Description

Technical Field

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

[0002] Copper busbars are used in many electrical devices and appliances. To improve the integration and reliability of the electrical control system, nuts need to be riveted to the surface of the copper busbar. After riveting the nuts, the connection structure of the copper busbar is more compact and the reliability is better. The riveting process of the copper busbar requires the nuts to be embedded into the pre-set holes on the surface of the copper busbar and riveted by a riveting machine. The corresponding nut embedding and positioning process generally requires manual operation, which is not only extremely inefficient, but also poses safety hazards.

[0003] Chinese utility model patent CN218963919U discloses a copper busbar processing and riveting fixture, comprising: a feed pipe, a stamping head, a stamping base, a first clamping member, and a second clamping member. The feed pipe has an inlet and an outlet at both ends, which are interconnected. The first and second clamping members are rotatably mounted on opposite sides of the outlet of the feed pipe. The first and second clamping members selectively abut or separate. When the first and second clamping members abut each other, a receiving cavity is formed between the first and second clamping members and the feed pipe, which is interconnected with the outlet. The stamping head and the stamping base are respectively located on opposite sides of the outlet of the feed pipe. The stamping head selectively drives the first and second clamping members to separate and abut against the stamping base after passing through the receiving cavity. This utility model's copper busbar processing and riveting fixture has a simple and reasonable structural design, can replace manual nut preparation, and is beneficial to improving processing efficiency and safety.

[0004] However, this tooling still has defects when riveting nuts onto copper busbars: during the riveting process, the copper busbars will be deformed due to the pressure, which will cause the riveting position of the nuts to change and the riveting to be inaccurate. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, this utility model provides a copper busbar riveting fixture.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution:

[0007] A copper busbar riveting fixture is suitable for riveting copper busbars with both ends bent and with rivet nuts pressed at the bent portions;

[0008] The tooling includes a riveting table mounted on a tooling base. The riveting table includes an integrally formed base and a top. The top is provided with a positioning part that can constrain one side of the bent portion on the copper busbar, and a guide part for positioning the rivet nut.

[0009] The bent part and nut to be riveted are constrained to the top of the platform. The riveting head is pressed down from the top of the platform to rivet the nut into the nut hole of the bent part.

[0010] The pedestal is equipped with an elastic support assembly that can support the bent portion on the other side of the copper busbar.

[0011] By adopting the above technical solution, during the downward force application of the riveting head, the bent part of the copper busbar and the riveting nut cannot be displaced due to the constraint of the positioning part, thus ensuring the accuracy of the riveting position; at the same time, when the copper busbar is subjected to downward pressure, it tends to move downward, but due to the supporting effect of the elastic support component, the two bends on the copper busbar, which are set at different positions, always remain in their original bent state and will not deform, thus ensuring the consistency of the copper busbar.

[0012] A further provision of the above technical solution is that the positioning part is a positioning groove provided on the upper surface of the platform and extending to one side of the platform, and the bent part of the copper busbar can slide into the positioning groove from the side.

[0018] A further configuration of the above technical solution is as follows: the platform top is formed on the platform base and is connected to the platform base by a column; the column base has an inclined limiting surface on the side facing the copper busbar; the top support plate has a relief groove that cooperates with the column base, and the relief groove is located below the limiting surface.

[0019] A further feature of the above technical solution is that the limiting surface is inclined from bottom to top toward the copper busbar.

[0020] A further provision of the above technical solution is that: the lower end of the riveting head is provided with a riveting groove, the riveting groove is capable of accommodating the passage of the copper busbar with a bent portion, and pressing the copper busbar tightly against the side of the platform top;

[0021] The riveting surface is located at the top of the riveting groove.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: during the downward force application of the riveting head, due to the constraint of the positioning part, the bent part of the copper busbar and the riveting nut cannot be displaced, thereby ensuring the accuracy of the riveting position; at the same time, when the copper busbar is subjected to downward pressure, it tends to move downward, but due to the supporting action of the elastic supporting component, the two bends on the copper busbar, which are arranged at different positions, always remain in their original bent state and will not deform, thus ensuring the consistency of the copper busbar.

[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] like Figure 1-6 As shown in the figure, this embodiment discloses a copper busbar riveting fixture.

[0037] A copper busbar riveting fixture is suitable for a copper busbar 400 with both ends bent and the riveting of the nut 1 is performed at the bent portion 410.

[0038] It includes a riveting table 200 mounted on a tooling base 100. The riveting table 200 includes an integrally formed base 210 and a top 220. The top 220 is provided with a positioning part that can constrain the one-sided bent portion 410 on the copper busbar 400, and a guide part for positioning the riveting nut 1.

