[0002] Self-clinching nut column, also known as self-clinching stud, is a kind of fastener used in sheet metal, thin plate, chassis, cabinet. The self-clinching nut column has a hexagonal shape at one end and a cylindrical shape at the other end. There is a back-cut groove between the two ends, which is in the shape of an internal thread. The hexagonal end of the self-clinching nut column can be pressed into the preset hole of the thin plate by a press machine.

[0003] The manufacturing process of the radiator usually involves the nut column riveting process. The traditional nut column riveting process is manually operated by workers. The worker first places the radiator on the fixture of the riveting machine, and then places the nut column in the hole of the radiator. After placement, press the start button, the riveting machine starts, and the nut column is riveted. Afterwards, the worker removes the riveted radiator.

[0032] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments, and only the parts related to the embodiments of the present utility model are shown.

[0033] Embodiment 1:

[0034] As Figure 1 shown, the present utility model provides an automatic nut column riveting device, which includes a machine table 1, an indexing plate 2, a feeding mechanism 3, a riveting mechanism 4, a discharging mechanism 5 and at least one nut column feeding mechanism 6. The indexing plate 2 is movably connected to the middle of the upper end of the machine table 1. The feeding mechanism 3, at least one nut column feeding mechanism 6, the riveting mechanism 4 and the discharging mechanism 5 are sequentially arranged on the circumferential side of the indexing plate 2, and the feeding mechanism 3, each nut column feeding mechanism 6, the riveting mechanism 4 and the discharging mechanism 5 are all fixed on the machine table 1. Specifically, the indexing plate 2 is movably connected to the middle of the upper end of the machine table 1, and the indexing plate 2 is connected to the rotation driving mechanism in the machine table 1. Driven by the rotation driving mechanism, the indexing plate 2 can rotate by a pre-set angle, so as to sequentially rotate the multiple carrying fixtures 21 (described below) on the indexing plate 2 according to the process. The feeding mechanism 3, at least one nut column feeding mechanism 6, the riveting mechanism 4 and the discharging mechanism 5 are all fixed on the machine table 1, and the feeding mechanism 3, at least one nut column feeding mechanism 6, the riveting mechanism 4 and the discharging mechanism 5 are sequentially arranged on the circumferential side of the indexing plate 2 and are evenly distributed at equal angles on the circumferential side of the indexing plate 2. The automatic nut column riveting device of the present application can not only perform nut column riveting on the radiator 7, but also perform automatic nut column riveting on other structures that require nut column riveting, and only need to set the corresponding carrying fixture 21.

[0035] Working principle of the automatic riveting equipment for nut studs: Workers place the radiator 7 on the feeding mechanism 3, and the feeding mechanism 3 can automatically feed the radiator 7 onto its corresponding carrying jig 21. The indexing plate 2 rotates, and the radiator 7 rotates with the indexing plate 2, passing through each nut stud feeding mechanism 6 in sequence. Each nut stud feeding mechanism 6 automatically pre-installs the nut studs onto the corresponding nut stud installation positions of the radiator 7 in sequence. Each nut stud feeding mechanism 6 pre-installs one nut stud at a time. After the pre-installation of the nut studs is completed, the radiator 7 is rotated to the detection mechanism 8 (described below). The detection mechanism 8 detects whether the pre-installed nut studs are in place. If not, an alarm is given. If the detection is qualified, the radiator 7 continues to rotate to the riveting mechanism 4. The riveting mechanism 4 operates to press the nut studs pre-installed on the radiator 7 into the radiator 7. Then, the radiator 7 rotates to the discharging mechanism 5, and the discharging mechanism 5 can automatically complete the discharging action of the radiator 7.

[0036] The utility model simultaneously conveys multiple radiators 7 through the indexing plate 2, and the feeding mechanism 3, at least one nut stud feeding mechanism 6, the riveting mechanism 4, and the discharging mechanism 5 on the circumferential side of the indexing plate 2 simultaneously perform processing, improving production efficiency. Moreover, the nut stud feeding mechanism 6 accurately pre-installs the nut studs, improving the product yield rate, thereby meeting the user's usage requirements.

