[0002] Currently, the structure of pipe and flange splicing positioning devices is usually fixed. That is, the positions of the structures used to clamp the flange in the splicing positioning device are fixed. It can only be used for the assembly of pipes and flanges of specific sizes and angles. When assembling pipes and flanges of different sizes and angles, multiple different splicing positioning devices need to be designed, which is costly. Utility Model Content

[0003] The purpose of this disclosure is to provide a pipe flange splicing positioning device that is applicable to the assembly of pipes and flanges of various sizes and angles, and can improve the level of automation in welding.

[0004] This disclosure provides a pipe flange splice positioning device, including: Base; A lateral movement assembly, which is disposed on the base and is capable of moving laterally relative to the base; A longitudinal movement component, which is disposed on the base and is capable of moving longitudinally relative to the base; A lifting assembly is disposed on the transverse assembly and is capable of vertically lifting relative to the base; Both the longitudinal movement assembly and the lifting assembly are provided with clamping assemblies for clamping flanges; wherein the flange clamped by the clamping assembly is aligned with at least two ends in the same pipeline.

[0005] In one exemplary embodiment of this disclosure, there is an intersection between the movement trajectory of the lateral component and the movement trajectory of the longitudinal component.

[0006] In one exemplary embodiment of this disclosure, the pipe flange splice positioning device includes two transverse moving components, which are arranged laterally on the base, and the clamping components on the two transverse moving components are arranged opposite to each other.

[0007] In one exemplary embodiment of this disclosure, the base is provided with a plurality of driving components, wherein two of the driving components are connected to two of the transverse moving components in a one-to-one correspondence, so as to drive the corresponding transverse moving components to move laterally.

[0008] In an exemplary embodiment of this disclosure, the base is provided with a transverse sliding track extending laterally and a longitudinal sliding track extending longitudinally. The transverse sliding component is disposed on the transverse sliding track and is slidable along the extension direction of the transverse sliding track, and the longitudinal sliding component is disposed on the longitudinal sliding track and is slidable along the extension direction of the longitudinal sliding track. The longitudinal track is erected on the top surface of the transverse track, and the two transverse components are located on opposite sides of the longitudinal track in the transverse direction.

[0009] In one exemplary embodiment of this disclosure, the clamping assembly is rotatable along its central axis.

[0010] In one exemplary embodiment of this disclosure, the clamping assembly is detachably connected to the corresponding lifting assembly and the corresponding longitudinal movement assembly.

[0011] In one exemplary embodiment of this disclosure, the lifting assembly includes a support bracket located below the corresponding clamping assembly. The inner end of the support bracket is connected to the lateral movement assembly, and the outer end of the support bracket extends in a direction away from the lateral movement assembly, such that its outer end protrudes outward from the corresponding clamping assembly.

[0012] In one exemplary embodiment of this disclosure, the outer end of the support bracket is provided with a support roller, the axis of which is perpendicular to the vertical; the support bracket is used to support the pipe.

[0013] In an exemplary embodiment of this disclosure, a support base is provided on the top surface of the longitudinal movement component, and at least two clamping components are provided on the support base, wherein at least one clamping component is located on the top surface of the support base, and at least one clamping component is installed on the side periphery of the support base.

[0014] The technical solutions provided in this disclosure have at least the following advantages: This disclosure, by setting a transverse moving component, a longitudinal moving component, and a lifting component, and setting a clamping component on the longitudinal moving component and the lifting component, allows the position of the transverse moving component, the longitudinal moving component, and the lifting component on the base to be adjusted according to the size and angle of the pipe, so that the position of the clamping component in the pipe flange splicing positioning device corresponds to the corresponding end position on the pipe. In this way, the pipe flange splicing positioning device can be applied to the assembly of pipes and flanges of various sizes and angles.

[0015] This disclosure can also pre-measure the dimensions and angles of the pipeline and select the corresponding program before welding so that the position of the clamping component in the pipeline flange splicing positioning device corresponds to the corresponding end position on the pipeline. This can improve the automation level of welding, reduce the involvement of personnel in the pipeline and flange alignment process, improve the installation accuracy of the pipeline and flange, and increase work efficiency.

[0030] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0031] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed.

