Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, specifically to a pipe assembly equipment and method. Background Technology

[0002] In modern industrial production, pipe processing and assembly are indispensable processes in many industries, especially in petroleum, chemical, construction, and machinery manufacturing. Existing pipe structures typically consist of an inner and an outer pipe. One end of the outer pipe has a threaded section for connecting and securing various components, while the inner pipe is responsible for transporting the medium. During assembly, the threaded section of the outer pipe is tightened using a nut, while the inner pipe is positioned and supported using fasteners such as rings. However, current technological development in this field still faces certain limitations, mainly in the following aspects: Currently, there is no dedicated equipment for tightening the nuts on the external pipe threads and attaching the inner pipe rings, resulting in low assembly efficiency. This limitation is particularly pronounced when facing large-scale production demands. Especially due to factors such as operator skill level, physical condition, and subjective judgment, inconsistencies may arise in the tightening force of the nuts and the position of the inner pipe rings. This directly affects the sealing and reliability of the pipe connections, thus impacting the safe operation of the entire system. Furthermore, significant differences in the dimensions and shapes of nuts and pipes across different operating environments further exacerbate the impact on assembly quality.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0023] Example 1: See Figures 1 to 3As shown, this embodiment provides a pipe assembly device, which includes a nut tightening mechanism 200. The nut tightening mechanism 200 includes a pipe rotation drive assembly 210, a nut feeding assembly 220, and a nut transmission assembly 230. The pipe rotation drive assembly 210 is connected to the outer pipe to be processed to drive the outer pipe to be processed to rotate around its central axis. The nut feeding assembly 220 includes a first frame 222, at least two transmission plates 221, and a first feeding assembly 223. The transmission plates 221 are connected to the first frame 222 and extend along a first direction X. At least two transmission plates 221 are arranged parallel to each other along a second direction Y and move along the second direction Y respectively. The space between two adjacent transmission plates 221 is a feeding channel. The nut to be assembled is supported on the feeding channel. The first feeding assembly... Component 223 is positioned toward the feeding channel and moves along the first direction X to move the nut along the feeding channel; the nut transmission component 230 includes a second frame 231, a second slide 233, and a docking post 237. The second frame 231 is positioned between the nut tightening mechanism 200 and the threaded end of the outer tube to be processed. The second slide 233 is slidably connected to the second frame 231 along the third direction Z. The docking post 237 is connected to the second slide 233 and is extended toward the outer tube to be processed. The nut transmission component 230 drives the nut output by the nut tightening mechanism 200 to move, so that the threaded end of the outer tube to be processed passes through the nut, and the nut is connected to the threaded end of the outer tube to be processed by the tube rotation drive component 210.

[0024] The pipe assembly equipment described in this embodiment achieves a complete automated process of nut feeding, transmission, docking, and rotational connection through the high degree of cooperation between the nut tightening mechanism 200 and the nut transmission component 230. At the same time, the reasonable layout between the above mechanisms can achieve a high-efficiency and high-precision processing process within a limited space. Compared with the conventional assembly methods at present, this application has significant advantages such as high degree of automation, ease of operation, wide applicability, high yield, and high processing efficiency.

[0025] It should be noted that, for ease of description, in this embodiment, the length direction of the pipe assembly equipment is defined as the first direction X, the width direction of the equipment is defined as the second direction Y, and the height direction of the equipment is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0026] See Figures 1 to 3As shown, this embodiment also includes a hanging ring mechanism 300, so that the device can also perform hanging ring assembly on the inner tube of the pipe to be processed. Furthermore, in this embodiment, the pipe body is located below the screwing nut mechanism 200 and the hanging ring mechanism 300. The screwing nut mechanism 200 and the hanging ring mechanism 300 are connected and arranged along the second direction Y, thereby reducing the overall volume of the device.

