The utility model relates to devices for the manufacture of useful products and can be used in machine building to install: and fasten products for syarks, with centering up to / inside 5 surfaces .- /. Self-propelled internal centralizer for assembling and welding of pronged pipe joints and other two products is known. The centralizer contains a centered part, consisting of two rows of individual drives with individual drives for each row, which is more complicated. it removes the design and increases the dimensions of the TOI® center (a, p. 1632720 V23K37 / b53): - -, Also known for assembling for welding ring seams, have expandable elements in the form of two pairs of disks inclined to the axis of the centralizer and bent in pairs in an arc. ,., -. . . each other with petals, making b4sh FROM alloys with the effect of super-elasticity (a, p.1715538) ... The disadvantage of this device is the difficulty in manufacturing REMAINABLE elements and the impossibility of centering products consisting of two parts that differ in size from each other. and fordby internal surfaces (if the surfaces differ pyr from each other. even the sizes within the tolerance for the manufacture of these parts),. The proposed utility model is simple in design and can reduce the range of technological ocHacfivki, when assembling for welding parts of products, I have the same. ,,. , .-. . 2 ..,, (for example: cone and cylinder, square and cylindrical, square and cone, etc.), while ensuring accuracy within the range of 1–3, 3 mm, this is achieved with a diameter of 12 or 13 fixing. a part of the product 20 with smaller dimensions does not interfere with the further movement of the two-arm levers II and the strips with the fixing brackets: ele- ments 14 to the stop of the latter in the product that has large dimensions of the inner surface (21), and due to the possibility of the hoses 12., and 13 to swing on its o-axes - turning paracholno centered on top of the bridge, the device allows you to collect products not only with internal surfaces that are sewing parallel generators, but also products in which the surfaces are centered, have generators in the form of cones, pyramids, etc. The essence of the utility model is illustrated by the drawings, where w | ig. |, Shows the centralizer for products consisting of two hours at which the surfaces differ from each other.

In order to prepare for the operation of the centrate, the fixing elements 14 and 15 are set according to the control element so that the strips 12 g 13 become parallel to the internal surfaces that make up the parts (20,21),

The centralizer-works as follows in the assembly to be assembled for welding, the centralizer is installed so that the joint of its two parts between the strips 12 and 13, By turning the screw 5 we move the nuts b and 7 towards each other, while the levers 8 move radially the levers.
