Description

Technical Field

[0001] The present invention relates to the technical field of automatic feeding, and specifically to a rivet bolt feeding structure and a full-automatic riveting device. Background Art

[0002] Riveting, also known as rivet connection or rivet bolt connection, is a process of connecting two or more parts together by using rivet bolts (also known as blind rivets). A rivet bolt is a hollow rivet with a prefabricated nail core. By using a special tool to break the nail core, the tail of the rivet expands, thus tightly fixing the parts together.

[0003] When a rivet bolt is installed, a riveting tool will clamp the pull ring of the nail core and apply a pulling force. As the pulling force increases, the nail core is gradually pulled into the nail body, and the tail of the nail body will expand due to the pulling of the nail core, thus tightly clamping the connected parts. When the nail core is broken, the rivet bolt is installed, and the parts are firmly connected together.

[0004] Therefore, in order to ensure that the riveting gun can be smoothly connected to the rivet bolt, it is necessary to clamp and position the rivet bolt during the feeding of the rivet bolt. In the existing clamping, a clamping plate is usually used to provide the clamping force for the rivet bolt to laterally clamp the rivet bolt. However, this method cannot ensure that the rivet bolt is in a vertical state, which may cause misalignment between the riveting gun and the rivet bolt.

[0005] To avoid the above situation, it can be solved by the method of multi-point clamping. However, taking a hexagonal prism rivet bolt as an example, when the clamping plate abuts against two symmetrically located edges of the rivet bolt, if the line connecting the two edges is perpendicular or nearly perpendicular to the clamping plate, the thrust provided by the clamping plate to the rivet bolt cannot overcome the resistance generated by the edges, making the rivet bolt unable to adaptively correct its posture, resulting in the rivet bolt unable to be positioned to the required position. Summary of the Invention

[0006] The purpose of the present invention is to provide a rivet bolt feeding structure and a full-automatic riveting device to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: A rivet bolt feeding structure includes a vibrating feeding tray and a conveying plate. A guide rail is provided on the conveying plate, and further includes: A lateral clamping mechanism, which includes symmetrically arranged clamping plates that are rotatable to adjust the clamping angle of the rivet bolt.

[0008] As a further solution of the present invention: it further includes: The yaw control mechanism is used to drive the clamping plate to rotate so as to adjust the clamping angle of the clamping plate. It includes a rotating rod fixed to the clamping plate and two symmetrically arranged movable sleeves sleeved on the rotating rod for driving the rotating rod to perform forward and reverse rotations in sequence, so as to drive the clamping plate to automatically return to the correct position after adjusting the angle of the rivet bolt.

[0009] As a further solution of the present invention: a guiding groove is provided on the circumferential outer wall of the rotating rod, and a first limiting block slidably matched with the guiding groove is arranged in the movable sleeve. Among them: the guiding groove includes a vertical groove, a first spiral groove, and a second spiral groove opened on the circumferential outer wall of the rotating rod. Two ends of the second spiral groove are respectively connected to one end of the vertical groove and the first spiral groove, and the other end of the first spiral groove is connected to the vertical groove.

[0010] As a further solution of the present invention: a third spiral groove is further formed on the rotating rod, and a second limiting block slidably matched with the third spiral groove is arranged in a follower ring sleeved on the rotating rod; An elastic guiding member is further arranged between the movable sleeve and the follower ring. The elastic guiding member cooperates with the third spiral groove and the second limiting block on the follower ring to drive the rotating rod to have a torsional force relative to the movable sleeve.

[0011] As a further solution of the present invention: it further includes a receiving plate for supporting the rotating rod. The receiving plate is slidably connected to a workbench for receiving a vibrating feeding tray. A first spring is sleeved on the rotating rod between the movable sleeve and the receiving plate; A first connecting rod is hinged to the movable sleeve, and one end of the first connecting rod away from the movable sleeve is hinged to a pushing member.

[0012] As a further solution of the present invention: the pushing member includes a movable plate and a sliding sleeve fixedly connected to the movable plate. The first connecting rod is hinged to the sliding sleeve, and the movable plate is driven by a telescopic driving member installed on the workbench to move.

[0013] As a further solution of the present invention: a support column is installed on the workbench. The support column sequentially penetrates through the movable plate, the sliding sleeve and the receiving plate, and is slidably connected to the movable plate, the sliding sleeve and the receiving plate.

[0014] As a further solution of the present invention: it further includes a lateral clamping assembly arranged on the clamping plate, including two inclined plates arranged symmetrically. When the clamping plate rotates, the two inclined plates move towards each other or in opposite directions to perform lateral clamping or releasing lateral clamping actions on the rivet bolt.

