Abstract

The invention provides resistance welding equipment and a welding control method. The resistance welding equipment consists of a frame, an electric cabinet and a PLC system, a welding transformer, an action mechanism, a welder controller, a waste box, an optical fiber sensor and a sensor controller, wherein the action mechanism consists of a baseplate, a main frame, a vertical cylinder, a main linear guide rail, a linear guide rail, a positioning manual press claw, a positioning fixture, a linear bearing, a main linear bearing, a positioning nut, an adjusting pressure spring, a screw mandrel, a servomotor, a coupler, a displacement sensor, a clamping cylinder, a pressure sensor, a left electrode, a right electrode, left and right linear guide rails, left and right linear bearings, an auxiliary frame, a connecting rod and a clamping pressing plate. The pressure sensor and a tracking system are adopted to collect pressure signals, the displacement sensor and the tracking system are adopted to collect displacement signals, and a PLC operational program is adopted for control, so that the welding of metal workpieces adopts dynamic on-line control to comprehensively monitor various welding control points in the whole process, and the welding deformation is controlled between 0.01 and 0.45mm to ensure welding quality.

Description

technical field [0001] The invention relates to welding equipment, in particular to a resistance welding equipment and welding control method for welding small metal objects. Background technique [0002] The existing manual or pneumatically driven resistance welding equipment for welding small metal objects generally controls the welding effect by controlling the welding current and welding time. Since the welding displacement and welding pressure are not kept constant, real-time monitoring cannot be performed at the same time. As a result, there are large quality fluctuations in the welding process, which affects the welding quality of the product. Therefore, the welding performance of the resistance welding equipment for small metal objects still needs to be further improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision pressure sensor and tracking system to collect pressure signals and hi...
