[0011] At least one action part is press fitting action part, the press fitting mechanism is arranged on the action part, and the press fitting mechanism is pressed into ring in pipe body.

[0012] In the present application, the tooling plate one can rotate around its own axis, and since it is arranged with a plurality of tooling pins, each of which can be used for assembling the hollow rivet, that is, when a certain tooling pin rotates to the corresponding action part, the pipe body loading, ring loading and pressing can be realized on the tooling plate one, that is, through the rotation of the tooling plate one, the effective connection between independent processes is realized, so as to achieve the production requirements of reducing cost and improving efficiency through high integration.

[0013] Preferably, the pipe body loading mechanism comprises:

[0014] A staggered turntable for receiving the pipe body, the staggered turntable can rotate around its own axis, the rotation plane of the staggered turntable is perpendicular to the rotation plane of the tooling plate one, and the staggered turntable is provided with a plurality of receiving grooves along its outer circumference.

[0015] The axis of the receiving groove and the outer circumference where the receiving groove is located are perpendicular, so that during the rotation of the staggered turntable, when the receiving groove is located at the top of the staggered turntable, the clamping mechanism of the corresponding action part can well load the pipe body onto the tooling pin moving to the corresponding position of the tooling plate one.

[0016] Preferably, the pipe body loading mechanism further comprises:

[0017] A detection element one for detecting whether the stepped end of the pipe body in the receiving groove is located at a preset position; and

[0018] A recovery funnel, the recovery funnel is arranged below the staggered turntable.

[0019] For the pipe body, its posture should be adapted to the subsequent pressing, so it is necessary to detect the posture of the pipe body, and through the detection element one, the position of the stepped end can be judged, if it is inconsistent with the preset position, the clamping mechanism will not clamp the pipe body, and the pipe body will fall out by its own gravity, and then be recovered through the recovery funnel, so as to ensure the pressing effect.

[0020] Preferably, the ring loading mechanism comprises:

[0021] A mounting seat, the mounting seat is provided with a preset sliding surface one;

[0024] Wherein, an elastic member 1 is provided between the ejector pin and the active member.

[0025] The ejector pin can achieve the placement and avoidance of the ring through the sliding of the active part, so that the ring can be normally placed on the slider, and the ring can follow the movement of the active part. During the movement of the active part, since the ejector pin slides to cooperate with the active part and the mounting seat, the ejector pin can be hidden and extended in the active part.

In other words, when the embedded structure exists, the ring can be well placed, and the placement and positioning are achieved by the embedded structure. When the active member moves in the reverse direction, the embedded structure is also eliminated due to the relative movement of the active member and the stopper, so that the ring is exposed from the stopper.

[0039] In the present application, the rotation of the jig disc three can be converted into the linear motion of the sliding block structure, and the structure is simple and compact; at the same time, the oscillation of the transmission shaft can be well realized by the connecting rod mechanism, so that the jig disc three can be oscillated, and the sliding block in the sliding block structure can realize reciprocating motion along the sliding groove, so that the clamping and grabbing mechanism / pressing and mounting structure can realize reciprocating motion on the jig disc two, and the oscillating arm mechanism can make the transmission shaft move linearly along the axis, so that the jig disc three and the jig disc two can both realize lifting relative to the jig disc one, thereby meeting the actual action requirements of the corresponding action part.

[0040] Preferably, the present application further comprises:

[0041] a carrier, the connecting rod mechanism being slidingly matched with the carrier.

DETAILED DESCRIPTION

[0061] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0062] like Figures 1 to 6 As shown, a blind rivet press-fitting device includes a tool plate 1 and a tool plate 2; the tool plate 1 is evenly provided with a plurality of tool nails 3 along its circumference, and the tool plate 1 can rotate around its axis; the tool plate 2 2 and the tool plate 1 are coaxially arranged, and have a plurality of action parts, at least some of which are provided with a clamping mechanism 4; wherein, a tube feeding mechanism 100, a ring feeding mechanism 200, and a press-fitting mechanism 300 are provided along the circumference of the tool plate 1; wherein at least one action part is a tube body 500 feeding action part, and one side of the action part A tube body feeding mechanism 100 is provided, and the tube body 500 is clamped onto the tooling nail 3 through the clamping mechanism 4 of the action part; at least one of the action parts is a ring 600 feeding action part, and a ring feeding mechanism 200 is provided on one side of the action part, and the ring 600 is clamped onto the tooling nail 3 through the clamping mechanism 4 of the action part, and is located above the tube body 500; at least one of the action parts is a pressing action part 203, and a pressing mechanism 300 is provided on the action part, and the pressing mechanism 300 presses the ring 600 into the tube body 500.

