[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figure 1 As shown, this utility model embodiment provides a welding production line suitable for lifting trolley components, including a front-end conveyor line 1, a three-axis positioner 2, a ceiling rail 3, and a welding station 4.

[0033] like Figure 2 ,Figure 3 As shown, the front-end conveyor line 1 is used to transport the lifting trolley components. At this time, the front-end conveyor line 1 includes a frame 11, roller chains 12, and clamping parts 13. Two roller chains 12 are arranged parallel to each other on the upper surface of the frame 11 along the transmission direction. Therefore, when the crane lifts the lifting trolley components onto the frame 11 (at this time, the lifting trolley components are simply fixed by welding between several parts), by pushing the lifting trolley components, the lifting trolley components can be matched with the clamping parts 13 below. This bottom contact rolling friction facilitates manual movement by the staff.

[0034] The roller components 121 of adjacent groups on the roller chain 12 are staggered and form an overall strip structure. This staggered distribution of the roller components 121 effectively disperses the load, enhances the stability of the overall structure, reduces local stress concentration, and lowers the risk of failure. The strip structure helps achieve a smooth motion trajectory, reduces friction and wear, and improves transmission efficiency. The staggered arrangement allows the roller components 121 to better adapt to different working environments and load changes during movement, enhancing the system's flexibility, reducing local stress concentration, and lowering the risk of failure.

[0035] The gripper 13 is located between two sets of roller chains 12. The gripper 13 has a stroke in the transmission direction and forms a vertical drive. When lifting, the upper baffle of the gripper 13 can clamp the lifting trolley component. Then it moves forward a stroke distance and then descends and returns to the initial position. The above operation is repeated. At this time, multiple sets of grippers 13 are set along the extension direction of the roller chains 12, and the stroke of adjacent sets of grippers 13 is equal. This allows the two grippers 13 to form a whole transmission of the lifting trolley component on the frame 11. Then, through the driving method of the gripper 13, the lifting trolley component is transmitted stroke by stroke until it is transmitted to the end of the frame 11, so that the gripper 31 of the overhead rail 3 can clamp and transfer it.

[0036] like Figure 4 , Figure 5 As shown, the overhead rail 3 is located at the rear end of the front conveyor line 1. The clamps 31 set on the overhead rail 3 clamp the front conveyor line 1 and transfer it to the three-axis positioner 2 for fixation.

[0037] At the same time, the gripper 31 slides laterally along the crossbeam on the upper part of the ceiling track 3, which can realize the lateral movement of the gripper 31. At this time, the gripper 31 is equipped with a vision detection component 311. Through the detection of the vision detection component 311, the gripper 31 can accurately grasp the object and improve the gripping effect.

[0038] like Figure 6As shown, the three-axis positioner 2 includes a rotating base 21 and a dual-station clamping machine 22. The rotating base 21 is located at the bottom of the dual-station clamping machine 22 and enables the overall rotation of the dual-station clamping machine 22. That is, when one set of stations in the dual-station clamping machine 22 faces the front conveyor line 1, it is used to clamp and fix the lifting trolley component. At this time, the other set of stations faces the welding station 4 at the rear end (see reference). Figure 7 This is used to weld the lifting trolley components at this workstation. During the welding process, it does not affect the operation of the preceding group of processes, thus improving the overall operation process from fixing the fixture to welding.

[0039] Each station of the dual-station clamping machine 22 is equipped with a pressing component 221 and a side pushing component 222. The pressing component 221 and the side pushing component 222 fix the lifting trolley component, thereby making the dual-station clamping machine 22. The lifting trolley component fixed on the dual-station clamping machine 22 is welded through the welding station 4.

[0040] A slide rail 223 is provided at the bottom where the pressing member 221 is located, and the pressing member 221 slides along the slide rail 223 at the bottom. This slide rail 223 can meet the clamping of different length dimensions, so the overall adaptability is higher.

[0041] Furthermore, a rotating gear 224 is provided on both sides of each station of the dual-station clamping machine 22. The lifting trolley component located at the station is flipped by rotating the gear 224. That is, when the rotating gear 224 rotates, the lifting trolley component in the clamped state can be displayed at different angles, which facilitates welding operations at welding station 4 at different angles.

[0042] The two stations of the dual-station clamping machine 22 are separated by a light shield 225, so the sparks generated during welding will not affect the safety of the operator at the outer clamping station.

[0043] This embodiment improves the overall efficiency and safety of the welding production line for lifting trolley components through reasonable structural design and efficient operation process.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
