[0033] from Figure 1 As can be seen, the riveting assembly of this utility model includes a riveting device (not shown in the figure), and a first fixture 1 and a second fixture 4 arranged opposite to each other. The first fixture 1 and the second fixture 4 are respectively installed on opposite sides of the riveting device. The workpiece to be riveted is placed in the second fixture 4. Specifically, in conjunction with... Figure 2 As shown, the workpieces to be riveted include a first workpiece 7 and a second workpiece 71. The second workpiece 71 is placed on the second fixture 4, and the first workpiece 7 is placed in the riveting area of ​​the second workpiece 71. During riveting, the riveting device can press the first fixture 1 against the second fixture 4, thereby completing the riveting connection between the first workpiece 7 and the second workpiece 71.

[0034] It should be noted that the riveting assembly of this utility model can be used for riveting components of a 4D millimeter radar. Specifically, the first workpiece to be riveted 7 can be the radar's PIN connector, and the second workpiece to be riveted 71 can be the radar's main housing. In use, the main housing is placed on the second fixture 4, and the connector is placed in the riveting area of ​​the housing.

[0035] In order to install the first fixture 1 and the second fixture 4 onto the riveting equipment respectively, the first fixture 1 includes a first support 11 and a first locking device 2 disposed on the first support 11. The first locking device 2 is used to fix the first fixture 1 onto the riveting equipment. As shown in the example, the two first locking devices 2 are respectively disposed opposite to each other on both sides near the first support 11, so as to fix the first locking devices 2 onto the riveting equipment from both sides.

[0036] In other embodiments, the number of first locking devices 2 is not limited, and there can be multiple devices. The installation position of the first locking devices 2 on the first support 11 is not limited, as long as the first fixture 1 can be fixed to the riveting device.

[0037] Furthermore, the second fixture 4 includes a second support 41 and a second locking device 42 disposed on the second support 41. The second locking device 42 is used to fix the second fixture 4 to the riveting equipment and is disposed opposite to the first fixture 1. As shown in the example, the two second locking devices 42 are respectively disposed opposite to each other on both sides near the second support 41 to fix the second locking devices 42 to the riveting equipment from both sides.

[0038] In other embodiments, the number of second locking devices 42 is not limited, and there can be multiple devices. The installation position of the second locking devices 42 on the second support 41 is not limited, as long as the second fixture 4 can be fixed to the riveting device.

[0039] according to Figure 1 In the embodiment, the shape and structure of the second locking device 42 are the same as those of the first locking device 2, and the installation and disassembly methods are also the same as those of the first locking device 2. The following description uses the first locking device 2 as an example.

[0040] Combination Figure 3 As shown, the first locking device 2 includes a lock head 21, an abutment portion 22, a lock pin 23, a lock shaft 24, and a locking portion 25 connected in sequence. The lock head 21 is a flat ellipse shape for easy gripping and turning. The abutment portion 22 is a truncated cone shape, and the diameter of the abutment portion 22 is larger than that of the lock pin 23, used to abut against one side of the first support seat 11. The lock pin 23 and the lock shaft 24 are both cylindrical, and the locking portion 25 is cylindrical, protruding on both radial sides of the end of the shaft portion of the lock shaft 24.

[0041] During locked installation, combined Figure 4As shown, the abutting part 22 abuts against one side of the first bearing seat 11, the locking pin 23 passes through the through hole 15 of the first bearing seat 11, and the locking shaft 24 passes through the locking hole of the riveting device (not shown in the figure). By turning the lock head 21 and adjusting the position of the locking part 25, the locking part 25 abuts against the other side of the riveting device. Thus, through the abutting force between the abutting part 22 and the locking part 25, the first bearing seat 11 and the riveting device are locked together, thereby fixing the first bearing seat 11 of the first fixture 1 to the riveting device.

[0042] It can be seen that the shape and structure of the first locking device 2 facilitates the installation of the first fixture 1. The first fixture 1 can be firmly installed on the riveting equipment simply by turning the lock head 21. Similarly, the first fixture 1 can also be quickly and easily removed by turning the lock head 21, thus realizing the quick installation and removal of the first fixture 1.

[0043] To facilitate the transport of the second fixture 4, optionally, such as Figure 1 and Figure 2 As shown, handles 14 can also be provided on both sides of the second fixture 4, and the second fixture 4 can be easily moved by pulling the handles 14.

[0044] To improve the accuracy of riveting, the edge of the second bearing seat 41 of the second fixture 4, such as Figure 1 , Figure 2 and Figure 5 As shown, a display device 43 may also be provided. The display device 43 is used to display the model of the workpiece to be riveted placed on the second support 41, so as to determine whether the first fixture 1 and the second fixture 4 are compatible with the workpiece to be riveted. At the same time, it is convenient to set riveting parameters such as riveting pressure value and riveting angle by the model of the workpiece to be riveted, so as to improve the accuracy of riveting and the yield.

