Description

Technical Field

[0001] The present invention belongs to the technical field of drag chain assembly, and specifically relates to an automatic drag chain assembly device. Background Art

[0002] An automatic drag chain assembly device is an automatic device used to snap adjacent chain links to form a drag chain. The existing drag chain is formed by snapping multiple chain links, and it is used as a device to restrain cables, wires, air pressure pipes, and hydraulic pipes to facilitate their rotation and movement.

[0003] In the prior art, a feeding machine transports the chain links into an assembly groove plate, and then a push rod is used to push the chain links so that they are snapped onto one end of the drag chain fixed by a limiting device in the assembly groove plate, thereby completing the assembly. Subsequently, the limiting device moves a distance of one chain link and continues to limit the drag chain, repeating the above operations to complete the assembly of the drag chain. When the assembled drag chain reaches a predetermined length, the drag chain is taken out.

[0004] There are still some problems in the actual use of the existing automatic drag chain assembly device. During the assembly process, the chain links are directly placed in the assembly groove plate, while the drag chain is fixed by a limiting device. To prevent the groove spacing of the groove plate from being the same as the size of the chain links, resulting in friction between the surface of the chain links and the inner wall of the groove during the movement of the chain links, causing significant wear, the groove spacing of the existing groove plate is larger than the size of the chain links. This causes the chain links to shift during the process of the push rod pushing the chain links. This shift makes the chain links unable to accurately align and be fixed at the predetermined snapping position, resulting in the chain links not being able to fully embed into one end of the drag chain, reducing the stability of the drag chain formed after snapping.

[0005] Therefore, the present invention provides an automatic drag chain assembly device. Summary of the Invention

The first clamping plate slides in the first guiding groove block. A first return spring is fixedly connected between the first guiding groove block and the first clamping plate. A second limiting block is fixedly connected to one side of the top of the first clamping plate.

[0012] Preferably, the second limiting block is on the movement track of the first limiting block.

[0013] Preferably, a second guiding groove is formed on the top of the assembly block. A second guiding groove block is slidably connected in the second guiding groove. The third clamping plate slides in the second guiding groove block.

[0014] Preferably, a first gear rod is rotatably connected inside the assembly block. Second guiding racks are symmetrically and slidably arranged on both sides of the first gear rod. A second gear rod is fixedly connected to the top of the first gear rod. First guiding racks are symmetrically and slidably connected to both sides of the second gear rod. One end of a first guiding rack is fixedly connected to a first connecting block. The other end of the first guiding rack is fixedly connected to one side of a guiding groove block one.

[0016] Preferably, a limiter is arranged at the bottom of the assembly groove. The limiter is composed of two positioning plates and two hydraulic cylinders.

[0017] Preferably, a contraction assembly is arranged on the limiting groove. The contraction assembly includes a screw rod. A third clamping plate is rotatably arranged on the screw rod.

[0019] An automated assembly method for a drag chain specifically includes:

[0020] Step 1: Preparation work: Put the link sections formed after assembly into the feeding device.

[0021] Step 2: Assembly: Start the feeding device, so that the chain links enter the feeding trough through the feeding device. Subsequently, contract the first shrinkage trough, and under the action of the conveying device, make the chain links enter the assembly trough. Fix the chain links in alignment through the alignment component, and push the assembly block to move by the crimping post, so that the chain links move away from the third electric telescopic rod. During this process, contract the clamping plate three through the contraction component. Subsequently, the alignment component resets. During this process, contract the clamping plate three through the contraction component. Clamp the previous chain link horizontally through the assembly device, and make the chain link move a distance of one chain link away from the third electric telescopic rod. After that, the assembly device returns to the initial state, and then the alignment component resets; repeat the above steps to make the next chain link enter the assembly trough. At this time, fix the previous chain link in the assembly trough through the alignment component, and at the same time fix this chain link in alignment, and clamp and fix it through the assembly device. At this time, push the assembly block to move by the crimping post. During this process, since the clamping plate three contracts, the clamping plate three no longer blocks the clamping between the two chain links, thus completing the clamping between the two chain links and forming a drag chain;

[0022] Step 3: Complete assembly: Subsequently, continue to repeat the above operations to complete the assembly of the drag chain. When the drag chain is assembled to the required length, stop the machine and take out the drag chain.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. While clamping the chain links on the assembly block in alignment, the present invention also clamps the chain links on the limiter in the assembly trough in alignment, making the previous chain link and the next chain link on the same horizontal straight line, preventing the chain links from shifting when pushed by the crimping post, so that the chain links cannot be accurately aligned and fixed at the predetermined clamping position, resulting in the problem that the chain links cannot be fully embedded at one end of the drag chain, reducing the stability of the drag chain formed after clamping, improving the alignment accuracy between the chain links, ensuring the stability of the drag chain formed after docking, and also improving the qualified rate of the produced drag chain.

