Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and in particular to a foldable double-panel electric welding machine. Background Technology

[0002] The function of an electric welding machine is to locally heat the joint of a metal workpiece to a molten state by generating a high-temperature electric arc, and usually add filler metal, such as welding rods or welding wires, so that the workpieces are firmly bonded into an inseparable whole after cooling.

[0003] Traditional welding machines typically have a display screen, adjustment knobs, welding interface, and grounding clamp on one end, and a cooling fan, power switch, power cord, and air inlet on the other. During welding, the end with the display screen and adjustment knobs is usually positioned so that it faces the operator. However, in many situations, it's necessary to operate the other end of the welding machine, requiring the operator to frequently walk around to the other side for adjustments, which is very inconvenient, especially in confined spaces or workstations surrounded by workpieces. Furthermore, due to the weight of the welding machine, flipping it over without changing the operator's position also makes it difficult to operate conveniently.

[0004] In addition, welding machines require connecting wires at both the front and rear ends, which are used for welding or for connecting to the power supply. This can easily lead to various wires becoming tangled. While bundling the various wires together can prevent them from becoming tangled, it can cause one or both ends of the wires at the front and rear ends of the welding machine to bend, which can easily lead to fatigue. Therefore, an improvement is proposed. Utility Model Content

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a foldable double-sided welding machine. Please refer to [link / reference]. Figures 1-7 Specifically, during the welding process, the welding machine is usually positioned so that the end with the display screen and adjustment knob faces the operator. However, in many cases, it is necessary to operate the other end of the welding machine. The operator needs to frequently go around to the other side of the welding machine to make adjustments, which is very inconvenient, especially in narrow spaces or workstations surrounded by workpieces. Based on this, a foldable double-panel welding machine is proposed, including a welding machine body 1. The front end of the welding machine body 1 is provided with a display screen 2. The rear end of the welding machine body 1 is installed with a rear frame 3. The rear frame 3 holds a rear control plate 4. A connecting part 5 is provided between the rear control plate 4 and the upper end of the welding machine body 1 for controlling the rear control plate 4 to flip so that the outer end face of the rear control plate 4 faces the same direction as the front end face of the welding machine body 1. The outer end face of the rear control board 4 has a second display screen 41, a power switch 42 and a power cord 43. The second display screen 41, the power switch 42 and the power cord 43 are all connected to the inside of the welding machine body 1 through a wire harness.

[0025] Specifically, the connecting part 5 enables the rear control plate 4 to flip, and the outer end face of the rear control plate 4 to face the same direction as the front end face of the welding machine body 1, both facing the operator's side. The operator can operate on the front end face of the welding machine body 1 and the outer end face of the rear control plate 4 for easy adjustment.

[0026] like Figure 3 The connection part 5 is shown in detail. The connection part 5 includes a blade 51 installed on the upper end of the welding machine body 1. The blade 51 has a protrusion 52 integrally formed on one side facing outward. The rear control plate 4 has a protrusion 54 integrally formed on the side facing the blade 51. The protrusion 52 and the protrusion 54 are spliced ​​together and their axes coincide. A pin 53 passes through the axis of the protrusion 52 and the protrusion 54.

[0027] Specifically, by using the connecting part 5 as a hinge, the rear control plate 4 can be flipped. After flipping, the upper end of the rear control plate 4 can abut against the outer end of the blade 51, so that the rear control plate 4 is in a vertical state and ensures stability.

[0028] like Figure 3 As shown, a magnetic block 55 is embedded in the upper end of the rear control plate 4, and the blade 51 is a metal that can be magnetically attracted. When the rear control plate 4 is flipped, the magnetic block 55 and the blade 51 are attracted together. It should be noted that the rear control plate 4 can be limited by directly and manually flipping it. After completion, the control plate 4 is adjusted.

[0029] like Figures 3-4 As shown, magnetic plates 8 that can attract each other are adhered to the rear end face of the welding machine body 1 and the side of the rear control plate 4 facing the welding machine body 1. It should be noted that when the rear control plate 4 is in the normal state, it is limited by the magnetic plates 8 on the rear end face of the welding machine body 1 and the side of the rear control plate 4 facing the welding machine body 1, so as to avoid unnecessary movement of the rear control plate 4 when the welding machine body 1 moves.

[0030] like Figures 3-4 As shown, the rear end face of the welding machine body 1 is provided with a wire harness hole 6 that communicates with its interior. The rear control board 4 has a wire harness frame 7 integrally formed on the side facing the welding machine body 1. The wire harness hole 6 and the wire harness frame 7 are configured to cooperate with each other. The wire harness in the rear control board 4 extends from the wire harness hole 6 and the wire harness frame 7 into the welding machine body 1.

[0031] Specifically, the rear control board 4 needs to have a wiring harness inside, which connects to the internal parts of the welding machine body 1 so that the rear control board 4 can be used normally. It should be noted that the wiring harness inside the rear control board 4 extends from the wiring harness hole 6 and the wiring harness frame 7 into the welding machine body 1. When the rear control board 4 is in the normal state, the wiring harness is covered by the wiring harness hole 6 and the wiring harness frame 7 to prevent the wiring harness from being directly exposed to the outside. The wiring harness hole 6 is closed by the wiring harness frame 7 to prevent impurities from entering.