[0015] As a further solution of the present invention: a chute is formed on the clamping plate, and two sliding blocks respectively fixed to the two inclined plates are slidably installed in the chute; A connecting seat is rotatably installed on the movable sleeve, and the connecting seat is hinged to the sliding block through a second connecting rod hinged thereto.

[0016] A full-automatic riveting device includes the above-mentioned riveting bolt feeding structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can realize multi-directional positioning and clamping of the riveting bolt through the cooperation of the inclined plate and the clamping plate, ensuring that the riveting gun can smoothly screw into the riveting bolt. The two clamping plates are controlled to approach each other by the transverse clamping mechanism to clamp two side walls of the riveting bolt, and the two inclined plates are controlled to approach each other by the lateral clamping assembly to clamp the other side walls of the riveting bolt. At the same time, the yaw adjustment mechanism can also adjust the clamping direction of the clamping plate to achieve the effect of clamping and positioning the riveting bolt with different yaw angles.

[0018] By controlling the movement of the yaw adjustment mechanism, the rotating rod is rotated by a certain angle, thereby adjusting the angle between the clamping plate and the riveting bolt, changing the direction of the clamping force generated by the clamping plate, and further reducing the angle between the clamping plate and the adjacent vertical side of the edge. As the angle decreases, the resistance generated by the edge gradually decreases until the resistance is less than the thrust provided by the clamping plate. Under the thrust of the clamping plate, the posture of the riveting bolt is corrected, thereby achieving the effect of clamping and positioning the riveting bolt at different angles.

[0019] The pre-thrust of the second spring and the interaction between the second limit block and the third spiral groove ensure that when the movable sleeve moves away from the limit ring, the first limit block can smoothly enter the first spiral groove. At the same time, during the clamping process of the clamping plate, the compression amount of the first spring will gradually increase, thereby ensuring that the clamping force provided by the clamping plate can meet the clamping requirements and guaranteeing the stability and reliability of the riveting bolt during the clamping process.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0033] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a rivet bolt feeding structure includes: A workbench 1, and a vibrating feeding tray 2 and a fixing plate 4 fixed on the workbench 1. A conveying plate 3 is fixed on the vibrating feeding tray 2, and a guide rail 301 is provided on the conveying plate 3; It further includes: A lateral clamping mechanism, the lateral clamping mechanism includes clamping plates 8 arranged symmetrically, and the clamping plates 8 are rotatable to adjust the clamping angle of the rivet bolt; It further includes a yaw control mechanism for driving the clamping plates 8 to rotate to adjust the clamping angle of the clamping plates 8.

[0034] Specifically, when loading the hexagonal riveting bolt, multiple riveting bolts can be placed on the vibrating loading tray 2. Under the action of the vibrating loading tray 2, the riveting bolts will be guided into the guide rail 301. To ensure that the riveting gun can smoothly screw into the riveting bolt, the riveting bolt needs to be clamped. Since the outer wall of the riveting bolt is hexagonal, only the vertical plane on its side needs to be clamped. At this time, under the action of the transverse clamping mechanism, the two clamping plates 8 are controlled to move towards each other until the clamping plates 8 are in contact with the riveting bolt. At this time, the transverse clamping mechanism continues to move, and the clamping angle of the clamping plates 8 is continuously adjusted through the yaw control mechanism, so that the included angle between the two symmetrically located edges where the clamping plates 8 are in contact with the riveting bolt decreases. Thus, through the thrust provided by the clamping plates 8 to the riveting bolt, the riveting bolt rotates itself, so that the vertical side of the riveting bolt moves to a position parallel and in contact with the clamping plates 8. Among them, since the vertical plane on the side of the riveting bolt may not be parallel to the clamping plates 8 during the movement process, and the riveting bolt itself may not be perpendicular to the workbench 1 either. Therefore, when the clamping plates 8 are in contact with the two symmetrically located edges of the riveting bolt, if the included angle between the vertical side adjacent to this edge and the clamping plates 8 is small, under the clamping force applied by the clamping plates 8, the riveting bolt will automatically adjust its posture so that its two symmetrically located vertical sides are parallel and in contact with the clamping plates 8. If the included angle between the vertical side adjacent to the edge of the clamping plates 8 is large, or the connection line of the two edges is perpendicular to the clamping plates 8, at this time, the force applied by the clamping plates 8 to the riveting bolt is difficult to control the automatic rotation of the riveting bolt. In this case, the yaw control mechanism comes into play, which can adjust the direction of the force exerted by the clamping plates 8 on the riveting bolt, so that the included angle between the clamping plates 8 and the vertical side of the riveting bolt decreases, thereby controlling the rotation of the vertical side of the riveting bolt to a position in contact with the clamping plates 8, realizing stable clamping of the riveting bolt.

