Description

Technical Field

[0001] This application relates to the field of electrical distribution box manufacturing equipment technology, and in particular to an assembly device for electrical distribution boxes. Background Technology

[0002] Distribution boxes, as key components in power systems used for distributing electrical energy and protecting circuit equipment, are widely used in various fields such as construction, industrial production, and municipal engineering. In the manufacturing process of distribution boxes, assembly is one of the core procedures, mainly involving the splicing and fixing of the distribution box base, side panels, top cover, and internal electrical components (such as circuit breakers and terminals).

[0003] Currently, the assembly of distribution boxes typically employs a traditional fixed workbench model. Operators place the distribution box base on a horizontal, fixed workbench and then sequentially weld, bolt, or rivet the side panels, followed by the installation of electrical components. However, this traditional assembly method has several technical drawbacks: 1. Limited operating angle and high labor intensity: Because the workbench is fixed, the distribution box base and the assembled box body remain horizontal. When welding or wiring is required on the sides, bottom, or top of the box, operators must frequently bend over, turn sideways, or tilt their heads back. Prolonged work can easily lead to occupational injuries such as back pain and neck fatigue, and it is difficult to guarantee operational accuracy. Especially for larger and heavier distribution boxes, operators need to constantly move around the box, further increasing labor intensity. 2. Insufficient equipment mobility and poor adaptability: Traditional assembly workbenches are mostly fixed structures and cannot be adjusted according to the layout of the production site. When it is necessary to move distribution boxes between different workstations or adjust the assembly area, auxiliary equipment such as forklifts and cranes are required, making the operation cumbersome and inefficient. Utility Model Content

[0004] This utility model addresses the aforementioned problems in the existing technology by providing an assembly device for a distribution box.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] An assembly device for a distribution box includes a support base, with casters equipped with braking functions installed at the four corners of the bottom of the support base; support columns are provided on the left and right sides of the upper surface of the support base, and a support frame for placing the distribution box base is rotatably connected between the tops of two support columns, and a limiting frame is installed on each of the four inner sides of the support frame; a support plate extending from the side wall of the limiting frame is provided at the bottom of the limiting frame facing the center of the support frame, and a clamping assembly is provided at the bottom of the support plate, which can clamp the distribution box base into the support frame;

[0007] A limiting mechanism is provided between the support column and the side wall of the support frame, which is used to lock the support frame when it rotates to the corresponding angle.

[0008] Preferably, the limiting mechanism includes a mounting plate fixedly connected to the side wall of the support column near the support frame. The mounting plate is circular and its axis coincides with the rotation axis of the support frame. A positioning plate corresponding to the mounting plate is fixedly connected to the side wall of the support frame near the support column. The positioning plate is circular and coaxial with the mounting plate. A ring of positioning holes is uniformly arranged around the side wall of the positioning plate around its axis. A positioning pin is slidably inserted through the mounting plate in a direction perpendicular to the surface of the positioning plate. One end of the positioning pin can be inserted into any one of the positioning holes, and the other end extends out of the mounting plate and is installed on the support base.

[0009] Preferably, a rotating shaft is coaxially fixed to the side wall of the positioning plate, a bearing seat is installed on the top of the support column, and one end of the rotating shaft passes through the mounting plate and is rotatably connected to the bearing seat.

[0010] Preferably, the support base has a U-shaped structure, with a limiting plate fixedly connected inside. The sidewalls of the positioning pin are respectively provided with a first protrusion and a second protrusion. The sidewalls of the limiting plate and the mounting plate are both provided with through holes for the positioning pin to slide. The diameters of the first protrusion and the second protrusion are larger than the diameter of the through holes. The first protrusion is located between the inner side of the support base and the sidewall of the limiting plate, and the second protrusion is located between the sidewall of the limiting plate and the sidewall of the mounting plate. A return spring is sleeved on the outer side of the positioning pin. One end of the return spring abuts against the sidewall of the limiting plate, and the other end abuts against the sidewall of the second protrusion. The return spring always has a tendency to push the positioning pin into the positioning hole.

[0011] Preferably, the clamping assembly includes an L-shaped clamping plate, one end of which is fixedly connected to the lower surface of the support plate, and the other end of which faces the center of the support frame and extends upward to a position higher than the upper surface of the support plate. The upper part of the L-shaped clamping plate is threaded with a clamping bolt, and the distribution box base is pressed between the limit frame and the clamping bolt by tightening the clamping bolt.

