Description

Technical Field

[0001] This invention relates to the field of chain assembly technology, specifically to a dual-station synchronous operation chain high-speed assembly mechanism and its assembly method. Background Technology

[0002] Chains, as a core component of mechanical transmission systems, are widely used in various fields such as industrial production, transportation, and agricultural machinery. With the continuous advancement of industrialization, the market demand for chain products continues to grow, and the requirements for chain assembly efficiency and quality are also increasing.

[0003] Existing chain assembly technology suffers from four main shortcomings: First, low assembly efficiency. Most existing chain assembly equipment employs a single-station, piece-by-piece assembly method, with each part being assembled sequentially and individually. This results in slow assembly speed and low output per unit time, failing to meet the demands of large-scale industrial production and severely restricting manufacturers' capacity expansion and market responsiveness. Second, insufficient assembly precision. Existing equipment lacks precise positioning control mechanisms during part placement, leading to significant deviations in part placement and uneven clearances between components. This easily results in assembly defects such as misalignment, skewness, and omissions, leading to low product qualification rates, substantial rework, increased production costs, and greater difficulty in quality control. Third, fragmented processes and low integration. Chain assembly and surface rust prevention are separate processes. After assembly, the product needs to be transferred to the rust prevention station for secondary processing, resulting in long production cycles, large equipment footprint, and the risk of parts being damaged during material handling, affecting product appearance and performance. Fourth, there is a serious waste of resources. Most existing rust prevention equipment adopts continuous spraying, with rust inhibitor sprayed continuously and without interruption. Regardless of whether the chain passes through the spraying area, a constant flow rate is maintained, resulting in a large amount of rust inhibitor being wasted without load. The cost of consumables remains high. At the same time, excessive spraying can also cause droplets to splash and pollute the working environment, increasing the burden of environmental protection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dual-station synchronous operation chain high-speed assembly mechanism and its assembly method, which solves four prominent problems in existing chain assembly technologies: low assembly efficiency, insufficient assembly accuracy, low integration of processes, and serious waste of resources.

The rear end of each discharge plate is fixedly connected to the same plate. The plate is horizontally arranged along the length of the discharge shell, and the end of the second traction plate is rotatably connected to the plate.

[0008] Preferably, the column-placing shaft is vertically arranged and rotatably connected inside the loading platform. Both the upper and lower ends of the column-placing shaft are provided with semicircular plates. The upper and lower semicircular plates are offset by 180 degrees. The upper semicircular plate corresponds to the bottom outlet of the cylindrical groove, and the lower semicircular plate corresponds to the arc-shaped groove. When the column-placing shaft rotates half a turn, the opening of the upper semicircular plate aligns with the bottom outlet of the cylindrical groove, and the lower semicircular plate closes the falling channel. When the column-placing shaft rotates another half turn, the upper semicircular plate closes the bottom outlet of the cylindrical groove, and the opening of the lower semicircular plate aligns with the arc-shaped groove.

[0009] Preferably, the bottom outlet of the second cylindrical groove is connected to the side wall of the first cylindrical groove, the inside of the second cylindrical groove is provided with a pin-like material, the middle of the rod of the column shaft is provided with a radial through hole, the radial through hole corresponds to the position of the bottom outlet of the second cylindrical groove, and the radial through hole is intermittently aligned with the bottom outlet of the second cylindrical groove when the column shaft rotates.

[0010] Preferably, the stamping device is a hydraulically driven structure. The bottom end of the cylinder of the stamping device is fixedly connected to the bottom support of the base. The piston rod of the stamping device extends upward and passes through the bottom wall of the base. The connecting frame is an L-shaped plate structure. The vertical section of the connecting frame is fixedly connected to the driving end of the stamping device. The bottom end of the horizontal section of the connecting frame is fixedly connected to the top end of the stamping plate. The stamping plate is located directly above the arc groove. A stamping die is provided on the bottom surface of the stamping plate.