[0035] Please refer to Figures 1 - 6 、 Figure 10 The yaw control mechanism includes a rotating rod 7 fixed to the clamping plate 8 and two symmetrically arranged movable sleeves 15 sleeved on the rotating rod 7 for driving the rotating rod 7 to perform forward and reverse rotations in sequence, so as to drive the clamping plate 8 to automatically return to the correct position after adjusting the angle of the riveting bolt.

[0036] When the clamping plate 8 is in contact with the riveting bolt, it can be divided into the following situations: The clamping plate 8 just contacts the two symmetrically located vertical sides of the riveting bolt. Under the action of the clamping plate 8, the riveting bolt is fixed between the clamping plates 8, achieving a stable clamping effect; The clamping plate 8 abuts against the edges at two symmetric positions of the rivet bolt, and the included angle between one of the vertical sides adjacent to the edge and the clamping plate 8 is small. In this case, the resistance generated by the edge is less than the thrust provided by the clamping plate 8. Therefore, under the action of the clamping force, the rivet bolt itself will deflect by a certain angle, so that its vertical side fits with the clamping plate 8, thereby realizing the clamping of the rivet bolt; Third, the clamping plate 8 abuts against the edges at two symmetric positions of the rivet bolt, and the included angles between the two vertical sides adjacent to the edges and the clamping plate 8 are both close to or equal to 60°. At this time, the thrust provided by the clamping plate 8 cannot overcome the resistance generated by the edges, resulting in a deviation in the clamping position of the rivet bolt.

[0037] A limiting ring 14 is also fixed on the rotating rod 7. When the movable sleeve 15 is in contact with the limiting ring 14, the two clamping plates 8 are in a state of not performing deflection.

[0038] A guiding groove is provided on the circumferential outer wall of the rotating rod 7, and a first limiting block 1501 that is slidably matched with the guiding groove is provided in the movable sleeve 15, wherein: the guiding groove includes a vertical groove 701, a first spiral groove 702, and a second spiral groove 703 formed on the circumferential outer wall of the rotating rod 7. Both ends of the second spiral groove 703 are connected to one end of the vertical groove 701 and the first spiral groove 702 respectively, and the other end of the first spiral groove 702 is connected to the vertical groove 701.

[0039] A third spiral groove 19 is also formed on the rotating rod 7, and a second limiting block 21 that is slidably matched with the third spiral groove 19 is provided in a follower ring 20 sleeved on the rotating rod 7; An elastic guiding member is further provided between the movable sleeve 15 and the follower ring 20. The elastic guiding member cooperates with the third spiral groove 19 and the second limiting block 21 on the follower ring 20 to drive the rotating rod 7 to have a torsional force relative to the movable sleeve 15.

[0040] Wherein, before the rivet bolt is clamped, the movable sleeve 15 and the limiting ring 14 are in abutment state, so that the first limiting block 1501 is located at the end of the stroke of the vertical groove 701 away from the second spiral groove 703, the second spiral groove 703 and the third spiral groove 19 have the same size and specification, and the second limiting block 21 is located at the end of the stroke of the third spiral groove 19 toward the vertical groove 701, so that the distance between the follower ring 20 and the limiting ring 14 is minimized, so that the elastic guide is in a compressed state, because the vertical groove 701 and the first limiting block 1501 have a locking effect on the rotating rod 7, so that the position of the follower ring 20 will not change, under the action of the elastic guide, the follower ring 20 has a tendency to move in the direction away from the limiting ring 14, and under the action of the second limiting block 21 and the third spiral groove 19, the rotating rod 7 has a tendency to rotate; When the rivet bolt needs to be clamped, at this time, the two clamping plates 8 move towards each other. After the clamping plates 8 abut against the rivet bolt, if the abutting state between the rivet bolt and the clamping plates 8 is the first or second state, the rivet bolt can be directly clamped under the action of the thrust of the clamping plates 8. If the abutting state between the rivet bolt and the clamping plates 8 is the third state, at this time, the clamping plates 8 no longer move, and the movable sleeve 15 starts to move along the length direction of the rotating rod 7 and moves in the direction away from the limit ring 14, so that the distance between the guide plate 24 and the follower ring 20 increases, so that the elastic force of the elastic guide is reduced, and the movable sleeve 1 The first limit block 1501 will also be driven to move along the vertical groove 701. When the first limit block 1501 moves to the position where the vertical groove 701 is connected with the first spiral groove 702, the rotating rod 7 is no longer locked, and the elastic guide is elastically released, driving the follower ring 20 to move, so that the second limit block 21 slides along the track of the third spiral groove 19, so that the rotating rod 7 rotates a certain angle to ensure that the first limit block 1501 smoothly enters the first spiral groove 702. The rotating rod 7 will drive the clamping plate 8 to deflect by a certain angle to change the clamping direction of the clamping plate 8 on the rivet bolt, thereby reducing the angle between the clamping plate 8 and the vertical side surface adjacent to the edge; When the thrust provided by the clamping plate 8 is greater than the resistance generated by the edge, the posture of the rivet bolt will automatically change until the vertical side of the rivet bolt fits against the clamping plate 8. When the first limit block 1501 moves to the connection position of the first spiral groove 702 and the second spiral groove 703, the movable sleeve 15 continues to move, so that the first limit block 1501 disengages from the first spiral groove 702 and enters the second spiral groove 703, so that after the clamping plate 8 clamps the rivet bolt, it swings toward the initial angle until the first limit block 1501 moves to the connection position of the second spiral groove 703 and the vertical groove 701, and the clamping plate 8 returns to the initial angle.

