[0002] With the rapid development of modern industrial manufacturing technology, the requirements for precision processing and manufacturing have been raised to an unprecedented level. Rivets, as key industrial connectors, their quality and performance are directly related to the overall stability and service life of the product.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-13The present invention provides a technical solution: an intelligent chamfering device for rivet production, comprising a base 1, a chamfering mechanism is arranged on the base 1, the chamfering mechanism is a prior art, comprising a cutter head driven to rotate by a motor and a pneumatic cylinder body driving the cutter head to move up and down, and also comprising a transfer plate 2 fixedly arranged on the base 1, the end of the transfer plate 2 is connected to an external conveying device for conveying rivets, in this embodiment, the external conveying device is a vibrating conveyor, which can convey the rivet to the transfer plate 2, an adaptive movable disk 3 is movably arranged on the base 1 to drive the rivet to move and complete the chamfering, a moving part 4 is arranged in the adaptive movable disk 3, and the moving part 4 can drive the rivet to extend a fixed distance on the adaptive movable disk 3, a limiting plate 5 is fixedly arranged on the base 1, the inner contour of the limiting plate 5 is an arc shape and fits with the adaptive movable disk 3, and can limit the rivet so that it will not separate from the adaptive movable disk 3, and a positioning component 6 is also arranged on the base 1, which can fix the rivet during chamfering:

[0039] A driving base is provided on the base 1, and the adaptive movable disk 3 is provided above the driving base and is transmission-connected thereto. The driving base can drive the adaptive movable disk 3 to rotate. A plurality of workstations 8 for placing rivets are provided on the adaptive movable disk 3. The driving base includes a motor, which is transmission-connected to the adaptive movable disk 3 through a coupling. Each start-up can drive the adaptive movable disk 3 to rotate, and each workstation 8 is rotated to the bottom of the chamfering mechanism in turn. A plurality of slots 9 are provided on the side wall of the workstation 8, and the movable part 4 is arranged in the slot 9. A placing plate 10 is movably provided at the bottom of the adaptive movable disk 3, and the placing plate 10 is slidingly provided on the adaptive movable disk 3.

[0040] The moving member 4 includes a rotating shaft 41 rotatably arranged in the slot 9, a roller 42 is fixedly arranged on the outer side of the rotating shaft 41, a torsion spring 43 is arranged on the outer side of the rotating shaft 41, and the two ends of the torsion spring 43 are respectively fixedly connected to the roller 42 and the inner wall of the slot 9, a gear 44 is fixedly arranged on the outer side of the rotating shaft 41, a rack 45 meshing with the gear 44 is slidably arranged in the slot 9, and a limit block 46 is arranged at the bottom of the slot 9;

[0041] When the rivet moves into the work station 8, the rivet is restricted in the work station 8 by the cooperation of the adaptive movable disk 3 and the limit plate 5, and the side of the rivet contacts the outer side of the roller 42. When the rivet moves upward, it can drive the roller 42 to rotate, and the roller 42 drives the rotating shaft 41 to rotate. The rotating shaft 41 drives the gear 44 to engage with the rack 45, thereby moving the rack 45. When the rack 45 moves to the limit block 46, the rack 45 cannot move under the action of the limit block 46. At this time, the roller 42 is positioned, and the rivet cannot continue to move under the action of friction.

[0042] A screw rod 47 is rotatably arranged in the slot 9, the top end of the screw rod 47 rotates through the adaptive movable disk 3 and a knob is arranged on the top end, a sleeve 48 is threadedly sleeved on the outer side of the screw rod 47, a limit block 46 is fixedly arranged on the sleeve 48, a fixing block 49 is also arranged on the sleeve 48, and a guide rod 410 is fixedly arranged in the slot 9 and passes through the fixing block 49;

[0043] Rotating the screw rod 47 can drive the sleeve 48 to move, and the sleeve 48 drives the limit block 46 to move. By adjusting the position of the limit block 46, the stroke of the rack 45 can be adjusted, thereby limiting the rolling of the roller 42, so that the rivet drives the roller 42 to roll for a certain distance and then cannot roll, thereby limiting the moving distance of the rivet.

[0044] A plurality of sockets 11 are provided at the bottom of the adaptive movable disk 3, a slide bar 12 is movably provided in the socket 11, a placement plate 10 is fixedly provided at the bottom of the slide bar 12, a connection groove 13 is provided on the outside of the socket 11, the connection groove 13 connects the plurality of sockets 11, a side groove 14 is provided at one end of the connection groove 13, a connection valve 7 is fixedly provided in the side groove 14, a top block 15 capable of conducting the connection valve 7 is provided in the limit plate 5, a pipeline is fixedly connected to a position near the top block 15 on the limit plate 5, the pipeline is connected to a negative pressure pump, the negative pressure pump is a prior art and is not drawn in the figure.

