Abstract
The invention discloses an axial-flow fan blade detecting device. The axial-flow fan blade detecting device comprises a standard table (1), wherein the upper surface of the standard table (1) is a plane; the upper surface of the standard table (1) is provided with a blind hole (2), a scaleplate (4) and an annular groove (3); the annular groove is formed around the blind hole (2) and is used for fixing a hub of axial-flow fan blades; a bearing (5) which is in inserted connection with a rotating shaft on the hub of the axial-flow fan blades is arranged in the blind hole (2); a slide track (6) which extends from the annular groove (3) to the edge of the standard table (1) is arranged on the upper surface of the standard table (1); the scaleplate (4) is slidably arranged on the slide track (6); and the axis of the bearing (5) and the scaleplate are perpendicular to the upper surface of the standard table (1). By the axial-flow fan blade detecting device, whether the lowest axial points of the produced axial-flow fan blades are positioned on the same plane or not can be judged, and the distance between the lowest axial point and the highest axial point of each blade is detected.
Description
Technical field
The present invention relates to a kind of axial-flow leaf pick-up unit.
Background technology
Axial-flow leaf generally comprises wheel hub and is arranged on several blades on wheel hub outer circumference surface, one end of wheel hub is provided with the rotating shaft for connecting rotor, when rotating shaft is placed down, require the axial minimum point of each blade of axial-flow leaf at grade, and have strict requirement to the distance between the axial minimum point of each blade and axial peak, be at present by production technology strictly control ensure above-mentioned requirements, and also do not have at present a kind of device can be used for whether distinguishing at grade the axial minimum point of each blade of the axial-flow leaf produced and axial peak, each sharf detects to the distance between minimum point and axial peak, make to learn that whether the axial-flow leaf produced is qualified, performance when axial-flow leaf uses cannot be ensured.
Summary of the invention
Technical matters to be solved by this invention is, provide can to the axial minimum point of each blade of the axial-flow leaf produced whether at grade, a kind of axial-flow leaf pick-up unit of detecting to the distance between minimum point and axial peak of each sharf.
For solving the problems of the technologies described above, a kind of axial-flow leaf pick-up unit provided by the invention, it comprises a standard station, the upper surface of standard station is plane, the upper surface of standard station is provided with a blind hole, one for measure the distance between the axial minimum point of the blade of axial-flow leaf and axial peak scale and arrange centered by blind hole one for the annular groove of the wheel hub of fixing axial-flow leaf, the bearing of a rotating shaft on the wheel hub of grafting axial-flow leaf is provided with in blind hole, the upper surface of described standard station is provided with the slide rail at the edge extending to standard station from annular groove, described scale is slidably arranged on slide rail, the axis of bearing is arranged with scale is all vertical with the upper surface of reference disk.
After adopting above structure, the present invention compared with prior art, has following advantage:
When the axial-flow leaf produced is detected, standard station horizontal positioned, the rotating shaft of one end of the wheel hub of axial-flow leaf is inserted in bearing fixing, make the wheel hub of axial-flow leaf be fixed in annular groove simultaneously, the axial minimum point of blade and the upper surface of standard station are offseted, if now vaned axial minimum point all offset with the upper surface of standard station, then can learn the axial minimum point of each blade at grade, then wheel hub is rotated, each blade is made to turn to scale place one by one, the axial peak making scale can measure each blade is one by one to the axial peak of the upper surface distance of standard station and blade to the distance of axial minimum point, can learn whether the axial peak of blade meets the requirements to the distance of axial minimum point, if the axial minimum point of any one blade does not offset with the upper surface of standard station or the axial peak of any one blade is undesirable to the distance of axial minimum point, then this axial-flow leaf is defective, whether qualifiedly axial-flow leaf can be effectively detected by this axial-flow leaf pick-up unit, ensure performance when axial-flow leaf uses, and be slidably arranged on slide rail due to scale, make scale can be used for measuring the axial-flow leaf of different size, use more for convenience.
As improvement, described standard station is the disk be made up of No. 45 steel; Make standard station surface more smooth, flatness is better, more accurate during measurement, and intensity is higher.
As improvement, the thickness of described standard station is 2 ~ 5 centimetres; Make the rotating shaft on the wheel hub of axial-flow leaf to insert in blind hole completely, make axial-flow leaf fixation, and make standard station lighter in weight, be convenient to carrying.
