[0049] Figure 1 FIG. 2 shows a schematic diagram of the structure of a two-dimensional pipe segment pairing system according to an embodiment of the present application. Figure 1 As shown, the two-dimensional pipe segment assembly system provided in this embodiment includes an assembly base 1, an assembly head 2, a second assembly chuck 3 and an assembly tailstock 4.

[0051] In one embodiment, the first clamping mechanism 21 and the second clamping mechanism 30 can clamp any one or more of a straight pipe, a bent pipe, a flange or a flange, and the third clamping mechanism 40 can clamp a flange.

[0052] It can be understood that by setting the first group chuck 20, the second group chuck 3 and the group tail frame 4, various grouping scenarios of one-dimensional and two-dimensional pipe segments can be realized, such as flange / flange-elbow grouping, double flange grouping, flange / flange-straight pipe grouping, elbow-straight pipe grouping, etc.

[0053] In the present application, the assembly head 2 is connected to the first transmission mechanism 11, so that it can be movably arranged on the assembly base 1 in the first direction. The first transmission mechanism 11 includes a first driving component 12, a first transmission rod 111 and a first guide component 112. The first transmission rod 111 connects the first driving component 12 and the assembly head 2. The assembly head 2 is arranged on the assembly base 1 through the first guide component 112. The first driving component 12 drives the first transmission rod 111 to drive the assembly head 2 to move relative to the assembly base 1 along the first direction.

[0054] Figure 2 FIG. 2 shows a schematic diagram of the structure of the first transmission mechanism shown in an embodiment of the present application. Figure 2As shown, in this embodiment, the first drive assembly 12 includes a servo motor 121 and a planetary reducer 122 connected thereto, the first transmission rod 111 is a ball screw, and the first guide assembly 112 is a linear guide. The ball screw is connected to the bottom of the assembly head 2 through a screw pair, and the two sides of the assembly head 2 are respectively connected to the linear guide through the first sliding member 100. By using a servo motor in conjunction with a reducer to drive the ball screw to rotate, the assembly head 2 connected thereto can be moved on the linear guide and provide high-precision position control, which is suitable for assembly scenarios that require high dynamic response and precise control.

[0055] In other embodiments, the first driving assembly 12 may also be a gear reduction motor, a belt reduction motor or other driving mechanisms, which are selected based on the weight of the assembly head 2 and the required accuracy.

[0056] In one embodiment, the first transmission rod 111 may also be a transmission structure such as a trapezoidal screw, a gear rack, a transmission rod, a transmission chain, etc.

[0057] like Figure 2 As shown, the assembly base 1 has a working space, which includes a first area 101 and a second area 102 distributed up and down along the second direction, wherein the first area 101 is arranged close to the ground, and the second area 102 is arranged away from the ground. The first guide assembly 112 can be arranged in the second area 102, and the assembly head 2 and the assembly tailstock 4 can be movably arranged on the first guide assembly 112 in the second area 102, and at the same time, the second assembly chuck 3 is arranged in the first area 101. This arrangement can prevent the second assembly chuck 3 from interfering with the assembly head 2 and / or the assembly tailstock 4 moving along the first direction on the first guide assembly 112, and at the same time, the workpiece on the gravity plane (second direction) can have a lower center of gravity, which helps to maintain stability when assembling the workpiece, reduce the safety risks caused by the unstable center of gravity of the workpiece, and is particularly suitable for the assembly of thick and heavy pipe sections, ensuring the safety of the operation process.

[0058] Specifically, the assembly base 1 includes a first plate 13 and a second plate 14 arranged opposite to each other along the first direction, and a spacing area adapted to the size of the assembly head 2, the second chuck, and the assembly tailstock 4 is provided between the first plate 13 and the second plate 14, thereby defining the working space.

[0059] In this embodiment, linear guide rails of the first guide assembly 112 are installed on the end surfaces of the first plate body 13 and the second plate body 14 away from the ground, and the assembly head 2 is then set on the first guide assembly 112 through the first sliding member 100.

[0060] As an example but not a limitation, the first sliding member 100 can be an object that can be used to slide on a linear guide rail, such as a guide rail pair, a pulley or a ball. In one embodiment, the assembly head 2 is movably connected to the linear guide rail by a guide rail pair, and the guide rail pair is provided with a groove, and the groove is adapted to the linear guide rail.

[0061] Figure 3 FIG. 1 shows a schematic diagram of the structure of the head assembly shown in an embodiment of the present application. Figure 3 As shown, the assembly head 2 further includes a frame 22 and a first rotary mechanism 23, a chuck lifting mechanism 24 and a chuck translation mechanism 25, wherein the first assembly chuck 20 and the first rotary mechanism 23 are arranged on the frame 22, and the first rotary mechanism 23 is connected to the first assembly chuck 20 to drive the first assembly chuck 20 to drive the first clamping mechanism 21 to rotate. The chuck lifting mechanism 24 and the chuck translation mechanism 25 are arranged on the frame 22, and the chuck lifting mechanism 24 and the chuck translation mechanism 25 are connected to the first assembly chuck 20 to respectively realize the movement of the first assembly chuck 20 in the second direction and the third direction.

[0062] Specifically, the frame 22 is provided with a first mounting plate 221 and a second mounting plate 222, the first set of chucks 20 are mounted on the second mounting plate 222, the chuck lifting mechanism 24 includes a chuck lifting motor 241 and a chuck lifting guide rail 242 arranged between the first mounting plate 221 and the second mounting plate 222 along the second direction, the second mounting plate 222 is movably connected to the first mounting plate 221 in the second direction through the chuck lifting slide 240, and the chuck lifting motor 241 is detachably connected to the second mounting plate 222 through the lifting transmission rod 243 and the lifting fixed connection member 244. In this embodiment, the chuck lifting motor 241 drives the lifting transmission rod 243 to rotate, so that it drives the lifting fixed connection member 244 and the second mounting plate 222 to move along the chuck lifting guide rail 242 in the second direction, thereby completing the movement of the first set of chucks 20 in the second direction (gravity direction).

