Three-coordinate positioner with large stroke, high rigidity and high precision

Abstract

The invention discloses a three-coordinate positioner with large stroke, high rigidity and high precision. A main pillar and an auxiliary pillar are arranged on a base; a main pillar is provided with a Z-axis transmission unit; a Z-axis telescopic column is connected with the main pillar by the Z-axis transmission unit; the Z-axis telescopic column is connected with the auxiliary pillar by a roller sliding block; the Z-axis telescopic column is provided with an X longitudinal sliding plate and a Y transversal sliding plate; the X longitudinal sliding plate is provided with an X-axis transmission unit; the Y transversal sliding plate is provided with a Y-axis transmission unit; the Y transversal sliding plate is fixed with a bulb clamping device or vacuum adsorption equipment; a process bulb is arranged in the bulb clamping device; the positioner is controlled by a control system; and the main pillar and the auxiliary pillar are provided with lift working tables. The invention can make movement in three directions of X, Y and Z, can realize linkage control and has high movement precision and accurate positioning; the positioner has big safety working stroke and high rigidity; the Z direction is provided with a displacement and force sensor positioner, and thereby, the three-coordinate positioner has stable and reliable support. The three-coordinate positioner is the basic unit for the digital posture adjustment of aircraft components.

Description

technical field [0001] The invention relates to a three-coordinate positioner with large stroke, high rigidity and high precision. Background technique [0002] A large number of curved surfaces and large components with irregular geometric shapes are used in military, aviation, aerospace, ship and other fields. Their assembly process is generally that the parts are first assembled into relatively simple assemblies, then assembled into more complex segments and parts, and finally the parts are butted into a complete product. During the docking assembly of various components, it is required that each component can move within a large range, and the adjustment accuracy of each component’s pose is required to be high, so as to ensure the assembly accuracy and shape coordination accuracy requirements of the docking components. [0003] The butt joint assembly of components is realized by certain tooling. Traditional assembly of large parts uses fixed and rigid tooling. Rigid ...

AI Technical Summary

Problems solved by technology

Rigid chemical equipment is specially designed for specific structures, and every detail needs to be considered, resulting in complex overall structure, large volume, and single purpose

The degree of automation of tooling is low, the workload of manual assembly is heavy, the production cycle is long, and the cost is high

[0004] In the manufacture of large aircraft, traditional rigid tooling cannot meet the requirements of large parts docking assembly, and flexible tooling with reconfigurable functions has attracted more and more attention
