[0010] Preferably, the large gear meshes with the small ring gear, and the gear meshes with the large ring gear.

[0011] A method for using a welding device for fan production comprises the following steps: S1. First, place the central disc workpiece of the fan on the surface of the support platform, and then twist the telescopic rod 1. The telescopic rod 1 drives the rotating rod to rotate, and the rotating rod drives the large gear to rotate. When the large gear rotates, it drives the small gear ring to rotate. When the small gear ring rotates, it drives the vortex disk to rotate. When the vortex disk rotates, it drives the clamping blocks on the surface to gather toward the middle along the grain to clamp the disc workpiece. At the same time, the clamping blocks slide inside the support platform through the telescopic rod, and then all the fan blades are placed in the fan blade placement platform. The upper clamping plate is initially in the unfolded state. Press the upper clamping plate manually. After the upper clamping plate is pressed, it drives the sliding block to rotate, and Entering into the straight groove in the special-shaped chute, the upper clamping plate drives the extrusion block 1 to slide downward in the U-shaped chute, and the sliding block is limited and cannot rotate, and slides downward in the special-shaped chute. When the extrusion block 1 slides downward, it will squeeze the inclined surface of the clamping block 1. When the extrusion clamping block 1 is squeezed, it drives the spring rod to slide in the straight groove in the chute and the circulating chute until the extrusion block 1 slides over the clamping block 1, so that the plane of the clamping block 1 will clamp the plane of the extrusion block 1, and the extrusion block 2 will also slide downward at the same time and be clamped by the clamping block 2, so that the disc workpiece and the fan blade workpiece can be fixed at the same time, and welding can be carried out at the same time; S2. When the blade angle needs to be adjusted, the sliding ring can be manually rotated. When the sliding ring rotates, the round rod is driven to rotate. When the round rod is driven to rotate, the extrusion notch rod is driven, and the notch rod is driven to rotate. When the notch rod is driven to rotate, the rotating rod is driven to rotate. When the rotating rod is driven to rotate, the blade placement table is driven to rotate, and the four blade placement tables are rotated at the same time through the round rod, so that all the blades will deflect to the same angle at the same time, which is convenient for welding; S3. After welding is completed, rotate the telescopic rod 1 in the opposite direction. The telescopic rod 1 drives the rotating rod to rotate, and the rotating rod drives the large gear to rotate. When the large gear rotates, it drives the small gear ring to rotate. When the small gear ring rotates, it drives the vortex disk to rotate. When the vortex disk rotates, it drives the clamping blocks on the surface to spread outward along the grain to release the disc workpiece. At the same time, when the rotating rod rotates, it drives the gear to rotate. When the gear rotates forward, the teeth will be squeezed. When the teeth are squeezed, they will slide in the spring groove, so that the gear cannot mesh with the large gear ring. When the gear is reversed, the teeth cannot be squeezed, and it will mesh with the large gear ring, driving the large gear ring to rotate. When the large gear ring rotates, it drives the inclined surface extrusion block to rotate. When the inclined surface extrusion block rotates, it will squeeze the inclined surface Extrusion rod, when the inclined extrusion rod is squeezed, it will drive the spring rod to rotate. When the spring rod rotates, it will slide in the inclined groove in the circulating inclined groove and slide backward. When the spring rod slides backward, it will pull the clamping block 1 to slide backward until it is separated from the extrusion block 1, and at the same time drive the clamping block 2 to separate from the extrusion block 2. When the extrusion block 2 and the extrusion block 1 are not stuck, the spring 1 will push the upper clamping plate to slide upward, and at the same time drive the sliding block to slide upward inside the special-shaped slide groove. When the sliding block slides to the top, it will follow the inclined surface of the special-shaped slide groove, drive the upper clamping plate to rotate, and make the two upper clamping plates unfold, so that the entire welded workpiece can be taken out as a whole, which will save a lot of unlocking time; S4. At the same time, when the rotating rod rotates, it drives the ratchet to rotate. When the ratchet rotates forward, it cannot engage with the pawl, but when the ratchet rotates reversely, it engages with the pawl. At the same time, the rotating groove is driven to rotate through the pawl. When the rotating groove rotates, it drives the L-shaped rod to rotate. When the L-shaped rod rotates, it squeezes the sliding ring. When the sliding ring is squeezed, it drives the round rod to slide downward and pulls the notch rod. When the notch rod is pulled, it drives the rotating rod to reset, and at the same time drives the fan blade placement table to reset. When the notch rod is reset, it also drives the sliding ring to rotate and reset. Finally, pull the telescopic rod one to separate the ratchet and the pawl, so that the sliding ring is reset through the telescopic spring, and finally push the telescopic rod one back.

[0012] In the present invention, when the extrusion block 1 is squeezed, the spring rod is driven to slide in the straight groove in the slide groove and the circulating inclined groove until the extrusion block 1 slides over the clamping block 1, so that the plane of the clamping block 1 will clamp the plane of the extrusion block 1, and the extrusion block 2 will also slide downward at the same time and be clamped by the clamping block 2, so that the disc workpiece and the fan blade workpiece can be fixed at the same time, and welding can be carried out at the same time, saving time and improving efficiency.

