Description

Technical Field

[0001] The utility model relates to the technical field of stud riveting, in particular to a stud feeding device for riveting. Background Art

[0002] In order to achieve the connection between the workpiece and other parts, studs are usually riveted on the workpiece. The existing riveting machine usually has an upper die structure that can press down (for riveting and pressing down), a lower die structure located below the upper die structure (for positioning the workpiece to be processed), and a feeding structure for separating and transmitting the studs one by one. Taking the top-down riveting as an example, during the specific operation, the workpiece is first placed on the lower die structure, and then the stud is squared (the stud head is at the top) on the pre-set feeding station with the help of the feeding structure, so that it can face the top of the riveting through hole punched out in advance in the workpiece, and finally the upper die structure is started to press down to achieve the riveting of the stud and the workpiece. In the existing feeding structure, the studs are arranged one by one by a vibrator, but in practice, a sufficient amount of studs must be ensured in the vibrator, so that the studs close to the arrangement channel area can be moved to the arrangement channel through the vibration, and it takes a long time for the studs far away from the arrangement channel area to move to the arrangement channel. In addition, during the arrangement process, the studs are prone to turning over and getting stuck in the arrangement channel. It can be seen that the existing feeding structure is prone to affect the quality and efficiency of stud feeding. Utility Model Content

[0046] In order to enable those skilled in the art to better understand the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, not all of them. Based on the embodiments recorded in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figures 1 to 12 As shown, a stud feeding device for riveting includes a feeding support frame 1, and a feeding seat 2 is provided on the feeding support frame 1;

[0049] The left end of the loading seat 2 is provided with a receiving groove 3, and the right end of the loading seat 2 is provided with a roller groove 4 connected with the receiving groove 3. A roller 6 is rotatably connected in the roller groove 4, and a plurality of scoops 7 are arranged along the circumferential direction of the roller 6 on the inner wall surface thereof;

[0050] A central plate 8 is also provided in the loading seat 2, spanning the receiving groove 3 and the roller groove 4. The central plate 8 is inclined, and the height gradually decreases from the roller groove 4 to the receiving groove 3.

[0051] The left end of the central plate 8 is provided with a central groove 9 arranged in a front-to-back direction, and the loading seat 2 is also provided with an arrangement track 11 connected with the central groove 9;

[0052] The loading seat 2 is also provided with a vibrator 10 for acting on the central plate 8 and the arrangement track 11;

[0053] The feeding support frame 1 is provided with a rotation driving assembly for driving the roller 6 to rotate. When the roller 6 rotates so that any one of the plurality of digging spoons 7 is located at the top, the digging spoon 7 is directly above the central plate 8.

[0054] Preferably, the digging spoon 7 is arc-shaped;

[0055] The opening direction of the scoop 7 is arranged along the rotation direction of the drum 6 .

[0056] Preferably, the arranging track 11 has an arranging groove, which includes an arranging stud groove section 14 and an arranging stud head groove section 13 connected to the top end of the arranging stud groove section 14 and having a width greater than that of the arranging stud groove section 14 .

[0057] When this embodiment is used, a sufficient amount of studs are poured from the receiving groove 3 into the loading seat 2, and the rotating drive assembly is started to rotate the drum 6. Taking any of the digging spoons 7 as an example, during the movement from the high position to the low position, the digging spoon 7 will shovel the studs at the bottom into it, and during the movement from the low position to the high position, the digging spoon 7 will pour the studs inside it onto the central plate 8. Due to the inclined setting of the central plate 8 and the effect of the vibrator 10, the studs will move into the central groove 9, and then through the effect of the vibrator 10, the studs will move from the central groove 9 to the arrangement track 11. In this way, the studs can be arranged one by one efficiently to prepare for the subsequent feeding operation.

[0058] When the studs are arranged on the arrangement track 11, the stud sections of the studs are placed in the arrangement stud slot sections 14, and the stud head sections of the studs are located in the arrangement stud head slot sections 13. In this way, the studs can be kept in a positive state (the stud head sections are at the top) and prevented from accidentally flipping when the studs move in the arrangement track 11.

[0059] In order to facilitate the stud in the receiving groove 3 to approach the inner ring bottom surface of the roller 6, the groove bottom of the receiving groove 3 can be set in an arc surface, and the groove depth of the receiving groove 3 gradually deepens in the direction close to the roller 6, such as Figure 1 The orientation of this embodiment is in the transmission direction of the arrangement track 11 as the front. In order to facilitate the stud to vibrate from the central groove 9 to the arrangement track 11, the bottom of the central groove 9 can be inclined, and the groove depth gradually deepens from the back to the front. Figure 7 The vibrator 10 can be arranged at the bottom end of the central plate 8 and at the rear end of the arrangement track 11 .

