Description
Technical Field
[0001] This utility model belongs to the field of conductive busbar processing technology, and in particular relates to a drilling and milling device for conductive busbars. Background Technology
[0002] As a core component of power transmission, busbars are widely used in distribution cabinets, industrial equipment and new energy fields. U-shaped busbars have advantages in cross-sectional structure, combining high current carrying capacity, heat dissipation and mechanical strength. However, the processing requires precise completion of processes such as drilling and milling to meet the requirements of installation, insulation separation and electrical connection.
[0003] Traditional processing equipment has significant limitations when dealing with U-shaped busbars of varying lengths:
[0004] Most fixtures currently use a fixed structure, which can only match conductors of a specific length. When processing workpieces of different specifications, it is necessary to frequently change fixtures or manually adjust the positioning, which is time-consuming, labor-intensive, and prone to human error.
[0005] To accommodate multiple size adjustments, some fixtures often adopt a loosely spliced design, which can easily cause vibration due to cutting forces during machining, leading to tool chatter and workpiece deformation. In addition, the positions of through holes and T-slots need to be determined manually, which is time-consuming and labor-intensive.
[0006] Therefore, there is an urgent need to design a drilling and milling device for conductive busbars to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this invention is to provide a drilling and milling device for conductive busbars, which has the advantage of flexibly adapting to U-shaped conductive busbars of different lengths within a single tooling, and solves the problems mentioned in the background art.

By rotating the first bolt, the second sliding seat slides relative to the first sliding seat.
[0013] Furthermore, the first sliding seat includes a third connecting plate and two fourth connecting plates. The two ends of the third connecting plate are connected to the fourth connecting plates. The two fourth connecting plates are attached to the outer surfaces of the two side portions. The third connecting plate is attached to the top surface of the conductive busbar.
[0014] Furthermore, the first sliding seat can slide relative to the support seat to change the height of the accommodating cavity, so that the accommodating cavity can accommodate conductive busbars of different thicknesses.

By rotating the second bolt, the first sliding seat slides relative to the support base.
[0017] Furthermore, a limiting block is fixedly connected to the support base. The limiting block is located inside the accommodating cavity and limits the movement of the conductive busbar. A third connecting groove adapted to the first connecting groove is provided on the limiting block.
[0018] Furthermore, the limiting block includes a first surface and two second surfaces. The two ends of the first surface are connected to the second surfaces. The first surface is fitted with the inner surface of the bottom, and the second surface is fitted with the inner surface of the side.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0029] The following is a reference to the appendix. Figure 1 To be continued Figure 6 This invention describes a drilling and milling device for conductive busbars.
[0030] The conductive bus 4 includes a bottom 41 and two side portions 42. The two ends of the bottom 41 are connected to the two side portions 42 respectively to form a groove-shaped structure, and the cross-sectional shape of the conductive bus 4 is similar to the letter "U".
[0031] Most fixtures currently use a fixed structure and can only match conductor bars of a specific length. When processing workpieces of different specifications, it is necessary to frequently change fixtures or manually adjust the positioning, which is time-consuming, labor-intensive, and prone to human error.
[0032] To accommodate multiple size adjustments, some fixtures often adopt a loosely spliced design, which can easily cause vibration due to cutting forces during machining, leading to tool chatter and workpiece deformation. In addition, the positions of the through hole 33 and the T-slot need to be determined manually, which is time-consuming and labor-intensive.
[0033] Therefore, this drilling and milling processing device includes a support base 1, on which a limiting block 12 is fixedly connected. The limiting block 12 limits the conductive busbar 4. The support base 1 is provided with a first sliding seat 2. A receiving cavity 18 for placing the conductive busbar 4 is provided between the first sliding seat 2 and the support base 1. The first sliding seat 2 has a first connecting groove 26. The first sliding seat 2 has a second sliding seat 3. The second sliding seat 3 has a second connecting groove 34 and a through hole 33. The first connecting groove 26 and the second connecting groove 34 form a T-shaped groove. The conductive busbar 4 is drilled and milled through the through hole 33 and the T-shaped groove. The second sliding seat 3 abuts against the bottom ends of the two side parts 42. The second sliding seat 3 can slide relative to the first sliding seat 2 to determine the position of the corresponding second connecting groove 34 and through hole 33 according to the side parts 42 of different lengths.