[0032] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0033] like Figure 1As shown, this disclosure provides a pipe flange splicing positioning device, which may include: a base 100, a transverse moving assembly 200, a longitudinal moving assembly 300, and a lifting assembly 400. The transverse moving assembly 200 is disposed on the base 100 and is capable of moving laterally (x) relative to the base 100. The longitudinal moving assembly 300 is disposed on the base 100 and is capable of moving longitudinally (y) relative to the base 100. The lifting assembly 400 is disposed on the transverse moving assembly 200 and is capable of vertically lifting relative to the base 100. Both the longitudinal moving assembly 300 and the lifting assembly 400 are provided with clamping assemblies 500 for clamping flanges. The flange clamped by the clamping assembly 500 can be aligned with at least two ends of the same pipe.

[0034] This disclosure, by setting a transverse moving component 200, a longitudinal moving component 300, and a lifting component 400, and placing a clamping component 500 on the longitudinal moving component 300 and the lifting component 400, allows the positions of the transverse moving component 200, the longitudinal moving component 300, and the lifting component 400 on the base 100 to be adjusted according to the size and angle of the pipe, so that the position of the clamping component 500 in the pipe flange splicing positioning device corresponds to the corresponding end position on the pipe. This enables the pipe flange splicing positioning device to be applicable to the assembly of pipes and flanges of various sizes and angles.

[0035] This disclosure can also pre-measure the dimensions and angles of the pipeline and select the corresponding program before welding so that the position of the clamping component 500 in the pipeline flange splicing positioning device corresponds to the corresponding end position on the pipeline. This can improve the automation level of welding, reduce the involvement of personnel in the pipeline and flange alignment process, improve the installation accuracy of the pipeline and flange, and increase work efficiency.

[0036] Specifically, the pipe flange assembly positioning device may include a touch screen, on which different pipe programs (including dimensions, angles, etc.) are pre-set. When assembling pipes and flanges of different specifications, different pipe programs can be selected directly on the touch screen according to the pipe model. This allows the horizontal movement component 200, the vertical movement component 300, and the lifting component 400 to automatically adjust their positions on the base 100, so that the position of the clamping component 500 in the pipe flange assembly positioning device corresponds to the corresponding end position on the pipe. The program needs to consider the optimal sequence of operation actions, rationally arrange the layout of buttons, etc., and create the most suitable working environment.

[0037] It should be noted that the dimensions and angles of a pipe can refer to data such as the pipe's length, width, height, diameter, and bending angle.

[0038] The process of positioning and assembling the pipe and flange in this disclosure can be as follows: After adjusting the positions of the transverse moving assembly 200, longitudinal moving assembly 300, and lifting assembly 400 on the base 100 according to the size and angle of the pipe, the flange is manually placed on the corresponding clamping assembly 500 and tightened. Then, the flange is welded to the corresponding ends of the pipe in sequence, that is: first install the flange on one end of the pipe, then install the flange on the other end of the pipe, until the assembly between the corresponding ends of the pipe where the flange needs to be installed and the flange is completed.

[0039] The welding between the pipe and the flange can be done manually, but it is not limited to that. It can also be done by machine, depending on the actual situation.

[0040] like Figures 2 to 4 As shown, in some embodiments, a transverse track 201 is provided on the top surface of the base 100, and the transverse track 201 extends in the lateral direction x. The transverse component 200 is disposed on the transverse track 201 and is capable of moving along the extension direction of the transverse track 201.

[0041] One or more transverse tracks 201 can be provided on the base 100. The transverse tracks 201 are arranged at intervals along the longitudinal direction y to enhance the support force on the transverse component 200.

[0042] The transverse assembly 200 may include a transverse slider 202, which is mounted on the transverse track 201 and is capable of sliding along the transverse track 201.

[0043] For example, the lateral movement assembly 200 may include a plurality of lateral movement sliders 202, which are evenly spaced along the lateral x-axis to provide uniform and stable support for the lifting assembly 400.

[0044] The lateral movement assembly 200 may further include a lateral movement base plate 203, which is mounted on the top surface of the lateral movement slider 202 and is connected and fixed to the lateral movement slider 202. The lateral movement base plate 203 is used to support the lifting assembly 400 and can drive the lifting assembly 400 to move laterally along the x-axis under the action of the lateral movement slider 202.

[0045] The top surface of the transverse base plate 203 can be provided with a limiting groove. The base 100 can include a first cover plate 204. The first cover plate 204 is provided on the top surface of the transverse base plate 203. The first cover plate 204 is partially embedded in the limiting groove on the top surface of the transverse base plate 203 and is spaced apart from the transverse base plate 203. While strengthening the protection of the transverse track 201 and the transverse slider 202 and reducing the contact between the transverse track 201 and the transverse slider 202 and the outside world, it can also strengthen the limiting of the transverse base plate 203 and reduce the situation where the transverse component 200 is displaced and separates from the transverse track 201.

