Abstract

The invention provides a portable miniature energy-storing spot welding machine. The portable miniature energy-storing spot welding machine comprises a nickel-metal hydride battery pack (1) equipped with a charger, a spot welding control circuit module (2), an energy-storing charging switch (3), a Farad-level energy-storing capacitor (4), a spot welding discharging switch (5), a spot welding gun (6) provided with a manual control switch, a grounding clamp (7) connected with the welding machine through a cable, and an energy regulation and display panel (8), wherein the nickel-metal hydride battery pack (1), the spot welding control circuit module (2) and the energy-storing charging switch (3) are connected mutually, the spot welding control circuit module (2) is further connected with the spot welding discharging switch (5), the spot welding gun (6), the grounding clamp (7) and the energy regulation and display panel (8), the energy-storing charging switch (3) is connected with the Farad-level energy-storing capacitor (4), the Farad-level energy-storing capacitor (4) is connected with the spot welding control circuit module (2), the energy-storing charging switch (3), the spot welding discharging switch (5) and the energy regulation and display panel (8), the spot welding discharging switch (5) is connected with the spot welding gun (6), the spot welding gun (6) is connected with the energy regulation and display panel (8), and the grounding clamp (7) is connected with the energy regulation and display panel (8). The portable miniature energy-storing spot welding machine is designed for welding thin / ultra-thin steel plates or delicate and miniature parts, and can be used for solving the problem of fast on-site installation of some sensors.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to a portable miniature energy storage spot welding machine. Background technique [0002] Spot welding connection is a commonly used connection relationship between metal materials at present, and the usual spot welding operations are welded by spot welding machines. [0003] At present, in the safety monitoring system of large-scale engineering facilities such as railways, bridges and electric power, the installation of sensors is the key technology for obtaining monitoring signals. For example, stress sensors and shunt current sensors are generally fixed by bonding, riveting or bolts, the construction process is complicated, and sometimes it will cause damage to the measured point. And the installation equipment is not easy to carry, which limits the promotion in some fields. [0004] The known spot welding technology is the basic principle of instantaneous he...

Problems solved by technology

Low power efficiency, bulky equipment and inconvenient to carry

Even if it can weld thin and light parts, the current regulation is not precise enough to meet the requirements of portable hand-held spot welding conditions such as the sensor installation above.
