[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] Please refer to Figures 1-4 This embodiment provides a non-standard stepped pin assembly device 100, which includes a workbench 110, a feeding assembly 120, a stepped pin assembly assembly 130, a stepped pin rivet assembly 140, and a fixed-length cutting assembly 150.

[0033] The feeding assembly 120, the step pin assembly 130, the step pin riveting head assembly 140, and the fixed-length cutting assembly 150 are sequentially connected to the worktable 110 along a preset direction (as shown by arrow A in the figure). The feeding assembly 120 is used to convey step pins to the step pin assembly assembly 130, the step pin assembly assembly 130 is used to assemble the received step pins to the chain, the step pin riveting head assembly 140 is used to rivet the step pins assembled to the chain, and the fixed-length cutting assembly 150 is used to cut the chain.

[0034] Please refer to Figures 1-4 The working principle of the non-standard stepped pin assembly device 100 is as follows:

[0035] The non-standard stepped pin assembly device 100 is used to process chains. Its purpose is to replace stepped pins according to requirements. Specifically, the non-standard stepped pin assembly device 100 includes a workbench 110, a feeding assembly 120, a stepped pin assembly assembly 130, a stepped pin riveting assembly 140, and a fixed-length cutting assembly 150.

[0036] The feeding assembly 120, the step pin assembly 130, the step pin rivet assembly 140, and the fixed-length cutting assembly 150 are sequentially connected to the worktable 110 in a preset direction. Thus, when the chain to be processed moves relative to the worktable 110, it moves in a preset direction and can pass through the step pin assembly 130, the step pin rivet assembly 140, and the fixed-length cutting assembly 150 in sequence.

[0037] Furthermore, the feeding assembly 120 is used to convey the step pin to the step pin assembly assembly 130, the step pin assembly assembly 130 is used to assemble the received step pin to the chain, the step pin riveting assembly 140 is used to rivet the step pin assembled to the chain, and the fixed length cutting assembly 150 is used to cut the chain.

[0038] Thus, when the chain passes through the workbench 110 in the preset direction, the steps of step pin assembly, step pin riveting and chain length cutting can be performed in sequence. Moreover, the replacement of the step pin is based on the preset replacement requirements, and the replacement is carried out continuously or intermittently at the corresponding chain link that meets the design requirements.

[0039] Therefore, the non-standard stepped pin assembly device 100 has a simple structure. Since each component adopts a modular installation method, the parameters of each module can be adjusted according to the usage requirements, and the structure of each module can be easily replaced or maintained. Moreover, the overall structure is simple and convenient to operate, and it is easy to add corresponding positioning, identification and detection devices, which is conducive to improving the automation and intelligence of the equipment. In addition, it has a wide range of applicable processing. Therefore, the non-standard stepped pin assembly device 100 can improve the efficiency and flexibility of chain processing, and reduce the processing cost of the chain.

[0040] Further, please refer to Figures 1-4 In this embodiment, when configuring the aforementioned stepped pin assembly 130, stepped pin riveting head assembly 140, and fixed-length cutting assembly 150, the following structural configuration is adopted. Specifically, the stepped pin assembly 130 includes a pin-changing cylinder 131 and a pin-changing mold 132. Both the pin-changing cylinder 131 and the pin-changing mold 132 are connected to the worktable 110, and the pin-changing cylinder 131 is used to eject the standard pin of the chain in the pin-changing mold 132 and insert the stepped pin.

[0041] The stepped pin rivet assembly 140 includes a stepped pin rivet cylinder 141 and a stepped pin rivet mold 142; both the stepped pin rivet cylinder 141 and the stepped pin rivet mold 142 are connected to the workbench 110, and the stepped pin rivet cylinder 141 is used to rivet the stepped pins of the chain in the stepped pin rivet mold 142.

[0042] The fixed-length cutting assembly includes a cutting die 151 and a cutting cylinder 152; both the cutting die 151 and the cutting cylinder 152 are connected to the worktable 110, and the cutting cylinder 152 is used to cut the chain in the cutting die 151.

