Automatic electric resistance welding equipment for hoop spring hook

Abstract

The invention relates to a basket spring hook automatic electric welding device which comprises a feeding device, an electric welding machine, a basket exchange rotation compression device fixed on the support and formed by a rotation lifting device, an air-powered compression device, a servo-rotation device and an air-powered supporting device, and a control board. The basket is arrange don the dual-position clamping-material station of said rotation lifting device; the spring hook via vibration automation discharging and high-pressure air nozzle is blown to the air-powered clamp and absorbed by another air-powered clamp to be transferred to the basket welding position; two electrodes of said electric resistance welding machine will clamp two work-pieces to weld a spring hook via electric loop, then said two electrodes are reset; and the servo-rotation device can rotate the basket for 30 degrees to repeat aforementioned steps until welding 12 spring hooks on the basket. The inventive device has the advantages of lower technique demand; continuous operation; improved efficiency; quick operation of air-powder clamp; accurate welding positioning; improved product quality; and smooth welded appearance.

Description

technical field [0001] The invention relates to a resistance welding equipment, in particular to a special equipment for welding multiple spring hooks with complex shapes on the same part basket ring spring hook automatic resistance welding equipment. Background technique [0002] At present, there are many kinds of resistance welding equipment, but many welding workpieces are still manually operated. For example, the 12 spring hooks used for hanging basketball nets on the basketball hoop are all manually operated by each spring hook. Machine welding is fixed on the welded circular ring. Because the shape of the spring hook is complex and difficult to place, it takes a long time to weld a single piece. In addition, the spring hook also has requirements for positioning welding, size, appearance quality, and beautiful finish. People with certain skills and experience are required to operate, and the quality is difficult to control. [0003] Patent No. 200520018901.X "A Ball C...
