Description

Technical Field

[0001] This invention belongs to the field of clamp processing technology, and more specifically, relates to an automatic assembly device for wire clamps. Background Technology

[0002] Guy wire clamps are key hardware used in power lines to secure guy wires to poles. They are mainly used on branch poles, corner poles, and terminal poles where additional stress is required. By connecting the guy wire to the pole, they enhance the stability of the line. A guy wire clamp consists of two semi-circular clamp plates, two bolts and nuts for connecting the clamp plates, and radially extending flanges at both ends of the clamp plates, with through holes for the bolts to pass through.

[0003] Guy wire clamps are typically sold as complete sets. Therefore, before leaving the factory, workers need to stack two clamp plates together and connect them with two bolts and nuts to form a complete product. Currently, the industry generally assembles guy wire clamps manually, which is labor-intensive and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic assembly device for wire clamps, which aims to improve the assembly efficiency of wire clamps.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an automatic assembly device for cable clamps, comprising: The workbench has a first station for placing two nuts, a second station for placing two bolts, and a third station for placing two stacked hoop plates; the third station is located between the first station and the second station; and An assembly table is slidably disposed between the second work station and the third work station via a driving component; the assembly table has two rotatable assembly parts, each of which corresponds to one of the two bolts located at the second work station, and the assembly parts have magnetism to attract the bolts, and the assembly parts are used to pick up the bolts located at the second work station; When the assembly table moves from the second station to the third station, the bolt passes through the through hole in the hoop and abuts against the nut at the first station. The assembly part drives the bolt to rotate and connects with the nut by thread.

[0006] In one possible implementation, two inclined first slides are fixed on the worktable, and multiple nuts are placed in each first slide in sequence. The top end of each first slide is open and the bottom end is closed. The bottom end of the two first slides is the first work station. Each of the first slides has a first notch at its bottom end. The first notch allows the shank of the bolt to pass laterally through the first slide and allows the shank of the bolt and the nut to move vertically out of the first slide. A limiting mechanism is provided at each of the first notches, and the limiting mechanism is used to fix the nut located at the first work station.

[0007] In one possible implementation, the limiting mechanism includes: A limiting part is slidably disposed at the first notch to close the first notch; when the limiting part closes the first notch, the limiting part abuts against the nut at the first work station to restrict the rotation of the nut; A triggering part is slidably disposed on the worktable; the triggering part has an elastic degree of freedom to extend toward the assembly table, and the triggering part is connected to the limiting part through a first linkage component; When the assembly table moves from the second station to the third station, the assembly table pushes the trigger part to move, and the first linkage component drives the limiting part to extend toward the first notch so that the limiting part abuts against the nut located at the first station and restricts the rotation of the nut.

[0008] In one possible implementation, two vertically arranged second slides are fixed on the workbench, and multiple bolts are placed sequentially in each second slide. The top and bottom of each second slide are open, and the bottom of the two second slides is the second work station. Each of the second slides is equipped with a material dropping mechanism at its bottom end, which is used to control the falling of the bolt located at the second work station.

[0009] In one possible implementation, the bolt located at the second station is defined as a pre-assembled part, and the bolt located above the pre-assembled part is a waiting part; the unloading mechanism includes: A support portion is horizontally slidably disposed on the second slide rail and located above the pre-assembled component. The support portion is used to restrict the waiting component from falling to the second work station. A blocking part is horizontally slidably disposed on the second slide rail and located below the pre-assembled part. The blocking part is used to restrict the falling of the pre-assembled part. The blocking part has an elastic degree of freedom to extend toward the assembly table. The blocking part is connected to the support part through a second linkage component. When the assembly platform moves from the third station to the second station, the assembly platform pushes the blocking part to move and open the bottom end of the second slide, so that the pre-assembled part falls to the assembly part, and the second linkage component drives the support part to extend towards the second slide, so that the support part supports the underside of the waiting part.