[0063] In the embodiment, according to the size of the tooling plate one 1 and / or the spacing of the tooling pins 3, a plurality of tooling pins 3 can be configured, and on this basis, according to the number of tooling pins 3, a set of mechanisms involved in the press-fitting process can be correspondingly configured, including the pipe body feeding mechanism 100, the ring feeding mechanism 200, and the press-fitting mechanism 300. For convenience of description, the embodiment is described in detail with one set of mechanisms. In the embodiment, the tooling plate two 2 remains stationary relative to the whole machine, and a plurality of action parts are configured on the tooling plate two 2, two of which are provided with the clamping and grabbing mechanism 4 to pick up the pipe body 500 and the ring 600 from the pipe body feeding mechanism 100 and the ring feeding mechanism 200 on the side of the tooling plate one 1 and place them on the tooling pin 3, and one of which is provided with the press-fitting mechanism 300 to press-fit the pipe body 500 and the ring 600, thereby making the pre-product. In the embodiment, according to the rotation direction of the tooling plate one 1, the pipe body 500 is first loaded, then the ring 600 is loaded, and then the press-fitting is performed, and finally the pre-product formed by press-fitting is transferred out of the tooling plate one 1. In some embodiments, the ring 600 can be loaded first, and then the pipe body 500 is loaded, but in this embodiment, due to the special structure of the pipe body 500 with a step inside, if the ring 600 is loaded first, it is not easy to take the pre-product after press-fitting from the tooling pin 3. Therefore, during the rotation of the tooling plate one 1, with a certain tooling pin 3 as a reference, it can pass through the pipe body feeding mechanism 100, the ring feeding mechanism 200, and the press-fitting mechanism 300 in turn and realize circulation, that is, after reaching the press-fitting mechanism 300 and taking the pre-product on the tooling pin 3, it moves from the press-fitting mechanism 300 to the pipe body feeding mechanism 100 along the preset rotation direction.

[0064] Therefore, the embodiment integrates the pipe body 500 feeding process, the ring 600 feeding process, and the press-fitting process, which can effectively reduce the transfer of parts and components, and well realize the connection of the mechanisms involved in each process, with high efficiency and low cost.

[0065] In the embodiment, the transfer mechanism one is used to transport the preform combined by the ring 600 and the tube 500 to the next process, and the transfer mechanism two 400 is used to transport the preform not transported by the transfer mechanism one out of the tooling disc one 1. The clamping force of the transfer mechanism two 400 is greater than that of the transfer mechanism one. In order to further provide the integration, the mechanism involved in each set of pressing process also includes the transfer mechanism one and the transfer mechanism two 400. Thus, in the assembly of the core-pulling rivet, according to the rotating direction of the tooling disc one 1, the tube 500 is first assembled, then the ring 600 is assembled, then the pressing is performed, and then the preform is transported to the next process by the transfer mechanism one. If the transportation is not completed, it indicates that the pressing causes the ring 600 and / or the tube 500 to be tightly matched with the tooling disc 3, at this time, the transfer mechanism two 400 is used to pick up the preform on the tooling disc 3. Since the clamping force of the transfer mechanism two 400 is greater than that of the transfer mechanism one, the preform is ensured to be clamped away from the tooling disc 3, and it is ensured that the tooling disc 3 does not interfere with the cyclic pressing when it is repeatedly used.

[0066] It should be noted that the transfer mechanism one and / or the transfer mechanism two 400 can be arranged on one side of the tooling disc one 1, or can be arranged on the tooling disc two 2. The specific arrangement mode can be adaptively configured according to the volume occupied by the equipment.

