[0033] Example:

[0034] Please refer to Figure 1-Figure 6 The present embodiment is a fully automatic riveting machine 100 for connecting rod and steel ball spring, which includes a connecting rod transfer channel 1, a connecting rod angle correction unit 2 arranged along the connecting rod transfer channel 1, a spring feeding unit 3, a steel ball feeding unit 4, a material distribution and dislocation unit 5 for connecting the spring feeding unit 3 and the steel ball feeding unit 4, an insertion mechanism 6 for pushing the steel balls and springs in the material distribution and dislocation unit 5 into the connecting rod receiving hole, a riveting unit 7 for riveting the steel balls in the connecting rod receiving hole, and a material receiving channel 17 arranged at the end of the connecting rod transfer channel 1.

[0035] The connecting rod transfer channel 1 includes a first chute channel 11 located at the bottom and a second chute channel 12 located at the top. The first chute channel 11 and the second chute channel 12 include an inclined portion located at the front section and a horizontal portion connected to the inclined portion. The chute openings at the ends of the first chute channel 11 and the second chute channel 12 are larger than the maximum diameter of the connecting rod, so that it can fall downward.

[0036] The second chute channel 12 is fixed on a first movable plate 14 that can move up and down. The first chute channel 11 is fixedly arranged on a fixed seat, and the height difference between the surface of the second chute channel 12 and the first chute channel 11 can be adjusted by moving the first movable plate 14 up and down, so that the receiving hole at the bottom of the product mounted in the second chute channel 12 is always maintained at a set height, ensuring that the position of the assembly height is fixed, so that it can be applied to the assembly of various connecting rods of different specifications, and improve the versatility of the equipment.

[0037] This embodiment further includes a first driving member 15 for driving the first movable plate 14 to move up and down.

[0038] A positioning and feeding mechanism 9 is also fixedly provided on the first movable plate 14 , and the positioning and feeding mechanism 9 is used to separate the connecting rods one by one and keep the positions stable at each operating station.

[0039] The positioning feeding mechanism 9 includes a first cylinder 91, a second movable plate 92 driven by the first cylinder 91 to move along the connecting rod transfer flow channel 1, a second cylinder 93 fixed on the second movable plate 92, a third movable plate 94 driven by the second cylinder 93 to move perpendicularly to the connecting rod transfer flow channel 1, and a first positioning clamping plate 95 fixed on the third movable plate 94. A plurality of positioning receiving grooves 951 are arranged on the first positioning clamping plate 95 along the connecting rod transfer flow channel 1. The first positioning card plate 95 moves forward and extends into the connecting rod transfer channel 1, isolating each connecting rod into one by one, and confining them in the positioning storage groove 951. The positioning storage groove 951 corresponds to each operating station, such as the connecting rod angle correction station, the spring pressing station, the steel ball pressing station, and the steel ball riveting station; it ensures that the position of the connecting rod is fixed when various operations are performed on the connecting rod, thereby ensuring the accuracy of assembly; after the connecting rod is operated at one station, the first positioning card plate 95 is moved left and right to transport the connecting rod to the next station for operation.

[0040] Since most of the main parts of the connecting rod are rod-shaped structures, it is impossible to stop the rotation by positioning the receiving groove 951 when limiting its rotation. In order to prevent the connecting rod angle from rotating during the subsequent assembly process after the connecting rod angle is corrected, resulting in assembly failure, the present embodiment is provided with an upper push mechanism 10 below the connecting rod transfer flow channel 1, and a limit baffle 13 is provided on the horizontal part of the second chute flow channel 12 to limit the upward lifting height of the product in the second chute flow channel 12. The upper push mechanism 10 cooperates with the limit baffle 13 to support the upper and lower ends of the connecting rod to prevent it from rotating, and can also ensure that the bottom of the connecting rod is kept at a uniform height position during each operation, thereby ensuring the position height of the receiving hole and improving the assembly accuracy.

