[0002] In modern industrial production, chain plate assemblies, as key components of mechanical transmission systems, are widely used in automated production lines, logistics conveying equipment, construction machinery, and many other industries. Their assembly quality and efficiency directly affect the overall performance and production benefits of the equipment.

[0003] like Figure 8 As shown, the current assembly process for the first, second, and third chain plates is as follows: First, a set of bolts is inserted through the first mounting hole in the second chain plate and then threaded into the first screw hole in the first chain plate. After completing the above steps, another set of bolts is inserted through the second mounting hole in the third chain plate and threaded into the second screw hole in the second chain plate. However, in actual production, this assembly process mainly relies on manual assembly. Workers need to use hand tools to insert, align, and tighten the bolts one by one. This not only consumes a lot of labor costs, but also has limited speed, making it difficult to meet the needs of large-scale, high-efficiency modern production.

[0004] Therefore, we propose a chain-disc screw locking device. Utility Model Content

[0043] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0044] Please refer to Figures 1 to 8As shown, an embodiment of this utility model provides a chain-driven screw-locking device, including a base 1. A rotating disk 2 and a screw-locking assembly 4 are respectively arranged on the top of the base 1. A motor is fixedly installed inside the base 1, and the rotating shaft of the motor is fixedly connected to the bottom of the rotating disk 2. Multiple sets of tooling assemblies 3 are arranged on the rotating disk 2. The tooling assemblies 3 are used to stack the first chain plate 8, the second chain plate 9, and the third chain plate 10 to be assembled. The screw-locking assembly 4 includes a first support base 401, which is fixedly installed on the top of the base 1. A first top seat 402 is fixedly installed on the top of the first support base 401. A first electric push rod 403 is fixedly installed on the top of the first top seat 402. A first movable seat 404 is slidably arranged on the first support base 401. The bottom of the piston rod of the first electric push rod 403 slides through the first top seat 402 and is fixedly connected to the top of the first movable seat 404. Multiple sets of screw-locking machines 405 are fixedly installed on the first movable seat 404.

[0045] Working principle: After the motor in the base 1 starts, it drives the rotating shaft to rotate, which in turn drives the rotating disk 2 to rotate, causing the tooling assembly 3 on the rotating disk 2 to move to the screw fastening assembly 4. Then, the first electric push rod 403, through the extension of the piston rod, drives the first movable seat 404 to move downward, and the screw fastening machine 405 on the first movable seat 404 descends, completing the screw fastening work.

[0046] In this embodiment, the tooling assembly 3 includes an assembly base 301, which is fixedly mounted on the rotary disk 2. A groove 303 is formed on the top of the assembly base 301, and a guide assembly is disposed within the groove 303. The guide assembly includes a movable plate 305, which is slidably disposed within the groove 303. A first spring 304 is disposed inside the groove 303, with its top abutting against the bottom of the movable plate 305 and its bottom pressing against the bottom of the groove 303. A first movable limiting rod 307 and a second movable limiting rod 306 are fixedly connected to the movable plate 305. The upper end of the first chain plate 8 can pass through the first screw hole 802 on the first chain plate 8 and then exit through the first mounting hole 901 on the second chain plate 9. The upper end of the second movable limiting rod 306 can pass through the second screw hole 902 on the second chain plate 9 and then exit through the second mounting hole 1001 on the third chain plate 10. The top of the assembly base 301 is fixedly installed with a fixed limiting rod 302, and the first chain plate 8 is sleeved on the fixed limiting rod 302 through the connecting screw hole 801. The bottom of the first movable base 404 is fixedly connected with a pressure rod 406, which can pass through the middle of the first chain plate 8, the second chain plate 9 and the third chain plate 10 to press down on the movable plate 305.

[0047] During chain plate assembly, the first chain plate 8 is first positioned by fitting it onto the fixed limiting rod 302 through the connecting screw hole 801, thus limiting the position of the first chain plate 8. Then, the second chain plate 9 and the third chain plate 10 are positioned by the first movable limiting rod 307 and the second movable limiting rod 306, respectively. During screw tightening, the first movable seat 404 descends, the pressure rod 406 presses down on the movable plate 305, and the movable plate 305 compresses the first spring 304 and slides downward, causing the first movable limiting rod 307 and the second movable limiting rod 306 to move downward, making room for screw installation.

[0048] By using the guide components, the first chain plate 8, the second chain plate 9, and the third chain plate 10 can be limited during the rotation of the tooling assembly 3, thus preventing misalignment.

[0049] Furthermore, the bottom of the fixed limiting rod 302 presses against the top of the movable plate 305. This arrangement effectively prevents the movable plate 305 from detaching from the groove 303. It should be noted that a portion of the bottom of the fixed limiting rod 302 is fixed to the assembly base 301, while the other portion is positioned above the groove 303, thus allowing the bottom of the fixed limiting rod 302 to press against the top of the movable plate 305.