[0025] 2. Through the meshing of the transmission rack and the transmission gear sleeve, the present invention cleverly contracts the clamping plate three into the internal space of the second guiding groove block. This mechanism ensures that the clamping plate three no longer becomes an obstacle to the smooth clamping between two adjacent chain links. Thus, not only realizes the alignment and fixation of the chain links on the assembly block, greatly improving the stability and accuracy during clamping, but also ensures that this chain link can form a tight and effective clamping connection with the previous chain link without any hindrance.

[0039] In order to make the technical means, creative features, achieved objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] Embodiment 1

[0041] As Figures 1 to 10 shown, a drag chain automatic assembly device according to an embodiment of the present invention includes a base 2, a feeding device 1 is arranged on one side of the base 2, a workbench 3 is fixedly arranged on the top of the base 2, an assembly groove 31 is fixedly connected to the top of the workbench 3, a feeding groove 4 is fixedly arranged directly between the assembly groove 31 and the feeding device 1, and a conveying device 5 is fixedly arranged on the top of the assembly groove 31;

[0042] An electric telescopic rod one 6 is fixedly connected to the top of the assembly groove 31, a displacement block 61 is slidably arranged on the top of the assembly groove 31, a contact one 62 is fixedly connected to one side of the displacement block 61, a contact two 63 is fixedly arranged on the top of the assembly groove 31, a contraction groove one 64 is opened at the bottom of the feeding groove 4, a part of the contraction groove one 64 is opened on the top of the assembly groove 31, an electric telescopic rod two 65 is fixedly connected to the bottom of the contraction groove one 64, a baffle 66 is slidably connected in the contraction groove one 64, a limit block one 67 is fixedly connected to the top of one side of the baffle 66, and the shape of the baffle 66 matches the shape of the contraction groove one 64;

[0043] An electric telescopic rod three 7 is fixedly connected to one end of the assembly groove 31, a crimping column 71 is fixedly connected to the output end of the electric telescopic rod three 7, the crimping column 71 penetrates through one end of the assembly groove 31, and an assembly device 8 is fixedly arranged on the top of the workbench 3;

[0044] A centering component is arranged at the bottom of the assembly groove 31. The centering component includes a clamping plate one 95, an assembly block 92 is slidably arranged in the assembly groove 31, a clamping plate two 98 is slidably connected to the inner bottom surface of the assembly groove 31, a clamping plate three 911 is slidably arranged at one end of the bottom of the assembly groove 31, and a clamping plate four 912 is slidably arranged at the other end. When the clamping plate one 95 and the clamping plate two 98 contract inward, the chain link is clamped and still in a centered state.

[0045] Specifically, there are still some problems in the actual use of the existing drag chain automatic assembly device. During the assembly process, the chain link is directly placed in the assembly groove 31, and the drag chain is clamped and fixed by the assembly device 8. In order to prevent the groove spacing of the assembly groove 31 from being the same as the size of the chain link, resulting in friction between the surface of the chain link and the inner wall of the assembly groove 31 during the movement of the chain link, causing greater wear, the groove spacing of the existing assembly groove 31 is larger than the size of the chain link. When the crimping column 71 pushes the chain link, the chain link will shift. This shift will cause the chain link to not be able to accurately align and be fixed at the predetermined clamping position, resulting in the chain link not being able to be completely embedded in one end of the drag chain, reducing the stability of the formed drag chain after clamping.

