Description

Technical Field

[0001] This application relates to the field of chain twisting machine technology, and in particular to a dual-purpose chain twisting machine. Background Technology

[0002] Currently, large chain disassembly mainly relies on manual tools (such as chain wrenches and hammers), which are inefficient and easily damage the chain. In recent years, semi-automatic disassembly equipment has become increasingly common, but most of these devices use a single cylinder drive, which cannot simultaneously complete the chain lifting and rotation actions. They also struggle to adapt to the different chain clamping limitations, still requiring manual intervention to adjust the chain position. Existing equipment generally suffers from limited functionality, high operational complexity, and poor compatibility, failing to achieve continuous automation of the chain disassembly process. In response to the aforementioned existing technologies, the inventors believe that the industry urgently needs an automated disassembly solution integrating lifting and rotation functions to improve chain disassembly efficiency. Summary of the Invention

[0003] In order to integrate multiple functions to enable the disassembly and use of chains, this application provides a dual-purpose chain twisting machine.

[0004] This application provides a dual-purpose twist chain machine, which adopts the following technical solution: A dual-purpose chain twisting machine includes a first station, a second station, and an ejection assembly. The first station has a first limiting seat with a first chain buckle limiting groove and a first clamping assembly, including a first clamping plate extending into the first chain buckle limiting groove. The second station has a second limiting seat with a second chain buckle limiting groove and a second clamping assembly, including a second clamping plate extending into the second chain buckle limiting groove. The first and second limiting seats are arranged opposite to each other. The second station is connected to the ejection assembly and also to a twisting assembly. During operation, one end of the target chain buckle is placed in the first chain buckle limiting groove, the ejection assembly moves the second station to place the other end of the chain buckle in the second chain buckle limiting groove, and the twisting assembly rotates the second limiting seat to twist open the chain buckle connection.

[0005] By adopting the above technical solution, the first station is aligned with the second station. The first chain buckle limiting groove set on the first station and the second chain buckle limiting groove designed on the second station have the same structure and are designed opposite each other. By pushing the second station to move towards the first station through the ejection component, and with the independent clamping parts designed on the two sets of chain buckle limiting grooves extending in to clamp, a target chain buckle clamping limit can be established on the chain at the same time. The second limiting seat of the second station is controlled by the torsion component to change the setting angle of the second chain buckle limiting groove. By twisting the end of the chain buckle connected to the second chain buckle limiting groove, the target chain buckle can be removed from the chain.

[0006] Optionally, the first workstation includes a first support, a first fixing frame is provided on the first support, a connecting shaft is provided in the center of the first fixing frame, and the first limiting seat is provided on the connecting shaft.

[0007] By adopting the above technical solution, the first station is set on the machine frame by the first bracket, and the machine frame establishes the support and operating space between the first station and the second station, which facilitates the operation of the workers. The first bracket supports the installation of the first fixed frame and fixes the installation of the connecting shaft through the first fixed frame. One end of the connecting shaft is connected to the first limiting seat, and the first limiting seat is aligned with the second limiting seat.

[0008] Optionally, the connecting shaft connection is provided with a plug cavity, the plug cavity is a regular polygonal structure, and the corners of the plug cavity are respectively provided with arc-shaped slots.

[0009] By adopting the above technical solution, the mounting end of the connecting shaft is provided with a plug-in cavity to establish a plug-in connection with the connecting end of the first limiting seat, and multiple sets of arc-shaped slots are used to limit the installation stability of the connecting end of the first limiting seat, so as to avoid the first limiting seat from loosening due to the negative impact of the torque generated by the chain rotation.

[0010] Optionally, the first clamping assembly further includes two sets of adjusting gears, which are disposed on the first limiting seat and mesh with each other. Each adjusting gear has a set of screws inside it, and the threads on the two sets of screws are opposite. The first clamping plate has two sets of spiral grooves that are rotatably connected to the screws respectively.

