Description

Technical Field

[0001] The invention belongs to the technical field of drag chain assembly, in particular to a drag chain automatic assembly device. Background Art

[0002] The automated assembly equipment for drag chains is an automated device used to connect adjacent chain links to form a drag chain. Existing drag chains are formed by connecting multiple chain links. They are 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, the loader conveys the chain links into the assembly groove plate, and then pushes the chain links through the push rod so that it engages with one end of the drag chain fixed by the limiting device in the assembly groove plate, thereby completing the assembly, and then moves the chain link a distance through the limiting device, and allows the limiting device to continue to limit the drag chain, repeating the above operations, thereby completing the assembly of the drag chain, and 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 drag chain automated assembly equipment. During the assembly process, the chain links are directly placed in the assembly groove plate, and the drag chain is fixed by a limiting device. In order to prevent the groove spacing of the groove plate from being the same as the size of the chain link, resulting in the surface of the chain link rubbing against the inner wall of the groove during movement, causing greater wear, the groove spacing of the existing groove plate is larger than the size of the chain link, so that the chain link will be offset when the push rod pushes the chain link. This offset will make it impossible for the chain link to be accurately aligned and fixed at the predetermined clamping position, resulting in the chain link being unable to be fully embedded in one end of the drag chain, reducing the stability of the drag chain formed after clamping.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figures 1 to 10 As shown, an automatic assembly device for a drag chain according to an embodiment of the present invention comprises 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 directly fixedly arranged on 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 6 is fixedly connected to the top of the assembly groove 31, a displacement block 61 is slidably provided on the top of the assembly groove 31, a contact 62 is fixedly connected to one side of the displacement block 61, a contact 63 is fixedly provided on the top of the assembly groove 31, a contraction groove 64 is provided at the bottom of the loading groove 4, the contraction groove 64 is partially provided at the top of the assembly groove 31, an electric telescopic rod 65 is fixedly connected to the bottom of the contraction groove 64, a baffle 66 is slidably connected in the contraction groove 64, a limiting block 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 64;

[0043] One end of the assembly slot 31 is fixedly connected to an electric telescopic rod 3 7, and the output end of the electric telescopic rod 3 7 is fixedly connected to a crimping column 71, which passes through one end of the assembly slot 31, and an assembly device 8 is fixedly provided on the top of the workbench 3;

[0044] A centering component is provided at the bottom of the assembly groove 31, and the centering component includes a clamping plate 1 95. An assembly block 92 is slidably provided in the assembly groove 31, and a clamping plate 2 98 is slidably connected to the bottom surface of the assembly groove 31. A clamping plate 3 911 is slidably provided at one end of the bottom of the assembly groove 31, and a clamping plate 4 912 is slidably provided at the other end. The chain links are clamped and in a centering state while being in an inward contraction of the clamping plate 1 95 and the clamping plate 2 98.

[0045] Specifically, the existing automated assembly equipment for drag chains still has some problems during actual use. During the assembly process, the chain links are directly placed in the assembly grooves 31, and the drag chains are clamped and fixed by the assembly device 8. In order to prevent the groove spacing of the assembly grooves 31 from being the same as the size of the chain links, causing the surface of the chain links to rub against the inner wall of the assembly grooves 31 during movement, resulting in greater wear, the groove spacing of the existing assembly grooves 31 is larger than the size of the chain links, causing the chain links to shift during the process of being pushed by the crimping columns 71. This shift will prevent the chain links from being accurately aligned and fixed at the predetermined clamping position, resulting in the chain links being unable to be fully embedded in one end of the drag chain, reducing the stability of the drag chain formed after clamping.