[0046] The lateral movement assembly 200 may include a lateral movement limiting member 205, which is disposed on the bottom surface of the lateral movement base plate 203 and its bottom surface is lower than the top surface of the lateral movement track 201, in order to improve the problem of the lateral movement assembly 200 tipping over and detaching from the lateral movement track 201.

[0047] When the base 100 includes one transverse track 201, two transverse limiting members 205 can be provided on the bottom surface of the transverse base plate 203, with the two transverse limiting members 205 located on opposite sides of the transverse track 201 in the longitudinal direction y. When the base 100 includes multiple transverse tracks 201, two transverse limiting members 205 can be provided on the bottom surface of the transverse base plate 203, with the two transverse limiting members 205 located on opposite sides of all transverse tracks 201 in the longitudinal direction y.

[0048] The base 100 is provided with multiple drive components, which can be used to drive the corresponding transverse component 200 to move along the horizontal x-axis, or drive the corresponding longitudinal component 300 to move along the vertical y-axis, or drive the corresponding lifting component 400 to move along the vertical z-axis.

[0049] The drive assembly that moves the transverse component 200 along the transverse x-axis is defined as the transverse drive assembly. The transverse drive assembly may include a first lead screw 206, a transverse screw connector 207, and a first motor 208. The first lead screw 206 is disposed on the top surface of the base 100 and extends along the transverse x-axis. When the base 100 has multiple transverse tracks 201, the first lead screw 206 may be located in the middle of the multiple transverse tracks 201. The transverse screw connector 207 is sleeved on the outer periphery of the first lead screw 206 and threadedly connected to the first lead screw 206. The top surface of the transverse screw connector 207 is connected to the transverse assembly 200; specifically, the top surface of the transverse screw connector 207 may be connected to the bottom surface of the transverse base plate 203. The first motor 208 can be disposed at the end of the first lead screw 206 to drive the first lead screw 206 to rotate and drive the transverse screw connector 207 to move relative to the first lead screw 206 in the transverse x direction, thereby driving the transverse assembly 200 to move in the transverse x direction.

[0050] like Figures 5 to 7 In some embodiments, a longitudinal track 301 is provided on the top surface of the base 100, and the longitudinal track 301 extends in the longitudinal direction y. The longitudinal movement component 300 is disposed on the longitudinal track 301 and is capable of moving along the extension direction of the longitudinal track 301.

[0051] One or more longitudinal tracks 301 may be provided on the base 100. The longitudinal tracks 301 are arranged at intervals along the transverse x-axis to enhance the support for the longitudinal movement component 300.

[0052] The longitudinal movement assembly 300 may include a longitudinal movement slider 302, which is mounted on the longitudinal movement track 301 and is capable of sliding along the longitudinal movement track 301.

[0053] For example, the longitudinal movement assembly 300 may include a plurality of longitudinal movement sliders 302, which are evenly spaced along the longitudinal direction y to provide uniform and stable support for the lifting assembly 400.

[0054] The longitudinal movement assembly 300 may further include a longitudinal movement base plate 303, which is mounted on the top surface of the longitudinal movement slider 302 and is connected and fixed to the longitudinal movement slider 302. The longitudinal movement base plate 303 is used to support the clamping assembly 500 disposed thereon, and can drive the corresponding clamping assembly 500 to move longitudinally along the y-axis under the action of the longitudinal movement slider 302.

[0055] The top surface of the longitudinal base plate 303 can be provided with a limiting groove. The base 100 can include a second cover plate 304. The second cover plate 304 is provided on the top surface of the longitudinal base plate 303. The second cover plate 304 is partially embedded in the limiting groove on the top surface of the longitudinal base plate 303 and is spaced apart from the longitudinal base plate 303. While strengthening the protection of the longitudinal rail 301 and the longitudinal slider 302 and reducing the contact between the longitudinal rail 301 and the longitudinal slider 302 and the outside world, it can also strengthen the limiting of the longitudinal base plate 303 and reduce the situation where the longitudinal component 300 is displaced and separates from the longitudinal rail 301.

[0056] The longitudinal movement assembly 300 may include a longitudinal movement limiting member 305, which is disposed on the bottom surface of the longitudinal movement base plate 303 and its bottom surface is lower than the top surface of the longitudinal movement track 301, in order to improve the problem of the longitudinal movement assembly 300 tilting and detaching from the longitudinal movement track 301.