[0045] Combination Figure 5 It can be clearly seen that the display device 43 can be three lights. By encoding the on and off states of the lights in different locations, the model number of the workpiece to be riveted, placed in the second fixture 4, can be determined. In other embodiments, the display device 43 can also be, but is not limited to, a display screen, to directly display the model number of the workpiece to be riveted.

[0046] To ensure the workpiece to be riveted is positioned correctly and to further improve the accuracy of riveting, the second fixture 4 of the riveting assembly of this utility model, combined with... Figure 1 and Figure 5 As shown, it may also include a positioning platform 5 protruding from the middle of the second bearing seat 41, a second mounting platform 6 protruding from the middle of the positioning platform 5, and a support platform 62 protruding from the middle of the second mounting platform 6. The positioning platform 5, the second mounting platform 6, and the support platform 62 together form a multi-layer boss, and the second workpiece 71 to be riveted is placed on the multi-layer boss (e.g., Figure 2As shown), the multi-layered bosses can completely support all parts of the second workpiece 71 to be riveted, thereby limiting the placement position of the second workpiece 71 to be riveted.

[0047] like Figure 2 As shown, the riveting surface of the second workpiece 71 to be riveted is located on the support platform 62, and the first workpiece 7 to be riveted is placed on the riveting surface of the second workpiece 71 to be riveted. During riveting, the support platform 62 can provide support for the second workpiece 71 to be riveted and the first workpiece 7 to be riveted, preventing the riveting force from damaging the second workpiece 71 to be riveted and the first workpiece 7 to be riveted, thereby ensuring the position of the riveting point.

[0048] Combination Figure 2 As shown, the second workpiece to be riveted 71 is placed on the positioning table 5, and the second workpiece to be riveted 71 is adapted to the second mounting table 6, and the riveting area of ​​the second workpiece to be riveted 71 is placed on the support table 62, and the first workpiece to be riveted 7 is placed on the support table 62.

[0049] Furthermore, combined Figure 5 As shown, the support platform 62 may also be provided with a slot 63, which is used for the connection part of the PIN connector to place the PIN, so as to prevent it from hindering the riveting process.

[0050] To determine the location of the riveting points on the workpiece to be riveted, such as... Figure 4 As shown, a lateral adjustment hole 51 may be provided at the positioning table 5. The lateral adjustment hole 51 is located near the four corners of the positioning table 5. The lateral adjustment hole 51 is a horizontal slotted hole. The second workpiece to be riveted 71 is provided with a positioning bolt (not shown in the figure) at the corresponding position. The positioning bolt can move laterally within the lateral adjustment hole 51, so that the second workpiece to be riveted 71 can be moved laterally to the riveting position and then tightened to fix it.

[0051] Furthermore, as shown in the figure, the second mounting platform 6 may also be provided with longitudinal adjustment holes 61. Multiple longitudinal adjustment holes 61 are provided at the edge of the second mounting platform 6 and near the support platform 62. The second workpiece to be riveted 71 is also provided with positioning bolts (not shown in the figure) at the corresponding positions. The positioning bolts can move longitudinally within the longitudinal adjustment holes 61, so that the second workpiece to be riveted 71 is moved longitudinally to the riveting position and then tightened and fixed, thereby limiting the position of the second workpiece to be riveted 71 in both the lateral and longitudinal directions.

[0052] Moreover, such as Figure 5 As shown, a clearance opening 64 can also be provided at the edge of the second mounting platform 6 to avoid the second workpiece 71 to be riveted, and to prevent the second workpiece 71 to be riveted from interfering with the second mounting platform 6 during installation.

[0053] Furthermore, a detection device 44 can also be provided on the second support 41. The detection device 44 is located at both ends of the second support 41 as shown in the figure, and extends to both sides of the second mounting platform 6. The detection devices 44 on both sides are set at the same height. That is, when the first workpiece 7 to be riveted and the second workpiece 71 to be riveted are placed on the second fixture 4, the detection devices 44 on both sides can detect whether the placement of the first workpiece 7 to be riveted and the second workpiece 71 to be riveted is stable, and can detect the distance between the placement of the second workpiece 71 to be riveted and the detection device 44 to determine whether it is placed in place, so as to further ensure that the first workpiece 7 to be riveted and the second workpiece 71 to be riveted are placed in place, thereby ensuring accurate riveting position.

