Problems solved by technology

In the prior art, the method of mutual grinding between the flat plate and the work surface is usually used. This method has high requirements on the flat plate. The precision of the flat plate is usually 0 grade, and the flatness error is within 0.01mm. For large-scale CNC machine tools, such a flat plate can be customized The cost is too high and the difficulty is high. In addition, in the process of mutual research, the disturbance and deformation of the plate due to its own weight will generate a large number of unnecessary scraping and research points, which has great blindness and low work efficiency.

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] see Figure 1-2 Shown, a kind of plane scraping grinding method based on flatness measurement, this scraping grinding method comprises the following steps:

[0025] First, obtain the coordinates of multiple points on the surface to be scraped and grind, and record the abscissa and ordinate of these multiple points in matrix A and matrix B respectively. When obtaining these multiple points, a grid method can be used to obtain them. When the grid method obtains multiple points, such as figure 2 As shown, the reference plane is determined by two straight lines OmX and OO'Y, and the straight lines OX and OY are preferably selected as two lines perpendicular to each other and parallel to the contour edge of the surface to be scraped and ground respectively. When measuring, first measure the outline of each...

Abstract

The invention discloses a plane scraping method based on flatness measurement. The plane scraping method includes acquiring a plurality of points on a surface to be scraped at first; computing the flatness of the surface to be scraped by a visualized software capable of processing and fitting data; then judging whether the surface needs to be scraped or not according to the flatness of the surface to be scraped; fitting a graph of the surface to be scraped and a graph of a reference surface of the surface to be scraped according to the multiple points on the surface to be scraped if the surface needs to be scraped; outputting regions which are higher than the reference surface and are required to be scraped on the surface to be scraped; and scraping the outputted regions required to be scraped by an operator by the aid of a scraping plate. Accordingly, only the portions, higher than the reference surface, on the surface to be scraped need to be scraped, most of areas of the surface to be scraped do not need to be scraped, scraping time is saved, scraping pertinence is improved, scraping efficiency is also enhanced, and requirements on proficiency of the scraping operator are lowered.

Description

[0001] technical field [0002] The invention relates to a plane scraping method based on flatness measurement. [0003] Background technique [0004] The workbench is the positioning surface for machining parts on the machine tool, and its precision is directly related to the machining accuracy of the machine tool. Therefore, the flatness requirements for the workbench of the machine tool are very high. After the workbench is installed, due to assembly errors and other reasons, it is usually necessary to scrape the worktable surface to meet the flatness requirements of the machine tool. In the prior art, the method of mutual grinding between the flat plate and the work surface is usually used. This method has high requirements on the flat plate. The precision of the flat plate is usually 0 grade, and the flatness error is within 0.01mm. For large-scale CNC machine tools, such a flat plate can be customized The cost is too high and the difficulty is high. In addition, in ...
