Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, and more specifically, to a welding tooling for a high-precision mounting bracket. Background Art

[0002] In traditional welding processes, to ensure that multiple parts can be accurately joined together, it is usually necessary to use a ruler or other auxiliary tools to determine the exact welding position. This process is not only time-consuming and laborious, but also requires a high level of skill from the operator, and it is prone to positioning errors, thus affecting the welding quality and efficiency. In modern industrial manufacturing, with the development of technology and the increasing requirements for production efficiency, the traditional manual positioning welding method has become difficult to meet the production needs. Therefore, a more efficient, precise and labor-cost-reducing welding positioning technology is needed to adapt to the development of modern manufacturing. In recent years, with the rapid development of automation technology and information technology, some advanced welding technologies such as laser welding and robotic welding have begun to be widely used in manufacturing. These technologies achieve the automation and precise control of the welding process through the use of computer control systems and high-precision sensors, greatly improving the welding efficiency and quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0026] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0027] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] As described in the background art, in modern industrial manufacturing, with the development of technology and the increasing requirements for production efficiency, the traditional manual positioning and welding method has been difficult to meet the production needs. Therefore, a more efficient, accurate and labor-cost-reducing welding positioning technology is needed to adapt to the development of modern manufacturing. In recent years, with the rapid development of automation technology and information technology, some advanced welding technologies such as laser welding and robot welding have begun to be widely used in the manufacturing industry. These technologies achieve the automation and precise control of the welding process by using computer control systems and high-precision sensors, greatly improving the welding efficiency and quality. However, although these technologies have achieved remarkable results in improving welding efficiency, when facing the welding of complex curved parts, how to quickly and accurately determine the welding position is still a challenge. The traditional auxiliary tools and manual marking methods are unable to handle such problems effectively and cannot meet the dual requirements of high efficiency and high precision.

[0030] To address the above problems, a welding fixture for a high-precision mounting bracket proposed in this application can accurately fix parts at a preset position before welding. This precise positioning is beneficial to ensuring the accurate relative position of parts during the welding process, thereby improving the welding precision and quality. The setting of the arc plate enables the fixture to adapt to parts with arc surfaces, increasing the applicable range of the fixture. For parts with complex shapes, the traditional planar positioning method may not meet the requirements, while the design of this fixture can better adapt to the welding of these parts. By fixing the parts on the welding rack and quickly positioning through the preset mounting holes, it reduces the dependence on the skills of operators in traditional welding and reduces the possibility of human errors. Since the parts can be quickly positioned and fixed on the welding rack, compared with manual positioning, this fixture can significantly improve the efficiency of welding operations, shorten the production cycle, reduce manual intervention, and improving welding efficiency helps to reduce the overall production cost. At the same time, improving welding precision can also reduce the defective product rate, further reducing material waste and rework costs. Using a high-precision welding fixture can ensure the repeatability and consistency of each welding, thereby improving the reliability and durability of the product. The operator only needs to place the parts on the welding rack and fix them through the mounting holes, simplifying the operation process, reducing the requirements for the skills of operators, and making the welding operation more standardized and simplified. The fixture design allows welding of parts of different sizes and shapes, improving the flexibility and versatility of the equipment.
