Problems solved by technology

However, when the existing polishing machines on the market are polishing the flap slide rail, due to the integrated structure of the polishing disc, the polishing disc and the flap slide rail are in integral contact during polishing, so it is difficult to perform multi-stage polishing on the flap slide rail. Precision polishing, so the polishing effect of the flap slide rail is poor when polishing, which leads to insufficient flatness and poor finish of the flap slide rail

Embodiment 1

[0035] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 8 As shown, the present embodiment provides a polishing machine for finishing an aircraft flap slide rail, comprising a casing 1, a workbench 2 is arranged inside the casing 1, and a frame 3 is symmetrically arranged on both sides of the top of the workbench 2, The opposite inner sides of the two racks 3 are provided with a polishing mechanism 4; any polishing mechanism 4 includes a side plate 40, an electric push rod 41 and a polishing assembly, and the side plate 40 away from the rack 3 passes through the electric push rod 41. Connected with the polishing assembly; the polishing assembly includes a polishing disc 42 and a power assembly 43 for driving the polishing disc 42 to rotate, one side of the power assembly 43 is connected to the output end of the electric push rod 41, and the power assembly 43 is far away from the electric One side of the push rod 41 is connected with the...

Embodiment 2

[0045] like Figure 7 As shown in the figure, a polishing machine for the finishing of aircraft flap slide rails further includes a polishing mechanism 422 staggered on the polishing surfaces of the first polishing sub-disk 420 and the second polishing sub-disk 421. The polishing mechanism 422 includes one end that is opposite to the polishing surface. Connected empty groove 4220, hydraulic push rod 4221 and grinding piece 4222, one end of the empty groove 4220 communicating with the polishing surface is provided with a placing groove, the grinding piece 4222 is embedded in the placing groove, and one side protrudes outside the flared part, The hydraulic push rod 4221 is coaxially arranged in the cavity 4220, and the output end is connected with the grinding piece 4222 through the piston rod, so that when the polishing machine polishes the slide rail, the hydraulic push rod 4221 can push the grinding piece 4222 to be close to the grinding piece 4222. On the to-be-polished surf...

Abstract

The invention discloses a polishing machine for finishing a flap slide rail of an aircraft, which comprises a casing, a workbench is arranged inside the casing, and two sides of the top of the workbench are symmetrically provided with frames, and the opposite inner sides of the two frames are A polishing mechanism is provided; any polishing mechanism includes a side plate, an electric push rod and a polishing assembly, and the side plate of the side plate away from the frame is connected with the polishing assembly through an electric push rod; the polishing assembly includes a polishing disc and a polishing plate for driving the polishing assembly. The power assembly for the rotation of the optical disc, one side of the power assembly is connected with the output end of the electric push rod, and the side of the power assembly away from the electric push rod is connected with the polishing disc; the polishing disc includes a first polishing sub-disk and a coaxial The second polishing sub-disk is sleeved on the middle of the outer surface of the first polishing sub-disk and has a thickness smaller than the thickness of the first polishing sub-disk; multi-stage grinding and polishing is performed on the inner groove surface of the sliding rail of the flap slide rail to ensure that the flap slides smoothly. The flatness of the inner groove surface of the slide rail of the rail, thereby improving the polishing accuracy of the aircraft flap slide rail.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing, in particular to a polishing machine for finishing a flap slide rail of an aircraft. Background technique [0002] Flaps refer to an airfoil-shaped movable device on the edge part of modern wings. The flaps can be installed on the trailing or leading edge of the wing and can be deflected downward or (and) slid backwards (forwards). The basic utility is to increase lift in flight. Flaps can be divided into trailing edge flaps and leading edge flaps according to the different installation positions and specific functions; and the movement of the flaps is mostly driven by the driving mechanism, so that it can be unfolded along the corresponding flap slide rails. Or closed, so in the aircraft, the flap slide rail is an important part that determines the flap attitude of the aircraft. Therefore, for the flap slide rail, its flatness is a crucial key indicator. Currently, the flap slide...
