Description

Technical Field

[0001] The invention relates to the technical field of metal riveting, and in particular to an integrated grabbing and riveting device for a sleeve. Background Art

[0002] Riveting can be divided into pull riveting, press riveting, spin riveting, self-piercing riveting, rivetless riveting, etc. Among them, press riveting refers to the process of connecting metal parts by deforming them under pressure. Compared with traditional welding processes, it has the advantages of more controllable quality and avoidance of welding damage.

[0003] Before riveting, the two parts (rivet and sleeve) need to be aligned, and then riveting is performed. In this process, the sleeve needs to be positioned first, then clamped and fixed, and finally the sleeve is transported to the corresponding position of the riveted part.

[0004] However, in the prior art, the positioning, clamping, fixing and conveying of the sleeve are mostly done manually, resulting in inaccurate positioning and low efficiency. Moreover, for metal parts that need to be riveted to the sleeve on both sides, the existing process is often to rivet one side in sequence; such a riveting process has the following defects: first, when the first side is riveted, the other side cannot be fixed, which affects the riveting effect; when the second side is riveted, the first side that has been riveted is subjected to pressure and the riveted structure is damaged; second, the efficiency of riveting the two sides separately in sequence is low, the effect is poor, and multiple operations are required, which is costly.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] 1. The second clamping member moves along the first direction to reduce or expand the distance between the first clamping part and the second clamping part to clamp or release the sleeve; the conveying assembly can move along the second direction to drive the clamping assembly to convey the sleeve to the riveted part. The clamping and conveying of the sleeve do not require manual operation, and the degree of automation is high; and the movement of the second clamping member changes the distance between it and the first clamping member, thereby achieving clamping or loosening, and the clamping force is moderate and the clamping and loosening actions are convenient.

[0022] Second, the first clamping portion is connected to the side wall of the sleeve, and the first clamping portion is arranged in an arc shape, which can increase the contact area between the first clamping portion and the sleeve, thereby making the first clamping portion clamp the sleeve more stably.

[0023] 3. The elastic sheet can protect the sleeve. When the second clamping member moves to the point where it just contacts the sleeve, it is difficult to stop the movement instantly and will often continue to move forward for a distance. If the elastic sheet is not provided, the second clamping member is likely to continue to move and then damage the sleeve; if the elastic sheet is provided, the movement of the second clamping member is just absorbed by the deformation of the second clamping member and will not damage the sleeve.

[0024] Fourth, the elastic sheet is arranged in an arc shape, which can increase the contact area between the second clamping member and the sleeve, thereby making the clamping of the sleeve more stable.

[0025] Fifth, the provision of the elastic sheet can also make the second clamping part clamp the sleeve more stably. During the clamping process of the second clamping part on the sleeve, the elastic sheet gradually deforms, thereby fitting with the side wall of the sleeve to the maximum extent, thereby making the clamping of the sleeve more stably.

[0026] 6. The sleeve can be positioned by setting a positioning column, so that the position of the sleeve is determined when it is transported to the riveted part; at the same time, the positioning column can move along the third direction, and when the sleeve is positioned, it will not affect the movement of the sleeve in the second direction.

[0027] 7. The first end plate and the second end plate are riveted at the same time, which improves the efficiency of pressure riveting, avoids the phenomenon that when one end is riveted, the other end cannot be fixed, resulting in poor riveting effect, and improves the riveting strength.

[0028] 8. Only one power mechanism is set on one side of the first end plate, and an elastic mechanism is set on one side of the second end plate. After riveting is completed, the elastic mechanism causes the second rivet head to withdraw from the second through hole, so that only one power component is set to automatically disengage the rivet heads at both ends. Compared with the setting of setting one power mechanism on both sides, power (cost) is saved.

[0029] 9. Notches are provided on the inner walls of the first through hole and the second through hole, so that the parts near the first through hole / the second through hole will not be squeezed against each other when riveting and deforming, thereby reducing the effect.

