Description

Technical Field

[0001] The invention relates to the technical field of metal riveting, and in particular to a sleeve clamping and conveying mechanism and device for riveted parts. 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 performed manually by personnel, resulting in inaccurate positioning and low efficiency. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a sleeve clamping and conveying mechanism and device for riveted parts.

[0006] The technical solution adopted by the present invention to solve the technical problem is a sleeve clamping and conveying mechanism for riveted parts, comprising:

[0007] The clamping assembly comprises: a first clamping member, which is arranged on one side of the sleeve and has a first clamping portion; a second clamping member, which is arranged on the other side of the sleeve and has a second clamping portion, and the second clamping member can move along a first direction to reduce or increase the distance between the first clamping portion and the second clamping portion to clamp or release the sleeve;

[0008] The conveying assembly is connected to the clamping assembly, and the conveying assembly can drive the clamping assembly to move along the second direction to convey the sleeve into the riveting piece.

[0009] Preferably, the first direction is perpendicular to the second direction.

[0010] Preferably, the clamping assembly also includes: a sliding plate connected to the conveying assembly; a first guide rail, which is arranged on the sliding plate along a first direction, the first clamping member is fixed on the sliding plate, the second clamping member is connected to the first guide rail, and the second clamping member can slide relative to the guide rail along the first direction; a first driving cylinder, used to drive the second clamping member to slide relative to the first guide rail.

[0011] Preferably, the conveying assembly includes: a fixed plate, on which a second guide rail is provided, and the second guide rail is arranged along a second direction, and the sliding plate is slidably arranged on the second guide rail; and a second driving cylinder, used to drive the sliding plate to slide relative to the second guide rail.

[0012] Preferably, the first clamping portion is arranged in an arc shape, and the first clamping portion is in contact with the side wall of the sleeve.

[0013] Preferably, the second clamping portion is provided with an elastic sheet, the elastic sheet is arranged in an arc shape, and the elastic sheet is in contact with the side wall of the sleeve.

[0014] Preferably, it also includes a positioning assembly, which includes a positioning column arranged between the first clamping part and the second clamping part; a driving member, used to drive the positioning column to move along a third direction to extend into or out of the sleeve; any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0015] Preferably, the positioning column is cylindrical, and the side wall of the positioning column is in contact with the inner wall of the sleeve.

[0016] Preferably, a guide portion is provided at one end of the positioning column, and a thickness of the guide portion gradually decreases from the center to the end of the positioning column to form a guide surface.

[0017] Preferably, the present invention further discloses a sleeve clamping and conveying device for a riveted part, comprising a sleeve clamping and conveying mechanism for a riveted part, wherein the riveted part comprises a first pipe and a second pipe arranged along a first direction, wherein the first pipe has at least two riveted parts arranged along a second direction, and the second pipe has at least one riveted part;

[0018] Two clamping assemblies are arranged along the first direction, and one of the clamping assemblies is provided with two first clamping parts and two second clamping parts, and the other clamping assembly is provided with at least one first clamping part and at least one second clamping part.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0040] 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.

[0041] Please refer to Figure 1-Figure 7 The present invention discloses a sleeve clamping and conveying mechanism for riveted parts, comprising:

[0042] The clamping assembly 200 includes: a first clamping member 210, which is disposed on one side of the sleeve 600 and has a first clamping portion 213; a second clamping member 220, which is disposed 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;

[0043] The conveying assembly 300 is connected to the clamping assembly 200 , and the conveying assembly 300 can drive the clamping assembly 200 to move along the second direction to convey the sleeve 600 into the riveting component 100 .

[0044] 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.

[0045] 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.

[0046] Preferably, the first direction is perpendicular to the second direction.

[0047] 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.

[0048] 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.

[0049] Specifically, the second clamping member 220 slides relative to the first guide rail 230 to achieve movement of the second clamping member along the first direction, thereby changing the distance between the second clamping member 220 and the first clamping member 210 , and finally achieving clamping and loosening of the sleeve 600 .

[0050] 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.

[0051] Preferably, 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.

[0052] 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 .

[0053] 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.

[0054] 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.

[0055] Preferably, the first clamping portion 213 is arranged in an arc shape, and the first clamping portion 213 is in contact with the side wall of the sleeve 600 .

[0056] 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 .

[0057] Preferably, the second clamping portion 223 is provided with an elastic sheet 224 , the elastic sheet 224 is provided in an arc shape, and the elastic sheet 224 is in contact with the side wall of the sleeve 600 .

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Preferably, it also includes a positioning assembly 500, which 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.

[0062] 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.

[0063] 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.

[0064] 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 .

[0065] The side wall of the positioning column 510 is arranged to fit with the inner wall of the sleeve 600 , so that the positioning of the sleeve 600 can be more accurate.

[0066] Preferably, a guide portion is provided at one end of the positioning column 510 , and a thickness of the guide portion gradually decreases from the center to the end of the positioning column 510 to form a guide surface 511 .

[0067] 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.

[0068] Preferably, the present invention further discloses a sleeve clamping and conveying device for riveted parts, comprising a sleeve clamping and conveying mechanism for riveted parts, wherein the riveted part 100 comprises a first pipe 110 and a second pipe 120 arranged along a first direction, wherein the first pipe 110 has at least two riveted parts 130 arranged along a second direction, and the second pipe 120 has at least one riveted part 130;

[0069] Two clamping assemblies 200 are arranged along the first direction, and one of the clamping assemblies 200 is provided with two first clamping portions 213 and two second clamping portions 223 , and the other clamping assembly 200 is provided with at least one first clamping portion 213 and at least one second clamping portion 213 .

[0070] Specifically, the conveying device is mainly used for riveting the tubular component of the front cabin of the automobile and the sleeve 600. The tubular component has a first pipe 110 and a second pipe 120. Therefore, two clamping assemblies 200 are provided, and the two clamping assemblies 200 share one conveying assembly 300.

[0071] Furthermore, in the device, at least three laser positioning members 400 (each laser positioning member 400 corresponds to the position of a sleeve 600) are provided, and laser irradiation is used to determine whether the sleeve 600 is clamped between the first clamping portion 213 and the second clamping portion 223, so as to proceed to the next step according to the determination result, so that all steps before and after riveting can be controlled by the control system, thereby reducing personnel costs and improving efficiency.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.
