Description

A riveting device for duct processing Technical Field

[0001] This utility model relates to a duct processing method, specifically a riveting device for duct processing. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. They can be classified according to cross-sectional shape and material. During their processing, riveting equipment is needed to rivet and fix the fittings on them.

[0003] However, blind rivets are commonly used fasteners in the riveting process of duct fabrication. Their installation requires first passing the rivet through a through hole, and then applying tension to move the rivet core for fixation. Since the ideal tension required for different rivet core sizes varies, and existing riveting equipment generally lacks tension adjustment functionality, two problems often arise in actual operation: firstly, excessive tension causes premature breakage of the rivet core; secondly, insufficient tension prevents the rivet core from moving effectively. Both of these situations directly affect the fixing effect of the rivet, thereby reducing the overall riveting quality. Therefore, this utility model provides a riveting device for duct fabrication to solve the above-mentioned problems. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figure 1. In this embodiment of the present invention, a riveting device for duct processing includes a workbench 10, a support frame 15 mounted on the top of the workbench 10, a riveting assembly for processing workpieces mounted on the top of the support frame 15, a placement platform 12 for placing workpieces mounted on the bottom of the riveting assembly, a material unloading track 14 for unloading material mounted on the top of the workbench 10 on one side of the placement platform 12, and a robotic arm 13 for assisting unloading material mounted on the support frame 15 on one side of the riveting assembly. When processing is required, the workpiece is placed on the top of the placement platform 12 and riveted by the riveting assembly. After riveting, the workpiece is transferred to the material unloading track 14 by the robotic arm 13 for unloading.

[0028] Referring to Figure 2, the riveting assembly includes a drive motor 11, a connecting plate 20, a first electric lifting rod 21, an adjusting seat 23, a connecting seat 24, and a guide seat 25. The drive motor 11 and the first electric lifting rod 21 are respectively installed at the top and bottom of the support frame 15. The first electric lifting rod 21 is electrically connected to the drive motor 11. The connecting plate 20 is installed at the bottom end of the first electric lifting rod 21, and the adjusting seat 23, connecting seat 24, and guide seat 25 are installed from top to bottom at the middle of the bottom end of the connecting plate 20. The support frame 15 has telescopic rods 22 for limiting the position at both ends. The bottom end of the telescopic rods 22 is fixedly connected to the top outer wall of the connecting plate 20. The guide seat 25 has a through hole that extends to the inner wall of the adjusting seat 23. When docking is required, the first electric lifting rod 21 is driven to rise and fall by the drive motor 11. Then, the adjusting seat 23, the connecting seat 24 and the guide seat 25 at the bottom are moved down by the connecting plate 20. The rivet core can then pass through the through hole and enter the inner wall of the adjusting seat 23.

[0029] Referring to Figure 3, the inner wall of the adjusting seat 23 is equipped with a clamping assembly for holding the nail core. The clamping assembly includes a sliding seat 40 fixedly connected to the inner wall of the adjusting seat 23, an extension plate 41 slidably connected to the inner wall of the sliding seat 40, and a clamping block 60 slidably connected to the bottom end of the extension plate 41 for clamping and fixing. A reset spring 42 for resetting is installed on the opposite wall surfaces of the extension plate 41 and the sliding seat 40. A sliding groove is opened at the bottom of the extension plate 41. A sliding block 61 is fixedly connected to the top of the clamping block 60 and slidably connected to the inner wall of the sliding groove. An adjusting assembly is installed on the extension plate 41 to adjust the clamping pressure of the clamping block 60 according to the diameter of the nail core. The clamping pressure of the nail core is adjusted by the adjusting assembly to avoid the pressure being too low to pull it, and to avoid the pressure being too high to cause the nail core to break prematurely, which would affect the riveting effect.

[0030] The inner wall of the adjusting seat 23 is equipped with a driving assembly for driving the clamping block 60 and the extension plate 41 to slide. The driving assembly drives the sliding block 61 on the clamping block 60 to slide closer to each other in the sliding groove at the bottom of the extension plate 41 to clamp and fix the nail core, and drives the extension plate 41 to slide in the sliding seat 40 to pull the nail core for riveting.

