[0031] Preferably, the drive assembly 3 includes: a drive member 31; a transmission shaft 32, the drive member 31 is drivingly connected to the transmission shaft 32 to drive the transmission shaft 32 to rotate; a first eccentric wheel group 33, at least a portion of the first eccentric wheel group 33 is mounted on the transmission shaft 32; the output portion of the first eccentric wheel group 33 is rotatably connected to the input portion of the pushing assembly 4; a second eccentric wheel group 34, at least a portion of the second eccentric wheel group 34 is mounted on the transmission shaft 32, the second eccentric wheel group 34 is spaced apart from the first eccentric wheel group 33, and the output portion of the second eccentric wheel group 34 is rotatably connected to the input portion of the punching assembly 1; a third eccentric wheel group 35, at least a portion of the third eccentric wheel group 35 is mounted on the transmission shaft 32, the third eccentric wheel group 35 is spaced apart from the second eccentric wheel group 34, and the output portion of the third eccentric wheel group 35 is rotatably connected to the input portion of the riveting assembly 2.

[0032] By adopting the above technical solution, the driving member 31 drives the transmission shaft 32 to rotate, driving the first eccentric wheel group 33, the second eccentric wheel group 34 and the third eccentric wheel group 35 that are coaxially installed but spaced apart from each other to rotate synchronously, and then drives the pushing assembly 4 through the output part of the first eccentric wheel group 33, the punching assembly 1 through the output part of the second eccentric wheel group 34, and the riveting assembly 2 through the output part of the third eccentric wheel group 35, so that one driving source can accurately and independently control the specific reciprocating motion of the three actuators, thereby realizing complex composite processes such as efficient coordination and flexible adjustment of pushing, punching and riveting with a compact mechanical structure.

[0033] Specifically, the driving member 31 is a motor.

[0034] Furthermore, the motor is connected to the reducer, and the reducer is connected to the transmission shaft 32 .

[0035] Specifically, the first eccentric wheel group 33 includes: a first eccentric wheel 36, the first eccentric wheel 36 is installed on the transmission shaft 32; a first connecting arm 39, the input end of the first connecting arm 39 is connected to the first eccentric wheel 36; the output end of the first connecting arm 39 is rotatably connected to the input part of the pushing assembly 4, wherein the first connecting arm 39 forms the output part of the first eccentric wheel group 33; by arranging the first eccentric wheel 36 to be installed on the transmission shaft 32, and using the first connecting arm 39 to convert the rotational motion of the first eccentric wheel 36 into the specific motion (such as swinging) required by the input part of the pushing assembly 4, the movement of the pushing assembly 4 can be precisely driven and controlled, thereby realizing the motion trajectory (such as linear reciprocating) required for the pushing process.

[0036] The second eccentric wheel group 34 includes: a second eccentric wheel 37, the second eccentric wheel 37 is installed on the transmission shaft 32, and the second eccentric wheel 37 is spaced apart from the first eccentric wheel 36; a second connecting arm 40, the input end of the second connecting arm 40 is connected to the second eccentric wheel 37; the output end of the second connecting arm 40 is rotatably connected to the input part of the punching assembly 1, wherein the second connecting arm 40 forms the output part of the second eccentric wheel group 34; by arranging the second eccentric wheel 37 to be installed on the transmission shaft 32 and spaced apart from the first eccentric wheel 36, and using the second connecting arm 40 to convert the rotational motion of the second eccentric wheel 37 into the motion required by the input part of the punching assembly 1, the action of the punching assembly 1 can be independently driven and controlled, thereby realizing the strong, vertical reciprocating punching motion required for the punching process.

[0037] The third eccentric wheel group 35 includes: a third eccentric wheel 38, which is installed on the transmission shaft 32 and is spaced apart from the second eccentric wheel 37; a third connecting arm 41, the input end of the third connecting arm 41 is connected to the third eccentric wheel 38; the output end of the third connecting arm 41 is rotatably connected to the input part of the riveting assembly 2, wherein the third connecting arm 41 forms the output part of the third eccentric wheel group 35, and the third eccentric wheel 38 is installed on the transmission shaft 32 and is spaced apart from the second eccentric wheel 37, and the third connecting arm 41 is used to convert the rotational motion of the third eccentric wheel 38 into the motion required by the input part of the riveting assembly 2, so that the action of the riveting assembly 2 can be independently driven and controlled, thereby realizing the precise and powerful vertical reciprocating riveting motion required for the riveting process.

