Description

Technical Field

[0001] This utility model relates to the field of copper busbar technology, and in particular to a copper busbar shaping fixture. Background Technology

[0002] like Figure 1 As shown, a copper busbar connector 7 in the prior art includes three copper sheets 71 and a plastic part 72 injection molded onto the copper sheets 71 and connecting multiple copper sheets 71 into a whole. Extensions 721 are provided at both ends and sides of the plastic part 72, and an outer toothed sleeve 7211 is integrally formed on the extensions 721. Each copper sheet 71 has an electrical terminal 711 extending from both sides of the plastic part 72. The electrical terminals 711 on corresponding sides of the three copper sheets 71 are coplanar. To ensure the assembly accuracy of the three copper sheets 71 of the copper busbar connector 7, it is necessary to ensure that the electrical terminals 711 on corresponding sides of the three copper sheets 71 remain on the same horizontal plane during the injection molding process. Additionally, a conductive ring 7111 is fixed to the bottom of one side of the electrical terminal 711 of the three copper sheets 71. During injection molding, it is necessary to ensure that the conductive ring 7111 does not shift. Therefore, there is an urgent need to develop a fixture that can shape and position the copper sheets 71 during the injection molding process of the aforementioned copper busbar connector 7. Utility Model Content

[0003] The purpose of this utility model is to provide a copper busbar shaping fixture, which can shape and position the electrical terminals of copper sheets and improve the injection molding and assembly accuracy of copper busbar connectors.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a copper busbar shaping fixture, including a base, an extension rod fixed on the base, a mounting seat fixed at the end of the extension rod, a lifting drive device on the mounting seat, a lifting plate connected to the lifting output end of the lifting drive device, and a plurality of upper pressing blocks and upper positioning blocks provided at the bottom of the lifting plate corresponding to the power receiving end of the copper sheet. The plurality of upper pressing blocks are arranged in a straight line on the outer side of the bottom of the lifting plate, and the plurality of upper positioning blocks are arranged in a straight line on the inner side of the bottom of the lifting plate. The end faces of the plurality of upper pressing blocks and the end faces of the plurality of upper positioning blocks are coplanar.

[0005] A support plate is fixed on the base. The support plate is provided with a plurality of lower pressing blocks and lower positioning blocks. The upper pressing blocks and the lower pressing blocks are vertically aligned and correspond one-to-one with each other, and the end faces of the plurality of lower pressing blocks are coplanar and the end faces of the plurality of lower positioning blocks are coplanar. When the lifting plate presses against the support plate, a pressing gap is formed between the upper pressing blocks and the lower pressing blocks to form a pressing connection end, and a positioning gap is formed between the upper positioning blocks and the lower positioning blocks to form a positioning connection end. The spacing of the pressing gap is smaller than the spacing of the positioning gap.

[0006] By adopting the above technical solution, the lifting drive device drives the lifting plate to move down to a predetermined position, so that the copper sheet is clamped in the pressing gap between the upper and lower pressure blocks. At the same time, the positioning gap between the upper and lower positioning blocks can circumferentially limit the electrical end of the copper sheet. Under the pressure of the upper and lower pressure blocks, the end of the copper sheet near the plastic part may be twisted and deformed. At this time, since the spacing of the positioning gap is greater than the spacing of the pressing gap, the end of the copper sheet near the plastic part can produce slight deformation within the tolerance range of the positioning gap and the pressing gap. This not only leaves space for the copper sheet to produce extrusion deformation, but also controls the deformation of the copper sheet within a controllable range. Then, the plastic part is injection molded on the outside of the copper sheet to form a copper busbar connector. This ensures that the electrical ends of multiple copper sheets in the injection-molded copper busbar connector can always be kept on the same horizontal plane, improving assembly accuracy. It has the effect of shaping and positioning the electrical ends of the copper sheet and improving the injection molding and assembly accuracy of the copper busbar connector.

[0007] A further feature of this invention is that the lower pressure block has a first positioning notch corresponding to the conductive ring, and the lower positioning block has a second positioning notch corresponding to the conductive ring, the first positioning notch and the second notch cooperate to form a positioning space for the positioning conductive ring.

[0008] By adopting the above technical solution, when the copper sheet is placed on the lower pressure block and the lower positioning block, the conductive ring of the copper sheet can be positioned in the positioning space enclosed by the first positioning notch and the second positioning notch.

[0009] A further feature of this invention is that an avoidance space is formed between adjacent upper pressure blocks and upper positioning blocks, and between lower pressure blocks and lower positioning blocks.

[0010] By adopting the above technical solutions, the clearance space can improve the ease of assembly between the upper pressure block and the upper positioning block, and between the lower pressure block and the lower positioning block.