[0031] Referring to Figure 7, a plurality of linearly arranged fastening teeth 62 are fixedly connected to the clamping block 60 on the side near the axis of the adjusting seat 23. The cross-section of the fastening teeth 62 is trapezoidal. The cross-section of the other side of the clamping block 60 is inclined. An adjusting groove is provided on the inner wall of the clamping block 60. A plurality of linearly arranged through grooves 63 are provided on one side of the adjusting groove and extend to the outer wall of the clamping block 60. A limiting plate 76 for bearing pressure is slidably connected in the through grooves 63. When the clamping blocks 60 are close to each other, the nail core can be clamped and fixed by the fastening teeth 62 on the clamping block 60.

[0032] Referring to Figure 4, the drive assembly includes a second electric lifting rod 30, a connecting plate 31, and a compression ring 32. The second electric lifting rod 30 is installed at the top axis position of the adjusting seat 23. The connecting plate 31 is fixedly connected to the bottom axis position of the second electric lifting rod 30. A first connecting rod 33 is fixedly connected to the opposite wall surfaces of the connecting plate 31 and the compression ring 32. The inner ring cross-section of the compression ring 32 is inclined and sleeved on the outer wall of the clamping block 60. When riveting is required, the second electric lifting rod 30 is activated to drive the connecting plate 31 to rise and fall, and the connecting plate 31 can be driven by the first connecting rod 33. The moving compression ring 32 moves, and the compression ring 32 can squeeze through the inclined part of the side wall of the clamping block 60, which in turn drives the clamping block 60 to slide closer to each other in the sliding groove through the sliding block 61 to clamp and fix the nail core. When the compression ring 32 moves to the limiting plate 76, the compression of the limiting plate 76 by the compression ring 32 can drive the clamping block 60 to move, and then the clamping block 60 drives the extension plate 41 to slide in the sliding seat 40. The clamping of the nail core by the fastening teeth 62 drives the nail core to move. The movement of the nail core can drive the rivet body to lock, and the nail core can be removed by pulling and breaking.

[0033] Referring to Figures 7 and 8, the adjustment assembly includes a fixed base 70 and a connecting column 72. The fixed base 70 is fixedly connected to the inner wall of the adjustment groove on the clamping block 60. A first piston plate 71 is fixedly connected to the bottom end of the connecting column 72. The first piston plate 71 is slidably connected to the inner wall of the fixed base 70. A through air cavity 73 is opened at the top of the connecting column 72. A limiting plate 76 is slidably connected to the inner wall of the air cavity 73 on the connecting column 72.

[0034] Referring to Figures 6 and 7, a ring-shaped connecting ring 50 is fixedly connected to the outer wall of the sliding seat 40. Multiple first sleeves 51 arranged in a circular pattern are installed on the inner wall of the connecting ring 50. The inner wall of the first sleeve 51 is connected to a first gas supply pipe 52. The other end of the first gas supply pipe 52 passes through the extension plate 41, the sliding block 61, and the clamping block 60, and is connected between the fixed seat 70 and the first piston plate 71. The extension plate 41 has a slot 43 on the side near the connecting ring 50. The first gas supply pipe 52 is slidably connected to the inner wall of the slot 43. When the gas in the first sleeve 51 changes, the gas can be transported to the space between the fixed seat 70 and the first piston plate 71 through the first gas supply pipe 52. The gas can then drive the first piston plate 71 to slide within the fixed seat 70, thereby driving the connecting column 72 and the limiting plate 76 on it to move and adjust the position of the limiting plate 76.

[0035] Referring to Figures 7 and 8, a second sleeve 80 is fixedly connected to the bottom of the outer wall of the clamping block 60. The tail end of the second sleeve 80 is flush with the tail end of the fastening tooth 62, and a second air supply pipe 81 is connected inside the second sleeve 80. The other end of the second air supply pipe 81 passes through the fixed seat 70 and the first piston plate 71 and connects to the inner wall of the air chamber 73. The air chamber 73 is L-shaped, and a second piston plate 74 and a third piston plate 75 are slidably connected to the inner wall of the air chamber 73. A limiting plate 76 is fixedly connected to the outer wall of one side of the third piston plate 75. When the gas in the second sleeve 80 changes, the gas can be delivered to the air chamber 73 through the second air supply pipe 81. Then, the gas drives the second piston plate 74 to move. The movement of the second piston plate 74 can change the gas between the second piston plate 74 and the third piston plate 75, which can drive the third piston plate 75 to move and thus drive the limiting plate 76 to move.

