A three-dimensional positioning device for installing an automobile air duct

Abstract

The invention discloses a three-dimensional positioning device for installation of an automobile air pipe. The three-dimensional positioning device comprises a positioning head, the lower end of the positioning head is connected with a positioning head control assembly, and the lower end of the positioning head control assembly is connected with a power assembly; a deviation correcting guide sleeve is arranged in a cavity of the positioning head control assembly, and an air pipe installation workpiece sleeve is fixedly arranged at the top end of the positioning head. In the whole installationand sleeving process, an expansion cavity in the positioning head is used for expanding and retracting, so that positioning of a workpiece is achieved. The designed expansion cavity is a completely symmetric cavity, so that the positioning extrusion force borne by the air pipe installation workpiece sleeve at the same time is completely the same, the stability of the workpiece in the positioning process is guaranteed, and the situation that the workpiece is damaged is avoided. The deviation correcting guide sleeve utilizes the advantages that a closed-loop system is fast in response and high in self-control capacity, and the characteristic that a closed-loop feedback system is matched with electromagnetic conversion is utilized, so that the situation that a coil group self-adjusts the deflection of a metal power connecting rod is achieved, and the precision of workpiece positioning is greatly improved.

Description

technical field [0001] The invention relates to the technical field of installing an automobile air duct, in particular to a three-dimensional positioning device for installing an automobile air duct. Background technique [0002] The mounting bracket of the automobile air duct is used to install and fix the parts of the automobile air duct. The air duct needs to be installed on this part. Sophisticated process. If there is an inclination in the process of connecting the air duct, it is easy to cause the air duct to leak, resulting in poor sealing of the air duct and even causing danger. Most of the current automobile air duct socketing process adopts a semi-automatic socketing method, and artificial pressure is applied to position the pipe sleeve for air pipe socketing. It is inevitable that artificial pressure is not uniform in the whole process, and the accuracy of the positioning process is also very low. The traditional top pressure positioning or clamping positioning...

AI Technical Summary

Problems solved by technology

[0006] (1) The clamping and positioning device of the existing three-dimensional positioning device installed on the automobile air duct cannot meet the requirement of applying equal pressure to the positioning fixture on the surroundings of the installation workpiece sleeve during the clamping process, and cannot ensure that the workpiece is evenly stressed and thus affects the installation of the workpiece The sleeve is positioned smoothly, resulting in inaccurate positioning and flaws in the wedging process of installation

[0007] (2) Most of the existing three-dimensional positioning devices installed in automobile air ducts are driven by humans, and there are also cylinders or hydraulic cylinders used to drive the positioning process, but the linkage rods installed in the cylinders or hydraulic cylinders may appear slightly Deviation, this deviation may lead to loose air duct installation, unstable installation and other conditions
