Abstract

The present invention discloses a kind of turbine disk assembling assembly blade installation site measuring device, including measurement component and positioning component;The positioning component includes main body, the main body has three support arms for being mutually 120 degree of angles, through-hole is set in the support arm, telescopic rod is set in the through-hole, one end of telescopic rod is tapered end, the tapered end is abutted with cone, and external screw thread is arranged in the cone upper end, and the external screw thread and nut cooperate;The bearing of 2 right-angled intersections is arranged with cantilever, the end of the cantilever is fixed in the other end of the telescopic rod;The measurement component includes the strut being fixed in main body, and table folder is also set up on the strut, limited block is arranged in table folder;The end point of strut is arranged in measurement table.The invention has the advantages that this device breaches the influence that turbine disc assemblies are beated between the listrium end face caused by blade difference in assembling process to positioning measurement, fast and stable measurement is realized.

Description

A kind of turbine disk assembling assembly blade installation site measuring device
Technical field
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.
Background technique
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 Zhou Xuanzhuan;
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;
Specific embodiment
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.