[0060] like Figure 1 As shown, the rotation drive assembly includes a roller driving device 38, a roller driven transmission wheel 39 rotatably arranged on the feeding support frame 1, a roller driving gear 40 coaxially and linked to the roller driven transmission wheel 39, and a roller driven gear 41 arranged on the outer ring surface of the roller 6 and meshing with the roller driving gear 40; the rotation drive assembly also includes a roller driving transmission wheel 42 connected to the roller driving device 38 and a roller driving belt 43 sleeved on the roller driving transmission wheel 42 and the roller driven transmission wheel 39. When used, the roller driving device 38 is started to drive the roller driving transmission wheel 42 to rotate, and under the action of the roller transmission belt 43, the roller driving gear 40 can be driven to rotate, and the roller 6 can be driven to rotate through the meshing of the roller driving gear 40 and the roller driven gear 41. The roller driving device 38 can be a motor.

[0061] Preferably, the loading seat 2 is rotatably connected to a rotating shaft 12, and the rotating shaft 12 is provided with a sweeping plate 52 located above the arrangement track 11;

[0062] The loading seat 2 is also provided with a swing driving component for driving the rotating shaft 12 to swing.

[0063] In this embodiment, when the studs on the central plate 8 are in excess and the studs on the arrangement track 11 are filled up, some of the studs will return to the receiving groove 3, while some of the studs will overlap on the top of the arrangement track 11. When normal feeding is carried out, there will be empty spaces on the arrangement track 11, and the overlapping studs will easily get stuck or flip over on the arrangement track 11. By setting the swing drive assembly, the sweeping plate 52 can be driven to make a small swinging motion, so that the overlapping studs can be swept away in time.

[0064] like Figure 7 As shown, the swing drive assembly includes a swing drive device 44, a swing driving driving wheel 45 sleeved on the output end of the swing drive device 44, a swing driven driving wheel 46 sleeved on the rotating shaft 12, and a swing driving belt 47 sleeved on the swing driving driving wheel 45 and the swing driven driving wheel 46. When the swing drive device 44 is started to drive the swing driving driving wheel 45 to rotate forward or reverse, the rotating shaft 12 can be driven to swing under the transmission action of the swing driving belt 47. The swing drive device 44 can be a motor.

[0065] like Figure 3 As shown, in order to facilitate the redundant studs to fall back from the arrangement track 11 into the receiving groove 3, inclined surfaces are provided on both sides of the arrangement track 11.

[0066] Preferably, the central plate 8 has a central channel 29 , and the central plate 8 is provided with central ribs 19 on both sides of the central channel 29 .

[0067] In this embodiment, the central retaining edge 19 can prevent the studs that fall into the central plate 8 from accidentally falling out of the central plate 8 due to vibration.

[0068] Preferably, the drum 6 is provided with a limiting protrusion 53 , and the inner wall of the drum groove 4 is provided with a limiting ring groove 20 that cooperates with the limiting protrusion 36 .

[0069] In this embodiment, the rotation stability of the drum 6 can be improved by the cooperation between the limiting protruding ring 53 and the limiting ring groove 20 .

[0070] Preferably, the feeding support frame 1 is further provided with a feeding channel 15 connected with the arrangement track 11, and the feeding channel 15 has a feeding trough, and the feeding trough includes a feeding stud slot section 16, a feeding stud head slot section 17 and a feeding anti-slip slot section 18 which are arranged in sequence from bottom to top;

[0071] A feeding notch 31 communicating with the feeding trough is formed at the front end of the feeding channel 15, and a clearance opening 32 communicating with both the feeding trough and the feeding notch is formed at the bottom end of the feeding channel 15;

[0072] The end of the feeding channel 15 is also provided with an elastic blocking component for blocking or connecting the feeding notch 31 and the feeding trough.

[0073] In this embodiment, the feeding channel 15 is used to transfer the stud to the riveted part of the workpiece to be riveted. When in use, when the stud is transferred on the feeding channel 15, the stud section of the stud is placed in the feeding stud slot section 16, and the stud head section of the stud is located in the feeding stud head slot section 17. The width of the feeding anti-slip slot section 18 is smaller than the outer diameter of the stud head, so that the stud can be prevented from accidentally escaping from the feeding channel 15, and at the same time, it can also prevent the stud from accidentally flipping when moving in the feeding channel 15.

