Automatic spot welding device for filter inner net

Abstract

The invention discloses an automatic point welding device for a filter inner screen. The automatic point welding device comprises a rack. A positioning mold used for fixing the inner screen is installed on the rack. The rear end of the positioning mold is connected with a push air cylinder. A pair of positioning air cylinders, located on the left side and the right side of the positioning mold respectively, is installed on the outer sides of the rack. Positioning clamping plates are installed on the positioning air cylinders and provided with inner cambered surface structures matched with the outer wall of the inner screen in shape. An electrode mold is installed at the outer end of the positioning mold. A circle of point welders are arranged in the peripheral direction of the electrode mold at intervals. The point welders are installed on corresponding point welding air cylinders. The point welding air cylinders are installed on the outer side of the rack. The point welders are connected with red copper rows which are connected with a transformer. According to the automatic point welding device for the filter inner screen, the inner screen is installed on the positioning mold, fixed through the positioning plates and then subjected to point welding through the circle of point welders, so that welding of the inner screen is completed at a time, operation is simple and convenient, and the work efficiency is high. In addition, the positioning air cylinders and the point welders are adjustable so that the automatic point welding device can be suitable for inner screens with different sizes, and wide popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of filter processing, in particular to an automatic spot welding device for a filter inner net. Background technique [0002] At present, when processing the inner mesh of the filter, a row of inner rings need to be placed inside the inner mesh, and the inner rings are welded to the inner mesh. The existing technology uses manual welding, or manual welding after positioning with auxiliary equipment, so that It is very difficult to align the seam, and the welding quality is difficult to guarantee. Moreover, under long-term operation, the operator is prone to fatigue and the efficiency is low. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems existing in the prior art, and provides an automatic spot welding device for the inner net of a filter, which is easy to operate, automatically performs spot welding on the inner net, and has high working efficiency. ...
