Description

Technical Field

[0001] This invention relates to the field of aero-engine component assembly technology, and in particular to an automated high-temperature hot-pressing assembly system and method for aero-engine components. Background Technology

[0002] During the assembly of aero-engine components, some parts require interference fits, insertion of shafts, pressing, or tightening at high temperatures. This type of high-temperature hot-press assembly places high demands on heating temperature, removal time after heating, transfer time, and the precision of the pressing process. If the transfer and assembly processes rely on manual operation, it not only easily leads to safety risks in high-temperature operations, but also easily affects assembly quality and production efficiency due to the unstable cycle of manual operation.

[0003] In existing assembly methods, parts to be assembled are typically heated manually in a heating device until they meet assembly requirements, then manually removed and transported to the assembly station. Subsequent manual operations such as inserting shafts, pressing, tightening, or subsequent cooling are then performed. This method suffers from low automation, high labor intensity, long transfer times for high-temperature workpieces, difficulty in maintaining stable assembly cycle time, and low efficiency in connecting workstations, making it unsuitable for the large-scale, automated, and consistent assembly requirements of aerospace components.

[0004] Especially for aero-engine components such as impellers and turbines, when different parts need to be heated according to their respective process temperatures before hot-press assembly, the lack of an integrated system that can connect automatic delivery, visual positioning, rapid high-temperature loading and unloading, assembly, pressure holding and cooling, and inspection can easily lead to problems such as unstable process connections, uncontrollable temperature loss, and high risks of manual high-temperature operations.

[0005] Therefore, it is necessary to provide an automated high-temperature hot pressing assembly system and method that can integrate and schedule automatic delivery, visual positioning, robot gripping, rapid high-temperature loading and unloading, automatic heating, human-machine collaborative pressing, automatic pressure holding and cooling, and detection processes. Summary of the Invention

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2 As shown, this embodiment provides an automated high-temperature hot-press assembly system for aero-engine components, including a human-machine collaborative assisted assembly table 1, an automatic pressure-holding and cooling device 2, a high-temperature automatic heating device 3, a rapid automatic loading and unloading device 4, a robot gripping system 5, an electrical control system 6, a safety fence system 7, special tooling 8, an automatic docking system 9, an AGV automatic delivery system 10, a dynamic balancing machine 11, and a workstation control console 12. The electrical control system 6 and the workstation control console 12 together constitute an automated workstation control system, used for unified scheduling and display of the operating status of the various execution devices in this embodiment.

[0021] The automated transfer system 9 is located between the AGV automated delivery system 10 and the automated high-temperature hot pressing assembly area. The AGV automated delivery system 10 is used to automatically deliver the special tooling 8 loaded with aircraft engine components to the automated transfer system 9. The automated transfer system 9 is used to receive, temporarily store, or locate the special tooling 8 so that the robot grasping system 5 can subsequently grasp and transfer it.

[0022] like Figure 5 As shown, the special tooling 8 is used to carry or clamp aero-engine components. The special tooling 8 includes a tray 8-1, locking blocks 8-2, and screws 8-3. The tray 8-1 can be a square tray with a central groove. The screws 8-3 are respectively located on the four sides of the tray 8-1, and the locking blocks 8-2 are located inside the central groove. When the impeller 8-4 or centrifugal impeller is placed in the central groove of the tray 8-1, the operator or actuator can screw the screws 8-3 from the four sides of the tray 8-1, causing the screws 8-3 to push the corresponding locking blocks 8-2 towards the center of the central groove, thereby clamping and fixing the impeller 8-4 or centrifugal impeller. By adjusting the screw depth of the screws 8-3, the clamping force of the locking blocks 8-2 on the components can be adjusted to prevent the components from shaking during movement. The special tooling 8 may also be equipped with visual positioning features. By recognizing these visual positioning features, the robot grasping system 5 can determine the position and attitude of the special tooling 8 and the aero-engine components it carries, thereby improving the grasping and positioning accuracy.

[0023] The robot gripping system 5 may include a multi-degree-of-freedom robot, a vision camera, and a recognition fixture for mounting the vision camera. The vision camera is mounted on the recognition fixture, which is clamped in a ring-like manner at the end effector of the multi-degree-of-freedom robot's robotic arm, allowing the vision camera to move with the end effector and image and recognize the dedicated fixture 8, the part to be assembled, or the corresponding positioning features. After the visual recognition result is transmitted to the multi-degree-of-freedom robot, the robot grips the dedicated fixture 8, the shaft to be assembled, or the assembled product based on the recognition result. The robot gripping system 5 can transfer the dedicated fixture 8 containing the product from the automatic docking system 9 to the rapid automatic loading and unloading device 4, and can also grip the shaft to be assembled during the assembly process and insert it into the heated part to be assembled.

[0024] The high-temperature automatic heating device 3 is used to automatically heat the parts to be assembled. In this embodiment, different parts to be assembled may include impellers and turbines. The impellers and turbines can be fed into the high-temperature automatic heating device 3 respectively and heated according to their respective process temperatures. The high-temperature automatic heating device 3 can be configured as one set, or as two or more sets. When the high-temperature automatic heating device 3 is a single set, the impellers and turbines can be fed into the same high-temperature automatic heating device 3 in batches according to their respective process temperatures. When the high-temperature automatic heating device 3 is configured as two or more sets, the impellers and turbines can be fed into their respective high-temperature automatic heating devices 3 respectively. Under the control of the electrical control system 6, the high-temperature automatic heating device 3 can perform actions such as automatic door opening, receiving parts to be assembled, heating, completion prompts, and automatic material unloading.