[0063] As an example but not a limitation, the chuck lifting slide 240 can be an object that can be used to slide on a linear guide rail, such as a guide rail pair, a pulley or a ball. In one embodiment, the assembly head 2 is movably connected to the linear guide rail by a guide rail pair, and the chuck lifting slide 240 is provided with a groove, which is adapted to the linear guide rail.

[0064] As an example but not a limitation, the lifting transmission rod 243 can be a screw rod, and the screw rod and the lifting fixed connecting member 244 are connected by a screw rod pair sleeved on the screw rod.

[0065] The first set of chucks 20 also includes a swivel mechanism 26, which is installed on a side of the second mounting plate 222 away from the first mounting plate 221. The chuck translation mechanism 25 includes a chuck translation drive assembly 251 and a chuck translation guide rail 252 arranged on the second mounting plate 222 along the third direction. The first set of chucks 20 is movably connected to the second mounting plate 222 in the third direction through a chuck translation slide 253, and the chuck translation drive assembly 251 is detachably connected to the first set of chucks 20 through a translation transmission rod 254 and a translation fixed connection 255. In this embodiment, the chuck translation drive assembly 251 drives the translation transmission rod 254 to move in the third direction, thereby completing the movement of the first set of chucks 20 in the third direction. The third direction is perpendicular to the first direction and the second direction.

[0066] As an example but not a limitation, the translation transmission rod 254 may be a screw rod, the chuck translation driving assembly 251 may be an operating wheel connected to the translation transmission rod 254 and disposed outside the frame 22, and the first set of chucks 20 is connected to the translation transmission rod 254 via a screw rod pair 253. By manually rotating the operating wheel, the first set of chucks 20 can be moved in the third direction along the chuck translation guide rail 252.

[0067] In some embodiments, the first group of chucks 20 can be a conventional machining chuck structure, which is a prior art and is not described in detail here. The first group of chucks 20 are driven by a chuck clamping mechanism 210. As a demonstration and not limitation, the chuck clamping mechanism 210 can include a motor reducer, a chain sprocket, a torque limiter and a chuck drive shaft, etc. First, the motor is used as a power source to increase the torque through the reducer, and the drive chain and sprocket transmit the rotational motion to the chuck drive shaft. In some embodiments, the spiral groove or gear structure on the chuck drive shaft interacts with the claws to push the claws to move inward to clamp the workpiece. It is understandable that in some embodiments, to ensure safe operation, the chuck clamping mechanism 210 is also equipped with a torque limiter, which automatically disconnects the chain from the drive shaft when the clamping force exceeds a preset value to prevent damage. When it is necessary to release the workpiece, the motor is reversed and the drive shaft is rotated in the opposite direction, and the claws move outward to release the workpiece. The entire process takes into account the precise control of the clamping force, the adaptability of the workpiece, and the safety of the operation, thereby ensuring the efficient and stable operation of the chuck clamping mechanism 210 .

[0068] In some embodiments, the slewing mechanism 26 may be a slewing bearing, and the chuck is mounted thereon. Through the cooperation of the inner and outer rings and the intervention of rolling elements, the rotational movement of the chuck on the vertical axis is realized. As a demonstration but not limitation, the inner ring is connected to the chuck or the mechanical component, and the outer ring is fixed to the base or the bracket. Rolling elements such as balls or rollers roll between the inner and outer rings to reduce friction and transfer loads. The first slewing mechanism 23 may be a motor or other power source, which drives the slewing mechanism 26 to drive the chuck to rotate through transmission methods such as gears and belts. In some other embodiments, the chuck can be accurately positioned or fixed at a specific angle by setting a positioning and locking mechanism to meet the diverse needs of pipe segment pairing.

Figure 1 and Figure 4 The two-dimensional pipe segment assembly system also includes at least one supporting device 5. In this embodiment, two supporting devices 5 are slidably arranged on the first guide assembly 112 through a second sliding member 50, and the supporting device 5 is arranged in the second area 102 between the first assembly chuck 20 and the assembly tail frame 4, which can also avoid interference with the second assembly chuck 3 during movement.

In this embodiment, the second sliding member 50 is a guide rail pair, and the guide rail pair 50 is provided with a groove, and the groove is adapted to the linear guide rail.

[0071] As an example but not a limitation, the second sliding member 50 may also be an object such as a pulley or a ball that can be used to slide on a linear guide rail.

[0073] As an example but not a limitation, the third sliding member 42 may also be an object such as a pulley or a ball that can be used to slide on a linear guide rail.

[0074] It is understandable that the second set of chucks 3 of the present application can adopt a structure similar to that of the first set of chucks 20, but because it is arranged in the first area 101 of the set base 1 and is used to clamp the pipe fixed in the second direction, there is no need to set the chuck lifting mechanism 24 and the chuck translation mechanism 25, and only the second clamping mechanism 30 and the second rotary mechanism are required. Similar to the relevant structure of the first set of chucks 20 in the aforementioned embodiment, the second rotary mechanism connects and drives the second clamping mechanism 30 on the second set of chucks 3 to rotate, and then in response to the user's operation or instruction, the second clamping mechanism 30 clamps or releases the workpiece.