[0011] Preferably, the transmission shafts are arranged at uniform intervals along the length of the arc groove, both ends of the transmission shafts are rotatably connected to the sidewall of the arc groove, the top of each transmission shaft is higher than the bottom surface of the arc groove, the axis of each transmission shaft is perpendicular to the length of the arc groove, and the outer wall of the transmission shaft is provided with a wear-resistant coating.

[0012] Preferably, a control housing is fixedly connected to the top of the nozzle. The control housing has a rectangular shell structure and a liquid storage chamber is provided inside the control housing. The delivery pipe is inserted into the liquid storage chamber from the side wall of the control housing. The top of the nozzle has multiple through holes arranged in a matrix. The bottom surface of the cover plate is in close contact with the top surface of the nozzle. The cover plate has openings corresponding to the through holes. The cam is fixedly connected to the top of the front transmission rod.

[0013] A high-speed assembly method for a dual-station synchronous operation chain includes the following steps: Step S1: Start motor two. Motor two drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, and the worm wheel drives the column shaft to rotate. When the upper semicircular piece of the column shaft rotates to the open position, the column material in the column groove one falls into the lower semicircular piece of the column shaft. After the column shaft continues to rotate half a turn, the opening of the lower semicircular piece aligns with the arc groove, and the column material falls into the part material in the arc groove. At the same time, the pin-like material in the column groove two is put into the column material through the radial through hole in the middle of the column shaft. Step S2: Start motor one. Motor one drives transmission rod one to rotate. Cam one at the top of transmission rod one rotates synchronously. Cam one drives the feeding plate inside the feeding shell one to slide back and forth through traction plate one. After the parts and materials in the feeding trough fall into the receiving groove of the feeding plate, they are pushed by the feeding plate to the inclined platform and slide along the inclined platform into the arc groove of the base. Step S3: Start motor three. Motor three drives the conveying pipe to rotate. The conveying pipe drives the feeding plates in feeding shell two, feeding shell three and feeding shell four to move back and forth synchronously through traction plate two. The plate-shaped materials in feeding shell two, feeding shell three and feeding shell four fall intermittently into the arc-shaped groove through their respective inclined platforms, completing the pre-selection assembly of each component of the chain. In step S4, the assembled chain assembly is conveyed along the transmission shaft to the area below the stamping plate. The driving end of the stamping device retracts, causing the connecting frame to move downward. The connecting frame drives the stamping plate to press against the chain surface, completing the extrusion stamping process. In step S5, transmission rod one drives transmission rod two to rotate via the transmission belt assembly, transmission rod two drives transmission rod three to rotate via the gear assembly, and transmission rod three drives the transmission sprocket to rotate. The two transmission sprockets rotate relative to each other, driving the processed chain forward. In step S6, the cam three at the top of the transmission rod three rotates synchronously. The cam three drives the traction frame to move back and forth through the traction plate three. The traction frame drives the cover plate to slide back and forth at the top of the nozzle, so that the through hole above the nozzle opens intermittently. The rust-preventive liquid enters the control housing through the delivery pipe and is sprayed out from the nozzle to perform rust prevention treatment on the chain that passes through.

[0014] Preferably, in step S1, the column shaft completes the feeding of one cylindrical material and one pin-type material per revolution; in step S2, the cam completes the feeding of one part material per revolution; in step S3, the conveying pipe completes the feeding of three plate-shaped materials per revolution; and in step S6, the frequency of the reciprocating movement of the cover plate matches the speed of the chain conveyor, so that the through hole opens precisely when each link of the chain passes under the nozzle.