[0046] Therefore, the present invention solves this problem by setting a corresponding structure. First, the feeding device 1 is started to make the chain link enter the feeding trough 4 through the feeding device 1, and then the electric telescopic rod 1 6 is started to extend, so that the contact 1 62 on the displacement block 61 contacts the contact 2 63, and then the contraction groove 1 64 is contracted, so that the baffle 66 no longer blocks the chain link from entering the assembly groove 31. While the contraction groove 1 64 is contracted, a chain link enters the assembly groove 31 under the action of the conveying device 5. 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 in the direction away from the electric telescopic rod 3 7. In this process, the clamping plate 3 911 is contracted by the contraction component, and the assembly device 8 clamps the previous chain link and then moves horizontally, so that the chain link moves a distance of a chain link in the direction away from the electric telescopic rod 3 7, and then the assembly device 8 returns to the initial state, and then the centering component is reset;

[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 the chain link is fixed by centering and clamped by the assembly device 8. At this time, the assembly block 92 is pushed to move by the crimping column 71. During this process, the clamping plate 3 911 shrinks, so that the clamping plate 3 911 no longer blocks the clamping connection between the two chain links, thereby completing the clamping connection between the two chain links and forming a drag chain.

[0048] Then 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] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0051] like Figures 3 to 9 As shown, the centering component of this embodiment also includes a limiting groove 91, which is provided at the bottom of the assembly groove 31, and the assembly block 92 slides in the limiting groove 91. A telescopic groove 925 is provided on one side of the limiting groove 91, and a return spring 926 is fixedly connected between the inner wall of one end of the telescopic groove 925 and the assembly block 92. A guide groove 93 is provided on one side of the top of the assembly block 92, and a guide groove block 94 is slidably connected in the guide groove 93. A clamping plate 95 slides in the guide groove block 94, and a return spring 96 is fixedly connected between the guide groove block 94 and the clamping plate 95. A limiting block 97 is fixedly connected to one side of the top of the clamping plate 95, and the limiting block 97 is on the motion trajectory of the limiting block 67. A guide groove 99 is provided on the top of the assembly block 92, and a guide groove block 910 is slidably connected in the guide groove 99, and a clamping plate 911 slides in the guide groove block 910.

[0052] A gear rod 913 is rotatably connected inside the assembly block 92, and guide racks 917 are symmetrically and slidably arranged on both sides of the gear rod 913. A gear rod 914 is fixedly connected to the top of the gear rod 913, and guide racks 915 are symmetrically and slidably connected on both sides of the gear rod 914. One end of a guide rack 915 is fixedly connected to a connecting block 916, and one end of another guide rack 915 is fixedly connected to one side of the guide groove block 94. The end of the connecting block 916 away from the guide rack 915 is fixed to the bottom of the clamping plate 4 912, one end of a guide rack 917 is fixedly connected to a connecting block 2 918, and one end of the other guide rack 917 is fixedly connected to one side of the guide groove block 2 910, and the end of the connecting block 2 918 away from the guide rack 2 917 is fixed to the bottom of the clamping plate 4 912. The two guide racks 915 are staggered, and the two guide racks 917 are staggered.

[0053] Specifically, during the downward movement of the baffle 66, the limit block 1 67 contacts the limit block 2 97, thereby driving the limit block 2 97 to move synchronously, so that the clamping plate 1 95 contracts toward the guide groove block 1 94 and elastically compresses the return spring 1 96 until the baffle 66 stops moving. At this time, the clamping plate 1 95 is completely contracted into the guide groove block 1 94, so that the chain link on the loading chute 4 is no longer blocked, and can enter the assembly groove 31;

[0054] When the baffle 66 is reset, through the above operation, under the action of the elastic extension of the reset spring 1 96, the clamping plate 1 95 is reset, and then the external motor on the gear rod 1 913 is started to make the gear rod 1 913 start to rotate. The rotation of the gear rod 1 913 drives the gear rod 2 914 to rotate synchronously. Through the rotation of the gear rod 1 913, the guide groove block 2 910 and the connecting block 2 918 move toward the direction close to the middle of the gear rod 1 913, so that the clamping plate 4 912 and the clamping plate 3 911 clamp the two ends of the chain link. At the same time, through the rotation of the gear rod 2 914, the guide groove block 1 94 and the reset spring 1 96 move toward the direction close to the middle of the gear rod 2 914, thereby driving the assembly block 92 to move, so that the clamping plate 1 95 and the clamping plate 2 98 clamp the two sides of the chain link, thereby centering and limiting the chain link.

