Description

Technical Field

[0001] This utility model relates to the field of oil pipe processing technology, and in particular to a continuous welding production equipment for oil pipes with automatic deviation correction function. Background Technology

[0002] In the fields of oil, natural gas, mineral extraction and energy transportation, oil pipelines serve as the core transport carrier. Their quality and performance directly determine the safety, efficiency and economy of energy transmission. They must withstand the tests of high pressure, corrosion, temperature changes and complex geological environments for a long time. Therefore, there are strict standards for material selection, structural design and performance indicators. When processing oil pipelines, a continuous welding production equipment for oil pipelines is required. Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] To address this, patent publication CN212019905U discloses an oil pipe welding device, belonging to the field of mechanical equipment technology. It includes a fixed support, a welding assembly, and an oil pipe positioning assembly. Both the welding assembly and the oil pipe positioning assembly are fixed to the support assembly, with the welding assembly positioned above the oil pipe positioning assembly. The welding assembly includes a first reducer, a second reducer, a first gear, a second gear, a base, a drive shaft, a welding torch, a rack, and a linear guide. The first reducer controls the meshing rotation of the first and second gears, driving the drive shaft to rotate. The second reducer drives the third gear to move up and down on the rack. The oil pipe positioning assembly includes a third bearing for fixing the oil pipe, a rotating shaft, a platform, and a chuck. The oil pipe positioning assembly also includes a third reducer that drives the rotating shaft to rotate and a fourth gear. This invention significantly improves workpiece efficiency and precision, and features a simple structure, no safety hazards, and a compact design.

[0004] The aforementioned oil pipe welding device can greatly improve the efficiency and precision of the workpiece, and has the characteristics of simple structure, no safety hazards, and compactness. However, when processing the oil pipe, the oil pipe may deviate, affecting the welding effect, and the position of the oil pipe needs to be adjusted to correct the deviation. Utility Model Content

[0005] The purpose of this invention is to provide a continuous welding production equipment for oil pipes with automatic deviation correction function, so as to solve the defect of existing continuous welding production equipment for oil pipes that is difficult to correct deviation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a continuous welding production equipment for oil pipes with automatic deviation correction function, including a base;

[0007] The base has legs installed on both sides of its bottom end, and a workbench is installed on the top of the base. A bracket is installed on the top of the workbench, and a vision sensor is installed on the inner side of the bracket.

[0008] A hydraulic cylinder is installed at the top of the support, a hydraulic rod is installed at the bottom of the hydraulic cylinder, a welding head is installed at the bottom of the hydraulic rod, and a moving mechanism is installed at the top of the workbench.

[0009] The moving mechanism is disposed in a moving slot including the top of the worktable, and a moving block is installed inside the moving slot, with a threaded rod passing through the inside of the moving block.

[0010] In use, the rotating motor first drives the second gear to rotate, which in turn drives the first gear at the top to rotate. The rotation of the first and second gears drives the transmission wheel to rotate in opposite directions. The oil pipe can be moved by the rotation of the transmission wheel, allowing it to reach the bottom of the welding head. The oil pipe moves along both sides of the top of the worktable. The operation of the hydraulic cylinder drives the hydraulic rod to rise and fall, which in turn drives the welding head to rise and fall. When the welding head descends, the oil pipe can be welded.

[0011] Furthermore, a transmission mechanism is installed at the top of the workbench. The transmission mechanism includes a mounting frame installed at the top of the workbench. A transmission wheel is installed on the inner side of the mounting frame. A first gear is installed at one end of the transmission wheel, and a second gear is provided at the bottom end of the first gear. A rotary motor is installed at one end of the second gear. The transmission mechanism can drive the oil pipe to move.

[0012] Furthermore, a servo motor is installed at one end of the threaded rod, a cylinder is installed at the top of the moving block, and a telescopic push rod is installed at the top of the cylinder. The moving mechanism can correct the deviation of the oil pipe.

[0013] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the moving block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the moving block are threadedly connected, and the rotation of the threaded rod will drive the moving block to move.

[0014] Furthermore, the outer diameter of the moving block is smaller than the inner diameter of the moving groove, and the moving block and the moving groove form a sliding structure, allowing the moving block to slide within the moving groove.

[0015] Furthermore, a limiting structure is installed at the top of the moving mechanism. The limiting structure includes a second limiting plate installed at the top of the moving mechanism. A first limiting plate is provided at the top of the second limiting plate, and fixing screws pass through both ends of the first limiting plate. A rotating block is installed at the bottom end of the fixing screws. The limiting structure can limit the oil pipe.

[0016] Furthermore, the rotating block and the fixing screw form a threaded connection, and the rotating block is symmetrically distributed about the central axis of the first limiting plate. The rotation of the fixing screw can drive the first limiting plate to move.

[0017] The advantages of the continuous welding production equipment for oil pipes with automatic deviation correction function provided by this utility model are as follows: during use, the oil pipe can be moved by the transmission mechanism, the oil pipe can be limited by the limiting structure to prevent the oil pipe from deviating, and the position of the oil pipe can be adjusted by the moving mechanism to allow the oil pipe to be corrected.

[0018] By setting a movable groove at the top of the worktable, the movable block can slide inside the movable groove. The threaded rod and the movable block form a threaded connection. When the servo motor works, it drives the threaded rod to rotate. The rotation of the threaded rod drives the movable block to move. The movement of the movable block drives the oil pipe at the top limit to move, adjusting the position of the oil pipe. At the same time, the operation of the cylinder at the top drives the telescopic push rod to extend and retract. The extension and retraction of the telescopic push rod drives the oil pipe at the limit to rise and fall. By adjusting the height and position of the oil pipe, the welding process of the oil pipe can be corrected, thereby achieving the purpose of easy correction in the continuous welding production equipment for oil pipes.