[0015] Working principle: The whole machine is supported by the base. The transmission shaft in the arc groove forms the part conveying channel. Each material discharge shell and loading platform is arranged in sequence along the conveying direction. The material is put into the arc groove from each station to complete the pre-selection assembly. After being stamped by the stamping device, it is sent out by the transmission sprocket. The surface anti-rust treatment is completed at the discharge end at the same time. The first station unloading is completed independently by the unloading shell. When the motor is running, it drives the transmission rod to rotate. The cam at the top of the transmission rod rotates synchronously. The traction plate connected to the outer wall of the cam converts the rotational motion into horizontal reciprocating motion, pulling the unloading plate in the unloading shell to slide horizontally along the inner wall. The chain parts in the unloading groove fall into the receiving groove of the unloading plate under gravity. They are pushed forward by the unloading plate to the inclined platform and slide into the arc groove of the base platform along the inclined surface, completing a single unloading of the basic parts. Each time the cam rotates once, the unloading plate completes one reciprocating motion, corresponding to one unloading of a part. The second station's material unloading is completed simultaneously by unloading shells two, three, and four. Motor three at the bottom of the fixed frame drives the conveying pipe to rotate. The traction plate two, which is rotatably connected to the conveying pipe, converts the rotational motion into linear reciprocating motion, causing the plates connected to the rear ends of the unloading plates in the three unloading shells to move horizontally. This synchronously drives the three unloading plates to move forward and backward within their respective shells. The unloading troughs at the top of the three unloading shells hold different specifications of plate-shaped materials. After the materials fall onto the unloading plates, they are pushed to their respective inclined platforms and slide along the inclined surfaces into the arc-shaped grooves to cooperate with the previously placed basic parts. Each time the conveying pipe rotates once, the three unloading plates synchronously complete one reciprocating motion, corresponding to the sequential unloading of the three types of plate-shaped materials. The precise delivery of cylindrical materials and pins is controlled by the column-dispensing shaft inside the loading platform. Motor 2 drives the worm gear to rotate, which in turn drives the meshing worm wheel to rotate synchronously. The worm wheel drives the column-dispensing shaft to rotate vertically inside the loading platform. The column-dispensing shaft has a semi-circular plate at each of its upper and lower ends, which are staggered by 180 degrees. When the column-dispensing shaft rotates half a turn, the opening of the upper semi-circular plate aligns with the bottom outlet of the first cylindrical groove. The cylindrical material falls to the lower semi-circular plate under gravity for temporary storage. At this time, the lower semi-circular plate is in a closed state to prevent the material from falling directly. After the column-dispensing shaft continues to rotate half a turn, the upper semi-circular plate returns to the closed position to block the outlet of the first cylindrical groove to prevent subsequent material from falling. The opening of the lower semi-circular plate aligns with the arc groove, and the temporarily stored cylindrical material falls into the groove onto the parts that are already in place. At the same time, the pin-like material in the second cylindrical groove is simultaneously put into the cylindrical material through the radial through hole in the middle of the column-dispensing shaft, completing the precise assembly of the column-pin combination. The column-dispensing shaft completes one combination delivery of cylindrical material and pins every time it rotates. The stamping assembly process is driven by the stamping device. The pre-assembled chain assembly is gradually conveyed forward along the transmission shaft in the arc groove to the area directly below the stamping plate. The driving end of the stamping device retracts, causing the L-shaped connecting frame to move downward. The stamping plate at the bottom of the horizontal section of the connecting frame moves downward and stamps on the chain surface, making the components tightly joined to complete the extrusion stamping process. After the stamping is completed, the driving end of the stamping device extends, causing the stamping plate to move upward and reset, waiting for the next set of chain assemblies to enter the stamping station. The chain conveyor is synchronously driven by transmission rod one through a transmission chain. The transmission wheel at the bottom of transmission rod one drives the transmission wheel at the bottom of transmission rod two to rotate through the transmission belt, so that transmission rod two rotates synchronously. The driving gear at the top of transmission rod two drives the front transmission rod three to rotate through the meshing driven gear. The transmission sprockets on the front and rear transmission rods three rotate relative to each other. The teeth are embedded in the gaps between the chain links, driving the completed chain to be continuously conveyed along the discharge direction. The conveying speed and the feeding frequency are kept synchronously matched to ensure that the material feeding at each station is consistent with the chain movement rhythm. Intermittent rust-preventive spraying is synchronously driven by the transmission shaft of the transmission sprocket. The cam three at the top of the front transmission rod three rotates synchronously with the transmission sprocket. The traction plate three connected to the outer wall of the cam three drives the traction frame to perform reciprocating linear motion. The cover plate at the end of the traction frame slides horizontally on the top surface of the nozzle. The rust-preventive liquid is sent into the liquid storage chamber of the control housing through the delivery pipe. The cover plate has an opening corresponding to the nozzle through hole. When the cover plate slides to the point where the opening is aligned with the nozzle through hole, the rust-preventive liquid is sprayed out. When it is misaligned, the through hole is closed and spraying stops. The reciprocating frequency of the cover plate is matched with the chain conveying speed. The through hole opens exactly when each chain link passes under the nozzle, realizing intermittent rust prevention treatment that is sprayed only when the chain passes by, which ensures the rust prevention effect and avoids idle waste.

