Description

The invention relates to welding, in particular to devices for assembly for welding, and can be used to center the shaft with a flange.

The purpose of the invention is the expansion of technological capabilities by ensuring accurate centering of the shaft with the flange.

The drawing shows the proposed device, General view.

The device contains mounted on the base 1 in the form of a prism 2 lodgement to accommodate the shaft 3, the housing 4, in which the glass 5 is mounted with the possibility of rotation in the bearings 6. In the glass 5 is placed coaxially with it pin 7, containing expanding cams 8 for the flange 9, and pins 7 - coaxial pusher 10 and conical sleeve 1.1 for expanding cams 8. In the Central hole of the sleeve 11 is mounted with relative movement of the conical center 12, which also has a Central axial hole, which also with the possibility of relative The screw installed by its head is screw 13 screwed into the pusher 10. The movement of the screw head 13 relative to the center 12 is limited by a washer 14 fixed in the center 12 by the locking ring 15. The cavity 16 in the pinole 7 between the ends of the center 12, the conical sleeve 11 and the pusher 10 is filled with working fluid . A restrictive circlip 17 is installed on the outer surface of the center 12. The device is equipped with a drive 18 in the form of a power cylinder, the rod 19 of which is connected to the pusher 10, and the pin 7 is connected with an annular protrusion 20 and a spring 21 acting on the pusher 10.

The device operates as follows.

By applying pressure to the rod cavity of the actuator drive cylinder 18, the device is initialized. A shaft 3 having center holes at both ends is mounted with an end that is welded to the flange onto a prism 2 and the other at the center (conical) of the rotation drive (not shown). The flange 9 is mounted on the pins 7. Pressure is applied to the right rodless cavity of the actuator actuator cylinder 18, the rod 19 moves the pusher 10 and to the left through the spring 21 the pin 7. Kinol 7 protrusion 20 compresses the flange 9 to the shaft 3 and stops. The pusher 10, compressing the spring 21, continues to move to the left, compresses the fluid located in the cavity 16.

Under pressure, the center 12 and the sleeve 11 move to the left. The center 12 enters the center hole of the shaft 3, centers it, lifting it above the prism 2, and clamps it in the centers. The conical sleeve 11 acts on the cams 8, the latter, leaving the pinole 7, center the flange 9. After centering, the shaft end located in the rotation drive is clamped, the rotation drive of the shaft 3 and flange 9 is turned on and the joint is welded. To expand the welded shaft 3 and flange 9, pressure is applied to the left cavity of the actuator power cylinder 18. The pusher 10 and the screw TK are moved to the right, a vacuum is created in the cavity 16 and forces arise that tend to move the center 12 and the sleeve 11 to the right. But since these efforts to divert the center 12 and the sleeve 11 may not be enough, to increase the reliability of the device, the center 12 is provided with a screw head 13 acting on the washer 14, and then the retainer retaining ring 17 is withdrawn. 11. When the center 12 and the sleeve 11 are withdrawn in the described sequence, the pin 7 is stationary due to the compressed spring 21. After releasing the shaft 3 from the action of the center 12 and the flange 9 from the action of the cams 8, the pin 7 moves to the right until it stops with an annular protrusion 20 into the end of the glass 5. Welded product removed, the device is prepared for loading the shaft 3 and the flange 9.

Using the proposed device due to the provision of separate alignment of the shaft and flange can improve the accuracy of centering, the quality of welding and welded products.