[0030] 10. Both the first rivet head and the second rivet head are provided with protrusions, and the protrusions are in contact with the notch. The protrusions divide the position near the first through hole / the second through hole into a plurality of deformation parts. During deformation, due to the isolation of the protrusions, the deformation parts will not interfere with each other. The combination of the protrusions and the notch can also play a guiding role, so that the movement direction of the first rivet head and the second rivet head is more accurate, so as to enhance the riveting effect.

[0051] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0052] Please refer to Figure 1-Figure 12 , the present invention discloses a sleeve grabbing and riveting integrated device, comprising: a clamping system 1000 and a riveting system 2000, wherein the clamping system 1000 can clamp the sleeve 600 and transport it to the riveting system 2000;

[0053] The clamping system 1000 includes: a clamping assembly 200, including: a first clamping member 210, which is arranged on one side of the sleeve 600 and has a first clamping portion 213; a second clamping member 220, which is arranged on the other side of the sleeve 600 and has a second clamping portion 223, and the second clamping member 220 can move along a first direction to reduce or increase the distance between the first clamping portion 213 and the second clamping portion 223 to clamp or release the sleeve 600; a conveying assembly 300, which is connected to the clamping assembly 200, and the conveying assembly 300 can drive the clamping assembly 200 to move along a second direction to convey the sleeve 600 to the riveted component 100; the first direction is perpendicular to the second direction;

[0054] Specifically, in this embodiment, the second clamping member 220 moves along the first direction, that is, moves toward or away from the first clamping member 210, thereby reducing or expanding the distance between the first clamping portion 213 and the second clamping portion 223 to clamp or release the sleeve 600; the conveying assembly 300 can move along the second direction to drive the clamping assembly 200 to convey the sleeve 600 to the rivet 100.

[0055] In the above process, the clamping and transportation of the sleeve 600 do not require manual operation, and the degree of automation is high; and the distance between the second clamping member 220 and the first clamping member 210 is changed by the movement of the second clamping member 220, thereby achieving clamping or loosening, and the clamping force is moderate and the clamping and loosening actions are convenient.

[0056] The first direction is perpendicular to the second direction. When the second clamping member 220 moves in the first direction, it will not drive it to move in the second direction; when the conveying assembly 300 moves in the second direction, the clamping assembly 200 will not move in the first direction, and the movements in the two directions will not interfere with each other.

[0057] The riveting system 2000 comprises: a riveting member 100, comprising a first end plate 110 and a second end plate 120 arranged at intervals, the first end plate 110 having a first through hole 111, the second end plate 120 having a second through hole 121, and the first through hole 111 and the second through hole 121 being arranged opposite to each other; the sleeve 600 being arranged between the first end plate 110 and the second end plate 120, and one end of the sleeve 600 being connected to the first end plate 110, and the other end of the sleeve 600 being connected to the second end plate 120; The radii of the first through hole 111 and the second through hole 121 are both smaller than the inner diameter of the sleeve 600; the riveting mechanism includes a first riveting head 410 and a second riveting head 420, the first riveting head 410 is located on the side of the first end plate 110 away from the second end plate 120, and the second riveting head 420 is located on the side of the second end plate 120 away from the first end plate 110; the outer diameters of the first riveting head 410 and the second riveting head 420 are both smaller than the inner diameter of the sleeve 600, and are both larger than the inner diameters of the first through hole 111 and the second through hole 121.

[0058] In the riveting system 2000, the first end plate 110 and the second end plate 120 are riveted at the same time, which improves the efficiency of the pressure riveting; and the two ends are riveted at the same time, which avoids the phenomenon that when one end is riveted, the other end cannot be fixed, resulting in poor riveting effect, thereby improving the riveting strength;