[0012] Preferably, the clamping bolt has an anti-slip rubber head at one end facing the limiting frame.

[0013] Preferably, a reinforcing rod is provided between the support column and the side wall of the support base.

[0014] Preferably, the support base has a counterweight cavity with a top opening in the middle, and a counterweight block is placed in the counterweight cavity.

[0015] In summary, compared with the prior art, the present invention has the following beneficial technical effects:

[0016] (1) This utility model achieves locking of the support frame at multiple angles by rotating the support frame and the support column, and with the help of the limiting mechanism. Operators do not need to frequently adjust their own posture to assemble different sides of the distribution box, which effectively reduces bending over, turning to the side and other actions, and reduces labor intensity. At the same time, the angle adjustment process is simple and quick, without the need for auxiliary equipment, which significantly improves assembly efficiency.

[0017] (2) In this utility model, the limiting frame inside the support frame can initially position the distribution box base and limit its horizontal displacement; the clamping assembly can firmly clamp the base through the cooperation of the clamping bolt and the limiting, preventing the base from shaking or shifting during assembly; the setting of the anti-slip rubber head further enhances the reliability of clamping, avoids the base from sliding or surface damage, and ensures that the assembly accuracy meets the requirements.

[0018] (3) The universal wheel with braking function in this utility model allows the device to move flexibly according to production needs without relying on auxiliary equipment, which improves the adaptability of the device; the counterweight block in the support base can adjust the center of gravity of the device and prevent the device from tipping over; the reinforcing rod enhances the structural strength of the support column and avoids deformation of the support column.

Detailed Implementation

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0027] like Figure 1 , 2 As shown, this utility model discloses a technical solution: an assembly device for a distribution box, including a support base 1. Each of the four corners of the bottom of the support base 1 is equipped with a caster wheel 2 with a braking function. The caster wheel 2 allows for flexible movement of the device, and the braking function locks the device after it reaches the target position, preventing slippage during assembly. The caster wheel 2 is commercially available, and its specific structure will not be described here. Vertical support columns 3 are welded or bolted to the center of both sides of the upper surface of the support base 1. A support frame 4 for placing the distribution box base is rotatably connected between the tops of the two support columns 3. The support frame 4 can rotate around the top of the support columns 3, thereby adjusting the distribution box base to a suitable assembly angle. The four inner sides of the support frame 4 are welded or bolted... The bolted connection includes a limiting frame 5, which is used to initially position the distribution box base and limit its horizontal displacement within the support frame 4. A support plate 6, extending from the side wall of the limiting frame 5, is welded or bolted to the bottom of the limiting frame 5 facing the center of the support frame 4. The support plate 6 bears the weight of the distribution box base. A clamping assembly is located at the bottom of the support plate 6, which clamps the distribution box base within the support frame 4, ensuring stability during assembly. The dimensions of the support frame 4 and the limiting frame 5 can be customized according to the actual dimensions of the distribution box. A limiting mechanism is provided between the support column 3 and the side wall of the support frame 4. This limiting mechanism locks the support frame 4 when it rotates to a corresponding angle, preventing accidental rotation during assembly.

[0028] Specifically, such as Figure 3 As shown, the limiting mechanism includes a mounting plate 7 welded or bolted to the side wall of the support column 3 near the support frame 4. The mounting plate 7 is circular and its axis coincides with the rotation axis of the support frame 4. A positioning plate 8 corresponding to the mounting plate 7 is welded or bolted to the side wall of the support frame 4 near the support column 3. The positioning plate 8 is circular and coaxial with the mounting plate 7. A ring of positioning holes 9 is evenly arranged around the side wall of the positioning plate 8 around its axis. A positioning pin 10 is slidably inserted on the mounting plate 7 in a direction perpendicular to the surface of the positioning plate 8. One end of the positioning pin 10 can be inserted into any positioning hole 9, and the other end extends out of the mounting plate 7 and is installed on the support base 11. By cooperating with different positioning holes 9, the support frame 4 can be locked at different rotation angles.

[0029] Specifically, a rotating shaft 12 is coaxially welded to the side wall of the positioning plate 8, and a bearing seat 13 is fixedly installed on the top of the support column 3 by bolts. One end of the rotating shaft 12 passes through the mounting plate 7 and is rotatably connected to the bearing seat 13. The cooperation between the rotating shaft 12 and the bearing seat 13 ensures the smoothness of the rotation process of the support frame 4 and reduces rotational friction.

