[0037] The existing 5G chassis cabinet 2 is manufactured from a single piece of board, such as Figures 6-9 As shown, cabinet 2 includes a top panel 21, a bottom panel 22, a left panel 23, a right panel 24, and a rear panel 25. The bottom panel 22, left panel 23, right panel 24, and rear panel 25 are all connected to the top panel 21. Each panel is bent, forming a first right-angle bend 26 between the left end of the top panel 21 and the left panel 23, a second right-angle bend 27 between the lower end of the left panel 23 and the left end of the bottom panel 22, a third right-angle bend 28 between the right end of the bottom panel 22 and the lower end of the right panel 24, and a fourth right-angle bend 29 between the rear end of the bottom panel 22 and the lower end of the rear panel 25. Specifically, a first connecting plate 32 is formed by a right-angle bend at the upper end of the right panel 24, and second connecting plates 33 are formed by right-angle bends at the left, right, and top ends of the rear panel 25. The first connecting plate 32 is welded to the lower left sidewall of the top panel 21, and the third connecting plate 33 is formed by the right-angle bends. The two connecting plates 33 are welded to the inner rear wall of the right panel 24, the inner rear wall of the top panel 21, and the inner rear wall of the left panel 23, respectively, to form a fully connected cabinet 2. A partition 36 is provided in the middle of the cabinet 2 along the front-to-back direction, dividing the cabinet 2 into a left cavity and a right cavity. The left cavity is used to install heat dissipation components, and the right cavity is used to install electrical components. Correspondingly, the front walls of the top panel 21, the bottom panel 22, the left panel 23, and the right panel 24 are all bent, and the front side of the partition 36 is also bent. The bend on the left side of the top panel 21, the bend on the left side of the bottom panel 22, and the bend on the front side of the left panel 23 form a left opening 37, which is used to install an air intake panel. The bend on the right side of the top panel 21, the bend on the right side of the bottom panel 22, the bend on the front side of the partition 36, and the bend on the front side of the right panel 24 form a right opening 38, which is used to install an operation panel.

[0038] Specifically, in order to ensure the dimensions of the aforementioned cabinet 2 during welding, such as Figures 1-10As shown, this utility model embodiment provides a 5G chassis cabinet welding and fixing fixture, specifically including a mounting plate 11 and an upper pressure plate. The mounting plate 11 is equipped with a front fixing component 12, a right fixing component 13, a rear fixing plate 14, and a left fixing plate 15. The front fixing component 12 is used to fix the size of the opening of the cabinet 2. The right fixing component 13 and the left fixing plate 15 are used together to fix the width of the cabinet 2 and ensure the perpendicularity of the left panel 23 and the right panel 24. The rear fixing plate 14 is used to ensure the perpendicularity of the rear panel 25 and, together with the front fixing component 12, to ensure the front-to-back dimensions of the cabinet 2. The upper pressure plate is placed on the upper panel 21 during the welding process and is used to cooperate with the mounting plate 11 to ensure the height of the cabinet 2, thereby ensuring that the dimensions of the cabinet 2 are not affected by the welding during the entire welding process.

[0039] Specifically, the front fixing assembly 12 includes a front drive device 121 and a front fixing plate. The front sidewall of the front fixing plate is connected to the output shaft of the front drive device 121. The front drive device 121 drives the front fixing plate to move in the front-back direction, so that the front fixing plate can be inserted into the opening and abut against the inner sidewall of the bend, thereby supporting the opening and ensuring the processing dimensions of the opening during the welding process. At the same time, the front fixing plate also abuts against the front sidewall of the bend. The rear fixing plate 14 abuts against the rear sidewall of the rear panel 25. Because the rear fixing plate 14 is set in a vertical state, it ensures the front-back dimensions of the entire cabinet 2, that is, the length dimension.

[0040] Specifically, the right fixing component 13 includes a right drive device 131 and a right fixing plate 132. The right side wall of the right fixing plate 132 is connected to the output shaft of the right drive device 131. The right drive device 131 can drive the right fixing plate 132 to move in the left and right directions, so that the right fixing plate 132 abuts against the right panel 24. Furthermore, a first protrusion 133 is provided on the upper part of the left side wall of the right fixing plate 132. The lower side wall of the first protrusion 133 abuts against the upper side wall of the right panel 24. If it abuts against the right angle bend, it further restricts the horizontality of the first connecting plate 32, preventing it from warping and affecting the height dimension of the cabinet 2, and also ensuring the verticality of the right panel 24. If it abuts against the upper side wall of the right panel 24, it ensures the verticality of the right panel 24. At the same time, the left fixing plate 15 abuts against the left side wall of the left panel 23. Because the left fixing plate 15 is set in a vertical state, it ensures the left and right dimensions of the entire cabinet 2, that is, the width dimension. Both the right drive unit 131 and the front drive unit 121 mentioned above are existing cylinders.