[0010] In one possible implementation, the blocking part has a first position, a second position, and a third position; In the first position, the blocking part closes the bottom of the second slide, and the supporting part avoids the bolt in the second slide; In the second position, the blocking part closes the bottom of the second slide, the supporting part extends into the second slide and supports the underside of the waiting component; In the third position, the blocking part opens the bottom of the second slide, the supporting part extends into the second slide, and supports the underside of the waiting component.

[0011] In one possible implementation, the assembly part includes: A rotating component is rotatably mounted on the assembly table; The pickup component is laterally slidably disposed on the rotating component. The pickup component has an elastic degree of freedom to move toward the first work station and also has a magnetic property to attract the bolt. The pickup component is used to pick up the bolt located at the second work station. The motor is fixedly mounted on the assembly platform, and its output end is connected to the rotating component.

[0012] In one possible implementation, the rotating component has a material discharge groove; the picking component has a groove that matches the head of the bolt, and the groove has a second notch in the vertical direction; When the assembly table moves to the point where the material drop chute connects with the corresponding second slide, the pre-assembled part sequentially passes through the material drop chute and the second notch into the slot.

[0013] In one possible implementation, the assembly part further includes two positioning parts located on both sides of the groove. The positioning parts have an elastic degree of freedom to rotate into the groove. The positioning parts abut against the head of the bolt located in the groove to keep the shank of the bolt horizontal. A gap is formed between the two positioning parts for the shank of the bolt to extend out.

[0014] In one possible implementation, the workbench has a receiving slot for stacking the two hoop plates, the receiving slot being located at the third work station.

[0015] The present invention provides an automatic assembly device for guy wire clamps. Compared with the prior art, the advantages are as follows: Traditional manual assembly requires workers to manually align the through holes of the two clamp plates, insert bolts one by one, and tighten nuts, which is tedious and repetitive, resulting in high labor intensity. This device achieves efficient assembly of guy wire clamps through the division of workstations on the workbench and the automated operation of the assembly table. The fixed positional relationship of the first, second, and third workstations ensures that the central axes of the bolts, clamp plates, and nuts are collinear, guaranteeing that there is no deviation during the bolt insertion process.

[0016] After the workers place the two stacked hoop plates at the third station, the assembly department picks up the bolt from the second station. The drive unit moves the assembly table from the second station to the third station. During this movement, the bolt carried by the assembly department is precisely aligned with the through hole of the hoop plate's wing and passes through it. Then, it continues to move until it abuts against the nut at the first station. At this point, the assembly department drives the bolt to rotate, completing the threaded connection with the nut and assembling the two hoop plates.

[0017] The entire process requires no manual intervention for bolt insertion and tightening, integrating traditional multi-step manual operations into an automated process, significantly reducing the labor intensity of workers and improving the efficiency of wire clamp assembly, making it particularly suitable for mass production scenarios.

[0021] To make the technical problem to be solved, the technical solution and the beneficial effects of the present invention clearer, the following description is provided in conjunction with the appendix. Figures 1 to 9 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The present invention will now describe an automatic assembly device for guy wire clamps. An automatic assembly device for guy wire clamps includes a workbench 1 and an assembly table 2.

[0023] The workbench 1 has a first station 1a for placing two nuts, a second station 2a for placing two bolts, and a third station 3a for placing two stacked hoop plates. The third station 3a is located between the first station 1a and the second station 2a.

[0024] Assembly table 2 is slidably positioned between second station 2a and third station 3a via drive component 3. Assembly table 2 has two rotatable assembly parts 21, each corresponding to one of the two bolts located at second station 2a. Assembly parts 21 have magnetism to attract bolts and are used to pick up bolts located at second station 2a.

[0025] When the assembly table 2 moves from the second station 2a to the third station 3a, the bolt passes through the through hole on the hoop and abuts against the nut at the first station 1a. The assembly part 21 drives the bolt to rotate and connects with the nut threadedly.

[0026] Specifically, the driving component 3 can be an electric cylinder, hydraulic cylinder, or pneumatic cylinder, etc.

