Description

Technical Field

[0001] The invention relates to the technical field of fan impeller welding production, and in particular to a welding device for processing impellers used for processing fan accessories. Background Art

[0002] A fan is a mechanical device used to transport gas. It increases the energy of the gas by working on the gas through rotating parts such as impellers, thereby achieving functions such as gas transportation, ventilation, and dust removal. During the impeller production process, the disc and blades need to be connected together through assembly or welding. Depending on the needs of use, the welding installation angle of the blades will also be different.

[0003] During the impeller welding process, the wheel disc and the blades are usually pre-joined by splicing, and then the joint between the two is welded to improve the service strength of the impeller. However, manual welding is currently mostly used. Since the height of the welding head from the joint will cause deviations in welding height and position due to manual operation, the welding effect varies.

A sleeve plate 41 and a hydraulic cylinder 42 are provided on the base 4 on the top surface of the transverse seat 2004. The plug plate 5 on the top of the sleeve plate 41 is adjusted and retracted by the movement of the output shaft of the hydraulic cylinder 42, so as to assist in adjusting the height position of the cantilever frame 6 according to the height of different weld positions. The output shaft of the third motor 52 on the inner top surface of the plug board 5 drives the mounting frame 521 to rotate, and adjusts the angle of the cantilever frame 6, so that the stabilizing frames 61 on both sides of the cantilever frame 6 can cooperate with the opposite sides of the insertion blade 3002 when the base 4 moves and adjusts; The reciprocating wire shaft A601 and the reciprocating wire shaft B602 at both ends of the side of the cantilever frame 6 rotate under the action of the gear box 62 and the related transmission structure. The fourth motor 621 drives the internal structure of the gear box 62 to rotate. The transmission shaft A6201 and the transmission shaft B6202 at the output ends of both sides of the gear box 62 rotate synchronously at the same speed. When the transmission shaft B6202 rotates forward, it drives the reciprocating wire shaft B602 to rotate. At the same time, the reciprocating wire shaft A601 can also rotate synchronously, and synchronously cooperate with the reciprocating wire shaft B602 to adjust the position of the moving frame 64; As the welding assembly 8 on the mobile frame 64 moves, the roller 802 at the end of the synchronous frame 801 in the welding assembly 8 contacts the surface of the blade 3002, and the angle and height of the welding machine 804 acting on the weld are accurately controlled. The return spring 803 on the inner side of the end of the synchronous frame 801 cooperates with the spring cylinder 641 on the mobile frame 64, and as the arc shape of the surface of the blade 3002 changes, the position of the welding head at the bottom of the welding machine 804 is adjusted, so that the welding machine 804 always acts on the weld position for welding; When a blade 3002 is welded, first allow the roller 802 to roll from the side surface of the blade 3002 to the side surface of the pad block 711, then through the coordinated cooperation of the base 4 and the third motor 52, allow the stabilizing frame 61 to withdraw from the side of the blade 3002, and then adjust the next blade 3002 to the welding position by rotating the placement plate 1, and adjust the contact position between the pad block 711 and the end face of the blade 3002 through the reciprocating wire shaft C7 and other structures on the inner side of the cantilever frame 6, so as to facilitate the alignment operation of the next blade 3002 with the pad block 711, and allow the roller 802 to roll from the side surface of the pad block 711 to the side surface of the blade 3002, so as to prepare for the welding of the next blade 3002.
