Description

Technical Field

[0001] This utility model belongs to the field of steel welding technology, specifically a steel welding device for the base of a power distribution cabinet. Background Technology

[0002] In the manufacturing process of distribution cabinets, the welding of the base steel is a crucial step in ensuring the overall structural stability and installation accuracy of the distribution cabinet. The base of the distribution cabinet is usually composed of four steel sections spliced ​​together in a U-shape. The dimensional accuracy of this structure, the size of the splicing gaps, and the perpendicularity between the steel sections directly affect the subsequent assembly quality and safety of the distribution cabinet. Therefore, extremely high requirements are placed on the positioning and fixing of the steel sections during the welding process.

[0003] However, in current industry practices, welding of distribution cabinet base steel sections typically involves repeatedly measuring and adjusting the position of the steel sections using tools such as tape measures and right-angle rulers to ensure that the four steel sections can be joined into a U-shape that meets dimensional requirements. During this process, the steel sections lack a stable fixing mechanism and rely solely on the operator's hand or simple support blocks. This makes them highly susceptible to displacement due to hand tremors, external impacts, and other factors. This not only requires repeated adjustments, severely impacting positioning accuracy, but also significantly extends preparation time and reduces overall welding efficiency. To address these issues, we provide a welding device for distribution cabinet base steel sections. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a welding device for the base steel of a power distribution cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for the base steel of a power distribution cabinet, comprising a base, a fixed seat fixedly connected to the middle of the base, two bidirectional lead screws arranged in an alternating vertical cross shape rotatably connected to the fixed seat, two motors for driving the two bidirectional lead screws to rotate respectively on the base, U-shaped frames threaded to both ends of the two bidirectional lead screws, and the bottom surface of the U-shaped frames sliding on the base, an L-shaped seat fixedly connected to the top of each U-shaped frame, a clamping mechanism for clamping the steel profile on each L-shaped seat, and a linkage mechanism for releasing each clamping mechanism in the middle of the base.

[0006] Preferably, the clamping mechanism includes a clamping plate movably mounted on an L-shaped seat. The L-shaped seat is provided with a guide mechanism for the clamping plate to automatically reset and slide. An installation cavity is provided in the middle of the L-shaped seat. A sliding plate is elastically slidably mounted on the inner wall of the installation cavity. An equally spaced oblique slot is provided on the upper surface of the sliding plate. An oblique locking block is fixedly connected to the bottom surface of the clamping plate and engages in the corresponding oblique slot. A T-shaped rod is fixedly connected to the bottom surface of the sliding plate and slides through to the bottom of the L-shaped seat.

[0007] Preferably, the guiding mechanism includes two guide grooves, both of which are formed on an L-shaped seat. Two sliders are fixedly connected to the bottom end of the clamping plate. Guide rods are fixedly connected to the inner walls of the two guide grooves. The two sliders are elastically slidably sleeved on the two guide rods respectively.

[0008] Preferably, a second compression spring is fitted on the surface of each of the two guide rods, and the two ends of the second compression spring are respectively fixed to the inner wall of the guide groove and the surface of the slider.

[0009] Preferably, a plurality of first compression springs are fixedly connected to the bottom surface of the sliding plate, and the bottom ends of the first compression springs are fixedly connected to the inner bottom wall of the mounting cavity.

[0010] Preferably, the linkage mechanism includes a bracket, which is fixedly connected to the middle of the base. A cylinder is installed at the top of the bracket, and a cross plate is fixedly connected to the telescopic end of the cylinder. Two actuating plates are fixedly connected to each end of the cross plate. Each pair of actuating plates slides on the surface of a corresponding T-shaped rod, and the actuating plates are higher than the bottom end of the T-shaped rod.