[0027] The first station 1a, the second station 2a, and the third station 3a are arranged in a straight line, with the third station 3a in the center. This ensures that after the bolt is picked up from the second station 2a, it can pass through the through hole of the hoop plate in the third station 3a in a straight line and accurately align with the nut at the first station 1a. When the assembly table 2 moves to the second station 2a under the drive of the drive unit 3, the assembly part 21 magnetically attracts the bolt. During the movement to the third station 3a, the shank of the bolt automatically passes through the through hole of the hoop plate and abuts against the nut at the first station 1a. Then, the assembly part 21 drives the bolt to rotate, realizing the threaded connection between the bolt and the nut.

[0028] Traditional manual assembly requires workers to manually align the through holes of the two clamp plates, insert bolts one by one, and tighten nuts. This process is tedious, repetitive, and labor-intensive. This device achieves efficient assembly of the wire clamp through the division of workstations on workbench 1 and the automated operation of assembly table 2. The fixed positional relationship of the first workstation 1a, the second workstation 2a, and the third workstation 3a ensures that the central axes of the bolts, clamp plates, and nuts are collinear, guaranteeing that there is no deviation during the bolt insertion process.

[0029] After the workers place the two stacked hoop plates at the third station 3a, the assembly unit 21 picks up the bolt from the second station 2a. The drive unit 3 drives the assembly table 2 to move from the second station 2a to the third station 3a. During this process, the bolt carried by the assembly unit 21 is precisely aligned with the through hole of the hoop plate wing and passes through it. Then, it continues to move until it abuts against the nut at the first station 1a. At this point, the assembly unit 21 drives the bolt to rotate, completing the threaded connection with the nut and assembling the two hoop plates.

[0030] The entire process requires no manual intervention for bolt insertion and tightening, integrating traditional multi-step manual operations into an automated process, significantly reducing the labor intensity of workers and improving the efficiency of wire clamp assembly, making it particularly suitable for mass production scenarios.

[0031] In some embodiments, see Figure 3 , Figure 4 and Figure 5 Two inclined first slides 41 are fixed on the workbench 1. Multiple nuts are placed in each first slide 41 in sequence. The top of each first slide 41 is open and the bottom is closed. The bottom position of the two first slides 41 is the first station 1a.

[0032] Each first slide rail 41 has a first notch 411 at its bottom end. The first notch 411 allows the bolt shank to pass laterally through the first slide rail 41 and allows the bolt shank and nut to move vertically out of the first slide rail 41. Each first notch 411 is provided with a limit mechanism, which is used to fix the nut located at the first station 1a.

[0033] The inclined first slide 41 utilizes gravity to automatically slide the nut down, and the top opening can continuously replenish the nut, ensuring that the first station 1a at the bottom always has one nut to be assembled. Once a set of clamps is assembled and removed, the next nut in the first slide 41 immediately slides down to the first station 1a, forming a continuous feeding mode, eliminating the step of manually placing the nuts one by one, and improving the feeding efficiency.

[0034] The first notch 411 allows the bolt shank to pass laterally through the first slide rail 41 to engage with the internal nut, while also providing a vertical exit channel for the assembled bolt and nut. A limiting mechanism is used to fix the nut at the first station 1a, preventing the nut from rotating along with the bolt, ensuring smooth thread engagement. When the bolt shank passes through the first notch 411 and engages with the nut, the limiting mechanism firmly fixes the nut, and only axial feed occurs when the bolt rotates, resulting in a stable and jam-free threaded connection process.

[0035] In some embodiments, see Figure 5 and Figure 6 The limiting mechanism includes a limiting part 412 and a trigger part 413. The limiting part 412 is slidably disposed at the first notch 411 to close the first notch 411. When the limiting part 412 closes the first notch 411, it abuts against the nut at the first workstation 1a to restrict the nut's rotation. The trigger part 413 is slidably disposed on the worktable 1. The trigger part 413 has an elastic degree of freedom to extend towards the assembly table 2, and is connected to the limiting part 412 via a first linkage assembly.

