Paraxial tilting rotary table for linear three-coordinate transformation machine

Abstract

The invention discloses a paraxial tilting rotary table for a linear three-coordinate transformation machine. A plane air floating upper disc is connected onto a plane air floating lower disc, the plane air floating lower disc is fixedly supported on a plane air floating base, a worm and gear assembly is arranged in a cavity of the plane air floating base, a worm wheel shaft in the worm and gear assembly penetrates through the plane air floating lower disc to be fixedly connected with the plane air floating upper disc, one end of a worm in the worm and gear assembly is fixed to the lateral wall of the inner portion of the plane air floating base, the other end of the worm is connected with a servo motor I to drive the worm to rotate, so that the worm drives the worm wheel to rotate, and when a screw fastened between the plane air floating upper disc and the plane air floating lower disc is loosened, the plane air floating upper disc is driven to rotate. One side of a rotary table base is connected with a plane air floating base through a tilted supporting shaft in a pivoted mode, the opposite side of the rotary table base is symmetrically provided with two sets of push rod assemblies, and push rods of the push rod assemblies are inserted into grooves and are in rotating connection with groove walls through pivots. The paraxial tilting rotary table effectively improves the load capacity of the linear three-coordinate transformation machine and the measurement accuracy of spacecraft quality characteristic parameters.

Description

technical field [0001] The invention belongs to satellite assembly testing technology, and in particular relates to quality characteristic testing equipment for a spacecraft whole satellite, spacecraft sub-systems and spacecraft components. In addition, the invention can also be used in the fields of complete automobiles and parts, aviation weapons, etc., to complete the quality characteristic test of related products. Background technique [0002] The three-coordinate conversion machine is a general-purpose chemical device for spacecraft quality characteristic testing. Its function is to replace the L-shaped bracket and bracket in the process of spacecraft quality characteristic parameter testing, and realize the automatic positional relationship between the spacecraft coordinate system and the test coordinate system. Convert function. [0003] The three-coordinate conversion machine is divided into two types: a straight-line three-coordinate conversion machine and an arc-...
