Abstract
The invention discloses a welding tongs handle switch detection box and a detection method thereof, belonging to the technical field of welding equipment. The invention is used as a standard component, greatly improves the detection efficiency and reduces the use cost.
Description
Technical Field
The invention relates to the technical field of welding equipment, in particular to a welding tongs handle switch detection box and a detection method thereof.
Background
When the products are delivered from factories, the welding tongs are provided with a three-core cable which is directly connected with a welding tongs handle switch from a power outlet of a welding machine control box (a resistance welding machine can be connected with two welding tongs). The welding process is as follows: after the switch is turned on, the power line transmits signals to the control box, the control box gives electricity to the electromagnetic valve, after compressed air enters the welding tongs cylinder, the upper electrode and the lower electrode of the welding tongs are closed and pressurized, then the control box gives signals to the transformer, and the energizing cable transmits current to the electrodes for welding.
The welding tongs are continuously turned over and swung in use, the handle switch wire is frequently bent in the follow-up process, and the handle switch wire can be broken, so that the welding tongs do not perform welding action after the handle switch presses a button.
The welding tongs typically have two welding specifications (i.e., high current and low current) for welding. While there are three types of handle switch failure, as follows:
1. pressing the button of the welding tongs, the welding tongs do not act (two welding standards), and the failure is caused by the broken wire or the falling off of the wire head at the output end of the handle;
2. pressing the button of the welding tongs, the welding tongs do not act (the first welding standard), and the reason of the fault is that the wire at the input end of the first welding standard of the handle breaks or the wire head drops off
3. Pressing the button of the welding tongs, the welding tongs do not act (the second welding standard), and the wire at the input end of the second welding standard of the handle is broken or the wire head falls off.
Because operators have no operation skills of professional electricians, enterprises cannot equip each operator with a universal meter, the operators have difficulty in judging the fault reasons, and a lot of time is required for eliminating the faults.
Therefore, we propose a welding tongs handle switch detection box and a detection method thereof.