[0034] The receiving cavity 18 consists of a first sliding seat 2, a second sliding seat 3, and a support seat 1. The opening of the receiving cavity 18 is located at the opposite end of the second sliding seat 3. The conductive bus 4 is placed through the opening of the receiving cavity 18. After the conductive bus 4 is placed into the receiving cavity 18, the conductive bus 4 is limited by the limiting block 12. The second sliding seat 3 slides until it abuts against the bottom ends of the two side parts 42. By sliding the second sliding seat 3, conductive bus 4 of different lengths can be accommodated, thereby determining the positions of the second connecting groove 34 and the through hole 33 on conductive bus 4 of different lengths. Based on the different lengths of conductive bus 4, T-slots of different lengths can be determined, so that the positions of the T-slots and the through holes 33 are determined by the linkage of the sliding seats, avoiding manual measurement and marking, and reducing the risk of human error.
[0035] The second connecting groove 34 is the head of the T-slot, and the first connecting groove 26 is the tail of the T-slot. The T-slot is formed by the second connecting groove 34 and the first connecting groove 26, which provides a stable guide path for the tool and avoids milling groove offset or hole position deviation.
[0036] Furthermore, the second sliding seat 3 includes a first connecting plate 31 and a second connecting plate 32, the first connecting plate 31 and the second connecting plate 32 are fixedly connected, the second connecting groove 34 and the through hole 33 are formed on the first connecting plate 31, and the second connecting plate 32 abuts against the bottom surface of the two side portions 42.
[0037] Regarding the sliding method of the second sliding seat 3, preferably, the first sliding seat 2 has a slot 23, the first connecting plate 31 is slidably connected in the slot 23, the slot 23 has a first sliding groove 24, and the second connecting plate 32 is slidably connected to the first sliding groove 24. By setting the slot 23, the first connecting plate 31 and the first sliding seat 2 are located on the same plane. By setting the sliding groove, the sliding direction of the second sliding seat 3 is restricted.
[0038] The first sliding seat 2 has a first screw hole 25, which communicates with the slot 23. A first bolt 27 is screwed into the first screw hole 25. The first bolt 27 is rotatably connected to the second sliding seat 3. By rotating the first bolt 27, the second sliding seat 3 slides relative to the first sliding seat 2. Regarding the rotatable connection between the first bolt 27 and the second sliding seat 3, the second sliding seat 3 has a rotating slot. The end of the first bolt 27 is fixedly connected to a rotating block with a diameter larger than the first bolt 27. The first bolt 27 is rotatably connected to the rotating slot on the second sliding seat 3 through the rotating block, so as to achieve the effect that the second sliding seat 3 will not rotate but only slide when the first bolt 27 rotates.
[0039] Furthermore, the first sliding seat 2 includes a third connecting plate 21 and two fourth connecting plates 22. The two ends of the third connecting plate 21 are connected to the fourth connecting plates 22. The two fourth connecting plates 22 are attached to the outer surfaces of the two side portions 42. The third connecting plate 21 is attached to the top surface of the conductive busbar 4.
[0040] The first sliding seat 2 can slide relative to the support seat 1 to change the height of the accommodating cavity 18, so that the accommodating cavity 18 can hold conductive busbars 4 of different thicknesses, and the first sliding seat 2 can slide to limit and fix the conductive busbars 4.
[0041] Regarding the sliding method of the first sliding seat 2, preferably, the support seat 1 is provided with a second sliding groove 11, and the fourth connecting plate 22 is slidably connected in the second sliding groove 11.
[0042] A through groove 14 is provided on the support base 1, and the first bolt 27 is located in the through groove 14 to avoid interference between the first bolt 27 and the support base 1 when the first sliding seat 2 slides.
[0043] Furthermore, a support plate 15 is fixedly connected to the support base 1. A second screw hole 17 is provided on the support plate 15, and a second bolt 16 is screwed into the second screw hole 17. The second bolt 16 is rotatably connected to the third connecting plate 21. By rotating the second bolt 16, the first sliding seat 2 slides relative to the support base 1. Regarding the rotatable connection between the second bolt 16 and the first sliding seat 2, a rotating groove is provided on the first sliding seat 2. A rotating block with a diameter larger than the second bolt 16 is fixedly connected to the end of the second bolt 16. The second bolt 16 is rotatably connected to the rotating groove on the first sliding seat 2 through the rotating block, so as to achieve the effect that the first sliding seat 2 will not rotate but only slide when the second bolt 16 rotates.
[0044] The limiting block 12 is located inside the accommodating cavity 18. The limiting block 12 is provided with a third connecting groove 13 that is adapted to the first connecting groove 26. Specifically, the limiting block 12 includes a first surface 122 and two second surfaces 121. The two ends of the first surface 122 are connected to the second surfaces 121. When the conductive busbar 4 is limited by the limiting block 12, the first surface 122 is in contact with the inner side surface of the bottom 41, and the second surface 121 is in contact with the inner side surface of the side portion 42.
[0045] After the conductive busbar 4 is fixed in place, the machine is milled and drilled along the T-slot and through hole 33 using a milling machine and a drilling machine.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
