The invention relates to a spot welding process and a special fixture thereof for a switch lug plate. The process comprises the steps for constituting a weldment by the lug plate and a conducting wire or a conducting strip as follows: a spot welder provided with an upper electrode and a lower electrode is adopted; a fixture is arranged between the upper electrode and the lower electrode, an upperelectrode part is hinged with an lower electrode part and further forms the fixture, and the insulated upper electrode part and the lower electrode part are insulated and opened with certain degrees;the weldment is inserted between the upper electrode part and the lower electrode part of the fixture, the lower electrode is fixed at the lower electrode part of the fixture, the upper electrode is pressed down for allowing the upper electrode part to be communicated with the upper electrode, and the spot welder can discharge when the upper electrode part, the weldment and the lower electrode part are compressed, so that the weld of the weldment can be finished; then the upper electrode is raised, and the upper electrode part and the lower electrode part are recovered to the separated state.The spot welding process for a switch lug plate efficiently solves the difficult problem of performing spot weld in narrow space and greatly improves the production efficiency.
Description
(1) Technical field [0001] The invention relates to a spot welding process and a special fixture for switch lugs. (2) Background technology [0002] After the weldment is combined, the pressure is applied through the electrode, and the method of welding with the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area is called resistance welding (also known as spot welding). Resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in various industrial sectors such as aviation, aerospace, energy, electronics, automobiles, and light industry. It is one of the important welding processes. [0003] An existing electric socket includes a switch, a conductive sheet and a wire, and usually it is necessary to weld the lug of the switch to the wire or the conductive sheet. Because spot welding has the advantages of energy saving and e...
