Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Example 1

[0043] Please see Figures 1-6 The present invention provides the following technical solution:

[0044] A six-axis robot for automatically switching welding torch heads includes:

[0045] Six-axis robot body 1;

[0046] Welding gun head body 2, which is located on one side of the six-axis robot body 1;

Since the driving gear 308 and the three driven gears 309 mesh with each other, and the three transmission seats 313 are respectively fixed to one end of the three driven gears 309, the rotation of the driving gear 308 drives the three transmission seats 313. 3. The robot rotates, and three transmission seats 313 slide into the interiors of three lead screws 402 respectively. The rotation of the three transmission seats 313 drives the three lead screws 402 to rotate, thereby causing the nuts 403 threaded onto the surfaces of the three lead screws 402 to slide outward. Under the action of force, multiple connecting blocks 404 slide into the interiors of multiple connecting slots 311 respectively, completing the installation and connection between the six-axis robot body 1 and the welding gun head body 2. When the six-axis robot performs different welding tasks, it eliminates the need for manual disassembly and switching of the welding gun head, and has the function of automatically switching welding gun heads, realizing the automated switching of welding processes, improving the efficiency of the welding operation of the six-axis robot, and reducing the waste of time and human resources.It should be noted that the specific models of the six-axis robot body 1, welding gun head body 2, first motor 302, second motor 304, and telescopic rod 405 used shall be selected by those skilled in the art.

[0064] A snap-fit ​​assembly is provided within the snap-fit ​​base 401 to achieve a snap-fit ​​fixation between the six-axis robot body 1 and the welding gun head body 2.

[0065] In this embodiment: the telescopic rod 405 extends in length, thereby pushing the two locking blocks 406 through the sliding groove 409 and into the extrusion groove 410. Then, the first motor 302 drives the rotating shell 303 to rotate 90 degrees. At this time, the outer surface of the telescopic rod 405 and the two locking blocks 406 and the inner surface of the sliding groove 409 are in a cross shape. Then, the telescopic rod 405 is controlled to retract in length.

[0068] Telescopic rod 405 is fixedly connected to the inner surface of connecting seat 307, and two snap-fit ​​blocks 406 are fixedly connected to the outer surface of telescopic rod 405.

[0069] In this embodiment: the sliding groove 409 and the pressing groove 410 facilitate the sliding of the telescopic rod 405 and the two locking blocks 406. The telescopic rod 405 is controlled to extend its length, thereby pushing the two locking blocks 406 through the sliding groove 409 and into the interior of the pressing groove 410. Then, the first motor 302 drives the rotating shell 303 to rotate 90 degrees. At this time, the outer surface of the telescopic rod 405 and the two locking blocks 406 and the inner surface of the sliding groove 409 are in a cross shape. Then, the telescopic rod 405 is controlled to retract its length. Under the action of force, the two locking blocks 406 slide into the two locking grooves 411, completing the locking and fixing work between the six-axis robot body 1 and the welding gun head body 2.

Then, the telescopic rod 405 is controlled to retract, and under the action of force, the two locking blocks 406 slide into the two locking grooves 411, completing the locking and fixing work between the six-axis robot body 1 and the welding gun head body 2. Next, the second motor 304 is started to drive the drive gear 308 to rotate, and at the same time, it drives the three driven gears 309 and the three transmission seats 313 to rotate, so that the three transmission seats 313 slide into the three lead screws 402 respectively. According to the rotation of the three transmission seats 313, The motor drives three lead screws 402 to rotate, which in turn causes the nuts 403 threaded onto the surfaces of the three lead screws 402 to slide outward. Under the action of force, multiple connecting blocks 404 are pushed into the interior of multiple connecting grooves 311, strengthening the connection between the six-axis robot body 1 and the welding gun head body 2. When the six-axis robot body 1 needs to switch to the welding gun head body 2, the telescopic rod 405 is extended, causing the two locking blocks 406 to disengage from the interior of the two locking grooves 411. Then, the first motor 302 is rotated 90 degrees in the opposite direction. At this time, the outer surfaces of the telescopic rod 405 and the two locking blocks 406 match the inner surfaces of the sliding grooves 409, thereby disengaging the telescopic rod 405 and the two locking blocks 406 from the interior of the sliding grooves 409, completing the disassembly of the welding gun head body 2.