[0041] Among them, the elastic guiding member includes a guiding post 22 fixed to the follower ring 20. The guiding post 22 penetrates through a guiding plate 24 fixed on the movable sleeve 15 and is slidably connected to the guiding plate 24. A second spring 23 is sleeved on the guiding post 22 between the follower ring 20 and the guiding plate 24. The two ends of the second spring 23 are respectively abutted against the guiding plate 24 and the follower ring 20.

[0042] Please refer to Figures 3 - 5 and Figure 10 , it further includes a receiving plate 6 for supporting the rotating rod 7. The receiving plate 6 is slidably connected to a workbench 1 for receiving the vibrating feeding tray 2. A first spring 17 is sleeved on the rotating rod 7 between the movable sleeve 15 and the receiving plate 6; A first connecting rod 16 is hinged to the movable sleeve 15. One end of the first connecting rod 16 far from the movable sleeve 15 is hinged to a pushing member.

[0043] The pushing member includes a movable plate 11 and a sliding sleeve 13 fixedly connected to the movable plate 11. The first connecting rod 16 is hinged to the sliding sleeve 13. The movable plate 11 is driven to move by a telescopic driving member installed on the workbench 1.

[0044] A support column 5 is installed on the workbench 1. The support column 5 sequentially penetrates through the movable plate 11, the sliding sleeve 13 and the receiving plate 6, and is slidably connected to the movable plate 11, the sliding sleeve 13 and the receiving plate 6.

[0045] Preferably, the telescopic driving member includes but is not limited to a cylinder 12, a hydraulic cylinder or an electric telescopic rod. In this embodiment, the cylinder 12 is preferably selected.

[0046] Specifically, before clamping the rivet bolt, under the action of the cylinder 12, the movable plate 11 and the sliding sleeve 13 are located at the end of the stroke towards the fixed plate 4. The first spring 17 is in a compressed state, so that the movable sleeve 15 is in an abutting state with the limit ring 14. Under the action of the first connecting rod 16, the distance between the receiving plate 6 and the movable plate 11 is the largest, the distance between the clamping plate 8 and the fixed plate 4 is the smallest, and the distance between the two clamping plates 8 is the largest. When it is necessary to clamp and position the rivet bolt, at this time, the cylinder 12 works and controls the sliding sleeve 13 to move along the length direction of the support column 5 and move away from the fixed plate 4. The sliding sleeve 13 will drive the movable sleeve 15 to move through the first connecting rod 16, so as to push the receiving plate 6 to move synchronously with the sliding sleeve 13 through the rotating rod 7. The rotating rod 7 will also drive the clamping plate 8 to move, so that the distance between the two clamping plates 8 gradually decreases until the clamping plate 8 abuts against the rivet bolt.

[0047] Therefore, when the above-mentioned third situation occurs, since the position of the clamping plate 8 remains unchanged, when the cylinder 12 continues to move, the sliding sleeve 13 will continue to slide along the support column 5, reducing the distance between the sliding sleeve 13 and the receiving plate 6. The first connecting rod 16 controls the movable sleeve 15 to slide along the length direction of the rotating rod 7 and compresses the first spring 17. Under the action of the movable sleeve 15, the rotating rod 7 is controlled to rotate by a certain angle, thereby adjusting the angle between the clamping plate 8 and the rivet bolt, causing the direction of the clamping force generated by the clamping plate 8 to change, and then reducing the angle between the clamping plate 8 and the adjacent vertical side of the edge. As the angle decreases, the resistance generated by the edge gradually decreases until the resistance is less than the thrust provided by the clamping plate 8. Under the thrust of the clamping plate 8, the attitude of the rivet bolt is corrected, thus achieving the effect of clamping and positioning rivet bolts at different angles.