[0037] As an optional implementation manner, such as Figure 1As shown in the figure, the feeding mechanism 3 includes a first grasping component 31 and a first conveying component 32. The first conveying component 32 is fixed to the machine table 1 through a bracket, and the first end of the first conveying component 32 is adjacent to the indexing plate 2. The first grasping component 31 is fixedly connected to the first conveying component 32, and the first grasping component 31 is arranged at the first end of the first conveying component 32. The first conveying component 32 is used to sequentially convey the radiators 7, and the first grasping component 31 is used to grasp the radiators 7 within the limiting area of the first conveying component 32 onto the indexing plate 2. Specifically, the first conveying component 32 is fixed to the machine table 1 through a bracket, and the bracket can support the first conveying component 32, so that the first conveying component 32 and the indexing plate 2 are on the same horizontal plane. The first end of the first conveying component 32 is adjacent to the indexing plate 2, which facilitates the first grasping component 31 to grasp and transfer the radiators 7 on the first end of the first conveying component 32 to the corresponding carrying fixture 21 on the indexing plate 2. The first conveying component 32 can sequentially convey multiple radiators 7. A limiter is provided at the first end of the first conveying component 32, which can limit and fix the radiators 7 in the front in the limiting area, facilitating the first grasping component 31 to grasp the radiators 7 within the limiting area. When the first grasping component 31 grasps and places a radiator 7 onto the corresponding carrying fixture 21 of the feeding mechanism 3, and the mechanisms corresponding to the other carrying fixtures 21 on the indexing plate 2 complete the corresponding operations, the indexing plate 2 rotates to rotate the carrying fixture 21 after discharging to the corresponding position of the feeding mechanism 3, and the feeding mechanism 3 performs the feeding operation of the next radiator 7. The first conveying component 32 is a conveyor belt type conveying component.

[0038] A sensor is provided on the first conveying component 32. The sensor is communicatively connected to the main control unit 9. The sensor is used to detect whether there is a shortage of materials on the first conveying component 32. When it detects a shortage of materials on the first conveying component 32, the main control unit 9 controls the alarm unit 10 to give an audible and visual alarm to remind the worker to feed the radiator 7 onto the first conveying component 32. In the manual feeding of this application, the radiator 7 is placed on the first conveying component 32 for conveyance, reducing the safety risk and avoiding the riveting and pressing mechanism 4 from injuring the worker's hand.

[0039] As an optional implementation manner, such as Figure 2As shown in the figure, the first grasping component 31 includes a lateral movement structure 311, a longitudinal movement structure 312, and a grasping member 313. The longitudinal movement structure 312 is movably connected to the lateral movement structure 311, and the grasping member 313 is movably connected to the longitudinal movement structure 312. The lateral movement structure 311 is used to drive the longitudinal movement structure 312 and the grasping member 313 to perform lateral movement. The longitudinal movement structure 312 is used to drive the grasping member 313 to perform longitudinal movement. The grasping member 313 is a vacuum suction attachment. Specifically, the lateral movement structure 311 includes a lateral drive structure, a lateral lead screw, and a first fixing member. Both the lateral drive structure and the lateral lead screw are fixed on the first fixing member, and the lateral lead screw is fixedly connected to the lateral drive structure. The lateral drive structure can drive the lateral lead screw to rotate, thereby driving the longitudinal movement structure 312 movably connected to the lateral lead screw to perform lateral movement. The longitudinal movement structure 312 includes a longitudinal drive structure, a longitudinal lead screw, and a second fixing member. Both the longitudinal drive structure and the longitudinal lead screw are fixed on the second fixing member, and the longitudinal drive structure is fixedly connected to the longitudinal lead screw. The second fixing member is movably connected to the lateral lead screw through a slider. The longitudinal drive structure can drive the longitudinal lead screw to rotate, thereby driving the grasping member 313 movably connected to the longitudinal lead screw to perform longitudinal movement. When the lateral movement structure 311 moves, it can reciprocate the grasping member 313 above the first end of the feeding mechanism 3 and above the corresponding carrier fixture 21 of the feeding mechanism 3. When the lateral movement structure 311 adjusts the grasping member 313 above the first end of the feeding mechanism 3, the longitudinal drive structure drives the grasping member 313 to move, grasps the radiator 7 within the limiting area of the feeding mechanism 3, and then adjusts the grasping member 313 above the corresponding carrier fixture 21 of the feeding mechanism 3 through the lateral movement structure 311. The longitudinal drive structure drives the grasping member 313 to move, and places the radiator 7 obtained by the grasping member 313 onto the corresponding carrier fixture 21 of the feeding mechanism 3, completing the feeding. The lateral drive structure and the longitudinal drive structure are drive motors or drive cylinders.