[0046] Therefore, the present invention solves this problem by setting corresponding structures. First, start the feeding device 1, so that the chain links enter the feeding trough 4 through the feeding device 1. Subsequently, start the first electric telescopic rod 6 to extend, so that the contact point 62 on the displacement block 61 contacts the contact point 63, and then the first contraction groove 64 contracts, so that the baffle 66 no longer blocks the chain links from entering the assembly groove 31. While the first contraction groove 64 contracts, under the action of the conveying device 5, a chain link enters the assembly groove 31. At this time, the chain link is centered and fixed by the centering component, and the assembly block 92 is pushed to move by the crimping column 71, so that the chain link moves away from the third electric telescopic rod 7. During this process, the clamping plate three 911 contracts through the contraction component, and the previous chain link is clamped and horizontally moved by the assembly device 8, so that the chain link moves a distance of one chain link away from the third electric telescopic rod 7. After that, the assembly device 8 returns to the initial state, and then the centering component resets;

[0047] Repeat the above steps to make the next chain link enter the assembly groove 31. At this time, the previous chain link in the assembly groove 31 is fixed by the centering component, and at the same time, this chain link is centered and fixed, and is clamped and fixed by the assembly device 8. At this time, the assembly block 92 is pushed to move by the crimping column 71. During this process, since the clamping plate three 911 contracts, the clamping plate three 911 no longer blocks the clamping between the two chain links, and thus the clamping between the two chain links is completed, forming a drag chain;

[0048] Subsequently, continue to repeat the above operations to complete the assembly of the drag chain. When the drag chain is assembled to the required length, stop the machine and take out the drag chain.

[0049] Embodiment 2

[0050] As Figures 2 to 10 shown, compared with Embodiment 1, another implementation manner of the present invention is:

[0051] As Figures 3 to 9 shown, the centering component in this embodiment further includes a limiting groove 91. The limiting groove 91 is opened at the bottom of the assembly groove 31. The assembly block 92 slides in the limiting groove 91. One side of the limiting groove 91 is provided with a second telescopic groove 925. A second reset spring 926 is fixedly connected between the inner wall of one end of the second telescopic groove 925 and the assembly block 92. One side of the top of the assembly block 92 is provided with a first guiding groove 93. A first guiding groove block 94 is slidably connected in the first guiding groove 93. The clamping plate one 95 slides in the first guiding groove block 94. A first reset spring 96 is fixedly connected between the first guiding groove block 94 and the clamping plate one 95. One side of the top of the clamping plate one 95 is fixedly connected with a second limiting block 97. The second limiting block 97 is on the movement track of the first limiting block 67. The top of the assembly block 92 is provided with a second guiding groove 99. A second guiding groove block 910 is slidably connected in the second guiding groove 99. The clamping plate three 911 slides in the second guiding groove block 910;

[0052] A gear rod one 913 is rotatably connected inside the assembly block 92. On both sides of the gear rod one 913, guide racks two 917 are symmetrically arranged in a sliding manner. At the top of the gear rod one 913, a gear rod two 914 is fixedly connected. On both sides of the gear rod two 914, guide racks one 915 are symmetrically connected in a sliding manner. One end of a guide rack one 915 is fixedly connected with a connection block one 916, and one end of the other guide rack one 915 is fixedly connected to one side of the guide groove block one 94. The end of the connection block one 916 away from the guide rack one 915 is fixed to the bottom of the clamping plate four 912. One end of a guide rack two 917 is fixedly connected with a connection block two 918, and one end of the other guide rack two 917 is fixedly connected to one side of the guide groove block two 910. The end of the connection block two 918 away from the guide rack two 917 is fixed to the bottom of the clamping plate four 912. The two guide racks one 915 are arranged in a staggered manner, and the two guide racks two 917 are arranged in a staggered manner.

[0053] Specifically, during the downward movement of the baffle 66, the limit block one 67 contacts the limit block two 97, thereby driving the limit block two 97 to move synchronously, causing the clamping plate one 95 to contract into the guide groove block one 94 and elastically compress the reset spring one 96 until the baffle 66 stops moving. At this time, the clamping plate one 95 is completely contracted into the guide groove block one 94, so that the chain links on the feeding groove 4 are no longer blocked and can enter the assembly groove 31.

[0054] When the baffle 66 is reset, through the above operations, under the action of the elastic extension of the reset spring one 96, the clamping plate one 95 is reset. Subsequently, the external motor on the gear rod one 913 is started, causing the gear rod one 913 to start rotating. The rotation of the gear rod one 913 drives the gear rod two 914 to rotate synchronously. Through the rotation of the gear rod one 913, the guide groove block two 910 and the connection block two 918 move towards the middle of the gear rod one 913, causing the clamping plate four 912 and the clamping plate three 911 to clamp both ends of the chain link. At the same time, through the rotation of the gear rod two 914, the guide groove block one 94 and the reset spring one 96 move towards the middle of the gear rod two 914, thereby driving the assembly block 92 to move, causing the clamping plate one 95 and the clamping plate two 98 to clamp both sides of the chain link, thereby centering and limiting the chain link.

