A kind of turbine disk assembling assembly blade installation site measuring device
The invention belongs to aerial motor spare part detection technique fields, fill more particularly to a kind of turbine disc assemblies blade
With position-measurement device.
Turbine disc assemblies largely influence engine performance, need to check leaf position in installation blade process
It is whether qualified.By measurement blade edge template face on a little at radius, can reflect the accuracy of blade installation site.Due to every
There is bounce between listrium end face, bring difficulty to positioning measurement in the difference between a blade；The more, group by installation blade quantity
The factors such as part volume is big influence, more time-consuming using three-dimensional coordinates measurement.
Summary of the invention
In order to solve the above technical problems, purpose of the invention is to provide a kind of simple, accurate measuring device, specific skill
Art scheme is as follows:
A kind of turbine disk assembling assembly blade installation site measuring device, including measurement component and positioning component；It is described fixed
Hyte part includes main body, and the main body has three support arms for being mutually 120 degree of angles, and guide groove is arranged in the support arm, described to lead
Telescopic rod is set into slot, and one end of telescopic rod is tapered end, and the tapered end is abutted with cone, and the cone upper end setting is outer
Screw thread, the external screw thread and nut cooperate；The other end of the telescopic rod is fixed with cantilever, the end setting 2 of the cantilever
The bearing of a right-angled intersection；The measurement component includes the strut being fixed in main body, and table folder is also set up on the strut, described
Limited block is set in table folder, and limited block can slide in table folder, and marking scribing line is distinguished on limited block both sides；Table is measured to be arranged in strut
End point；Rotating nuts realize that cone moves up and down；Telescopic rod is displaced outwardly, and drives cantilever, bearing mobile, until horizontal position
Bearing be bonded with tested part, simultaneously because gravity, vertically disposed bearing is fitted closely with tested part end face, realize dress
The positioning set；Whole process is controlled by nut, and guarantees that the device of the invention can be around the inner circular of tested part by bearing
The telescopic rod is two-part, and tension spring is arranged between two sections.
The invention has the advantages that this device breaches turbine disc assemblies listrium end caused by blade difference in assembling process
Influence of the bounce to positioning measurement between face, realizes fast and stable measurement, and can multistage turbine disk component it is general.This structure is new
Grain husk, using reliable, scene feedback application is good, and measurement accuracy meets technique requirement, and substantially increases the measurement effect of part
Rate, measurement result can reflect the actual position of part, facilitate the control to product quality.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is location structure schematic diagram；
Fig. 4 is in working condition schematic diagram；
The present invention is illustrated with reference to the accompanying drawing, and as Figure 1-Figure 4, the present invention includes main body 10, telescopic rod 2, spiral shell
Mother 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, guide groove is set in support arm 101, and three identical telescopic rods 2 are mounted in three guide grooves 101, are fixed, stretched by cover board 11
Tension spring 31 is housed in contracting bar 2, is sprung back after realizing measurement.1 upper end of cone is external screw thread, after the through-hole of 10 center of main body
It is connect with nut 3, rotating nuts 3 realize that cone moves up and down.Cone 1 is fitted closely with three telescopic rods 2 by tension spring, cone
Body 1 moves up, and telescopic rod 2 is displaced outwardly.The bearing of 2 right-angled intersections is installed on the outside of every telescopic rod 2 by two screws
5.Telescopic rod 2 is displaced outwardly, and it is mobile to drive cantilever 4, bearing 5, until the bearing 5 of horizontal position is bonded with tested part, while by
In gravity, vertically disposed bearing 5 is fitted closely with tested part end face, the positioning of realization device.Whole process is controlled by nut 3
System, and guarantee that the device of the invention can be rotated around the internal circumference of tested part by bearing 5.
Fulcrum bar component 6 and the interference fit of main body 10 connect, and are equipped with pin anti-rotation.Fulcrum bar component is by strut, clip, tangential
The components such as clamping composition exports measurement component to position to be measured, and pilot process can carry out multiple degrees of freedom adjustment.It is logical to measure table 9
Cross screw, bushing is connected with table folder 7, table folder 7 is mounted on fulcrum bar component 6.Limited block 8 can slide in table folder 7, both sides difference
Marking scribing line, to the height value for being just afterwards exactly limited block and measurement table.Fulcrum bar component 6 is adjusted, after limited block is adjacent to tested part,
The accurate location for as needing to measure locks strut 6 thereafter through screw.After this process, limited block 8 is moved to and does not interfere position
It sets and locks, rotating body 10 realizes the circumferential measurement under the blade listrium height.
