Description

one

FIELD OF THE INVENTION The invention relates to the field of welding, especially when rotating t of human cylindrical articles with respect to a horizontal base line.

A device is known which comprises a rotator and roller bearings, each of which is made in the form of a frame pivotally connected to the base, on which the support rollers are mounted and which is spring-loaded relative to the base.

However, in the known device, due to the beating of the cylindrical part of the product, irrelevant radial forces arise between the product and roller bearings.

The purpose of the invention is to compensate for radial forces during rotation of the product.

This is achieved by the fact that the axis of the ball is located symmetrically relative to the support rollers, and the springs are located on both sides of the axis of the hinge, and a vertical groove is made in the frame along the axis of the hinge of the frame, which allows the frame to move in the vertical direction.

FIG. 1 shows the proposed device, a general view; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 is the same, view B in FIG. 2; in fig. 4 is the same, section B-B in FIG. 2

The proposed device includes a rotator 1 with a flat-2, a tailstock 3 and

roller 4, based on the frame 5.

Roller supports are non-driven rollers 6 mounted on axles 7, rigidly fixed in brackets 8, which are provided with bottom bottom dove-tail guides 9 connected to frame 10, which is equipped with brackets 11, through which holes the studs 12 with spherical supports 13 are passed and adjusting

gayas.

The lower legs of the pins 12 rest on the springs 14 and are passed through the holes of the base and 15 of the trolley 16.

In the middle part of the frame 10 there is a vertical groove a, covering the axis 17, which is located symmetrically with respect to the support rollers and fixed in brackets 18 mounted on the base 15 of the trolley 16. The device operates as follows.

Roller supports are installed on a certain diameter, the welded 1 piece is fixed and laid on them, the plant has its left end into the flange 2 rotator /. Then move the cart 16 with the tailstock 3 to

stop with the right end of the product. After fixing the carriage by rotating the tailstock flywheel, they fix the product.

In the process of clamping the product under external forces from the side of the product, the rollers 6

roller 4 is somewhat lowered along with

frame 10, slightly squeezing 14. In this case, the rollers 6 with the frame W retain the possibility of moving in the vertical direction along the axis 17 and rocking around it. When a product with radial beats is rotated, the roller bearings 4 have the ability to reciprocate in the vertical direction due to the springs 14 and the possibility of oscillation about the axis 17, which compensates for the resulting radial forces.

The subject of the invention is a device for rotating articles, preferably cylindrical, with horizontal, horizontal axis, containing a rotator and roller supports, each of which is made in the form of a hinge-connected frame, on which the support rollers are mounted and which is roughened relative to the base, characterized by the fact that, in order to compensate for radial forces, the hinge axis is arranged symmetrically relative to the support rollers, and the springs are located on both sides of the hinge axis, moreover, in the frame, along the axis of the hinge a vertical groove is made, allowing the frame to move in a vertical direction.
