Embodiment approach 1

[0051] Such as image 3 , Figure 4 As shown, in order to solve the problem that the semi-finished product of the cyclone produces large jumps and vibrations during the milling process, the present invention provides a processing tool 1 for the cyclone of an aero-engine, which can hold the cyclone when processing the semi-finished product of the cyclone. The semi-finished cyclone, the processing tool 1 includes two flywheels 11 that can be fixedly connected to the two ends of the semi-finished cyclone 100 respectively, when the semi-finished cyclone 100 is processed, the semi-finished cyclone 100 and the two ends fixed on The two flywheels 11 form an integral part and are installed on the processing machine tool. The cyclone semi-finished product 100 and the two flywheels 11 can move and rotate synchronously under the drive of the processing machine tool. For example, the processing machine tool is a CNC machine tool 2 .

[0052] The invention sets two flywheels to clamp the ...

Embodiment approach 2

[0065] Such as image 3 As shown, the present invention also provides a turning and milling equipment of an aero-engine swirler, which is used to process the semi-finished swirler 100 into a finished swirler 200. The structures of the semi-finished swirler 100 and the finished swirler 200 are as follows As mentioned above, the turning and milling equipment includes a CNC machine tool 2 and a processing tool 1. The processing tool 1 in this embodiment has the same structure, working principle and beneficial effects as the first embodiment, so it will not be described in detail here; the CNC machine tool 2 has a lathe Knife 21, milling cutter 22, and two clamping ends 23 arranged at relative intervals, and two flywheels 11 are respectively fixedly connected to the two clamping ends 23, for example, the axle sleeve 111 of the flywheel 11 is detachably fixedly connected to the clamping ends 23 , in the state that the two ends of the first shaft part 110 of the semi-finished cyclon...

Embodiment approach 3

[0077] Such as Figure 13 As shown, the present invention also provides a turning-milling method of an aero-engine swirler, which adopts the turning-milling equipment of Embodiment 2 to process the swirler semi-finished product 100 into a swirler finished product 200, and the turning-milling method of the present invention includes the following step:

[0078] Step S10: Prepare the semi-finished cyclone 100. The specific preparation method of the semi-finished cyclone 100 is the prior art, so it will not be described in detail;

[0079] Step S20: Fixing the two ends of the first shaft part 110 of the cyclone semi-finished product 100 to the two flywheels 11 respectively;

[0080] Step S30: install the integral part composed of the semi-finished cyclone 100 and the two flywheels 11 between the two clamping ends 23 of the CNC machine tool 2;

[0081] Step S40: using the milling cutter 22 of the CNC machine tool 2 to mill a swirl groove 230 on the processing part 120 of the sem...

Abstract

The invention provides a machining tool, turn-milling equipment and turn-milling method for an aero-engine hydrocyclone, the machining tool can clamp a semi-finished hydrocyclone when the semi-finished hydrocyclone is machined, the machining tool comprises two flywheels which can be fixedly connected with the two ends of the semi-finished hydrocyclone correspondingly, and when the semi-finished hydrocyclone is machined, the two flywheels can clamp the semi-finished hydrocyclone. And the cyclone semi-finished product and the two flywheels fixed at the two ends of the cyclone semi-finished product form an integral piece which is arranged on a processing machine tool. The turn-milling equipment comprises a numerical control machine tool and a machining tool. The semi-finished cyclone and the flywheel are fixedly connected into a whole, then the semi-finished cyclone is machined, the problem that the semi-finished cyclone jumps and vibrates greatly during milling due to the fact that the weight of the semi-finished cyclone is too light can be effectively solved, jumping and vibration of the semi-finished cyclone during milling are effectively reduced, the milling quality is improved, and the machining efficiency is improved. And the service life of the cutter of the turn-milling equipment is prolonged.

Description

technical field [0001] The invention relates to the field of production of aero-engine components, in particular to a processing tool for an aero-engine cyclone, turning and milling equipment and a turning and milling method. Background technique [0002] The swirler is one of the very important parts in the engine. Its function is to form the recirculation zone at the head of the flame tube, reduce the airflow velocity, form a stable fire source at the head of the flame tube, and ensure the stable operation of the combustion chamber. It is often used in aero-engines The blade swirler in the annular combustion chamber generally includes a cylinder and a number of blades spirally arranged on the cylinder, and swirl grooves are formed between two adjacent blades. Since the surface of the swirler blades is mostly complex, With different curvatures, it is difficult to cut directly. [0003] The Chinese patent with the application number CN201810290607.6 discloses a process for ...
