Abstract
The invention provides a positioning part for an axial flow impeller. The positioning part is characterized in that a positioning part main body is formed through intersection of a cock body arranged in a hub clamp slot and a cock body arranged in a vane clamp slot; the two cock bodies comprise external surfaces and internal surfaces; the external surfaces and the internal surfaces have at least one intersecting line; and the hub clamp slot and the vane clamp slot which are matched with the cock bodies have displacement. The position of the vane relative to the disc is adjusted by adjusting the shape of the positioning part, namely changing the relative offset positions of the two cock bodies of the positioning part, thus realizing the adjustment of a plurality of angles on the basis of the existing angle.
Description
Technical field
The present invention relates to a kind of ventilation equipment accessory field, particularly a kind of axial-flow blower locating piece.
Background technique
The impeller blade mounting structure kind of axial-flow blower is a lot, the normal at present rivet arrangement that adopts, welded structure or integral die-cast structure, but adopt this mode to install, there is the shortcoming that the blade installation location is inaccurate and impeller performance can not be regulated, can not utilize the problem that angle is regulated the size of impeller air quantity and blast of adjusting, in order to address this problem often to adopt at present a plurality of locating slots are set in the groove of wheel hub, thereby and blade pass is crossed locating piece be stuck in different locating slots and realize adjustment blade angle, but because employed locating piece adopts cylindrical locating piece 1 ' as shown in Figure 1 mostly, therefore the angle that can regulate is limited, DeGrain.
Summary of the invention
At above problem, the present invention is by improving with the locating piece structure existing a kind of axial-flow blower, thereby under the situation that does not change the axial-flow blower wheel hub structure, by exchanging the axial-flow blower locating piece, can adjust blade angle, for reaching this purpose, the invention provides a kind of axial-flow blower locating piece, described locating piece main body is made up of with the cock body that is positioned at the blade draw-in groove is crossing the cock body that lays respectively in the wheel hub draw-in groove, described cock body comprises outer surface and internal surface, there is at least one intersection between described outer surface and the internal surface, and makes the wheel hub draw-in groove and the blade draw-in groove that cooperate with above-mentioned cock body produce displacement.
As a further improvement on the present invention, the radial cross-section of described cock body is semicircle or triangle or trapezoidal or profile of tooth, the radial cross-section of this patent cock body can be different cross section, and producer can carry out the locating piece of production outer surfaces according to wheel hub and blade locating slot inner surface structure.
The present invention is the shape by the adjustment locating piece, promptly changes the relativity shift position of two cock bodys of locating piece, adjusts the position of blade with respect to wheel hub plate to reach, thereby obtains numerous angular adjustment on the basis of existing angle.

Embodiment
Below in conjunction with drawings and Examples invention is described in detail:
The present invention is by improving with the locating piece structure existing a kind of axial-flow blower, thereby under the situation that does not change the axial-flow blower wheel hub structure, by exchange axial-flow blower locating piece, can adjust blade angle.
Fig. 3 is the structural representation of the embodiment of the invention 1, the locating piece that it is used for a kind of axial-flow blower blade, described locating piece main body 1 is made up of with the cock body 1-2 that is positioned at the blade draw-in groove is crossing the cock body 1-1 that lays respectively in the wheel hub draw-in groove, described cock body 1-1 comprises outer surface 1-1-1 and internal surface 1-1-2, described cock body 1-2 comprises outer surface 1-2-1 and internal surface 1-2-2, described outer surface 1-1-1 and internal surface 1-2-2, there are 2 intersections between internal surface 1-1-2 and the outer surface 1-2-1, and make the wheel hub draw-in groove and the blade draw-in groove that cooperate with above-mentioned cock body produce displacement, the cross section that is positioned at the cock body 1-1 of wheel hub draw-in groove is semicircle, and the cross section that is positioned at the cock body 1-2 of blade draw-in groove also is semicircle.
Fig. 4 is the structural representation of the embodiment of the invention 2, and its difference from Example 1 is that the cross section that is positioned at the cock body 1-1 of wheel hub draw-in groove is a triangle, and the cross section that is positioned at the cock body 1-2 of blade draw-in groove also is triangle.
Fig. 5 is the structural representation of the embodiment of the invention 3, and its difference from Example 1 is that the cross section that is positioned at the cock body 1-1 of wheel hub draw-in groove is trapezoidal, and the cross section that is positioned at the cock body 1-2 of blade draw-in groove also is trapezoidal.
Fig. 6 is the structural representation of the embodiment of the invention 4, and its difference from Example 1 is that the cross section that is positioned at the cock body 1-1 of wheel hub draw-in groove is a profile of tooth, and the cross section that is positioned at the cock body 1-2 of blade draw-in groove also is profile of tooth.
Fig. 7 is the structural representation of the embodiment of the invention 5, and its difference from Example 1 is that the cross section that is positioned at the cock body 1-1 of wheel hub draw-in groove is a triangle, and the cross section that is positioned at the cock body 1-2 of blade draw-in groove is trapezoidal.