[0036] Referring to Figure 9, a fourth piston plate 84 is slidably connected to the inner walls of both the first sleeve 51 and the second sleeve 80. A second connecting rod 82 is fixedly connected to one end of the fourth piston plate 84 at its axial position, and a pressure-bearing ball 83 is fixedly connected to the other end of the second connecting rod 82. When the nail core enters the adjusting seat 23, the nail core can squeeze the pressure-bearing ball 83 on the first sleeve 51, causing the fourth piston plate 84 to slide inside the second sleeve 80, thereby squeezing the gas and transporting it through the first gas supply pipe 52. The clamping block 60 moves closer to the nail core, at which point the nail core can squeeze the pressure-bearing ball 83 on the second sleeve 80, squeezing the gas through the fourth piston plate 84, and then transporting the gas through the second gas supply pipe 81.

[0037] The working principle of this utility model is as follows: When riveting is required, the workpiece is placed on the top of the placement table 12. The drive motor 11 is started to drive the first electric lifting rod 21 to rise and fall. Then, the connecting plate 20, adjusting seat 23, connecting seat 24 and guide seat 25 move down to insert the rivet core into the adjusting seat 23. At this time, the rivet core can squeeze the pressure ball 83 on the upper rod of the first sleeve 51, causing the fourth piston plate 84 to move. The compressed gas can be transported to the fixed seat 70 through the first gas supply pipe 52 to squeeze the first piston plate 71. The first piston plate 71 is squeezed and slides in the fixed seat 70, driving the connecting column 72 to move synchronously. The movement of the connecting column 72 can drive the movement of the limiting plate 76 to adjust the position of the limiting plate 76. Then, the second electric lifting rod 30 is turned on to drive the connecting plate 31 to move upward. The connecting plate 31 can then be driven by the first connecting rod 33. When the compression ring 32 moves upward, it can compress the clamping block 60, causing the clamping blocks 60 to move closer to each other and clamp the nail core through the fastening teeth 62. At this time, the nail core can compress the pressure ball 83 on the second sleeve 80 to be flush with the fastening teeth 62. The pressure ball 83 can then drive the fourth piston plate 84 to move through the second connecting rod 82 to compress the gas and deliver it to the gas chamber 73 through the second gas supply pipe 81. The gas can then be compressed by the compression of the second piston plate 74 to compress the third piston plate 75. The compression of the third piston plate 75 can then drive the limiting plate 76 to move out of the through groove 63 and extend to the outer wall of the clamping block 60, thereby blocking the compression ring 32 and limiting the position of the compression ring 32 on the clamping block 60. The compression ring 32 compresses the clamping block 60 by compressing the limiting plate 76, and drives the nail core clamped on the fastening teeth 62 to move upward for riveting.

[0038] After riveting is completed, the workpiece is transferred to the unloading track 14 by the robotic arm 13 for unloading.

[0039] When this utility model is in use, the position of the limiting plate 76 can be adjusted according to the diameter of the rivet core by the set adjustment component, and the position of the extrusion ring 32 on the clamping block 60 can be adjusted accordingly. This can adjust the clamping pressure of the fastening teeth 62 on the clamping block 60 on the rivet core, avoiding excessive pressure that causes the rivet core to break prematurely, and insufficient pressure that prevents the rivet core from driving the rivet to rivet, thus affecting the riveting effect.

[0040] With the set drive component, the fastening teeth 62 on the clamping block 60 can be driven to move closer to each other to clamp and fix the nail core and pull it to rivet by simply raising and lowering the connecting plate 31, without the need for steps, thus improving the efficiency of riveting.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