[0016] This invention provides a dual-station synchronous operation chain high-speed assembly mechanism and its assembly method. It has the following beneficial effects: 1. This invention uses a dual-station structure where a motor drives a cam to independently feed material from a feeding shell, and a motor drives a traction plate to simultaneously feed material from feeding shells two, three, and four. This achieves parallel feeding and assembly of chain parts, significantly improving assembly speed and increasing production efficiency to meet the needs of mass production.

[0017] 2. This invention controls the sequential falling of cylindrical materials by the staggered rotation of the semicircular plates at the upper and lower ends of the column shaft, and achieves precise delivery of pin-type materials by intermittently aligning the cylindrical groove two with the radial through hole in the middle of the column shaft. This ensures that each part can accurately fall into the predetermined position in the arc groove, thereby improving assembly accuracy, reducing misalignment defects, and increasing product qualification rate.

[0018] 3. This invention integrates a nozzle and control housing at the discharge end of the base, and uses a synchronous transmission structure with a transmission sprocket to transport the chain. This allows the chain to directly enter the anti-rust treatment station after assembly, eliminating the need for intermediate transfer links, shortening the production process, achieving integrated operation, reducing equipment footprint, and improving production continuity.

[0019] 4. This invention uses the rotation of the cam three to drive the reciprocating motion of the traction plate three and the traction frame, and with the intermittent opening and closing control of the cover plate at the top of the nozzle, the rust inhibitor is sprayed only when the chain passes by, avoiding waste due to no-load operation. At the same time, the spraying amount is uniform and stable, achieving the effects of saving rust inhibitor consumables, reducing production costs, and reducing environmental pollution.

The end of the traction plate 2 (21) rotatably connected to the conveying pipe 18 is connected to the connecting plate. When motor 3 (34) operates, it drives the connecting plate to reciprocate linearly via traction plate 2 (21), thereby synchronously driving the feeding plates 22 in the three feeding shells to move forward and backward simultaneously, achieving synchronous intermittent unloading of three types of plate materials. The two unloading stations are driven by independent motors, and the unloading frequency can be adjusted according to the assembly rhythm. Feeding shell 1 (6) is responsible for the placement of basic parts, while feeding shells 2 (9), 3 (10), and 4 (11) are responsible for the sequential placement of different specifications of plate parts. Together, they complete the pre-selection assembly of each component of the chain, significantly improving assembly efficiency compared to the single-station piece-by-piece unloading method.