[0027] Further, see Figure 4 and Figure 5 As shown, this embodiment also includes a pipe support mechanism 100, which includes a support platform 110 and at least one support component 120. At least one support component 120 is slidably connected to the support platform 110 along a first direction X, and the pipe to be processed is supported on the support component 120. The support platform 110 provides an installation platform for the support component 120. In this embodiment, one support component 120 is provided to support the middle of the pipe, preventing collapse or bending damage in the middle of the pipe. In different embodiments, operators can set one or more support components 120 at different positions according to factors such as the actual length, weight, and material of the pipe being processed; this invention does not impose specific limitations on this. Furthermore, the support assembly 120 includes a frame 121, a lifting plate 126, and at least two support claws 127. The frame 121 is fixed on the support platform 110. The lifting plate 126 is slidably connected to the frame 121 along the third direction Z. The support claws 127 are disposed at the top of the lifting plate 126 and move synchronously with the lifting plate 126. The tube to be processed is supported between at least two of the support claws 127. Furthermore, in order to improve the control precision of the lifting plate 126 and reduce the volume of the support assembly 120, the support assembly 120 in this embodiment also includes a rotary motor 122, a connecting shaft 123, a gear 124, and a rack 125. The two ends of the connecting shaft 123 are connected to the frame 121, and one end is connected to the rotary motor 122. The gear 124 is sleeved in the middle of the connecting shaft 123. The rack 125 extends along the third direction Z and is disposed on the lifting plate 126. The gear 124 and the rack 125 mesh with each other to drive the lifting plate 126 to move up and down.

[0028] In this embodiment, the pipe rotation drive assembly 210 provides driving force for the rotation of the pipe to be processed. It includes a rotation driver 211 and a connecting box 212. The connecting box 212 is connected to the working end of the rotation driver 211. The chassis of the pipe to be processed is fastened inside the connecting box 212 to drive the pipe to be processed to rotate around its central axis. Specifically, in this embodiment, the chassis is a square disc-shaped element. Correspondingly, the connecting box 212 has a square accommodating space inside. This can support and fix the pipe while preventing unexpected rotation, thereby further improving its assembly accuracy. In different embodiments, the connecting box 212 can be adaptively adjusted according to the shape of the actual pipe chassis. This invention does not impose specific limitations on this.

[0029] See Figure 6 As shown, in this embodiment, the nut feeding assembly 220 includes two transmission plates 221 spaced apart along the second direction Y. The two transmission plates 221 support the nuts to be assembled, and the two transmission plates 221 can move relatively closer / away along the second direction Y, so that this application can be applied to nuts of different sizes and models to be assembled. Similarly, to improve its working efficiency, multiple transmission plates 221 can be set in different embodiments to create multiple feeding channels. Further, the first frame 222 is provided with a feeding rail 2221 extending along the first direction X and multiple adjusting rails 2222 extending along the second direction Y. The transmission plates 221 are slidably connected to the adjusting rails 2222 to adjust the width of the feeding channel, and the first feeding assembly 223 is slidably connected to the feeding rail 2221.

[0030] Specifically, see Figure 7 As shown, the first material feeding assembly 223 in this embodiment includes a first slide 2231, a first lifting module 2232, a lifting driver 2234, and a paddle 2233. The first slide 2231 is slidably connected to the first frame 222. The first lifting module 2232 is connected to the first slide 2231 and extends along the third direction Z. The lifting driver 2234 is disposed on the first slide 2231. The paddle 2233 is connected to the working end of the lifting driver 2234 so that the lifting driver 2234 moves closer to / away from the feeding channel along the third direction Z, thereby realizing the paddle movement of the nut to be assembled.

[0031] See Figure 8 and Figure 9As shown, the nut transmission assembly 230 includes a second lifting module 232, a second slide 233, a telescopic guide rail 234, and a telescopic frame 238. The second lifting module 232 is connected to the second frame 231 and extends along the third direction Z. One side of the second slide 233 is slidably connected to the second lifting module 232, and the other side is connected to the telescopic guide rail 234. The telescopic guide rail 234 extends toward the tube to be processed. The telescopic frame 238 is connected to the telescopic guide rail 234. The docking post 237 is disposed on the side of the telescopic frame 238 facing the tube to be processed. Based on this, the docking post 237 in this embodiment can move in the first direction X and the third direction Z, thereby achieving high-precision docking with the nut feeding assembly 220 and the tube to be assembled.