[0011] Preferably, both motors are fixed on the base, and the telescopic ends of the two motors are respectively connected to one end of the two bidirectional lead screws, with the ends of the two bidirectional lead screws away from the corresponding motors being rotatably connected to the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the coordinated arrangement of a base, a fixed seat, a bidirectional lead screw, a motor, a U-shaped frame, an L-shaped seat, a clamping mechanism, and a linkage mechanism, allows four steel profiles to be placed on four L-shaped seats and fixed by corresponding clamping mechanisms. Then, the operation of two motors drives two bidirectional lead screws to rotate, aligning the four steel profiles in a U-shape. Personnel then use handheld welding equipment to weld them. After welding, the operation of a cylinder controls the downward movement of a cross plate, which in turn pushes the bottom of the corresponding T-shaped rod downwards, causing each clamping plate to automatically reset and release the steel profiles. Finally, the welded steel profiles can be removed. This operation is more convenient, eliminating the need for repeated adjustments during processing, ensuring the positioning accuracy of the steel profile welding, reducing preparation time, and improving overall welding efficiency.

[0015] 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.

[0016] like Figure 1-6As shown, this embodiment proposes a welding device for the steel profile of a power distribution cabinet base, including a base 1. A fixed seat 5 is fixedly connected to the middle of the base 1. Two bidirectional lead screws 4 arranged in a cross shape are rotatably connected to the fixed seat 5, so that the two bidirectional lead screws 4 do not affect each other when rotating. Two motors 6 are provided on the base 1 to drive the two bidirectional lead screws 4 to rotate respectively. The operation of the corresponding motors 6 can drive the bidirectional lead screws 4 to rotate. Both ends of the two bidirectional lead screws 4 are threaded with U-shaped frames 3, and the bottom surface of the U-shaped frames 3 slides on the base 1. When the bidirectional lead screws 4 rotate, they can drive the corresponding two U-shaped frames 3 to move relative to each other on the base 1. Each U-shaped frame 3 is fixedly connected to the top of an L-shaped seat 7, and each L-shaped seat 7 is provided with a clamping device for the steel profile. The clamping mechanism has a linkage mechanism in the middle of the base 1 for releasing each clamping mechanism. With the above structure, four steel sections can be placed on four L-shaped seats 7 and fixed by the corresponding clamping mechanisms. Then, the operation of the motor 6 drives the corresponding bidirectional lead screw 4 to rotate, so that the four steel sections are joined together in a U-shape. Finally, the four steel sections can be welded by personnel using welding equipment. After the four steel sections are welded together, the clamping of each steel section can be released by the linkage mechanism, and the personnel can directly remove them. The steel sections are kept stable throughout the welding process. The machinery, parts and equipment in this device are all conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0017] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the clamping mechanism includes a clamping plate 12, which is movably mounted on an L-shaped seat 7. The L-shaped seat 7 is equipped with a guide mechanism for the clamping plate 12 to automatically reset and slide. A mounting cavity 19 is formed in the middle of the L-shaped seat 7. A sliding plate 13 is elastically slidably mounted on the inner wall of the mounting cavity 19. The upper surface of the sliding plate 13 has evenly spaced oblique slots 14. An oblique locking block 21 is fixedly connected to the bottom surface of the clamping plate 12, and the oblique locking block 21 engages with the corresponding oblique slot 14. A T-shaped rod 1 is fixedly connected to the bottom surface of the sliding plate 13. 8. The T-shaped rod 18 slides through to the bottom of the L-shaped seat 7. With the above structure, when the steel section is placed on the L-shaped seat 7, the operator can directly push the clamping plate 12 to clamp the steel section between the clamping plate 12 and the L-shaped seat 7, making the operation more convenient. When the operator needs to release the clamping plate 12 from the steel section, he only needs to pull the T-shaped rod 18 down and drive the sliding plate 13 to move down, so that the inclined clamping block 21 is away from the inclined clamping groove 14. Then the operator can adjust the position of the steel section on the L-shaped seat 7 or take it out.

