Description

Technical Field

[0001] This utility model relates to the field of shell processing technology, specifically to a positioning fixture for a cable branch box shell. Background Technology

[0002] The cable distribution box housing is the core structural component of the cable distribution box. As the "outer garment" protecting the internal power distribution components, it not only needs sufficient mechanical strength to withstand the impact of the external environment, but also needs to meet the performance requirements of sealing and protection to ensure the safe and stable operation of the power grid distribution system. Its manufacturing process typically uses stainless steel plates, aluminum alloy plates, or high-quality cold-rolled steel plates as raw materials. After cutting, the flat plates are processed into a box structure with a specific shape through a bending process. The bending process is a key step in the shell forming, requiring precise control of the bending angle and dimensions to ensure a tight fit between the various panels of the box, laying the foundation for subsequent welding, surface treatment, and other processes.

[0003] Based on the above, the inventors have discovered the following problems: In the current bending process of cable branch box housings, traditional processes typically require bending one side of the sheet metal first, followed by manual adjustment of the sheet metal position by the operator to align the unbent side with the bending groove of the bending equipment before bending the next side. Because the manual adjustment process lacks a precise positioning mechanism, the operator relies entirely on experience to judge the placement of the sheet metal, making it difficult to ensure that the relative distance between the sheet metal and the bending groove is consistent after each adjustment. This results in deviations in the bending dimensions of each side of the box after bending, ultimately causing uneven thickness of the cable branch box housing. This not only affects the structural stability and sealing of the housing but also makes component installation difficult during subsequent assembly, reducing overall product quality and production efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a positioning tool for the cable branch box housing, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for cable branch box housing to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A positioning fixture for a cable branch box housing includes a base assembly and a positioning assembly. The base assembly includes a base with an installation groove at one end and a vertical rod slidably mounted on the top surface of the base. The positioning assembly includes a connecting strip slidably mounted inside the installation groove. A fixing seat is mounted on one end of the connecting strip, and a bidirectional electric push rod is mounted inside the fixing seat. Both telescopic ends of the bidirectional electric push rod are mounted with connecting seats, and positioning rods are mounted on the top surfaces of both connecting seats. A square notch is provided on the opposite side of the outer wall of the vertical rod and the two positioning rods.

[0007] Furthermore, a rack is installed on the top surface of the connecting strip, and a plurality of oblique teeth are spaced apart on the rack. An elastic strip is installed on the inner top surface of one end of the mounting groove, and a fixing tooth is installed at the bottom end of the elastic strip. The fixing tooth engages with the oblique teeth on the rack.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, since the fixed teeth engage with the helical teeth on the rack, when the connecting strip is pulled outward, the helical teeth on the rack are restricted by the fixed teeth and cannot be pulled outward, thus ensuring the stability of the position of the fixed seat and the positioning rod, and thus ensuring the accuracy of the housing positioning.

[0009] Furthermore, the elastic strip is U-shaped, and an arc-shaped actuating head is installed at one end of the elastic strip near the side wall of the rack. The elastic strip is made of spring steel.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the U-shaped elastic strip has good deformation capacity. When the arc-shaped actuating head is lifted, the side wall with the fixed teeth can naturally contract, causing the fixed teeth to separate from the rack's helical teeth. After being released, it can quickly reset, ensuring the reliability of the engagement. The arc-shaped actuating head makes it easy for operators to manually lift the side wall with the fixed teeth, reducing the difficulty of operation. The elastic strip made of spring steel has high strength, high elastic limit and fatigue resistance, and can withstand multiple deformations without being easily damaged, extending the service life of the elastic strip. At the same time, it ensures the stable engagement force of the fixed teeth and the helical teeth, avoiding locking failure due to elastic decay.

[0011] Furthermore, a limiting groove is provided on the inner bottom surface of the mounting groove, and a limiting block is slidably connected inside the limiting groove. The limiting block is installed on the bottom surface of the end of the connecting strip away from the fixed seat.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the limiting block and the limiting groove allows the connecting strip to slide horizontally only along the direction of the limiting groove, avoiding the connecting strip from shifting or falling off during the sliding process, and ensuring the accuracy of the positioning rod adjustment direction.

