Description

Technical Field

[0001] This utility model relates to the field of welding processing tooling technology, specifically a butt joint tooling for straight seam welding of pipelines. Background Technology

[0002] In the straight seam welding of metal pipe workpieces, the seam alignment accuracy is a key factor affecting the welding quality. Traditional manual seam alignment methods are inefficient and cannot meet the needs of mass production. Moreover, the seam alignment accuracy is greatly affected by the operator's experience, which can easily lead to problems such as misalignment and uneven gaps, resulting in welding defects (such as incomplete penetration and weld beads), which does not meet the safety and efficiency requirements of modern enterprises.

[0003] Therefore, a butt joint tooling for straight seam welding of pipes is needed to improve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a butt joint tool for straight seam welding of pipelines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A butt joint tooling for straight seam welding of pipes includes a main frame, a left slide rail and a right slide rail installed on the base surface of the main frame, a clamping mechanism on the opposite outer wall of the main frame, a pipe lifting device installed on the outer wall of the main frame, a mandrel fixing component installed on the outer wall of the main frame, a clamping device installed on the outer wall of the main frame, a positioning cylinder slide on the outer wall of the main frame, a piano key drive component installed on the outer wall of the main frame, and an electrical cabinet installed on the outer wall of the main frame.

[0007] As a preferred embodiment of this utility model, the clamping mechanism includes a clamping adjustment plate, which is installed on the outer wall of the main frame. A motor mounting base is installed on the outer wall of the clamping adjustment plate. A servo motor reducer is installed on one side of the outer wall of the motor mounting base, and a coupling is installed on the other side of the outer wall of the motor mounting base. A screw jack is installed on the outer wall of the coupling.

[0008] Through the above technical solution: when the servo motor reducer in the clamping mechanism is running, the servo motor reducer drives the screw jack to run through the coupling, and at the same time the connecting rod drives the screw jacks on both sides to run, which will cause the valve base at one end of the screw jack to run.

[0009] As a preferred embodiment of this utility model, a connecting rod is installed at one end of the coupling, a valve base is installed on the outer wall of the screw jack, a valve fixator is installed on the outer wall of the valve base, and a valve component is provided on the outer wall of the valve fixator.

[0010] The above technical solution allows the valve component to fix and limit the material. The valve component is located directly above the valve base. When one end of the screw jack moves the valve base, the valve base will move longitudinally through the valve fixer. At this time, the two sides of the material are pushed by the valve component, which makes the opening of the material smaller.

[0011] As a preferred embodiment of this utility model, the left slide rail and the right slide rail are respectively located on the opposing base surfaces of the main frame, and the clamping mechanism is provided in two sets and is respectively located on the outer wall of the main frame.

[0012] As a preferred embodiment of this utility model, the welded pipe jack is located on one side of the clamp, and the screw jack is provided in two sets, which are respectively located on the outer walls opposite to the connecting rods.

[0013] As a preferred embodiment of this utility model, the valve components are provided in multiple sets and are respectively located on the outer wall of the valve fixator, and the valve components are, from left to right, valve #60, valve #65 and valve #80.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the clamping mechanism in the butt welding fixture for straight seam welding of pipelines utilizes the fact that after the workpiece enters the welding position, the clamping mechanisms on both sides move to the pre-clamping position. At this time, the material on both sides is pushed by the valve component, and the opening becomes smaller, but the seam is not yet closed. Subsequently, the positioning plate of the positioning cylinder slide is lifted, and the clamping mechanisms on both sides move to the clamping position. The key drive component moves to press the plates on both sides of the material opening onto the outer wall of the mandrel fixing component for fixation, thus completing the seam closure. This can accurately realize straight seam welding, thereby helping to solve the problems of low efficiency and difficulty in meeting the needs of mass production in the traditional manual butt welding method. Moreover, the butt welding accuracy is greatly affected by the operator's experience, and problems such as misalignment and uneven gaps are prone to occur, resulting in welding defects (such as incomplete penetration, weld beads, etc.), which do not meet the requirements of safe and efficient production in modern enterprises.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figure 1-8 This utility model provides a technical solution:

[0027] A butt joint tooling for straight seam welding of pipes includes a main frame 1, a left slide rail 2 and a right slide rail 3 installed on the base surface of the main frame 1, a clamping mechanism 4 installed on the opposite outer wall of the main frame 1, a pipe lifting device 5 installed on the outer wall of the main frame 1, a mandrel fixing component 6 installed on the outer wall of the main frame 1, a clamping device 7 installed on the outer wall of the main frame 1, a positioning cylinder slide 8 installed on the outer wall of the main frame 1, a piano key drive component 9 installed on the outer wall of the main frame 1, and an electrical cabinet 10 installed on the outer wall of the main frame 1.

