Description

Technical Field

[0001] The utility model relates to the technical field of riveting, in particular to riveting equipment. Background Art

[0002] Riveting equipment is a device that uses high-pressure processing to deform the plate and fix it with components such as rivet nuts and rivet screws.

[0003] In the prior art, the rivet head of the riveting equipment is located above the riveting hole of the sheet, and the rivet nut is located between the rivet head and the sheet or manually placed at the lower end of the rivet head. When the riveting equipment is started, the rivet head drives the rivet nut to be pressed into the riveting hole of the sheet. Specifically, the rivet nut has an annular oblique protrusion that can extend into the riveting hole of the sheet and the protruding length of the oblique protrusion is less than the thickness of the sheet. When the oblique protrusion of the rivet nut is in the riveting hole of the sheet, the top of the oblique protrusion is located in the middle of the riveting hole of the sheet. After the rivet head is pressed down, the sheet is deformed and pressed between the oblique protrusion and the main body of the rivet nut, so that the top of the oblique protrusion is flush with one side of the sheet, thereby restricting the sheet and preventing it from being separated from the rivet nut.

[0004] However, during the riveting process of this method, the thickness of the parts around the rivet holes of the plate will be reduced and extended to the side, and a concave part with a different thickness from other parts will easily appear around the rivet holes of the plate. That is to say, after the riveting operation is completed, the parts around the rivet holes of the plate are prone to sink, affecting the quality of the plate. Utility Model Content

Therefore, the above terms cannot be understood as limiting the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] refer to Figures 1 to 9A riveting device according to a preferred embodiment of the present invention will be described in detail below. The riveting device is used to press a self-clinching nut 800 into a self-clinching hole 9001 in a plate 900, wherein the plate 900 has at least one self-clinching hole 9001. The inner wall of the lower end of the self-clinching nut 800 extends outward to form an annular oblique protrusion 801, and an angled space 8001 is formed between the oblique protrusion 801 and the main portion of the self-clinching nut 800. The oblique protrusion 801 can extend into the self-clinching hole 9001.

[0033] The riveting equipment includes an equipment body 10 and a riveting device 20 , wherein the riveting device 20 is installed on the equipment body 10 .

[0034] The riveting device 20 includes a riveting body 21 , a riveting die 22 and a riveting component 23 , wherein the riveting die 22 and the riveting component 23 are both mounted on the riveting body 21 .

[0035] The riveting die 22 has a die hole 2201. When the plate 900 is placed on the riveting die 22, the rivet hole 9001 and the center of the die hole 2201 are on the same straight line. The inner wall of the die hole 2201 formed by the riveting die 22 protrudes toward the plate 900 to form a protrusion 221. The height of the part of the protrusion 221 close to the die hole 2201 is greater than the height of the part away from the die hole 2201. The protrusion 221 presses against the oblique convex portion 801 and the plate 900 to form the side wall of the rivet hole 9001.

[0036] The rivet pressing member 23 includes a rivet pressing driver 231 and a rivet pressing column 232, wherein the rivet pressing column 232 is connected to the rivet pressing driver 231 so as to be movable along its own axis. One end of the rivet pressing column 232 faces the rivet pressing die 22, and a rivet pressing head 2321 protrudes from the center of the end. The rivet pressing head 2321, the rivet hole 9001, and the center of the die hole 2201 are all located in the axial direction of the rivet pressing column 232. The rivet pressing head 2321 is adapted to fit into the screw hole of the rivet nut 800. It can be understood that when the rivet nut 800 is passed through the rivet head 2321, the center of the rivet head 2321, the center of the rivet nut 800, and the rivet hole 9001 are all in the axial direction of the rivet column 232. Therefore, when the rivet nut 800 moves along the axial direction of the rivet column 232 and presses against the plate 900, the screw hole of the rivet nut 800 and the center of the rivet hole 9001 are correspondingly connected.

[0037] As an example, the riveting driver 231 is implemented to include a cylinder.

