Embodiment 1

[0030] Embodiment 1 Fig. 1 shows the step block diagram of the preparation of the first short-circuit ring and its welding and fixing method, and the specific steps are as follows:

[0031] Plate selection: choose copper plate with relatively low resistivity as the short-circuit ring material. The thickness of the copper plate is 8 mm, which is a rectangular plate. The two side edges 5 of the plate are used as the butt end faces, and the shape is a V-shaped cross-sectional groove, as shown in Figure 3 shown.

[0032] Opening of through holes: Drill holes on the copper plate. The through holes are tapered holes with a maximum inner diameter of about 50mm. The through holes are evenly arranged and distributed along the middle of the plate. For the magnetic core cleaning of plates, welding wires and vibrating tables, the cathode cleaning method is used to remove the oxide film on the surface of the short-circuit ring and the welding wire, to prevent the generation of bubbles and ...

Embodiment 2

[0035] Embodiment 2 Fig. 3 shows the block diagram of the steps of the preparation of the second short-circuit ring and its welding and fixing method, and the specific steps are as follows:

[0036] Plate selection: choose a copper plate with a relatively low resistivity as the short-circuit ring material. The thickness of the copper plate is 3mm. It is a rectangular plate, and the two side edges of the plate are used as the butt end faces.

[0037] Opening of through holes: Drill holes on the copper plate. The through holes are tapered holes with a maximum inner diameter of about 50mm. The through holes are evenly arranged and distributed along the middle of the plate. For the magnetic core cleaning of plates, welding wires and vibrating tables, the cathodic cleaning method is used to remove the oxide film on the surface of the short-circuit ring and welding wire, to prevent bubbles and slag during welding, and to remove the grease, coating and processing on the surface of the...

Abstract

The present invention relates to a welding-fixing method of a short circuit ring and an adopted short circuit ring. A plank stuff is provided with a through hole, the plank stuff is curled to form a cylinder, and then gas shielded welding is used at the through hole position, the abutting edges after the plank stuff is curled, and the upper edge and the lower edge of the cylinder to weld the cylinder on a fixing surface. The short circuit ring is in the curled plank stuff shape, the plank stuff with the short circuit ring is provided with the through hole used for gas shielded welding. After the short circuit ring adopted by the short circuit ring welding fixing method is fixed, the welding spots are distributed reasonably, the service life is greatly prolonged, without easy loosening, and the manufacture cost is low in the severe and the ultra high frequency mechanical experiment environments; the structure of the short circuit ring adopted by the method is simple, the rationality of the welding fixing spots of the short circuit ring can be effectively ensured, the gap between the short circuit ring and the fixing surface is eliminated, a vibration test is not disturbed by the infirm fixing of the short circuit ring, the short circuit ring has firm structure, the service life of the short circuit ring is prolonged, and correspondingly, the service life and the safety coefficient of a vibrating platform are also improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary accessories of an electrodynamic vibration test device, and in particular relates to a method for welding and fixing a short-circuit ring of an electro-dynamic vibration test device, and a short-circuit ring used in the short-circuit ring welding method.