[0032] Both the wire harness hole 6 and the wire harness frame 7 are arc-shaped, and the axis of the arc coincides with the axis of the rotation point of the rear control plate 4. Specifically, when the rear control plate 4 needs to rotate, the wire harness frame 7 will also move accordingly. By setting both the wire harness hole 6 and the wire harness frame 7 to be arc-shaped, the wire harness hole 6 and the wire harness frame 7 can be opened and closed smoothly.

[0033] like Figures 6-7 As shown, the rear end face of the welding machine body 1 also has a heat dissipation vent 9. Inside the heat dissipation vent 9 are fan blades driven by a motor. A ring 91 with its axis coinciding with the axis of the heat dissipation vent 9 is fixed on the rear end face of the welding machine body 1. The diameter of the ring 91 is larger than the diameter of the heat dissipation vent 9. A sealing ring 93 for pressing against the rear control plate 4 is attached to the outer end face of the ring 91. An air exchange port 92 communicating with the interior of the ring 91 is opened on the outer arc surface of the ring 91. When the rear control plate 4 is pressed against the sealing ring 93, the air exchange port 92 is used to ventilate the interior of the welding machine body 1.

[0034] Specifically, the heat dissipation vent 9 can be blocked by the rear control panel 4 in its normal position, and an air exchange vent 92 is provided on the outer arc surface of the ring 91. The air exchange vent 92 is set downward, which can change the direction of air in and out of the heat dissipation vent 9, avoid the heat dissipation vent 9 from being horizontally ventilated, and to a certain extent avoid the direct inward intake of external impurities. It should be noted that the downward orientation of the air exchange vent 92 can allow the gas to move from below into the heat dissipation vent 9, which to a certain extent avoids the horizontal inward adsorption of impurities.

[0035] like Figures 6-7 As shown, a second ring 95 is fitted around the outer ring of ring 1 91, which contacts the outer arc surface of ring 1 91. The outer arc surface of ring 2 95 has an air vent 2 96 that communicates with its interior. Rotating ring 2 95 can control the degree of overlap between air vent 1 92 and air vent 2 96.

[0036] Specifically, by setting ring 2 95, the ventilation port 1 92 and ventilation port 2 96 can be rotated and opened and closed. When the main body 1 of the welding machine is not in use, the heat dissipation port 9 can be sealed to a certain extent to minimize the influence of the outside world.

[0037] like Figures 6-7 As shown, a retaining plate 94 is fixed on the inner side of the rear frame 3. The retaining plate 94 abuts against the outer side of the second ring 95 to limit the second ring 95. The second ring 95 is restricted and can rotate. It should be noted that due to its restriction, it requires a certain amount of force to rotate manually. Under normal circumstances without manual operation, the second ring 95 will not rotate.

[0038] Both the outer arc surface of ring 1 (91) and the inner arc surface of ring 2 (95) are smoothly designed and fit together, so that ring 2 (95) can rotate relatively smoothly without getting stuck.

[0039] Working principle: When the main body 1 of the welding machine is in normal use, the magnetic plates 8 at the rear end of the main body 1 and the outer end of the rear control plate 4 attract each other, so that the rear control plate 4 is embedded in the rear frame 3, and the main body 1 of the welding machine is in normal use. Secondly, when the rear control panel 4 is flipped, the magnetic block 55 at the upper end of the rear control panel 4 attracts the blade 51, causing the rear control panel 4 to be flipped 180 degrees, and as... Figure 5 The orientation of the display screen 1 2 and the display screen 2 41 shown is the same, so that the display screen 2 41 can be used as a sub-display screen of the display screen 1 2. It should be noted that the display screen 2 41 can display the same as the display screen 1 2 or display a different display screen. It should also be noted that the display technology of the display screen 2 41 and the display screen 1 2 is already a mature technology.

[0040] After flipping the rear control board 4 as described above, the switch 42 and power cord 43 are aligned with the display screen 2 of the welding machine body 1. This allows the wire harnesses on the rear control board 4 and the front end of the welding machine body 1 to be bundled together, preventing the wire harnesses from becoming tangled. It should be noted that after the wire harnesses are bundled together, it can prevent the wire harnesses from being bent at the points extending from the rear control board 4 or the welding machine body 1, thus preventing fatigue.

[0041] When the rear control plate 4 and the rear frame 3 are engaged, the sealing ring 93 at the outer end of ring 91 is pressed against the rear control plate 4, which can block the heat dissipation vent 9 in harsh environments, preventing the heat dissipation vent 9 from directly driving the airflow to enter and exit laterally, thus preventing a large amount of impurities from entering during external exchange. In addition, by rotating ring 95, the degree of overlap between air exchange vent 92 and air exchange vent 96 is changed, which is equivalent to turning the air intake on and off. When not in use, it can be closed to reduce the impact of the environment on the interior of the welding machine body 1. It should be noted that even though the heat dissipation vent 9 is blocked by the rear control plate 4, air exchange vent 92 and air exchange vent 96 can still exchange air, changing the air exchange direction. When the rear control plate 4 is in normal condition, it avoids affecting the use of the welding machine body 1.