[0011] By adopting the above technical solution, two sets of adjusting gears are set to mesh with each other. One set of adjusting gears is connected to a stepper motor. The stepper motor drives the two sets of adjusting gears to rotate relative to each other, thereby driving the two sets of screws to rotate in opposite directions. Since the threads on the two sets of screws are designed to be opposite, the first abutting plate that is helically connected to the two sets of screws can be driven to move stably, so as to establish or release the abutment against the chain buckle, ensuring the stability of the adjustment operation of the first limit seat on the chain buckle, and enabling the first limit seat to be adapted to the fixing of chain buckles of various specifications within a certain range.

[0012] Optionally, the second workstation further includes a rotating frame, on which a rotating block is provided, and on which two sets of snap-fit ​​sleeves are provided and movably connected, both sets of snap-fit ​​sleeves are connected to a vertical support, and a connecting pin is provided near the second limiting seat of the rotating frame, the connecting pin being inserted into the second limiting seat.

[0013] By adopting the above technical solution, the second station is connected to the second limit seat through the rotating frame and connecting pin, and is set on the vertical support through two sets of snap-fit ​​sleeves. The rotating frame can move axially and circumferentially within the snap-fit ​​sleeves without affecting the installation of the snap-fit ​​sleeves. The snap-fit ​​sleeves only serve as the connection structure between the vertical support and the rotating frame and rotating block, and do not restrict the movement and rotation of the rotating frame.

[0014] Optionally, the torsion assembly includes a rack, a push gear, and a second pusher. The push gear is disposed on the rotating block and connected to the rack, and the other end of the rack is connected to the second pusher.

[0015] By adopting the above technical solution, the torsion component pushes the rack to move through the second pusher, thereby acting on the push gear to generate circumferential displacement, thus changing the installation angle of the rotating frame connected to the push gear, thereby changing the setting angle of the second limit seat, and twisting the connection of the chain buckle to release the chain buckle connection; the center of the push gear is connected to the rotating frame through the rotating block, and the rotating block is fixedly connected to both the rotating frame and the push gear to ensure the accuracy of the circumferential displacement generated by the push gear on the rotating frame.

[0016] Optionally, the rack is disposed inside the push slider, and the push slider has a movable notch at the movable end of the rack.

[0017] By adopting the above technical solution, the second pusher drives the rack to reciprocate within the pusher slider, and the movable notch provides space for the installation and movement of the rack.

[0018] Optionally, the rotating frame has an abutment frame at one end away from the second limiting seat, a follower seat is provided on the abutment frame, a connecting groove is provided at the other end of the follower seat, and a counteracting bearing is provided in the connecting groove.

[0019] By adopting the above technical solution, the rotating frame establishes a connection with the follower seat through the abutment frame, and the follower seat is connected to the offset bearing through the connecting groove. That is, the torque generated by the torsion component driving the rotating frame through the push gear is eliminated by the offset bearing, which will not have a negative impact on the installation and use of the ejection component connected to the offset bearing, so that the ejection component can normally and efficiently drive the second limit seat to approach or move away from the first limit seat.

[0020] Optionally, the vertical support is further provided with two sets of gripping components, the gripping components including multi-axis mechanical components and robotic arms, the robotic arms including two sets of electromagnetic claw teeth.

[0021] By adopting the above technical solution, two sets of grippers are respectively set on both sides of the second work station. Two sets of independent robotic arms can pick up the two ends of the chain buckle and place them into the first chain buckle limiting groove and the second chain buckle limiting groove respectively, or remove the twisted chain buckle from the chain and then enter the next round of chain disassembly operation.

[0022] Optionally, the vertical support is further provided with a swing motor, the swing motor is provided with a rotating cam, and the rotating cam is provided with a telescopic lever.