[0067] As Figure 4As shown, in the embodiment, the pipe body feeding mechanism 100 comprises a staggered turntable 5 for receiving the pipe body 500, the staggered turntable 5 can rotate around its own axis, the rotation plane of the staggered turntable 5 is perpendicular to the rotation plane of the tooling disc one 1, and the staggered turntable 5 is provided with a plurality of receiving grooves along its outer circumference. The pipe body 500 is transported to the staggered turntable 5 by the vibration machine one, and the posture of the pipe body 500 in the vibration machine one is that the axis is parallel to the transportation direction, so when the opening of a receiving groove of the staggered turntable 5 is docked with the vibration machine one, the pipe body 500 can be directly inserted into the receiving groove, and then the rotation of the staggered turntable 5 carries the pipe body 500 to the top of the staggered turntable 5, so that the axis of the pipe body 500 is perpendicular to the tooling disc one 1, and it should be noted that in order to facilitate the clamping of the pipe body 500 by the clamping and grabbing mechanism 4, a part of the pipe body 500 is located outside the receiving groove, so when the pipe body 500 is located at the top of the staggered turntable 5, the corresponding clamping and grabbing mechanism 4 can well clamp the pipe body 500 and then place the pipe body 500 on the tooling peg 3 on one side of the pipe body feeding mechanism 100. Further, since the pipe body 500 needs to meet the position of the stepped end to avoid that the subsequent transfer mechanism one or transfer mechanism two 400 cannot well clamp the preform to separate from the tooling peg 3, in the embodiment, the pipe body feeding mechanism 100 further comprises a detection element one 6 and a recovery hopper 7; the detection element one 6 is used to detect whether the stepped end of the pipe body 500 in the receiving groove is located at a preset position; and the recovery hopper 7 is arranged below the staggered turntable 5. The detection element one 6 is configured as a distance sensor or a vision sensor, which can judge the position of the stepped end, when the judged stepped end position is not the preset position, the corresponding clamping and grabbing mechanism 4 does not grab, and the staggered turntable 5 continues to rotate, and when the pipe body 500 is located below the staggered turntable 5, it falls to the recovery hopper 7 by its own gravity to realize recovery, when the judged stepped end position is the preset position, the corresponding clamping and grabbing mechanism 4 grabs the pipe body 500 and places it on the tooling peg 3, realizing the feeding of the pipe body 500 to the tooling peg 3.

[0068] As Figure 5As shown, in the embodiment, the ring loading mechanism 200 comprises a mounting seat 8, a driving part 9 and a ejector pin 10; the mounting seat 8 is provided with a preset sliding surface one 11; the driving part 9 has a cylinder mechanism 12 to drive its movement, so as to switch between a loading station away from the tooling disc one 1 and a material taking station close to the tooling disc one 1; the ejector pin 10 and the driving part 9 are vertically movably matched, the ejector pin 10 further slides with the preset sliding surface one 11 and the mounting seat 8, so as to be hidden inside the driving part 9 when the driving part 9 is located at the loading station, and to extend out of the driving part 9 to pass through the ring 600 when the driving part 9 is switched to the material taking station; the ejector pin 10 and the driving part 9 are provided with an elastic part one 13. The ring 600 is conveyed to the ring loading mechanism 200 by a vibration machine two, the driving part 9 is pushed by the cylinder mechanism 12 to realize sliding with the mounting seat 8, the cylinder mechanism 12 drives the driving part 9 to switch to the loading station, so that the vibration machine two loads the ring 600 to the driving part 9, then the cylinder mechanism 12 drives the driving part 9 to move reversely to the material taking station, so that the corresponding clamping mechanism clamps the ring 600 to the tooling nail 3, and the ring 600 and the tube body 500 on the same tooling nail 3 follow the tooling disc one 1 to rotate to the pressing mechanism 300, and the pressing mechanism 300 completes pressing. In the above process, when the driving part 9 moves towards the loading station, the ejector pin 10 is recovered to be hidden inside the driving part 9 to avoid interfering with the ring 600 loading, when the driving part 9 moves towards the unloading station, the ejector pin 10 extends out to pass through the ring 600, so as to realize positioning of the ring 600 and avoid that the clamping mechanism 4 cannot stably clamp the ring 600. The preset sliding surface one 11 has an inclined surface, the ejector pin 10 falls on the preset sliding surface one 11 by gravity and keeps abutting against the preset sliding surface one 11 through the elastic part one 13, so as to ensure stable movement of the ejector pin 10 in the process of movement of the driving part 9. Further, in order to avoid that the ejector pin 10 cannot pass through the ring 600 well, the ring 600 needs to be placed on the driving part 9 in a positioning manner, therefore, the mounting seat 8 is further provided with a preset sliding surface two 14; the ring loading mechanism 200 further comprises a stopper 15, the stopper 15 has a first supporting body 16 vertically arranged, the first supporting body 16 and the driving part 9 slide with each other and cooperate with the preset sliding surface two 14 through an elastic part two 17, the stopper 15 is further provided with a limiting groove parallel to the first supporting body 16, the driving part 9 is provided with a second supporting body 18 matched with the limiting groove; the ejector pin 10 and the second supporting body 18 slide with the driving part 9.Specifically, the free end of the second supporting body 18 of the driving member 9 is configured as a placement part for placing the ring 600 transferred by the vibration machine II in the vertical direction, and the second supporting body 18 and the limiting groove are in sliding connection, when the driving member 9 is located in the feeding station, the placement part is located at the bottom of the limiting groove, and the placement of the ring 600 is positioned through the two opposite side walls of the limiting groove, so that the relative position of the ring 600 and the stop block 15 is maintained when the placement part moves along the limiting groove, so that when the driving member 9 is located in the discharging station, the second supporting body 18 gradually fills the limiting groove, that is, the ring 600 is exposed from the limiting groove, so as to meet the clamping requirement of the clamping mechanism 4. The first supporting body 16 provided by the stop block 15 is kept against the second predetermined sliding surface 14 by the second elastic member 17, so that the stop block 15 keeps stable movement during the sliding process of the driving member 9.