[0039] The bent part 410 to be riveted and the nut are constrained to the top of the platform 220. The riveting head 500 presses downward from above the top of the platform 220 to rivet the nut into the nut hole 411 of the bent part 410.

[0040] The pedestal 210 is provided with an elastic support component 300 that can support the bent portion 410 on the other side of the copper busbar 400.

[0041] The above is the basic scheme of this embodiment.

[0042] Specific reference Figure 1 As shown, the riveting table 200 and the elastic support assembly 300 are stacked on the tooling base 100 in sequence. The top 220 of the riveting table 200 is located above the elastic support assembly 300. The elastic support assembly 300 can float vertically within a small range relative to the base 210 of the riveting table 200 to adapt to the position change of the copper busbar 400 during the riveting process.

[0043] The copper busbar 400 has two symmetrical bends 410 on the side that needs to be riveted, and each bend 410 has a nut hole 411. The diameter of the nut hole 411 is usually smaller than the outer diameter of the riveting part of the rivet nut 1. In this way, when the rivet nut 1 is pressed into the nut hole 411, the riveting part and the hole wall of the nut hole 411 can be interference-fitted, thereby achieving the fastening effect of the rivet nut 1 and the copper busbar 400.

[0044] When riveting the copper busbar 400, the two opposing bent portions 410 on the copper busbar 400 are arranged vertically. The bent portion 410 on the side to be riveted is positioned in the positioning part on the platform top 220 for constraint and limitation. At the same time, the rivet nut 1 is positioned in the guide part for constraint. In this arrangement, the positions of the guide part and the positioning part are such that the nut hole 411 and the rivet nut 1 correspond. After positioning, the rivet head is pressed downward to press the rivet nut 1 into the nut hole 411.

[0045] Based on the above settings, during the downward force application of the riveting head, due to the constraint of the positioning part, the bent part 410 of the copper busbar 400 and the riveting nut 1 cannot be displaced, thereby ensuring the accuracy of the riveting position.

[0046] At the same time, when the copper busbar 400 is subjected to downward pressure, it tends to move downward. However, due to the supporting effect of the elastic support component 300, the two bends on the copper busbar 400, which are arranged vertically, always remain in their original bending state and will not deform, thus ensuring the consistency of the copper busbar 400.

[0047] Specifically, the positioning part is a positioning groove 221 provided on the upper surface of the platform 220 and extending to one side of the platform 220, and the bent part 410 of the copper busbar 400 can slide into the positioning groove 221 from the side.

[0048] Specific reference Figure 3 As shown, the positioning groove 221 is a positioning recess 312 provided on the upper end surface of the platform 220. The positioning recess 312 extends to the side to form an opening, so that the side of the copper busbar 400 that connects with the bent part 410 can be in close contact with the side of the platform 220, thereby ensuring that the bending angle of the bent part 410 remains vertical.

[0049] To ensure consistency between the rivet nut and the nut hole 411, in this embodiment, the guide part is a guide groove 223 recessed in the positioning groove 221. The guide groove 223 can accommodate the head of the rivet nut 1 and expose the rivet part above.

[0050] During positioning, the head of the rivet nut is inserted into the guide groove 223, and the rivet part of the rivet nut extends above the guide groove 223, so that it can contact the bent part 410.

[0051] In this embodiment, the center of the press-fit nut 1 is a through connecting hole. In order to prevent the side wall of the press-fit nut 1 from deforming towards the connecting hole during the riveting process, in this embodiment, a guide post 320 is provided in the guide groove 223. The guide post 320 can extend into the connecting hole and abut against the inner wall of the connecting hole to ensure the consistency of the inner wall of the connecting hole.

[0052] Preferably, the guide groove 223 is recessed within the positioning groove 221, and the riveting part protrudes above the bottom of the guide groove 223.

[0053] The rivet nut is positioned and installed in the guide groove 223. At the same time, the bent portion 410 of the copper busbar 400 is embedded in the positioning groove 221. At this time, since the outer diameter of the rivet part of the rivet nut 1 is larger than the nut hole 411 on the bend, the bent portion 410 is held above the rivet nut. In order to ensure the constraint of the positioning groove 221 on the bent portion 410, in this embodiment, the depth of the positioning groove 221 is greater than the length of the rivet part of the rivet nut, so that the bent portion 410 can be constrained at least at the bottom into the positioning groove 221, so as to achieve the positioning effect of the positioning groove 221 on the bent portion 410.

