Abstract
The invention discloses a method and an apparatus for determining the center of a casting impeller. The apparatus comprises two supports (1), and guide bars (2) horizontally penetrate through the two supports (1). An adjustment screw (3) is arranged to pass through the supports (1) in the middle. A movable wedge block (4) cooperating with a work piece (8) is disposed on the upper part of each support (1), and a cross bar (6) horizontally passing through the two supports is arranged above the wedge blocks (4). A central reference slot (5) is arranged in the cross bar (6), and a marking needle (7) can slide to the left and the right in the central reference slot (5). A plurality of theoretical central lines are marked on a casting impeller by means of the marking needle. Intersection points of the plurality of theoretical central lines form an intersection point zone, and a point in the zone is picked as the center of the casting impeller for carrying out subsequent finishing. According to the technical scheme, the number of unqualified products can be minimized, and the yield is maximized.
Description
Technical field
The present invention relates to the processing and manufacturing field of mechanical field parts, method and the device at especially a kind of definite casting impeller class center.
Background technology
The impeller of some high-speed cruisings requires to operate steadily, shake little, and requirement for dynamic balance is high, and these impeller blanks are generally sprays, through finishing, transient equilibrium detect qualified after, just can come into operation.After impeller has been cast, in the time carrying out finishing, be often difficult to accurately determine the practical center of impeller, the dynamic balance of impeller after processing can not meet the demands, and causes scrapping in a large number of product.So must accurately mark the practical center that marks impeller casting before processing, use for finishing, farthest reduce unacceptable product, improve yield rate.
Summary of the invention
The invention provides a kind of method and device, in impeller finishing, can fast go out the center of impeller casting.
The method at definite casting impeller center, chooses the removable wedge shape piece identical with impeller blade shapes, angle is consistent; Removable wedge shape piece is arranged on the bracing frame of adjustable movement; Manual adjustments adjusting screw(rod), fits the position of mobile wedge and impeller, clamping work pieces completely; Scriber horizontally slips in center reference groove, marks theoretical centerline on workpiece; Unclamp workpiece, turning of work piece, make to fit tightly with removable wedge shape piece after an angle of workpiece rotation, clamping work pieces marks another theoretical centerline on workpiece, and two theoretical centerlines meet at a bit; Repeat above-mentioned turning of work piece angle, mark the step of theoretical centerline; An intersection area of intersection point composition of many theoretical centerlines, chooses a central point of this intersection area as the center of this impeller.
The device at a kind of definite casting impeller center, it comprises two bracing frames 1, the horizontal cross that is provided with bracing frame 1 runs through the guide rod 2 of two bracing frames 1, the middle part of bracing frame 1 is provided with the adjusting screw(rod) 3 that horizontal cross runs through two bracing frames 1, the top of bracing frame 1 is provided with the removable wedge shape piece 4 coordinating with workpiece 8, the top of removable wedge shape piece 4 is provided with the cross bar 6 that horizontal cross runs through two stands, and described cross bar 6 is provided with center reference groove 5, and scriber 7 can horizontally slip in center reference groove 5.
Described removable wedge shape piece 4 is consistent with shape and the angle of workpiece 8 impeller blades, and removable wedge shape piece 4 is movably connected on support frame as described above 1.
By technical scheme of the present invention, change the mode of determining impeller casting center in prior art by the mode of range estimation, by the intersection point of many theoretical centerlines, determined the center of impeller casting, improve the precision in subsequent fine process, improved yield rate.