[0055] During the process of the chain link being clamped, the assembly block 92 moves away from the electric telescopic rod three 7. At this time, the reset spring two 926 is elastically stretched as the assembly block 92 moves.

[0056] After the assembly is completed, the crimping column 71 is reset by the contraction of the electric telescopic rod three 7. At this time, the assembly block 92 is reset under the action of the elastic contraction of the reset spring two 926.

[0057] As Figure 6As shown in the figure, a limiter 919 is provided at the bottom of the assembly groove 31 in this embodiment. The limiter 919 is composed of two positioning plates and two hydraulic cylinders.

[0058] Specifically, while the chain link is centered and clamped, by starting the hydraulic cylinder, the output end thereof drives the positioning plate to move towards the middle of the assembly groove 31, thereby completing the clamping of the chain link between the two positioning plates.

[0059] While centering and clamping the chain link on the assembly block 92, the present invention also centers and clamps the chain link on the limiter 919 in the assembly groove 31, so that the previous chain link and the subsequent chain link are on the same horizontal straight line, preventing the chain link from shifting when being pushed by the crimping column 71, which may cause the chain link to fail to accurately align and be fixed at the predetermined clamping position, resulting in the chain link being unable to be fully embedded into one end of the drag chain, and reducing the stability of the drag chain formed after clamping. This improves the alignment accuracy between the chain links, ensures the stability of the drag chain formed after docking, and also improves the yield rate of the produced drag chain.

[0060] As Figure 10 shown in the figure, a contraction assembly is provided on the limit groove 91 in this embodiment. The contraction assembly includes a screw rod 920. The third clamping plate 911 is rotatably arranged on the screw rod 920. By rotating the screw rod 920, the third clamping plate 911 contracts into the second guide groove block 910, enabling the two chain links to be clamped. The contraction assembly further includes a transmission gear sleeve 923, which is fixed on the bottom surface of the screw rod 920. An expansion slot 921 is formed on the third clamping plate 911, and a spiral guide block 922 is fixedly connected in the expansion slot 921. The shape of the spiral guide block 922 matches the shape of the screw rod 920. One end of the limit groove 91 is fixedly connected with a transmission rack 924.

[0061] Specifically, during the process of the crimping column 71 pushing the assembly block 92 to move, the transmission rack 924 penetrates through the second guide groove block 910, enabling the transmission rack 924 to mesh with the transmission gear sleeve 923. Since the third clamping plate 911 slides in the second guide groove block 910, the rotation of the transmission gear sleeve 923 drives the screw rod 920 to rotate synchronously, causing the spiral guide block 922 in the expansion slot 921 to slide along the shape of the thread on the screw rod 920, thereby driving the third clamping plate 911 to contract into the second guide groove block 910, and no longer blocking the chain link until the second guide groove block 910 abuts against one end of the limit groove 91. At this time, the two chain links are clamped with each other, thereby forming a chain.

[0062] When the assembly block 92 resets, the transmission gear sleeve 923 rotates in the reverse direction, and through the above operation, the third clamping plate 911 resets.

[0063] Through the engagement of the transmission rack 924 and the transmission gear sleeve 923, the third clamping plate 911 is ingeniously retracted into the internal space of the guide groove block two 910. This mechanism ensures that the third clamping plate 911 no longer becomes an obstacle to the smooth clamping between two adjacent linkages. Thus, not only is the centering and fixation of the linkages on the assembly block 92 achieved, greatly enhancing the stability and accuracy during clamping, but also it is ensured that the linkage can form a tight and effective clamping connection with the previous linkage without any hindrance.

[0064] An automated assembly method for a drag chain specifically includes:

[0065] Step 1: Preparation work: Place the formed linkages after assembly into the feeding device 1.

