Abstract
The invention discloses a positioning piece for an axial flow impeller. A positioning piece main body is formed by staggering and intersecting a cock body positioned in a hub clamp groove and a cock body positioned in a blade clamp groove respectively and ensures that the hub clamp groove and the blade clamp groove which are matched with the cock bodies generate displacement. The position of a blade relative to a disk is adjusted by adjusting the shapes of the cock bodies, namely changing the relative offset positions of the two cock bodies, so that countless angle adjustment can be obtained on the basis of the conventional angle.

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 of not improving 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 the locating piece that a kind of axial-flow blower blade is used, described locating piece main body is interlaced crossing the composition with the cock body that is positioned at the blade draw-in groove by the cock body that lays respectively in the wheel hub draw-in groove, and wheel hub draw-in groove and blade draw-in groove that above-mentioned cock body is cooperated 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 produce the locating piece of corresponding radial cross section according to wheel hub and blade locating slot inner surface structure.
As a further improvement on the present invention, the radial cross-sectional shape of described 2 cock bodys is inequality, the cross-sectional sizes difference of the radial cross-section of 2 cock bodys, the radial cross-section of 2 cock bodys of this patent can be the same or different, cross-sectional sizes can be identical also can be inequality, producer can select corresponding radial cross section to produce according to actual conditions.
The present invention is the shape by the adjustment cock body, promptly changes the relativity shift position of two cock bodys of cock body, adjusts the position of blade with respect to dish to reach, thereby obtains numerous angular adjustment on the basis of existing angle.