[0036] When the assembly table 2 moves from the second station 2a to the third station 3a, the assembly table 2 pushes the trigger part 413 to move, and the first linkage component drives the limiting part 412 to extend toward the first notch 411 so that the limiting part 412 abuts against the nut located at the first station 1a and restricts the rotation of the nut.

[0037] When the assembly table 2 moves to the third station 3a, the trigger part 413 is pushed simultaneously, which drives the limiting part 412 to close the first notch 411 and press against the nut through the first linkage component. The limiting part 412 fits tightly against the side of the nut, restricting its rotation and preventing the nut from rotating along with the bolt, thus ensuring that the thread is smoothly engaged.

[0038] The elastic degree of freedom of the trigger part 413 allows it to automatically reset after the assembly table 2 leaves, driving the limiting part 412 to open the first notch 411, so that the assembled bolts and nuts can be removed.

[0039] For details, please see Figure 2 , Figure 4 and Figure 6 The worktable 1 has two first bases 11, each corresponding to a first slide rail 41. The first linkage assembly includes a first gear 111, a first rack 112, and a second rack 113. The first gear 111 is rotatably mounted on the first base 11. The first rack 112 is fixedly mounted on the limiting part 412 and meshes with the first gear 111. The second rack 113 is fixedly mounted on the trigger part 413 and meshes with the first gear 111. Both the first rack 112 and the second rack 113 are slidably connected to the first base 11. The first rack 112 and the second rack 113 are located on the upper and lower sides of the first gear 111, respectively.

[0040] For details, please see Figure 6 A first spring 114 is fixedly disposed between the second rack 113 and the first base 11, and the trigger part 413 is moved by the first spring 114.

[0041] In some embodiments, see Figure 1 and Figure 3 Two vertically arranged second slide rails 42 are fixed on the workbench 1. Multiple bolts are placed sequentially in each second slide rail 42. The top and bottom of each second slide rail 42 are open. The bottom of the two second slide rails 42 is located at the second station 2a. A material dropping mechanism is provided at the bottom of each second slide rail 42. The material dropping mechanism is used to control the bolts located at the second station 2a to fall.

[0042] The bolts stacked within the vertically arranged second slide rail 42 fall under their own weight, ensuring that there is always one bolt available for pickup at the bottom second workstation 2a. The second slide rail 42 can accommodate multiple bolts, allowing for continuous production with only one replenishment, reducing the frequency of resupply. Through the coordinated movement of the unloading mechanism and the assembly table 2, when the assembly section 21 moves below the second workstation 2a, the unloading mechanism releases the bolts from the second workstation 2a into the assembly section 21.

[0043] In some embodiments, see Figure 4 and Figure 7The bolt located at the second station 2a is defined as a pre-assembled part, and the bolt above the pre-assembled part is defined as a waiting part. The unloading mechanism includes a support part 421 and a blocking part 422. The support part 421 is horizontally slidably disposed on the second slide rail 42 and located above the pre-assembled part, and the support part 421 is used to restrict the waiting part from falling to the second station 2a. The blocking part 422 is horizontally slidably disposed on the second slide rail 42 and located below the pre-assembled part, and the blocking part 422 is used to restrict the pre-assembled part from falling. The blocking part 422 has an elastic degree of freedom to extend toward the assembly table 2, and the blocking part 422 is connected to the support part 421 through a second linkage assembly.

[0044] When the assembly table 2 moves from the third station 3a to the second station 2a, the assembly table 2 pushes the blocking part 422 to move and open the bottom end of the second slide rail 42 so that the pre-assembled part falls to the assembly part 21. The second linkage component drives the support part 421 to extend towards the second slide rail 42 so that the support part 421 supports the bottom of the waiting part.

[0045] When the assembly table 2 moves to the second workstation 2a, the pushing blocking part 422 opens the bottom end of the second slide rail 42, allowing the pre-assembled part to fall into the assembly part 21. At the same time, the support part 421 extends into the second slide rail 42 to support the waiting part, preventing it from falling with the pre-assembled part. This ensures that only one bolt is released into the assembly part 21 at a time, avoiding the stacking and jamming caused by multiple bolts falling at the same time, and ensuring that the assembly part 21 picks up only one bolt at a time.

