Method for fast repositioning linear guides with high precision

Abstract

The invention belongs to the field of mechanical manufacture, in particular to a method for fast repositioning linear guides with high precision. The method comprises the steps of: firstly correcting each precision of one linear guide with a laser interferometer, and screwing and fixing the linear guide with a screw bolt; debugging correction table to the other linear guide by taking the former linear guide as a standard guide, and screwing and fixing the other linear guide with a screw bolt; arranging barrier materials along one sides of the two linear guides, wherein clearances are remainedbetween the barrier materials and the linear guides; and filling high-precision positioning glue into the clearances, wherein the positioning glue is solidified to be formed into a glue strip, so that the surface of the glue strip near the corresponding linear guides is the installation reference plane of the linear guides. The method assembles and debugs the straight line degree and the parallelism degree of the two linear guides to be both at 0.005mm, improves the fast motion and the assembly quality of a machine tool, and is convenient and simple for debugging a machining center by simplifying working procedures.

Description

【Technical field】 [0001] The invention belongs to the field of mechanical manufacturing, and more specifically relates to a high-precision and rapid repositioning method of a linear guide rail. 【Background technique】 [0002] The requirements for machining centers in the automotive industry are: high speed, high efficiency, and high precision. In order to improve the processing speed and efficiency, it is necessary to reduce the auxiliary time in the processing of parts; and improving the three-axis rapid movement of the machining center is a necessary condition for reducing the auxiliary time in the processing of auto parts. At present, the speed of domestic horizontal machining centers is within 50m / min; when processing gearboxes, engine blocks, and cylinder heads in the automotive industry, the auxiliary time is greater than the processing time; fast motion accounts for about 75% of the auxiliary time; the rapid time increases , The production tempo is slow, which affect...

AI Technical Summary

Problems solved by technology

The main reason is that it is difficult to ensure the installation accuracy of the installation surface of the linear guide rail during the processing process. The paired width error of the linear guide rail is large, which affects the movement speed of the machining center. It often needs to be corrected by manual scraping, which is not only difficult to process, but also time-consuming. strenuous