[0059] Preferably, the clamping assembly 200 also includes: a sliding plate 250, connected to the conveying assembly 300; a first guide rail 230, which is arranged on the sliding plate 250 along a first direction, the first clamping member 210 is fixed on the sliding plate 250, the second clamping member 220 is connected to the first guide rail 230, and the second clamping member 220 can slide relative to the guide rail along the first direction; a first driving cylinder 240, used to drive the second clamping member 220 to slide relative to the first guide rail 230; specifically, the second clamping member 220 slides relative to the first guide rail 230 to realize the movement of the second clamp along the first direction, thereby changing its distance from the first clamping member 210, and finally realizing the clamping and release of the sleeve 600. Furthermore, the first clamping member 210 includes a first clamping rod 211 and a first sliding rod 212 that are fixedly connected, the first clamping portion 213 is arranged on the first clamping rod 211, and the first sliding rod 212 is fixed on the sliding plate 250; the second clamping member 220 includes a second clamping rod 221 and a second sliding rod 222 that are fixedly connected, the second clamping portion 223 is arranged on the second clamping rod 221, and the second sliding rod 222 is slidingly connected to the first guide rail 230; when the second clamping member 220 slides until the first sliding rod 212 and the second sliding rod 222 are against each other, the continued sliding of the second clamping member 220 can be limited, thereby also serving as a protective sleeve 600.

[0060] The conveying assembly 300 includes: a fixed plate 310, on which a second guide rail 320 is provided, and the second guide rail 320 is arranged along a second direction, and the sliding plate 250 is slidably arranged on the second guide rail 320; a second driving cylinder 330, used to drive the sliding plate 250 to slide relative to the second guide rail 320.

[0061] Specifically, the sliding plate 250 slides relatively with the fixing plate 310 , so that the first clamping member 210 and the second clamping member 220 on the sliding plate 250 drive the sleeve 600 to move along the second direction, thereby transporting the sleeve 600 to the riveting member 100 .

[0062] Furthermore, a first limit block 311 and a second limit block 312 are provided on the fixed plate 310, and the first limit block 311 and the second limit block 312 are respectively located at the front and rear ends of the sliding plate 250. When the sliding block slides to abut against the first limit block 311 or the second limit block 312, the sliding plate 250 can be restricted from sliding further, thereby preventing the sliding block from sliding excessively.

[0063] Furthermore, the first limit block 311 can be used as a positioning block, and the position of the first limit block 311 along the second direction can be adjusted. When the sliding plate 250 moves along the second direction to abut against the first limit block 311, the sleeve 600 is just delivered to the rivet 100, that is, the length of the delivery stroke of the delivery assembly 300 is preset by the positioning block, and the sleeve 600 is accurately delivered; and the length of the delivery stroke of the delivery assembly 300 can be adjusted by adjusting the position of the first limit block 311 along the second direction to meet different usage requirements.

[0064] Preferably, the first clamping portion 213 is arranged in an arc shape and fits against the side wall of the sleeve 600 ; the second clamping portion 223 is provided with an elastic sheet 224 , the elastic sheet 224 is arranged in an arc shape and fits against the side wall of the sleeve 600 .

[0065] The first clamping portion 213 is connected to the side wall of the sleeve 600 . The first clamping portion 213 is arranged in an arc shape, which can increase the contact area between the first clamping portion 213 and the sleeve 600 , thereby making the first clamping portion 213 more stable in clamping the sleeve 600 .

[0066] The elastic sheet 224 is provided to protect the sleeve 600. Specifically, when the second clamping member 220 moves to just abut against the sleeve 600, it is difficult to stop the movement instantly, and it will often continue to move forward for a distance. If the elastic sheet 224 is not provided, the second clamping member 220 is likely to continue to move and then damage the sleeve 600; if the elastic sheet 224 is provided, the movement of the second clamping member 220 is just absorbed by the deformation of the second clamping member 220, and the sleeve 600 will not be damaged.

[0067] The elastic piece 224 is configured in an arc shape, so as to increase the contact area between the second clamping member 220 and the sleeve 600 , thereby making the clamping of the sleeve 600 more stable.

[0068] The elastic sheet 224 can also make the second clamping member 220 clamp the sleeve 600 more stably. Specifically, during the clamping process of the second clamping portion 223 clamping the sleeve 600, the elastic sheet 224 gradually deforms and fits the side wall of the sleeve 600 to the maximum extent, thereby making the clamping of the sleeve 600 more stable.