[0054] The ends of the copper busbar 400 are usually set as corners. In order to avoid collisions between the positioning grooves 221 and the corners during riveting, in this embodiment, the two corners of the positioning grooves 221 located inside the platform top 220 are set as arc-shaped connecting sidewalls.

[0055] Preferably, in this embodiment, the connecting sidewall of one corner is configured as an arc-shaped wall connecting with both sides, and the other corner is configured as an outwardly protruding circular groove 222, with a notch provided on the side of the circular groove 222 facing the corner to form a connection with the corner, as detailed in the following reference. Figure 3 As shown.

[0056] Based on the above configuration, the corner of the bent portion 410 can be placed into the circular groove 222, thereby avoiding interference between the side wall of the positioning groove 221 and the bent portion 410, which would cause the bent portion 410 to deform.

[0057] In this embodiment, the specific implementation of the elastic support component 300 is as follows:

[0058] The elastic support assembly 300 includes a support plate 310 and an elastic member 330 disposed below the support plate 310. The lower end of the elastic member 330 supports the riveting table 200, and the upper end supports the support plate 310.

[0059] When the riveting head 500 presses the bent portion 410 downward, it will press the entire copper busbar 400 downward, causing the copper busbar 400 to sink. In this embodiment, in the initial state, the top plate 310 is held upward by the elastic member 330, and at the same time, the copper busbar 400 is held upward. In this way, when the copper busbar 400 sinks, the top plate 310 is pressed downward, which ensures that the positions of the two bent portions 410 on the copper busbar 400 are always kept in the initial state, ensuring the consistency of the copper busbar 400 structure.

[0060] Specifically, the base 210 is provided with a limiting hole 211; a guide post 320 is also provided in the limiting hole 211, the guide post 320 is used to guide the supporting direction of the elastic member 330; the lower end surface of the supporting plate 310 is provided with a guide hole 311 that can accommodate the upper end of the guide post 320, and the upper end of the guide post 320 can move axially relative to the guide hole 311.

[0061] Specific reference Figure 4 As shown, the lower end of the guide post 320 is fixed to the limiting hole 211 on the base 210, and the upper end of the guide post 320 extends into the guide hole 311 on the lower end face of the top holding plate 310. When the top holding plate 310 floats up and down due to the elastic holding action of the elastic member 330, the upper end of the guide post 320 can slide in the guide hole 311.

[0062] Preferably, in this embodiment, the elastic element 330 is a spring, which is sleeved on the guide post 320.

[0063] Preferably, the top plate 310 is provided with a recess 312 that mates with the bent portion 410 on the other side of the copper busbar 400.

[0064] In order to limit the floating position of the top plate 310, in this embodiment, the top plate 220 is formed on the base 210 and is connected to the base 210 by a column 230; the column 230 is provided with an inclined limiting surface 231 on the side facing the copper busbar 400; the top plate 310 is provided with a relief groove that cooperates with the column 230, and the relief groove is located below the limiting surface 231.

[0065] Preferably, the limiting surface 231 is inclined from bottom to top toward the copper busbar 400.

[0066] Specific reference Figure 5 As shown, when the top plate 310 floats upward under the action of the elastic member 330, the limiting surface 231 stops the side of the top plate 310, preventing the top plate 310 from moving upward, thereby limiting the highest position of the top plate 310.

[0067] In addition, in order to fully match the lateral structure of the copper busbar 400 and to completely press the side of the copper busbar 400 near the bend 410 onto the platform top 220, in this embodiment, the lower end of the riveting head 500 is provided with a riveting groove 501. The riveting groove 501 can accommodate the copper busbar 400 with the bend and press the copper busbar 400 onto the side of the platform top 220.

[0068] The riveting surface 501.1 is located at the top of the riveting groove 501.

[0069] Specific reference Figure 6 As shown, the riveting groove 501 is formed on the lower end face of the riveting head 500, so that two staggered press feet 510 are formed on both sides of the riveting groove 501; and an opening is provided on the side to accommodate the copper busbar 400 extending laterally. The lower end of the riveting groove 501 is open and communicates with the opening.

[0070] During riveting, the side of the copper busbar 400 with the bent portion 410 is inserted into the riveting groove 501, and the riveting surface 501.1 at the top of the riveting groove 501 presses the bent portion 410 downward; at the same time, the two press feet 510 clamp the two side walls of the copper busbar 400 after they are misaligned and abutted, so as to ensure the consistency of the copper busbar 400 in the vertical position.

[0071] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
