Description

Technical Field

[0001] The present invention relates to the field of tooling fixtures, and particularly to a three - coordinate rapid measurement device for an aviation single blade based on a positioning tooling. Background Technique

[0002] At present, for the three - coordinate measurement method of conventional aviation single blades, first, a vise is used to fix the blade, then the three - coordinate program is run, and in the manual mode, the measuring operator touches 6 pre - calibrated positioning points on the blade to establish a rough coordinate system. After the rough coordinate system is established, the three - coordinate system switches to the automatic mode to perform 6 - point iteration to establish an accurate coordinate system. After the coordinate system is established, various parameters of the blade are measured. The subsequent fixing work before blade measurement causes the three - coordinate measuring instrument not to operate continuously, reducing the machine usage efficiency. Summary of the Invention

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1-9, A three - coordinate rapid measurement device for a single - blade of an aircraft based on a positioning tooling shown in the figure, includes: a rotating table 1 and six positioning frame plates 3 fixedly installed on the upper end surface of the rotating table 1. A first rotating shaft 2 is fixedly arranged at the center of the rotating table 1, and a motor for driving is also arranged at the bottom of the first rotating shaft 2. The position of the motor is relatively fixed with respect to the position of the rotating table 1. The motor drives the rotating table 1 to rotate through the first rotating shaft 2. The six positioning frame plates 3 are circumferentially and equally spaced around the first rotating shaft 2. A positioning groove 7 is formed on the upper end surface of each positioning frame plate 3, and the positioning groove 7 is used for placing a single - blade workpiece;

[0030] A clamping unit, used for effectively clamping and positioning the single - blade workpiece in the positioning groove 7. The clamping unit is arranged between each positioning frame plate 3 and the rotating table 1;

[0031] A bottom - positioning unit, which makes the bottom surface of the single - blade workpiece closely adhere to the upper end surface of the positioning groove 7. The bottom - positioning unit is arranged inside the clamping unit.

[0032] The clamping unit includes two hollow sliding plates 4 slidably inserted inside each positioning frame plate 3. The two hollow sliding plates 4 are symmetrically distributed with the positioning groove 7 as the symmetry center. A clamping plate 6 is fixedly sleeved on the outer surface of one end of each hollow sliding plate 4 extending into the positioning groove 7. Rubber pads are fixedly arranged on the facing end faces of the two clamping plates 6. A L - shaped frame 5 is fixedly arranged at the bottom of each hollow sliding plate 4. A first gear 13 is placed at the bottom of the rotating table 1. The first gear 13 is located directly below the positioning groove 7. The two L - shaped frames 5 are circumferentially and equally spaced around the first gear 13. A number of tooth blocks 8 are fixedly arranged on the end face of each L - shaped frame 5 close to the first gear 13 at equal intervals in a straight line, and the first gear 13 is meshed with the number of tooth blocks 8. A limit frame 9 is fixedly arranged at the bottom of the rotating table 1. The limit frame 9 is slidably buckled outside the two L - shaped frames 5 and a first gear 13. A rotating column 11 fixedly embedded inside the first gear 13 is rotatably arranged inside the limit frame 9, and a turntable 12 is fixedly sleeved on the other end of the rotating column 11. A limiting component is also arranged on the outer surface of the rotating column 11. By rotating the turntable 12 to rotate the rotating column 11, under the meshing of the first gear 13 and the tooth blocks 8, the two L - shaped frames 5 are made to drive the hollow sliding plates 4 to move synchronously and in opposite directions, so that the two clamping plates 6 can clamp or release the single - blade workpiece in the positioning groove 7.

[0033] The limiting component includes a sleeve 10 rotatably sleeved on the outer surface of the rotating column 11, and the sleeve 10 is fixedly assembled with the limiting frame 9. A hollow cylinder 23 is also fixedly communicated with the outer wall of the sleeve 10, and the axis of the hollow cylinder 23 is perpendicular to the axis of the sleeve 10. A plurality of ratchet grooves 27 are arranged on the outer wall of the rotating column 11 at equal circumferential intervals. A second sliding disc 29 is slidably assembled inside the hollow cylinder 23. A column is fixedly arranged inside the second sliding disc 29, and a limiting ratchet block 28 is fixedly arranged at one end of the column close to the rotating column 11. The limiting ratchet block 28 is movably engaged with the ratchet groove 27. A dial block is fixedly arranged at the end of the column far from the rotating column 11. A second spring 30 is arranged between the end of the second sliding disc 29 far from the rotating column 11 and the hollow cylinder 23, and the second spring 30 is sleeved outside the column. Through the restriction of the ratchet groove 27 by the limiting ratchet block 28, the rotating column 11 can only rotate unidirectionally inside the sleeve 10. When rotating, the two L-shaped frames 5 are moved closer to each other, and the two clamping plates 6 clamp the single-blade workpiece.

[0034] A buffer component is also arranged between each L-shaped frame 5 and the rotating table 1. The buffer component includes a connecting rod 34 fixed at one end of each L-shaped frame 5 close to the rotating table 1. A magnetic column 32 is fixedly arranged at the exposed end of the connecting rod 34. A copper tube 31 is slidably sleeved on the outer surface of the magnetic column 32, and the copper tube 31 is fixed inside the rotating table 1. A third spring 33 is also fixedly arranged between the L-shaped frame 5 and the rotating table 1, and the third spring 33 is distributed outside the connecting rod 34. When the magnetic column 32 moves inside the copper tube 31, it will be affected by electromagnetic damping. When the compressed third spring 33 pushes the L-shaped frame 5 away and the magnetic column 32 moves out of the copper tube 31, the moving speed of the L-shaped frame 5 will be slowed down.

