[0002] Alloy steel possesses excellent properties such as high strength and high toughness, and is widely used in industrial production. However, welding alloy steel presents numerous challenges, such as easy oxidation and deformation of the welded area, and difficulty in guaranteeing weld quality. Traditional methods for welding alloy steel primarily rely on manual operation or simple mechanical aids. However, these methods have several shortcomings: firstly, manual operation has low precision, easily leading to unstable weld quality; secondly, the operation process is complex, time-consuming, and inefficient; furthermore, due to the lack of effective auxiliary devices, welding defects such as porosity and cracks are prone to occur during the welding process, severely affecting the strength and reliability of the welded joint. Utility Model Content

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0027] To understand this application, it is necessary to understand its application scenario. In the welding process of many alloy steels, two components are often connected, so it is necessary to fix and fit component A and component B separately at the same time.

[0028] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: an alloy steel welding auxiliary device, characterized as follows:

[0029] The fixed base 1 is the basic component of this device, and its side is provided with a groove 2. The fixed base 1 is made of high-strength alloy steel to ensure sufficient stability and high-temperature resistance during welding. The depth and width of the groove 2 are adapted to the size of the hinge block 3 to ensure that the hinge block 3 can rotate flexibly. The hinge block 3 is connected to the hinge point in the groove 2 through the hinge shaft, so that the hinge block 3 can rotate within the groove 2. The material of the hinge block 3 is selected as alloy steel with good wear resistance to ensure its reliability in long-term use. The positioning block 4 is connected to the hinge block 3 through a connector. The side wall of the positioning block 4 is designed with an inclined surface 5, which is provided with a through groove 6. Several through holes 7 are evenly distributed on the inclined surface 5. These through holes 7 lead to the through groove 6 to facilitate the positioning and fixing of the alloy steel needle-like parts on the workpiece. When the hinge block 3 rotates, the positioning block 4 rotates accordingly. The angle design of the inclined surface 5 allows the workpiece to automatically slide into the through groove 6 when placed and be fixed through the through holes 7, thereby achieving precise positioning of part A of the workpiece. The U-shaped base 8 is mounted on the fixed base 1. The top of each side wall of the U-shaped base 8 is designed as two mutually perpendicular inclined surfaces 9. A stop block 10 is located on the inclined surface 9 closest to the inclined surface 5. The side wall of the stop block 10 has a groove 11, the plane of which is perpendicular to the inclined surface 5. This design allows part B of the workpiece to slide in through the groove 11 during placement and precisely mate with part A, ensuring accurate welding position. The top of the J-shaped block 12 is connected to the inside of the U-shaped base 8 via a hinge shaft, and its bottom is equipped with a positioning pin 13. A limiting post 14 is located on the side wall of the U-shaped base 8, between the hinge shaft of the J-shaped block 12 and the positioning block 4. The two ends of the spring 15 are connected to the positioning pin 13 and the limiting post 14, respectively. When the workpiece is placed in the device and welding is performed, the J-shaped block 12 provides uniform elastic support to part B of the workpiece through the spring 15, optimizing the force distribution on the workpiece and ensuring welding quality.

[0030] It should be noted that the limiting block 16 is a rectangular block structure, which is respectively set on both sides of the hinge block 3. The end of the limiting block 16 extends out of the groove 2 to limit the rotation angle of the hinge block 3 in the groove 2, so as to prevent the hinge block 3 from rotating excessively and causing the positioning block 4 to have an error in the fit with the workpiece to be welded.

[0031] Furthermore, a protrusion 17 is provided on the side wall of the hinge block 3. The specific position and shape of the protrusion 17 are designed as follows: the protrusion 17 is located slightly below the middle of the side wall of the hinge block 3, and is a right-angled triangle with a sloping bottom and a flat top. The main function of the protrusion 17 is to provide a point of force for rotating the hinge block 3, allowing the user to press the protrusion 17 with their fingers or other tools to achieve the rotation of the hinge block 3.

[0032] It should be noted that the J-shaped block 12 has an overall J-shaped structure, with its top end hinged to the U-shaped seat 8 via a hinge shaft, allowing it to rotate flexibly within the U-shaped seat 8 around this hinge shaft. The curved end of the J-shaped block 12, i.e., its bottom, is specially designed with a flat surface. The size and shape of this flat surface match the bottom of the alloy steel workpiece to be welded, ensuring that during the welding process, the J-shaped block 12 can closely fit the bottom of the alloy steel workpiece, providing stable and uniform support for the workpiece.

[0033] Furthermore, the thickness of the J-block 12 is precisely calculated and designed to match the spacing between the inner walls of the U-shaped seat 8. This fit ensures that the J-block 12 can rotate smoothly within the U-shaped seat 8 without excessive wobbling or instability caused by excessive gaps. Specifically, the thickness of the J-block 12 is slightly smaller than the spacing between the inner walls of the U-shaped seat 8, typically leaving a gap of 0.5mm to 1mm. This gap ensures the free rotation of the J-block 12 while effectively reducing vibration and noise caused by excessive gaps.

[0034] It should be noted that the inclined angle of the locating block 4's inclined surface 5 is precisely set to 45 degrees. This design allows the locating block 4 to provide a stable support surface when in contact with the alloy steel workpiece to be welded, while also facilitating the placement and adjustment of the workpiece. The 45-degree inclined surface 5 provides a stable support surface for the alloy steel workpiece to be welded, ensuring that the workpiece will not shift or tilt during the welding process, thereby improving the accuracy of welding positioning.

[0035] It is worth noting that the side wall of the U-shaped seat 8 is provided with multiple adjusting holes 18, which are linearly arranged and equally spaced. The limiting post 14 can be installed in any of these adjusting holes 18 via a threaded connection or other fixing method. By selecting different positions of the adjusting holes 18 to install the limiting post 14, the distance between the limiting post 14 and the locating pin 13 can be changed, thereby adjusting the tension of the spring 15. This is particularly important for alloy steel workpieces of different weights and sizes, ensuring appropriate elastic support during welding.

[0036] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
