Abstract
The invention relates to an adjusting mechanism of an air belt rotating tester of an aircraft engine, which comprises a main supporting frame, a sliding block, a pull rod, a locking cylinder and two slide wedges. An air supply gun head is arranged on the main supporting frame; threads with different rotation directions are arranged in two hinge lugs; the pull rod is installed between the two hinge lugs in a matching way; the pull rod is installed on a piston of the locking cylinder; the pull rod is connected with the hinged lugs through the threads; the hinge lugs are hinged with a supporting arm arranged on a shaft sleeve of the air supply gun head; the two slide wedges are positioned at the bottom of the main supporting frame at two ends along the motion direction of the sliding block; and inclined planes matched with the two slide wedges are arranged below the main supporting frame. The adjusting mechanism can realize positions and rotation angles in all positions of the air supply gun head through the pull rod, the hinge lugs and the slide wedges, achieves the purpose that air belt rotating testing of the aircraft engine can be continuously performed, and has good effect after practical application.
Description
Technical field
The present invention relates to a kind of aeromotor air band and turn the exerciser adjusting mechanism.
Background technology
Aeromotor will be carried out a series of ground experiment before being delivered for use, meet the flight requirement to guarantee product.In process of the test, need to start aeromotor, so that the parameter when gathering various work.Some aeromotor start mode at work is the pyrotechnics starting, belongs to disposable start mode.Although adopt the pyrotechnics start mode can carry out ground experiment, can greatly increase production cost, when wasting financial resources, also increased the security of test run.Generally speaking, can adopt the starting of air rotary support, namely introduce pressure-air to the position of engine start blade, blow blade and then drive engine start.Behind engine work, whole band turns starting device and will break away from engine; When treating to start, whole band turns starting device and is connected, ventilates with engine next time.Although this structure is simple, can realize re-lighting, save cost, safe, but engine is after the ride fixed installation, the position of starting simulator is also just relatively fixed and can not be adjusted, and therefore needs a kind of adjusting gear, adjusts the position of main bearing support and realizes sending air gun head to enter smoothly and deviate from the coupling arrangement of engine; Adjustment send the angle position of air gun head with the locking of realization with the coupling arrangement of engine.Because the development of air rotary support is in the starting stage, therefore for position adjusting mechanism, there is not in addition reference of proven technique yet.
Summary of the invention
The purpose of this invention is to provide a kind of aeromotor air band and turn the exerciser adjusting mechanism, with the position of realizing main bearing support and the adjustment of sending the angle of air gun head, to guarantee that can carry out continuously aeromotor air band turns test.
Concrete technical scheme of the present invention is: aeromotor air band turns the exerciser adjusting mechanism and comprises main bearing support, the slide block that is connected with the piston of feeding cylinder and can slides at guide rod, by cutting with scissors the hinged pull bar of ear and main bearing support and slide block, be hingedly mounted on the locking cylinder on the main bearing support, place two wedges below the main bearing support, be provided with on the main bearing support and send air gun head, be provided with the opposite screw thread of sense of rotation in described two hinge ears, the pull bar cooperation is installed between two hinge ears, on the piston of described locking cylinder pull bar is installed, described pull bar is connected with the hinge ear by screw thread, cut with scissors ear and send the support arm that arranges on the axle sleeve of air gun head hinged, the position of described two wedges is at the two ends of main bearing support bottom along the slide block movement direction, be provided with the inclined-plane that matches with two wedges below the main bearing support, be provided with the groove identical with the slide block movement direction on the described wedge, the gib screw of main bearing support and test bay passes described groove, also be provided with the adjustment bolt identical with the groove direction on the described wedge, described adjustment bolt passes the through hole that arranges on the test bay and nut is installed, and is provided with scale on the described wedge.
The present invention is by adjusting the pull bar between main bearing support and the slide block, can make the length of pull bar relatively elongated or shorten, and then drives main supporting and swing, and reaches the position, the left and right sides of adjusting after main supporting is risen; By the position of adjustment wedge, and then the position of the lifting of the main supporting of drive; Adjust the hinge ear hinged with sending the support arm that arranges on the axle sleeve of air gun head, can adjust the rifle head-turned angle of supplying gas.
The advantageous effect that the present invention has is, by the setting of pull bar, hinge ear and wedge, can realize sending position and the anglec of rotation of all directions of air gun head, reached and guarantee to carry out continuously the purpose that aeromotor air band turns test, by the application of reality, respond well.
