Restriction as to above technological scheme: described base is cylindrical plate, the axis of its axis hole and the dead in line of base.
As another restriction to above technological scheme, described base is drum-shaped, connects into entirety by cylindrical body and cylindrical diapire, and the end face of described cylindrical body is plane, the middle part of described diapire is provided with axes normal in the axis hole of the end face of cylindrical body, installs cylindrical body oblique crank Z in described axis hole.
Illustrate: the number of positioning box is determined according to the quantity of the blade on impeller, general three to six; A kind of assembling and detection device are only applicable to the impeller of a model.
Beneficial effect: this device correctly can be determined the relative position of blade and wheel hub and is fixed up by this correct relative position, then by blades installation on wheel hub; During detection, each block blade is put into the positioning box of this device, and wheel hub is sleeved on the cylindrical body oblique crank Z of this device, if the space that the positioning box that the peak of all blades does not exceed place surrounds, then illustrate that this impeller is qualified.This apparatus structure is simple, easy to use, can ensure quality of product, raise labour productivity

Embodiment
Below in conjunction with Fig. 1 to Fig. 6, the utility model is described in further detail: a kind of assembling of draught fan impeller and detection device, it is characterized in that: base 1 is set, the end face of described base 1 is plane, described base 1 is provided with the tubular axis hole of the end face perpendicular to base, installs cylindrical body oblique crank Z 2 in described axis hole; Arrange multiple positioning box, described each positioning box is Kei-shaped, respectively connects into entirety by one piece of base plate, 4, one piece of end plate 5 and two blocks of side plates 3; Described base plate 4, end plate 5 and side plate 3 are all cuboid shape thin plates; Described end plate 5 and side plate 3 are perpendicular to base plate 4, and described end plate 5 is perpendicular to side plate 3; The shape of described each positioning box is identical, size is equal; Described multiple positioning box is arranged on the end face of base 1, it is petal that multiple positioning box is uniformly distributed into centered by cylindrical body oblique crank Z 2, one end of end plate 5 is not installed near cylindrical body oblique crank Z 2, the center line of each positioning box and the axes intersect of cylindrical body oblique crank Z 2, the centerline bisects of multiple positioning box 360 °, the inner side surface of the end plate 5 of each positioning box is equal with the distance of the axis of cylindrical body oblique crank Z 2.
Described base 1 is cylindrical plate, the axis of its axis hole and the dead in line of base 1.
Described base 1 is drum-shaped, connects into entirety by cylindrical body and cylindrical diapire, and the end face of described cylindrical body is plane, and the middle part of described diapire is provided with axes normal in the axis hole of the end face of cylindrical body, installs cylindrical body oblique crank Z 2 in described axis hole.
Blade adopts special equipment mass-producted, and therefore the shape of qualified blade is identical, size is equal.Shape mentioned here is identical, size is equal, refers to that, in the scope of tolerance permission, definitely identical blade does not have.When impeller is placed in the horizontal plane, blade projection in the horizontal plane has the widest position and the widest size, and in this, as the width of base plate, and the size marked on parts drawing is as the foundation calculated; In like manner, determine the height of side plate and end plate according to the projection of blade on vertical plane, the size also marked on parts drawing is as the foundation calculated; According to the length of blade and the external diameter of wheel hub, determine the distance of the axis of end plate inner side surface and cylindrical body oblique crank Z, according to the Size calculation that parts drawing marks.Determine the size of positioning box, also will consider tolerance.When being loaded in positioning box by one piece of blade, blade and positioning box have at least four points to contact, and every block blade is all identical with the contact condition of positioning box; Positioning box covers larger flat board, then has distance between blade and this larger flat board, but this distance is in the scope that tolerance allows; Or the end face of this larger flat board and positioning box has gap, but this gap is in the scope that tolerance allows.According to this device that the shape of impeller and the size of design are produced, correct relative position between every block blade and wheel hub can be determined and is fixed up in this tram.Using method is: every block blade is loaded positioning box and makes it contact with biside plate with base plate, end plate, then covers each positioning box with one piece of larger flat board; Wheel hub is sleeved on cylindrical body oblique crank Z, but with bolt, blade is fixed on wheel hub again.In order to prevent making the relative position of certain block blade and wheel hub change because of carelessness when installing blade, after assembling, need the gap seen between the end face of larger flat board and each positioning box, if this gap exceedes the tolerance range of regulation, then assemble defective, need blade protruding upward to disassemble to reinstall.By blades installation on wheel hub, the method also using welding had, this method is generally applicable to installing less impeller.
There are two kinds of bases in the present embodiment, are a kind ofly applicable to by blades installation on the cylndrical surface of wheel hub, another kind of to be applicable to blades installation on the end face of wheel hub.
