[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1-Figure 8As shown, a welding platform of a welding robot includes a welding table 1 for fixing and supporting and a locking fixture 4 for clamping parts, and also includes a fixing mechanism 2 for releasing stress of parts after welding and a locking mechanism 3 for limiting the position of the fixing mechanism 2. A plurality of groups of fixing mechanisms 2 are installed on the welding table 1. The fixing mechanism 2 is installed on the welding table 1 through the locking mechanism 3, and the locking fixture 4 is installed on the fixing mechanism 2.

[0031] like Figure 2 As shown, the fixing mechanism 2 includes a sliding lock platform 21, a sliding groove 22 for limiting the sliding of the sliding lock platform 21 is formed on the welding platform 1, a bottom support seat 23 is installed on the inner side of the welding platform 1 and located below the sliding lock platform 21, and a limiting slider 24 is installed on the bottom support seat 23 corresponding to the bottom of the sliding lock platform 21;

[0032] The locking mechanism 3 includes a locking screw 32, which passes through the sliding locking platform 21. A matching groove 34 for matching the locking screw 32 is formed on the sliding locking platform 21. A locking assembly is installed inside the sliding locking platform 21. The locking screw 32 limits the position of the sliding locking platform 21 through the locking assembly. One end of the locking screw 32 passes through the welding platform 1 and is installed with a tightening handwheel 31. A locking nut 33 is welded on the tightening handwheel 31.

[0033] In this embodiment, if Figure 5-7 As shown, the locking assembly inside the sliding lock platform 21 includes a matching block 36, the matching block 36 is fixedly connected to the sliding lock platform 21, a locking block 35 is arranged on one side of the matching block 36, the matching end faces of the matching block 36 and the locking block 35 are both inclined surfaces, and a buffer assembly for resisting the instantaneous effect of stress is arranged inside the locking block 35.

[0034] In this embodiment, if Figure 8 As shown, the buffer assembly inside the locking block 35 includes an extrusion ring 351, an extrusion groove 352 is formed inside the locking block 35, the locking screw 32 passes through the extrusion ring 351 and the sliding lock platform 21, the extrusion ring 351 is threadedly matched with the locking screw 32, the extrusion ring 351 is connected to the locking block 35 along the axial sliding of the locking screw 32, and the outer cylindrical surface of the extrusion ring 351 is splined to match the locking block 35, and a spring 353 is installed on the side of the extrusion ring 351 corresponding to the matching block 36.

[0035] In this embodiment, supporting legs are fixed to the bottom of the welding platform 1 .

[0036] In this embodiment, the locking fixture 4 connects the sliding locking platform 21 and the welding platform 1 by means of bolts.

[0037] In this embodiment, a discharge port is formed on the bottom support seat 23 at a position corresponding to the sliding lock platform 21 .

[0038] In this embodiment, a sliding groove that matches the locking screw 32 is formed on the matching block 36 , and a through groove that matches the locking screw 32 is formed on the locking block 35 .

[0039] Working principle: first adjust the positions of multiple locking fixtures 4 according to the workpiece to be processed, and at the same time, twist the locking screw 32 in the positive direction, so that the locking screw 32 can fit the extrusion ring 351 through the thread, so that the extrusion ring 351 first squeezes the spring 353, and then squeezes the spring 353 to squeeze the locking block 35 to squeeze the matching block 36, so that the sliding lock platform 21 is driven to move horizontally to the rear side position on the sliding groove 22, until the sliding lock platform 21 is pressed against the side wall of the sliding groove 22. After multiple sliding lock platforms 21 are fixed, the workpiece is completely fixed;

[0040] After welding with the welding robot, there is internal stress on the workpiece, and the stress needs to be released slowly. At this time, the locking screw 32 is turned in the opposite direction to make the locking screw 32 drive multiple extrusion rings 351 to cooperate. At this time, the spring 353 is gradually released, and at the same time, the pressure between the inclined surfaces of the locking block 35 and the matching block 36 is gradually reduced. The friction force of the inclined surface and the internal potential energy of the spring 353 are used to slowly release the stress of the workpiece to avoid popping out. At the same time, there is no need to move and adjust the locking clamp 4 to ensure the accuracy of the subsequent positioning of the locking clamp 4. The locking screw 32 is continuously twisted until the stress of the workpiece is completely released, and the locking clamp 4 is released to remove the workpiece.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