[0038] Furthermore, the length of the second connecting arm 40 is greater than the length of the third connecting arm 41; by making the length of the second connecting arm 40 driving the punching assembly 1 greater than the length of the third connecting arm 41 driving the riveting assembly 2, the lever principle is used to amplify the motion stroke of the second eccentric wheel 37 input to the punching assembly 1, so that the punching assembly 1 can obtain a larger vertical working stroke than the riveting assembly 2, meeting the requirement that the punching process usually requires a longer penetration distance, while ensuring that the riveting process can obtain a greater effective output force.

[0039] Furthermore, the radius of the first eccentric wheel 36 is smaller than the radius of the second eccentric wheel 37 or the third eccentric wheel 38; by making the radius of the first eccentric wheel 36 driving the pushing assembly 4 smaller than the radius of the second eccentric wheel 37 driving the punching assembly 1 or the third eccentric wheel 38 driving the riveting assembly 2, the lift (eccentric distance) generated when the first eccentric wheel 36 rotates is smaller than the lift of the second eccentric wheel 37 or the third eccentric wheel 38, and correspondingly, the motion amplitude required by the pushing assembly 4 is smaller than the motion amplitude required by the punching assembly 1 or the riveting assembly 2, thereby optimizing the matching between the motion characteristics and output requirements of each actuator (pushing, punching, riveting), making the pushing action smoother and lighter, and the punching and riveting actions can obtain a larger effective working stroke to meet their process requirements.

[0040] Please refer to Figure 1 The stamping riveting machine also includes: a vertical plate 5, which extends in the vertical direction; a pushing assembly 4 has a pushing part and a first transmission part, the pushing part is movably arranged along a first preset direction, the first transmission part is movably arranged, the first transmission part is drive-connected to the driving assembly 3, and the first output end of the first transmission part is drive-connected to the pushing part; the driving assembly 3 drives the first transmission part to move, so that the first transmission part drives the pushing part to move.

[0041] By adopting the above technical solution, the driving component 3 drives the first transmission part of the pushing component 4 to move, and then drives the pushing part to perform precise linear displacement along a first preset direction (such as a horizontal direction) through the first output end of the first transmission part, so that the pushing action (such as pushing the first workpiece to the riveting station) can be performed stably and reliably, providing a precise workpiece positioning basis for subsequent punching and riveting processes.

[0042] Please refer to Figure 2 The pushing assembly 4 includes: a pushing rod 6, which extends along a first preset direction and is used to push the first workpiece to the bottom of the riveting assembly 2; a moving seat 7, which is movably arranged along the first preset direction, and the pushing rod 6 is arranged on the moving seat 7; a slide rail 8, which extends along the first preset direction, and the moving seat 7 is movably arranged on the slide rail 8; a first connecting rod 9, one end of which is rotatably arranged on one side of the moving seat 7; a first transmission arm 10, which is rotatably arranged on the vertical plate 5, and the first transmission arm 10 is drivingly connected to the driving assembly 3, and the first output end of the first transmission arm 10 is rotatably connected to the end of the first connecting rod 9 away from the moving seat 7; The first transmission arm 10 forms the input portion of the pusher assembly 4 , and the input end of the first transmission arm 10 is rotatably connected to the first connecting arm 39 .

[0043] By adopting the above-mentioned technical solution, the first connecting arm 39 drives the first transmission arm 10 to rotate, and then the rotation of the first transmission arm 10 is converted into a stable linear sliding of the moving seat 7 along the slide rail 8 through the first connecting rod 9, and finally drives the pushing rod 6 fixed on the moving seat 7 to complete the action of pushing the first workpiece, so that the pushing process of the first workpiece has high linear accuracy, low friction resistance and reliable repeatable positioning, effectively preventing material jamming and positioning deviation.

[0044] Please refer to Figure 2 The punching assembly 1 includes: a punch rod 11, the punch rod 11 is movably arranged in the vertical direction, and a punch is installed on the punch rod 11; a second connecting rod 12, one end of the second connecting rod 12 is rotatably arranged with one end of the punch rod 11; a second transmission arm 13, the middle part of the second transmission arm 13 is rotatably arranged on the vertical plate 5, the input end of the second transmission arm 13 is drive-connected to the driving assembly 3, and the output end of the second transmission arm 13 is rotatably connected to the second connecting rod 12; the second transmission arm 13 is driven to move by the driving assembly 3, so that the second transmission arm 13 drives the punch rod 11 to move through the second connecting rod 12.