[0011] A further feature of this invention is that the lifting plate has a first mounting groove and a second mounting groove corresponding to the upper pressing block and the upper positioning block, and a plurality of the upper pressing blocks and the upper positioning blocks are inserted and fixed in the corresponding first mounting groove and the second mounting groove.

[0012] By adopting the above technical solution, the upper pressure block and the upper positioning block can be detachably installed at the bottom of the lifting plate, which facilitates the disassembly and assembly of the upper pressure block and the upper positioning block, and also improves the positioning stability of the upper pressure block and the upper positioning block at the bottom of the lifting plate.

[0013] A further feature of this invention is that the support plate has a third mounting groove and a fourth mounting groove corresponding to the lower pressing block and the lower positioning block, and a plurality of the lower pressing blocks and the lower positioning blocks are inserted and fixed in the corresponding third mounting groove and the fourth mounting groove.

[0014] By adopting the above technical solution, the lower pressure block and the lower positioning block can be detachably installed on the support plate, which facilitates the easy assembly and disassembly of the lower pressure block and the lower positioning block, and at the same time improves the positioning firmness of the lower pressure block and the lower positioning block on the top of the support plate.

[0015] A further feature of this invention is that the upper positioning block and the lower positioning block have clearance openings on the side near the plastic part.

[0016] By adopting the above technical solution, the setting of the clearance opening helps to improve the assembly compactness of this utility model.

[0017] A further feature of this invention is that a positioning post is fixedly provided on the support plate, and the upper end of the positioning post is provided with a guide portion for a positioning outer toothed sleeve.

[0018] By adopting the above technical solution, the insertion part can be inserted and positioned into the inner cavity of the outer tooth sleeve, thereby improving the injection molding accuracy between the plastic part and the outer tooth sleeve.

[0019] A further feature of this invention is that: the upper end of the threading part extends into a conical part, the bottom of the lifting plate is provided with an abutting post corresponding to the positioning post, the abutting post is provided with a conical hole corresponding to the conical part, and the conical part and the conical hole are positioned and engaged.

[0020] By adopting the above technical solution, the outer gear sleeve can be guided by the conical part and slid into the guide part, thereby improving the installation efficiency of the outer gear sleeve.

[0021] A further feature of this invention is that: a plurality of optical axes are vertically arranged on the support plate, and a plurality of guide holes are opened on the lifting plate corresponding to the optical axes, and the optical axes are guided and slidably engaged with the corresponding guide holes.

[0022] By adopting the above technical solutions, the consistency of the vertical lifting direction of the lifting platform can be improved.

[0023] A further feature of this invention is that the upper positioning block has a first receiving groove, in which a first elastic element and a first pressing block are provided. The first elastic element always has a tendency to drive the first pressing block out of the first receiving groove and abut against the upper end surface of the copper sheet. The lower positioning block has a second receiving groove, in which a second elastic element and a second pressing block are provided. The second elastic element always has a tendency to drive the second pressing block out of the second receiving groove and abut against the lower end surface of the copper sheet.

[0024] By adopting the above technical solution, the dual elastic force of the first elastic element and the second elastic element is used to make the first pressing block and the second pressing block elastically abut against the upper and lower ends of the copper sheet, which can buffer the deformation generated at the end of the copper sheet near the plastic part, and help reduce the torsional deformation of the copper sheet.

[0025] In summary, this utility model has the following beneficial effects:

[0026] A mounting base is installed on an extended rod of the base, and a lifting drive device is installed on the mounting base. The output end of the lifting drive device is connected to a lifting plate. At the bottom of the lifting plate, corresponding to the electrical connection end of the copper sheet, there are several upper pressing blocks and upper positioning blocks, with a support plate fixed thereon. The support plate has several lower pressing blocks and lower positioning blocks. The upper pressing blocks and lower pressing blocks, and the upper positioning blocks and lower positioning blocks, correspond one-to-one and are vertically aligned. When the lifting plate presses against the support plate, a pressing gap is formed between the upper and lower pressing blocks corresponding to the electrical connection ends, and a positioning gap is formed between the upper and lower positioning blocks corresponding to the electrical connection ends. The spacing of the pressing gaps is smaller than the spacing of the positioning gaps. During injection molding, the lifting drive device drives the lifting plate to move down to a predetermined position, clamping the copper sheet within the pressing gap between the upper and lower pressing blocks, while simultaneously clamping the upper and lower positioning blocks... The positioning gap between the positioning blocks can circumferentially limit the electrical connection end of the copper sheet. Under the pressure of the upper and lower pressure blocks, the end of the copper sheet near the plastic part may be twisted and deformed. At this time, since the spacing of the positioning gap is greater than the spacing of the pressing gap, the end of the copper sheet near the plastic part can produce slight deformation within the tolerance range of the positioning gap and the pressing gap. This not only leaves space for the copper sheet to undergo extrusion deformation, but also controls the deformation of the copper sheet within a controllable range. Then, the plastic part is injection molded onto the copper sheet to form a copper busbar connector. This ensures that the electrical connection ends of multiple copper sheets in the injection-molded copper busbar connector can always be kept on the same horizontal plane, improving assembly accuracy. It has the effect of shaping and positioning the electrical connection end of the copper sheet and improving the injection molding and assembly accuracy of the copper busbar connector.