[0069] In the embodiment, at least a part of the action part is provided with a sliding mechanism 19, at least a part of the sliding mechanism 19 is connected with the clamping mechanism 4, and the press-fitting mechanism 300 is arranged on one of the sliding mechanisms 19. The arrangement of the sliding mechanism 19 can drive the clamping mechanism 4 and the press-fitting mechanism 300 to move linearly, so as to more conveniently realize the material clamping and press-fitting, and the structure is simple and easy to realize. The sliding mechanism 19 is specifically a sliding block and sliding rail mechanism.

[0070] As Figure 3As shown, in this embodiment, it is necessary to realize the movement of the sliding mechanism 19. In order to save assembly space and reduce costs, it also includes a tooling disc 3 20, a power source 21, a transmission shaft 22, a connecting rod mechanism 23 and a swing arm mechanism 24; the tooling disc 3 20 and the tooling disc 2 2 are coaxially arranged, and a slide block structure is provided between the tooling disc 3 20 and the sliding mechanism 19. The tooling disc 3 20 rotates to make the sliding member 25 in the slide block structure slide along the slide; the power source 21 is provided with a cam 1 26 and a cam 27. Wheel two 27; the transmission shaft 22 is connected to the tooling disk two 2 and the tooling disk three 20; the cam one 26 is provided with a cam groove, one end of the connecting rod mechanism 23 cooperates with the cam groove, and the other end is hinged to the transmission shaft 22, so as to drive the tooling disk three 20 to reciprocate circumferentially along its axis through the power source 21; one end of the swing arm mechanism 24 cooperates with the outer circumference of the cam two 27, and the other end is hinged to the transmission shaft 22, so as to drive the tooling disk three 20 and the tooling disk two 2 to reciprocate axially along its axis through the power source 21. The chute is provided on the tooling plate 3 20, and the sliding member 25 is provided on the clamping mechanism 4 / pressing mechanism 300; when the tooling plate 3 20 rotates, the sliding member 25 moves along the chute, thereby realizing the linear motion of the clamping mechanism 4 / pressing mechanism 300, avoiding the use of a more expensive multi-joint robotic arm. On this basis, the cam 1 26 and the connecting rod mechanism 23 are adopted to realize the reciprocating swing of the tooling plate 3 20 through the cam 1 26, thereby realizing the reciprocating motion of the sliding member 25 along the chute, thereby realizing the clamping mechanism 4 / pressing mechanism 300. The reciprocating linear motion of mechanism 4 / pressing mechanism 300 meets the use requirements; in addition to meeting the driving requirements of tooling disk three 20, it is also necessary to realize the up and down movement of tooling disk two 2 to realize the pressing action of pressing mechanism 300, and the action of clamping mechanism 4 to place ring 600 / tube body 500 on tooling nail 3. Therefore, cam two 27 and swing arm mechanism 24 are provided. By driving cam two 27 to rotate, swing arm mechanism 24 realizes the up and down movement of transmission shaft 22 in a lever manner, thereby meeting the use requirements. Obviously, transmission shaft 22 and tooling disk three 20 are fixedly connected. In this embodiment, power source 21 is a motor, and sliding member 25 is configured as a roller. In this embodiment, it also includes a carrier 28, and the connecting rod mechanism 23 and carrier 28 are slidably matched. The assembly position provided by the carrier 28 can ensure the stability of the reciprocating rotation of the transmission shaft 22 due to the sliding fit between the connecting rod mechanism 23 and the carrier 28. The swing arm mechanism 24 in this embodiment includes a swing arm seat and a swing arm. The swing arm seat provides a hinge position for the swing arm, which can ensure the stability of the reciprocating up and down movement of the transmission shaft 22. Figure 6As shown, a bearing assembly 29 is positioned and assembled on the outside of the drive shaft 22. A bearing sleeve 30 is provided on the outside of the bearing assembly 29. One end of the bearing sleeve 30 abuts the outer ring of the bearing assembly 29, and the other end is connected to the second tooling plate 2. Specifically, a step is provided on the drive shaft 22, and the inner ring of the bearing assembly 29 is placed on the step. The inner ring of the bearing assembly 29 is locked with a lock nut 31. The bearing sleeve 30 is then press-fitted onto the outer ring of the bearing assembly 29 and fixed to the second tooling plate 2 via a fixing member to complete the assembly. In this manner, even if the drive shaft 22 rotates, the second tooling plate 2 can remain relatively stationary. Of course, in some cases, the second tooling plate 2 may rotate with it. In this case, a vertical guide post 32 can be provided. In this case, a fixed plate can be placed below the tooling plate, and the guide post 32 is fixed to the fixed plate. The guide post 32 passes through the second tooling plate 2 and slides with the second tooling plate 2 as the drive shaft 22 moves up and down, thereby better preventing the second tooling plate 2 from rotating.