[0045] By adopting the above-mentioned technical solution, the second connecting arm 40 drives the second transmission arm 13 to rotate, and then the rotation of the second transmission arm 13 is converted into a strong linear punching movement of the punch rod 11 in the vertical direction through the second connecting rod 12, so that the punch installed on the punch rod 11 can accurately and efficiently complete the punching operation on the second workpiece, providing sufficient stroke, punching force and vertical guide accuracy required for punching.

[0049] By adopting the above technical solution, the third connecting arm 41 drives the third transmission arm 17 to rotate, and then transmits the motion to the riveting rod 14 through the connecting member 16 and the third connecting rod 15, so that the riveting rod 14 can perform precise reciprocating motion along the riveting direction within the limited space of the positioning seat 18. At the same time, the punch rod 11 can move independently in the sliding space of the riveting rod 14 and the second connecting rod 12 moves in the avoidance space of the connecting member 16, so that the punching and riveting actions can be highly integrated in space but completely decoupled in motion, ensuring that the two key processes can be executed independently, forcefully and accurately without interfering with each other.

[0050] Please refer to Figure 1 The stamping riveting machine also includes: a flap assembly 19, and the riveting assembly 2 can slide relative to the flap assembly 19, wherein the riveting assembly 2 drives the flap assembly 19 to move along the riveting direction to make the second workpiece close to the first workpiece matching the second workpiece, and then the riveting assembly 2 continues to move relative to the flap assembly 19 along the riveting direction to apply force to the second workpiece and the first workpiece after they are close to each other, so as to achieve the buckling of the second workpiece and the first workpiece.

[0052] By adopting the above technical solution, the riveting rod 14 first drives the flap assembly 19 to move as a whole along the riveting direction, so that the upper button carried on the flap assembly 19 approaches and is precisely aligned with the first workpiece below. Then, the riveting rod 14 continues to move along the riveting direction relative to the flap assembly 19, and directly applies force to the aligned upper and lower buttons to achieve fastening, so that the automatic positioning and conveying of the upper button and the final riveting force are integrated into a single continuous action sequence, eliminating the need for additional loading stations, significantly simplifying the structure, and improving positioning accuracy and production efficiency.

[0053] Furthermore, the flap assembly 19 includes: a connecting plate 20, which extends in the vertical direction and is mounted on one side of the positioning seat 18.

The release member 24 has a placement state and a release state for the second workpiece; when the riveting rod 14 moves downward and applies force to the release member 24, the release member 24 is in the release state, and the second workpiece placed in the placement space moves downward until it leaves the placement space and is aligned with the first workpiece. When the riveting rod 14 is away from the release member 24, the release member 24 is in the placement state.

[0054] By adopting the above technical solution, the flap assembly 19 extends in the vertical direction through the connecting plate 20 and is installed on one side of the positioning seat 18, providing a stable installation foundation and precise vertical movement guide for the entire assembly; the first protrusion 21 and the second protrusion 22 arranged at intervals along the width direction of the connecting plate 20 constitute a reliable support structure; the two positioning plates 23 are respectively connected to the first protrusion 21 and the second protrusion 22 and are located at the bottom of the positioning seat 18, forming a direct and stable installation platform for the release member 24, ensuring that the release member 24 and the second workpiece it carries can be accurately positioned at the riveting station; the release member 24 is rotatably arranged at the bottom of the positioning plate 23, and its designed placement space and feed port allow external feeding components to feed the second workpiece in sequence; when the riveting rod 14 is away, the release member 24 is in a placed state When the riveting rod 14 moves downward and applies force to the release member 24, the release member 24 is triggered to rotate and enter the released state, so that the second workpiece in the placement space falls accurately until it is aligned with the first workpiece below; then the riveting rod 14 continues to move downward to complete the riveting, and when it returns away, the release member 24 automatically resets to the placement state to prepare for receiving the next workpiece, realizing the automatic reception of the second workpiece, precise positioning and temporary storage, and timed precise release and alignment functions that are strictly linked to the riveting action, eliminating the need for additional loading robots or complex positioning mechanisms. Through a simple and reliable mechanical structure and direct power linkage with the riveting rod 14, the key steps of conveying and positioning the second workpiece before riveting are completed efficiently and accurately, significantly improving the degree of automation, assembly accuracy and production continuity.