[0013] Furthermore, the top surface of the base is provided with an elongated groove, an electric slide rail is installed inside the elongated groove, an electric slider is slidably connected to the outside of the electric slide rail, and the top surface of the electric slider is fixedly connected to the bottom surface of the vertical rod.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the electric slide rail can drive the electric slider to move the vertical rod smoothly along the long groove, and with the help of two positioning rods, three-point positioning of the plate is achieved, and the positioned plate covers the bending groove on the top surface of the base; the inner wall of the square notch on the positioning rod fits with the side wall of the plate, and the distance between the positioning rod and the bending groove is the thickness of the shell after the plate is bent.

[0015] Furthermore, the long groove is located on the vertical symmetry line of the base, and the long groove and the mounting groove are arranged sequentially from top to bottom.

[0016] The beneficial effects of adopting the above-mentioned further scheme are that the long groove is located on the vertical symmetry line, so that the adjustment trajectory of the vertical rod is aligned with the center of the base, ensuring that the positioning force of the vertical rod on the shell is evenly distributed and avoiding shell displacement due to force imbalance; the long groove and the mounting groove are set in layers from top to bottom, which makes full use of the internal space of the base and avoids mutual interference between the components during movement.

[0017] Furthermore, the bottom surface of several of the square notches is flush with the top surface of the base, and the top surface of the base is provided with a bending groove on the side away from the vertical rod, and the included angle of the bending groove is 90°.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the bottom surface of the square notch is flush with the top surface of the base, ensuring that the edge of the shell can fit tightly with the notch after the shell is placed on the top surface of the base; the 90° bending groove can be used with the bending head to bend the edge of the plate in subsequent bending operations, and the shell is formed after the four sides of the plate are bent (the position of the positioning rod remains unchanged during the bending process, the distance between the positioning rod and the bending groove remains unchanged, and the thickness of the shell is consistent after the four sides are bent).

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The cable branch box housing positioning fixture has a bidirectional electric push rod that can drive two positioning rods to move synchronously in opposite directions, adapting to plates of different lengths; the square notch on the opposite side of the vertical rod and the two positioning rods can precisely fit with the edge of the housing, forming a three-point positioning, effectively limiting the displacement of the housing and ensuring stable positioning; because the fixed teeth engage with the oblique teeth on the rack, when the connecting strip is pulled outward, the oblique teeth on the rack are restricted by the fixed teeth and cannot be pulled outward. It is necessary to use the arc-shaped actuating head to lift it upward, so that the side wall of the U-shaped elastic strip with the fixed teeth is contracted until the fixed teeth separate from the oblique teeth on the rack, and then the connecting strip can be pulled outward. When it is pulled to a certain length, the arc-shaped actuating head is released to reset the side wall of the U-shaped elastic strip, and the fixed teeth re-engage with the oblique teeth on the rack, limiting the adjusted connecting strip, fixed seat, positioning rod and other components. At this time, the distance between the positioning rod and the bending groove is adjusted, thereby realizing the adjustment of the housing thickness during the subsequent bending operation.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a positioning fixture for a cable branch box housing, including a base assembly 1 and a positioning assembly 2. The base assembly 1 includes a base 11, with an installation groove 17 inside one end of the base 11, and a vertical rod 16 slidably mounted on the top surface of the base 11. The positioning assembly 2 includes a connecting strip 21, which is slidably mounted inside the installation groove 17. A fixing seat 22 is mounted on one end of the connecting strip 21, and a bidirectional electric push rod 23 is mounted inside the fixing seat 22. Both telescopic ends of the bidirectional electric push rod 23 are mounted with connecting seats 24. Positioning rods 25 are installed on the top surface of each component; square notches 3 are provided on the opposite sides of the outer walls of the vertical rod 16 and the two positioning rods 25; a rack 26 is installed on the top surface of the connecting strip 21, and several oblique teeth are provided at intervals on the rack 26; an elastic strip 27 is installed on the inner top surface of one end of the mounting groove 17; a fixing tooth 28 is installed at the bottom end of the elastic strip 27, and the fixing tooth 28 engages with the oblique teeth on the rack 26; the elastic strip 27 is U-shaped; an arc-shaped actuating head is installed at the end of the elastic strip 27 near the side wall of the rack 26; the elastic strip 27 is made of spring steel; and a limit groove 29 is provided on the inner bottom surface of the mounting groove 17. The limiting groove 29 has a sliding connection to a limiting block 210, which is installed on the bottom surface of the connecting strip 21 at the end away from the fixed seat 22. When it is necessary to process cable branch box housings of different thicknesses, the arc-shaped actuating head on the elastic strip 27 is manually lifted upwards, causing the side wall of the U-shaped elastic strip 27 with the fixing teeth 28 to retract. The fixing teeth 28 separate from the oblique teeth on the rack 26. At this time, the connecting strip 21 is pulled outwards, and the connecting strip 21 slides in the mounting groove 17. The limiting block 210 at the bottom slides synchronously along the limiting groove 29, ensuring that the sliding direction of the connecting strip 21 is accurate. When the distance between the positioning rod 25 and the bending groove 12 on the top surface of the base 11 reaches the value corresponding to the required shell thickness, the arc-shaped actuating head is released, and the side wall of the U-shaped elastic strip 27 is reset under the elastic action of its own spring steel material. The fixing tooth 28 re-engages with the helical tooth on the rack 26, limiting the connection bar 21 and other components. The bidirectional electric push rod 23 is used to drive the two positioning rods 25 to move synchronously in opposite directions, adapting to plates of different lengths. The components and working principle of the bidirectional electric push rod 23 are disclosed in the bidirectional electric push rod of patent publication number CN220382871U.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a long groove 13 is provided on the top surface of the base 11, an electric slide rail 14 is installed inside the long groove 13, and an electric slider 15 is slidably connected to the outside of the electric slide rail 14. The top surface of the electric slider 15 is fixedly connected to the bottom surface of the vertical rod 16. The long groove 13 is located on the vertical symmetry line of the base 11. The long groove 13 and the mounting groove 17 are arranged sequentially from top to bottom. The bottom surfaces of several square notches 3 are flush with the top surface of the base 11. A bending groove 12 is provided on the top surface of the base 11 on the side away from the vertical rod 16, and the included angle of the bending groove 12 is 90°. The electric slide rail 14 can drive the electric slider 15. 5 drives the vertical rod 16 to move smoothly along the long groove 13, and cooperates with the two positioning rods 25 to achieve three-point positioning of the plate. The positioned plate covers the bending groove 12 on the top surface of the base 11. The inner wall of the square notch 3 on the positioning rod 25 fits with the side wall of the plate. The distance between the positioning rod 25 and the bending groove 12 is the thickness of the shell after the plate is bent. The 90° bending groove 12 can cooperate with the bending head to bend the edge of the plate in the subsequent bending operation. When the plate is bent on all four sides to form the shell, the position of the positioning rod 25 remains unchanged during the bending process, the distance between the positioning rod 25 and the bending groove 12 remains unchanged, and the thickness of the shell is consistent after the four sides are bent.

