Embodiment Construction

[0024] see Figure 1 to Figure 3 , the middle part of the five-fork part A of the helicopter tail rotor is the support shaft, and five fork arms A1 are distributed on its side. The support shaft has a certain axial length, a tapered hole A4 is provided in the support shaft along the axial direction, and a keyway is machined in the tapered hole A4. Due to the unique shape and structure of the five-pronged piece A, the common slotting machine cannot clamp and position it, which brings great difficulties to the keyway processing. Based on this, combined with the structural characteristics of the five-pronged part A of the helicopter tail rotor, the present application proposes a keyway fixing and processing device for the five-pronged part of the helicopter tail rotor, including a base 1, and the base 1 is provided with a central axis for supporting and positioning the five-pronged part A. The first bushing 2 at the bottom of A2, one side of the first bushing 2 is provided with ...

Abstract

The application discloses a keyway fixing and processing device for a five-fork part of a helicopter tail rotor, which includes a base; The pressing device for pressing and fixing the five-pronged piece, the other side of the first bushing is provided with a second bushing, wherein: the first bushing is detachably provided with a tapered hole for passing through the upper of the five-pronged piece The first locating pin, the second locating pin is detachably provided on the second bushing for fixing the position of the fork on the five prongs; parts are limited. The processing device of the present application fully considers the structural characteristics of the five-pronged piece, which facilitates its positioning, tool setting and fixed processing, effectively reduces the positioning error, and improves the product qualification rate; the device is easy to use and operate, making the keyway of the five-pronged piece easy The processing is standardized and efficient.

Description

technical field [0001] The application relates to the field of mechanical processing, in particular to a keyway fixing processing device for a five-pronged piece of a helicopter tail rotor. Background technique [0002] When machining the five-pronged piece of the helicopter tail rotor, the position of the keyway at the taper hole of the five-pronged piece is strictly required. The support shaft of the five-pronged piece has five fork arms distributed in the circumferential direction, the end of each fork arm is provided with a fork, and the support shaft is provided with a tapered hole along the axial direction. Due to the unique shape and structure of the five-pronged piece, when processing the keyway at the taper hole, the ordinary slotting machine cannot accurately clamp and locate the part, and only manual adjustment by the operator results in a large positioning error, which makes the production of the parts difficult and the pass rate is relatively high. Low. SUMMA...