[0055] Furthermore, the release member 24 includes three jaws, which are arranged in sequence, with two jaws arranged opposite to each other and the other jaw arranged toward the feed port. The three jaws enclose a placement space, and the three jaws are rotatably arranged at the bottom of the connecting plate 20 and the bottom of the two positioning plates 23 toward the placement space. This layout allows the three jaws to rotate inward to clamp the workpiece and rotate outward to completely release the workpiece. Furthermore, each of the three clamping jaws is provided with a placement slot, which is located in the same plane and is specifically used to receive and place the second workpiece input from the feed port, ensuring that the workpiece is horizontally and stably supported in the predetermined position, effectively preventing the workpiece from tilting or shaking in the placement state; Furthermore, a magnet is provided in a placement slot on one side of one of the clamping jaws (preferably the clamping jaw facing the feed inlet) close to the placement space. The magnetic attraction is used to assist in the adsorption and positioning of a second workpiece (usually made of metal) placed in the slot. This significantly enhances the stability of the workpiece during the temporary storage stage, effectively resists vibrations or slight displacements that may occur during the operation of the equipment, and ensures that the workpiece maintains a precise positioning posture before release. By adopting the above technical solution, a mechanical clamping and releasing mechanism with a simple and reliable structure and precise action is provided. The placement space formed by the layout of the clamping claws, the placement groove located in the same plane and the auxiliary magnetic limiter are used to collaboratively realize the reception, positioning and temporary storage of the second workpiece, and it is reliably released when triggered by the riveting rod 14, which greatly ensures the accuracy of the alignment of the second workpiece with the first workpiece after release, and improves the riveting quality and production continuity.

[0056] Please refer to Figure 1 The stamping riveting machine also includes: a sorting component 25, the sorting component 25 has a placing part and a sorting part, the sorting part is movably arranged in the vertical direction, the placing part has a discharge space and a feeding port connected to the discharge space, a first workpiece is placed in the discharge space, and the first workpiece is transported through the feeding port by an external feeding component, at least part of the sorting part is movably arranged in the discharge space to sort the inclined first workpiece placed in the discharge space so that the first workpiece is in a horizontal state; the pushing part is movably arranged in the discharge space along a first preset direction, when the pushing part pushes the first workpiece to move along the first preset direction, the pushing part drives the sorting part to move upward, and when the pushing part is away from the placing part, the second output end of the first transmission part drives the sorting part to move downward.

[0057] By adopting the above technical solution, the sorting component 25 provides a discharge space and a feeding port for accommodating the first workpiece through its placement part, and the sorting part can be movably arranged in the discharge space in the vertical direction, so that when the pushing part is not in action, the sorting part can be driven by the second output end of the first transmission part to descend and press down the first workpiece that may be tilted or stacked incorrectly in the discharge space to sort it, ensuring that the workpiece to be pushed is in the correct horizontal posture; at the same time, when the pushing part passes through the discharge space and pushes the first workpiece to move along the first preset direction, the pushing part synchronously drives the sorting part to move upward to make way for the pushing of the workpiece; and when the pushing part retreats away from the placement part, the second output end of the first transmission part drives the sorting part to descend and reset again, preparing for the next sorting, and automatically completes the correction of the first workpiece posture before each pushing action, effectively preventing pushing jams, inaccurate positioning or riveting dislocation caused by poor workpiece posture, significantly improving production continuity and product yield, and the entire sorting action is closely linked with the pushing process, without the need for an additional power source, and the structure is ingenious and efficient.

[0058] Please refer to Figure 3 , the sorting assembly 25 includes: a discharge seat 29, the discharge seat 29 has a discharge space, and a first workpiece is placed in the discharge space; a movable part 26, at least a portion of the movable part 26 is movably arranged in the discharge space along the vertical direction; a limit member 27, the limit member 27 is mounted on the vertical plate 5, and the limit member 27 is located above the movable part 26; a spring is provided between the movable part 26 and the limit member 27, a transmission rod 30, the transmission rod 30 extends in the vertical direction, the transmission rod 30 is connected to the movable part 26, the transmission rod 30 passes through the limit member 27, and is movably arranged in the vertical direction relative to the limit member 27; a linear bearing 28, the linear bearing 28 is mounted on the limit member 27, the transmission rod 30 is movably arranged relative to the linear bearing 28, and the linear bearing 28 is located above the limit member 27; wherein, the discharge seat 29 forms a placement portion; the movable part 26, the limit member 27, and the transmission rod 30 form a sorting portion.