[0043] Therefore, through the above structural settings, based on the corresponding mold structure configuration, it can work in conjunction with the appropriate power cylinder, thereby improving the automation and intelligence of processing, and thus reducing the cost of manual operation in an automated and mechanized manner, thereby improving processing efficiency and reducing processing costs.

[0044] In addition, during the processing, in order to guide the chain to move in a preset direction relative to the worktable 110 and change its position relative to the aforementioned stepped pin assembly 130, stepped pin riveting head assembly 140 and fixed-length cutting assembly 150, the non-standard stepped pin assembly device 100 also includes a drive motor 161 and a feed sprocket 162. The drive motor 161 is connected to the worktable 110, and the feed sprocket 162 is rotatably connected to the worktable 110. The drive motor 161 is used to drive the feed sprocket 162 to rotate, so as to guide the chain to move in a preset direction relative to the worktable 110. It should be noted that, through the above structural arrangement, the chain can be guided to move at the positions of the corresponding step pin assembly 130, step pin rivet head assembly 140, and fixed-length cutting assembly 150. The movement positions are relatively continuous, that is, the step pin assembly 130, step pin rivet head assembly 140, and fixed-length cutting assembly 150 can process the chain at different positions, so that the processing steps at each position can be carried out continuously, thereby improving processing efficiency.

[0045] In order to improve its feeding efficiency, the feeding assembly 120 includes a stepped pin vibrating feeding plate 121 connected to the worktable 110.

[0046] Furthermore, when assembling the step pins, it is necessary to remove the standard pins from their original positions on the chain. Therefore, the non-standard step pin assembly device 100 also includes a material collection box 122. The material collection box 122 is connected to the workbench 110 and is located below the step pin assembly assembly 130. It is used to collect the standard pins exported from the step pin assembly assembly 130.

[0047] In addition, in order to apply oil to the position of the replacement step pin, the non-standard step pin assembly device 100 also includes a step pin oiling component 170. The step pin oiling component 170 is arranged in a preset direction between the step pin rivet head assembly 140 and the fixed length cutting assembly 150, and is used to apply oil to the step pin assembled on the chain.

[0048] To improve work efficiency, the workbench 110 is equipped with a material collection area 111 and a material discharge area 112. The material collection area 111 is used to place the chain, and the material discharge area 112 is used to place the chain passing through the fixed-length cutting assembly 150. The material collection area 111 and the material discharge area 112 can temporarily store materials, thereby facilitating loading and unloading and improving processing efficiency.

[0049] In addition, for standard pin rivet heads in the chain, the non-standard stepped pin assembly device 100 also includes a standard pin rivet head assembly 180. The standard pin rivet head assembly 180 is connected to the workbench 110 and is arranged along a preset direction on the side of the stepped pin assembly assembly 130 away from the stepped pin rivet head assembly 140. It should be noted that in this embodiment, it is arranged on the side of the stepped pin assembly assembly 130 away from the stepped pin rivet head assembly 140 so that the chain enters the workstation where the stepped pin rivet head assembly 140 is located after the standard pin rivet head is installed. In other embodiments of this utility model, the standard pin rivet head assembly 180 can also be arranged in other positions on the workbench 110.

[0050] Specifically, the standard pin rivet assembly 180 includes a standard pin rivet mold 181 and a standard pin shaft rivet cylinder 182; both the standard pin rivet mold 181 and the standard pin shaft rivet cylinder 182 are connected to the worktable 110, and the standard pin shaft rivet cylinder 182 is used to rivet the standard pins of the chain in the standard pin rivet mold 181.

[0051] Based on the above, please refer to Figures 1-4 The non-standard stepped pin assembly device 100 adopts an integrated process, realizing the production of processes such as pin cutting, chain riveting, pin replacement, post-pin riveting, and on-demand disassembly in an assembly line. Each station has a modular design, which makes it extremely easy to change specifications. Furthermore, a positioning device can be installed on the workbench 110 to facilitate the switching between different specifications.

