A kind of turbine disk assembling assembly blade installation site measurement apparatus
The invention belongs to aerial motor spare part detection technique field, more particularly to a kind of turbine disc assemblies blade dress
With position-measurement device.
Turbine disc assemblies largely influence engine performance, need to check leaf position in blade process is installed
It is whether qualified.By measuring on blade edge template face radius at a bit, the accuracy of blade installation site can be reflected.Due to every
, there is bounce in the difference between individual blade, difficulty is brought to positioning measurement between listrium end face；By installing, blade quantity is more, group
The factor influence such as part volume is big, it is more time-consuming using three-dimensional coordinates measurement.
The content of the invention
In order to solve the above technical problems, purpose of the invention is to provide a kind of simple, accurate measurement apparatus, specific skill
Art scheme is as follows：
A kind of turbine disk assembling assembly blade installation site measurement apparatus, including measurement assembly and positioning component；It is described fixed
Hyte part includes main body, and the main body has and is mutually 120 degree of the three of angle support arms, and gathering sill is set in the support arm, described to lead
To expansion link is set in groove, one end of expansion link is tapering point, and the tapering point is abutted with cone, and the cone upper end sets outer
Screw thread, the external screw thread and nut screw connection；The other end of the expansion link is set with cantilever, the termination of the cantilever is fixed with
2 bearings of right-angled intersection；The measurement assembly includes the pole being fixed in main body, and table folder, institute are also set up on the pole
State and limited block is set on table folder, limited block can be slided in table folder, the difference marking line of limited block both sides；Measurement table is arranged on branch
The end of bar.
To realize the resilience after measurement, the expansion link is two-part, two intersegmental setting extension springs.
It is an advantage of the invention that：This device breaches the listrium end that turbine disc assemblies are caused in assembling process Leaf difference
The influence beated between face to positioning measurement, realize fast and stable measurement, and can multistage turbine disk component it is general.This structure is new
Grain husk, using reliability, scene feedback application is good, and certainty of measurement meets technological requirement, and substantially increases the measurement effect of part
Rate, measurement result can reflect the actual position of part, contribute to the control to product quality.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is location structure schematic diagram；
Fig. 4 is working state schematic representation；
The present invention is illustrated below in conjunction with the accompanying drawings, and as Figure 1-Figure 4, the present invention includes main body 10, expansion link 2, spiral shell
Female 3, cantilever 4, bearing 5, fulcrum bar component 6, table folder 7, limited block 8, measurement table 9；Main body 10 has three support arms for being mutually 120 °
101, gathering sill is set in support arm 101, three identical expansion links 2 are arranged in three gathering sills 101, are fixed by cover plate 11, stretch
Extension spring 31 is housed in contracting bar 3, resilience after measurement is realized.The upper end of cone 1 is external screw thread, through after the through hole of the center of main body 10
It is connected with nut 3, rotation nut 3 realizes that cone is moved up and down.Cone 1 is brought into close contact with three expansion links 2 by tension spring, cone
Body 1 is moved up, and expansion link 2 is displaced outwardly.2 bearings of right-angled intersection are installed by two screws in the every outside of expansion link 2
5.Expansion link 2 is displaced outwardly, and drives cantilever 4, bearing 5 to move, and the bearing 5 to horizontal level is fitted with tested part, while by
In gravity, vertically disposed bearing 5 is brought into close contact with tested part end face, realizes the positioning of device.Whole process is controlled by nut 3
System, and ensure that device of the invention can rotate around the internal circumference of tested part by bearing 5.
Fulcrum bar component 6 is connected with the interference fit of main body 10, and is equipped with pin anti-rotation.Fulcrum bar component is by pole, clip, tangential
The parts such as clamping composition, measurement assembly is exported to position to be measured, and pilot process can carry out multiple degrees of freedom adjustment.Measurement table 9 is led to
Cross screw, bushing to be connected with table folder 7, table folder 7 is arranged on fulcrum bar component 6.No. 8 limited blocks can be slided in table folder 7, both sides point
Other marking line, is exactly the height value of limited block and measurement table after aligning.Adjustment fulcrum bar component 6, limited block is adjacent to tested part
Afterwards, the accurate location of measurement is as needed, thereafter through screw lock pole 6.After this process, limited block 8 is moved to and is not done
Relate to position and lock, rotating mass 10 realize the circumferential measurement under the blade listrium height.