[0074] The elastic blocking assembly may include two symmetrically disposed and spaced apart elastic blocking sheets 5 , so that during the idle feeding period, the elastic blocking sheets 5 can prevent the stud from escaping from the feeding channel 15 .

[0075] Preferably, it also includes a feeding positioning structure 21, on which a plurality of positioning pins 28 capable of penetrating the studs are arranged;

[0076] A plurality of feeding support frames 1 are arranged around the feeding positioning structure 21;

[0077] It also includes a positioning up and down driving device 23 for driving the feeding positioning structure 21 to move up and down, and a feeding front and back driving device 25 for driving the feeding support frame 1 to move forward and backward.

[0078] In this embodiment, according to the riveting requirements, a corresponding number of feeding support frames 1 may be arranged around the feeding positioning structure 21, and each feeding support frame 1 may provide one stud each.

[0079] During application, a riveting through hole that can be penetrated and matched with the positioning pin 28 is provided on the workpiece to be riveted. The workpiece is placed on the feeding positioning structure 21, and each positioning pin 28 is passed through the corresponding riveting through hole. The feeding positioning structure 21 is moved downward by the positioning up and down drive device 23. At the same time, the feeding support frame 1 is moved forward by the feeding front and rear drive device 25, so that the stud at the front end of the feeding channel 15 is located directly above the positioning pin 28. The feeding positioning structure 21 is then reset and moved upward by the positioning up and down drive device 23, so that the positioning pin can pass through the stud through the clearance opening 32. The feeding support frame 1 is reset and moved back by the feeding front and rear drive device 25. At this time, the stud will pass through the elastic blocking sheet 5 and the feeding notch 31 and stay on the positioning pin. In this process, the positioning pin 28 also passes through the clearance opening 32 and the feeding notch 31. In this way, the fixed-point feeding of the stud is completed.

[0080] Preferably, it also includes a transfer adsorption plate 22;

[0081] The transfer adsorption plate 22 is provided with a plurality of suction cups 27 and a plurality of positioning pressing cylinders 30 which are inserted and matched with the positioning pins 28;

[0083] In this embodiment, when the stud remains on the positioning pin, the transfer adsorption plate 22 can be moved downward by setting the transfer up and down drive device 24, so that the positioning pressing cylinder 30 will be set on the positioning pin 28 and gradually press the stud 36 to the riveting through hole. Then, through the adsorption effect of the suction cup 27 and the action of the transfer left and right drive device 26, the workpiece can be transferred to the stamping operation table to complete the riveting work of the stud. When used, the suction cup 27 can be connected to a vacuum generator, and the vacuum generator is started so that negative pressure can be generated in the suction cup 27.

[0084] The cooperation between the left and right transfer drive devices 26 and the suction cup 27 can not only complete the unloading of the workpiece, but also complete the loading of the workpiece.

[0085] The feeding front and rear drive device 25 and the transfer left and right drive device 26 can both be made of slide modules, cylinders, etc.; the positioning up and down drive device 23 and the transfer up and down drive device 24 can both be made of cylinders.

[0086] Preferably, the elastic blocking assembly includes two clamping pieces 33 arranged opposite to each other, the middle part of the clamping piece 33 is hinged on the feeding channel 15, the rear end of the clamping piece 33 is connected to the feeding channel 15 through a clamping elastic member 34, and the front end of the clamping piece 33 has a blocking section 35;

[0087] The clamping elastic member 34 acts on the clamping piece 33 , so that the blocking section 35 passes through the inner wall of the feeding channel 15 and is located in the feeding notch 31 .

[0088] In this embodiment, a mounting cavity 37 connected to the feeding notch 31 is provided in the feeding channel 15 to mount the clamping piece 33. In use, when the positioning pin 28 passes through the stud 36 from bottom to top and the feeding support frame 1 moves backward, the stud can act on the two clamping pieces 33, so that: the two clamping pieces 33 can compress the supporting effect of the clamping elastic member 34 to rotate, and the blocking section 35 moves into the mounting cavity 37, so that the stud can pass through the feeding notch 31. After the stud passes, the blocking section 35 will be re-positioned in the feeding notch 31 under the action of the clamping elastic member 34 to prevent the next stud from accidentally leaving the feeding channel 15.

[0089] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific embodiments of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, other embodiments derived without departing from the technical solution of the present invention should be included in the protection scope of the present invention.