[0030] Specifically, such as Figure 5 , 6 As shown, the support base 11 has a U-shaped structure and is fixedly installed on the outside of the mounting plate 7 by bolts. A limiting plate 14 is fixedly connected inside the support base 11 by bolts. The sidewalls of the positioning pin 10 are respectively fitted with a first protrusion 15 and a second protrusion 16 via pins. Both the limiting plate 14 and the sidewalls of the mounting plate 7 are provided with through holes 17 for the positioning pin 10 to slide. The diameters of the first protrusion 15 and the second protrusion 16 are larger than the diameter of the through holes 17. The first protrusion 15 is located inside the support base 11 and on the sidewalls of the limiting plate 14. Between the walls, the second protrusion 16 is located between the side wall of the limiting plate 14 and the side wall of the mounting plate 7. A return spring 18 is sleeved on the outside of the positioning pin 10. One end of the return spring 18 abuts against the side wall of the limiting plate 14, and the other end abuts against the side wall of the second protrusion 16. The return spring 18 always has the tendency to push the positioning pin 10 into the positioning hole 9. The setting of the return spring 18 can ensure that the positioning pin 10 always maintains the cooperation with the positioning hole 9 in the non-human operation state, thereby improving the reliability of the limiting mechanism.

[0031] Specifically, such as Figure 4 As shown, the clamping assembly includes an L-shaped clamping plate 19. One end of the L-shaped clamping plate 19 is welded or bolted to the lower surface of the support plate 6. The other end of the L-shaped clamping plate 19 faces the center of the support frame 4 and extends upward to a position higher than the upper surface of the support plate 6. The upper part of the L-shaped clamping plate 19 is threaded with a clamping bolt 20. By tightening the clamping bolt 20, the base of the distribution box is pressed between the limit frame 5 and the clamping bolt 20.

[0032] Specifically, an anti-slip rubber head 21 is attached to one end of the clamping bolt 20 facing the limiting frame 5. The anti-slip rubber head 21 can increase the friction between the clamping bolt 20 and the distribution box base to prevent the base from sliding after clamping. On the other hand, it can prevent the clamping bolt 20 from directly contacting the base and causing damage to the base surface.

[0033] Specifically, the front and rear side walls of the support column 3 are welded or bolted to the upper surface of the support base 1 with reinforcing rods 22. The reinforcing rods 22 adopt a triangular stable structure design, which can enhance the connection strength between the support column 3 and the support base 1 and prevent the support column 3 from tilting or deforming under the gravity of the support frame 4 and the distribution box.

[0034] Specifically, the support base 1 has a counterweight cavity 23 with an open top in the middle, and a counterweight block is placed in the counterweight cavity 23. By adding or removing counterweight blocks in the counterweight cavity 23, the overall center of gravity of the device can be adjusted to prevent the device from tipping over due to the distribution box on top, thereby improving the stability of the device.

[0035] When using this distribution box assembly device, first, according to the weight of the distribution box base, place an appropriate amount of counterweight in the counterweight cavity 23 of the support base 1 to ensure the overall stability of the device; then, move the device to the assembly station using the universal wheels 2 with braking function, and activate the braking function of the universal wheels 2 to lock the device position.

[0036] Place the distribution box base on the support plate 6 inside the support frame 4, so that the four sides of the base fit against the limiting frame 5 inside the support frame 4 to achieve initial positioning; then tighten the clamping bolts 20 on the L-shaped clamping plate 19 until the anti-slip rubber head 21 at the end of the clamping bolt 20 is in close contact with the base, and firmly clamp the base between the limiting frame 5 and the clamping bolt 20 to complete the fixing of the base.

[0037] When the assembly angle needs to be adjusted, the operator pulls the positioning pin 10 outward through the first protrusion 15. The positioning pin 10 drives the second protrusion 16 to compress the return spring 18. At the same time, one end of the positioning pin 10 disengages from the positioning hole 9 of the positioning plate 8. At this time, the support frame 4 is rotated, and the support frame 4 drives the positioning plate 8 to rotate synchronously around the rotation axis 12. After the support frame 4 rotates to the target angle, the positioning pin 10 is released. Under the action of the elastic force, the return spring 18 pushes the second protrusion 16 to move, thereby driving the positioning pin 10 to re-insert into the positioning hole 9 of the corresponding position of the positioning plate 8, completing the angle locking of the support frame 4. The operator can then perform assembly operations such as side wall panel welding and electrical component installation at this angle.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