[0066] Step 2: Assembly: Start the feeding device 1 to enable the linkages to enter the feeding groove 4 through the feeding device 1. Subsequently, contract the first contraction groove 64, and under the action of the conveying device 5, enable the linkages to enter the assembly groove 31. Center and fix the linkages through the centering component, and push the assembly block 92 to move by the crimping post 71, causing the linkages to move in the direction away from the third electric telescopic rod 7. During this process, contract the third clamping plate 911 through the contraction component. Subsequently, the centering component resets. During this process, contract the third clamping plate 911 through the contraction component. Clamp the previous linkage by the assembly device 8 and move horizontally, causing the linkages to move a distance equal to one linkage in the direction away from the third electric telescopic rod 7. Then, the assembly device 8 returns to the initial state. Subsequently, the centering component resets; repeat the above steps to enable the next linkage to enter the assembly groove 31. At this time, fix the previous linkage in the assembly groove 31 through the centering component, and at the same time center and fix this linkage and clamp and fix it through the assembly device 8. At this time, push the assembly block 92 to move by the crimping post 71. During this process, since the third clamping plate 911 contracts, the third clamping plate 911 no longer blocks the clamping between the two linkages, thereby completing the clamping between the two linkages and forming a drag chain.

[0067] Step 3: Complete assembly: Subsequently, continue to repeat the above operations to complete the assembly of the drag chain. When the drag chain is assembled to the required length, stop the machine and take out the drag chain.

[0068] Working principle:

[0069] First, start the feeding device 1, so that the chain links enter the feeding trough 4 through the feeding device 1. Subsequently, start the first electric telescopic rod 6 to extend, so that the first contact point 62 on the displacement block 61 contacts the second contact point 63, thereby causing the first contraction groove 64 to contract, and further causing the baffle 66 to contract. During this process, the first limiting block 67 contacts the second limiting block 97, thereby driving the second limiting block 97 to move synchronously, causing the first clamping plate 95 to contract into the first guiding groove block 94 and elastically compress the first reset spring 96 until the baffle 66 stops moving. At this time, the first clamping plate 95 is completely contracted into the first guiding groove block 94, so that the chain links on the feeding trough 4 are no longer blocked. While the first contraction groove 64 contracts, under the action of the conveying device 5, a chain link enters the assembly groove 31;

[0070] When the baffle 66 resets, through the above operations, under the elastic extension of the first reset spring 96, the first clamping plate 95 resets. Subsequently, start the external motor on the first gear rod 913, so that the first gear rod 913 starts to rotate. The rotation of the first gear rod 913 drives the second gear rod 914 to rotate synchronously. Through the rotation of the first gear rod 913, the second guiding groove block 910 and the second connecting block 918 move towards the middle of the first gear rod 913, causing the fourth clamping plate 912 and the third clamping plate 911 to clamp both ends of the chain link. At the same time, through the rotation of the second gear rod 914, the first guiding groove block 94 and the first reset spring 96 move towards the middle of the second gear rod 914, thereby driving the assembly block 92 to move, causing the first clamping plate 95 and the second clamping plate 98 to clamp both sides of the chain link, thereby centering and limiting the chain link;

[0071] While the chain link is being centered and clamped, start the hydraulic cylinder, and its output end drives the positioning plate to move towards the middle of the assembly groove 31;

[0072] Subsequently, push the assembly block 92 to move through the crimping column 71, so that the assembly block 92 moves away from the third electric telescopic rod 7. At this time, the second reset spring 926 is elastically stretched as the assembly block 92 moves, and the chain link moves away from the third electric telescopic rod 7 together with the assembly block 92;

[0073] During this process, the transmission rack 924 will penetrate the second guiding groove block 910, causing the transmission rack 924 to mesh with the transmission gear sleeve 923. Since the third clamping plate 911 slides in the second guiding groove block 910, the rotation of the transmission gear sleeve 923 drives the screw rod 920 to rotate synchronously, causing the spiral guiding block 922 in the first telescopic groove 921 to slide along the thread shape on the screw rod 920, thereby driving the third clamping plate 911 to contract into the second guiding groove block 910, and thus no longer blocking the chain link until the second guiding groove block 910 abuts against one end of the limiting groove 91

[0074] At this time, after gripping the previous link by the assembling device 8 and horizontally moving it, when the link moves a distance of one link away from the electric telescopic rod III 7, the assembling device 8 returns to the initial state, and then the centering component resets;

[0075] Repeat the above steps to enable the next link to enter the assembling groove 31. At this time, fix the previous link in the assembling groove 31 through the centering component, and at the same time center and fix this link, and grip and fix it through the assembling device 8. At this time, push the assembling block 92 to move through the crimping column 71. During this process, since the clamping plate III 911 contracts, the clamping plate III 911 no longer blocks the clamping between the two links, thereby completing the clamping between the two links and forming a drag chain;

[0076] Subsequently, continue to repeat the above operations to complete the assembly of the drag chain. When the drag chain is assembled to the required length, stop the machine and take out the drag chain.
