Description

Technical Field

[0001] This utility model belongs to the field of new energy parts processing, and specifically relates to a busbar connection riveting device and a busbar connection. Background Technology

[0002] In the production of busbar connectors for new energy vehicle batteries, metal plates and nuts need to be fixedly connected in the connector. Connection methods include welding and riveting. In the riveting method, the pressing block for riveting is usually fixedly connected to the upper worktable, and the carrier is fixed to the lower worktable. After riveting a set of busbar connectors, the riveted busbar connector needs to be removed from the carrier, and then a new set of metal plates and nuts are placed in sequence. After placement, the upper worktable is started for riveting. This method is not only inefficient for riveting a single type of busbar connector, but also requires removing the pressing block on the upper worktable and the carrier on the lower worktable to replace the matching carrier when riveting different models of busbar connectors. The carrier needs to be positioned and installed again, resulting in even lower riveting efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a more efficient busbar connection riveting device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a busbar connection riveting device, which includes an upper worktable, a lower worktable, a plurality of positioning blocks installed on the lower worktable, and a plurality of riveting carriers fixedly installed on the lower worktable by the positioning blocks. Each riveting carrier includes a carrier body, a handle formed on the carrier body, a guide post, and a pressure block. The upper end surface of the carrier body is provided with a plurality of positioning holes, and a positioning surface is formed on one or both sides of the positioning holes. The pressure block is provided with a guide hole that matches the guide post.

[0005] In another embodiment, the lower end face of the pressure block is provided with a pressing surface that is recessed inward; when the pressing surface contacts the upper end face of the nut, the distance between the upper end face of the pressure block and the upper end face of the carrier body is the same as the downward distance of the metal sheet.

[0006] In another embodiment, the handle is vertically connected to the side of the carrier body; this facilitates manual or conveying mechanism to hold the riveting carrier and deliver it between the upper and lower worktables.

[0007] In another embodiment, a positioning sleeve is provided in the positioning hole, and the upper end face of the positioning sleeve is lower than the upper end face of the carrier body; the height difference between the upper end face of the positioning sleeve and the upper end face of the carrier body can further limit the displacement of the nut when it is pressed together, and further ensure the accuracy and strength of the riveting.

[0008] In another embodiment, a limiting post is fixedly inserted inside the positioning sleeve; the limiting post can prevent the nut from being deformed due to excessive compression during the riveting process of the upper worktable moving downward.

[0009] In another embodiment, the riveting carrier is provided with multiple carrier bodies; by providing multiple carrier bodies, the riveting efficiency can be improved.

[0010] In another embodiment, the positioning block has multiple oblong holes, and the positioning block is detachably connected to the lower worktable through bolt assemblies located in the lower worktable and the oblong holes.

[0011] This utility model also provides a busbar connecting strip formed by riveting the busbar connecting strip using the above-mentioned busbar connecting strip riveting device. The busbar connecting strip includes a metal sheet and a nut. The metal sheet is provided with a riveting hole that matches the upper end of the nut. The upper end of the nut includes a first boss, a toothed ring formed above the first boss for embedding the metal sheet during riveting, and a guide platform formed above the toothed ring.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: the nut of the busbar connecting bar passes through the positioning hole, the upper end of the nut protrudes above the positioning hole, and the metal plate of the busbar connecting bar has a riveting hole that matches the upper end of the nut. The metal plate is sleeved on the upper end of the nut through the riveting hole, and the metal plate has at least one side that is in contact with the positioning surface. When the upper worktable moves downward, the lower end surface of the upper worktable contacts the upper end surface of the positioning block. Then, with the cooperation of the guide post and the guide hole, the positioning block is pressed by the upper worktable along the direction perpendicular to the upper end surface of the carrier body towards the carrier body. The positioning block then contacts the metal plate and pushes it downward, finally pressing the upper end of the nut into the riveting hole and connecting the nut and the metal plate as one, thus improving the riveting efficiency. Because the busbar connecting bar is equipped with a toothed ring, the nut and the metal plate are more firmly riveted during riveting. Attached Figure Description