[0046] The elastic freedom of the blocking part 422 allows it to automatically reset after the assembly table 2 leaves, sealing the bottom end of the second slide 42. At this time, the support part 421 retracts simultaneously, causing a waiting part to fall to the second station 2a to become a new pre-assembled part.

[0047] For details, please see Figure 4 and Figure 8 The worktable 1 has two second bases 12, each corresponding to a second slide rail 42. The second linkage assembly includes a second gear 121, a third rack 122, and a fourth rack 123. The second gear 121 is rotatably mounted on the second base 12. The third rack 122 is fixedly mounted on the support 421 and meshes with the second gear 121. The fourth rack 123 is fixedly mounted on the blocking part 422 and meshes with the second gear 121. Both the third rack 122 and the fourth rack 123 are slidably connected to the second base 12. The third rack 122 and the fourth rack 123 are located on the upper and lower sides of the second gear 121, respectively.

[0048] For details, please see Figure 8 A second spring 124 is fixedly disposed between the fourth rack 123 and the second base 12, and the second spring 124 pushes the blocking part 422 to move.

[0049] In some embodiments, the blocking portion 422 has a first position, a second position, and a third position. In the first position, the blocking portion 422 closes the bottom of the second slide rail 42, and the support portion 421 avoids the bolt within the second slide rail 42. In the second position, the blocking portion 422 closes the bottom of the second slide rail 42, and the support portion 421 extends into the second slide rail 42 and supports the underside of the mounting component. In the third position, the blocking portion 422 opens the bottom of the second slide rail 42, and the support portion 421 extends into the second slide rail 42 and supports the underside of the mounting component.

[0050] After the assembly unit 21 picks up the pre-assembled part, the assembly table 2 moves towards the third station 3a and separates from the blocking part 422. At this time, the blocking part 422 is in the first position, and the blocking part 422 closes the bottom end of the second slide rail 42. The support part 421 is pulled out from the second slide rail 42, thereby avoiding the bolts in the second slide rail 42, so that the waiting part falls to the second station 2a and becomes a new pre-assembled part, realizing the replenishment of the bolts at the second station 2a.

[0051] Assembly table 2 moves toward the second work station 2a and pushes the blocking part 422 to move. When the blocking part 422 moves to the second position, the blocking part 422 still keeps the second slide rail 42 closed, while the support part 421 extends into the second slide rail 42 under the action of the second linkage component, thereby supporting the waiting part under the waiting part to ensure that the waiting part will not fall.

[0052] When the assembly table 2 continues to move until the assembly section 21 is directly below the second station 2a, the blocking part 422 is in the third position. At this time, the blocking part 422 opens the bottom end of the second slide 42, allowing the pre-assembled part to fall into the assembly section 21, while the support part 421 still supports the waiting part above, preventing the waiting part from falling and ensuring that only one bolt falls into the assembly section 21.

[0053] In some embodiments, see Figure 7 and Figure 9 The assembly unit 21 includes a rotating component 211, a picking component 212, and a motor 213. The rotating component 211 is rotatably mounted on the assembly table 2. The picking component 212 is laterally slidably mounted on the rotating component 211. The picking component 212 has an elastic degree of freedom to move towards the first station 1a and also has magnetism to attract bolts. The picking component 212 is used to pick up bolts located at the second station 2a. The motor 213 is fixedly mounted on the assembly table 2, and its output end is connected to the rotating component 211.

[0054] For details, please see Figure 9 A third spring 2123 is fixedly installed between the pickup component 212 and the rotating component 211, and the pickup component 212 is moved by the third spring 2123.

[0055] The elastic degree of freedom of the pickup 212 allows it to provide axial force to the bolt when it is mated with the nut, thereby pressing the bolt onto the nut and ensuring that the bolt can be threadedly connected to the nut during rotation. The magnetism of the pickup 212 ensures that the bolt will not fall off the pickup 212 during movement.