[0057] When the base 100 includes one longitudinal track 301, two longitudinal movement limiting members 305 can be provided on the bottom surface of the longitudinal movement base plate 303, with the two longitudinal movement limiting members 305 located on opposite sides of the longitudinal track 301 in the longitudinal direction y. When the base 100 includes multiple longitudinal tracks 301, two longitudinal movement limiting members 305 can be provided on the bottom surface of the longitudinal movement base plate 303, with the two longitudinal movement limiting members 305 located on opposite sides of all the longitudinal tracks 301 in the longitudinal direction y.

[0058] The driving component that drives the longitudinal traverse assembly 300 to move along the longitudinal direction y is defined as the longitudinal traverse drive assembly. The longitudinal traverse drive assembly may include a second lead screw 306, a longitudinal traverse screw connector 307, and a second motor 308. The second lead screw 306 is disposed on the top surface of the base 100 and extends along the longitudinal direction y. When the base 100 is provided with multiple longitudinal traverse tracks 301, the second lead screw 306 may be located in the middle of the multiple longitudinal traverse tracks 301. The longitudinal traverse screw connector 307 is sleeved on the outer periphery of the second lead screw 306 and is threadedly connected to the second lead screw 306. The top surface of the longitudinal traverse screw connector 307 is connected to the longitudinal traverse assembly 300. Specifically, the top surface of the longitudinal traverse screw connector 307 may be connected to the bottom surface of the longitudinal traverse base plate 303. The second motor 308 can be disposed at the end of the second lead screw 306 to drive the second lead screw 306 to rotate and drive the longitudinal sliding screw 307 to move relative to the second lead screw 306 along the longitudinal y direction, thereby driving the longitudinal sliding assembly 300 to move along the longitudinal y direction.

[0059] In some embodiments, a support base 309 may be provided on the top surface of the longitudinal movement assembly 300, and a clamping assembly 500 may be provided on the support base 309 for clamping the flange and aligning the flange with the corresponding end of the pipe.

[0060] Furthermore, the support base 309 is provided with at least two clamping components 500, wherein at least one clamping component 500 may be located on the top surface of the support base 309, and at least one clamping component 500 may be installed on the side periphery of the support base 309.

[0061] For example, the support base 309 can be approximately cube-shaped, wherein a clamping component 500 can be provided on the top surface of the support base 309, and the clamping component 500 is provided on at least one side of the support base 309 in the transverse x direction, so that the flange clamped on the pipe flange splicing positioning device can be assembled with different ends on the same pipe, thereby improving the adaptability of the pipe flange splicing positioning device to pipes of various sizes and angles.

[0062] In addition, this disclosure may provide a clamping component 500 on the top surface and four side peripheral surfaces of the support surface to further improve the adaptability of the pipe flange splice positioning device to pipes of various sizes and angles.

[0063] In some embodiments, there may be an intersection between the movement trajectory of the lateral component 200 and the movement trajectory of the longitudinal component 300.

[0064] For example, the transverse track 201 and the longitudinal track 301 can be arranged on the same plane and intersect, so that the transverse component 200 can move at any position on the transverse track 201 and the longitudinal component 300 can move at any position on the longitudinal track 301.

[0065] However, this disclosure also allows the longitudinal track 301 and the transverse track 201 to be spaced vertically in the z direction. For example, the longitudinal track 301 can be erected on top of the transverse track 201.

[0066] In addition, in some other embodiments, there may be no intersection between the movement trajectory of the lateral component 200 and the movement trajectory of the longitudinal component 300, which can be set according to the actual situation.

[0067] In some embodiments, the pipe flange splice positioning device may include two lateral movement assemblies 200, which are spaced apart on the base 100 along the lateral x-axis. Each of the two lateral movement assemblies 200 may be provided with a clamping assembly 500 for facing different ends of the same pipe.

[0068] For example, two transverse components 200 may be spaced apart on the transverse track 201.

[0069] When the longitudinal track 301 is mounted on the top surface of the transverse track 201, the two transverse components 200 can be located on opposite sides of the longitudinal track 301 in the transverse x direction. However, this is not a limitation; the two transverse components 200 can also be located on the same side of the longitudinal track 301 in the transverse x direction, depending on the actual situation.

[0070] In this disclosure, the clamping components 500 on the two transverse components 200 can be set relative to each other, but are not limited to this. The clamping components 500 on the two transverse components 200 can also be set in other ways besides relative setting, such as back-to-back setting. The specific setting can be made according to the actual situation.

