Description

Technical Field

[0001] The present invention relates to the technical field of torque measurement tooling, and in particular to a turboshaft engine starting torque measurement tooling system and method. Background Art

[0002] The torque measurement fixture is a device used to measure the starting torque of a turboshaft engine. When using the torque measurement fixture, the engine body is fixed by the upper front cover of the bearing seat. Before the test, the nut is manually tightened with a wrench and the screw is screwed in and out to adjust the tension, so that the readings on the two force sensors are consistent. The torque M is calculated as follows: M=F*d, where F is the tension applied to a single force sensor and d is the diameter of the torsion disk. As the applied tension and torque gradually increase, the axial force measured by the force ring also gradually increases, resulting in a "torque-axial force" calibration relationship.

[0003] The inventor found in his daily work that the torque measuring tool still has at least the following problems: when using the torque measuring tool, the engine body is fixed by the upper front cover of the bearing seat. Before the test, the nut is manually tightened with a wrench and the screw is screwed in and out to adjust the tension, so that the readings on the two force sensors are consistent. The calculation method of the torque M is: M=F*d, where F is the tension exerted on a single force sensor, and d is the diameter of the torsion disk. The applied tension and torque gradually increase, and the axial force measured by the force ring also gradually increases, obtaining a "torque-axial force" calibration relationship. However, in actual use, after the test is completed, in order to ensure the accuracy of the test, it is necessary to adjust the value of the force sensor for re-measurement, which requires manual use of a wrench to turn the nut multiple times, which is more troublesome.

The first connecting belt 806 is sleeved on the surface of the second pulley 809. When using the rotating device 8, the round rod 808 is manually controlled to rotate to perform The first pulley 805 is driven to rotate by the first connecting belt 806. Because the blocking block 804 is well stuck in the surface of the nut 15, the first pulley 805 can well drive the nut 15 to rotate, and can simultaneously control the two screws 14 to be screwed out or screwed in, so that the two screws 14 can be adjusted to be screwed out or screwed in the torque transmission support plate 16 at the same time. In this way, data can be changed to perform measurements of different degrees, ensuring the accuracy of the measurement, and thus avoiding multiple operations to a certain extent. Rotation grooves 802 are provided on both sides of the torque transmission support plate 16, and a rotating ring 803 is rotatably sleeved on the inner wall of the rotating groove 802.

When using the connecting device 9, manually slide the fixing block 902 into the inside of the fixing groove 901, and then put the semicircular plate 905 on the surface of the supporting sleeve 10, so that the positioning plate 904 passes through one side of the fixing groove 901 and is inserted into the inside of the positioning groove 903. In this way, the fixing block 902 can be fixed to the inside of the fixing groove 901. The surface of the supporting sleeve 10 is fixedly connected with a supporting ring 909. The support ring 909 is provided with a positioning groove 910 at one end close to the supporting sleeve 10. The inner wall of the positioning groove 910 is slidably connected to the limiting ring 907, and the limiting ring 907 is slidably sleeved on the surface of the semicircular plate 905. The limiting ring 907 is manually controlled to slide out of the positioning groove 910, so that the limiting ring 907 is slidably sleeved on the surface of the semicircular plate 905, so that the semicircular plate 905 can be restricted to the surface of the supporting sleeve 10 by the limiting ring 907. A rectangular groove 908 is provided on the surface of the limiting ring 907, and a rubber block 906 is provided on the inner wall of the rectangular groove 908.

[0036] Working principle: When using the torque measuring tool, fix the engine body through the upper front cover 5 of the bearing seat 7. Before the test, manually tighten the nut 15 with a wrench and control the screw 14 to screw in and out to adjust the tension, so that the readings on the two force sensors 13 are consistent. The calculation method of the torque M is: M=F*d, where F is the tension exerted on a single force sensor 13, and d is the diameter of the torsion disk 11. The applied tension and torque gradually increase, and the axial force measured by the force ring 6 also gradually increases, and the "torque-axial force" calibration relationship is obtained. When using the rotating device 8, manually control the rotation of the handle 811. The second connecting belt 813 can well drive the round rod 808 to rotate through the handle 811, and then through the first connecting belt The belt 806 drives the first pulley 805 to rotate. Because the blocking block 804 is well stuck on the surface of the nut 15, and the rotating ring 803 is rotatably arranged inside the rotating groove 802, the blocking block 804 can be well restricted to one side of the torque transmission support plate 16, and then the first pulley 805 can well drive the nut 15 to rotate, and then can simultaneously control the two screws 14 to be screwed out or screwed in, so that the two screws 14 can be adjusted to be screwed out or screwed into the torque transmission support plate 16 at the same time, so that the data can be changed to perform different degrees of measurement, ensuring the accuracy of the measurement, and thus avoiding multiple operations to a certain extent. When the handle 811 drives the round rod 808 to rotate to the appropriate position, the rubber ring 820 is manually set to the shift The top of the movable rod 819 is driven by the movable rod 819, and the locking bar 816 is driven to slide to the top of the gear 814 through the movable rod 819, and then the locking bar 816 is pulled to the bottom of the sliding groove 815 by the first spring 818, so that the gear 814 can be well stuck. When the handle 811 needs to be rotated, the locking bar 816 is manually driven away from the gear 814 by the movable rod 819, and then the rubber ring 820 is manually set at the bottom of the movable rod 819, so that the locking bar 816 can be kept away from the gear 814, thereby preventing the locking bar 816 from affecting the rotation of the handle 811. When using the connecting device 9, the fixing block 902 is manually slid into the inside of the fixing groove 901, and then the semicircular plate 905 is sleeved on the surface of the supporting sleeve 10, so that After the locking plate 904 passes through one side of the fixing groove 901, it is inserted into the inside of the locking groove 903, so that the fixing block 902 can be fixed inside the fixing groove 901, and then the limiting ring 907 is manually controlled to slide out of the positioning groove 910, so that the limiting ring 907 is slidably sleeved on the surface of the semicircular plate 905, and then the rubber block 906 is squeezed into the inside of the rectangular groove 908, so that the limiting ring 907 can be set on the surface of the semicircular plate 905, so that the semicircular plate 905 can be restricted to the surface of the supporting sleeve 10 by the limiting ring 907, and is moved away from the positioning by the second spring 912. The reverse operation can be used to remove the torsion disk 11, and then different models of torsion disks 11 can be replaced. The calculation method of torque M is: M=F*d,Where F is the tensile force on a single force sensor 13, and d is the diameter of the torsion disk 11. The diameter can be changed to adjust the amplitude of M.

[0037] It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction and extension process.
