Technical Field

[0001] The invention relates to the field of aircraft traction, and in particular to a limiting device for directional installation of an air outlet joint of an air compressor. Background Art

[0002] During the assembly process of the air compressor, the gear is installed on the end face of the output shaft of the air compressor by bolts. To control the air compressor, the bolts on the gear are tightened, and the gear needs to be clamped and prevented from rotating. The existing clamp used for clamping needs to tighten the bolts on the clamp so that the clamp can clamp the gear. The operation process is slow and the assembly efficiency is low. The installation direction of the air outlet joint on the air compressor has strict restrictions to ensure connectivity with other equipment. The existing method is to use a ruler for fine-tuning after installation, which is cumbersome and has low accuracy.

[0003] The existing positioning tooling limits the gears of the air compressor by means of a plurality of sector gears. However, such a structure makes it difficult to align the gears and all the sector gears, resulting in low gear positioning efficiency. At the same time, when tightening the bolts on the gears, all the sector gears will shake, resulting in low bolt tightening efficiency. The installation direction of the air outlet joint on the air compressor is limited by only a limit rod, and the limit direction is difficult to adjust. Summary of the invention

All guide rods are sleeved with buffer springs, and both ends of the strip block are provided with positioning bolts locked with the horizontal slide.

[0007] Furthermore, the sector gear is rotatably connected to the middle section of the positioning strip via a fixing bolt, and the plane where the sector gear is located is perpendicular to the axis of the horizontal shaft.

The strip block 42 is provided with a locking bolt 45 that is locked and connected to the vertical limit rod 44. The direction limiting component 5 includes a directional portion installed on the top of the vertical square rod 51, and a positioning rod 6 for positioning the air compressor 1 is provided on the working platform 2. The air compressor 1 is placed on the working platform 2, and the gear 11 on the air compressor 1 is placed on the horizontal rack 43. The horizontal rack 43 is pressed down, and the gear 11 is manually turned to achieve the engagement of the gear 11 and the horizontal rack 43. The rotating limit strip plate drives the fan gear 33 to engage with the gear 11, thereby jamming the gear 11, and the bolt on the gear 11 can be tightened, and the air outlet joint 12 is screwed and rotated to be close to the side of the directional portion, so as to limit the installation direction of the air outlet joint 12 of the air compressor 1.

[0029] Guide rods 46 are vertically installed at both ends of the bottom of the horizontal rack 43, and a plurality of guide holes for sliding cooperation of the guide rods 46 are provided on the strip block 42. All guide rods 46 are sleeved with buffer springs 47. Both ends of the strip block 42 are provided with positioning bolts 49 that are locked and connected to the horizontal slide 41. The gear 11 on the air compressor 1 is placed on the horizontal rack 43, the horizontal rack 43 is pressed down, and the buffer spring 47 is compressed at the same time. The gear 11 is manually rotated, and the restoring force of the buffer spring 47 drives the horizontal rack 43 to rise, so that the gear 11 and the horizontal rack 43 can be meshed, and then the locking bolt 45 is tightened, and then the limiting strip plate is rotated to drive the fan gear 33 to mesh with the gear 11, so that the gear 11 of the air compressor 1 is positioned.

[0030] The sector gear 33 is rotatably connected to the middle section of the locking strip 32 via a fixing bolt 48. The plane where the sector gear 33 is located is perpendicular to the axis of the horizontal shaft 31.