[0038] Preferably, the riveting component 23 further includes at least one adsorption member 233, which is installed at the end of the riveting column 232 close to the riveting die 22, so that when the riveting column 232 moves, the rivet nut 800 is passed through the screw hole by the riveting head 2321 and is sucked by the adsorption member 233, thereby fixing the initial state of the rivet nut 800, so that the rivet nut 800 corresponds to the rivet hole 9001 of the plate 900 on the riveting die 22.

[0039] As an example, the adsorption member 233 is implemented to include a magnet.

[0040] It can be understood by those skilled in the art that before the riveting operation, the plate 900 is placed on the riveting die 22 and the rivet hole 9001 corresponds to the die hole 2201, and the protrusion 221 of the riveting die 22 abuts against the plate 900 from the bottom to form the wall of the rivet hole 9001; at this time, the rivet nut 800 is sucked by the adsorption member 233 in the manner that the screw hole is passed through by the rivet head 2321, so that when the riveting driving member 231 drives the rivet column 232, the rivet nut 800 follows the rivet column 232 to move and abut against the plate 900; because the oblique convex portion 801 of the rivet nut 800 is formed by the outward extension of the inner wall forming the screw hole and can extend into the rivet hole 9001, when the rivet nut 800 abuts against the plate 900, the oblique convex portion 801 passes through the rivet hole 9001 and abuts against the protrusion 2 21, the outer part of the angle space 8001 is covered by the plate 900; at this time, the rivet column 232 drives the rivet nut 800 to continue to move, and the rivet nut 800 and the main part of the plate 900 are pressed and fit against the riveting die 22. Since the height of the part of the protrusion 221 close to the die hole 2201 is greater than the height of the part away from the die hole 2201, the oblique protrusion 801 of the rivet nut 800 first abuts against the high end of the protrusion 221, thereby causing the oblique protrusion 801 of the rivet nut 800 to tilt in the direction away from the die hole 2201; at the same time, when the plate 900 is pressed toward the angle space 8001 by the protrusion 221 of the riveting die 22, the part of the plate 900 supported by the protrusion 221 will be squeezed obliquely toward the angle center of the angle space 8001 under the action of pressure. In this way, the main part of the rivet nut 800 and the oblique protrusion 801 clamp the plate 900 to form the side wall of the rivet hole 9001, thereby fixing the rivet nut 800 and the plate 900. Due to the guidance of the protrusion 221, the part of the plate 900 with reduced thickness will be squeezed into the angle space 8001 instead of extending to the side, that is, no depression or bending will occur on the side close to the rivet nut 800 on the surface.

[0041] Preferably, the riveting device further comprises a positioning member 30, the positioning member 30 comprising a positioning member 31 and an elastic member 32, wherein the elastic member 32 is installed in the die hole 2201, the positioning member 31 is slidably installed in the die hole 2201 and one end of the positioning member 31 presses against the elastic member 32, and when the elastic member 32 is in a normal state, the end of the positioning member 31 away from the elastic member 32 protrudes from the die hole 2201 by a predetermined distance. The positioning member 31 is adapted to the rivet hole 9001, and when the plate 900 is placed on the riveting die 22, the rivet hole 9001 is passed through by the positioning member 31 to determine the position, so as to avoid the rivet nut 800 not corresponding to the rivet hole 9001.

[0042] As an example, the positioning member 31 is implemented to include a positioning member. The elastic member 32 is implemented to include a spring.

[0043] It can be understood that, in the process where the rivet column 232 is driven by the rivet driving member 231 to drive the rivet nut 800 to move and make the rivet nut 800 abut against the plate 900, the positioning member 31 will be pressed by the rivet head 2321 and slide in the direction away from the rivet column 232 in the die hole 2201, and the elastic member 32 is compressed at this time; when the rivet nut 800 completes riveting and the rivet column 232 is away from the plate 900, the plate 900 and the rivet nut 800 can be removed, and at this time the elastic member 32 resets and generates elastic force to make the positioning member 31 move and extend out of the die hole 2201, so that the positioning member 31 can position the next plate 900.

