Description
Technical Field
The invention relates to the field of aviation grinding machining, in particular to an open groove cutter type cutting tool for grinding a fiber inner diameter shaft sleeve.
Background
The flaperon is an important control surface installed at the trailing edge of the wing, plays a role in changing the flying attitude when the airplane takes off, lands and flies, and is an indispensable main component of a modern airplane. The flaperon is connected with the rear wall of the wing through hole-shaft matching.
In order to ensure the motion accuracy of the flaperon, the requirement on the precision of the fit clearance of the hole shaft of the flaperon pull rod is high, but the flaperon is worn through the hole shaft of the swing pull rod in flight, and the flaperon shakes to influence the performance of the airplane when the clearance is too large. In order to improve the wear resistance of the flaperon hole shaft, a shaft sleeve with better wear resistance and wear resistance fibers adhered to the inner wall is adopted as a hole shaft friction pair. The shaft sleeve with the fiber inner wall is connected with the hole of the joint fork lug in a press fit mode in an interference fit mode, but after the shaft sleeve in the interference fit mode is pressed with the connecting rod joint lug in an assembling process, the inner diameter of the shaft sleeve can change due to the size of an extrusion effect, and under the conditions of the existing processing precision and the press fit means, the inner diameter of the shaft sleeve cannot completely meet the expected precision requirement, so that the hole-shaft gap is often out of tolerance. The inner wall shaft sleeve of the fiber cannot be subjected to aperture correction through reaming, so that the aperture shaft clearance value deviation is large, the abrasion state is unstable, and the flight performance of the airplane is influenced. In the prior art, the hole shaft clearance is ensured by performing high-precision processing in advance before the machine is installed, the qualified rate of shaft sleeve processing is only 10%, the cost of the shaft sleeve is greatly increased, and manpower and material resources are seriously wasted.

By using the grinding cutting tool, field workers only need to press the shaft sleeve well when the shaft sleeve is installed, and then pre-grind the shaft sleeve by using the grinding cutting tool, so that the inner diameter of the shaft sleeve and the gap of the shaft meet the technical requirements. Therefore, the processing precision of the fiber inner wall shaft sleeve is reduced, the yield of the fiber inner wall shaft sleeve is improved, the production cost of the fiber inner wall shaft sleeve is reduced, the matching precision consistency of the fiber inner wall shaft sleeve and the rotating shaft can be effectively ensured, the abrasion life cycle of the flap fly pull rod hole shaft friction pair is prolonged, and the matching quality of the flap fly pull rod hole shaft friction pair is improved particularly under the working condition of an outfield environment.