[0055] During the process of the chain link being connected, the assembly block 92 moves in a direction away from the electric telescopic rod 3 7, and at this time, the return spring 2 926 elastically stretches with the movement of the assembly block 92;

[0056] After the assembly is completed, the crimping column 71 is reset by contracting the electric telescopic rod 3 7 , and the assembly block 92 is reset under the elastic contraction of the reset spring 2 926 .

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

[0058] Specifically, while the chain link is being centrally clamped, the hydraulic cylinder is activated so that its output end drives the positioning plate to move toward the middle of the assembly groove 31, thereby completing the clamping of the chain link between the two positioning plates.

[0059] The present invention performs centering clamping on the chain links on the assembly block 92 and the chain links on the limiter 919 in the assembly groove 31, so that the previous chain link and the subsequent chain link are in the same horizontal straight line, preventing the chain links from being offset when pushed by the crimping column 71, making it impossible for the chain links to be accurately aligned and fixed in the predetermined clamping position, resulting in the chain links being unable to be completely embedded in one end of the drag chain, causing the stability of the drag chain formed after the clamping to be reduced. The docking accuracy between the chain links is improved, the stability of the drag chain formed after the docking is ensured, and the yield rate of the produced drag chain is also improved.

[0060] like Fig.10 As shown, in this embodiment, a contraction component is provided on the limit groove 91, and the contraction component includes a screw rod 920. The clamping plate three 911 is rotatably provided on the screw rod 920. The clamping plate three 911 is contracted into the guide groove block two 910 through the rotation of the screw rod 920, so that the two chain links are clamped. The contraction component also includes a transmission gear sleeve 923, and the transmission gear sleeve 923 is fixed to the bottom surface of the screw rod 920. The clamping plate three 911 is provided with a telescopic groove one 921, and a spiral guide block 922 is fixedly connected in the telescopic groove one 921. The shape of the spiral guide block 922 matches the shape of the screw rod 920. A transmission rack 924 is fixedly connected to one end of the limit groove 91.

[0061] Specifically, when the crimping column 71 pushes the assembly block 92 to move, the transmission rack 924 will penetrate the guide groove block 2 910, so that the transmission rack 924 is meshed with the transmission gear sleeve 923. Because the clamping plate 3 911 slides in the guide groove block 2 910, the rotation of the transmission gear sleeve 923 drives the spiral rod 920 to rotate synchronously, so that the spiral guide block 922 in the telescopic groove 1 921 slides along the shape of the thread on the spiral rod 920, and then drives the clamping plate 3 911 to shrink into the guide groove block 2 910, and then no longer blocks the chain link, until the guide groove block 2 910 conflicts with one end of the limit groove 91, at which time the two chain links are mutually engaged, thereby forming a chain;

[0062] When the assembly block 92 is reset, the transmission gear sleeve 923 rotates in the opposite direction. Through the above operation, the clamping plate three 911 is reset.

[0063] The present invention cleverly shrinks the clamping plate three 911 to the internal space of the guide groove block two 910 through the meshing of the transmission rack 924 and the transmission gear sleeve 923. This mechanism ensures that the clamping plate three 911 no longer becomes an obstacle to the smooth clamping between two adjacent chain links. Therefore, not only the centering and fixation of the chain link on the assembly block 92 is achieved, which greatly improves the stability and accuracy of the clamping, but also ensures that the chain link can form a tight and effective clamping connection with the previous chain link without any hindrance.

[0064] A drag chain automated assembly method specifically includes:

[0065] Step 1: Preparation: Place the assembled chain link into the loading device 1;

[0066] Step 2: Assembly: Start the feeding device 1, so that the chain link passes through the feeding device 1 and enters the feeding trough 4, then the contraction groove 64 is contracted, and the chain link enters the assembly groove 31 under the action of the conveying device 5, and the chain link is fixed in the center by the centering component, and the assembly block 92 is pushed to move by the crimping column 71, so that the chain link moves in the direction away from the electric telescopic rod 3 7. In this process, the clamping plate 3 911 is contracted by the contraction component, and then the centering component is reset. In this process, the clamping plate 3 911 is contracted by the contraction component, and the assembly device 8 clamps the previous chain link and then moves horizontally, so that After the chain link moves a distance of one chain link in the direction away from the electric telescopic rod 3 7, the assembly device 8 returns to the initial state, and then the centering component is reset; the above steps are repeated to allow the next chain link to enter the assembly groove 31. At this time, the previous chain link in the assembly groove 31 is fixed by the centering component, and the chain link is fixed and clamped by the assembly device 8. At this time, the assembly block 92 is pushed to move by the crimping column 71. During this process, the clamping plate 3 911 contracts, so that the clamping plate 3 911 no longer blocks the clamping connection between the two chain links, thereby completing the clamping connection between the two chain links and forming a drag chain;