[0040] The grasping member 313 is a vacuum suction attachment, and a plurality of suction nozzles are provided on the grasping member 313. The radiator 7 is vacuum-sucked through the suction nozzles to achieve the grasping of the radiator 7. The plurality of suction nozzles can ensure the stability of grasping the radiator 7.

[0041] As an optional implementation manner, such as Figure 1As shown in the figure, each nut post feeding mechanism 6 includes a feeding assembly 61. The feeding assembly 61 is fixed on the machine table 1, and one end of the feeding assembly 61 is located above the indexing plate 2. The feeding assembly 61 is used to pre-assemble the nut posts onto the corresponding radiator 7. In each nut post feeding mechanism 6 that is not adjacent to the feeding structure, the nut post feeding mechanism 6 includes an auxiliary assembly 62. The auxiliary assembly 62 is fixed on the feeding assembly 61, and the auxiliary assembly 62 is used to press the nut posts pre-assembled on the radiator 7. Specifically, the number of nut post feeding mechanisms 6 corresponds to the number of nut posts that the radiator 7 needs to install. The radiator 7 of this application needs to pre-assemble four nut posts, and each nut post feeding mechanism 6 pre-assembles one nut post at a time. Therefore, this application is provided with four nut post feeding mechanisms 6. The four nut post feeding mechanisms 6 are sequentially arranged on the periphery of the indexing plate 2 and are located between the feeding mechanism 3 and the detection mechanism 8 (described below), ensuring that the four nut posts are pre-assembled onto the radiator 7 in sequence. Each nut post feeding mechanism 6 includes a feeding assembly 61. The feeding assembly 61 includes a vibrating plate type automatic feeding part, a picking part, and an adjusting assembly. The vibrating plate type automatic feeding part is used to sequentially convey and sort the nut posts. The position of the picking part is adjusted through the adjusting assembly. When the adjusting assembly adjusts the picking part to the sorted nut posts, the picking part grabs the nut posts, and then the picking part is adjusted to the corresponding carrying fixture 21 through the adjusting assembly. The picking part pre-assembles the grabbed nut posts onto the corresponding nut post installation positions of the radiator 7.

[0042] More specifically, when the first nut post feeding mechanism 6 pre-assembles the first nut post, no auxiliary mechanism is required. When the second nut post feeding mechanism 6 pre-assembles the second nut post, the auxiliary assembly 62 on the second nut post feeding mechanism 6 presses the first nut post pre-assembled on the radiator 7. When the third nut post feeding mechanism 6 pre-assembles the third nut post, the auxiliary assembly 62 on the third nut post feeding mechanism 6 presses the first nut post and the second nut post pre-assembled on the radiator 7. When the fourth nut post feeding mechanism 6 pre-assembles the fourth nut post, the auxiliary assembly 62 on the fourth nut post feeding mechanism 6 presses the first nut post, the second nut post, and the third nut post pre-assembled on the radiator 7. The auxiliary assembly 62 pressing the nut posts that have been pre-assembled on the radiator 7 can prevent the vibration generated during the riveting operation of the riveting mechanism 4 from affecting the accuracy of the nut posts pre-assembled on the radiator 7, thereby improving the riveting accuracy of the riveting mechanism 4 and the yield rate of the product.

