Description

Technical Field

[0001] The present invention relates to the technical field of pipeline welding equipment, and specifically relates to a pipeline positioning welding equipment that is convenient for adapting to pipelines with different diameters. Background Art

[0002] Pipeline positioning welding equipment is mainly used for precise and efficient welding operations on pipelines. It combines automation technology and welding processes, and can achieve rapid and stable welding of pipelines. Pipeline positioning welding equipment is widely used in various pipeline projects, such as thermal pipelines, natural gas pipelines, oil pipelines, etc.

[0003] For example, the disclosed document with the publication number CN118342152A, which discloses a city pipeline welding equipment that can adapt to different pipe diameters, includes a welding frame, a centering member, a connecting plate, a welding unit, a driving device, and bolts. The centering member is located outside the welding frame. The connecting plate is slidably connected to the welding frame. The driving device is fixedly connected to the connecting plate. The welding unit is slidably connected to the connecting plate. The welding unit faces the weld of the workpiece. The centering member can be adjusted to adapt to the clamping work of pipelines with different diameters. The driving device controls the transmission speed of the connecting plate. The welding unit further includes a welding head, a clamping unit, a wire feeding unit, an intelligent control unit, a laser displacement sensor, a power supply port, a gas pipeline, and a power unit. The roughness of the weld of the workpiece is detected by the laser displacement sensor and fed back to the intelligent control unit. According to the detected roughness, the wire feeding speed of the wire feeding unit and the distance between the welding gun head and the workpiece are set, so as to ensure the smoothness and quality of welding.

[0004] Although the above equipment can perform limit welding operations on pipelines with different diameters, the stability of the above equipment for limiting and locking pipelines with different diameters only through the centering knob is insufficient, and the convenience of limiting and locking the pipelines is also insufficient, thereby reducing the stability of subsequent welding. Therefore, a pipeline positioning welding equipment that is convenient for adapting to pipelines with different diameters is needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of the present invention is to provide a pipeline positioning welding equipment that is convenient for adapting to pipelines with different diameters, so as to solve the problems mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A pipeline positioning welding equipment that is convenient for adapting to pipelines with different diameters, including a support base. A servo motor is provided at the center of the side end face of the support base, and a bidirectional lead screw is provided at the output end of the servo motor.

[0007] A positioning device. There are two groups of the positioning devices in total, and the two groups of the positioning devices are threadedly connected to the inner end face of the support base through the bidirectional lead screw.

[0008] Welding clamp seat, the welding clamp seat is fixedly arranged at the center of the upper end face of the support base, and a positioning guide groove is opened at the center of the inner end face of the welding clamp seat. A rotation module is arranged coaxially with the positioning guide groove inside the welding clamp seat, and a welding module is arranged on the inner end face of the rotation module.

[0009] Preferably, the positioning device includes a support device for support and limit. A double-shaft motor is arranged at the upper part of the inner end face of the support device. Guide gears are arranged at both output ends of the double-shaft motor. A transmission internal gear ring is rotatably clamped on the outer end face of the support device. A transmission external gear ring is arranged on the side of the transmission internal gear ring. Six groups of transmission gears are rotatably clamped equidistantly on the outer end face of the support device near the transmission internal gear ring. Six groups of alignment devices are slidably clamped equidistantly on the inner end face of the support device.

[0010] Preferably, the support device includes a motor clamp seat. Two groups of fixed guide seats are arranged at the lower end face of the motor clamp seat. The bottoms of the two groups of fixed guide seats are fixedly connected through a threaded slide seat. Six groups of alignment chutes are opened equidistantly on the outer end face of the fixed guide seat. Fixed blocks are arranged near the inner part of the inner end face of the alignment chute. A limit rotation groove is opened in the middle of the outer end face of the fixed guide seat near the alignment chute. Five groups of support rotation seats are arranged equidistantly on the outer end face of the fixed guide seat. A fixed clamping ring is arranged at the center of the outer end face of the fixed guide seat.

[0011] Preferably, the alignment device includes a pressing slide seat for support. A positioning chute is opened at the center of the inner end face of the pressing slide seat. A transmission rack is arranged at the upper part of the side end face of the pressing slide seat. A pressing block is arranged at the end of the front end face of the pressing slide seat.

[0012] Preferably, the guide gear is meshed with the transmission external gear ring, and the six groups of transmission gears are all meshed with the transmission internal gear ring. When limiting pipes with different diameters, the double-shaft motor can drive the transmission internal gear ring to rotate synchronously through the meshing of the guide gear and the transmission external gear ring, so that the transmission internal gear ring can drive the six groups of alignment devices to limit the pipes to be welded through the six groups of transmission gears, improving the adaptability of the subsequent equipment to limit different pipes.

