Description

FIG.

31

The invention relates to welding production, in particular, to devices for fixing blanks during welding and brazing of compact shells.

The aim of the invention is to expand the technological capabilities of the device by using it for welding longitudinal seams of shells with edge flanging.

Figure 1 shows the proposed device, a general view; FIGS. 2 and 3 section A-A in FIGS. 1 for the shells of various shapes; FIGS. 5 and 6 show various types of the replaceable element

The fixture contains a rack 1 mounted on the base, in which the console is installed parallel: pressure 2 and support 3 having the ability to adjust their movement.

On the pressing console 2, screws with a radial groove are evenly mounted in the lower part, and the console 2 is secured against movement in the rack 1 by screws 5 and 6,

Between consoles 2 and 3 there are clamps 7 with end grooves for the flanged sides of the shell, which are fixed to screws having an end conical section 8 supported in a conical boring in clamp 7. The latter is suspended on the screw h by means of a pin 9 which enters into its radial groove .

The support console 3 is made replaceable for shells of various shapes and different types of longitudinal seams, such as round, square, multi-faceted, with an axial groove for internal edge sampling, etc.

The clamp 7 may have a different shape of the end grooves depending on the type of weld.

The device works as follows.

The rack 1 is secured to the workbench or in a vice,

Consoles 2 and 3 of the required shape are installed in the holes of the rack 1 and fixed with screws 5 and 6. The extension of the consoles is selected depending on the required size of the weld,

The screws are turned out.

Then, the necessary clamps 7 are mounted on the screws k and fixed with pins 9 with the possibility of free rotation about the axis of the screws k in mutually perpendicular planes

The shell prepared for welding is inserted between the support and pressure brackets 2 and 3, and the reduced edges are pressed by the presses 7 to the console 3 with the appropriate number of screws,

When docking the flanged edges, the last ones are inserted into the groove 10 4Q in the clamps 7, and the edges which are flanged inside the shell are inserted into the similar groove in the support console 3.

After tightening the screws k, the position for welding is fixed, while the alignment of the position of the clamp 7 with the direction of the edges being welded is ensured by the floating position of the clamps 7.

In the process of welding or soldering, the clamps 7 simultaneously play the role of screens that protect against spatter and sparks.

When the size of the welded shell is changed, the support bracket 3 is replaced with an appropriate shape,
