Embodiment Construction

[0023] In the structure of a certain type of satellite antenna tower in my country (as attached Figure 1a ) in the structural assembly, the accuracy of product assembly can be well guaranteed by using the present invention. The antenna tower structure consists of a structural plate consisting of three fixed faces (e.g. Figure 1b shown), a structural plate consisting of two fixed surfaces (such as Figure 1c As shown), the two structural plates are assembled to form a five-sided tower body support plate, and a top plate is installed on the tower body support plate,

[0024] attached figure 2 Shown is the payload support assembled on the tower body. The ultimate purpose of adjusting the structure of the antenna tower body is to ensure the installation accuracy of the payload support.

[0025] The following introduces the application of this technology in actual assembly, specifically divided into two cases: the embedded parts at the installation place of the payload support...

Abstract

An antenna tower structure virtual assembly method based on scene visualization comprise the steps of 1 drawing a theoretical three-dimensional model of an antenna tower structure assembled in place according to the design drawing requirement of the antenna tower structure, identifying the theoretical position of an effective load support installing holes on a structure plate; 2 performing entity assembly on the antenna tower structure; 3 using a laser tracker or a laser radar to measure the actual position of an embedded aluminum block on the structural plate after entity assembly; 4 drawing the position of an actual embedded aluminum block on the theoretical three-dimensional model drawn in step 1 according to a measurement result in step 3; 5 calculating the minimum distance between the edge of a drill bit and the edge of the actual embedded aluminum block when an installing hole is machined in the embedded aluminum block according to the theoretical position of the drill bit, judging whether the minimum distance meets the actual drilling and installation requirement or not, completing the assembly of the antenna tower structure if the minimum distance meets the actual drilling and installation requirement, and adjusting the entity assembly position in step 2 and re-performing steps 3-5 if the minimum distance does not meet the actual drilling and installation requirement.

Description

technical field [0001] The invention belongs to the product assembly technology of complex structural form products, especially polyhedron compound angle form, and is applied to the situation where the product posture cannot be judged by using the traditional position and posture measurement method. By using this technology, it can conveniently assist technicians to assemble and adjust the product position It can conduct comprehensive and accurate analysis and judgment, improve the reliability of assembly, and have broad application prospects. Background technique [0002] As a new research field, virtual assembly technology is integrated with various technologies. Its development is closely related to product design methodology, visualization technology, simulation technology, assembly and manufacturing technology, and the development of assembly and manufacturing equipment. With virtual assembly, it is possible to verify the correctness of assembly design and operation, so...