[0045] The connecting valve 7 includes a connecting block 71 fixedly arranged in the side groove 14, a through hole is opened on the connecting block 71, a fixing ring 72 is fixedly arranged in the through hole, a connecting spring 73 is fixedly connected to one end of the fixing ring 72, a baffle 74 is fixedly arranged at the end of the connecting spring 73, a movable plug 75 is fixedly arranged on the baffle 74, the movable plug 75 is movably arranged in the fixing ring 72, and a cross bar 76 is fixedly connected to the end of the movable plug 75. When the movable plug 75 moves out of the fixing ring 72, the connecting block 71 is turned on, and the movable plug 75 can be turned on. So that the side groove 14 and the connecting groove 13 are connected to the external negative pressure pump, the negative pressure pump will reduce the air pressure in the socket 11, so the slide bar 12 will drive the placement plate 10 to move upward, and then drive the rivet to move upward, and the rivet will drive the roller 42 to rotate when it moves. It is worth noting that the power of the negative pressure pump can be set according to the friction between the roller 42 and the rivet, so that the force driven by the air pressure to move the slide bar 12 cannot overcome the sliding friction between the roller 42 and the rivet, but can drive the roller 42 to rotate when the rivet moves.

[0046] A cavity is provided in the limiting plate 5, and a top block 15 is slidably provided in the cavity. The end of the top block 15 close to the connecting block 71 is V-shaped and a supporting spring 16 is provided at the other end. The two ends of the supporting spring 16 are respectively fixedly connected to the top block 15 and the limiting plate 5. A through hole is provided in the top block 15, and the through hole is connected to the cavity and the cavity is connected to the pipeline. When the top block 15 is connected to the connecting valve 7, under the action of the supporting spring 16, the top block 15 drives the cross bar 76 to move, and the movement of the cross bar 76 drives the moving plug 75 to disengage from the fixing ring 72, thereby connecting the jack 11 to the negative pressure pump.

[0047] A side plate 17 is also provided on the outside of the adaptive movable disk 3, and a top block 18 is movably provided inside the side plate 17. The top block 18 has the same structure as the top block 15 and a supporting spring 19 is provided at the bottom. Similarly, when the connecting valve 7 is rotated to dock with the top block 18, the top block 18 squeezes the cross bar 76 to move it. At this time, the socket 11 is connected to the outside world, so that the normal air pressure in the socket 11 is restored, and the placement plate 10 is reset.

[0048] The positioning assembly 6 includes a cylinder 61 fixedly mounted on the base 1, and a positioning block 62 is fixedly mounted on the output end of the cylinder 61. The end of the positioning block 62 is arc-shaped. When the cylinder 61 is started, it drives the positioning block 62 to move, so that the rivet is fixedly stuck in the work station 8, and then the chamfering operation is performed.

[0049] In summary, when chamfering, the rivet will first be transported to the station 8 docked with the transfer plate 2, and then the adaptive movable disk 3 rotates to drive the station 8 to move. At this time, the connecting valve 7 is docked with the top block 15, thereby reducing the air pressure in the socket 11. The placement plate 10 and the slide bar 12 drive the rivet to move upward under the action of the air pressure. When the rivet moves, it drives the roller 42 to rotate. When the roller 42 cannot rotate, the position of the rivet will not change. Since the rolling stroke of the roller 42 is constant, no matter how long the rivet is, the rolling stroke of the roller 42 is counted from the time when the top of the rivet starts to contact the roller 42. Therefore, the length of the rivet extension is consistent, so that the cutting amount is consistent each time during cutting. After the chamfering is completed, the adaptive movable disk 3 rotates again. At this time, the work station 8 moves to the top block 18. The top block 18 squeezes the cross bar 76 to make the jack 11 conductive with the outside world. At this time, the placement plate 10 is reset, and due to the action of the torsion spring 43, the roller 42 will instantly reset after the restriction is released. The rotation of the roller 42 will immediately throw the rivet out of the work station 8 to realize the unloading of the rivet, and then the adaptive movable disk 3 continues to rotate to the transfer plate 2, and so on. The above operations can be repeated to perform the chamfering operation of the rivet.

[0050] Embodiment 2:

[0051] On the basis of the first embodiment, a rubber layer is provided on the outer side of the roller 42 in the second embodiment. When the rivet is fixed, the buffering deformation of the rubber layer can not only avoid damage to the rivet surface, but also better fix the rivet and increase the friction between the roller 42 and the rivet, thereby driving the rivet to move more stably.
