Embodiment Construction

[0035] In order to illustrate the embodiments of the present application or the technical solutions in the prior art more clearly, the embodiments will be briefly introduced below.

[0036] Such as figure 1 , the aircraft landing gear bracket workpiece 200 has a total of three through holes 201 at the front and rear and a plate body in the middle, which is triangular as a whole;

[0037] Such as Figure 2~5, a high-efficiency and high-precision fixture 100 for an aircraft landing gear bracket, used for clamping an aircraft landing gear bracket workpiece 200, including a clamp base plate 1, a fixing component 2, a pressing component 3, and an auxiliary positioning member 4. The clamp base plate 1 is from the previous It includes a front part 11, a neck 12 and a rear part 13 which is wider than the front part 11; the neck 12 is narrowed and then expanded from front to back, and the expanded part of the neck 12 is convex Part 120;

[0038] The fixed assembly 2 includes a dovet...

Abstract

The invention discloses a high-efficiency and high-precision fixture of an aircraft undercarriage bracket. The fixture comprises a fixture base plate, a fixing module, a pressing module and an auxiliary positioning piece; the fixture base plate comprises a front part, a neck part and a back part; the fixing module comprises a dovetail base, a dovetail positioning block, a positioning shaft, a positioning plate, an expansion mandrel, an expansion block, an expansion bolt and an endless bolt; the positioning plate is fixed at the back part; the expansion block and the expansion bolt respectivelycooperate with the external and the internal of the expansion mandrel; the pressing module comprises a front pressing module, a middle pressing module and a back pressing module for respectively pressing the front, middle and back parts of workpieces; and the auxiliary positioning piece comprises a movable steel ball positioning screw rod capable of adjusting the height and positioned below the workpieces, a positioning support column and a front movable screw rod. Through ordered cooperation of the fixing module, the pressing module and the auxiliary positioning piece, the clamping operationis clear, the errors are greatly reduced, and the positioning clamping precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the field of mechanical clamps, and in particular relates to a high-efficiency and high-precision clamp for aircraft landing gear brackets and a clamping method thereof. Background technique [0002] The aircraft landing gear bracket is an important part of the aircraft landing gear, usually the upper anti-twist bracket and the lower anti-twist bracket are used together. The upper end of the upper anti-twist bracket is hinged with the outer cylinder of the shock-absorbing strut, the upper end of the lower anti-twist bracket is hinged with the inner cylinder of the shock-absorbing strut, and the upper and lower anti-twist brackets are also hinged together. The three hinge axes are parallel and perpendicular to the shock-absorbing strut, so that the inner cylinder and the outer cylinder of the shock-absorbing strut can move telescopically, but cannot rotate relative to each other. Because the function of the anti-twist bracket i...
