Description

Technical Field

[0001] This utility model relates to the field of inverter welding machine technology, specifically a double-plate inverter welding machine. Background Technology

[0002] In the operation of an inverter welding machine, the three-phase or single-phase 50Hz power frequency AC current is rectified and filtered to obtain a relatively smooth DC current. The inverter circuit composed of IGBTs or MOSFETs converts the DC current into AC current of 15-100kHz. After being stepped down by the intermediate frequency main transformer, it is rectified and filtered again to obtain a stable DC output welding current (or the AC current of the required frequency is inverted again). The inverter welding machine usually has a power supply board, a secondary rectifier board and an inverter board. The input voltage is converted into DC current by the power supply board and sent to the inverter board. Through the switching action of the MOSFETs or IGBTs, the DC current is converted into AC current and sent to the transformer in the secondary rectifier board. The secondary output of the transformer is converted back into DC current by the secondary rectifier tubes.

[0003] During prolonged use, the internal power board, secondary rectifier board, and inverter board of a dual-plate inverter welding machine are prone to damage, requiring maintenance. However, due to the complex internal structure of dual-plate inverter welding machines, most existing power boards, secondary rectifier boards, and inverter boards are typically installed internally using bolts. This results in complex electrical connection wiring, making disassembly inconvenient and reducing maintenance efficiency. Furthermore, disassembly and assembly can easily damage the power board, secondary rectifier board, and inverter board. Therefore, a dual-plate inverter welding machine needs to be designed to solve these problems. Utility Model Content

[0004] To solve the above technical problems, this application provides a dual-plate inverter welding machine, including a power board, a secondary rectifier board and an inverter board. Fixing plates are provided on the left and right sides of the power board, the secondary rectifier board and the inverter board, and support blocks and locking blocks are provided at the front and rear ends of the left and right sides of the power board, the secondary rectifier board and the inverter board.

[0005] The upper end of each support block is provided with a threaded post and a locking hole. The upper end of each threaded post is threaded with a locking bolt. The bottom end of each locking block is provided with a locking post. The left and right sides, front and rear ends of each power board, secondary rectifier board and inverter board are provided with a first docking hole and a second docking hole. Each locking block is provided with a plug-in hole.

[0006] Both the clip and the post pass through the second mating hole and are engaged and connected to the inside of the clip and the hole. Both the insertion hole and the first mating hole are sleeved on the outside of the threaded post.

[0007] In some embodiments, a plurality of support protrusions are equidistantly arranged on the inner side of the fixing plate, and the support blocks are arranged between two adjacent support protrusions. The front and rear parts of the outer side of the support blocks are provided with first fixing bolts.

[0008] In some embodiments, extension plates are provided on both the upper and lower sides of the fixing plate, and reinforcing beams are provided at all four corners of the fixing plate.

[0009] In some embodiments, mounting columns are provided at both the front and rear ends of the inner side of the extension plate, and openings and second fixing bolts are provided at both the left and right ends of the reinforcing beam.

[0010] In some embodiments, the fixing plates are all 3mm thick stainless steel plates, the support blocks are made of stainless steel, and the locking blocks are all made of rubber.

[0011] In some embodiments, the installation spacing between the power board, the secondary rectifier board and the inverter board is 10cm.

[0012] This utility model has at least the following beneficial effects:

[0013] In this invention, the power board, secondary rectifier board, and inverter board are first installed on the inner side of the fixing plate using a support block and a locking block. Then, the locking block's bottom end uses a clip and post to engage with a clip and hole, while the insertion hole and the first mating hole are both fitted onto the outer side of the threaded post. This allows the locking block to fix the power board, secondary rectifier board, and inverter board to the upper end of the support block. Finally, a locking bolt is used to thread the upper end of the threaded post. This increases the ease of installation and disassembly of the power board, secondary rectifier board, and inverter board, while also increasing their installation stability. During the installation and disassembly process, this not only improves the maintenance speed but also prevents damage to the power board, secondary rectifier board, and inverter board.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example 1:

[0025] Please see Figure 1-8 This utility model provides a technical solution: a dual-plate inverter welding machine, including a power board 2, a secondary rectifier board 3 and an inverter board 4. The power board 2, the secondary rectifier board 3 and the inverter board 4 are all provided with a fixing plate 1 on the left and right sides. The power board 2, the secondary rectifier board 3 and the inverter board 4 are all provided with a support block 5 and a locking block 6 at the front and rear ends of the left and right sides. The power board 2, the secondary rectifier board 3 and the inverter board 4 are installed on the inside of the fixing plate 1 by the support block 5 and the locking block 6.

[0026] The upper end of each support block 5 is provided with a threaded post 501 and a locking hole 503. The upper end of each threaded post 501 is threaded with a locking bolt 502. The bottom end of each locking block 6 is provided with a locking post 602. The left and right sides, front and rear ends of each power board 2, secondary rectifier board 3 and inverter board 4 are provided with a first docking hole 8 and a second docking hole 9. Each locking block 6 is provided with a plug-in hole 601. The locking post 602 at the bottom end of the locking block 6 engages with the locking hole 503. At the same time, the plug-in hole 601 and the first docking hole 8 are both sleeved on the outside of the threaded post 501, so that the locking block 6 fixes the power board 2, secondary rectifier board 3 and inverter board 4 to the upper end of the support block 5.

[0027] Both the clip and the post 602 pass through the second mating hole 9 and are clipped and connected to the inside of the clip and hole 503. The insertion hole 601 and the first mating hole 8 are both sleeved on the outside of the threaded post 501.

[0028] Furthermore: Several support protrusions 101 are evenly spaced on the inner side of the fixing plate 1, and support blocks 5 are all set between two adjacent support protrusions 101. First fixing bolts 10 are set on the front and rear parts of the outer side of the support blocks 5. The first fixing bolts 10 facilitate the installation and disassembly of the support blocks 5 and the fixing plate 1. The support blocks 5 are set between two adjacent support protrusions 101 to support the support blocks 5, which facilitates installation and prevents them from falling off.

[0029] Furthermore, extension plates 102 are provided on both the upper and lower sides of the fixed plate 1, and reinforcing beams 7 are provided at the four corners of the fixed plate 1. The two fixed plates 1 are connected into a whole by the reinforcing beams 7, which increases the structural strength and facilitates installation inside the inverter welding machine housing.

[0030] Furthermore, mounting posts 103 are provided at both the front and rear ends of the inner side of the extension plate 102, and openings 701 and second fixing bolts 11 are provided at both the left and right ends of the reinforcing beam 7. The openings 701 and the second fixing bolts 11 facilitate the connection between the reinforcing beam 7 and the extension plate 102, and also facilitate installation and disassembly.

[0031] Furthermore: the fixing plate 1 is made of 3mm thick stainless steel, the support block 5 is made of stainless steel, and the locking block 6 is made of rubber. The fixing plate 1, made of 3mm thick stainless steel, is not easily damaged. At the same time, it strengthens the structure and prevents the protection performance of the power board 2, secondary rectifier board 3 and inverter board 4 from being reduced due to bumps during movement. The stainless steel support block 5 is easy to install, and the rubber locking block 6 is easy to engage with the support block 5. At the same time, it can stably fix the power board 2, secondary rectifier board 3 and inverter board 4 without damaging their surfaces.

[0032] Furthermore, the installation spacing between the power board 2, the secondary rectifier board 3, and the inverter board 4 is 10cm, which provides sufficient plug-in space for electrical connections between the power board 2, the secondary rectifier board 3, and the inverter board 4, and also facilitates heat dissipation.