[0013] In the present invention, the rotation of the round rod drives the extrusion notch rod, and drives the notch rod to rotate. The rotation of the notch rod drives the rotating rod to rotate. The rotation of the rotating rod drives the fan blade placement platform to rotate. The four fan blade placement platforms can rotate simultaneously through the round rod, so that all the fan blades will deflect to the same angle at the same time, which is convenient for welding and further improves the welding efficiency.

[0014] In the present invention, the sliding block slides upward inside the special-shaped slide groove. When the sliding block slides to the top, it will drive the upper clamping plate to rotate along the inclined surface of the special-shaped slide groove, so that the two upper clamping plates can be unfolded, so that the entire welded workpiece can be taken out as a whole, which will save a lot of unlocking time and further improve work efficiency.

First, place the central disc workpiece of the fan on the surface of the support platform 41, and then twist the telescopic rod 83, the telescopic rod 83 drives the rotating rod 42 to rotate, the rotating rod 42 drives the large gear 43 to rotate, the large gear 43 drives the small gear ring 45 to rotate, the small gear ring 45 drives the vortex disk 44 to rotate, the vortex disk 44 drives the surface clamping block 47 to gather toward the middle along the grain when the vortex disk 44 rotates, and the disc workpiece is clamped. At the same time, the clamping block 47 slides inside the support platform 41 through the telescopic rod 46, and then all the fan blades are placed in the fan blade placement platform 52. The upper clamping plate 55 is initially in the expanded state. The upper clamping plate 55 is manually pressed. After the upper clamping plate 55 is pressed, it drives the sliding block 513 to rotate and enters the special-shaped slide In the straight groove in the groove 512, the upper clamping plate 55 drives the extrusion block 1 515 to slide downward in the U-shaped slide groove 54, and the sliding block 513 is limited and cannot rotate, and slides downward in the special-shaped slide groove 512. When the extrusion block 1 515 slides downward, it will squeeze the inclined surface of the clamping block 1 57. When the extrusion clamping block 1 57 is squeezed, it drives the spring rod 59 to slide in the straight groove in the slide groove 56 and the circulating inclined groove 58 until the extrusion block 1 515 slides over the clamping block 1 57.

In this way, the disc workpiece and the fan blade workpiece can be fixed at the same time, and welding can be carried out at the same time, saving time and improving efficiency. S2. When the blade angle needs to be adjusted, the sliding ring 71 can be manually rotated. When the sliding ring 71 rotates, the round rod 73 is driven to rotate. When the round rod 73 rotates, the extrusion notch rod 516 is driven, and the notch rod 516 is driven to rotate. When the notch rod 516 rotates, the rotating rod 51 is driven to rotate. When the rotating rod 51 rotates, the blade placement platform 52 is driven to rotate, and the four blade placement platforms 52 are rotated at the same time through the round rod 73. In this way, all the blades will deflect to the same angle at the same time, which is convenient for welding and further improves the welding efficiency. S3.

When the extrusion block 2 514 and the extrusion block 1 515 are not stuck, the spring 1 517 will push the upper clamping plate 55 to slide upward, and at the same time drive the sliding block 513 to slide upward inside the special-shaped slide groove 512. When the sliding block 513 slides to the top, it will follow the inclined surface of the special-shaped slide groove 512 to drive the upper clamping plate 55 to rotate, so that the two upper clamping plates 55 are unfolded, so that the entire welded workpiece can be taken out as a whole, which will save a lot of unlocking time and further improve work efficiency. S4. At the same time, when the rotating rod 42 rotates, it drives the ratchet 84 to rotate. When the ratchet 84 rotates forward, it cannot engage with the pawl 82, but when the ratchet 84 rotates reversely, it engages with the pawl 82. At the same time, the rotating groove 81 is driven to rotate through the pawl 82. When the rotating groove 81 rotates, it drives the L-shaped rod 85 to rotate. When the L-shaped rod 85 rotates, it squeezes the sliding ring 71. When the sliding ring 71 is squeezed, it drives the round rod 73 to slide downward and pulls the notch rod 516. When the notch rod 516 is pulled, it drives the rotating rod 51 to reset, and at the same time drives the fan blade placement platform 52 to reset. When the notch rod 516 is reset, it also drives the sliding ring 71 to rotate and reset.