[0019] A second limiting plate is installed at the top of the telescopic push rod. The second limiting plate and the first limiting plate cooperate with each other. The fixing screw is fixed to the first limiting plate. The rotating block can rotate at the bottom of the second limiting plate. The rotation of the rotating block can drive the fixing screw to rise and fall. The rise and fall of the fixing screw will drive the first limiting plate to rise and fall, adjusting the gap between the limiting plates. When the oil pipe moves to the bottom of the welding head, the oil pipe will pass through the gap between the limiting plates. In this way, the limiting plate can limit the oil pipe. When the limiting plate moves, the oil pipe will also move. This achieves the purpose of facilitating the limiting of the oil pipe in the continuous welding production equipment.

Detailed Implementation

[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 see Figures 1-5 One embodiment of this utility model is a continuous welding production equipment for oil pipes with automatic deviation correction function, including a base 2.

[0028] The base 2 has two support legs 3 installed on both sides of its bottom end, and a workbench 1 is installed on the top of the base 2. A transmission mechanism 4 is installed on the top of the workbench 1. The transmission mechanism 4 includes a mounting bracket 404 installed on the top of the workbench 1. A transmission wheel 405 is installed on the inner side of the mounting bracket 404. A first gear 401 is installed on one end of the transmission wheel 405, and a second gear 402 is provided at the bottom of the first gear 401. A rotary motor 403 is installed on one end of the second gear 402.

[0029] See attached document Figure 1-2 and attached Figure 4 As shown, the operation of the rotary motor 403 drives the second gear 402 to rotate, which in turn drives the first gear 401 at the top to rotate. The rotation of the first gear 401 and the second gear 402 drives the transmission wheel 405 to rotate in opposite directions. The oil pipe can be moved by the rotation of the transmission wheel 405, allowing it to move to the bottom of the welding head 6. The oil pipe moves to the bottom of the welding head 6 via both sides of the top of the worktable 1. The operation of the hydraulic cylinder 8 drives the hydraulic rod 7 to rise and fall, which in turn drives the welding head 6 to rise and fall. When the welding head 6 descends, the oil pipe can be welded.

[0030] A bracket 5 is installed at the top of the workbench 1, and a vision sensor 11 is installed on the inner side of the bracket 5.

[0031] A hydraulic cylinder 8 is installed at the top of the support 5, a hydraulic rod 7 is installed at the bottom of the hydraulic cylinder 8, and a welding head 6 is installed at the bottom of the hydraulic rod 7. A moving mechanism 10 is installed at the top of the worktable 1, and a limiting structure 9 is installed at the top of the moving mechanism 10. The limiting structure 9 includes a second limiting plate 902 installed at the top of the moving mechanism 10. A first limiting plate 901 is provided at the top of the second limiting plate 902, and fixing screws 904 pass through both ends of the first limiting plate 901. A rotating block 903 is installed at the bottom of the fixing screw 904. The rotating block 903 and the fixing screw 904 form a threaded connection. The rotating block 903 is symmetrically distributed about the central axis of the first limiting plate 901.

[0032] See attached document Figure 1-2 and attached Figure 5 As shown, the second limiting plate 902 and the first limiting plate 901 cooperate with each other. The fixing screw 904 is fixed on the first limiting plate 901. The rotating block 903 can rotate at the bottom of the second limiting plate 902. The rotation of the rotating block 903 can drive the fixing screw 904 to rise and fall. The rise and fall of the fixing screw 904 will drive the first limiting plate 901 to rise and fall, adjusting the gap between the limiting plates. When the oil pipe moves to the bottom of the welding head 6, the oil pipe will pass through the gap between the limiting plates. In this way, the limiting plate can limit the oil pipe. When the limiting plate moves, the oil pipe will also move.

[0033] The moving mechanism 10 is disposed in the moving groove 1002 including the top of the worktable 1. The moving block 1004 is installed inside the moving groove 1002. The outer diameter of the moving block 1004 is smaller than the inner diameter of the moving groove 1002. The moving block 1004 and the moving groove 1002 constitute a sliding structure.

[0034] The movable block 1004 has a threaded rod 1003 running through its interior. The outer side wall of the threaded rod 1003 is uniformly provided with external threads, and the inner side wall of the movable block 1004 is uniformly provided with internal threads that cooperate with the external threads. The threaded rod 1003 and the movable block 1004 are connected by threads.

[0035] A servo motor 1001 is installed at one end of the threaded rod 1003, a cylinder 1005 is installed at the top of the moving block 1004, and a telescopic push rod 1006 is installed at the top of the cylinder 1005.

[0036] See attached document Figure 1-3As shown, the movable block 1004 can slide inside the movable groove 1002. The threaded rod 1003 and the movable block 1004 form a threaded connection. When the servo motor 1001 works, it drives the threaded rod 1003 to rotate. The rotation of the threaded rod 1003 drives the movable block 1004 to move. The movement of the movable block 1004 drives the oil pipe at the top limit to move, adjusting the position of the oil pipe. At the same time, the cylinder 1005 at the top works, which drives the telescopic push rod 1006 to extend and retract. The extension and retraction of the telescopic push rod 1006 drives the oil pipe at the limit to rise and fall. By adjusting the height and position of the oil pipe, the welding process of the oil pipe can be corrected. The vision sensor 11 captures the deviation data of the oil pipe weld trajectory in real time, drives the multi-axis servo system to dynamically adjust the alignment angle and position of the oil pipe, and synchronously adjusts the welding current, speed and other parameters to keep the weld in a precise docking state, forming a continuous and stable high-quality welding effect.