[0048] Through the flexible adjustment of the yaw control mechanism, the problem of clamping deviation caused by improper clamping angle can be effectively solved, ensuring that the rivet bolt is accurately clamped and positioned, and improving the reliability and stability of clamping.

[0049] It should be noted that before the rivet bolt is clamped, the first spring 17 is in a compressed state. Under the action of the cylinder 12, the movable sleeve 15 is in contact with the limit ring 14.

[0050] Preferably, the pre-thrust of the second spring 23 and the interaction between the second limit block 21 and the third spiral groove 19 ensure that when the movable sleeve 15 moves away from the limit ring 14, the first limit block 1501 can smoothly enter the first spiral groove 702. This action changes the clamping direction of the clamping plate 8, thereby achieving the effect of clamping and positioning the rivet bolt at any angle. During the clamping process of the clamping plate 8, the compression amount of the first spring 17 will gradually increase, thereby ensuring that the clamping force provided by the clamping plate 8 can meet the clamping requirements and ensuring the stability and reliability of the rivet bolt during the clamping process. When the riveting gun is screwed into the rivet bolt, the cylinder 12 controls the sliding sleeve 13 to move towards the initial position to control the movement of the movable sleeve 15 through the first connecting rod 16. The first spring 17 elastically releases, causing the movable sleeve 15 to move towards the limit ring 14 to control the first limit block 1501 to slide along the vertical groove 701. Since the elastic potential energy of the first spring 17 is always greater than the elastic potential energy of the second spring 23, during the reset process of the first limit block 1501, it will not enter the first spiral groove 702, ensuring that the angle of the clamping plate 8 will not deflect. When the movable sleeve 15 returns to the position where it abuts against the limit ring 14, the cylinder 12 continues to move until the clamping plate 8 returns to the initial position. Through the action of the first limit block 1501 and the vertical groove 701, it is possible to ensure that the angle of the clamping plate 8 will not deflect during the separation process of the clamping plate 8 and the rivet bolt, so as to ensure that the clamping plate 8 will not interfere with the rivet bolt.

[0051] Please refer to Figures 3 - 6 , further comprising a lateral clamping assembly arranged on the clamping plate 8, including two inclined plates 10 arranged symmetrically. When the clamping plate 8 rotates, the two inclined plates 10 move towards each other or in opposite directions to perform a lateral clamping or disengaging lateral clamping action on the rivet bolt.

[0052] A chute 801 is formed on the clamping plate 8, and two sliding blocks 9 respectively fixed to the two inclined plates 10 are slidably installed in the chute 801; A connecting seat 25 is rotatably installed on the movable sleeve 15, and the connecting seat 25 is hinged to the sliding block 9 through a second connecting rod 18 hinged thereto.

[0053] Furthermore, the included angle between the inclined plate 10 and the clamping plate 8 is 60°. Therefore, after the clamping plate 8 laterally clamps the rivet bolt, the inclined plate 10 can clamp two adjacent vertical sides of the rivet bolt. In the initial state, the movable sleeve 15 and the limit ring 14 are in contact with each other. Under the action of the second connecting rod 18, the distance between the two inclined plates 10 is maximized. When the clamping plate 8 laterally clamps the rivet bolt, it can only ensure that the rivet bolt is parallel to the clamping plate 8. At this time, the rivet bolt may still be in a non-vertical state. Therefore, when the movable sleeve 15 moves along the length direction of the rotating rod 7 and moves away from the limit ring 14, it drives the second connecting rod 18 to move, thereby driving the two sliding blocks 9 to move towards each other, so that the distance between the two inclined plates 10 is reduced. During this process, the rotating rod 7 will rotate a certain angle, so that the direction of the clamping force provided by the clamping plate 8 to the rivet bolt is changed to correct the attitude of the rivet bolt. When the rotating rod 7 rotates towards the initial angle, it means that the vertical side of the rivet bolt is in contact with the clamping plate 8. At this time, the inclined plate 10 continues to move and controls the rivet bolt to move towards the center position of the clamping plate 8. When the movable sleeve 15 moves to the end of the stroke in the direction away from the limit ring 14, both inclined plates 10 will be in contact with the vertical side of the rivet bolt, thereby performing center positioning and angle alignment on the rivet bolt.