8. A method for using a welding device for fan production, using the welding device for fan production as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1. First, place the central disc workpiece of the fan on the surface of the support platform (41), and then twist the telescopic rod (83). The telescopic rod (83) drives the rotating rod (42) to rotate, and the rotating rod (42) drives the large gear (43) to rotate. When the large gear (43) rotates, it drives the small gear ring (45) to rotate. When the small gear ring (45) rotates, it drives the vortex disk (44) to rotate. When the vortex disk (44) rotates, it drives the clamping block (47) on the surface to gather toward the middle along the grain to clamp the disc workpiece. At the same time, the clamping block (47) slides inside the support platform (41) through the telescopic rod (46), and then all the fan blades are placed in the fan blade placement platform (52). The upper clamping plate (55) is initially in the unfolded state. The upper clamping plate (55) is manually pressed. After the upper clamping plate (55) is pressed, it drives the sliding block (513) to rotate, and Entering into the straight groove in the special-shaped slide groove (512), the upper clamping plate (55) drives the extrusion block 1 (515) to slide downward in the U-shaped slide groove (54), and at the same time, the sliding block (513) is limited and cannot rotate, and at the same time slides downward in the special-shaped slide groove (512). When the extrusion block 1 (515) slides downward, it will squeeze the inclined surface of the clamping block 1 (57). When the extrusion clamping block 1 (57) is squeezed, it drives the spring rod (59) to slide in the straight groove in the slide groove (56) and the circulating inclined groove (58) until the extrusion block 1 (515) slides over the clamping block 1 (57), so that the plane of the clamping block 1 (57) will clamp the plane of the extrusion block 1 (515), and at the same time, the extrusion block 2 (514) will also slide downward at the same time and be clamped by the clamping block 2 (510), so that the disc workpiece and the fan blade workpiece can be fixed at the same time and welding can be carried out at the same time; S2. When the blade angle needs to be adjusted, the sliding ring (71) can be manually rotated. When the sliding ring (71) rotates, the round rod (73) is driven to rotate. When the round rod (73) is driven to rotate, the extrusion notch rod (516) is driven, and the notch rod (516) is driven to rotate. When the notch rod (516) is driven to rotate, the rotating rod (51) is driven to rotate. When the rotating rod (51) is driven to rotate, the blade placement platform (52) is driven to rotate. The four blade placement platforms (52) are driven to rotate simultaneously through the round rod (73). In this way, all the blades are deflected to the same angle at the same time, which is convenient for welding. S3. After welding is completed, the telescopic rod (83) is rotated in the opposite direction. The telescopic rod (83) drives the rotating rod (42) to rotate. The rotating rod (42) drives the large gear (43) to rotate. When the large gear (43) rotates, the small gear ring (45) is driven to rotate. When the small gear ring (45) rotates, the vortex disk (44) is driven to rotate. When the vortex disk (44) rotates, the clamping blocks (47) on the surface are spread outward along the lines to release the disc workpiece. At the same time, when the rotating rod (42) rotates, the clamping blocks (47) on the surface are driven to rotate. The movable gear (66) rotates, and when the gear (66) rotates forward, the teeth (64) are squeezed. When the teeth (64) are squeezed, they slide in the spring groove (63), so that the gear (66) cannot mesh with the large ring gear (61). When the gear (66) rotates reversely, the teeth (64) cannot be squeezed, and it will mesh with the large ring gear (61), driving the large ring gear (61) to rotate. When the large ring gear (61) rotates, the inclined surface squeezing block (62) is driven to rotate, and the inclined surface squeezing block (62) rotates. When the inclined extrusion rod (65) moves, it will squeeze the inclined extrusion rod (65). When the inclined extrusion rod (65) is squeezed, it will drive the spring rod (59) to rotate. When the spring rod (59) rotates, it will slide in the inclined groove in the circulation inclined groove (58) and slide backward. When the spring rod (59) slides backward, it will pull the clamping block (57) to slide backward until it is separated from the extrusion block (515), and at the same time drive the clamping block (510) to separate from the extrusion block (514). The extrusion block (514) and the extrusion block (514) are separated. When (515) is not stuck, spring 1 (517) will push the upper clamping plate (55) to slide upward, and at the same time drive the sliding block (513) to slide upward inside the special-shaped slide groove (512). When the sliding block (513) slides to the top, it will follow the inclined surface of the special-shaped slide groove (512) to drive the upper clamping plate (55) to rotate, so that the two upper clamping plates (55) can be unfolded, so that the entire welded workpiece can be taken out as a whole, which will save a lot of unlocking time; S4. When the rotating rod (42) rotates, the ratchet wheel (84) is driven to rotate. When the ratchet wheel (84) rotates forward, it cannot mesh with the pawl (82). However, when the ratchet wheel (84) rotates reversely, it meshes with the pawl (82). At the same time, the pawl (82) drives the rotating groove (81) to rotate. When the rotating groove (81) rotates, the L-shaped rod (85) is driven to rotate. When the L-shaped rod (85) rotates, it squeezes the sliding ring (71). When the sliding ring (71) is squeezed, it drives the round rod (71). 3) Slide downward and pull the notch rod (516). When the notch rod (516) is pulled, the rotating rod (51) is driven to reset, and the fan blade placement platform (52) is driven to reset. When the notch rod (516) is reset, the sliding ring (71) is driven to rotate and reset. Finally, the telescopic rod (83) is pulled to separate the ratchet (84) from the pawl (82), so that the sliding ring (71) is reset through the telescopic spring (72), and finally the telescopic rod (83) is pushed back.