[0044] Preferably, the riveting device further includes a detection component 40, which includes a displacement detection component 41. The displacement detection component 41 is movably mounted on the riveting body 21, and the movement direction of the displacement detection component 41 is the same as the movement direction of the riveting column 232. The displacement detection component 41 is connected to the riveting column 232, and when the riveting column 232 moves, the displacement detection component 41 is driven to move synchronously. In this way, the movement distance of the riveting column 232 is always monitored by the displacement detection component 41. When the riveting column 232 moves too much or too little, the displacement detection component 41 can give a prompt so that the operator can mark the plate 900 and the rivet nut 800 being riveted at that time as unqualified products, thereby improving the quality of the product.

[0045] As an example, the displacement detecting member 41 is implemented as a displacement sensor with an indicator light.

[0046] Preferably, the inspection and control component 40 also includes a pressure detection component 42, which is installed on the riveting column 232, and the pressure detection component 42 can detect and monitor the pressure changes of the riveting column 232, and prompt when the pressure exceeds a predetermined range, so that the operator can mark the riveted plate 900 and the rivet nut 800 as unqualified products, thereby improving the quality of the product.

[0047] As an example, the pressure detection component 42 is implemented to include a pressure sensor with an indicator light.

[0048] Preferably, the inspection and control component 40 also includes a motion capture component 43, which is installed on the riveting body 21, and the capture lens of the motion capture component 43 is facing the movement path of the riveting head 2321 of the riveting column 232. When the movement of the riveting head 2321 does not comply with the predetermined procedure, the motion capture component 43 will prompt so that the operator can mark the riveted plate 900 and the rivet nut 800 as unqualified products, thereby improving the quality of the product.

[0049] As an example, the motion capture component 43 is implemented to include a motion capture device with an indicator light.

[0050] Preferably, the moving direction of the rivet pressing column 232 is set to move vertically up and down. The number of the rivet holes 9001 on the plate 900 is at least two, and the plurality of rivet holes 9001 are all located in the same straight line. The rivet pressing device also includes a plate clamping and moving device 50, which includes a clamping member 51, a lifting member 52 and a transverse member 53. The clamping member 51 includes two clamping members 511 and a clamping drive member 512, wherein the two clamping members 511 are connected to the clamping drive member 512 so as to be drivable to move closer to or away from each other, so that the two clamping members 511 can clamp the plate 900.

[0051] The clamping member 51 is connected to the lifting member 52 so as to be driven to lift and lower, and the lifting member 52 is connected to the transverse member 53 so as to be driven to move laterally, and the transverse direction of the transverse member 53 is set to be the same as the straight line direction between the multiple rivet holes 9001 on the plate 900.

[0052] As an example, the lifting member 52 is implemented as a pneumatic cylinder, and the traverse member 53 is implemented as an electric cylinder.

[0053] It can be understood that the two clamping members 511 can clamp the plate 900 and be driven to rise and fall by the lifting member 52 to place the plate 900 in a fixed position on the riveting die 22; when one of the rivet holes 9001 on the plate 900 completes the riveting operation, the two clamping members 511 clamp the plate 900 and are driven to rise by the lifting member 52, and then the transverse member 53 drives the clamping member 51 and the lifting member 52 to move laterally as a whole, so that the other rivet hole 9001 on the plate 900 is directly above the positioning member 31, and then the clamping member 51 is driven to descend by the lifting member 52 to complete the clamping and movement of the plate 900, which is convenient for the operator to operate.

[0054] It is worth mentioning that, usually, the clamping member 51 is connected to other devices via a line. In order to prevent the line from being affected when the clamping member 51 moves, the plate clamping and moving device 50 is provided with a bendable and deformable track to fix the line.

