DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a copper bar welding fixing device, the structure of which is as follows Figure 1 As shown, it includes a supporting component 1, a fixing component 2 and a first locking component 3.

[0024] The support assembly 1 includes four symmetrically distributed vertical poles 11 and a frame 12 fixedly connected between the tops of the four vertical poles 11. Two horizontal bars 14 for receiving copper bars 13 are fixedly connected to the frame 12 at intervals in sequence along the length direction of the frame 12, and the two horizontal bars 14 are parallel.

[0025] The fixing assembly 2 includes four pressing plates 21 movably connected to the top of the frame 12 . The four pressing plates 21 are arranged in sequence along the length direction of the frame 12 . The pressing plates 21 are used to abut against multiple copper bars 13 at the same time to fix the multiple copper bars 13 .

[0026] The first locking assembly 3 is disposed on the frame 12 , and is used to lock the pressing plate 21 with the frame 12 , and to make the pressing plate 21 abut against a plurality of copper bars 13 at the same time.

[0027] When in use, multiple copper bars 13 to be welded are placed on the cross bar 14 in sequence, the pressing plate 21 is placed on the top of the copper bar 13, and the pressing plate 21 is fixed using the first locking component 3. The pressing plate 21 is pressed against multiple copper bars 13 at the same time, the copper bars 13 are fixed, and the gaps between adjacent copper bars 13 are welded, so that multiple copper bars 13 can be welded at the same time, reducing the frequency of fixing and adjusting the copper bars 13, and improving production efficiency and production quality.

[0028] In the utility model, under the action of the first locking assembly 3, the pressing plate 21 can fix multiple copper bars 13 on the cross bar 14 at the same time, so that multiple copper bars 13 can be welded at the same time, reducing the frequency of fixing and adjusting the copper bars 13 and improving production efficiency and production quality.

[0029] To fix the pressing plate 21, please refer to Figure 1 In a preferred embodiment, the first locking assembly 3 includes first screws 31 fixedly connected to both sides of the frame 12, the first screws 31 are perpendicular to the frame 12, the pressure plate 21 is slidably connected to the two first screws 31, and each of the first screws 31 is threadedly connected to a first nut 32, and the first nut 32 abuts against the top of the pressure plate 21.

[0030] When in use, after placing multiple copper bars 13 on the crossbar 14, the pressing plate 21 is sleeved on the first screw 31, the pressing plate 21 overlaps the multiple copper bars 13, and the first nut 32 is tightened until the first nut 32 is pressed against the pressing plate 21. At this time, the pressing plate 21 is pressed against the multiple copper bars 13, and the multiple copper bars 13 are fixed. The operation is convenient, the fixation is stable, and the production efficiency and production quality are improved.

[0031] In order to facilitate the replacement of the first screw rod 31, please refer to Figure 1 In a preferred embodiment, a screw barrel 33 is fixedly connected to both sides of the frame 12 , the screw barrel 33 is perpendicular to the frame 12 , the screw barrel 33 is adapted to the first screw rod 31 , and the first screw rod 31 is threadedly connected to the screw barrel 33 .

[0032] During use, due to various reasons such as the collision of the copper bar 13, the threads on the first screw rod 31 are easily damaged, resulting in the inability to tighten the first nut 32. The first screw rod 31 is threadedly connected to the screw barrel 33, which is convenient for disassembly and assembly, and is easy to replace the first screw rod 31, thereby improving production efficiency.

[0033] In order to improve the stability of the pressure plate 21, please refer to Figure 1 In a preferred embodiment, a gasket 34 is slidably connected to the first screw rod 31 , and the gasket 34 is located between the first nut 32 and the pressure plate 21 .

[0034] When in use, the contact area between the first nut 32 and the pressing plate 21 is increased, thereby improving the stability of the fixation.

[0035] To improve the replacement efficiency of copper bar 13, please refer to Figure 1 In a preferred embodiment, a through hole 22 for the first screw rod 31 to pass through is provided on one side of the pressing plate 21, and a notch 23 for the first screw rod 31 to pass through is provided on the other side of the pressing plate 21.

[0036] When using, when replacing the copper bar 13, after loosening the two first nuts 32, use the through hole 22 as the rotation axis, rotate the pressing plate 21 along the direction of the notch 23, so that the pressing plate 21 and the copper bar 13 are misaligned, and the copper bar 13 can be removed. When replacing the copper bar 13, it is not necessary to completely remove the pressing plate 21, which is not only convenient to operate and improve production efficiency, but also reduces the possibility of losing the pressing plate 21 and reduces production costs.

[0037] In order to improve the stability of the pressure plate 21, please refer to Figure 1 In a preferred embodiment, an anti-skid layer is provided at the bottom of the pressing plate 21, and the anti-skid layer is a rubber pad.

[0038] During use, when the pressing plate 21 abuts against the copper busbar 13, the anti-skid layer is squeezed and deformed, which not only makes the pressing plate 21 and the copper busbar 13 fit more closely, but also increases the friction between the pressing plate 21 and the copper busbar 13, making the fixation more stable, reducing the possibility of sliding and deflecting of the copper busbar 13, and improving the production quality.

[0039] For increased security, please refer to Figure 1 In a preferred embodiment, the circumferential side of the pressing plate 21 is provided with a circular chamfer.

[0042] When in use, the reinforcing ribs 15 support the adjacent uprights 11, thereby improving the overall strength of the fixing device, increasing the service life of the fixing device, and reducing production costs.

[0044] When in use, the second locking assembly 5 is used to fix the limit plate 4 to the end of the frame 12. The limit plate 4 is higher than the frame 12. When the copper bar 13 is placed on the cross bar 14, the end of the copper bar 13 is abutted against the limit plate 4. The limit plate 4 limits the copper bar 13, reducing the possibility of sliding and deflecting the copper bar 13 along the length direction of the frame 12, thereby improving the production quality.

[0045] To fix the limit plate 4, please refer to Figure 1 In a preferred embodiment, the second locking assembly 5 includes a second screw 51 fixedly connected to the end of the frame 12, the second screw 51 is perpendicular to the cross bar 14, the limiting plate 4 is slidably connected to the second screw 51, and the limiting plate 4 is provided with a strip hole 52 for the second screw 51 to pass through, and the second screw 51 is threadedly connected with a second nut 53, and the second nut 53 abuts against the limiting plate 4.

[0046] When in use, the limiting plate 4 is sleeved on the second screw rod 51, and the height of the limiting plate 4 is adjusted along the strip hole 52 according to the thickness of the copper bar 13, so that the limiting plate 4 is higher than the copper bar 13, and the second nut 53 is tightened until the limiting plate 4 is pressed against the side of the frame 12, and the limiting plate 4 is fixed. The operation is convenient and the fixation is stable.