[0052] The non-standard stepped pin assembly device 100 is divided into five stations: a standard pin riveting head assembly 180, a stepped pin assembly 130, a stepped pin riveting head assembly 140, a stepped pin oiling assembly 170, and a fixed-length cutting assembly 150. When the drive motor 161 drives the feed sprocket 162 to rotate, it guides the chain to move relative to the worktable 110 in a preset direction, passing through the aforementioned five stations in sequence. The five stations are: 1. Riveting the upper and lower parts of the standard pin shaft (skip if the pin needs to be replaced); 2. Stepped pin replacement; 3. Riveting the bottom surface of the stepped pin; 4. Oiling the stepped pin; 5. Fixed-length cutting.

[0053] Based on the above structure, it is easy to add positioning, identification and detection modules to each module to realize functions such as jamming and detection. Moreover, the feed tube of the feed assembly 120 has a sensor detection device to detect whether there is material. If the chain jams, the drive motor 161 will alarm. The drive motor 161 is a servo motor.

[0054] Furthermore, the stroke of the cylinders at each workstation is controlled by digital sensors, which facilitates parameter setting when changing specifications; the hydraulic pressure is controlled by servo valves to automatically adjust the pressure required for each specification, saving energy and extending the service life of hydraulic components.

[0055] The overall control system can be switched to manual single-step control mode via a touch screen control system. The shaft changing station can be set as a single-step function, allowing for manual feeding of small, uniquely shaped pins, while large-volume orders utilize a vibratory feeder for pin direction identification and automatic feeding. Additionally, a pin orientation selection system is added. The mold adopts an integrated structure, improving mold change time; the time to change between different molds is controlled within 20 minutes.

[0056] Please refer to Figures 1-4 The operation process of the non-standard stepped pin assembly device 100 is as follows:

[0057] Chain feeding: The servo motor drives the feed sprocket 162 to rotate and pull the chain. Then, at each station, short chain pins are riveted, stepped pins are replaced, and then disassembly and replacement are performed. Stepped pins are riveted and oiled. Standard pins are riveted at each station, one or two at a time. Stepped pin assembly; stepped pin riveting station; stepped pin oiling station; chain disassembly station.

[0058] Moreover, the overall control can be achieved through the human-machine interface, which allows for parameter adjustment, production information input, production instruction issuance, production scheduling, and other related information on-site or remotely. It can realize the assembly of stepped pins every N sections, section by section, and step pin assembly. The step pin assembly model is not limited to an even distribution cycle. It can assemble one step pin every 2 sections, one step pin every two sections, and then one step pin every 3 sections, and repeat the cycle; repeat two step pins, repeat two step pins every N sections, continuously assemble N sections every N sections, and repeat the cycle. It can also have functions such as orderly cycle of 3 different types of step pins for one product.

[0059] Therefore, the non-standard stepped pin assembly device 100 adopts an integrated structure, which can improve the mold change time. Moreover, the mold can be quickly switched and positioned according to the positioning device of the equipment, thereby realizing rapid specification switching. Each key station of the equipment can be equipped with mechanical detection or photoelectric detection to prevent mistakes. The front material collection table detection controls the presence of the base chain before assembly, displays the material shortage in the previous stage, and the equipment automatically stops. If the material is detected, the equipment will automatically start after a delay of 2-5 seconds. The post-assembly sensing detection controls the material collection table to stop when it is full. The stepped pin feeding detection detects whether there is material in the stepped pin feeding tube. If there is a material shortage, wait. If the presence or absence is detected, the equipment will automatically stop or start.

[0060] Post-assembly inspection of stepped pins controls assembly cycle errors such as omissions and overassemblies; inspection at the disassembly station uses a cyclical method to detect the position of long pins, preventing product defects and safety hazards.

[0061] In summary, based on the aforementioned non-standard stepped pin assembly device 100, this embodiment also provides a chain processing production line, which includes the aforementioned non-standard stepped pin assembly device 100.

[0062] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
