The top inner wall and bottom inner wall of the positioning groove 502 have two positioning holes 501. The left side of the positioning hole 501 is open, and the two positioning holes 501 that are opposite each other are aligned and connected. There are four guide pins 9, all of which are fixedly connected to the left side of the welding machine fixture base 10. The chuck base 5 is slidably sleeved on the four guide pins 9. The right side of the chuck base 5 is provided with four guide holes 503. The guide holes 503 are intersecting and communicating with the positioning grooves 502. The inner wall of the guide hole 503 is in active contact with the outer side of the corresponding guide pin 9. The left stop block 3 and the right stop block 4 of the chuck are both threadedly fixed in the positioning groove 502. The front side of the right stop block 4 of the chuck has a notch 401 with openings on the right side and bottom. The right side of both the left stop block 3 and the right stop block 4 of the chuck has a first screw hole. The right side of the chuck base 5 has two T-shaped screw holes. The same cup head screw 7 is threaded into the T-shaped screw holes and the corresponding first screw holes.

[0016] Working principle: The welding machine platform 200 can be installed on an external X and Y axis CNC module for X and Y axis movement. The welding machine platform 200 is equipped with a laser welding head, which can move up and down along the Z axis. The servo-electric rotary chuck 100 can rotate 360°, enabling 4-axis welding without dead angles. The specific driving principles are existing technologies and will not be elaborated here. During welding, the first part to be welded 1 is installed inside the positioning groove 502. The dovetail protrusion on the rear side of the first part to be welded 1 is aligned with the right side stop block 4 of the chuck with the notch 401. Then, two second parts to be welded 2 are installed in the positioning holes 501 on the upper and lower sides. The left side stop block 3 and the right side stop block 4 of the chuck are respectively fitted onto the positioning pins through the corresponding second pin holes 12. The first part to be welded, 1, and the second part to be welded, 2 are positioned inside the chuck base 5. Then, the chuck base 5 is fitted onto the four guide pins 9, and the chuck base 5 is fixed to the welding machine fixture base 10 by two magnets 8. The positions are then fixed by the four guide pins on the welding base, and the two fixture parts are fixed together by magnets. After installation, the entire quick clamping fixture body is installed on the servo electric rotary chuck 100 by the welding fixture mold handle 11. The welding of three sides can be completed by the four-axis movement of the equipment. The welding efficiency is greatly improved by completing the welding of three sides in one go, thereby improving the utilization rate of the equipment and reducing the time of multiple clamping. Furthermore, multiple quick-clamping fixtures can be manufactured. The welding parts are clamped outside the machine. After welding one product, the quick-clamping fixture body along with the welded parts is removed, and the next quick-clamping fixture body with the welding parts is installed on the servo electric rotary chuck 100, so welding can continue. Multiple quick-clamping fixture bodies can be switched between production, improving work efficiency. Moreover, it is not necessary to remove the product after the previous process is completed and install the new product to be welded, thus effectively saving clamping time and improving work efficiency.