[0055] Preferably, the inspection and control assembly 40 further includes a controller 44, which is communicatively connected to the displacement detection member 41, the pressure detection member 42, and the motion capture member 43, and is controllably connected to the clamping drive member 512, the lifting member 52, and the transverse member 53. When the displacement detection member 41, the pressure detection member 42, or the motion capture member 43 detects an error in the riveting operation of the riveting column 232, the controller 44 can control the plate clamping and moving device 50 to move the plate 900 to an unqualified area for placing unqualified products; when the riveting operation of the riveting column 232 is normal, the controller 44 controls the plate clamping and moving device 50 to move the plate 900 to a qualified area for placing qualified products.

[0056] Preferably, the riveting device further includes a nut supply device 60, which includes a placement platform 61, which is installed between the riveting column 232 and the riveting die 22. The placement platform 61 includes a placement body 611, at least one placement plate 612, and at least one return torsion spring 613, wherein the placement body 611 is installed on the riveting body 21. The placement body 611 forms a placement groove 61101 on the axis of the riveting column 232, and the placement plate 612 is rotatably mounted in the placement groove 61101 toward the riveting die 22, thereby blocking the placement groove 61101. One end of the return torsion spring 613 abuts the placement plate 612, and the other end abuts the placement body 611, so that under normal circumstances, the placement plate 612 is supported by the return torsion spring 613 and can be used to place the rivet nut 800.

[0057] It can be understood that, under normal circumstances, the rivet nut 800 is placed on the placement plate 612. At this time, the rivet nut 800 is on the axis of the rivet column 232. When the rivet column 232 is driven to move, the screw hole of the rivet nut 800 is passed through by the rivet head 2321 of the rivet column 232 and pressed against the placement plate 612 under the drive of the rivet column 232. At this time, the return torsion spring 613 is compressed, and the placement plate 612 moves to the left. The rivet die 22 flips over to open the placement slot 61101, and the rivet nut 800 can be driven by the rivet column 232 to pass through the placement slot 61101 and press against the rivet die 22. When the rivet operation is completed, the rivet column 232 returns to its original position so that the placement plate 612 is no longer pressed. At this time, the return torsion spring 613 returns to its original position and drives the placement plate 612 to block the placement slot 61101, allowing the next rivet nut 800 to be placed. In this way, the rivet nut 800 does not need to be placed on the rivet head 2321 by the operator, preventing the rivet nut 800 from being offset and out of alignment with the rivet die 22.

[0058] Preferably, the placement body 611 forms a straight path 61102 with an opening facing the placement slot 61101. The nut supply device 60 includes a pushing member 62 installed in the straight path 61102 of the placement body 611. The pushing member 62 includes a pushing rod 621 and a driving member 622. The pushing rod 621 is movably connected to the driving member 622. When the self-clinching nut 800 is placed in the opening of the straight path 61102, the pushing rod 621 is driven by the driving member 622 to move and push the self-clinching nut 800 into the placement slot 61101. In this way, the operator does not need to carefully place the self-clinching nut 800 on the placement plate 612, and manual operation errors can be avoided.

[0059] Preferably, the placement body 611 forms a curved channel 61103 adjacent to the straight channel 61102. One end of the curved channel 61103 communicates with the outside world, while the other end communicates with the straight channel 61102. The curved channel 61103 faces the straight channel 61102 and is positioned adjacent to the inner wall of the placement slot 61101. The nut supply device 60 further includes a supply member 63 connected to the curved channel 61103 and configured to supply the self-clinching nut 800 to the curved channel 61103. It will be appreciated that the self-clinching nut 800 is transported by the supply member 63 through the curved channel 61103 into the straight channel 61102, and after being stopped by the inner wall of the straight channel 61102, is pushed by the push rod 621 into a predetermined position within the placement slot 61101.

