Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to a welding device for an electric energy metering box. Background Art

[0002] The electricity meter box is a key equipment for electricity metering and is widely used in power systems. The main structure of the electricity meter box is usually formed by welding. When the electricity meter box is manufactured, its back plate needs to be evenly spot-welded and fixed, and a handheld welding gun is usually used for operation. The welding quality of the electricity meter box is directly related to the structural strength and service life of the electricity meter box. The current electricity meter box welding device is not convenient for accurately controlling the welding spacing. At the same time, the uniformity of the welding points during manual handheld welding gun operation is not good, and it is not convenient to control the welding down pressure, which easily affects the size of the molten pool. It is also not convenient to automatically prevent the welding wire from blocking. The traditional handheld welding gun method is not convenient for shaking the welding wire to prevent blocking, and the welding wire blocking rate is high. Manual operation adjustment is time-consuming and labor-intensive and not timely enough. It is also not convenient for automatic control of anti-burn-through welding. The wall thickness of the electricity meter box is relatively thin, which easily causes welding through and affects the welding quality. Therefore, the present application provides an electricity meter box welding device to meet the needs. Summary of the Invention

[0038] like Figures 1 to 10As shown, an embodiment of the present invention provides an electric energy meter box welding device, including a handheld welding part 1, a downward pressure adapter 2 is installed on the handheld welding part 1, and a rolling control part 3 is installed on the downward pressure adapter 2; the rolling control part 3 is used to control the welding interval; the downward pressure adapter 2 is used to control the downward pressure of the welding wire; a power connection safety part 4 is installed on the handheld welding part 1; a rotating shaking part 5 is installed at the bottom of the handheld welding part 1; the rotating shaking part 5 is used to shake the welding wire; an anti-burn-through part 6 is installed on the handheld welding part 1; the anti-burn-through part 6 is used to push the rolling control part 3; the handheld welding part 1 includes: a welding gun handle 101, a welding gun barrel 102 and a welding gun head 1021, the welding gun handle 101 is fixedly mounted with the welding gun barrel 102, and the welding gun barrel 102 is a steel pipe bending structure; the end of the welding gun barrel 102 is fixedly mounted with the welding gun head 1021; the welding gun head 1021 is a hexagonal structure; and a control switch is provided on the welding gun handle 101.

[0039] like Figures 3 to 6 As shown, the handheld welding piece 1 also includes a swivel ring 103 fixedly mounted on the end of the welding gun head 1021; the welding wire passes through the middle of the swivel ring 103; two main power plates 104 are fixedly mounted on the welding gun tube 102; the two main power plates 104 are elastic steel sheet structures; the ends of the two main power plates 104 are bent; the down-pressing adapter 2 includes a lifting sleeve 201 slidably sleeved on the welding gun head 1021; the lifting sleeve 201 is provided with a hexagonal hole; the lifting sleeve 201 is fixedly mounted with Two height power strips 202; an anti-accidental touch spring 203 is sleeved on the welding gun head 1021; the anti-accidental touch spring 203 is connected between the lifting sleeve 201 and the welding gun head 1021; two spaced power strips 204 are fixedly installed on the lifting sleeve 201; the two spaced power strips 204 are elastic structures; the rolling control part 3 includes a running wheel 301 rotatably mounted on the lifting sleeve 201; the outer side of the running wheel 301 is provided with a rubber coating; two power rings are fixedly sleeved on the running wheel 301 302, there is a gap between the two power connection rings 302; the outer sides of the two power connection rings 302 are recessed in the inner side of the walking wheel 301; there are four slots on the walking wheel 301; the two main power connection plates 104 elastically fit the power connection rings 302 respectively; six spaced power connection blocks 303 are embedded on the walking wheel 301, and the six spaced power connection blocks 303 are grouped in twos, and the two spaced power connection plates 204 are used to elastically fit the spaced power connection blocks 303 respectively; the walking wheel 301 is used to roll and fit the inside of the meter box. The use of the rolling control part 3 can facilitate the staff to perform fixed-distance welding work, which can improve the welding accuracy of this structure and avoid the problem of poor accuracy and affecting the welding quality when manual fixed-distance welding is performed. This structure uses power supply control to improve welding accuracy and reduce the difficulty of operation for staff. It can cooperate with the walking wheel 301 to roll and support the surface of the back plate of the electricity metering box. The evenly distributed welds make the stress distribution more balanced, avoid local stress concentration, and improve the overall mechanical strength of the back plate of the electricity metering box.

