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.

[0027] Example:

[0028] Please refer to the attached Figure 1 -Attached Figure 6The embodiment of the present invention provides a riveting machine for continuous riveting of parts, including a reinforcing plate 15, the left and right sides of the reinforcing plate 15 are fixedly connected to a bottom plate 1, the top outer sides of the two bottom plates 1 are fixedly connected to side outer plates 2, the top of the reinforcing plate 15 is fixedly connected to a support frame 3, the top of the inner top of the support frame 3 is fixedly connected to a top plate 28, a conveying mechanism is arranged between the two side outer plates 2, a connecting rod 10 is arranged between the two side outer plates 2, a second connecting member 12 is fixedly connected to the front side of the connecting rod 10, and a second connecting member 12 is fixedly connected to the front side of the connecting rod 10. The second linking member 12 is fixedly connected to a limiting member 14 on the left side, and the limiting member 14 is slidably connected to the surface of the first linking member 8. The top of the right bottom plate 1 is fixedly connected to a first motor 13, and the output end of the first motor 13 is fixedly connected to a fixed disk 9, which is in contact with the second linking member 12 and the first linking member 8. Two cylinders 29 are fixedly connected to the rear position of the front side of the bottom of the side outer plate 2, and the output ends of the two cylinders 29 are fixedly connected to a second push plate 30, and the bottom of the inner wall of the support frame 3 is fixedly connected to a conveying bar 18.

[0029] The first motor 13 drives the fixed plate 9 to rotate, and the cylinder at the front end of the fixed plate 9 squeezes the second linking piece 12 to the right, causing the linking rod 10 to shift to the right, so that the first push block 11 on the left also moves to the right, so that the first push block 11 on the left pushes the parts on the left conveyor belt 26 to the extrusion block 23 on the left. Then, as the fixed plate 9 rotates, the cylinder at the front end of the fixed plate 9 contacts the first linking piece 8, lifts the first linking piece 8 upward, and the linking rod 10 is pushed to the left. The first push block 11 on the right moves to the left, pushing the parts on the right conveyor belt 26 to the left, so that the parts are pushed to the extrusion block 23 on the right. After the riveting is completed, the corresponding cylinder 29 is started, and the output end of the cylinder 29 drives the second push plate 30 to pop out forward, thereby popping out the processed parts on the corresponding extrusion block 23.

[0030] The conveying mechanism includes two side inner plates 24, and conveyor belts 26 are arranged on opposite sides of the two side inner plates 24. Extrusion blocks 23 are fixedly connected to the front sides of the two side inner plates 24. A second motor 25 is arranged between the two side inner plates 24, and the output ends of the second motor 25 are fixedly connected to the conveyor belts 26.

[0031] The second motor 25 is a double-headed motor. The second motor 25 is used to drive the driving rollers in the two conveyor belts 26. The second motor 25 drives the driving rollers, and the driving rollers drive the transmission belts to work, so that the two conveyor belts 26 can work simultaneously and synchronously, thereby ensuring consistent efficiency in conveying parts.

[0032] The two extrusion blocks 23 are both fixedly connected to the reinforcing plate 15 , and the second motor 25 is fixedly connected to the reinforcing plate 15 .

[0033] When the hydraulic cylinder 31 is pressed down, a huge pressure is generated to squeeze and deform the rivet, so that the extrusion block 23 is subjected to a huge pressure. When the extrusion block 23 is fixed together with the reinforcing plate 15, part of the pressure borne by the extrusion block 23 can be transferred and dispersed to the entire device.

[0034] The first push blocks 11 are fixedly connected to both ends of the linkage rod 10 , the side outer plate 2 and the linkage rod 10 are slidably connected, the first push blocks 11 are slidably connected to the side outer plate 2 , and the linkage rod 10 and the reinforcing plate 15 are slidably connected.

[0035] The first push block 11 is used to push the unprocessed parts onto the corresponding extrusion block 23, and an opening having the same size as the linkage rod 10 is opened on the reinforcement plate 15, so that the linkage rod 10 can only slide left and right but cannot move forward and backward.

[0036] A conveying groove 19 is provided at the center of the bottom of the conveying bar 18 . The left and right sides of the front end of the conveying bar 18 are fixedly connected with diverter blocks 17 . The bottom of the diverter blocks 17 are provided with through grooves 22 .

[0037] There are two diverter blocks 17, corresponding to two extrusion blocks 23 respectively. The front rivet is squeezed and pushed forward by the rear rivet. When the rivet moves to the through slot 22, as the output end of the hydraulic cylinder 31 presses down, the delivery end of the hydraulic cylinder 31 also squeezes the rivet out of the diverter block 17 along the through slot 22.

[0038] The bottom of the top plate 28 is fixedly connected to a steering gear 21 , an output end of the steering gear 21 is fixedly connected to a connecting shaft 16 , the connecting shaft 16 penetrates and is fixedly connected to a dial plate 20 , and the connecting shaft 16 penetrates and extends to the bottom side of the dial plate 20 .

[0039] The connecting shaft 16 is driven to rotate by the steering gear 21, so that the dial plate 20 on the connecting shaft 16 swings. As the dial plate 20 swings, the rivets in the conveying trough 19 are sequentially pushed into the two diverter blocks 17, and the cycle is repeated. There will not be a situation where rivets appear in the two diverter blocks 17 at the same time and no rivets appear at the same time.

[0040] Sliding holes 4 are provided at the lower positions of the tops of the front sides of the two side outer plates 2 , and the sliding holes 4 are slidably connected to the first push blocks 11 .

[0041] The slide hole 4 is provided to allow enough space for the first push block 11 to pass through, so that the first push block 11 can push the parts from the conveyor belt 26 to the extrusion block 23 .

[0042] Connecting plates 5 are fixedly connected between the two side outer plates 2 at both the front and rear sides, and the connecting plates 5 are fixedly connected to the bottom plate 1 .

[0043] Two placement holes 27 are provided on the front side of the top of the top plate 28 . A plurality of support rods 6 are fixedly connected to the top of the top plate 28 . A fixing piece 7 is provided between the tops of four adjacent support rods 6 .

[0044] The support rod 6 and the top plate 28 are welded together, and the support rod 6 passes through the fixing member 7 and is tightened with a nut to fix the fixing member 7.

[0045] A hydraulic cylinder 31 is provided on the inner diameter of the placement hole 27 , the top of the hydraulic cylinder 31 is fixedly connected to the fixing member 7 , and the hydraulic cylinder 31 is fixedly connected to the placement hole 27 .

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