[0071] In some embodiments, when the base 100 is provided with a plurality of driving components and two lateral moving components 200, the two driving components can be connected one-to-one with the two lateral moving components 200 to drive the corresponding lateral moving component 200 to move laterally along the x-axis. That is, the base 100 can be provided with two lateral moving driving components connected one-to-one with the two lateral moving components 200 to drive the corresponding lateral moving component 200 to move laterally along the x-axis.

[0072] However, this is not the only possibility. When the base 100 is equipped with multiple drive components and two transverse movement components 200, one drive component can simultaneously drive both transverse movement components 200 to move along the transverse x direction. For example, the transverse movement drive component in this disclosure can be a forward and reverse lead screw. In this case, the transverse movement drive component can include two first lead screws 206 with opposite thread directions and two transverse movement screw connectors 207. The two transverse movement screw connectors 207 are screwed one-to-one onto the two first lead screws 206, and the top surfaces of the two transverse movement screw connectors 207 are respectively connected to a transverse movement component 200. Under the drive of the first motor 208, the two transverse movement screw connectors 207 move towards each other or away from each other in the transverse x direction.

[0073] like Figures 8 to 10 As shown, in some embodiments, the lateral movement assembly 200 may further include a lifting track 401, which is disposed on the top surface of the lateral movement slider 202 and extends vertically in the z direction. The lifting assembly 400 is mounted on the lifting track 401 and is capable of moving vertically in the z direction relative to the lifting track 401.

[0074] Specifically, the bottom of the lifting track 401 can be connected to the top surface of the transverse base plate 203 so that it can move laterally along the x-axis under the action of the transverse slider 202 and the transverse base plate 203.

[0075] The lateral movement component 200 may include one or more lifting rails 401. The lifting rails 401 are arranged at intervals. By connecting the lifting component 400 to the multiple lifting rails 401, the connection strength between the lateral movement component 200 and the lifting component 401 can be enhanced.

[0076] The lifting assembly 400 may include a lifting slider 402, which is mounted on the lifting rail 401 and is capable of sliding along the lifting rail 401.

[0077] For example, the lifting assembly 400 may include a plurality of lifting sliders 402, which are evenly spaced along the vertical z-axis to provide uniform and stable support for the lifting assembly 400.

[0078] The lifting assembly 400 may further include a lifting base plate 403, which is located between the lifting slider 402 and the corresponding clamping assembly 500 to achieve connection and fixation between the corresponding clamping assembly 500 and the lifting slider 402. The lifting base plate 403 can drive the corresponding clamping assembly 500 to move vertically in the z direction under the action of the lifting slider 402.

[0079] The base 100 may include a third cover plate 404, which is disposed between the lifting base plate 403 and the lifting rail 401 to cover at least part of the lifting rail 401 and the lifting slider 402, thereby reducing the contact between the lifting rail 401 and the lifting slider 402 and the outside environment. The bottom of the third cover plate 404 may be connected and fixed to the transverse component 200.

[0080] A limiting groove can be provided on the side of the lifting base plate 403 that is away from the lifting rail 401. The third cover plate 404 is partially embedded in the limiting groove on the surface of the lifting base plate 403 and is spaced apart from the lifting base plate 403. This not only strengthens the limiting of the lifting base plate 403 and reduces the problem of the lifting component 400 shifting position and separating from the lifting rail 401, but also reduces the friction between the lifting component 400 and the third cover plate 404 during the lifting process.

[0081] The lifting assembly 400 may include a lifting limit member 405. The lifting limit member 405 is disposed on the side of the lifting base plate 403 opposite to the corresponding clamping assembly 500. In the direction away from the clamping assembly 500, the lifting limit member 405 protrudes from the side of the lifting track 401 opposite to the lifting base plate 403, so as to improve the problem of the lifting assembly 400 deviating from the lifting track 401.

[0082] When the base 100 includes one lifting rail 401, two lifting limit members 405 can be provided on the side of the lifting base plate 403 opposite to the corresponding clamping component 500, with the two lifting limit members 405 located on opposite sides of the lifting rail 401. When the base 100 includes multiple lifting rails 401, two lifting limit members 405 can be provided on the side of the lifting base plate 403 opposite to the corresponding clamping component 500, with the two lifting limit members 405 located on opposite sides of all lifting rails 401, that is, in the arrangement direction of all lifting rails 401, the two lifting limit members 405 are located on opposite sides of all lifting rails 401.