[0040] like Figures 3 to 5 As shown, the power-connecting safety component 4 includes a safety spring piece 401 fixedly installed on the welding gun head 1021 by bolts; two elevation power-connecting strips 402 are fixedly installed on the safety spring piece 401; the two elevation power-connecting strips 402 are respectively attached to the two height power-connecting strips 202; the safety spring piece 401 is an elastic structure; the elevation power-connecting strip 402 is used to prevent the welding wire from being over-pressed, and the downward pressure adapter 2 is used in conjunction with the power-connecting safety component 4. During welding, it can be ensured that the walking wheel 301 can roll and displace on the surface of the back plate of the electricity metering box to ensure accurate control of the welding spacing, otherwise the power cannot be connected normally. At the same time, this structure can be used to control the downward pressure of the staff during hand-held welding to avoid excessive or too small downward pressure affecting the size of the weld pool and the welding quality, and can improve the uniformity of each weld point during welding, while avoiding problems such as cold welding. Stable downward pressure can ensure that the welding wire is in full contact with the base material to avoid cold welding or unfused defects. , and at the same time reduce spatter, especially when welding thin plates, excessive pressure will cause deformation, and insufficient pressure may cause incomplete welding. Hold and press the welding gun handle 101, and then the elevation connection bar 402 will contact the height connection bar 202 to ensure that the downward pressure of the welding wire is within an appropriate range. As the welding gun is moved, keep the walking wheel 301 rolling on the back plate, the main connection piece 104 elastically fits the connection ring 302 for power supply, and the connection ring 302 supplies power to the interval connection block 303. When the interval connection block 303 is driven by the walking wheel 301 to move to the fit interval connection piece 204, the power supply path can be realized. The switch on the welding gun handle 101 held by the staff is also kept on, and one spot welding can be achieved. As the welding gun handle 101 continues to be moved, the walking wheel 301 continues to roll, and the three groups of interval connection blocks 303 can be used for interval power supply. The spacing between the three groups of interval connection blocks 303 is consistent, and the spot welding spacing is kept consistent.

[0041] like Figures 4 to 7As shown, the rolling control member 3 also includes four friction strips 304 fixedly mounted on the running wheel 301; the two sides of the friction strips 304 are respectively arc-shaped structures, and the surface of the four friction strips 304 is a frosted structure; the friction strips 304 are convex structures; there are intervals between the four friction strips 304; the rotary rocking member 5 includes a rotating ring 501 rotatably mounted on the bottom of the rotating ring 103; a rubber sleeve is provided on the outside of the rotating ring 501, and the four friction strips 304 are respectively used to rub the rubber sleeve on the outside of the rotating ring 501; the rotating ring 501 is provided with a rubber sleeve, and the four friction strips 304 are used to rub the rubber sleeve on the outside of the rotating ring 501; the rotating ring 501 is provided with a rubber sleeve. A welding wire guide ring 502 is fixedly mounted on the moving coil 501; the inner ring of the welding wire guide ring 502 is chamfered; the welding wire passes through the welding wire guide ring 502; the through hole in the rotating coil 501 is eccentric to the welding wire guide ring 502; the rotary shaking member 5 also includes a torsion spring 503 sleeved on the rotary ring 103, and the end of the torsion spring 503 is connected to the rotating coil 501, and the other end of the torsion spring 503 is connected to the rotary ring 103. By using the rotary shaking member 5, during the actual spot welding work, the welding can be carried out as the welding progresses. The automatic control shakes the welding wire without manual intervention. The welding wire can be automatically shaken after each welding is completed to keep the welding wire reset, ensuring the accuracy of the next spot welding position. At the same time, the wire blocking rate is reduced, and tedious manual operations are unnecessary. It also avoids burn accidents caused by manual shaking of the welding wire. The automatic shaking control method also avoids manual forgetfulness, thereby improving the sustainable usability of this structure. The shaking operation can prevent the molten welding wire from adhering to the inner wall of the conductive nozzle due to high temperature, and reduce the accumulation of metal spatter in the conductive nozzle hole. Especially during long-term continuous welding, slight swinging can interrupt the softening and deformation of the welding wire caused by local overheating. Periodic shaking makes it easier to separate the oxide scale or slag on the surface of the welding wire, preventing these impurities from clogging the wire feeding path. When the walking wheel 301 rolls, it can drive the friction strip 304 to rub the rubber sleeve on the outside of the rotating circle 501. At this time, the rotating circle 501 rotates to drive the eccentric welding wire guide ring 502 to shake the welding wire. Subsequently, under the drive of the torsion spring 503, the rotating circle 501 rotates in the opposite direction to drive the welding wire to reset.