The vertically mounted column-dispensing shaft 27 inside the loading platform 7 is driven to rotate by a motor 24 via a worm gear assembly. The column-dispensing shaft 27 has a semi-circular plate at both its upper and lower ends, staggered by 180 degrees. The upper semi-circular plate corresponds to the bottom outlet of the cylindrical groove 25, and the lower semi-circular plate corresponds to the arc-shaped groove. When the column-dispensing shaft 27 rotates half a turn, the opening of the upper semi-circular plate aligns with the outlet of the cylindrical groove 25, and the cylindrical material in the groove falls into the lower semi-circular plate. At this time, the lower semi-circular plate closes the falling channel to prevent the material from falling directly. After the column-dispensing shaft 27 continues to rotate half a turn, the upper semi-circular plate returns to the closed position, blocking the outlet of the cylindrical groove 25 to prevent subsequent material from falling. The opening of the lower semi-circular plate aligns with the arc-shaped groove, and the caught cylindrical material falls onto the parts in the arc-shaped groove, completing a single precise delivery. The bottom outlet of the cylindrical groove 26 is connected to the side wall of the cylindrical groove 1 25. The middle part of the rod of the column shaft 27 has a radial through hole. During the rotation of the column shaft 27, the radial through hole is intermittently aligned with the outlet of the cylindrical groove 26. The pin-type material is put into the cylindrical material through the through hole to realize the synchronous assembly of the pin. After the chain is assembled, it is transported to the discharge end by the transmission sprocket 17. The nozzle 32 set above the fixed shell 5 performs rust prevention treatment on the chain surface. The control shell 33 at the top of the nozzle 32 has a liquid storage chamber inside. The conveying pipe 18 is connected from the side wall to supply rust prevention liquid. The cam 28 at the top of the front transmission rod 15 rotates synchronously with the transmission sprocket 17. Through the traction plate 29 and the traction frame 30, the cover plate 31 is driven to slide back and forth at the top of the nozzle 32. The cover plate 31 has openings corresponding to the through holes of the nozzle 32. During the sliding process, the through holes open intermittently, so that the rust prevention liquid is sprayed only when the chain passes by, which not only ensures the rust prevention effect but also reduces idle waste, realizing the integrated continuous operation of assembly and rust prevention.

[0031] A high-speed assembly method for a dual-station synchronous operation chain includes the following steps: Step S1: Start motor 24. Motor 24 drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the column shaft 27 to rotate. When the upper semicircular plate of the column shaft 27 rotates to the open position, the column material in the first column groove 25 falls into the lower semicircular plate of the column shaft 27. After the column shaft 27 continues to rotate half a turn, the opening of the lower semicircular plate aligns with the arc groove, and the column material falls into the part material in the arc groove. At the same time, the pin-like material in the second column groove 26 is put into the column material through the radial through hole in the middle of the column shaft 27. The column shaft 27 completes the feeding of column material and pin-like material once every rotation. Step S2: Start motor 4. Motor 4 drives transmission rod 13 to rotate. Cam 19 at the top of transmission rod 13 rotates synchronously. Cam 19 drives the feeding plate 22 in the feeding shell 6 to slide back and forth through traction plate 20. After the parts and materials in the feeding trough 16 fall into the receiving groove of feeding plate 22, they are pushed by feeding plate 22 to the inclined platform 23 and slide along the inclined platform 23 into the arc groove of base 1. Cam 19 completes one feeding of parts and materials with each rotation. Step S3: Start motor 34. Motor 34 drives conveyor pipe 18 to rotate. Conveyor pipe 18 drives the discharge plates 22 in discharge shell 29, discharge shell 30 and discharge shell 41 to move synchronously back and forth through traction plate 21. Plate-shaped materials in discharge shell 29, discharge shell 30 and discharge shell 41 fall intermittently into the arc-shaped groove through their respective inclined platforms 23, completing the pre-selection assembly of each component of the chain. Conveyor pipe 18 completes the feeding of plate-shaped materials three times for each rotation. In step S4, the assembled chain assembly is conveyed along the transmission shaft 12 to the area below the stamping plate 3. The driving end of the stamping device 2 retracts, causing the connecting frame to move downward. The connecting frame causes the stamping plate 3 to press against the chain surface, completing the extrusion stamping process. In step S5, transmission rod 13 drives transmission rod 2 14 to rotate via the transmission belt assembly. Transmission rod 2 14 drives transmission rod 3 15 to rotate via the gear assembly. Transmission rod 3 15 drives transmission sprocket 17 to rotate. The two transmission sprockets 17 rotate relative to each other, driving the processed chain forward. In step S6, the cam 28 at the top of the transmission rod 315 rotates synchronously. The cam 28 drives the traction frame 30 to move back and forth through the traction plate 329. The traction frame 30 drives the cover plate 31 to slide back and forth at the top of the nozzle 32, so that the through hole above the nozzle 32 is opened intermittently. The rust inhibitor enters the control housing 33 through the delivery pipe 18 and is sprayed out from the nozzle 32 to perform rust prevention treatment on the passing chain. The frequency of the reciprocating movement of the cover plate 31 matches the chain conveying speed, so that the through hole is just open when each chain link passes under the nozzle 32.

