs 7, 8, move the flanges 3 along the pipe 2 to a predetermined position. One end of the pipe 2 rests on the splines of the splined sleeve 9 quill 4, and the other end of the pipe is positioned with a gap relative to the splined sleeve 9 quintes 5. After welding, the levers 10 release the flanges 3 and the quiners 4 and 5 to their original position. The design of the device allows the automated assembly of pipe flanges by ensuring accurate positioning of the flanges and the pipe. 1 il.

WITH

The invention relates to a welding technique, in particular, to ancillary equipment for fixing products, and can be used in all fields of mechanical engineering for assembling pipes with flanges for welding,

The purpose of the invention is the expansion of technological capabilities by ensuring that one of the flanges is accurately installed relative to the pipe end and both flanges are relative to the other.

The drawing shows the device, a longitudinal section.

A device for assembling welding pipes with flanges contains an installation device 1 for holding pipe 2 and flanges 3, a unit for centering flanges 3 and pipe 2 and assembling them, consisting of driving pins 4, 5 with conical-cylindrical spline centering elements installed in them 6, spring-loaded springs 7, 8 of different stiffness, made with the possibility of reciprocating movement in the splined sleeves 9 relative to the drive pins 4.5.

Drive pintles 4, 5 are equipped with levers 10 for clamping the centered flanges 3,

The device works as follows.

A fixture 1 is installed on the fixture 1 for holding the pipe 2 and the flanges 3.

2. The flanges 3 are fed to the assembly position, centered by the centering elements b and pressed by the levers 10 to the drive pins 4, 5. After that, the flanges 3 centered on the centering elements 6 and clamped by the levers 10 together with the centering elements 6 are moved in the horizontal direction. Centering elements with 6 tapered parts center pipe 2 relative to flanges

3, the centered flanges 3 are then put on the pipe 2. When the centering element 6 comes into contact with the pipe 2, it remains stationary, and the quintiles 4, 5, compressing the springs 7, 8, move the flanges 3 through the pipe 2 to a predetermined position, with one end pipe 2 rests on the splines of the slotted sleeve of the sleeve 9 quill 4, and the other end of the pipe 2 is positioned with a gap relative to the slotted sleeve 9 of the quill 5.

After welding, the levers 10 release the flanges 3 and the quill spins 4, 5 return to their original position.

Thus, the centering element, unlike the prototype, bases the flanges with its cylindrical surface, and the pipe on the conical surface is pressed with a spring of greater rigidity (spring stiffness 8 quill 5 more than spring stiffness 7 quill 4), which makes it possible to install flanges on the pipe at almost any distance from the end of the pipe.