[0013] Preferably, the fixed guide seat is threadedly slidably connected to the inner end face of the support base through the threaded slide seat to be adapted to the bidirectional lead screw. The threaded connection of the bidirectional lead screw and the two threaded slide seats can drive the two support devices to move centripetally synchronously, thereby improving the stability and accuracy of the subsequent support device to dock and limit the pipes.

[0014] Preferably, the pressing slider is slidably clamped to the inner end surface of the alignment chute by the adaptation of the positioning chute and the fixed clamping block. The fixed clamping block can cooperate with the positioning chute to provide a sufficient limiting basis for the pressing slider, thereby improving the stability of the subsequent sliding of the pressing slider inside the fixed guide.

[0015] Preferably, the transmission rack is meshed with the transmission gear, and the fixed guide and the positioning guide groove are coaxially arranged. The transmission gear can drive the six pressing clamping blocks to perform centripetal displacement through the meshing connection with the transmission rack, thereby facilitating the subsequent limiting operation on the pipe and improving the accuracy of the subsequent welding.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. By setting the positioning device, when positioning and welding pipes with different diameters, the dual-axis motor can drive the six pressing clamping blocks to perform centripetal displacement synchronously through the meshing of the guiding gear and the transmission outer gear ring, and then through the transmission inner gear ring and the six transmission gears, thereby facilitating the subsequent rapid and stable limiting of pipes with different diameters by the six pressing clamping blocks. The centripetal guiding of the six pressing clamping blocks can effectively improve the stability of the equipment for adaptively limiting pipes with different diameters, and also improve the practical performance of the equipment.

[0018] 2. During the transmission of the present invention, the dual-axis motor can drive the transmission outer gear ring to mesh and rotate with the transmission inner gear ring through the guiding gear. The transmission inner gear ring can then drive the six transmission racks to perform synchronous centripetal and centrifugal displacements through the meshing with the six transmission gears, effectively improving the stability of the equipment transmission, and also improving the utilization efficiency of the power of the equipment. At the same time, the meshing guiding method also improves the stability of the subsequent pressing clamping blocks for limiting the welded pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The positioning device 2 includes a support device 22 for support and limit. A dual-axis motor 21 is arranged at the upper part of the inner end face of the support device 22. Guide gears 27 are arranged at both output ends of the dual-axis motor 21. A transmission internal gear ring 25 is rotatably clamped to the outer end face of the support device 22, and a transmission external gear ring 24 is arranged at the side of the transmission internal gear ring 25.

A limit rotation groove 225 is opened in the middle of the outer end face of the fixed guide seat 222 near the alignment sliding grooves 224. Five groups of support rotation seats 227 are arranged equidistantly on the outer end face of the fixed guide seat 222, and a fixed clamping ring 226 is arranged at the center of the outer end face of the fixed guide seat 222.

A pressing and clamping block 261 is arranged at the end of the front end face of the pressing and sliding seat 264.

[0038] The guiding gear 27 is meshed and connected with the transmission external gear ring 24, and all six groups of transmission gears 23 are meshed and connected with the transmission internal gear ring 25.

[0042] Working principle: Before use, the staff can position the external pipeline feeding module at the front and rear of the support base 1, which is convenient for subsequent rapid feeding and discharging operations of the welded pipelines. When positioning and welding the pipelines, the external feeding module can position the pipelines at the axis of the fixed guide seat 222. At this time, the double-shaft motor 21 is started, and the double-shaft motor 21 can drive two groups of guiding gears 27 to rotate synchronously. At the same time, the two groups of guiding gears 27 can drive the transmission internal gear ring 25 to rotate through meshing with the transmission external gear ring 24. At the same time, the transmission internal gear ring 25 can drive six groups of transmission gears 23 to rotate meshingly synchronously. When the six groups of transmission gears 23 are rotating, they can drive six groups of pressing sliding seats 264 to move centripetally through meshing with six groups of transmission rack bars 262, so that the six groups of pressing sliding seats 264 can drive the pressing blocks 261 to limit the pipelines located in the middle.

The bidirectional lead screw 5 can drive two groups of pipelines to move centripetally synchronously through threaded connection with two groups of threaded sliding seats 223, so that the two groups of pipelines can be butted inside the welding clamp 8. Subsequently, the rotation module 3 can perform all-round welding operations on the butted pipelines through the welding module 4.