[0069] Preferably, the clamping system 1000 also includes: a positioning assembly 500, the positioning assembly 500 includes a positioning column 510 arranged between the first clamping portion 213 and the second clamping portion 223; a driving member 520, used to drive the positioning column 510 to move along a third direction to extend into or out of the sleeve 600; any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0070] Specifically, since the sleeve 600 cannot be positioned very accurately at the riveting position, the present embodiment sets the conveying assembly 300 to have a certain travel distance each time, so as long as the sleeve 600 is positioned before conveying, the position after conveying must be the preset position. Before conveying, the positioning column 510 is between the first clamping portion 213 and the second clamping portion 223, and then the sleeve 600 is placed between the first clamping portion 213 and the second clamping portion 223 to achieve positioning; then the second clamping portion 223 moves to clamp the sleeve 600, and after the sleeve 600 is clamped, the positioning column 510 moves along the third direction to exit the sleeve 600, so that the sleeve 600 can move along the second direction, and finally the sleeve 600 is conveyed to the riveted part 100 driven by the conveying assembly 300. After riveting is completed, the second clamping part 223 releases the sleeve 600, the conveying assembly 300 drives the clamping assembly 200 to withdraw from the riveted part 100, and the positioning column 510 moves along the third direction to reach between the first clamping part 213 and the second clamping part 223 to perform the next positioning-clamping-conveying of the sleeve 600.

[0071] In the above process, the positioning column 510 is provided to position the sleeve 600, so that the position of the sleeve 600 is determined when it is transported to the riveted part 100. At the same time, the positioning column 510 can move along the third direction, and when the sleeve 600 is positioned, the movement of the sleeve 600 in the second direction will not be affected.

[0072] Preferably, the positioning column 510 is cylindrical, and the side wall of the positioning column 510 is in contact with the inner wall of the sleeve 600; a guide portion is provided at one end of the positioning column 510, and the thickness of the guide portion gradually decreases from the center of the positioning column 510 to the end to form a guide surface 511.

[0073] The guide surface 511 is provided to correct the position error of the sleeve 600 with a guiding function when the positioning post 510 enters the sleeve 600, thereby achieving accurate positioning. At the same time, the guide surface 511 can also make the movement of the positioning post 510 entering the sleeve 600 smoother.

[0074] Preferably, the riveting system 2000 further includes: a power mechanism 430, which is disposed on a side of the first rivet head 410 away from the second rivet head 420, and is used to drive the first rivet head 410 to move in a direction toward or away from the first through hole 111;

[0075] The elastic mechanism 440 is arranged on the side of the second rivet head 420 away from the first rivet head 410, and the power mechanism 430 drives the first rivet head 410 to move to compress or release the elastic mechanism 440; the elastic mechanism 440 includes: a first fixed plate 441 and a second fixed plate 442, a guide column is arranged on the side of the first fixed plate 441 facing the second fixed plate 442, and a guide sleeve is arranged on the side of the second fixed plate 442 facing the first fixed plate 441, and the guide column and the guide sleeve are slidably connected; a spring is sleeved on the guide column, and one end of the spring abuts against the first fixed plate 441, and the other end of the spring abuts against the guide sleeve.

[0076] Specifically, in this embodiment, the power mechanism 430 moves from the first rivet head 410 toward the second rivet head 420, first compressing the elastic mechanism 440, and when the elastic mechanism 440 can no longer be compressed, then riveting the first through hole 111 and one end of the sleeve 600, and simultaneously riveting the second through hole 121 and the other end of the sleeve 600; after the riveting is completed, the power mechanism 430 moves from the second rivet head 420 toward the first rivet head 410, first releasing the elastic mechanism 440, and simultaneously the elastic mechanism 440 makes the second rivet head 420 withdraw from the second through hole 121, and continues to move to make the first rivet head 410 withdraw from the first through hole 111, thereby completing the bilateral riveting of the first end plate 110 and the second end plate 120.

