Description

Technical Field

[0001] The invention relates to the technical field of fine component assembly, and in particular to a flexible adjustment mechanism for the position and posture of engine horizontal assembly parts. Background Art

[0002] In order to achieve adaptive and safe engine assembly and adjustment, ensure assembly quality and improve production efficiency, an adaptive docking system for engine parts one and two was constructed. In this system, part one is docked and assembled with part two whose position and posture are fixed through a multi-degree-of-freedom adjustment device. Among them, the position and posture adjustment device of part one is a six-degree-of-freedom parallel platform, commonly known as a stewart platform, which is a general-purpose device. The adaptive assembly process of engine parts one and two includes two stages: automatic adjustment of the position and posture of part one and docking and positioning of part one and part two. In the automatic adjustment stage of the position and posture of engine part one, the six-degree-of-freedom parallel platform and part one are rigidly connected to achieve efficient and high-precision posture adjustment of part one. However, the assembly accuracy requirements of engine parts one and two are high, and the minimum matching clearance can reach 0.02mm. The matching clearance of different products is also different. Therefore, in the docking and positioning stage of engine parts one and two, there is a constraint of a small matching clearance. If the rigid motion is maintained, it may cause rigid contact between engine parts one and two, damage the assembly, and generate unnecessary quality and safety risks.

[0003] According to the search, patent CN 112122917 A discloses a method for precise matching of engine assemblies, which includes two engine assemblies to be assembled, two six-degree-of-freedom flexible parallel platforms, two binocular vision systems and a laser tracker. This patent places the two engine assemblies to be assembled on two six-degree-of-freedom flexible parallel platforms respectively, and rotates the two flexible parallel platforms respectively, so that the pins and pin holes of the two engine assemblies to be assembled are completely imaged in the binocular vision system. Through image acquisition, image processing, and three-dimensional reconstruction, the rigid conversion relationship between the pin holes and the pins on the flexible parallel platforms is obtained, and the target position of the engine assemblies to be assembled is obtained by solving, and one-time assembly is performed. The device includes a translation fine-tuning device, a lifting fine-tuning device, a pitch fine-tuning device, a yaw fine-tuning device and a rotation fine-tuning device, which can meet the multi-degree-of-freedom attitude adjustment requirements of the cabin docking process. However, this patent does not highlight the flexible attitude adjustment capabilities of the two assemblies to be assembled.

[0004] Patent 201610490269.1 discloses a multi-degree-of-freedom cabin attitude adjustment device, which includes a base, a lifting base, a pitch and yaw base, a rotating plate, a supporting wheel seat, a rotating shaft, a translation fine-tuning device, a lifting fine-tuning device, a pitch fine-tuning device, a yaw fine-tuning device and a roll fine-tuning device. The invention device can achieve multi-degree-of-freedom adjustment such as pitch, yaw, and roll. However, the torque input of each adjustment mechanism of the device is input through a hand wheel, that is, it is adjusted manually, and automatic control is not achieved.

[0005] In view of the above problems, the present invention proposes a flexible adjustment mechanism for the posture of horizontally assembled engine parts. The mechanism has a reasonable and compact structure and stable performance. It can realize three-degree-of-freedom flexible adjustment of the posture of engine parts. At the same time, it can detect the stress conditions of the engine parts during the posture adjustment process in real time to prevent rigid collision and extrusion between engine parts one and two.

[0006] In order to solve the above technical problems, the present invention proposes a flexible adjustment mechanism for the position of horizontal engine assembly parts. During the docking and positioning process of engine part one and part two, the engine part one has a three-degree-of-freedom flexible adjustment capability. At the same time, the stress conditions during the docking and positioning process of engine part one and part two can be detected in real time, thereby realizing flexible adjustment of the position of engine parts during the docking and positioning process, preventing collision and extrusion between engine part one and part two, and reducing product quality risks.

[0007] Engine component 1 and component 2 are usually assembled in two states: vertical and horizontal. The process is to align the equal number of connection holes on the flange surface of component 1 and the butt surface of component 2, and then connect and fix them with fastening bolts under the condition that the matching dimensions of component 1 and component 2 meet the requirements and the axes coincide. The present invention takes the horizontal assembly of engine component 1 and component 2 as the background and proposes a specific solution. Summary of the invention
