The contact A is separated from the contact B when the press button (2) is in a released state, so that the switch module is switched to a closed state to further turn on the LED (3); the contact A is connected with the contact B when the press button (2) is in a pressed state, so that the switch module is switched into an opened state to further turn off the LED (3). The invention further provides a corresponding welding machine with the lighting device. The lighting device of the gas shielded welding machine uses a door sheet of on the side of a wire feeder of the gas shielded welding machine to achieve automatic turning on and off of the light, thereby facilitating wire replacement and being affordable.
Description
Technical field
The present invention relates to welding machine, the especially illumination of gas shielded welding machine wire feed system, particularly, relates to lighting device and the welding machine thereof of gas shielded welding machine.
Background technology
At present; gas shield is welded on industry and family expenses more and more; the inside of the wire feed system of general domestic gas protection weldering in machine; because the diameter of domestic gas protection welding wire is all smaller; substantially below 1mm; and the diameter of the wire convey soft pipe of wire-feed motor is also smaller; wire-feed motor is contained in again the inside of welding machine; in the situation that light is bad; be difficult to welding wire to pierce into the wire convey soft pipe of wire-feed motor; and easily dislocation between welding wire and the wire feed rolls of wire-feed motor, changes wire tray while causing welding machine to use more difficult, and even welding machine can not be worked normally.
Summary of the invention
For defect of the prior art, the object of this invention is to provide a kind of lighting device and welding machine thereof of gas shielded welding machine.
Lighting device according to gas shielded welding machine provided by the invention, comprising: button 2, LED3, switch module;
Described switch module is connected in the current supply circuit of LED3; Button 2 comprises contact A and contact B;
When button 2 is during in releasing orientation, contact A and contact B are separated, and make switch module switch to closure state, and then light LED3;
When button 2 is during in down state, contact A is connected with contact B, makes switch module switch to open mode, and then extinguishes LED3.
Preferably, described switch module comprises: the first resistance R 52, the second resistance R 53, the 3rd resistance R 54, triode Q7; Wherein, the colelctor electrode of triode Q7 is connected to power supply positive pole by LED and the first resistance R 52, the grounded emitter of triode Q7, the base stage of triode Q7 connects one end of the 3rd resistance R 54, and the other end of the 3rd resistance R 54 is connecting terminal A and be connected to power supply positive pole by the second resistance R 53 respectively; Contact B ground connection.
According to the welding machine with lighting device provided by the invention, the lighting device that comprises above-mentioned gas shielded welding machine, wherein, the side door plate 1 of described welding machine shell comprises top panel part and the side panel part being connected, and described button 2 is positioned at described below of determining faceplate part; Described side door plate 1 can freely rotate between closed position and open position;
When described side door plate 1 is positioned at described closed position, described top panel is partly tight against described button 2 and makes described button 2 in down state, to extinguish LED;
When described side door plate 1 is positioned at described open position, described top panel part is separated with described button 2, makes described button 2 in releasing orientation, to light LED.
Preferably, described LED is positioned at the side top of the wire-feed motor of welding machine.
Compared with prior art, the present invention has following beneficial effect:
The present invention utilizes the door-plate of gas shielded welding machine wire-feed motor one side realize the automatic unlatching of illuminating lamp and extinguish, thereby the present invention can conveniently change silk, economic and practical.
Accompanying drawing explanation
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present invention will become:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are structural representations of the present invention;
Fig. 5 is circuit theory diagrams of the present invention.
In figure:
1 is side door plate;
2 is button;
3 is LED.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art further to understand the present invention, but not limit in any form the present invention.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention.
Following according to Fig. 1～Fig. 5, illustrate better embodiment of the present invention:
As shown in Figure 1, welding machine front panel is lower than upper casing, load onto in the above button 2, in the situation that the door-plate 1 of side is opened, the height of button 2 is higher than upper casing, at this moment two contacts on button 2 are in off-state, two contacts on button 2 are connected in respectively 3 pin and 4 pin of J8 on front panel circuit board, at this moment triode Q7 conducting, and LED is arranged on the upper right side of wire-feed motor, the anode of LED is connected on 1 pin of J8, the negative electrode of LED is connected on 2 pin of J8, and in the time of Q7 conducting, LED inside has electric current to pass through, LED is shinny, throws light on to the cabinet of side.
When the door-plate 1 of wire-feed motor side puts down, as Fig. 4, door-plate is pressed button 2, at this moment two contact adhesives of button 2 inside, because one of them contact is connected on electronegative potential, pin earthing potential of resistance R 53 and R54 at this moment, not conducting of triode Q7, LED does not work, and when assurance welding machine normally uses, LED is in extinguishing state.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present invention.