[0023] By adopting the above technical solution, the swing motor controls the rotating cam to swing back and forth, and the telescopic wave rod installed on the rotating cam moves the chain placed on the placement frame toward the robot arm. In coordination with the robot arm, the chain is moved synchronously when the chain buckle is removed, so as to complete the continuous chain removal operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects: A dual-purpose chain twisting machine is provided, with a first station and a second station arranged opposite to each other. The first station is a stably connected component, and the second station is a retractable and rotatable component. A first clamping component on a first limiting seat is used to limit one end of the chain buckle. An ejecting component pushes a second limiting seat to the other end of the chain buckle and is limited by a second clamping component. A twisting component pushes the second limiting seat to rotate, twisting open the connecting end on the chain buckle and disconnecting the chain buckle from the chain. This application combines two working modes, lifting and rotation, to limit the chain buckle and unscrew it, which can reduce the violent point contact disassembly of the chain and realize continuous chain disassembly without damaging the chain buckle and the chain. In this application, the process of inserting the chain buckle into the first chain buckle limiting groove and the second chain buckle limiting groove can be completed manually by workers or by two sets of robotic arms set on the vertical support, which can realize fully automatic or semi-automatic operation to improve the adaptability of the chain twisting machine. The two sets of clamping parts in this application are set up and work on the same principle. The first limit seat and the second limit seat are each provided with two sets of meshing adjustment gears, and one set of adjustment gears is connected to a stepper motor. The screw connected to the adjustment gear is used to adjust the distance between the clamping plate and the chain buckle, so as to complete the clamping limit of the chain buckle. Then the twisting component can enter the twisting process. Both the ejection assembly and the torsion assembly of this application use a cylinder as a power source to drive the second limit seat and the rack to move. The second limit seat approaches the first limit seat to complete the limiting of the chain buckle, while the rack drives the push gear to produce circumferential displacement, which drives the second limit seat, which is in the assembled state with the chain buckle, to produce circumferential displacement synchronously. By twisting the chain buckle connection, the chain buckle can be removed from the chain. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0028] This application discloses a dual-purpose twist chain machine, referring to... Figure 1 and Figure 2 The system includes a first station 2, a second station 3, an ejector assembly 4, and a torsion assembly 5. The first station 2, the second station 3, the ejector assembly 4, and the torsion assembly 5 are all mounted on the frame 1, with the first station 2 and the second station 3 positioned opposite each other. The second station 3 is connected to the ejector assembly 4 and the torsion assembly 5. The ejector assembly 4 can move towards the first station 2 by acting on the second limit seat 31 mounted on the second station 3. The torsion assembly 5 can drive the second limit seat 31 to produce circumferential displacement. The frame 1 is equipped with a foot switch 8 on the operator's side. When the operator manually loads or unloads materials, the foot switch 8 is used to open the ejector assembly 4 and the torsion assembly 5.

[0029] In this application, the ejector component 4 and the torsion component 5 are controlled by the same switch signal. When the foot switch 8 is pressed for the first time, the ejector component 4 is opened. When the foot switch 8 is pressed again, the ejector component 4 does not move, and the torsion component 5 controls the second limit seat 31 to rotate. After the chain is unscrewed and removed, the ejector component 4 and the torsion component 5 are reset one after another. When the control signal is input, the next cycle begins.

[0030] This application provides a chain placement belt 7 on the frame 1 for temporarily placing the chain to be disassembled, and temporarily placing the disassembled chain buckle at the other end of the chain placement belt 7. A waste collection box is placed below this point to collect the disassembled chain buckle.

