[0018] Furthermore, marking the fixed point position of the track on the ground includes:

Since the end plane of the leaf-in-box and the large web are two mutually perpendicular surfaces, and when on the leaf-in-box supporting fixture, it is necessary to ensure that it is vertical, so according to the end plane of the leaf-in-box and the large web plane, create the other two reference planes, and collect the two first limit points for the large web of the leaf-in-box on the bottom plate, and the two second limit points at the end of the leaf-in-box, and use their connecting lines to create A second datum plane and a third datum plane perpendicular to the first datum plane are constructed to create a coordinate system.

Then the fixture digital model is imported into the measurement software, and a corresponding coordinate system is created in the software according to the coordinate system in the real space, so that the coordinates of the upper limit points of the remaining fixtures on the digital model can be obtained. During installation, the actual position is adjusted according to the coordinates in the software to ensure that the final installation and debugging of the fixture reaches a high-precision level. After the subsequent installation is completed, the actual coordinates of the limit points can also be collected for deviation query and adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

For example, they may refer to fixed, detachable, or integral connections; they may refer to mechanical or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] like Figure 1 As shown: A modular blade assembly tool installation and debugging method includes the following steps:

[0045] Create a track plane and fix all the tracks at the bottom of the tooling according to the track plane;

[0046] Install the bottom plate of the box-in-the-blade support fixture on the track and keep the top plane of the bottom plate at the same horizontal plane, which serves as the first reference plane;

[0047] Collect two first limit points of the large web of the blade mid-box and two second limit points of the blade mid-box end on the bottom plate, create a second reference plane and a third reference plane perpendicular to the first reference plane by connecting the two first limit points, and create a coordinate system with the first reference plane, the second reference plane and the third reference plane;

[0048] Import the blade tooling digital model into the measurement software and create a corresponding coordinate system in the software;

[0049] When installing the rest of the tooling, adjust its actual position according to the coordinates of each limit point on the tooling digital model;

[0050] After the tooling is installed, all limit point coordinates are collected and deviations are queried and adjusted with the limit point coordinates on the tooling digital model.

[0051] By creating a track plane, first fix the track according to the track plane, then install the base plate of the leaf box support fixture, keep the top of the base plate at the same horizontal plane, thereby establishing the first reference plane, and then collect the limit for the leaf box on the base plate. Since the end plane of the leaf box and the large web are two mutually perpendicular surfaces, and when it is on the leaf box support fixture, it is necessary to ensure that it is vertical, so according to the end plane of the leaf box and the large web plane, create another two reference planes, and collect the two first limit points for the large web of the leaf box on the base plate, and the two second limit points at the end of the leaf box, and use their connecting lines to create a perpendicular to the first base plane. The second and third datum planes of the reference plane are used to create a coordinate system. Since the bottom plate of the leaf box support fixture has been fixed, the position of the coordinate system in the real space has been fixed. Then the fixture digital model is imported into the measurement software, and the corresponding coordinate system is created in the software according to the coordinate system in the real space, so that the coordinates of the upper limit points of the remaining fixtures on the digital model can be obtained. During installation, the actual position can be adjusted according to the coordinates in the software to ensure that the final installation and debugging of the fixture reaches a high-precision level. After the subsequent installation is completed, the actual coordinates of the limit points can also be collected for deviation query and adjustment.

[0052] In this embodiment, creating the orbital plane includes:

[0053] Establish a geodetic coordinate system through laser ranging and leveling to create a geodetic horizontal plane;

[0054] Mark the fixed points of the track on the ground;

[0055] Place the track according to the marked fixed point positions to complete the initial positioning of the track;

[0056] The coordinates of the top of the track are collected in the geodetic coordinate system, and the highest point in the horizontal direction is used as the origin to create a track plane parallel to the geoid.

[0057] Since the track plane is the basis, you can first create the geoid, then place the track on the ground according to the position of the track's fixed point, and then create a track plane parallel to the geoid according to the highest point in the horizontal direction of the track. During installation, adjust all track planes to be in the same plane.

[0058] Among them, marking the fixed point position of the track on the ground includes:

[0059] Import the plane coordinate system of the track fixed point into the measurement software;

[0060] The fixed point positions of the track are marked on the ground using a laser tracker, a target ball and a positioning base.

[0061] When importing the fixed point coordinates of the track, since the track can only be placed on the ground according to the fixed point, its height cannot be guaranteed. Therefore, when importing the coordinates at the beginning, ignore its height information and only import the plane coordinate system.

[0062] In this embodiment, the bottom plate of the box-in-the-blade support fixture is installed on the track, and the top plane of the bottom plate is kept at the same horizontal plane, including:

[0063] Using the track plane as a reference, install the bottom plate of the blade-in-box support fixture;

[0064] Use the laser tracker and target ball to adjust the level of the top surface of the base plate and keep it at the same level.

[0065] Among them, according to the coordinates of each limit point on the tooling digital model, its actual position is adjusted, including:

[0066] Prepare several target ball bases and fix the target ball bases on the ground and / or wall;

[0067] Use a laser tracker and target sphere to collect the actual coordinates of the fixed target sphere base;

[0068] In the measurement software, set up single-point measurement and generate several positioning points at the corresponding coordinate positions;

[0069] During installation, test the actual distance between each limit point and several positioning points, determine the actual coordinates of each limit point, compare them with the coordinates in the test software, and adjust their actual positions.

[0070] During installation, ensure that the actual distances between the limit point and at least four positioning points can be measured.

[0071] Since it is necessary to constantly measure the actual coordinates of the limit points during installation to compare them with the coordinates in the digital model of the measurement software to ensure the installation accuracy of the assembly tooling, it is necessary to conveniently measure the actual coordinates of the limit points. After establishing the coordinate system in the actual space, several target sphere bases are fixed in the space. The position of the target sphere base is determined by the laser tracker and the target sphere, that is, the actual coordinates of the target sphere base are determined. Subsequently, the distance between the limit point and several positioning points can be tested by the multi-point distance positioning method to determine its coordinates in space. During the test, it is necessary to ensure that the actual distance to at least 4 positioning points can be measured in real time to ensure the coordinates of the calculated limit points. If the laser is blocked during the installation process, the laser tracker can be moved to the measurable area, and the area can simultaneously collect the coordinates of most target sphere bases. During the actual installation process, 10 target sphere bases can be set to be fixed at different positions in the three-dimensional space.