[0056] In some embodiments, see Figure 7 and Figure 9 The rotating component 211 has a material drop groove 2111. The picking component 212 has a groove 2121 that matches the head of the bolt, and the groove 2121 has a second notch 2122 in the vertical direction. When the assembly table 2 moves to the point where the material drop groove 2111 connects with the corresponding second slide rail 42, the pre-assembled component sequentially passes through the material drop groove 2111 and the second notch 2122 into the groove 2121.

[0057] It should be noted that the workbench 1 has a slot for bolts to fall into the feed chute 2111. The rotating component 211 has a slider with a groove closed at both ends. The slider is slidably disposed in the groove, which limits the range of movement of the slider, so that when the third spring 2123 is not subjected to external force, the position of the pickup component 212 is aligned vertically with the feed chute 2111 and the insert 2121. When the bolt on the pickup component 212 abuts against the nut at the first station 1a, the third spring 2123 is further compressed, so that the pickup component 212 can provide an axial force on the bolt toward the nut.

[0058] In some embodiments, see Figure 7 The assembly part 21 also includes two positioning parts 214, which are located on both sides of the groove 2121. The positioning parts 214 have an elastic degree of freedom to rotate into the groove 2121. The positioning parts 214 abut against the head of the bolt located in the groove 2121 so that the shank of the bolt is kept horizontal. A gap is formed between the two positioning parts 214 for the shank of the bolt to extend out.

[0059] For details, please see Figure 7 Two springs 2141 are fixedly provided on the pickup 212. The springs 2141 correspond one-to-one with the positioning part 214 and abut against the positioning part 214, thereby providing a pushing force to the positioning part 214.

[0060] Two positioning parts 214 clamp the bolt head from both sides using elastic force, pressing the bolt head firmly into the groove 2121 and keeping the bolt shank horizontal at all times, thus preventing misalignment when the bolt shank passes through the hoop plate through hole. Furthermore, when the bolt and nut are connected and the assembly table 2 moves towards the second station 2a, the two positioning parts 214 can open, allowing the bolt head to move out of the groove 2121.

[0061] In some embodiments, see Figure 1 and Figure 2 The workbench 1 has a third base 13, and the third base 13 has a receiving groove 131 for stacking two hoop plates. The position of the receiving groove 131 is the third work station 3a.

[0062] The shape of the receiving groove 131 perfectly matches the two stacked clamp plates, restricting the horizontal movement of the clamp plates and ensuring that the through holes on the flange plates are aligned with the axes of the bolts and nuts. The clamp plates are positioned within the receiving groove 131 to prevent displacement or wobbling during assembly, ensuring a smooth assembly process.

[0063] The implementation principle of the automatic assembly device for cable clamps provided by this invention is as follows: After the assembly part 21 picks up the bolt at the second station 2a, it moves the bolt towards the third station 3a, so that the shank of the bolt passes through the through hole in the clamp plate and abuts against the nut at the first station 1a. The picking part 212 is squeezed and moved, thereby providing a squeezing force on the bolt towards the nut by relying on elastic force. At the same time, the trigger part 413, pushed by the assembly table 2, drives the limiting part 412 through the first linkage component to fix the nut at the first station 1a. The rotating part 211 drives the picking part 212 to rotate, so that the bolt and nut are threaded together, completing the assembly of the clamp.

[0064] The assembly table 2, driven by the drive unit 3, returns to the second station 2a, causing the bolt head to push open the positioning part 214 and move out of the groove 2121. Simultaneously, due to the movement of the assembly table 2, the trigger part 413, under the action of elastic force, drives the limiting part 412 to move through the first linkage component, opening the first notch 411. At this point, the worker removes the assembled clamp and places a new clamp plate to be assembled at the third station 3a.

[0065] As the assembly table 2 moves toward the second workstation 2a, it pushes the blocking part 422 to move. The blocking part 422 drives the support part 421 to extend through the second linkage component. When the assembly part 21 moves to directly below the second workstation 2a, the bolt enters the groove 2121 along the drop groove 2111 and the second notch 2122 and is picked up by the assembly part 21, thus proceeding to assemble the next set of clamps.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
