Description
Technical field
The present invention relates to a kind of three-dimensional measuring apparatus, particularly a kind of for measuring the device of coordinates of curved column for impeller blade of centrifugal pump, belong to three-dimension curved surface dimension survey field.
Background technique
When needs detect impeller vane of centrifugal pumps or carry out reverse-engineering when imitated, conventionally need to survey and draw out the three-dimensional dimension of impeller, particularly, in the time that blade is irregular curved surface, need to measure with professional surveying and mapping tool the three-dimensional dimension of blade.The professional technique of painting of impeller waterpower drawing utilizes three-dimensional cylindrical coordinates to represent exactly.
By measuring spoon of blade cylindrical coordinates, can check impeller mold whether to meet drawing size standard; Can check Foundry Production blade out whether to meet drawing size standard.Particularly, in the time carrying out reverse-engineering imitation, can survey and draw out the measurements of the chest, waist and hips size of impeller for the production of casting.
Cylindrical coordinates three-dimensional measurement is to measure complex-curved basic skills.Cylindrical coordinates three-dimensional measurement is first positioned an initial point, then measures with respect to the radius R of initial point, angle [alpha] °, height Z value: (R, α °, Z).
Cylindrical coordinates three-dimensional measurement uses basic measuring tool to manually locate measurement conventionally.These basic measuring tools as shown in Figure 1, use beam calliper, little slide calliper rule, depth gauge, height gauge.Utilize beam calliper to look for axle center to impeller, and do supporting surface; Rule on front shroud of impeller with little slide calliper rule, look for angle line α °; With depth gauge take beam calliper as reference level on blade contouring Z, and read radius R with the scale of beam calliper; At front side of vane contouring Z, and find out the radius of front side of vane with depth gauge with height gauge.
The process that manual positioning is measured is as follows:
1. look for a block length bar shaped plank to be stuck on impeller eye end face;
2. measure inlet diameter with beam calliper;
3. find out impeller center with beam calliper, and central point is marked on batten;
By beam calliper square on impeller eye, and make on one side through central point all the time;
5. depth gauge is vertically pressed on beam calliper all the time;
6. mobile beam calliper and depth gauge respectively, finds out 0 ° of start line of blade;
7. 0 ° of start line of mark leafing sheet on impeller eye edge;
8. calculate the chord length of every 10 °, with lesser calorie chi mark 10 °, 20 °, 30 °～～～;
On depth gauge often to get identical h value as isohypse, make beam calliper along angle line direction, manual mobile depth gauge makes the end of depth gauge crossing with blade surface, owing to there being scale on beam calliper, reads value now, has just found out radius R.
Due to the impeller center, location of this process, beam calliper is positioned perpendicular to the needs of work such as beam calliper are manual through angle line, depth gauge through center, beam calliper, error is quite large, measures very difficult, has affected greatly measuring accuracy and efficiency.