[0036] The present invention will be further described below with reference to the accompanying drawings. Specific Implementation Example 1

[0038] A copper busbar shaping fixture, such as Figures 2-5As shown, the system includes a base 1, an extension rod 11 fixed on the base 1, a mounting base 12 fixed at the end of the extension rod 11, a lifting drive device 13 on the mounting base 12, a lifting plate 3 connected to the lifting output end of the lifting drive device 13, and several upper pressing blocks 31 and upper positioning blocks 32 on the bottom of the lifting plate 3 corresponding to the power connection end 711 of the copper sheet 71. The several upper pressing blocks 31 are arranged in a straight line on the outer side of the bottom of the lifting plate 3, and the several upper positioning blocks 32 are arranged in a straight line on the inner side of the bottom of the lifting plate 3. The end faces of the several upper pressing blocks 31 and the several upper positioning blocks 32 are coplanar. A support plate 2 is fixed on the base 1, and several lower pressing blocks 21 and lower positioning blocks 22 are provided on the support plate 2. The upper pressing blocks 31 and lower pressing blocks 21 are connected in a straight line. The upper positioning block 32 and the lower positioning block 22 are vertically aligned and correspond one-to-one. The end faces of the lower pressing blocks 21 and the end faces of the lower positioning blocks 22 are coplanar. When the lifting plate 3 presses against the support plate 2, a pressing gap 4 is formed between the upper pressing block 31 and the lower pressing block 21, and a positioning gap 5 is formed between the upper positioning block 32 and the lower positioning block 22, and the spacing of the pressing gap 4 is smaller than the spacing of the positioning gap 5. The support plate 2 is vertically provided with a number of optical axes 24, and the lifting plate 3 is provided with a number of guide holes 34 corresponding to the optical axes 24. The optical axes 24 and the corresponding guide holes 34 guide and slide together, which can improve the consistency of the vertical lifting direction of the lifting plate 3.

[0039] like Figures 4-7As shown, the lower pressure block 21 has a first positioning notch 211 corresponding to the conductive ring 7111, and the lower positioning block 22 has a second positioning notch 221 corresponding to the conductive ring 7111. The first positioning notch 211 and the second notch cooperate to form the positioning space of the positioning conductive ring 7111. When the copper sheet 71 is placed on the lower pressure block 21 and the lower positioning block 22, the conductive ring 7111 of the copper sheet 71 can be positioned with the positioning space enclosed by the first positioning notch 211 and the second positioning notch 221. An avoidance space 6 is formed between adjacent upper pressure blocks 31 and upper positioning blocks 32, and between lower pressure blocks 21 and lower positioning blocks 22. The avoidance space 6 can improve the assembly convenience between upper pressure blocks 31 and upper positioning blocks 32, and between lower pressure blocks 21 and lower positioning blocks 22. The lifting plate 3 has a first mounting groove 310 and a second mounting groove 320 corresponding to the upper pressure blocks 31 and upper positioning blocks 32. Several upper pressure blocks 31 and upper positioning blocks 32 are inserted and fixed to the corresponding first mounting grooves. The upper pressing block 31 and the upper positioning block 32 are detachably installed on the bottom of the lifting plate 3 within the groove 310 and the second mounting groove 320. This facilitates the assembly and disassembly of the upper pressing block 31 and the upper positioning block 32, while also improving the positioning stability of the upper pressing block 31 and the upper positioning block 32 at the bottom of the lifting plate 3. The support plate 2 has a third mounting groove 210 and a fourth mounting groove 220 corresponding to the lower pressing block 21 and the lower positioning block 22. Several lower pressing blocks 21 and lower positioning blocks 22 are inserted and fixed in the corresponding third mounting groove 210 and fourth mounting groove 220, allowing the lower pressing blocks 21 and the lower positioning blocks 22 to be detachably installed on the support plate 2. This facilitates the assembly and disassembly of the lower pressing blocks 21 and the lower positioning blocks 22, while also improving the positioning stability of the lower pressing blocks 21 and the lower positioning blocks 22 at the top of the support plate 2. The upper positioning block 32 and the lower positioning block 22 have a clearance opening 321 on the side near the plastic part 72. The setting of the clearance opening 321 helps to improve the assembly compactness of this utility model.

