[0046] It can be understood that the groove 1407 on the fixed seat 1401 realizes the limiting of the bolt ball joint, prevents the slip of the bolt ball joint, the three fixed clamps 1402 realize the fixation of the bolt ball joint in the installation state, prevent the rotation of the bolt ball joint in the installation process, and the drainage hole realizes the drainage of water, reduces the rust caused by water collection.

[0047] In the embodiment, three sliding grooves 1403 are opened on the upper end surface of the fixed seat 1401, the cross section of the sliding groove 1403 is rectangular, and the sliding groove 1403 is arranged annularly around the central axis of the fixed seat 1401; the fixed clamp 1402 comprises a movable clamp plate 1404 slidingly matched with the sliding groove 1403, the cross section of the movable clamp plate 1404 is , it also comprises a lower clamp plate 1405, a vertical spring type buffer column is arranged in the sliding groove 1403 away from the movable clamp plate 1404, the top end of the buffer column is hinged to one end of the lower clamp plate 1405, the other end of the lower clamp plate 1405 is hinged to the end of the movable clamp plate 1404 away from the fixed seat 1401, and the upper clamp plate 1406 is screwed at one end of the movable clamp plate 1404, the cross section of the upper clamp plate 1406 is "Π" shape, and a sensor module is further arranged on the end surface of the fixed seat 1401.

[0049] It can be understood that the adjustment of the clamping range of the fixed clamp 1402 is realized by the relative sliding of the sliding groove 1403 and the fixed clamp 1402. A vertical spring type buffer column is arranged in the sliding groove 1403 away from the end of the movable clamp plate 1404. The top end of the buffer column is hinged to one end of the lower clamp plate 1405, and the other end of the lower clamp plate 1405 is hinged to the end of the movable clamp plate 1404 away from the fixed seat 1401. Through the above structure, the top end of the upper clamp plate 1406 is always kept horizontal during the movement of the fixed clamp 1402. At the same time, when the upper clamp plate 1406 of the fixed clamp 1402 is closest to the center line of the fixed seat 1401, the upper end surface of the upper clamp plate 1406 is at the lowest height, so that the lower end surface of the upper clamp plate 1406 is coplanar with the upper end surface of the fixed seat 1401. When the support module 14 is coaxial with the auxiliary support module 12 and only supports the bolt ball node through the auxiliary support module 12, the compression resistance of the upper clamp plate 1406 is enhanced, and deformation is prevented.

The fixed support plate is spherical at the end away from the slider. It also includes a buffer rod between the slider and the fixed support plate. The top end is provided with an angle measuring module and a CCD vision sensor. The rotating module is cylindrical and has parallel hinge seats at the top end of the rotating module.

6. The steel space frame bolt ball node installation device according to claim 5, characterized in that: The support is cylindrical with a spherical notch groove at the bottom and multiple telescopic casters arranged in a ring around the central axis of the support. It also includes multiple vent holes that penetrate the support and are arranged parallel to the central axis of the support. The support also includes a fixed crossbar, which is a telescopic rod with one end inside the support and the other end detachably connected to the side support telescopic support column via a buckle.

7. The quality inspection method for the steel space frame bolt ball joint installation device according to any one of the above claims, characterized in that... The method also includes a server connected to the angle measurement module and CCD vision sensor via a network, on which an artificial intelligence quality inspection system is installed. The steps of the method are: a) Install according to the installation method steps of the bolt ball joint, and record the installation process through the vision sensor; b) The data collected by the CCD vision sensor is sent back to the server, and the information of the feature points of the acceptance criteria is extracted by the artificial intelligence quality inspection system; c) After installation, the angle measurement module measures the included angle between the steel pipe members and sends the data back to the server; d) The server extracts information from the feature points of the acceptance criteria using an artificial intelligence quality inspection system; e) The server's AI-powered quality inspection system compares extracted feature point information with data in a standard library to inspect the installation quality of bolt ball joints and generates an inspection report.