[0059] By adopting the above technical solution, the discharge seat 29 forms a placement portion and provides a discharge space; the movable part 26 is the part that directly contacts the workpiece, and at least part of it is movably arranged in the discharge space to perform the downward pressing and sorting action; the transmission rod 30 extends in the vertical direction and is connected to the movable part 26 to transmit the lifting movement; the limit part 27 is installed on the vertical plate 5 and is located above the movable part 26, and the transmission rod 30 is passed through it and is movable to provide movement guidance; the spring is used to provide pulling force to the movable part 26, and when the transmission rod 30 loses pressure, the movable part 26 is pulled out of the discharge space by the pulling force of the spring; the transmission rod 30 is slidably connected to the linear bearing 28, and the linear bearing 28 is used to provide guided sliding for the transmission rod 30. The invention provides an implementation scheme of a sorting mechanism with a simple structure and reliability. The movable part 26 directly acts on the workpiece for sorting. The transmission rod 30 ensures the vertical accuracy of the movement and the force transmission. The limiter 27 provides the guide constraint. The linear bearing 28 is used to provide the guide sliding. The combination of the spring and the limiter 27 controls the lifting and lowering of the sorting part, which not only ensures the effectiveness of the sorting action (can fully press down the workpiece) but also avoids structural interference or waste of resources caused by excessive rise. The overall structure has good rigidity and stable action, and the automatic sorting function is reliably realized.

[0060] Working principle: First, before the start of processing, the first workpiece and the second workpiece are both located in the corresponding two processing positions. After the motor is started, the transmission shaft 32 is driven to rotate through the reducer. All actions are triggered simultaneously. The punching action is completed first, and then the riveting action is completed. During this process, the transmission shaft 32 synchronously drives the coaxially installed first eccentric wheel group 33 (including the first eccentric wheel 36 and the first connecting arm 39), the second eccentric wheel group 34 (including the second eccentric wheel 37 and the second connecting arm 40) and the third eccentric wheel group 35 (including the third eccentric wheel 38 and the third connecting arm 41) to rotate; the punching action is triggered - the second eccentric wheel 37 passes through the long stroke The second connecting arm 40 drives the second transmission arm 13 to rotate, and the second transmission arm 13 pushes the punch 11 to move vertically downward through the second connecting rod 12, and the punch punches the positioned first workpiece; the riveting action is performed immediately afterwards - the third eccentric wheel 38 drives the third transmission arm 17 to rotate through the third connecting arm 41, and the third transmission arm 17 pushes the riveting rod 14 downward through the connecting piece 16 and the third connecting rod 15: first, the riveting rod 14 presses down the release piece 24, so that the three clamps rotate to release the second workpiece and fall to align with the first workpiece; then the riveting rod 14 continues to move downward, and independently applies force to complete the riveting (during the process, the punch 11 is in the sliding space of the riveting rod 14). During this process, the pushing action is triggered - the first eccentric wheel 36 drives the first transmission arm 10 to rotate around the vertical plate 5 through the first connecting arm 39, and the first transmission arm 10 pushes the movable seat 7 and the push rod 6 to slide horizontally along the slide rail 8 through the first connecting rod 9 and retreats to the initial position. The external feeding assembly feeds the material into the discharge space. After feeding, the first transmission arm 10 presses the transmission rod 30 downward, so that the movable part 26 enters the discharge space, completing the sorting action of the first workpiece. Subsequently, the first transmission arm 10 drives the movable seat 7 and the push rod 6 to slide horizontally along the slide rail 8. The push rod 6 slides and penetrates the discharge space of the discharge seat 29, pushing the first workpiece to move toward the riveting station (at the same time, the rotation of the first transmission arm 10 causes the movable part 26 to leave the discharge space under the action of the spring tension, and the transmission rod 30 moves up along the linear bearing 28 to make way for the next placement of the first workpiece); while pushing the material, the riveting rod 14 and the punch 11 return to their initial positions, and the first workpiece pushed out is prepared for the next start; after the riveting rod 14 returns to its initial position, the clamping claw of the release part 24 rotates to the placement state under the action of the spring, and the external feeding component replenishes new workpieces through the feeding port and the feeding port respectively.