[0042] like Figures 3 to 10As shown, the burn-through prevention member 6 includes a lifting frame 601 that is slidably sleeved on the welding gun tube 102; the lifting frame 601 is a U-shaped structure; the lifting frame 601 is fixedly mounted on the lifting sleeve 201 by bolts; a downward pressure magnet 6011 is fixedly mounted on the lifting frame 601; an electromagnet 602 is fixedly sleeved on the welding gun tube 102, and the electromagnet 602 is aligned with the downward pressure magnet 6011; the downward pressure magnet 6011 and the electromagnet 602 repel each other; the main power strip 104 and the height power strip 2 02, the interval connecting piece 204, the connecting ring 302, the interval connecting block 303, the elevation connecting strip 402, the electromagnet 602 and the control switch on the welding gun handle 101 are connected in series to the power supply; the anti-burning part 6 also includes a weld guide plate 603 fixedly installed at the bottom of the lifting frame 601; the bottom edge of the weld guide plate 603 is used to fit the weld to guide welding. The use of the anti-burning part 6 can be used to automatically control the spot welding speed during actual welding work, avoiding workers from long-term local welding. The anti-burn-through structure adopted in this structure can be automatically controlled and is more suitable for use in electric energy meter boxes with thinner plates. At the same time, the metal material produces thermal fatigue and thermal creep due to long-term high temperature, resulting in a decrease in mechanical strength. When the interval connection block 303 is driven by the walking wheel 301 to move to the spacer connection sheet 204, not only can the welding gun handle 101 be spot welded, but the electromagnet 602 can be energized to repel the pressing magnet 6011. At this time, the pressing magnet 6011 can be controlled to move downward by the magnetic force, thereby lifting the welding gun head 1021. At this time, the welding wire will also be separated from the molten pool while spot welding, avoiding excessive spot welding time. At the same time, the upward movement speed of the welding gun head 1021 can be controlled by the specifications of the electromagnet 602. The greater the magnetic force of the electromagnet 602, the faster the downward movement speed of the pressing magnet 6011.

[0043] The working principle provided by the present invention is that, first, when the worker holds the welding gun handle 101 to perform welding work, the welding wire is aligned with the weld, the walking wheel 301 is attached to the back plate of the electric energy metering box, and rolls in the direction of the weld, and the welding gun handle 101 is pressed down by the hand. At this time, the welding gun head 1021 moves up and down on the lifting sleeve 201. As the downward pressure stroke increases, the walking wheel 301 can be elastically attached to the back plate of the electric energy metering box, and then the elevation connection bar 402 will contact the height connection bar 202, ensuring that the downward pressure of the welding wire is within an appropriate range. The gun keeps the wheel 301 rolling on the back plate, the main power plate 104 elastically fits the power ring 302 for power supply, and the power ring 302 supplies power to the interval power block 303. When the interval power block 303 is driven by the wheel 301 to move to fit the interval power plate 204, the power supply path can be realized. The switch on the welding gun handle 101 held by the staff is also kept on, and one spot welding can be realized. In this way, as the wheel 301 rolls, spot welding is carried out one by one, and when the wheel 301 rolls, it can drive the friction strip 304 to rotate frictionally. The rubber sleeve on the outer side of the moving coil 501, at this time, the rotating coil 501 rotates to drive the eccentric welding wire guide ring 502 to shake the welding wire. At this time, the torsion spring 503 is twisted, and subsequently as the walking wheel 301 continues to roll, the friction strip 304 can be driven to pass through the rotating coil 501. When the rotating coil 501 is at the interval between the friction strips 304, the rotating coil 501 loses friction, and the torsion spring 503 drives the rotating coil 501 to rotate in the opposite direction to drive the welding wire to reset. At this time, the gap connecting block 303 is driven by the walking wheel 301 to move to the fitting gap. When the power strip 204 is connected, not only can the welding gun handle 101 be spot welded, but the electromagnet 602 can also be energized to repel the downward pressure magnet 6011. At this time, the downward pressure magnet 6011 can be controlled by the magnetic force to move downward, driving the walking wheel 301 to move downward as well, thereby lifting the welding gun head 1021. At this time, the welding wire will also be separated from the molten pool while being spot welded, thus avoiding excessively long spot welding time. The weld guide plate 603 can facilitate the staff to fit the weld guide plate 603 to the weld, and the staggered layers between the frame and the back plate of the energy metering box can be used to assist in guidance.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
