Description

Technical Field

[0001] This utility model relates to the field of inverter welding machine technology, specifically a lightweight display panel for inverter welding machines. Background Technology

[0002] Inverter welding machines, also known as inverter arc welding power supplies, are a new type of welding power supply. This type of power supply typically converts the three-phase power frequency (50Hz) AC grid voltage into DC through an input rectifier and filter. Then, through the alternating switching action of high-power switching electronic components (SCR, GTR, MOSFET, or IGBT), it is inverted into a medium-frequency AC voltage of several kHz to tens of kHz. Simultaneously, a transformer reduces this voltage to tens of volts suitable for welding, and finally, the voltage is rectified again and filtered by a reactor to output a relatively stable DC welding current.

[0003] In today's industrial manufacturing and maintenance fields, inverter welding machines, as key welding equipment, are widely used in many industries such as construction, machining, and automotive repair. With continuous technological advancements and increasingly diversified application scenarios, the performance requirements for inverter welding machines are also constantly rising.

[0004] In actual use, traditional welding machines typically operate in extremely complex environments, with frequent occurrences of collisions at construction sites, accidental impacts to tools, and vibrations during transport. These external impacts can easily damage the welding machine, affecting its normal operation and increasing maintenance costs and downtime. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight display panel for inverter welding machines, which solves the problem mentioned in the background art of damage caused by external impacts to welding machines, thereby affecting their normal use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight display panel for an inverter welding machine, comprising a welding machine body, a heat dissipation hole at one end of the welding machine body, a panel one and a panel two respectively at both ends of the welding machine body, both panels one and two being connected to the welding machine body by bolts, the components at both ends of the welding machine body being located within the panels, reinforcing ribs being fixedly provided inside both panels one and two, the reinforcing ribs being arranged in a grid pattern, a filter plate being fixedly installed in the middle of panel one, the filter plate being fitted to the heat dissipation hole.

[0007] Preferably, the inner walls of the two end panels of the filter plate are provided with rotating grooves, which are arranged vertically and equidistantly. The inner walls of the two end panels are provided with positioning hole one and positioning hole two.

[0008] Preferably, baffles are equidistantly arranged inside the panel, and a rotating shaft is fixedly arranged at both ends of the baffle. The baffle is rotatably installed in the corresponding rotating groove through the rotating shaft.

[0009] Preferably, a fixing rod is fixedly provided in the middle of the baffle, and annular grooves are provided at both ends of the fixing rod. A connecting rod is rotatably installed in the annular groove. The connecting rod is arranged vertically and has multiple rotating rings. The multiple rotating rings on the connecting rod correspond to the annular grooves of multiple sets of baffles.

[0010] Preferably, the fixed rod in the middle of the top baffle has grooves at both ends, the grooves are connected to the slide rail, a lever is slidably installed in the slide rail, the lever is fixedly connected to the moving block, the moving block is slidably installed in the groove, and one side of the moving block is connected to the groove by a spring.

[0011] Preferably, a limiting rod is fixedly installed on the other side of the movable block, and the limiting rod is adapted to positioning hole one and positioning hole two.

[0012] This invention provides a lightweight display panel for an inverter welding machine. It offers the following advantages:

[0013] (1) This utility model protects both ends of the welding machine through panel one and panel two. The internal structure of the panel enhances the overall strength of the panel. The mesh-like reinforcing ribs can effectively disperse the impact of external forces, so that when the panel is subjected to collision, impact or vibration, the stress is evenly distributed, reducing the possibility of panel breakage due to stress concentration.

[0014] (2) This utility model protects the filter plate by setting a baffle, so as to avoid a lot of dust and impurities adhering to the filter plate when the welding machine is not in use, which would affect the effect of the filter plate.

[0015] This solves the problem of external impacts damaging the welding machine and thus affecting its normal operation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5 A lightweight display panel for an inverter welding machine includes a welding machine body 1. One end of the welding machine body 1 is provided with a heat dissipation hole 11. The two ends of the welding machine body 1 are respectively provided with a panel 2 and a panel 3. The panel 2 and the panel 3 are both connected to the welding machine body 1 by bolts. The components at both ends of the welding machine body 1 are located in the panel. The interior of the panel 2 and the panel 3 are both fixedly provided with reinforcing ribs 25, which are arranged in a grid pattern. A filter plate 21 is fixedly installed in the middle of the panel 2, and the filter plate 21 is attached to the heat dissipation hole 11.

[0025] Specifically, panels 2 and 3 are bolted to both ends of the welding machine body 1, protecting the components at both ends of the welding machine body 1. The bolted connection also allows for quick disassembly and replacement of panels 2 and 3. The internal reinforcing ribs 25 are arranged in a grid pattern, enhancing the overall strength of the panels. The grid structure disperses external impacts, ensuring even stress distribution when the panels are subjected to collisions, vibrations, or other external forces. This prevents excessive localized stress and damage, effectively improving the panels' impact resistance and extending their service life. In complex working environments, the panels can better withstand external collisions and vibrations, ensuring the safety of the welding machine.

