[0023] An embodiment of the utility model provides a welding mechanism, including a first track 1, a welding jig 2, a clamping and shifting mechanism 3 and a welding robot 4. The first track 1, the welding jig 2 and the clamping and shifting mechanism 3 are arranged in parallel, the welding jig 2 is used to carry a first workpiece to be welded 6, the clamping and shifting mechanism 3 is used to detachably connect a second workpiece to be welded 7, and the welding robot 4 is slidably installed on the first track 1. The welding robot 4 is used to slide along the first track 1 and rotate toward the welding jig 2 to weld the first workpiece to be welded 6 or rotate toward the clamping and shifting mechanism 3 to weld the second workpiece to be welded 7.

[0024] It should be noted that, in the present embodiment, the first track 1, the welding jig 2 and the clamping and shifting mechanism 3 are arranged in parallel at intervals along the X-axis direction, and the first track 1 is extended along the Y-axis direction, that is, the length direction of the first track 1 is the Y-axis direction, and the welding robot 4 can reciprocate along the Y-axis direction through the first track 1, and the welding robot 4 can rotate forward or reverse toward the X-axis, so as to weld the first workpiece to be welded 6 on the welding jig 2 or weld the second workpiece to be welded 7 on the clamping and shifting mechanism 3.

[0025] In this embodiment, if Figure 1As shown, a first track 1, a welding jig 2, a clamping and shifting mechanism 3 and a welding robot 4 are provided to form a welding mechanism, wherein the first track 1, the welding jig 2 and the clamping and shifting mechanism 3 are arranged in parallel, that is, the welding jig 2 and the clamping and shifting mechanism 3 are distributed on both sides of the first track 1 in a direction perpendicular to its extension direction, and the welding robot 4 is slidably installed on the first track 1 and can reciprocate along the first track 1, and at the same time, the welding jig 2 can carry a first workpiece 6 to be welded, and the clamping and shifting mechanism 3 is detachably connected with a second workpiece 7 to be welded. In this way, when the welding robot 4 reciprocates along the first track 1, the first workpiece to be welded 6 and the second workpiece to be welded 7 are respectively placed on both sides of the welding robot 4 in a direction perpendicular to its moving direction by means of load-bearing and detachable connection, which is convenient for loading and unloading the first workpiece to be welded 6 and the second workpiece to be welded 7, and the welding robot 4 can rotate toward the welding jig 2 or the clamping displacement mechanism 3. In this way, the welding robot 4 can realize welding of the first workpiece to be welded 6 or the second workpiece to be welded 7 by moving along the first track 1 and rotating toward both sides of the first track 1, and realize welding of different workpieces to be welded by the same welding mechanism, which effectively expands the application range of the entire welding production line; at the same time, since the first workpiece to be welded 6 and the second workpiece to be welded The workpiece 7 can be placed on both sides of the first track 1. Therefore, when the welding robot 4 rotates to weld one of the first workpiece 6 and the second workpiece 7 to be welded, the other workpiece to be welded can be loaded without the need for the welding robot 4 to stop and wait for the loading to be completed. Correspondingly, after the welding of one type of workpiece to be welded is completed, the welding robot 4 can immediately rotate to weld the other type of workpiece to be welded that has been loaded. At this time, the welded workpiece to be welded can be unloaded without the need for the welding robot 4 to stop and wait for the unloading to be completed. Therefore, the welding operation and the loading operation or the unloading operation can be carried out simultaneously, which can effectively shorten the operation time of an automated welding operation process, and thus greatly improve the overall efficiency of the automated welding operation.

[0026] It should be noted that, in this embodiment, for example, Figure 1 As shown, the first workpiece to be welded 6 is a workpiece with a larger volume, while the second workpiece to be welded 7 is a workpiece with a smaller volume, so the length of the welding jig 2 is set to be close to the length of the first track 1, so as to stably carry the first workpiece to be welded 6, and the clamping displacement mechanism 3 can achieve a detachable connection with the second workpiece to be welded 7 through a clamp or a snap-fit ​​member, which is convenient for loading and unloading the second workpiece to be welded 7.

The clamping and shifting mechanism 3 includes a shifting machine base 31. The shifting machine base 31 has two and is arranged at intervals along the second track 5. At least one of the shifting machine bases 31 is slidably connected to the second track 5. In this arrangement, the two shifting machine bases 31 can be moved closer or farther away by moving at least one shifting machine base 31 along the second track 5, so that the two shifting machine bases 31 can be adjusted. The distance between the two positioner bases 31 allows the second workpiece 7 to be welded of different lengths to be accommodated between the two positioner bases 31, thereby increasing the types of workpieces to be welded that can be welded by the welding robot 4 and further expanding the application scope of the entire welding production line. The positioner base 31 can be detachably connected to the end of the second workpiece 7 to be welded, and the stability of the second workpiece 7 to be welded can be achieved through the coordinated clamping connection of the two positioner bases 31 to the second workpiece 7 to be welded after loading. At the same time, the convenience of loading and unloading the second workpiece 7 to be welded is improved through the detachable connection.

The placement table 34 is used to be detachably connected to the end of the second workpiece 7 to be welded.

[0033] It should be noted that, in this embodiment, Figure 1 As shown, the extension direction of the second track 5 is the Y-axis direction.

In this way, the second workpiece 7 to be welded can be clamped and connected through the placement tables 34 on the two shifting machine bases 31, thereby realizing the second workpiece 7 to be welded. The stability of the workpiece 7 after loading can be improved. At the same time, the first rotating drive member 33 can drive the rotation of the slewing support 32 to drive the placement table 34 to rotate, and then drive the second workpiece 7 to be welded after loading to rotate around the extension direction of the second track 5, that is, the second workpiece 7 to be welded can rotate so that the welding robot 4 can weld different outer surfaces of the second workpiece 7 to be welded, without the need for unloading adjustment, which effectively improves the convenience of welding operation. For example, the second workpiece 7 to be welded is a rectangular structure, and the two ends of the rectangular structure along the length direction are respectively detachably connected to the two placement tables 34. Through the rotation of the slewing support 32, the welding of the four side walls of the rectangular structure around the length direction can be realized.