[0060] Preferably, the supply member 63 includes a feed member 631, a vibration disk 632, and a blowing member 633, wherein the feed member 631 is connected to the bend 61103 of the placement body 611 through a pipe, and the vibration disk 632 is connected to an end of the feed member 631 away from the placement body 611, so that the self-clinching nuts 800 pass through the vibration disk 632 and enter the feed member 631 in an orderly manner. The blowing member 633 is installed on the feed member 631 and blows each of the self-clinching nuts 800 entering the feed member 631 toward the placement body 611 in sequence, thereby automatically completing the supply of the self-clinching nuts 800.

[0061] As an example, the blowing member 633 is implemented to include a pipe connected to a blowing device.

[0062] Preferably, the riveting equipment also includes an automatic loading device 70, and the automatic loading device 70 includes a loading component 71 and a suction component 72, wherein the loading component 71 and the suction component 72 are both installed on the equipment body 10, and the loading component 71 is used to place multiple plates 900 and move the plates 900 to a predetermined position.

[0063] As an example, the loading component 71 is implemented as a conveyor belt.

[0064] Preferably, the loading assembly 71 includes a loading drive member 711 and a movable member 712, the movable member 712 is rotatably connected to the loading drive member 711, and the movable member 712 is used to place a plurality of the plates 900 so that the plates 900 can be driven by the movable member 712 to rotate under the drive of the loading drive member 711.

[0065] As an example, the loading driving member 711 is implemented to include a driving motor, and the moving member 712 is implemented to include a rotating disk.

[0066] The suction assembly 72 includes a suction member 721, a vertical moving member 722 and a horizontal moving member 723, wherein the suction member 721 is drivably connected to the vertical moving member 722, and the vertical moving member 722 is drivably connected to the horizontal moving member 723, so that the suction member 721 can move in the vertical and horizontal directions under the drive of the vertical moving member 722 and the horizontal moving member 723, and the suction member 721 is installed at a predetermined height above the moving member 712.

[0067] As an example, the suction member 721 is implemented as a suction plate with a suction cup. The suction member 721 changes the adsorption force between the suction cup and the plate 900 by means of air extraction and air intake, thereby sucking up or putting down the plate 900.

[0068] It is worth mentioning that, in general, the suction member 721 is connected to other devices via a circuit. In order to prevent the circuit from being affected when the suction member 721 moves, the suction assembly 72 is provided with a bendable and deformable track to fix the circuit.

[0069] It can be understood that when the plate 900 is driven to a predetermined position by the moving member 712, the suction member 721 moves downward to absorb the plate 900 and then moves upward, and then the suction member 721 moves horizontally to the moving path of the clamping member 511, so that the plate 900 is clamped by the clamping member 511, and then the plate 900 is placed on the riveting die 22 for riveting operation.

[0070] Preferably, the loading assembly 71 further includes at least two plate placing members 713 and at least two groups of fastening members 714, each group of fastening members 714 being mounted on the movable member 712 corresponding to one plate placing member 713, and each fastening member 714 being retractably inserted into the plate placing member 713 so that the plate placing member 713 can be quickly and detachably mounted on the movable member 712, and the plate placing member 713 is used to place the stacked plates 900. It is understandable that when one of the plate placing members 713 is moved to a predetermined position by the movable member 712, the operator can remove and install the other empty plate placing member 713 to fill it with plates 900, thereby continuing loading.

[0071] As an example, the fastening member 714 is implemented to include a spring pin.

[0072] Preferably, the plate placement member 713 includes a base 7131, a plurality of fixing posts 7132, and two handles 7133. The base 7131 is detachably mounted on the movable member 712. The plurality of fixing posts 7132 are vertically distributed above the base 7131 to form a space capable of placing a plurality of plates 900. Two handles 7133 are mounted on both sides of the base 7131 to facilitate the operator's removal and installation of the base 7131.