[0050] In this embodiment, a detection component 5 is also included. The detection component 5 includes a second support base 501, which is fixedly mounted on the base 1. A second top seat 502 is fixedly mounted on the top of the second support base 501, and a second electric push rod 503 is fixedly mounted on the top of the second top seat 502. A second movable seat 504 is slidably disposed on the second support base 501. The bottom of the piston rod of the second electric push rod 503 slides through the second top seat 502 and is fixedly connected to the top of the second movable seat 504. Multiple sets of detection rods 505 are disposed on the second movable seat 504. Each detection rod 505 includes a sleeve 5051, which is fixedly mounted on the second movable seat 504. The sleeve 5051 has a sliding groove 5057 inside, and a limit block 5053 is slidably arranged inside the sliding groove 5057. A movable rod 5052 is fixedly connected to the bottom of the limit block 5053. The lower end of the movable rod 5052 slides out from the bottom of the sleeve 5051. A pressure sensor 5054 is fixedly installed on the top of the sleeve 5051. A pressing block 5055 is slidably arranged inside the sliding groove 5057. A second spring 5056 is arranged between the pressing block 5055 and the limit block 5053. The top of the second spring 5056 abuts against the bottom of the pressing block 5055, and the bottom of the second spring 5056 presses against the top of the limit block 5053. The top of the pressing block 5055 abuts against the bottom of the pressure sensor 5054.

[0051] In use, the second electric push rod 503 drives the second movable seat 504 to descend, causing the detection rod 505 to contact the assembled chain plate assembly. When the movable rod 5052 presses against the bolt on the chain plate, the movable rod 5052 moves upward under force, pushing the limit block 5053 to compress the second spring 5056. The pressing block 5055 moves accordingly and presses the pressure sensor 5054. The pressure sensor 5054 converts the pressure signal into an electrical signal and outputs it to the controller inside the base 1. When the detected pressure exceeds the set threshold, it is determined that the screw is not tightened properly and has a protrusion problem. When the detected pressure is lower than the set threshold, it is determined that the screw is not properly locked at that position.

[0052] The pressure sensor 5054 involved in this embodiment can be a PT5300 pressure sensor.

[0053] In this embodiment, a feeding component 6 is also included. The feeding component 6 includes a third support base 601, which is fixedly installed on the machine base 1. A transverse linear module 602 is fixedly installed on the upper end of the third support base 601. A lifting cylinder 603 is fixedly installed on the slide of the transverse linear module 602. A pneumatic gripper 604 is fixedly installed at the bottom of the piston rod of the lifting cylinder 603.

[0054] In use, after the chain plate assembly is assembled and inspected, the horizontal linear module 602 drives the lifting cylinder 603 and the pneumatic gripper 604 to move above the chain plate assembly. The lifting cylinder 603 descends to make the pneumatic gripper 604 clamp the chain plate assembly. Then the lifting cylinder 603 rises, and the horizontal linear module 602 moves the chain plate assembly to the unloading position. The pneumatic gripper 604 releases, completing the unloading action.

[0055] Furthermore, a feeding guide plate 7 is fixedly installed on the base 1, and the feeding guide plate 7 is located below the lifting cylinder 603.

[0056] After the pneumatic gripper 604 releases the chain plate assembly, the chain plate assembly slides down along the unloading guide plate 7 to the designated position, ensuring the stability and accuracy of the unloading process.

[0057] Working principle

[0058] First, the first chain plate 8 to be assembled is fitted onto the fixed limiting rod 302 of the tooling assembly 3 through the connecting screw hole 801. The second chain plate 9 and the third chain plate 10 are positioned by the first movable limiting rod 307 and the second movable limiting rod 306, respectively. At this time, the first spring 304 is in its natural state, providing initial support for the chain plates. The motor in the machine base 1 drives the rotating disk 2 to rotate, transporting the tooling assembly 3 and the chain plates to the screw-locking station.

[0059] At the screw fastening station, the first electric push rod 403 of the screw fastening assembly 4 drives the first movable seat 404 to descend, and the pressure rod 406 presses down on the movable plate 305, causing the first movable limit rod 307 and the second movable limit rod 306 to move downward. At the same time, the screw fastening machine 405 descends to fasten the screws onto the chain plate. After the screw fastening is completed, the first movable seat 404 rises to reset.

[0060] The rotary table 2 continues to rotate, transporting the assembled chain plate assembly to the inspection station. The second electric push rod 503 of the inspection component 5 drives the second movable seat 504 to descend. The inspection rod 505 contacts the chain plate assembly for quality inspection. When the movable rod 5052 presses against the bolt on the chain plate, the movable rod 5052 moves upward under force, pushing the limit block 5053 to compress the second spring 5056. The pressing block 5055 moves accordingly and presses the pressure sensor 5054. The pressure sensor 5054 converts the pressure signal into an electrical signal and outputs it to the controller in the machine base 1. When the detected pressure exceeds the set threshold, it is determined that the screw has a protrusion problem of not being tightened properly. When the detected pressure is lower than the set threshold, it is determined that the screw is missing at that position.

[0061] The rotary table 2 continues to rotate, moving the inspected chain plate assembly to the unloading assembly 6. The horizontal linear module 602 of the unloading assembly 6 drives the lifting cylinder 603 and the pneumatic gripper 604 to move above the chain plate assembly. The lifting cylinder 603 descends, and the pneumatic gripper 604 clamps the chain plate assembly. Then the lifting cylinder 603 rises, and the horizontal linear module 602 moves the chain plate assembly above the unloading guide plate 7. The pneumatic gripper 604 releases, and the chain plate assembly slides down the unloading guide plate 7 to the designated position, completing the entire assembly, inspection, and unloading process of the chain plate assembly.