[0040] like Figures 2-7 As shown, a positioning post 23 is fixed on the support plate 2. The upper end of the positioning post 23 is provided with a guide portion 231 for positioning the outer toothed sleeve 7211. The guide portion 231 can be inserted into the inner cavity of the outer toothed sleeve 7211 for positioning, thereby improving the injection molding accuracy between the plastic part 72 and the outer toothed sleeve 7211. A conical portion 232 extends from the upper end of the guide portion 231. The bottom of the lifting plate 3 is provided with an abutment post 33 corresponding to the positioning post 23. The abutment post 33 is provided with a conical hole 330 corresponding to the conical portion 232. The conical portion 232 and the conical hole 330 are positioned and fitted. The outer toothed sleeve 7211 can be guided by the conical portion 232 and slide into the guide portion 231, thereby improving the installation efficiency of the outer toothed sleeve 7211.

[0041] The basic working principle of this utility model is as follows: A mounting base 12 is provided on the extension rod 11 of the base 1, and a lifting drive device 13 is provided on the mounting base 12. The output end of the lifting drive device 13 is connected to the lifting plate 3. A number of upper pressing blocks 31 and upper positioning blocks 32 are provided at the bottom of the lifting plate 3 corresponding to the power receiving end 711 of the copper sheet 71 to fix the support plate 2. A number of lower pressing blocks 21 and lower positioning blocks 22 are provided on the support plate 2. The upper pressing blocks 31 and lower pressing blocks 21, and the upper positioning blocks 32 and lower positioning blocks 22 are connected. The components are vertically aligned and correspond one-to-one. When the lifting plate 3 presses against the support plate 2, a pressing gap 4 is formed between the upper pressing block 31 and the lower pressing block 21, corresponding to the pressing connection terminal 711. A positioning gap 5 is formed between the upper positioning block 32 and the lower positioning block 22, corresponding to the positioning connection terminal 711. The spacing of the pressing gap 4 is smaller than the spacing of the positioning gap 5. During injection molding, the lifting drive device 13 drives the lifting plate 3 to move down to the predetermined position, so that the copper sheet 71 is clamped between the upper pressing block 31 and the lower pressing block 21. Within the gap 4, the positioning gap 5 between the upper positioning block 32 and the lower positioning block 22 can circumferentially limit the electrical terminal 711 of the copper sheet 71. Under the pressure of the upper pressure block 31 and the lower pressure block 21, the end of the copper sheet 71 near the plastic part 72 may be twisted and deformed. At this time, since the spacing of the positioning gap 5 is greater than the spacing of the pressing gap 4, the end of the copper sheet 71 near the plastic part 72 can produce slight deformation within the tolerance range of the positioning gap 5 and the pressing gap 4. This not only leaves space for the copper sheet 71 to produce extrusion deformation, but also controls the deformation of the copper sheet 71 within a controllable range. Then, the plastic part 72 is injection molded onto the copper sheet 71 to form the copper busbar connector 7. This ensures that the electrical terminals 711 of the multiple copper sheets 71 of the injection-molded copper busbar connector 7 can always be kept on the same horizontal plane, improving the assembly accuracy. This has the effect of shaping and positioning the electrical terminal of the copper sheet and improving the injection molding and assembly accuracy of the copper busbar connector. Specific Implementation Example 2

[0043] A copper busbar shaping fixture, such as Figure 8As shown, the difference between this embodiment and specific embodiment one is that: the upper positioning block 32 has a first receiving groove 322, and the first receiving groove 322 is provided with a first elastic member 3221 and a first pressing block 3222. The first elastic member 3221 always has the tendency to drive the first pressing block 3222 out of the first receiving groove 322 and abut against the upper end surface of the copper sheet 71. The lower positioning block 22 has a second receiving groove 212, and the second receiving groove 212 is provided with a second elastic member 2121 and a second pressing block 3222. Block 2122 and the second elastic element 2121 always have the tendency to drive the second pressing block 2122 to extend out of the second receiving groove 212 and abut against the lower end face of the copper sheet 71. By utilizing the double elastic force of the first elastic element 3221 and the second elastic element 2121, the first pressing block 3222 and the second pressing block 2122 elastically abut against the upper and lower ends of the copper sheet 71, which can buffer the deformation generated at the end of the copper sheet 71 near the plastic part 72, which is beneficial to reduce the torsional deformation of the copper sheet 71.

[0044] The other structures of this embodiment are the same as those of Specific Embodiment 1, and will not be described again here.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