[0031] Reference Figures 3 to 5 The first station 2 includes a first support 21, on which a first fixing frame 22 is provided. A connecting shaft 23 is provided in the center of the first fixing frame 22. A plug-in cavity 231 is provided at the connection of the connecting shaft 23. The plug-in cavity 231 is a regular polygonal structure. Arc-shaped slots 232 are provided at the corners of the plug-in cavity 231. A first limiting seat 24 is provided with a plug-in post corresponding to the plug-in cavity 231. An arc-shaped plug-in frame is provided at the corresponding arc-shaped slot 232 of the plug-in post to fix the first limiting seat 24 on the connecting shaft 23 and ensure the stability of the first limiting seat 24. The first limiting seat 24 is a cylindrical structure and a first chain buckle limiting groove 241 is provided on its contact surface to limit the connection of the chain buckle. The first limiting seat 24 is provided with a first abutting assembly, which includes two sets of adjusting gears 25 and a first abutting plate 28. The two sets of adjusting gears 25 are disposed on the first limiting seat 24 and mesh with each other. Each adjusting gear 25 has a set of screws 27 inside it. The threads on the two sets of screws 27 are opposite and simultaneously rotate with two sets of spiral grooves on the first abutting plate 28. The first abutting plate 28 extends into the first chain buckle limiting groove 241. One set of adjusting gears 25 is connected to a stepper motor 26. The stepper motor 26 receives a control signal and drives the two sets of adjusting gears 25 to rotate relative to each other, thereby driving the adjustment assembly to rotate. The two sets of screws 27 rotate in opposite directions. Due to the opposite thread design on the two sets of screws 27, the first abutting plate 28, which is helically connected to the two sets of screws 27, can be driven to move steadily towards / away from the chain buckle to establish / release the abutment on the chain buckle, ensuring the stability of the adjustment operation of the chain buckle by the first limit seat 24. After the chain buckle is unscrewed, the stepper motor 26 rotates in the opposite direction, driving the two sets of screws 27 to control the first abutting plate 28 to move away from the chain buckle, so that the chain buckle can be removed from the first chain buckle limiting groove 241, so that the first limit seat 24 can be adapted to fix chain buckles of various specifications within a certain range.

[0032] Reference Figures 6 to 8 The second station 3 is provided with a second limiting seat 31, a second chain buckle limiting groove, and a second abutting component. The structure of the second abutting component is the same as that of the first abutting component. The second abutting component includes a second abutting plate and a screw, adjusting gear, and stepper motor connected to the second abutting plate. The second abutting plate extends into the second chain buckle limiting groove. The working process and principle are the same as those of the first abutting plate. The stepper motor connected to the second abutting plate adjusts its specific position in the second chain buckle limiting groove to establish a connection with the other end of the chain buckle or remove the limitation on the other end of the chain buckle. The first limiting seat 24 and the second limiting seat 31 are arranged opposite to each other. The first limiting seat 24 and the second limiting seat 31 simultaneously fix both ends of the target chain buckle. The second limiting seat 31 can also be adapted to fix chain buckles of various specifications.

[0033] The second workstation 3 also includes a rotating frame 32. The rotating frame 32 is provided with a connecting pin 321 near the second limiting seat 31. The connecting pin 321 is inserted into the second limiting seat 31. A fixing sleeve 33 is provided at the connection between the second limiting seat 31 and the connecting pin 321 to enhance the firmness of the connection between the connecting pin 321 and the second limiting seat 31, and to prevent the second limiting seat 31 from coming off the connecting pin 321 due to rotation or interaction with other structures.

[0034] A rotating block 34 is fitted on the rotating frame 32. In this embodiment, the rotating block 34 is a cylindrical body, and a regular polygonal structure is provided on the outer side of the middle end of the cylindrical body to connect with the inner diameter of the push gear 54. The edge structure of the regular polygon can effectively enhance the stability of the connection between the rotating block 34 and the push gear 54 and avoid the torsional error between the two. The rotating frame 32 establishes a connection with the torsion component 5 through the rotating block 34. The torsion component 5 drives the rotating block 34 to generate circumferential displacement. The rotating block 34 is provided with two sets of snap-fit ​​sleeves 35 and is movably connected to the snap-fit ​​sleeves 35. Both sets of snap-fit ​​sleeves 35 are connected to the vertical support 11. The vertical support 11 is a hollow shell, which provides working space for the rotating block 34 and its connecting parts. That is, when the twisting component 5 drives the rotating block 34 to generate circumferential displacement, and the second limit seat 31 is controlled to unscrew the chain buckle or reset, the snap-fit ​​sleeve 35 maintains its connection relationship with the vertical support 11 and does not follow the rotating block 34 to generate circumferential displacement, so as to ensure the stability of the vertical support 11 in supporting and limiting the entire second station 3.

