Description

Technical Field

[0001] This utility model relates to the field of copper busbar riveting technology, specifically a multi-station riveting device for copper busbar nuts. Background Technology

[0002] Copper busbar riveting is a widely used connection process in fields such as power electronics, new energy, and rail transportation. It is mainly used to fix nuts, studs, or conductive connectors to copper busbars to ensure reliable mechanical strength and electrical conductivity. For example, in public document 202323230467.9, a multi-station copper busbar riveting device is described. The copper busbar workpiece to be riveted is placed on a receiving platform, allowing each extrusion post to be inserted into a riveting hole on the workpiece. Nuts to be riveted are inserted into each receiving hole, causing the magnet at the receiving hole to magnetically attract the nuts. A hydraulic press drives the pressing platform closer to the receiving platform, causing each nut to be riveted to move closer to a corresponding extrusion post, so that each nut abuts against the copper busbar workpiece. A cylinder drives a sliding plate to slide within a sliding groove, ensuring that the non-magnetic portion of the sliding plate is positioned at the top of each receiving hole to prevent damage to the magnets during the riveting process. The hydraulic press continues to drive the pressing table closer to the receiving table, and in conjunction with the sliding carrier plate, rivets the nuts to be riveted into the riveting holes on the copper busbar workpiece. Under the elastic force of the compression springs, the extrusion columns apply force to the nuts to eject the riveted copper busbar workpiece, facilitating unloading.

[0003] In order to ensure the quality of the riveting process, traditional copper busbar riveting devices require workers to accurately install the copper busbars to be processed on the equipment. After installation, the devices cannot be self-positioned and adjusted well, which makes the installation difficult. If any deviation occurs, it will seriously affect the riveting quality, making the operation difficult and causing inconvenience to the workers. Utility Model Content

[0018] 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.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] In order to ensure the quality of the riveting process, the traditional copper busbar riveting device requires the operator to accurately install the copper busbar to be processed on the equipment. After installation, it cannot be positioned and adjusted well by itself, which makes the installation difficult. If there is any deviation, it will seriously affect the riveting quality, thus making the operation difficult and causing inconvenience to the operator.

[0021] In view of this, the present invention provides a multi-station riveting device for copper busbar nuts. Through the cooperation of the base plate, the adjustment device, and the second horizontal plate, the device can automatically perform positioning and adjustment after the copper busbar is installed, so as to ensure the working quality during riveting. It also greatly reduces the installation difficulty of the copper busbar and the work difficulty of the workers, thus making it more convenient for the workers to use.

[0022] Example 1: By Figure 1 , 2 As shown in section 3, a multi-station riveting device for copper busbar nuts includes a base plate 1. A vertical plate 8 is fixedly connected to the top of the base plate 1. A first horizontal plate 5 is provided on the front of the vertical plate 8. A second horizontal plate 4 is provided below the first horizontal plate 5. Multiple riveting blocks 41 are fixedly connected to the bottom of the second horizontal plate 4. An adjusting device 2 is provided above the base plate 1. The adjusting device 2 includes: a support plate 21, fixedly connected to the top of the base plate 1; a sliding plate 22, slidably engaged with the outer wall of the support plate 21; a connecting block 23, fixedly connected to the bottom of the sliding plate 22; a threaded rod 24, threadedly connected to the inner wall of the connecting block 23; and two support plates 25, respectively... The servo motor 26 is fixedly connected to the top two sides of the base plate 1 and rotatably connected to the outer wall of the threaded rod 24 via bearings; the servo motor 26 is fixedly connected to the outer wall of the support plate 25, and its output end is fixedly connected to one end of the threaded rod 24; two infrared receivers 27 are provided and fixedly connected to the top two sides of the slide plate 22 respectively; two infrared transmitters 28 are provided and fixedly connected to the two sides of the second horizontal plate 4 respectively; wherein, the servo motor 26 drives the threaded rod 24 to drive the slide plate 22 to move along the outer wall of the support plate 21 through the connecting block 23, and the infrared receivers 27 and infrared transmitters 28 detect the corresponding positions of the slide plate 22 and the second horizontal plate 4;

[0023] In the specific implementation process, it is worth noting that the models of hydraulic cylinder 10, servo motor 26, infrared receiver 27, and infrared transmitter 28 are not limited, as long as they meet the usage requirements. Furthermore, this application should be equipped with a control processor to process and analyze the operating status of infrared receiver 27 and infrared transmitter 28, and to control hydraulic cylinder 10 and servo motor 26 to perform processing operations. The connection method, cooperation principle, and operation steps between the control processor and hydraulic cylinder 10, servo motor 26, infrared receiver 27, and infrared transmitter 28 are all existing well-known technologies. Therefore, this application does not impose any restrictions on them. Those skilled in the art should interpret them broadly. Servo motor 26 can change the position of slide plate 22 through threaded rod 24 so that positioning can be achieved through the cooperation of infrared receiver 27 and infrared transmitter 28.

