Fig. 2 is a three-dimensional block diagram of the present invention.
FIG. 3 is a cross-sectional view of a vane in the tooling of the present invention.
Fig. 4 is a structural view of the upper and lower positioning blocks of the present invention.
Fig. 5 is a diagram showing another construction of the present invention.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
The invention discloses a guide vane welding tool, which comprises a rotating shaft 200 and a fan-shaped blade 100 with a small arc surface and a large arc surface, wherein an arc groove 300 is formed in the small arc surface of the blade 100, a platform-shaped welding surface 400 is formed in the large arc surface, the tool for welding the blade 100 and the rotating shaft 200 comprises an upper positioning block 1, a lower positioning block 2, a pressing plate 3 and a screw 4, the upper positioning block 1 is in a circular ring shape, the lower positioning block 2 is in a cylindrical shape, the upper positioning block 1 is sleeved on the lower positioning block 2, a plurality of blades 100 are arranged in the upper positioning block 1, the blades 100 are spliced into a circular blade body 500, and a welding gap 800 is formed between the outer wall surface of the blade body 500 and the inner wall surface of the upper positioning block 1. The circular arc grooves 300 on the blade 100 are spliced into a circular through hole, and the circular through hole is positioned at the center of the blade body 500. The screw 4 sequentially passes through the pressing plate 3 and the circular through hole and is connected to the lower positioning block 2 in a threaded manner, and the pressing plate 3 presses the leaf surface body 500 on the lower positioning block 2. The plurality of rotating shafts 200 are connected to the upper positioning block 1 in a penetrating manner along the circumferential direction of the upper positioning block 1, and the inner end surface of each rotating shaft 200 extends into the welding gap 800 and abuts against the welding surface 400 of each blade 100.