[0035] The rotating frame 32 is provided with an abutment frame at one end away from the second limit seat 31. A follower seat 36 is provided on the abutment frame. The other end of the follower seat 36 is provided with a connecting groove. A counteracting bearing 37 is provided in the connecting groove. When the torsion component 5 drives the rotating frame 32 to generate circumferential displacement and generates torque on the chain buckle provided in the second limit seat 31, the torque at the other end of the rotating frame 32 acts on the counteracting bearing 37. It only affects the counteracting bearing 37, but does not affect the first push rod connected to the counteracting bearing 37 in any circumferential displacement. That is, no matter how the torsion component 5 generates torque on the rotating frame 32 in terms of direction and amplitude, it will not affect the ejection component 4's ejection control of the rotating frame 32.

[0036] The second limiting seat 31 is equipped with a distance sensor on its alignment panel. The control terminal can set a safe approach distance. When the distance sensor detects that the distance between the second limiting seat 31 and the first limiting seat 24 has reached a critical value, it will stop moving. This avoids the two sets of limiting seats from wirelessly approaching each other and causing safety accidents when there is no chain buckle in the first chain buckle limiting groove 241 and / or the second chain buckle limiting groove. This structure is mainly designed for safety during manual operation.

[0037] Both the first limiting seat 24 and the second limiting seat 31 are easy to assemble and disassemble with their connecting structures, thereby increasing the range of applications for the chain twisting machine and enabling it to adapt to chains of different specifications, thus improving the practicality of the chain twisting machine.

[0038] A first push mounting bracket 12 is provided on the frame 1 to establish the installation of the ejector assembly 4. The ejector assembly 4 is provided with a first pusher to push the rotating frame 32 to generate axial displacement. In this embodiment, the first pusher is a cylinder. The cylinder is provided with a first push rod connected to the inner ring of the offset bearing 37. The outer ring of the offset bearing 37 rotates with the follower seat 36, but it will not affect the connection relationship between the inner ring of the offset bearing 37 and the first push rod, thereby ensuring that the first pusher can generate axial displacement through the rotating frame 32 acting on the second limit seat 31.

[0039] A second push mounting bracket 13 is provided on the frame 1 to establish the installation of the torsion component 5. The torsion component 5 includes a rack 53, a push gear 54 and a second push member 51. A rotating block 34 is provided on the rotating frame 32. The push gear 54 is located on the rotating block 34 and meshes with the rack 53. The other end of the rack 53 is connected to the second push member 51. In this embodiment, the second push member 51 is a cylinder. The cylinder controls the second push rod 52 to push the rack 53 to move, thereby driving the push gear 54 to generate circumferential displacement, thereby driving the rotating block 34 and the rotating frame 32 to rotate at the same amplitude, realizing the torsion opening of the chain buckle by the second chain buckle limiting groove.

[0040] The rack 53 is located inside the push slider 14. The push slider 14 has movable notches at the movable ends of the rack 53. The second push rod 52 drives the rack 53 to slide back and forth inside the push slider 14, which can quickly control the working state of the push gear 54. The rack 53 moves at the movable notches, removing the restriction on the movement of the rack 53 by the frame structure of the push slider 14.

[0041] In other embodiments, the first pusher and the second pusher 51 can be configured as other structures that generate linear displacement, such as a combination of a hydraulic cylinder or a motor and a lead screw to generate linear output, which can drive the rotating frame 32 or the rack 53 to generate linear displacement; other gears and motor structures that mesh with the push gear 54 can also be provided on the push gear 54 to ensure that the push gear 54 generates circumferential displacement.