[0028] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The clamping mechanism 4 includes a clamping adjustment plate 41, which is installed on the outer wall of the main frame 1. A motor mounting base 42 is installed on the outer wall of the clamping adjustment plate 41. A servo motor reducer 43 is installed on one side of the outer wall of the motor mounting base 42. A coupling 44 is installed on the other side of the outer wall of the motor mounting base 42. A screw jack 45 is installed on the outer wall of the coupling 44. A connecting rod 46 is installed at one end of the coupling 44. A valve base 47 is installed on the outer wall of the screw jack 45. A valve fixator 48 is installed on the outer wall of the valve base 47. A valve component 49 is provided on the outer wall of the valve fixator 48.

[0029] Based on the above structural features and connection relationships, the cross-section of the valve component 49 is an arc-shaped structure, so that the valve component 49 can fix and limit the material. The valve component 49 is located directly above the valve base 47. When one end of the screw jack 45 drives the valve base 47 to move, the valve base 47 will drive the valve component 49 to move longitudinally through the valve fixer 48. At this time, the two sides of the material are pushed by the valve component 49, which makes the opening of the material smaller.

[0030] Furthermore, the left slide 2 and the right slide 3 are respectively located on the opposing base surfaces of the main frame 1. The clamping mechanism 4 is provided in two sets and is located on the outer wall of the main frame 1 respectively. The welded pipe jack 5 is located on one side of the clamping device 7. The screw jack 45 is provided in two sets and is located on the opposing outer walls of the connecting rod 46 respectively. The valve components 49 are provided in multiple sets and are located on the outer walls of the valve fixator 48 respectively. The valve components 49 are arranged from left to right as 60# valve 11, 65# valve 12 and 80# valve 13.

[0031] By using the joint fixtures for straight seam welding, the precision of the joint is significantly improved, effectively ensuring welding quality, reducing welding defects, and realizing automated control of the jointing process. This eliminates the need for frequent manual adjustments, greatly reducing labor intensity and improving production efficiency.

[0032] The working process of this utility model is as follows: When using the butt joint tooling for straight seam welding of pipes designed in this scheme, after the workpiece enters the welding position, a left slide rail 2 is installed on the base surface of the main frame 1, and a right slide rail 3 is installed on the base surface of the main frame 1. Under the action of clamping mechanisms 4 set on the opposite outer walls of the main frame 1, the left slide rail 2 and the right slide rail 3 transport the workpiece. Subsequently, the clamping mechanisms 4 on both sides move to the pre-clamping position. A screw jack 45 is installed on the outer wall of the coupling 44, and a connecting rod 46 is installed at one end of the coupling 44. A valve base 47 is installed on the outer wall of the screw jack 45, and a valve retainer 48 is installed on the outer wall of the valve base 47. A valve component 49 is set on the outer wall of the valve retainer 48. When the servo motor reducer 43 in the clamping mechanism 4 operates, the servo motor reducer 43 drives the screw jack 45 to operate through the coupling 44. Simultaneously, the connecting rod 46 drives the screw jacks 45 on both sides to operate, causing the valve base 47 at one end of the screw jack 45 to operate. This causes the valve base 47 to move longitudinally through the valve retainer 48, which in turn drives the valve component 49. At this time, the two sides of the material are pushed by the valve component 49, and the opening of the material becomes smaller, but it has not yet closed. Then, the positioning plate of the positioning cylinder slide 8 is lifted, and the clamping mechanisms 4 on both sides move to the clamping position. The cylinder of the key drive component 9 is activated, pressing the plates on both sides of the material opening onto the outer wall of the mandrel retainer 6 to fix them, thus completing the closure. This can accurately realize straight seam welding, which helps to solve the problems of low efficiency of traditional manual seam alignment, difficulty in meeting the needs of mass production, and the fact that the seam alignment accuracy is greatly affected by the operator's experience, and is prone to problems such as misalignment and uneven gaps, resulting in welding defects (such as incomplete penetration, weld beads, etc.), which do not meet the requirements of modern enterprises for safe and efficient production.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
