Description

Technical Field

[0001] The invention belongs to the technical field of aircraft engine parts processing tooling, and in particular relates to an aircraft engine agile tooling debugging device. Background Art

[0002] In the manufacturing and processing of aircraft engine parts, more and more agile tooling has appeared. Agile tooling usually includes cylinders, oil cylinders, zero-point positioning systems, servo motors, etc., and is equipped with air sources and hydraulic stations to provide power for tooling operations.

[0003] The traditional approach is to provide power directly to the air cylinders, oil cylinders and other actuators in the tooling through air sources and hydraulic stations. However, this power supply method has obvious problems. Specifically, the clamping force generated by the tooling cannot be directly observed and needs to be calculated through the pressure of the air control system, hydraulic system and the cylinder diameter of the cylinder.

[0004] However, since traditional methods lack the ability to stably adjust the pressure system and test the clamping force, for the manufacturing and processing of aircraft engine parts, especially thin-walled parts, due to their complex processing technology, they are very easy to deform during processing. Once the agile tooling fails to achieve stable output of clamping force, it may cause problems in part processing. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides an agile tooling debugging equipment for aircraft engines, which integrates pneumatic, hydraulic, servo control and other functions, and forms an "edge computing" platform integrating comprehensive computing, storage, and application. It effectively improves the debugging efficiency of agile tooling, shortens the mold change time during the processing of aircraft engine parts, can directly control and observe the clamping force of the agile tooling, and establish a clamping force database of the agile tooling. It can provide necessary parameters for physical simulation and manufacturing deformation control of aircraft engines, and can provide accurate analysis basis for aircraft engine processing quality analysis based on big data.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an agile tooling debugging equipment for an aircraft engine, comprising a control cabinet body, an electrical panel and a control panel; the electrical panel is vertically installed inside the control cabinet body; the control panel is obliquely installed on the top of the control cabinet body; an industrial computer and an HMI are arranged in parallel on the control panel, both of which are equipped with display screens, and function buttons used in conjunction with the industrial computer and the HMI are also arranged on the control panel; a PLC, an intermediate relay, a switching power supply, an AC contactor, an air switch, a servo controller and a wiring trough are respectively arranged on the front surface of the electrical panel, and a hydraulic proportional valve group and a pneumatic switch valve are respectively arranged on the rear surface of the electrical panel; a hydraulic station is arranged on the bottom side of the control cabinet body; a hydraulic pipe is arranged on the left side of the outside of the control cabinet body, and a quick connector is arranged at the pipe mouth of the hydraulic pipe; a first aviation socket, a second aviation socket, a third aviation socket, a first air pipe joint and a second air pipe joint are respectively arranged on the right side of the outside of the control cabinet body; the first aviation socket is externally connected to a pressure sensor.

[0007] The control cabinet body adopts a front and rear double-door structure, the control panel adopts an upward flip structure, a keyboard drawer is arranged inside the control cabinet body below the control panel, and a self-locking universal wheel is arranged at the bottom of the control cabinet body.

[0008] The first air pipe joint is used to connect to an external air source, and the external air source is connected to the air inlet port of the air pressure switch valve through the first air pipe joint. The air outlet port of the air pressure switch valve is connected to the second air pipe joint, and the second air pipe joint is used to provide pneumatic power to the cylinder in the agile tooling.

[0009] The hydraulic station is connected to the hydraulic pipe through a hydraulic proportional valve group. The hydraulic pipe is used to provide pressure oil to the hydraulic cylinder in the agile tooling; the hydraulic pipe is a metal hose.

[0010] The servo controller is used to realize single-axis servo control, and the servo controller is electrically connected to the servo motor in the hydraulic station through the second aviation socket or the third aviation socket.

The host computer human-machine interface is displayed through the display screens of the industrial computer and the HMI. The pneumatic clamping and loosening or hydraulic clamping and loosening of the agile tooling are controlled through the host computer human-machine interface. The hydraulic system of the agile tooling is quantitatively adjusted, pressure monitored, fault alarmed, error-proof monitored, and pressure data collected through the host computer human-machine interface; the operating program of the servo motor in the hydraulic station is loaded through the HMI5 as the parameter input port for the speed and angle of the servo motor.

[0012] The pressure sensor is electrically connected to the industrial computer through the first aviation socket. The pressure sensor serves as a clamping force detection sensor for the agile tooling. The sampling signal of the pressure sensor needs to be digitally low-pass filtered to remove high-frequency noise, and the pressure value is displayed in real time on the display screen of the industrial computer.

[0035] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:

[0036] Take the debugging of agile tooling that uses a cylinder as the clamping force output actuator as an example.

[0037] First, the debugging device of the present invention is moved to the area where the agile tooling to be debugged is located, and then the external air source is connected to the first air pipe joint 22 through the air pipe, and then the air pipe is used to connect the cylinder in the agile tooling to the second air pipe joint 23.

[0038] Power on and enable the debugging device of the present invention to enter the startup state, connect the data line of the pressure sensor 24 to the debugging device of the present invention through the first aviation socket 19, then perform a press test on the pressure sensor 24, and observe whether the pressure value is normally displayed on the display screen of the industrial computer 4. After the detection is normal, clamp the standard test piece for debugging into the agile tooling, and install the pressure sensor 24 between the test piece and the tooling clamp block. Then, the industrial computer 4 and HMI5 perform logical control on PLC7, and PLC7 further performs logical control on the cylinder in the agile tooling by controlling the air pressure switch valve 15, and then realizes the clamping of the standard test piece by controlling the cylinder action. During the clamping process, the clamping force can be observed in real time through the display screen of the industrial computer 4, and pressure data is collected and a clamping force database is established at the same time until the debugging of the agile tooling is completed.

[0039] Take the debugging of agile tooling that uses a hydraulic cylinder as the clamping force output actuator as an example.

[0040] First, move the debugging device of the present invention to the area where the agile tooling to be debugged is located, power on and turn on the debugging device of the present invention, connect the data line of the pressure sensor 24 to the debugging device of the present invention through the first aviation socket 19, then perform a press test on the pressure sensor 24, and observe whether the pressure value is normally displayed on the display screen of the industrial computer 4.
