Technical Field
[0001] This utility model relates to the field of welding technology, specifically a tooling mold for welding forklift lifting frames. Background Technology
[0002] Forklifts are industrial transport vehicles primarily used for handling palletized goods, performing loading, unloading, stacking, and short-distance transportation tasks. Equipped with wheels, they can operate flexibly in a variety of environments, including warehouses, distribution centers, and logistics hubs. Furthermore, forklifts are designed to operate inside ship holds, train carriages, and containers. Forklifts are favored for their high efficiency, ease of operation, and excellent maneuverability. During forklift manufacturing, the welding quality of the lifting frame directly affects the forklift's performance and safety.
[0003] During the welding process of the forklift lifting frame, it is necessary to first use positioning fixtures to simultaneously position each part of the forklift lifting frame and perform spot welding to complete the initial fixation. Then, reinforcement welding is carried out at the bottom position where reinforcement is needed. During the reinforcement welding process, the welding robot needs to move continuously to form welding rods. Therefore, the fixture structure needs to be able to reliably fix the structural features of the workpiece to be welded, and the fixture structure should be simple and not hinder the continuous movement of the welding robot.
[0004] Existing fixtures suffer from problems such as inaccurate positioning, unstable clamping, or complex operation, and cannot clamp the workpiece from multiple directions. These problems limit the improvement of welding efficiency and product quality. Utility Model Content