[0043] As an alternative implementation, as Figure 4As shown in the figure, the riveting mechanism 4 includes a driving member 41, an upper die 42 and a mounting base 43. The driving member 41 is fixed on the mounting base 43, and the mounting base 43 is fixed on the machine table 1, and the mounting base 43 is located on the side of the indexing plate 2. One end of the driving member 41 passes through the mounting base 43 and is fixedly connected to the upper die 42. The driving member 41 can drive the upper die 42 to move towards the indexing plate 2. Specifically, the mounting base 43 is semi-“I”-shaped and is clamped on the side of the indexing plate 2. The driving member 41 is a cylinder, and the driving member 41 is fixed on the machine table 1 through the mounting base 43. One end of the driving member 41 passes through the upper end of the mounting base 43 and is fixedly connected to the upper die 42. The upper die 42 corresponds to the bearing fixture 21 of the corresponding riveting mechanism 4 on the indexing plate 2. The driving member 41 can drive the upper die 42 to move towards the bearing fixture 21 corresponding to the upper die 42 (that is, drive the upper die 42 to move downward). The upper die 42 and the corresponding bearing fixture 21 cooperate with each other. The upper die 42 punches the radiator 7 on the corresponding bearing fixture 21, and rivets the pre-installed nut posts on the radiator 7 to the radiator 7, completing the automatic nut post riveting operation.

[0044] As an optional implementation manner, as Figure 1 shown in the figure, the blanking mechanism 5 includes a second grasping component 51, a second conveying component 52 and a buffer blanking component 53. The second conveying component 52 is fixed on the machine table 1, and the first end of the second conveying component 52 is adjacent to the indexing plate 2. The second grasping component 51 is fixedly connected to the second conveying component 52, and the second grasping component 51 is arranged at the first end of the second conveying component 52. The second grasping component 51 is used to grasp the corresponding riveted radiator 7 on the indexing plate 2 onto the second conveying component 52, and the second conveying component 52 is used to sequentially convey the riveted radiators 7. The buffer blanking component 53 is fixed at the second end of the second conveying component 52, and the buffer blanking component 53 is used to buffer the radiators 7 conveyed by the second conveying component 52. Specifically, the second conveying component 52 is fixed on the machine table 1, and the second conveying component 52 and the indexing plate 2 are on the same horizontal plane, which is convenient for the second grasping component 51 to grasp the radiator 7 on the bearing fixture 21 corresponding to the blanking mechanism 5 onto the second conveying component 52. The second conveying component 52 is used to sequentially convey the multiple radiators 7 grasped by the second grasping component 51 onto the second conveying component 52 to complete blanking, which is convenient for the bearing fixture 21 corresponding to the blanking mechanism 5 to be reloaded, so that the bearing fixture 21 on the indexing plate 2 can work cyclically. The buffer blanking component 53 is fixed at the second end of the second conveying component 52, which can buffer the radiators 7 conveyed by the second conveying component 52 to prevent the radiators 7 from being scratched when falling into the collection box corresponding to the buffer blanking component 53, reducing the production cost. The second grasping component 51 is the same as the first grasping component 31 on the loading mechanism 3, and the second conveying component 52 is a conveyor belt type conveying component.

[0045] As an optional implementation manner, asFigure 3 As shown, it further includes a detection mechanism 8. The detection mechanism 8 is fixed on the machine table 1, and the detection mechanism 8 is arranged between the nut column feeding mechanism 6 for pre-installing the last nut column and the riveting mechanism 4. The detection mechanism 8 is used to detect whether the nut column on the corresponding radiator 7 on the indexing plate 2 is pre-installed in place. Specifically, the detection mechanism 8 is fixed on the machine table 1. One side of the detection mechanism 8 is adjacent to the nut column feeding mechanism 6 for pre-installing the last nut column, and the other side of the detection mechanism 8 is adjacent to the riveting mechanism 4. When the indexing plate 2 rotates, the radiator 7 pre-installed at the processing position of the nut column feeding mechanism 6 for pre-installing the last nut column can be rotated to the processing position of the detection mechanism 8. The detection mechanism 8 performs inductive detection on the pre-installed radiator 7 to detect whether the pre-installed nut column on the radiator 7 is in place. The detection mechanism 8 is communicatively connected to the main control unit 9. When it is detected that the nut column is not pre-installed in place, the system of the main control unit 9 pauses. After the worker checks and resumes, the detected radiator 7 is rotated to the processing position of the riveting mechanism 4 through the indexing plate 2 for riveting processing, so as to ensure that the installation accuracy of the nut column riveted by the riveting mechanism 4 is relatively high and the radiator 7 is not easily damaged. When the main control unit 9 receives the information that the nut column is not pre-installed in place sent by the detection mechanism 8, the main control unit 9 can control the alarm unit 10 to give an audible and visual alarm to prompt the worker.