[0035] The limiting ratchet block 28 is in the shape of a right trapezoid, and the inclined surface of the limiting ratchet block 28 is in sliding contact with the inclined surface of the ratchet groove 27.

[0036] The dial block is located outside the hollow cylinder 23, and the dial block is convenient for the staff to pull the column.

[0037] Example two: Please refer to Figures 3-6, This embodiment is a further illustration of the above embodiment. The bottom positioning unit includes a cavity opened inside each hollow slide plate 4. One end of the cavity close to the positioning groove 7 is open. A shelf plate 14 is placed inside each cavity. Two second rotating shafts 15 are rotatably arranged inside the shelf plate 14. A second gear 16 is fixedly sleeved on the outer surface of each second rotating shaft 15. A synchronous toothed belt 17 is commonly driven and assembled on the outer surfaces of the two second rotating shafts 15 on the same side. A plurality of equally spaced ribs 18 are fixedly arranged on the outer surface of the synchronous toothed belt 17. One end of the synchronous toothed belt 17 extends into the positioning groove 7. An elastic support member is arranged at the end of the shelf plate 14 away from the positioning groove 7. A rotating member is also arranged between the shelf plate 14 and the hollow slide plate 4. The elastic support member is used to support the shelf plate 14 and the synchronous toothed belt 17 inside the cavity. Moreover, the shelf plate 14 and the cavity are parallelly distributed. The rotating member can deflect the synchronous toothed belt 17 when the shelf plate 14 is displaced.

[0038] The elastic support member includes a slide rod 19 fixed at the end of the shelf plate 14 away from the positioning groove 7. The other end of the slide rod 19 is fixedly provided with a first sliding disk 20. The outer surface of the first sliding disk 20 is slidably sleeved with a limit cylinder 21. The limit cylinder 21 is fixed inside the cavity. A first spring 22 is fixedly arranged between the end of the first sliding disk 20 away from the shelf plate 14 and the limit cylinder 21. When the two shelf plates 14 move towards each other to clamp the single-blade workpiece through the synchronous toothed belt 17, the first sliding disk 20 compresses the first spring 22, so that the rubber cushion block on the surface of the clamping plate 6 clamps the single-blade workpiece.

[0039] The rotating member includes a straight groove 26 opened outside the hollow slide plate 4. The straight groove 26 is communicated with the cavity. The end of one of the second rotating shafts 15 is slidably inserted into the straight groove 26. A third gear 24 is fixedly sleeved on the end of the second rotating shaft 15 extending out of the straight groove 26. A rack 25 is fixedly arranged on the outer wall of the hollow slide plate 4. The rack 25 is movably engaged with the third gear 24. When the shelf plate 14 moves, through the engagement of the third gear 24 and the rack 25, the second rotating shaft 15 can deflect the synchronous toothed belt 17 through the second gear 16.

[0040] The rib 18 is made of silicone rubber material. When the silicone rubber textured rib 18 contacts the single-blade workpiece, it can generate a large frictional force.

[0041] Working principle: The staff sequentially fix multiple single-blade workpieces inside the six positioning grooves 7, and then rotate the rotating column 11. The rotating column 11 meshes with the tooth block 8 through the first gear 13, enabling the two L-shaped frames 5 to move synchronously towards each other, causing the clamping plates 6 at the ends of the two hollow sliding plates 4 to approach each other. During the movement, the ribs 18 on the surface of the synchronous toothed belt 17 will first come into contact with the surface of the single-blade workpiece. When the synchronous toothed belt 17 and the ribs 18 abut against the surface of the single-blade workpiece and cannot continue to move horizontally, and at this time the two clamping plates 6 still continue to move towards each other, the sliding rod 19 at the end of the frame plate 14 will push the first sliding disc 20 into the limiting cylinder 21, compressing the first spring 22. During the horizontal movement of the frame plate 14, since the third gear 24 meshes with the rack 25 and the rack 25 is located above the third gear 24, when the frame plate 14 drives the second rotating shaft 15 to move horizontally, it can cause the second rotating shaft 15 to drive the synchronous toothed belt 17 to deflect clockwise by a certain distance through the second gear 16. The synchronous toothed belt 17 can then press down on the clamped single-blade workpiece through the ribs 18, making the bottom of the single-blade workpiece fit tightly with the end surface inside the positioning groove 7. As the two clamping plates 6 continue to move towards each other to clamp the single-blade workpiece, the single-blade workpiece can be firmly clamped while its bottom abuts against the positioning groove 7, thereby further improving the clamping stability of the single-blade workpiece.

[0042] After clamping the six single-blade workpieces stably, driven by the motor, the rotating table 1 can be deflected at equal angles, enabling each single-blade workpiece to be measured for its appearance by the three-coordinate measuring instrument in turn. Moreover, during the measurement process, the staff can disassemble and replace the single-blade workpieces that have been measured, effectively improving the measurement efficiency of batch single-blade workpieces.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