[0083] The driving component that drives the lifting assembly 400 to move vertically along the z-axis is defined as the lifting drive assembly. The lifting drive assembly may include a third lead screw 406, a lifting screw connector 407, and a third motor 408. The third lead screw 406 is located on the side of the lifting base plate 403 near the lifting rail 401 and extends vertically along the z-axis. When the base 100 has multiple lifting rails 401, the third lead screw 406 may be located in the middle of the multiple lifting rails 401. The lifting screw connector 407 is sleeved on the outer periphery of the third lead screw 406 and is threadedly connected to the third lead screw 406. The lifting screw connector 407 is connected to the lifting assembly 400. Specifically, the lifting screw connector 407 may be connected to the side of the lifting base plate 403 opposite to the corresponding clamping assembly 500. The third motor 408 can be located at the end of the third lead screw 406. For example, the third motor 408 can be located at the top of the third lead screw 406 to drive the third lead screw 406 to rotate and drive the lifting screw 407 to move vertically z relative to the third lead screw 406, thereby driving the lifting assembly 400 to move vertically z.

[0084] In some embodiments, the lifting assembly 400 may include a support 409 located below the corresponding clamping assembly 500. The inner end of the support 409 is connected to the lateral movement assembly 200, and the outer end of the support 409 extends in a direction away from the lateral movement assembly 200, so that its outer end protrudes outward from the corresponding clamping assembly 500. During the assembly of the pipe with the flange on the clamping assembly 500, the support 409 can support the pipe, making it easier for operators to work.

[0085] Furthermore, a support roller 410 can be provided at the outer end of the support 409. The axis of the support roller 410 is perpendicular to the vertical z direction. While supporting the pipeline, the support 409 can also drive the pipeline to move along the extension direction of the support 409.

[0086] It should be noted that during the welding process, the pipeline will expand and contract due to the heat input, resulting in a certain amount of axial expansion and contraction. By setting up the support rollers 410, the pipeline can move freely axially with thermal expansion and contraction, avoiding additional stress caused by excessive constraint, and thus preventing welding deformation such as bending and ellipticing of the pipeline. In addition, compared with directly supporting the pipeline by the support brackets 409, the present disclosure can reduce friction during pipeline movement by setting up the support rollers 410, reduce movement resistance, thereby achieving energy saving and reducing the risk of pipeline damage.

[0087] In some embodiments, the clamping assembly 500 is rotatable along its central axis.

[0088] For example, the clamping assembly 500 may include a connecting shaft 501, a rotating bearing, and a clamping structure. The inner end of the connecting shaft 501 is connected to the lifting base plate 403, and the connecting shaft 501 extends in a direction away from the lifting base plate 403. The rotating bearing is sleeved on the outer periphery of the connecting shaft 501, and the clamping structure is connected to the outer peripheral surface of the rotating shaft, so that the clamping structure can rotate circumferentially along the connecting shaft 501 under the action of the rotating shaft to achieve the positioning of the flange and the pipe on the clamping assembly 500.

[0089] Furthermore, the clamping structure may include a main body with multiple pins 502, each corresponding to a pin hole on the flange. When the flange is installed on the clamping assembly 500, the pins 502 are engaged in the corresponding pin holes of the flange to position the flange on the main body. The main body may also have at least two clamping members 503, located at either end of the connecting shaft 501. One end of each clamping member 503 is hinged to the main body via a hinge shaft, allowing the clamping member 503 to rotate around the hinge shaft to clamp or release the flange.

[0090] In some embodiments, the clamping assembly 500 is detachably connected to the corresponding lifting assembly 400 and the corresponding longitudinal movement assembly 300, thereby facilitating the replacement of the clamping assembly 500 in the pipe flange splicing positioning device.

[0091] For example, when it is necessary to connect pipes and flanges of different diameters, the clamping assembly 500 provided on the lifting assembly 400 and the longitudinal movement assembly 300 can be replaced to clamp flanges of different sizes.

[0092] It should be noted that the pipe flange assembly positioning device of this disclosure is applicable to the field of vehicle manufacturing technology, for example, it can be applied to the fabrication of tank truck unloading pipelines. However, it is not limited thereto, and the pipe flange assembly positioning device of this disclosure can also be applied to the positioning and assembly of pipes and flanges in other technical fields besides vehicle manufacturing.

[0093] The first motor 208, the second motor 308, and the third motor 408 in this disclosure can all be servo motors. By cooperating with the lead screw, the movement distance of the transverse component 200, the longitudinal component 300, and the lifting component 400 can be automated, thereby improving the movement accuracy and ensuring the assembly accuracy between the flange and the pipe on the pipe flange splicing positioning device.