[0077] In this process, only one power mechanism 430 is set on one side of the first end plate 110, and an elastic mechanism 440 is set on one side of the second end plate 120. After riveting is completed, the elastic mechanism 440 causes the second rivet head 420 to withdraw from the second through hole 121, thereby achieving automatic detachment of the rivet heads at both ends even when only one power component is set. Compared with the setting of setting one power mechanism 430 on both sides, power (cost) is saved.

[0078] Preferably, the inner walls of the first through hole 111 and the second through hole 121 are both provided with a plurality of notches 130, and the first rivet head 410 and the second rivet head 420 are both provided with a plurality of protrusions 401; when the first rivet head 410 / the second rivet head 420 moves toward the first through hole 111 / the second through hole 121, the protrusions 401 abut against the notches 130.

[0079] A notch 130 is provided on the inner wall of the first through hole 111 and the second through hole 121, so that the parts near the first through hole 111 / the second through hole 121 will not be squeezed against each other during the riveting deformation, thereby reducing the effect; at the same time, a protrusion 401 is provided at the first rivet head 410 and the second rivet head 420, and the protrusion 401 abuts against the notch 130. The protrusion 401 divides the parts near the first through hole 111 / the second through hole 121 into a plurality of deformation parts 131. During the deformation, due to the isolation of the protrusion 401, the deformation parts 131 will not interfere with each other; the combination of the protrusion 401 and the notch 130 can also play a guiding role, so that the movement direction of the first rivet head and the second rivet head is more accurate, so as to enhance the riveting effect.

[0080] Preferably, the depth of the notch 130 gradually decreases from the first through hole 111 / the second through hole 121 toward the sleeve 600 to form a first guide bevel 132; the thickness of the protrusion 401 gradually decreases from the first rivet head 410 / the second rivet head 420 toward the sleeve 600 to form a second guide bevel 402; when the first rivet head 410 / the second rivet head 420 moves toward the first through hole 111 / the second through hole 121, the first guide bevel 132 fits with the second guide bevel 402.

[0081] The first guide bevel 132 and the second guide bevel 402 are arranged to have the above-mentioned inclined direction, so that the force between the first guide bevel 132 and the second guide bevel 402 is gradually increased, which is conducive to deformation and then riveting, and can improve the riveting effect. At the same time, it also has a guiding function, which corrects the directional error of the first rivet head 410 / the second rivet head 420 and improves the riveting effect.

[0082] Furthermore, the inner walls of the first through hole 111 and the second through hole 121 are respectively provided with four notches 130 evenly disposed along the circumference thereof, the first rivet head 410 and the second rivet head 420 are respectively provided with four protrusions 401 evenly disposed along the circumference thereof, and the four notches 130 correspond to the four protrusions 401 one by one.

[0083] The notches 130 are evenly arranged so that the size of each deformation portion 131 is consistent, thereby achieving consistency in the amount of deformation, and ultimately achieving the effect of the same riveting strength at each portion.

[0084] Preferably, a deformation portion 131 is provided between any two adjacent notches 130 , and the first rivet head 410 / the second rivet head 420 moves toward the sleeve 600 to drive the deformation portion 131 to bend toward the sleeve 600 .

[0085] Specifically, the portion of the first end plate 110 / the second end plate 120 between two adjacent notches 130 is deformed (i.e., the deformation portion 131), and the deformation portion 131 bends along with the movement of the first rivet head 410 / the second rivet head 420 (or has other forms of deformation, where bending is understood as deformation in a broad sense), so that the deformation portion 131 is connected to the sleeve 600 as a whole to achieve riveting.

[0086] Preferably, the first rivet head 410 and the second rivet head 420 have a guide portion at one end close to the sleeve 600, and the outer diameter of the guide portion gradually decreases from the first rivet head 410 / the second rivet head 420 toward the sleeve 600 to form a guide slope 421, and the minimum outer diameter of the guide portion is smaller than the inner diameter of the first through hole 111 and / or the second through hole 121.

[0087] The setting of the guiding slope 421 can also correct the movement direction error of the first rivet head 410 / the second rivet head 420, so that it moves toward the axial direction of the sleeve 600, thereby achieving consistent force on each deformation part 131 and improving the riveting effect.

[0088] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0089] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0090] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0091] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