[0032] Example 4:

[0033] This embodiment describes the specific implementation process of the high-speed assembly method of the dual-station synchronous operation chain. After the equipment is started, motor 24 starts running first, driving the worm gear to rotate. The worm gear drives the meshing worm wheel to rotate synchronously. The worm wheel drives the column release shaft 27 to rotate vertically inside the loading platform 7. As the column release shaft 27 rotates, the semi-circular plate at the upper end gradually aligns with the bottom outlet of the cylindrical groove 25. The cylindrical material in the cylindrical groove 25 falls to the lower semi-circular plate of the column release shaft 27 under gravity for temporary storage. At this time, the lower semi-circular plate is in a closed state to prevent... The material falls directly, and after the column shaft 27 continues to rotate half a turn, the upper semicircular piece rotates back to the closed position to block the outlet of the first column groove 25 and prevent the subsequent material from falling. The opening of the lower semicircular piece is aligned with the arc groove of the base 1, and the temporarily stored column material falls into the part material that has been positioned in the arc groove. At the same time, the pin-like material in the second column groove 26 is simultaneously put into the column material through the radial through hole in the middle of the column shaft 27 to complete the pin assembly. The column shaft 27 completes the precise delivery of column material and pin-like material once every rotation. At the same time, motor 4 starts running, driving transmission rod 13 to rotate. Cam 19, which is fixed at the top of transmission rod 13, rotates synchronously. Cam 19 pulls the discharge plate 22 in discharge shell 6 through traction plate 20 connected to the outer wall to slide horizontally back and forth. The parts and materials in discharge trough 16 fall one by one into the receiving groove of discharge plate 22. The discharge plate 22 pushes them to the inclined platform 23 at the bottom of discharge shell 6. They slide along the inclined surface of inclined platform 23 into the arc groove of base 1 to complete the basic parts placement. Cam 19 completes one part placement for each rotation. The motor 34 at the bottom of the fixed frame 8 starts synchronously, driving the conveying pipe 18 to rotate. The conveying pipe 18 drives the discharge plates 22 in the discharge shells 29, 310 and 41 to move synchronously and reciprocally through the traction plate 21. The plate-shaped materials in the three discharge shells fall intermittently into the arc-shaped groove through the inclined platform 23 at their respective bottom ends, and cooperate with the basic parts, columnar materials and pins put in the early stage in sequence to complete the pre-selection assembly of each component of the entire chain. The conveying pipe 18 completes the feeding of plate-shaped materials three times for each rotation. The pre-assembled chain assembly is gradually conveyed forward along the transmission shaft 12 within the arc-shaped groove to directly below the stamping plate 3. The driving end of the stamping device 2 retracts, causing the L-shaped connecting frame to move downwards. The connecting frame then causes the stamping plate 3 to press downwards onto the chain surface, completing the extrusion stamping process for each component. Simultaneously, the rotation of transmission rod 13 drives transmission rod 2 14 to rotate synchronously via the transmission belt assembly at its bottom. The driving gear at the top of transmission rod 2 14 drives transmission rod 3 15 to rotate via a meshing driven gear. The transmission sprockets 17 on the two transmission rods 3 15 rotate relative to each other, driving the stamped chain to continue forward. The cam 328 at the top of the transmission rod 315 rotates synchronously with the transmission sprocket 17. The cam 328 drives the traction frame 30 to reciprocate linearly through the traction plate 329. The cover plate 31 at the end of the traction frame 30 slides back and forth on the top surface of the nozzle 32, so that the through hole above the nozzle 32 is intermittently open. The rust inhibitor is sent into the liquid storage chamber of the control housing 33 through the delivery pipe 18 and then sprayed out from the nozzle 32 to perform rust prevention treatment on the surface of the chain that passes through. The frequency of the reciprocating movement of the cover plate 31 is matched with the chain conveying speed to ensure that the through hole is just open when each chain link passes under the nozzle 32, so as to achieve quantitative and precise spraying.
