Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a feeding mechanism for machining the outer diameter of a turbine disk. Background Technology

[0002] An aero-engine is a highly complex and precise thermodynamic machine that provides the power required for aircraft flight, directly affecting the aircraft's performance, reliability, and economy. Today, the development of aero-engines has moved from the era of piston engines to the era of turbine engines, resulting in a variety of engine categories.

[0003] The feed mechanism for machining the outer diameter of the turbine disk is a key device in the turbine disk manufacturing process. It is mainly responsible for precisely controlling the feed motion of the tool when machining the outer diameter of the turbine disk to achieve high-precision machining of the outer diameter of the turbine disk.

[0004] A prior art patent with publication number CN116442050B discloses a solution that includes machining an outer casing and an inner cylinder. The outer casing is equipped with a telescopic flipping clamping mechanism, and the outer casing contains a telescopic trimming mechanism and a chip flushing mechanism. The flipping clamping mechanism includes a horizontally arranged square support plate with a laterally rotating flipping plate on it. A circular rotating connecting plate is rotatably mounted below the flipping plate. The flipping clamping mechanism also includes a telescopically arranged first clamping frame and a second clamping frame, which are telescopically mounted on the rotating connecting plate. Several limiting posts are fixedly connected to the first and second clamping frames. This solution solves the problems of low machining accuracy and efficiency, inconvenient turbine disk clamping, interference between tool feed and turbine disk movement, and difficulty in cleaning machining chips in traditional deburring and trimming processes for turbine disks.

[0005] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0006] First, the existing turbine disk outer circle cannot adjust the angle between the turbine disk and the tool according to the machining needs during machining, which affects the machining accuracy of the turbine disk outer circle.

[0007] Secondly, existing tools used for machining the outer diameter of turbine disks can only feed in a fixed direction during the feeding process. Due to the different manufacturing processes of turbine disks, this makes it impossible to match the machining needs of different turbine disk outer diameters.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a feed mechanism for machining the outer diameter of turbine disks. This mechanism solves the problem that in traditional technologies, the angle between the turbine disk and the cutting tool cannot be adjusted according to machining needs, thus affecting the machining accuracy of the outer diameter of the turbine disk. Furthermore, existing cutting tools for machining the outer diameter of turbine disks can only feed in a fixed direction during the feeding process, which makes it impossible to match the machining needs of different turbine disk outer diameters due to different manufacturing processes.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A turbine disk outer diameter machining feed mechanism includes a base, on which a feed seat is horizontally slidably mounted. A height adjustment electric cylinder is vertically fixed to the feed seat. An angle adjustment electric cylinder is hinged to the feed seat in a parallel manner on one side of the height adjustment electric cylinder. The upper ends of the height adjustment electric cylinder and the angle adjustment electric cylinder are hinged to a support platform. A drive column is vertically rotatably mounted on the support platform. A turbine disk support platform is fixed to the upper end of the drive column. A turbine disk fixing platform is detachably mounted on the turbine disk support platform.

[0012] As an optimized solution, a screw is vertically fixed to the upper end of the turbine disk support platform, and a clearance hole for inserting into the screw is provided on the turbine disk fixing platform. A fixing nut is also threaded onto the screw, and the lower surface of the fixing nut abuts against the upper surface of the turbine disk fixing platform.

[0013] As an optimized solution, both the turbine disk support platform and the turbine disk fixing platform are arranged in a frustum shape, and the small diameter ends of the turbine disk support platform and the turbine disk fixing platform are arranged opposite each other.

[0014] As an optimized solution, a drive motor is fixedly connected to the lower surface of the support platform, and the output shaft of the drive motor is fixedly connected to the lower end of the drive column.

[0015] As an optimized solution, a bracket covering the drive motor is fixedly connected to the lower surface of the support platform, and the upper end of the height adjustment electric cylinder is hinged to the lower end of the bracket.

[0016] As an optimized solution, a lead screw is horizontally rotatably mounted on the base, and a drive seat that is threadedly connected to the lead screw is fixed to the lower surface of the feed seat.

[0017] As an optimized solution, two end seats are fixedly connected in parallel on the base, and the two ends of the lead screw are rotatably mounted on the two end seats.

[0018] As an optimized solution, one of the end seats is fixedly connected to a drive motor that drives the lead screw to rotate.

[0019] As an optimized solution, the lower surface of the feed seat is fixedly connected to a guide rail along the sliding direction of each end seat, and the guide rail is slidably supported on the end seat.

[0020] As an optimized solution, the guide rail has a T-shaped cross-section, and the upper end of the end seat has a guide groove that matches the guide rail.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The device is fixed by the base, and the lead screw is driven by the drive motor to rotate, which can realize the feeding of the feed seat and adjust the distance between it and the tool.

[0023] By setting up height adjustment electric cylinders and angle adjustment electric cylinders, when it is necessary to adjust the support height of the turbine disk, the height adjustment electric cylinders and angle adjustment electric cylinders extend and retract synchronously to achieve height adjustment of the support platform;

[0024] When the support angle of the turbine disk needs to be adjusted, the angle adjustment electric cylinder extends and retracts to adjust the tilt angle of the support platform.

[0025] By setting up a turbine disk support platform and a turbine disk fixing platform, both of which are frustoconical in shape, the turbine disk is supported. By tightening the fixing nut, the turbine disk is secured, making it easy to install and remove the turbine disk.

[0026] By driving the drive column to rotate through the drive motor, the circumferential direction of the turbine disk can be adjusted, enabling flexible feed adjustment of the turbine disk, improving the compatibility with the cutting tool, and meeting the machining needs of different turbine disk outer diameters.