[0073] Preferably, the automatic loading device 70 further includes a lifting member 73, which is mounted on the equipment body 10. The lifting member 73 includes a lifting part 731 and a lifting driving part 732, wherein the lifting part 731 is connected to the lifting driving part 732 so as to be drivable and movable. The movable member 712 is formed with a lifting notch 71201, and the base 7131 of the plate placing member 713 is formed with a base notch 713101. Both the lifting notch 71201 and the base notch 713101 are adapted to the lifting member 731. The lifting member 731 is arranged directly below the lifting notch 71201 and the base notch 713101 when the movable member 712 moves to a predetermined position, so that the lifting member 731 can pass through the lifting notch 71201 and the base notch 713101 from below the movable member 712 and lift the plate 900 placed on the base 7131. In this way, the stacking thickness of the plates 900 is increased while the suction member 721 will not be able to suck up the plates 900 at the bottom.

[0074] Preferably, the riveting device further comprises a transfer identification device 80, which comprises a transfer body 81, a transfer moving assembly 82 and an identification member 83, wherein the transfer body 81 is mounted on the device body 10, and a portion of the transfer body 81 is located below the moving path of the suction member 721, and another portion is located to the side of the moving path of the clamping member 511. The transfer moving assembly 82 is mounted on the transfer body 81, and the transfer moving assembly 82 comprises a transfer table 821, at least one moving track 822 and a transfer driving member 823, wherein the moving track 822 is mounted on the transfer body 81, and the extension direction of the moving track 822 is set to extend from below the moving path of the suction member 721 to to the side of the moving path of the clamping member 511. The transfer platform 821 is connected to the transfer drive member 823 so as to be movably driven along the movable track 822, so that the plate 900 sucked by the suction member 721 can be placed on the transfer platform 821 and moved toward the clamping member 511 through the transfer platform 821. A clamping groove 82101 is formed on the portion of the transfer platform 821 near the clamping member 511. The clamping groove 82101 is adapted to fit the clamping member 511, so that the clamping member 511 clamps the plate 900 from both the upper and lower sides.

[0075] A main body identification hole 8101 is formed in the portion of the transfer body 81 near the clamping member 511, and a transfer identification hole 82102 is formed in the center of the transfer platform 821. When the transfer platform 821 moves to a position close to the clamping member 511, the main body identification hole 8101 and the transfer identification hole 82102 are located in the same vertical direction. The identification member 83 is mounted on the transfer body 81 and is located below the main body identification hole 8101. The identification member 83 can identify the front and back of the plate 900. In this way, when the plate 900 is placed on the transfer platform 821 by the suction member 721 and moved close to the clamping member 511, the identification member 83 can pass through the main body identification hole 8101 and the transfer identification hole 82102 to identify the front and back of the plate 900, thereby preventing the clamped plate 900 from flipping over and causing errors in the riveting operation.

[0076] As an example, the intermediate driving member 823 is implemented to include a cylinder.

[0077] Preferably, holes are provided on the transfer table 821 for installing the positioning member 30, so that when the plate 900 is placed on the transfer table 821 by the suction member 721 of the automatic loading device 70, the positioning member 30 can ensure that the position of the plate 900 on the transfer table 821 is fixed, thereby preventing the plate 900 from deviating from the transfer identification hole 82102 and becoming unrecognizable.

[0078] Preferably, the riveting device further includes a collection component 90, which is mounted on the device body 10. The collection component 90 includes an unqualified collection component 91 and a qualified collection component 92, and the unqualified collection component 91 and the qualified collection component 92 are both arranged at least partially below the moving path of the clamping member 51. The unqualified collection component 91 is used to collect unqualified products, and the qualified collection component 92 is used to transport qualified products away from the riveting device. It can be understood that once during the riveting process, the inspection and control component 40 or the identification component 83 identifies that there is a problem with the plate 900, the clamping member 511 will move the plate 900 to the unqualified collection component 91 under the control of the controller 41, and only the plate 900 with a smooth process will be moved to the qualified collection component 92.

[0079] As an example, the unqualified collection member 91 is implemented as a collection box, and the qualified collection member 92 is implemented as a conveyor belt.