[0041] The lifting mechanism 10 includes a third cylinder 101 and a push rod 102 driven by the third cylinder 101 to move up and down. There are multiple push rods 102 in the lifting mechanism 10, which correspond to the spring pressing station, the steel ball pressing station, and the riveting station. The lifting mechanism 10 can be configured so that one cylinder drives multiple push rods 102 to move simultaneously, or it can be configured as multiple independent driving units, with one cylinder driving one push rod.

[0042] The connecting rod angle correction unit 2 includes a fourth cylinder 21 fixed on the first movable plate 14, a fourth movable plate 22 driven by the fourth cylinder 21 to move up and down, a second driving member 23 fixed on the fourth movable plate 22, and a correction rod 24 driven by the second driving member 23 to rotate. The correction rod 24 is contoured to the groove at the upper end of the connecting rod and the correction rod 24 is inserted into the groove to realize rotation transmission, thereby realizing the adjustment of the connecting rod angle, so that the opening of the storage hole at the rear of the connecting rod faces outward, which is convenient for the subsequent assembly.

[0043] A stopper mechanism 16 is provided on the first movable plate 14 or the second chute flow channel 12 corresponding to the position of the connecting rod angle correction unit 2 to isolate an independent connecting rod. The stopper mechanism 16 includes a front stopper unit 161 and a rear stopper unit 162, and the distance between the front stopper unit 161 and the rear stopper unit 162 is greater than the diameter of one connecting rod head and less than the diameter of two connecting rod heads. The front stopper unit 161 and the rear stopper unit 162 both include a fifth cylinder 163 and a stopper block 164 driven by the fifth cylinder 163 to extend into the connecting rod transfer flow channel 1.

[0044] In order to further ensure the accuracy of the connecting rod position, a positioning mechanism 8 cooperating with the positioning feeding mechanism 9 is provided below the connecting rod transfer flow channel 1. The positioning mechanism 8 includes a fifth cylinder (not shown in the figure) and a second positioning card plate 81 driven by the fifth cylinder to move perpendicularly to the connecting rod transfer flow channel 1. The second positioning card plate 81 is also provided with a plurality of card slots corresponding to the positioning receiving slots 951 in the first positioning card plate 95.

[0045] The spring feeding unit 3 includes a vibrating plate. The steel ball feeding unit 4 includes a steel ball storage box 41 located at a high position, and a material guide channel (not shown in the figure) docked with the steel ball storage box 41 and leading into the material distribution and dislocation unit 5.

[0046] The material distribution and dislocation unit 5 includes a fixed block 51, a material distribution block 52 that moves in the fixed block 51 along the direction of the connecting rod transfer flow channel 1, the fixed block 51 includes two baffles 511 that are parallel to each other and vertically distributed, and a slide groove 512 formed by the two baffles 511. The two baffles 511 are provided with a first introduction hole 513 and a second introduction hole 514 that are corresponding in position and penetrate from front to back, and the baffle 511 near the output end of the spring feeding unit 3 is provided with a receiving groove 515 that docks with the spring feeding unit 3. The material distribution block 52 is provided with a first material distribution groove 521 that switches back and forth between the docking position of the receiving groove 515 and the docking position of the first introduction hole 513 by moving left and right, and a second material distribution groove 522 that switches back and forth between the docking position of the output port of the steel ball feeding unit 4 and the docking position of the second introduction hole 514 by moving left and right. The ejector rod 102 in the upper ejection mechanism 10 passes through the fixed block 51, which guides the ejector rod 102. The dividing block 52 slides in the sliding groove 512 .

[0047] The ejection mechanism 6 includes a sixth cylinder 61, a driving plate 62 driven by the sixth cylinder 61 to move forward and backward, a support seat 63 fixedly connected to the driving plate 62, and a first ejection rod 64 and a second ejection rod 65 fixed to the support seat 63 and respectively arranged corresponding to the first introduction hole 513 and the second introduction hole 514. The first ejection rod 64 and the second ejection rod 65 are inserted into the first introduction hole 513 and the second introduction hole 514 to eject the spring and the steel ball into the connecting rod receiving hole.