[0026] The filter plate 21 is attached to the heat dissipation hole 11, which can filter dust and impurities in the air and prevent these impurities from entering the welding machine during heat dissipation. When the welding machine is working, the heat dissipation hole 11 will draw in air, and the filter plate 21 can effectively filter the dust in the air to ensure the cleanliness of the air inside the welding machine.

[0027] Example 2:

[0028] To prevent dust and impurities from accumulating on filter plate 21 when the welding machine is idle, please refer to... Figures 1-5 Based on embodiment 1, rotating grooves 22 are provided on the inner walls of the two end panels 2 of the filter plate 21. The rotating grooves 22 are arranged vertically and equidistantly. Positioning holes 23 and 24 are provided on the inner walls of the two end panels 2.

[0029] The interior of panel 2 is provided with baffles 4 at equal intervals. Both ends of the baffles 4 are fixed with rotating shafts 41. The baffles 4 are rotatably installed in the corresponding rotating slots 22 through the rotating shafts 41.

[0030] A fixing rod 42 is fixedly installed in the middle of the baffle 4. Both ends of the fixing rod 42 are provided with annular grooves 421. A connecting rod 5 is rotatably installed in the annular grooves 421. The connecting rod 5 is arranged vertically and has multiple rotating rings. The multiple rotating rings on the connecting rod 5 correspond to the annular grooves 421 of multiple sets of baffles 4 respectively.

[0031] The top baffle 4 has a fixed rod 42 in the middle with grooves 43 at both ends. The grooves 43 are connected to the slide rail 46. A lever 47 is slidably installed in the slide rail 46. The lever 47 is fixedly connected to the moving block 44. The moving block 44 is slidably installed in the groove 43. One side of the moving block 44 is connected to the groove 43 by a spring 48.

[0032] A limiting rod 45 is fixedly installed on the other side of the movable block 44. The limiting rod 45 is adapted to the positioning hole 23 and the positioning hole 24.

[0033] Specifically, when the welding machine is idle, the baffle 4 can rotate in the rotating groove 22 via the rotating shaft 41, allowing multiple sets of baffles 4 to cooperate with each other, rotating from the open state to the closed state. At this time, the limiting rod 45 is in the positioning hole 23, thereby covering the filter plate 21. In this way, when the welding machine is idle, dust and impurities are prevented from falling directly onto the filter plate 21, reducing the accumulation of dust and impurities on the filter plate 21 and extending the single-use time of the filter plate 21.

[0034] When it is necessary to open the multiple sets of baffles 4 that are closed, manually move the lever 47. The lever 47 will slide in the slide rail 46. Since the lever 47 is fixedly connected to the moving block 44, the moving block 44 will slide synchronously with the lever 47 in the slide groove 43. The sliding of the moving block 44 will compress the spring 48, and the spring 48 will store elastic potential energy to provide power for the subsequent reset of the moving block 44. As the moving block 44 moves, the limiting rod 45 fixedly installed on the other side of the moving block 44 will move out of the positioning hole 23. At this time, the limiting rod 45 no longer fixes and limits the top baffle 4. After positioning hole 23, since baffle 4 is only rotatably installed in rotating groove 22 via rotating shaft 41, and connecting rod 5 can rotate in annular groove 421, baffle 4 can be manually rotated at this time to rotate multiple sets of baffles 4 from overlapping closed state to open state, thereby exposing filter plate 21 for heat dissipation and ventilation when the welding machine is working normally. To ensure the fixation of baffle 4, after aligning the limiting rod 45 with positioning hole 24, release the lever 47. Under the elastic force of spring 48, moving block 44 will drive limiting rod 45 into positioning hole 24 to fix the baffle 4 in open state.

[0035] Working principle: When the equipment is in use, panel 1 2 and panel 2 3 are installed at both ends of the welding machine body 1 with bolts, so that the components at both ends of the welding machine body 1 are within the protection range of the panels. When the welding machine is idle, multiple sets of baffles 4 cooperate with each other to be in a closed state. At this time, the limit rod 45 is in the positioning hole 1 23, covering the filter plate 21, preventing dust and impurities from falling directly onto the filter plate 21, and reducing the accumulation of dust and impurities on the filter plate 21.

[0036] When the welding machine is needed, the control lever 47 slides in the slide rail 46, driving the moving block 44 to slide synchronously in the slide groove 43, compressing the spring 48. As the moving block 44 moves, the limiting rod 45 moves out of the positioning hole 23, releasing the fixed limit on the top baffle 4. The baffle 4 is manually rotated, causing multiple sets of baffles 4 to rotate from the overlapping closed state to the open state, exposing the filter plate 21. After the limiting rod 45 is aligned with the positioning hole 24, the control lever 47 is released. Under the elastic force of the spring 48, the moving block 44 drives the limiting rod 45 into the positioning hole 24, fixing the baffle 4 in the open state. At this time, the welding machine can work normally for heat dissipation and ventilation.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