[0025] like Figure 4As shown, the rapid automatic loading and unloading device 4 includes a telescopic mechanism 4-1, a rotating mechanism 4-2, a lateral movement mechanism 4-3, a lifting mechanism 4-4, and a main body mechanism 4-5. The lateral movement mechanism 4-3 and the lifting mechanism 4-4 are used to adjust the lateral and height positions of the special tooling 8 or the parts to be assembled; the rotating mechanism 4-2 is used to adjust the pick-up and put-down angles of the special tooling 8 or the parts to be assembled; the telescopic mechanism 4-1 includes a telescopic arm that can extend into or near the pick-up and put-down positions of the high-temperature automatic heating device 3, the human-machine collaborative assembly table 1, and the automatic pressure-holding and cooling device 2. The portion of the telescopic arm that extends into or near the high-temperature area of ​​the heating furnace is made of a high-temperature resistant alloy material. Through the coordinated telescopic, rotating, lateral, and lifting movements, the rapid automatic loading and unloading device 4 can quickly transfer aero-engine components under high-temperature conditions between heating, assembly, and pressure-holding / cooling stations.

[0026] like Figure 3 As shown, the human-machine collaborative auxiliary assembly table 1 includes a worktable body 1-1, a safety protection system 1-2, a limiting support mechanism 1-3, an auxiliary pressing mechanism 1-4, a tightening system 1-5, and an auxiliary support mechanism 1-6. The worktable body 1-1 carries the parts to be assembled; the safety protection system 1-2 provides safety protection for the human-machine collaborative area; the limiting support mechanism 1-3 and the auxiliary support mechanism 1-6 limit and support the heated parts to be assembled; the auxiliary pressing mechanism 1-4 presses the inserted shaft to be assembled; and the tightening system 1-5 tightens the parts requiring threaded connections. Therefore, the human-machine collaborative auxiliary assembly table 1, in conjunction with the robot gripping system 5, can achieve shaft insertion, pressing, and thread tightening under high-temperature conditions.

[0027] The automatic pressure-holding cooling device 2 is used to maintain pressure and rapidly cool the workpiece after press-fitting. A laser sensor is installed on the inner wall of the pressure-holding device 2. The laser sensor measures the workpiece surface temperature using infrared laser light to obtain the workpiece temperature status during the cooling process. The air inlet pipe of the automatic pressure-holding cooling device 2 is a flexible metal hose, which is designed to bend to adjust the outlet direction, and the outlet of the metal hose is aligned with the workpiece surface. A movable bracket is connected to the end of the metal hose, which can move vertically, horizontally, and vertically, driving the metal hose to circulate along the workpiece surface, thereby changing the blowing position and direction of the cooling airflow. Through this structure, the automatic pressure-holding cooling device 2 can direct the cooling airflow to the target area of ​​the workpiece according to the workpiece surface temperature and the required cooling area, improving cooling efficiency and the consistency of the cooling process.

[0028] The dynamic balancing machine 11 is used to perform dynamic balancing tests on the cooled products. After passing the test, the robot gripping system 5 transfers the product and places it on the dedicated tooling 8 or the docking position on the automatic docking system 9. Subsequently, the AGV automatic delivery system 10 delivers the product to the next workstation. The safety fence system 7 is set around the automatic high-temperature hot pressing assembly area to isolate and protect the robot gripping, high-temperature transfer, and pressing operation areas.

[0029] The automated workstation control system is used for unified scheduling and management of the AGV automated delivery system 10, robot gripping system 5, rapid automated loading and unloading device 4, high-temperature automated heating device 3, automated pressure holding and cooling device 2, and dynamic balancing machine 11. Operators can view assembly progress, equipment operating status, workstation production scheduling, and real-time equipment data through the workstation control console 12. The electrical control system 6 can control each piece of equipment to perform actions such as automatic door opening and closing, automatic material handling, automatic transfer, automatic pressure holding and cooling, and automatic detection according to the task instructions issued by the workstation control console 12.

[0030] The working process of this embodiment may include the following steps: The operator initiates a material requisition or assembly task through the workstation control console 12. After receiving the instruction, the AGV automatic delivery system 10 delivers the special tooling 8 loaded with aero-engine components to the automatic transfer system 9. The robot grasping system 5 identifies the special tooling 8 or the parts to be assembled through a vision camera and places the special tooling 8 or the parts to be assembled containing the products on the rapid automatic loading and unloading device 4. The rapid automatic loading and unloading device 4 transports the impeller and turbine to the high-temperature automatic heating device 3 respectively, and automatically heats them according to their respective process temperatures. After heating is completed, the rapid automatic loading and unloading device 4 removes the high-temperature parts to be assembled and places them on the human-machine collaborative assisted assembly table 1. The robot gripping system 5 grips the shaft to be assembled and inserts it into the heated part to be assembled. The auxiliary pressing mechanism 1-4 performs pressing, and the tightening system 1-5 tightens the threads according to the process requirements. After pressing, the rapid automatic loading and unloading device 4 transfers the workpiece to the automatic pressure holding and cooling device 2 for pressure holding and rapid cooling. During the cooling process, the laser sensor measures the surface temperature of the workpiece, and the moving bracket drives the metal hose to circulate along the surface of the part and change the blowing position and blowing direction. After cooling, the robot gripping system 5 places the product on the dynamic balancing machine 11 for inspection. After passing the inspection, the robot gripping system 5 transfers the product to the automatic transfer system 9, and the AGV automatic delivery system 10 delivers the product to the next workstation.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, adjustments or equivalent substitutions can be made to the arrangement, control logic, gripping method, cooling method, number of heating devices, and transport path of each device without departing from the concept of the present invention; all such adjustments or substitutions should fall within the protection scope of the present invention.