[0042] Reference Figure 1 and Figure 9The vertical support 11 is also equipped with two sets of gripping components 6, which are respectively located on both sides of the second workstation 3. The two sets of gripping components 6 have the same structure and each includes a multi-axis robotic arm 62 and a robotic hand. The multi-axis robotic arm 62 is fixedly installed on the vertical support 11 through a connecting seat 61. The robotic hand includes a rotating shaft 64, a gripping motor 66, and electromagnetic claw teeth 67. The rotating shaft 64 is connected to the multi-axis robotic arm 62. The other end of the rotating shaft 64 is equipped with a mounting seat. The mounting seat is equipped with two sets of gripping gears 65. The two sets of gripping gears 65 are respectively connected to a set of electromagnetic claw teeth 67. The other side of one set of electromagnetic claw teeth 67 is connected to the gripping motor 66. When the gripping motor 66 receives a gripping command, it drives the gripping gear 65 connected to it to rotate. The other set of gripping gears 65 rotates relative to or away from this set of gripping gears 65, so as to drive the two sets of electromagnetic claw teeth 67 to run relative to or away from each other, so as to pick up or put down the chain buckle. The electromagnetic claw teeth 67 are designed with an electromagnet structure. When energized during chain buckle retrieval, they become magnetic. After the gripping motor 66 receives a working signal and rotates in the reverse direction, the power supply to the electromagnetic claw teeth 67 is disconnected, and its magnetic force disappears, allowing the chain buckle to be quickly lowered. Rubber gripping teeth 68 are also provided on both sides of the electromagnetic claw teeth 67, which can increase the contact area and friction between the robotic arm and the chain buckle, improve the gripping stability, and prevent the robotic claw from causing wear on the chain buckle. The multi-axis robotic arm 62 and the robotic hand are equipped with a steering motor 63, which works with the multi-axis robotic arm to control the movement of the robotic hand in space. The two sets of independent robotic hands place the two ends of the chain buckle into the first chain buckle limiting groove 241 and the second chain buckle limiting groove, respectively, or remove the twisted chain buckle from the chain before proceeding to the next round of chain dismantling operations.

[0043] The vertical support 11 is also equipped with a swing motor 112, a rotating cam 113, and a telescopic lever 114. The swing motor 112 drives the rotating cam 113 to swing back and forth, which in turn drives the telescopic lever 114 to push the chain from the chain placement belt 7 to the side of the gripper 6, so that the robotic arm of the gripper 6 can pick up the chain buckle and perform disassembly.

[0044] The vertical support 11 is also equipped with a camera 111, which can capture images in real time to work with the swing motor 112 and the gripper 6 to improve the accuracy of automated operations.

[0045] The implementation principle of a dual-purpose chain twisting machine according to an embodiment of this application is as follows: The chain to be disassembled is placed on the chain placement belt 7. If the disassembly is done manually by the worker, one end of the chain buckle is inserted into the first chain buckle limiting groove 241. The first clamping member controls the first clamping plate 28 to move down and fix the chain buckle. The foot switch 8 is pressed, and the cylinder in the ejector assembly 4 pushes out the second limiting seat 31. The other end of the target chain buckle is inserted into the second chain buckle limiting groove. The second clamping member controls the second clamping plate to move down and fix the chain buckle. The foot switch 8 is pressed again, and the cylinder in the twisting assembly 5 pushes out the spur rack 53, which drives the push gear 54 to rotate. The rotating block 34 rotates in sync with the push gear 54, which can drive the second limiting seat 31 to twist open the chain buckle connection, and the chain buckle can be removed from the chain. Repeating the operation can complete the disassembly and reassembly of the chain multiple times. If the chain twisting machine is used independently, press the switch set on the vertical support 11. The control end will start the two sets of gripping parts 6 and the telescopic lever 114 to start the operation. The chain placed on the chain placement belt 7 will be moved segment by segment between the first station 2 and the second station 3. The other two sets of mechanical claws, with the assistance of the camera 111, will grab the target chain buckle into the first chain buckle limiting groove 241 and the second chain buckle limiting groove. Then, the twisting component 5 will control the second limiting seat 31 to rotate, unscrew the chain buckle and remove it by the corresponding mechanical claw, and then start the new chain dismantling operation.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