[0067] Step 3: Complete the assembly: Then continue to repeat the above steps 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, the feeding device 1 is started, so that the chain link passes through the feeding device 1 and enters the feeding trough 4, and then the electric telescopic rod 1 is started to extend, so that the contact 1 62 on the displacement block 61 contacts the contact 2 63, thereby contracting the contraction groove 1 64, and then contracting the baffle 66. In this process, the limit block 1 67 contacts the limit block 2 97, thereby driving the limit block 2 97 to move synchronously, so that the clamping plate 1 95 contracts toward the guide groove block 1 94 and elastically compresses the return spring 1 96 until the baffle 66 stops moving. At this time, the clamping plate 1 95 is completely contracted into the guide groove block 1 94, so that the chain link on the feeding trough 4 is no longer blocked. While the contraction groove 1 64 contracts, a chain link enters the assembly groove 31 under the action of the conveying device 5;

[0070] When the baffle 66 is reset, through the above operation, under the action of the elastic extension of the reset spring 1 96, the clamping plate 1 95 is reset, and then the external motor on the gear rod 1 913 is started to make the gear rod 1 913 start to rotate. The rotation of the gear rod 1 913 drives the gear rod 2 914 to rotate synchronously. Through the rotation of the gear rod 1 913, the guide groove block 2 910 and the connecting block 2 918 move toward the direction close to the middle of the gear rod 1 913, so that the clamping plate 4 912 and the clamping plate 3 911 clamp the two ends of the chain link. At the same time, through the rotation of the gear rod 2 914, the guide groove block 1 94 and the reset spring 1 96 move toward the direction close to the middle of the gear rod 2 914, thereby driving the assembly block 92 to move, so that the clamping plate 1 95 and the clamping plate 2 98 clamp the two sides of the chain link, thereby centering and limiting the chain link.

[0071] While the chain link is being clamped in the center, the hydraulic cylinder is activated so that its output end drives the positioning plate to move toward the middle of the assembly groove 31;

[0072] Then, the assembly block 92 is pushed to move by the crimping column 71, so that the assembly block 92 moves in a direction away from the electric telescopic rod 3 7. At this time, the return spring 2 926 elastically stretches with the movement of the assembly block 92, and at the same time, the chain link moves together with the assembly block 92 in a direction away from the electric telescopic rod 3 7.

[0073] During this process, the transmission rack 924 will penetrate the guide groove block 2 910, so that the transmission rack 924 is meshed with the transmission gear sleeve 923. Because the clamping plate 3 911 slides in the guide groove block 2 910, the rotation of the transmission gear sleeve 923 drives the spiral rod 920 to rotate synchronously, so that the spiral guide block 922 in the telescopic groove 1 921 slides along the shape of the thread on the spiral rod 920, thereby driving the clamping plate 3 911 to shrink into the guide groove block 2 910, and no longer blocking the chain link until the guide groove block 2 910 contacts one end of the limit groove 91.

[0074] At this time, the assembly device 8 clamps the previous chain link and moves horizontally, so that the chain link moves a distance of one chain link in the direction away from the electric telescopic rod 3 7, and then the assembly device 8 returns to the initial state, and then the centering assembly is reset;

[0075] 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 the chain link is fixed by centering and clamped by the assembly device 8. At this time, the assembly block 92 is pushed to move by the crimping column 71. During this process, the clamping plate 3 911 shrinks, so that the clamping plate 3 911 no longer blocks the clamping connection between the two chain links, thereby completing the clamping connection between the two chain links and forming a drag chain.

[0076] Then 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.