[0054] The first fixture 1 and the second fixture 4 of the riveting assembly of this utility model are arranged opposite to each other, from... Figure 1 and Figure 6 It can be clearly seen that the first mounting platform 12 protrudes from the middle of the first bearing seat 11 of the first fixture 1 toward the second fixture 4. The first mounting platform 12 is provided with a fixing post 13 and a pressing riveting part 3.

[0055] Combination Figure 2 It can be seen that the fixing post 13 and the riveting part 3 are set on the support platform 62 of the second fixture 4. The fixing post 13 presses the first workpiece 7 to be riveted 7 against the second workpiece 71 to be riveted 7 in the normal direction. That is, the fixing post 13 fixes the normal position of the first workpiece 7 to be riveted 7 and the second workpiece 71 to be riveted 7, thereby cooperating with the second fixture 4 to fix the first workpiece 7 to be riveted 7 and the second workpiece 71 to be riveted 7 in the longitudinal, transverse and normal directions, thereby further ensuring the accuracy of the riveting position.

[0056] Optionally, a spring (not shown in the figure) may be provided at the connection between the fixed column 13 and the first bearing seat 11. When the riveting surfaces of the first workpiece to be riveted 7 and the second workpiece to be riveted 71 are not stable and have a height tolerance, the fixed column 13 can be self-adjusted by the spring to ensure the pressing allowance of the fixed column 13 and prevent the first workpiece to be riveted 7 and the second workpiece to be riveted 71 from being damaged by pressure.

[0057] exist Figure 6 In one embodiment, the first mounting platform 12 of the first fixture 1 has four riveting parts 3 evenly distributed, and the fixing post 13 is located in the middle of the four riveting parts 3. In other embodiments, the number of riveting parts 3 is not limited and can be multiple, to ensure that the first workpiece to be riveted 7 and the second workpiece to be riveted 71 are effectively connected.

[0058] Combination Figure 7 As shown, the press-fit component 3 includes a support column 31, a press-fit column 32, and a press-fit end 33 connected in sequence. The support column 31 is mounted on the first mounting platform 12, and the press-fit column 32 and the press-fit end 33 extend toward the second fixture 4 (as shown). Figure 1(As shown). During riveting, the riveting end 33 presses against the first workpiece 7 to be riveted and the second workpiece 71 to be riveted, so as to complete the riveting.

[0059] As can be seen from the figure, the diameter of the support column 31 is larger than that of the pressing column 32, and the diameter of the pressing column 32 is larger than that of the pressing end 33. With this design, the larger diameter of the support column 31 allows the pressing part 3 to be installed more stably on the first mounting platform 12, and the larger diameter of the pressing column 32 makes the pressing end 33 more stable.

[0060] Furthermore, such as Figure 8 As shown, four riveting components 3 are provided between the support column 31 and the first mounting platform 12, and an adjusting spring 34 applies force simultaneously. The elasticity of the adjusting spring 34 can finely adjust the length of the riveting component 3 extending towards the second fixture 4. When the riveting surfaces of the first workpiece 7 to be riveted and the second workpiece 71 to be riveted are not stable, the riveting component 3 can self-adjust, that is, it can adjust according to the riveting surface condition, thereby effectively adjusting so that the riveting force at each riveting point of the first workpiece 7 to be riveted and the second workpiece 71 to be riveted is the same, thereby ensuring the riveting quality.

[0061] Optionally, the press-fit part 3 can be made of tungsten steel, which is wear-resistant and rust-proof, and can increase the service life of the press-fit part 3.

[0062] The riveting assembly of this utility model uses a combination of two sets of opposing first fixtures 1 and second fixtures 4 to achieve the riveting assembly of the first workpiece 7 to be riveted and the second workpiece 71 to be riveted. The riveting assembly of this utility model displays the model numbers of the first workpiece 7 and the second workpiece 71 to be riveted via a display device 43, and determines whether the first workpiece 7 and the second workpiece 71 to be riveted are properly positioned via a detection device 44, effectively controlling damage and scrapping of the workpieces to be riveted due to improper placement or incorrect use of fixtures.

[0063] Moreover, four rivet parts 3 can be used to simultaneously fix four rivet points. Each of the four rivet parts 3 is equipped with an adjusting spring 34. When the tolerance height of the riveted workpieces is inconsistent, the four rivet parts 3 can be adjusted to be subjected to force simultaneously to ensure the quality of riveting.

[0064] Furthermore, the first fixture 1 of the riveting assembly of this utility model is provided with a first locking device 2, and the second fixture 4 is provided with a second locking device 42. The first locking device 2 and the second locking device 42 can respectively facilitate the quick installation of the first fixture 1 and the second fixture 4 onto the riveting equipment, thereby realizing the quick replacement of the riveting equipment.

[0065] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