[0018] like Figures 3 to 5As shown, the guiding mechanism includes two guide grooves 15, both of which are formed on the L-shaped seat 7. Two sliders 2 are fixedly connected to the bottom end of the clamping plate 12. Guide rods 16 are fixedly connected to the inner walls of the two guide grooves 15. The two sliders 2 are elastically slidably sleeved on the two guide rods 16 respectively. With the above structure, when the clamping plate 12 is pushed, the two sliders 2 will slide on the two guide rods 16 respectively, thereby ensuring the sliding stability of the clamping plate 12 on the L-shaped seat 7.

[0019] like Figure 3 and Figure 4 As shown, the surfaces of the two guide rods 16 are each fitted with a second compression spring 17, and the two ends of the second compression spring 17 are respectively fixed to the inner wall of the guide groove 15 and the surface of the slider 2. With the above structure, when the sliding plate 13 moves away from the clamping plate 12, the clamping plate 12 will automatically reset under the elastic force of the second compression spring 17, so that the clamping plate 12 does not need to be manually pulled to reset, making it more convenient to use.

[0020] like Figure 4 and Figure 6 As shown, several first compression springs 20 are fixedly connected to the bottom surface of the sliding plate 13, and the bottom end of the first compression spring 20 is fixedly connected to the inner bottom wall of the mounting cavity 19. With the above structure, when the clamping plate 12 slides on the L-shaped seat 7, the inclined locking block 21 will slide sequentially in the inclined locking groove 14, causing the sliding plate 13 to move up and down in the mounting cavity 19 and compress the first compression springs 20 until the clamping plate 12 stops moving. Under the elastic force of the first compression spring 20, the inclined locking groove 14 ensures the restriction of the inclined locking block 21, thereby preventing the clamping plate 12 from moving arbitrarily.

[0021] like Figure 1 and Figure 2 As shown, the linkage mechanism includes a bracket 8, which is fixedly connected to the middle of the base 1. A cylinder 9 is installed at the top of the bracket 8. A cross plate 10 is fixedly connected to the telescopic end of the cylinder 9. Two actuating plates 11 are fixedly connected to each end of the cross plate 10. Each pair of actuating plates 11 slides on the surface of the corresponding T-shaped rod 18, and the actuating plates 11 are higher than the bottom end of the T-shaped rod 18. With the above structure, when it is necessary to release the clamping plate 12 from the steel profile, the operation of the cylinder 9 is used to control the cross plate 10 to move downward, thereby causing each set of actuating plates 11 to push the bottom end of the corresponding T-shaped rod 18 to move downward, and each clamping plate 12 will automatically reset, thereby removing the welded steel profile.

[0022] like Figure 1 and Figure 2As shown, both motors 6 are fixed on the base 1, and the telescopic ends of the two motors 6 are respectively connected to one end of the two bidirectional lead screws 4. The ends of the two bidirectional lead screws 4 away from the corresponding motors 6 are rotatably connected to the base 1. With the above structure, the stability of the two bidirectional lead screws 4 during rotation can be guaranteed, and deformation of the bidirectional lead screws 4 can be avoided.

[0023] The working principle and usage process of this utility model are as follows: When welding of structural steel is required, firstly, four structural steel sections are placed on four L-shaped seats 7 respectively, and the corresponding clamping plates 12 are pushed to fix the structural steel sections. Then, the operation of two motors 6 drives two bidirectional lead screws 4 to rotate, thereby adjusting the contact between the structural steel sections to form a U-shape. Then, the personnel can use the welding equipment to perform welding. After the structural steel sections are welded, the operation of the cylinder 9 controls the cross plate 10 to move downward, thereby causing each set of actuating plates 11 to push the bottom end of the corresponding T-shaped rod 18 downward. Then, each clamping plate 12 will automatically reset, thereby releasing the clamping of the structural steel sections. Finally, the personnel can remove the welded structural steel sections, making the operation more convenient.