[0032] Furthermore, since it is difficult to achieve coaxial movement between the docking post 237 and the pipe to be processed, in order to ensure that the threaded end can pass into the nut, the nut transmission assembly 230 in this embodiment also includes a floating plate 235 and at least one elastic element 236. One end of the elastic element 236 is connected to the telescopic frame 238, and the other end is connected to the floating plate 235. The docking post 237 is connected to the side of the floating plate 235 facing the pipe to be processed. Based on this structural arrangement, when the nut and the pipe to be processed are connected, the floating plate 235 can adjust its actual docking angle with the pipe through the force deformation of the corresponding elastic element 236, thereby improving docking efficiency and effect. Specifically, the elastic element 236 in this embodiment is preferably a rubber columnar element. In different embodiments, it can also be set as a spring, a sheet, or other structure, or made of silicone or other elastic materials. This invention does not impose specific limitations on this.

[0033] See Figure 10 As shown, in this embodiment, the hanging ring mechanism 300 includes a third frame 310, a feeding rod 320, and a second material-pushing assembly 330. The third frame 310 and the first frame 222 are arranged along the second direction Y. The feeding rod 320 and the second material-pushing assembly 330 are respectively connected to the first frame 222. The feeding rod 320 extends along the first direction X, and the hanging ring to be assembled is suspended on the feeding rod 320. The second material-pushing assembly 330 slides along the first direction X to move the hanging ring along the feeding rod 320. In this embodiment, the second material-pushing assembly 330 has the same structural configuration as the first material-pushing assembly 223. It is used to move the hanging ring on the feeding rod 320 to the inner ring of the pipe to be assembled. The pipe to be processed is connected to the feeding rod 320 through an external mobile device, which can be a robotic arm, a crane, or a handling robot, etc.

[0034] This embodiment also includes a control system. During actual production and processing, operators can adjust the above structure in real time through the control system, thereby improving the flexibility of the equipment. Parameters can also be preset through the control system, thereby improving the automation level of the equipment.

[0035] Example 2: This example provides a pipe assembly method, which uses the pipe assembly equipment described in Example 1 to assemble pipes, and includes: Step S1: Load the nuts to be assembled through the loading channel; further, in this embodiment, the width of the loading channel is adjusted to match the nut model.

[0036] Step S2: The nut to be assembled is received at the discharge end of the feeding channel, and the threaded end of the outer tube to be processed is inserted into the nut to be assembled. Further, in this embodiment, the nut is moved to the output end of the feeding channel by the feeding component. After the nut is received by the nut, the nut transmission component 230 moves it to the threaded part of the tube to be processed, so that the threaded end of the outer tube to be processed is inserted into the nut to be assembled. During this process, it can be finely adjusted by the floating of the docking post 237 to ensure that the central axis of the nut coincides with the central axis of the tube to be processed.

[0037] Step S3: Rotate the outer tube to be processed around its central axis while simultaneously pushing the nut to connect it to the threaded end, thus completing the tube assembly process. Further, in this embodiment, the tube to be processed is driven to rotate by the tube rotation drive assembly 210, while the nut is pushed by the nut transmission assembly 230 to connect the nut to the threaded end.

[0038] This embodiment also includes step S4, which involves moving the pipe to be processed using an external handling component. The external handling device brings the inner tube of the pipe to be processed close to the hanging ring to be assembled, and moves the hanging ring onto the inner tube to complete the assembly process between the hanging ring and the inner tube.

[0039] In summary, the pipe assembly equipment and method described in this invention achieves a complete automated process of nut feeding, transmission, docking, and rotational connection through the high degree of cooperation between the nut tightening mechanism 200 and the nut transmission assembly 230. At the same time, the reasonable layout of the above-mentioned mechanisms can achieve a high-efficiency and high-precision processing process within a limited space. Compared with the conventional assembly methods at present, this application has significant advantages such as high degree of automation, ease of operation, wide applicability, high yield, and high processing efficiency.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

Step S3 specifically involves using the tube rotation drive assembly to drive the tube to be processed to rotate, while the nut transmission assembly pushes the nut to connect the nut with the threaded end.