[0048] The driving plate 62 is provided with a guide slot 621, and the material distribution block 52 is provided with a transmission rod 523 passing through the guide slot 621. Under the guidance of the guide slot 621, the material distribution block 52 realizes the left and right movement of the material distribution block 52 through the forward and backward movement of the driving plate 62.

[0049] The riveting unit 7 includes a sixth cylinder 71, a lever arm 72 hinged at one end to the movable end of the sixth cylinder 71, a connecting rod 73 hinged at the other end of the lever arm 72, a riveting rod 74 hinged at the other end of the connecting rod 73, and a riveting head 75 fixed at the end of the riveting rod 74. The lever arm 72 is rotatably mounted on a fixed bracket 77 through a pin 76, and the pin 76 is close to one end of the connecting rod 73, so that the force arm of the driving end of the sixth cylinder 71 is much larger than the force arm of the action end, so that the sixth cylinder 71 can provide a greater riveting driving force through its equal level of pressure. The riveting rod 74 is limited in a guide slot so that it can only move forward and backward, ensuring that the riveting head 75 can only perform riveting actions forward and backward.

[0050] This embodiment is a connecting rod steel ball spring full-automatic riveting machine 100, and the working principle is as follows:

[0051] 1) The operator puts multiple connecting rods into the connecting rod transfer channel 1 at one time, and the connecting rods located at the front inclined part automatically transfer to the horizontal part under the action of their own gravity;

[0052] 2) When the connecting rod angle correction unit 2 is reached, the front stopper unit 161 is extended first, and then the rear stopper unit 162 is extended to limit the frontmost connecting rod within the set area, and the rear stopper unit 162 blocks the connecting rod behind, and the first positioning card plate 95 and the second positioning card plate 81 are extended to limit the connecting rod, and then the connecting rod angle correction unit 2 is started, and the correction rod 24 drives the connecting rod to rotate to the correct angle position;

[0053] 3) The front stopper unit 162 retreats, the second positioning card plate 81 retracts, the first positioning card plate 95 moves to the right with the connecting rod for a set distance, and then the second positioning card plate 81 extends, and the first positioning card plate 95 retreats and moves to the left;

[0054] 4) The front stopper unit 162 extends, the rear stopper unit 162 retracts, a connecting rod is lowered, the first positioning card plate 95 extends, and steps 2-3 are repeated;

[0055] 5) The first connecting rod will be gradually moved to the position of the spring feeding unit 3 and the steel ball feeding unit 4 by the first positioning card plate 95. When reaching this position, the ejector rod 102 in the upper ejection mechanism 10 will push the connecting rod upward against the limit baffle 13, and then the material dividing block 52 will move to the ejection position, and the first ejection rod 64 and the second ejection rod 65 will extend through the first introduction hole 513 and the second introduction hole 514 respectively, and the springs and steel balls will be ejected into the receiving holes of the connecting rods in turn at the two stations;

[0056] 6) The connecting rod with the spring and the steel ball pressed in sequence will move to the riveting unit 7 position in the next step. When it reaches this position, the sixth cylinder 71 drives the riveting head 75 to rivet the steel ball into the connecting rod, completing the assembly of the connecting rod;

[0057] 7) Then the connecting rod moves to the end of the connecting rod transfer channel 1 and falls into the material receiving channel 17 for material receiving.

[0058] The beneficial effects of the fully automatic riveting machine 100 for a connecting rod steel ball spring of the present embodiment are: it realizes the automatic assembly of the connecting rod steel ball spring, there will be no component missing phenomenon, and the assembly efficiency and assembly quality are greatly improved; the product transfer flow channel is arranged into two parts, the bottom is fixed and the upper part is movable, and the height difference between the two transfer flow channels can be flexibly adjusted according to the size of the connecting rod, which greatly improves the versatility of the equipment; it has a connecting rod angle adjustment function to ensure the accuracy of the connecting rod assembly.