[0071] Furthermore, in this embodiment, in order to avoid poor fit between the ring 600 and the tube body 500 caused by installation errors of the tooling nail 3, the press-fitting mechanism 300 includes a press-fitting seat and a press-fitting rod 33; the press-fitting seat is connected to the press-fitting action part 203; one end of the press-fitting rod 33 extends into the press-fitting seat and is axially limited by the press-fitting seat, and the press-fitting rod 33 has a radial displacement in the press-fitting seat. Figure 7 As shown, specifically. The mounting seat 8 includes a connecting member 34 and a mounting rod 35. The connecting rod and the press rod 33 are connected via the connecting member 34. The connecting member 34 has a convex ring arranged inward, so that the mounting rod 35 can press the column head of the press rod 33 against the convex ring, thereby achieving a stable connection of the press rod 33. When adjustment is required, during the installation process, the relative radial position between the press rod 33 and the connecting member 34 can be adjusted. That is to say, according to actual conditions, the center lines of the press rod 33 and the mounting rod 35 may not coincide. For the above embodiment, a blank action portion 206 can also be provided on the tooling disk 2 to form a redundant design. When the clamping mechanism 4, the press mechanism 300 or the sliding mechanism 19 fails, a targeted mechanism supplement can be performed to ensure the integrity of the assembly process of the blind rivet.

[0072] Thus, taking one of the tooling pins 3 on the tooling plate 1 as a reference, the tooling plate 2 has five action parts, which are a tube body 500 feeding action part, a ring 600 feeding action part, a pressing action part 203, a transfer mechanism one action part, and a transfer mechanism two 400 action part. In the above five action parts, a blank action part 206 can be added. The tube body 500 feeding action part is provided with a clamping mechanism 4 one, the ring 600 feeding action part is provided with a clamping mechanism 4 two, and the pressing action part 203 is provided with a pressing mechanism 300. The unloading action part one 204 is provided with a transfer mechanism one, and the unloading action part two 205 is provided with a transfer mechanism two 400. It can be known that, according to actual conditions, the transfer mechanism one can be arranged on one side of the unloading action part one 204, and the transfer mechanism two 400 can be arranged on one side of the unloading action part two 205.

[0073] Thus, the process path is as follows: the tooling pin 3 rotates with the tooling plate 1 to the tube body 500 feeding action part, stops, the clamping mechanism 4 one clamps the tube body 500 and places it on the tooling pin 3, then the tooling plate 1 rotates, so that the tooling pin 3 is located at the ring 600 feeding action part and stops, the clamping mechanism 4 two clamps the ring 600 and places it on the tooling pin 3, then the tooling plate 1 rotates, so that the tooling pin 3 is located at the pressing action part 203 and stops, the pressing mechanism 300 is driven to press the tube body 500 and the ring 600, forming a preform. Then the tooling plate 1 rotates, the tooling pin 3 penetrating the preform is located at the unloading action part one 204, so that the transfer mechanism one unloads, if the clamping force of the transfer mechanism one is insufficient, the tooling pin 3 continues to move to the unloading action part two 205, and is unloaded by the transfer mechanism two 400. At this time, the main part of the tooling pin 3 is in an optical axis state, and can be recycled with the tooling plate 1.

[0074] The above is only a preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application, and the protection scope of the present application should be limited by the scope defined in the claims. For ordinary skilled persons in the art, some improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