[0046] As an optional implementation manner, the detection mechanism 8 includes a plurality of sensors, and the plurality of sensors are arranged in one-to-one correspondence with a plurality of nut column installation positions on the radiator 7. Specifically, the sensors are photoelectric proximity sensors. The plurality of sensors are arranged in one-to-one correspondence with a plurality of nut column installation positions on the radiator 7 to ensure that it can be detected whether the pre-installed nut column at each nut column installation position is in place, thereby improving the yield of the product. Four nut columns need to be pre-installed on the radiator 7 of the present application. Therefore, four sensors are provided on the detection mechanism 8, and the number of sensors can be adaptively set according to the number of nut column installation positions on the radiator 7.

[0047] As an optional implementation manner, as Figure 2 ​As shown in the figure, a plurality of carrier fixtures 21 for placing the radiator 7 are provided around the upper surface of the indexing plate 2, and the plurality of carrier fixtures 21 are respectively arranged in one-to-one correspondence with the feeding mechanism 3, each nut column feeding mechanism 6, the detection mechanism 8, the riveting mechanism 4, and the discharging mechanism 5. Specifically, the carrier fixture 21 is used to install and place the radiator 7, which facilitates the synchronous movement of the carrier fixture 21 driven by the rotation of the indexing plate 2, thereby driving the radiator 7 to perform riveting processing operations. The plurality of carrier fixtures 21 are arranged in an equiangular array around the upper surface of the indexing plate 2 to ensure that each time the indexing plate 2 rotates, the carrier fixture 21 can be rotated to the corresponding next working position according to the process. The number of the carrier fixtures 21 in this application is eight, and the eight carrier fixtures 21 respectively correspond to eight processing positions, including one processing position of the feeding mechanism 3, followed by four processing positions of the nut column feeding mechanisms 6, one processing position of the detection mechanism 8, one processing position of the riveting mechanism 4, and one processing position of the discharging mechanism 5. The number of the carrier fixtures 21 corresponds to the number of the processing mechanisms arranged on the circumferential side of the indexing plate 2.

[0048] As an optional implementation manner, as Figure 5 shown, it further includes a main control unit 9 and an alarm unit 10. The alarm unit 10, the feeding mechanism 3, each nut column feeding mechanism 6, the detection mechanism 8, the riveting mechanism 4, and the discharging mechanism 5 are all communicatively connected to the main control unit 9; the main control unit 9 is fixed on the machine table 1, and the alarm unit 10 is fixed on the main control unit 9. Specifically, the main control unit 9 is used to control the operation of the entire device. The main control unit 9 includes a human-machine interface, and the staff can use the human-machine interface to set various parameters such as the feeding speed of the device. The feeding mechanism 3 is communicatively connected to the main control unit 9, and the main control unit 9 can control the feeding mechanism 3 to start for feeding operations. Each nut column feeding mechanism 6 is communicatively connected to the main control unit 9, and the main control unit 9 can control each nut column feeding mechanism 6 to start for pre-assembling the nut columns. The detection mechanism 8 is communicatively connected to the main control unit 9, and the main control unit 9 can control the detection mechanism 8 to detect the pre-assembled radiator 7 to detect whether the nut columns are pre-assembled in place. The alarm unit 10 is communicatively connected to the main control unit 9. When the detection mechanism 8 detects that the pre-assembly is not in place or the first conveying component 32 is out of stock, the main control unit 9 controls the alarm unit 10 to give an audible and visual alarm.
