Specific implementation manner

[0019] The following combines the attached Figures 1 to 3 A further detailed description will be given to the specific implementation manner of a multi - dimensional rapid adjustment and positioning structure of the present invention.

[0020] A multi - dimensional rapid adjustment and positioning structure specifically includes the following parts: 1. Support base: The support base is made of steel plates and steel pipes, and is divided into a chassis 100, a support rod 101, and a stiffening plate 102. The chassis is disc - shaped, with a support rod added in the middle and three stiffening plates attached, which plays a major rigid support role and bears the upper tire rack platform.

[0021] 2. Tire rack platform: The main body is a platform plate 200, which is rigidly connected to the lower support rod 101. An annular adjustment groove is opened on the platform plate for connecting the adjustable fixing mechanism, and the middle protruding cylinder is a bottom support 201, which plays a role in supporting the node.

[0022] 3. Adjustable fixing mechanism: The main body frame 300 is a "concave" - shaped steel frame, which is spliced by steel plates, with attached ears on both sides. Holes are opened on the attached ears, and are connected to the adjustment screw 301 through an adjustment nut 302. There is a long through - slot in the middle of the steel frame, and a bracket support plate 303 is inserted. Connecting holes are opened at both ends of the support plate 303 and are connected to the other end of the adjustment screw 301 through a locking part 304 such as a pin. By rotating the screw adjustment nut 302, the Z - direction position of the bracket support plate 303 can be adjusted. Several clamping screws 305 are also distributed on one side of the steel frame close to the bottom support 201, which plays a role in fixing the bracket. The bottom of the steel frame is fixed to the adjustment slide bar 306, and the other end of the adjustment slide bar 306 is connected to the platform plate through a slide bar adjustment nut 307. The adjustment slide bar 306 can slide and rotate along the annular adjustment groove on the platform plate. By adjusting the position and angle of the adjustment slide bar, the X - and Y - direction positions of the bracket support plate 303 can be driven to change.

[0023] The specific implementation process of the present invention is as follows: 1. Rotate the screw adjustment nut 302 on the adjustable fixing mechanism until the upper surface of the bracket support plate 303 is flush with the upper surface of the bottom support 201.

[0024] 2. Determine the coordinate origin based on the X, Y, and Z coordinate positions of the spatial bracket on the dot diagram. Loosen the screw adjustment nut 307 on the adjustable fixing mechanism and push the adjustment slide 306 to position the adjustable fixing mechanism at the approximate X and Y coordinate positions of the spatial bracket.

[0025] 3. Place the lower wing plate of the six-claw spatial node flat on the bottom support 201, and put the wing plate part of the spatial corbel into the adjustable fixing mechanism to fit with the corbel support plate 303.

[0026] 4. Fine-tune the position and orientation of the slide bar 306 to ensure sufficient Z-axis adjustment space. Tighten the slide bar adjustment nut 307 after adjustment.

[0027] 5. Spot weld the lower wing plate of the six-claw spatial node to the bottom support 201.

[0028] 6. According to the X, Y, and Z coordinate positions of the spatial corbel on the dot drawing, rotate the screw adjustment nut 302 on the adjustable fixing mechanism to drive the corbel support plate 303 Z to move up and down until the spatial position of the lower wing plate of the spatial corbel coincides with the coordinate position on the drawing.

[0029] 7. Assemble the six-claw space node web and rotate the clamping screw 305 to align and fix the web position.

[0030] 8. Assemble the upper wing plate of the six-claw spatial node and check the spatial position and size of the spatial bracket. If there is any deviation, rotate the screw adjustment nut 302 on the adjustable fixing mechanism to adjust it.

[0031] 9. Loosen the clamping screw 305 and remove the six-claw space node for overall welding.

[0032] 10. After the overall welding is completed, place the six-claw space node back on the multi-dimensional quick adjustment positioning structure for dimensional verification.
