Abstract
The present invention relates to the preparation methods that a kind of turbo blade wall thickness detects control tooling, the specific steps are as follows: makes the 3D model of turbo blade；According to the 3D model of the 3D model of the 3D modelling leaf basin of turbo blade and blade back, the 3D model of the leaf basin is bonded completely with the concave surface of turbo blade；The 3D model of the blade back is bonded completely with the convex surface of turbo blade；Detection hole is made on the 3D model of leaf basin and the 3D model of blade back；The 3D model of leaf basin for being equipped with detection hole and the 3D model of the blade back equipped with detection hole are printed using 3D printing technique.Method fabrication cycle of the invention is short (can be successful within 1-5 days), and the tooling made can not only quickly and effectively determine the position of blade wall thickness test point, and be applicable not only to the detection of casting section thickness, is also applied for the detection of wax-pattern wall thickness.
Description
Technical field
The present invention relates to precision-investment casting fields, and in particular to a kind of preparation of turbo blade wall thickness detection control tooling
Method.
Background technique
Turbo blade precision casting requires detection wall thickness, existing wall thickness detection in designated position according to the requirement of drawing
Point finds test point using scribing line, three coordinate measurements or using metal tooling, and blade construction is the cambered surface of distortion, scribing line and three
There are deviation, detection efficiency is low for mark detection；The metal frock making period is long, and metal tooling is only capable of detection casting, takes gold
It is easy to scratch wax-pattern of damaging when belonging to tooling detection wax-pattern.
Summary of the invention
It is an object of the invention to: a kind of preparation method of turbo blade wall thickness detection control tooling, party's legal system are provided
Make that the period is short, the tooling made can not only quickly and effectively determine the position of blade wall thickness test point, and not only fit
For the detection of casting section thickness, it is also applied for the detection of wax-pattern wall thickness.
To achieve the goals above, the invention provides the following technical scheme:
A kind of preparation method of turbo blade wall thickness detection control tooling, the specific steps are as follows:
S1: the 3D model of turbo blade is made；
S2: according to the 3D model of the 3D model of the 3D modelling leaf basin of turbo blade and blade back, the leaf basin
3D model is bonded completely with the concave surface of turbo blade；The 3D model of the blade back is bonded completely with the convex surface of turbo blade；
S3: detection hole is made on the 3D model of leaf basin and the 3D model of blade back；
S4: the 3D model of the leaf basin of detection hole and the 3D model of the blade back equipped with detection hole will be equipped with using 3D printing technique
It prints.
Preferably, the described turbo blade wall thickness detection control tooling with a thickness of 0.5-5mm.
Preferably, the detection hole is cylindrical hole, and the partial size of detection hole is φ 0.5-5mm.
Preferably, the raw material of the 3D printing is resin.
The beneficial effects of the present invention are:
Method fabrication cycle of the invention is short (can be successful within 1-5 days), and the tooling made can not only be quick
The effective position for determining blade wall thickness test point, and it is applicable not only to the detection of casting section thickness, it is also applied for wax-pattern wall thickness
Detection.
Detailed description of the invention:
Fig. 1-3 is the structural schematic diagram of the leaf basin different angle equipped with detection hole；
Fig. 4-6 is the structural schematic diagram of the blade back different angle equipped with detection hole.
Specific embodiment
A kind of preparation method of turbo blade wall thickness detection control tooling, it is characterised in that: specific step is as follows:
S1: the 3D model of turbo blade is made；
S2: according to the 3D model of the 3D model of the 3D modelling leaf basin of turbo blade and blade back, the leaf basin
3D model is bonded completely with the concave surface of turbo blade；The 3D model of the blade back is bonded completely with the convex surface of turbo blade；
S3: detection hole is made on the 3D model of leaf basin and the 3D model of blade back；
S4: the 3D model of the leaf basin of detection hole and the 3D model of the blade back equipped with detection hole will be equipped with using 3D printing technique
It prints.
Wherein, turbo blade wall thickness detection control tooling with a thickness of 0.5-5mm.
Detection hole is cylindrical hole, and the partial size of detection hole is φ 0.5-5mm.
The raw material of 3D printing is resin.
When actually detected, the leaf basin for being equipped with detection hole is fitted with the blade back for being equipped with detection hole with turbo blade, then
It marks at the corresponding turbine vane position of detection hole, finally, using ultrasound examination wall thickness.