[0024] Furthermore, the top of the slide plate 22 is machined with a placement groove 221, and the inner wall of the rivet block 41 is fixedly connected with a magnet 42.

[0025] In the specific implementation process, it is worth noting that the workers put the copper to be processed into the inside of the placement groove 221, and the setting of the magnet 42 can stably restrict the nut to the bottom groove of the rivet block 41.

[0026] Furthermore, a top plate 9 is fixedly connected to the upper part of the outer wall of the vertical plate 8, and a hydraulic cylinder 10 is fixedly connected to the bottom of the top plate 9. The output end of the hydraulic cylinder 10 is fixedly connected to the top of the first horizontal plate 5.

[0027] In the specific implementation process, it is worth noting that the hydraulic cylinder 10 can drive the first horizontal plate 5 to move, and then use the second horizontal plate 4 to drive the riveting block 41 to move downward, thereby realizing the riveting work of the nut.

[0028] Specifically, when using this multi-station riveting device for copper busbar nuts, the operator first places the copper busbar into the placement groove 221, then installs the nut in the bottom groove of the riveting block 41, and then uses the magnet 42 to limit the nut. Then, the infrared receiver 27 and infrared transmitter 28 can be turned on for positioning. When the infrared receiver 27 receives the signal emitted by the infrared transmitter 28, it means that the processing position is appropriate. When the infrared receiver 27 does not receive the signal emitted by the infrared transmitter 28, the servo motor 26 drives the threaded rod 24 to rotate. The threaded rod 24 can then drive the slide plate 22 to move along the outer wall of the support plate 21 through the connecting block 23, thereby adjusting the position of the copper busbar. When the infrared receiver 27 receives the signal from the infrared transmitter 28, the servo motor 26 is turned off, and then the hydraulic cylinder 10 is turned on. At this time, the hydraulic cylinder 10 can drive the second horizontal plate 4 to move downward through the first horizontal plate 5, thereby achieving the riveting of the nut through the riveting block 41.

[0029] Example 2: From Figure 1 , 2 As can be seen from points 3 and 4, the interior of the slide plate 22 is equipped with a demolding device 3. The demolding device 3 includes: multiple push plates 32, which are respectively attached to the four corners of the inner wall of the slide plate 22; multiple first springs 31, which are respectively fixedly connected to the bottom of the multiple push plates 32 and are all fixedly connected to the inner wall of the slide plate 22; wherein, when the first spring 31 is compressed, it will give the push plates 32 a reverse force so as to push the copper busbar being processed by the push plates 32.

[0030] In the specific implementation process, it is worth noting that when the first spring 31 deforms, it will exert an upward force on the push plate 32, which can lift the copper busbar away from the inside of the placement groove 221, so that the workers can take out the copper busbar more conveniently. It should be noted that the workers should replace the first spring 31 regularly to avoid the phenomenon that the elastic potential energy of the first spring 31 decreases and the work quality is reduced. There is no limit to the specific replacement cycle, as long as it meets the use requirements.

[0031] Furthermore, vertical rods 6 are fixedly connected to the top four corners of the second horizontal plate 4, and the outer walls of the multiple vertical rods 6 are respectively inserted into the inner walls of the four corners of the first horizontal plate 5. The outer walls of the multiple vertical rods 6 are each sleeved with a second spring 7, and the top and bottom of the multiple second springs 7 are respectively fixedly connected to the multiple vertical rods 6 and the second horizontal plate 4.

[0032] In the specific implementation process, it is worth noting that when riveting, the elastic potential energy of the second spring 7 can be used to automatically buffer and protect against impact at the moment of contact, thereby avoiding damage or deformation of the nut or copper busbar, which would affect the quality of riveting. It should be noted that the second spring 7 should be replaced regularly to avoid the phenomenon of reduced work quality due to the decrease in the elastic potential energy of the second spring 7. There is no limit to the specific replacement cycle, as long as it meets the usage requirements.

[0033] Specifically, based on the above embodiment one, when riveting is performed, the second horizontal plate 4 drives the vertical rod 6 to move along the inner wall of the first horizontal plate 5, while changing the shape of the second spring 7. At the same time, the push plate 32 moves along the inner wall of the slide plate 22 and compresses the first spring 31. The elastic potential energy of the first spring 31 and the second spring 7 can then provide buffer protection. After riveting is completed, the first spring 31 can drive the push plate 32 to move upward, thereby achieving demolding and making it easier for workers to remove the copper busbar.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
