Abstract

The invention discloses a special multiple-spot spot welding machine for an oil baffle plate. The special multiple-spot spot welding machine comprises a machine frame, a machine case, a welding device and a working table, wherein the machine case is arranged on the machine frame, a transformer is arranged in the machine case, and the longitudinal positions of the welding device and the working table are correspondingly arranged on the machine frame. The welding device comprises a lifting mechanism and an electrode arm, wherein the lifting mechanism can drive the electrode arm to longitudinally move, and a plurality of electrode heads are arranged at the lower end of the electrode arm. A positioning frame and a lower electrode plate are arranged on the working table, wherein the positioning frame is arranged on the lower electrode plate, and the lower electrode plate is connected with the transformer. The transformer is connected with a power supply and comprises three one-way transformers, the secondary of each one-way transformer is connected with a silicon diode, and the three one-way transformers and the silicon diodes form a three-phase full wave rectifier circuit. The three-phase full wave rectifier circuit forms a secondary direct-current power supply, and inductive reactance and the influence of the inductive reactance to current are eliminated, so that welding current is stable and consistent, welding positions are even in heating, surface shaping is attractive, welding points are firm, and energy is saved.

Description

technical field [0001] The invention relates to a spot welding machine, in particular to a special multi-point spot welding machine for oil baffles. Background technique [0002] In the past, single AC spot welding machines were mostly used for oil baffles, but the welding efficiency was low due to the large number of welding spots, and it was prone to inconsistent welding effects or even false welding and missing welding, resulting in very unstable product performance. At the same time, its welding appearance is unsatisfactory and cannot meet customer requirements. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a special machine for multi-spot welding of oil baffles. Splash phenomenon, easy to use. [0004] The technical solution adopted by the present invention to solve the technical problem is: a special machine for multi-point spot welding of oil baffle plate, including frame, case, welding device a...