[0041] Correspondingly, a rectangular mounting hole 39 is provided on the rear panel 25 of the cabinet 2, specifically located on the rear cavity wall of the right cavity, for installing electrical components. Correspondingly, a fixing block 16 is provided on the rear fixing plate 14 in this embodiment. The fixing block 16 is designed with an L-shaped structure, with one end of the fixing block 16 located on the outer wall of the rear fixing plate 14, and the other end inserted into the mounting hole 39 inside the cabinet 2, limiting the outer wall of the rear fixing plate 14 between the fixing block 16 and the rear fixing plate 14, thereby fixing the rear panel 25 and ensuring the verticality of the rear panel 25. Furthermore, at least one fixing block 16 can be provided on each of the four hole walls of the mounting hole 39 to fix the rear panel 25 in the four directions of the mounting hole 39 and ensure the verticality of the rear panel 25. In this embodiment, two fixing blocks 16 are provided on the upper hole wall and the left hole wall of the mounting hole 39.

[0042] Furthermore, the upper side wall of the fixing block 16 located inside the cabinet 2 abuts against the second connecting plate 33, thereby ensuring the horizontality or verticality of the second connecting plate 33, ensuring the stability of the second connecting plate 33 when welding with the other panels, and thus ensuring the dimensions of the cabinet 2 at the rear panel 25.

[0043] Furthermore, the fixing block 16 is provided with an upward-facing first step surface 161 on the side wall near the mounting plate 11. The first step surface 161 abuts against the hole wall of the mounting hole 39, thereby supporting the entire mounting hole 39, ensuring that the size of the entire mounting hole 39 is not easily deformed during the welding process, and ensuring that the panel subsequently installed at the mounting hole 39 can be stably installed.

[0044] Specifically, multiple left fixing plates 15 are provided, evenly distributed along the front-to-back direction, and the height of the left fixing plates 15 is the same as or greater than the height of the cabinet 2, thereby ensuring the verticality of the entire left panel 23. In this embodiment, three left fixing plates 15 are provided and are installed on the mounting plate 11 by bolts.

[0045] Specifically, the opening is divided into a front opening and a rear opening. Correspondingly, the front fixed plate includes a left front plate 122 and a right front plate 123. Two front drive devices 121 are provided, and the drive shafts of the two front drive devices 121 are respectively connected to the left front plate 122 and the right front plate 123, driving the left front plate 122 and the right front plate 123 to move in the front-back direction. The rear side wall of the left front plate 122 is provided with a fixing groove 124. There are three fixing grooves 124, which are respectively provided at the left end, the lower end and the upper end of the rear side wall of the left front plate 122, for bending of the left side of the upper panel 21 and the lower panel 21, respectively. 2. The bend on the left side and the bend on the front side of the left panel 23 are inserted to fix the bend at the left opening 37 and ensure the size of the left opening 37. The right front panel 123 has a second protrusion 125 with a rectangular structure in the middle of the rear side wall, which forms four second step surfaces 126 with the side wall of the right front panel 123. When the right front panel 123 enters the right opening 38, the four second step surfaces 126 abut against the inner side walls of the four bends at the right opening 38, and the front side wall of the bend abuts against the rear side wall of the right front panel 123, ensuring the size of the right opening 38 and limiting the bend at the right opening 38.

[0046] In this embodiment, the right panel 24 of the existing cabinet 2 includes a first panel 241 and a second panel 242 arranged in the front-to-back direction. The first panel 241 and the second panel 242 are arranged parallel in the left-to-right direction, and the first panel 241 is located to the right of the second panel 242. The front right side wall of the upper panel 21 protrudes to the right beyond the rear right side wall of the upper panel 21, and the front right side wall of the lower panel 22 protrudes to the right beyond the rear right side wall of the lower panel 22. The front part of the lower panel 22 is integrally connected to the lower side wall of the first panel 241, and a fifth right-angle bend 30 is formed between the two. The rear right side wall of the lower panel 22 is integrally connected to the lower side wall of the second panel 242, and a sixth right-angle bend 31 is formed between the two. The fifth right-angle bend 30 and the sixth right-angle bend 31 constitute the third right-angle bend 28. Correspondingly, the first connecting plate 32 includes a third connecting plate 34 and a fourth connecting plate 35. The third connecting plate 34 is connected to the upper side wall of the first panel 241 by a right-angle bend, and the third connecting plate 34 is located in the middle of the upper side wall of the first panel 241. The fourth connecting plate 35 is connected to the upper side wall of the second panel 242 by a right-angle bend. The third connecting plate 34 and the fourth connecting plate 35 are welded to the front and rear inner side walls of the upper panel 21, respectively, thereby welding the right side wall of the upper panel 21 and the upper side wall of the right panel 24, forming a protruding cavity in the front right part of the cabinet 2 for installing a waterproof connector. The waterproof connector is used for wiring. Correspondingly, in this embodiment, there are multiple right fixing components 13, specifically three. One right fixing component 13 is located on the front right side of the cabinet 2, where the lower side wall of the first protrusion 133 on the upper part of the right fixing plate 132 presses against the upper side wall of the first panel 241. The other two right fixing components 13 are located on the rear right side of the cabinet 2, where the first protrusion 133 on the upper part of the right fixing plate 132 presses against the bend between the second panel 242 and the third connecting plate 34, i.e., the sixth right-angle bend 31, thereby fixing the first panel 241 and the second panel 242 that make up the right panel 24 and ensuring the perpendicularity of the first panel 241 and the second panel 242.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
