Description

Technical Field

[0001] The utility model relates to the technical field of chain welding, in particular to a welding chain link welding positioning tool. Background Art

[0002] During the manufacturing process of welded chain links, traditional positioning methods often rely on manual adjustment and fixing of the chain plates. This method is not only inefficient but also makes it difficult to ensure precise positioning of the chain plates before welding. Due to the diverse specifications of chain plates, traditional positioning tooling often lacks flexibility and adaptability, and cannot meet the positioning requirements of different chain plate specifications. In addition, traditional tooling is prone to problems such as unstable positioning and insufficient clamping force during use, resulting in inconsistent weld quality, increasing production costs and quality risks.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example:

[0018] like Figure 1-2As shown, the embodiment of the present invention provides a welding chain link welding positioning tool, including a base 1, a first motor 3, a positioning shaft 11 and a second motor 12. A limiting slot 2 is provided on the top of the base 1, the first motor 3 is fixedly connected to the side wall of the base 1, the driving end of the first motor 3 is fixedly connected to a bidirectional screw rod 4, the outer surface of the bidirectional screw rod 4 has bidirectional threads threadedly connected to a movable plate 5, and the two opposite side walls of the two movable plates 5 are provided with a fixing slot 6, the second motor 12 is fixedly connected to the front surface of the movable plate 5, the driving end of the second motor 12 is fixedly connected to a bidirectional threaded rod 8, the bidirectional threaded rod 8 is located inside the fixing slot 6, the end of the bidirectional threaded rod 8 away from the second motor 12 is rotatably connected to the inner wall of the fixing slot 6, the outer surface of the bidirectional threaded rod 8 has bidirectional threads threadedly connected to a positioning plate 7, the two positioning plates 7 are symmetrically slidably clamped in the inside of the fixing slot 6, the opposite side walls of the two movable plates 5 are provided with a T-slot 9, the inner sliding clamp of the T-slot 9 is clamped with a limiting block 10, and the positioning shaft 11 is fixedly connected to the side wall of the limiting block 10.

[0019] The two movable plates 5 are symmetrically slidably engaged in the inner portion of the limiting groove 2. This design ensures the stability and accuracy of the movable plates 5 during movement. Guided by the limiting groove 2, the movable plates 5 can slide smoothly along the predetermined trajectory, thereby achieving precise positioning and clamping of the chain plate.

[0020] Positioning shaft 11 is located diagonally above positioning plate 7, with its center axis lying on the plane of symmetry between the two positioning plates 7. This layout not only allows positioning shaft 11 to accurately pass through the pin holes in the chain plates, but also ensures the stability and balance of the chain plates during positioning. Furthermore, this design of positioning shaft 11 facilitates quick and accurate positioning and adjustment of the chain plates by the operator.

[0021] The inner top wall of the T-slot 9 and the top of the movable plate 5 are in the same plane. This design allows the positioning shaft 11 to be inserted into the T-slot 9 from the top of the movable plate 5 via the stopper 10, so that the stopper 10 on the positioning shaft 11 can be smoothly engaged with the movable plate 5. This tight fit not only enhances the overall stability of the tooling, but also allows the positioning shaft 11 to be easily replaced and adjusted to accommodate chain plates of different specifications.

[0022] One end of the positioning shaft 11 close to the limit block 10 contacts the side wall of the movable plate 5. This design ensures the position of the chain plate on the positioning shaft 11, so that the chain plate on the positioning shaft 11 can be close to the side wall of the movable plate 5 to ensure the precise alignment of the chain plate before welding.

[0023] Working Principle: When using the welding and positioning fixture for chain links, the operator first secures the two chain plates to be welded to the positioning shafts 11. During this step, the positioning shafts 11 pass through the pin holes in the chain plates, providing initial positioning and support. Next, driven by the second motor 12, the bidirectional threaded rod 8 begins to rotate. This simultaneously drives the two positioning plates 7 on either side of the chain plate along the fixing slots 6 toward the chain plate on the positioning shafts 11. As the positioning plates 7 move, they gradually clamp the two sides of the chain plate, thereby precisely positioning the chain plates. After the chain plates are positioned, the operator attaches a pin sleeve to one of the positioning shafts 11. This step connects the two chain plates via the pin sleeve, preparing for subsequent welding. Next, driven by the first motor 3, the bidirectional lead screw 4 begins to rotate. This drives the two movable plates 5 toward each other. As the movable plate 5 moves, the other end of the pin sleeve secures itself to the other positioning shaft 11. The positioning of the chain links is not truly completed until the chain plates on the two positioning shafts 11 are pressed against the two ends of the pin sleeves. The design of this tooling also fully takes into account the needs of welding chain links of different specifications and sizes. The positioning shaft 11 is clamped in the T-slot 9 on the movable plate 5 through the limit block 10. This design allows positioning shafts 11 of different specifications and sizes to be suitable for pin holes of different specifications and sizes on the chain plate. Therefore, the operator can replace positioning shafts 11 of different specifications and sizes according to the specifications and sizes of the chain links to be welded. In addition, the spacing between the two positioning plates 7 is also adjustable. This means that the two positioning plates 7 can clamp chain plates of different specifications and sizes, thereby ensuring the stability of the chain plates and the accuracy of positioning. Similarly, the spacing between the two movable plates 5 is also adjustable, which allows the spacing between the chain plates on the two positioning shafts 11 to be changed, thereby adapting to the pin sleeves between the two chain plates of different specifications and sizes.

[0024] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