[0026] Specifically, the working principle of this cable branch box housing positioning fixture is as follows: During use, the plate is placed on the base 11. To process a cable branch box housing of a specific thickness, the arc-shaped actuating head on the elastic strip 27 is manually lifted upwards, causing the side wall of the U-shaped elastic strip 27 with the fixing teeth 28 to contract, separating the fixing teeth 28 from the oblique teeth on the rack 26. Next, the connecting strip 21 is pulled outwards, sliding within the mounting groove 17. The bottom limiting block 210 slides synchronously along the limiting groove 29, ensuring accurate sliding direction of the connecting strip 21. When the distance between the positioning rod 25 and the bending groove 12 on the top surface of the base 11 reaches the value corresponding to the required housing thickness, the arc-shaped actuating head is released. The side wall of the U-shaped elastic strip 27 returns to its original position under the elasticity of its own spring steel material, and the fixing teeth 28 re-engage with the oblique teeth on the rack 26, limiting the movement of components such as the connecting strip 21. Then, the electric slide rail 14 drives the electric slider 15, which in turn moves the vertical rod 16 along the long groove 13 to a suitable position. Next, the bidirectional electric push rod 23 is activated, and its two telescopic ends drive the two connecting seats 24 and the positioning rod 25 to move synchronously. This causes the square notches 3 on the vertical rod 16 and the two positioning rods 25 to fit against the edges of the material to be processed, achieving three-point positioning of the material. The positioned material covers the bending groove 12 on the top surface of the base 11, and the inner wall of the square notch 3 on the positioning rod 25 fits against the side wall of the material. Finally, using an external bending device and the 90° bending groove 12 on the top surface of the base 11, the edges of the material are bent. During the bending process, the position of the positioning rod 25 remains unchanged, and the distance between the positioning rod 25 and the bending groove 12 remains constant. After the four sides of the material are bent, a cable branch box housing of uniform thickness is formed.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
