Description

Technical Field

[0002] In the field of mechanical equipment manufacturing, welding is a key process for connecting parts, and its precision directly determines the assembly performance and service life of the equipment. Among them, earring-type parts, as common transmission and connection components, are widely used in various mechanical structures.

[0003] Traditional general-purpose tooling is suitable for welding earrings with simple, non-eccentric structures. However, it cannot be aligned when tightening complex eccentric welding earrings, resulting in skewed force and a large deviation in the perpendicularity between the earring shaft hole and the rod after tightening spot welding. This leads to rework, wasted time and effort, and affects processing efficiency and quality.

[0004] However, as mechanical products become more complex and precise, the application of eccentric earrings is increasing. Due to their eccentric structure, these earrings require extremely high symmetry in positioning and clamping during the welding process. Therefore, developing a welding positioning fixture that can adapt to eccentric structures, ensure welding positioning accuracy, and is easy to operate has become a key requirement for solving the current welding challenges of eccentric earrings and improving processing quality and efficiency.

[0020] like Figures 1 to 4 The eccentric small part welding positioning fixture shown includes a base 1, one side of which is connected to a welding platform. The other side of the base 1 is provided with a positioning plate 4 for placing an eccentric earring. The positioning plate 4 is provided with a positioning block 2 for pressing the eccentric earring. The positioning block 2 is connected to the positioning plate 4 by a locking screw 3. This eccentric small part welding positioning fixture includes a base, a positioning block, a locking screw, and a positioning plate. The base is used to install onto the welding platform, providing a fixed foundation for the entire fixture. The positioning plate is used to place the eccentric earring, and the positioning block is used to conform to the side of the eccentric earring. The locking screw can be rotated and tightened to push the positioning block to press the eccentric earring, thus fixing and locking the eccentric earring. The clamping force of the positioning block on the eccentric earring is precisely controlled by rotating the locking screw, preventing deformation of the eccentric earring due to excessive force. Simultaneously, the shape of the positioning block matches the side profile of the eccentric earring, ensuring a tight fit and no localized stress concentration when the positioning block presses the eccentric earring. The eccentric small part welding positioning fixture of this utility model realizes the precise positioning and stable clamping of eccentric earrings, ensuring the welding shape and position accuracy, while improving the versatility and ease of operation of the fixture, and reducing the rework rate and processing cost.

[0021] like Figures 1 to 4 The diagram illustrates an eccentric small part welding positioning fixture, wherein the base 1 is detachably connected to the welding platform. This utility model's eccentric small part welding positioning fixture features a detachable connection between the base and the welding platform, allowing for quick replacement of the entire fixture by disassembling the base, thus adapting to different types of eccentric small part welding needs.

[0022] like Figures 1 to 4The diagram illustrates an eccentric small part welding positioning fixture. The positioning plate 4 is detachably connected to the base 1, and the mounting position of the positioning plate 4 on the base 1 is adjustable. The positioning plate 4 and the base 1 are connected by bolts. This utility model's eccentric small part welding positioning fixture allows for adjustment of the mounting position of the positioning plate on the base, enabling adaptation to eccentric earrings with different structural parameters by changing the position of the positioning plate.

[0023] like Figures 1 to 4 The illustration shows a welding positioning fixture for eccentric small parts. The positioning plate 4 includes a side plate I 4-1, a base plate 4-2, and a side plate II 4-3. The side plates I 4-1 and II 4-3 are disposed on both sides of the base plate 4-2, and the locking screw 3 is disposed on the side plate II 4-3. The side plates I 4-1 and the base plate 4-2 are used to position the eccentric earring, and the side plates I 4-1 and the base plate 4-2 are equidistant from the center of the weld stop of the earring. The positioning plate of this invention includes a side plate I, a base plate, and a side plate II. The side plates I and the base plate are used to place the eccentric earring for initial positioning, and it is required that the distance between the upper side plate I and the base plate and the center of the weld stop of the eccentric earring be consistent to ensure accurate initial positioning of the eccentric earring after placement and to avoid welding accuracy problems caused by initial position deviation.

[0024] The eccentric small part welding positioning fixture of this utility model is used by first installing and fixing the base to the welding platform; then placing the eccentric earring to be welded in the positioning plate, and using the matching relationship between the upper side plate I, the bottom plate and the center of the earring welding stop on the positioning plate to complete the initial positioning of the eccentric earring; finally, rotating and tightening the locking screw, pushing the positioning block to press against the side of the eccentric earring, realizing the stable fixing of the eccentric earring, and then the subsequent welding operation can be carried out.

[0025] The eccentric small part welding positioning fixture of this utility model has the following advantages: Simple structure and highly versatile: It can adapt to different eccentric earring structures by changing the position of the positioning plate, making it simple in structure and highly versatile.

[0026] Replaceability and convenience: The locking screws ensure high efficiency in cyclical operations; the base is easy to disassemble and replace, greatly improving processing efficiency.

[0028] This utility model presents a welding positioning fixture for eccentric small parts, providing a welding positioning and clamping fixture that ensures accurate positioning of eccentric earrings during welding, eliminates eccentric force and deformation after clamping, and guarantees welding shape and position accuracy. It solves problems such as the inability to clamp eccentric parts, eccentric force causing welding position deviations after clamping, and the need for multiple rework, thereby improving processing efficiency and accuracy.
