A device and method for detecting and determining the straightness of the width of a square guide rail

Abstract

The invention discloses a device and method for detecting and determining the straightness of the width of a square guide rail, including a workbench, a controller, a double linear guide rail and a transmission motor. Connected by a ball screw, a measuring device is installed on the workbench at the front and rear sides of the detection platform, the measuring device and the transmission motor are connected with the controller, the controller is connected with a data processor, each measuring device is connected with the data processing connected to the device. The beneficial effects of the present invention are: by using two measuring devices to detect the two surfaces of the square guide rail at the same time, the flatness of the two surfaces of the square guide rail can be quickly judged, and the width of the square guide rail can also be detected at the same time, which is convenient for judgment Regarding the straightness or curvature of the square guide rail, the present invention also has the advantages of wide application range, easy operation, high detection accuracy and high efficiency.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a device and method for detecting and judging the straightness of the width of a square guide rail. Background technique [0002] The straightness of the square guide rail plays a very important role in improving the precision of machine manufacturing and installation and prolonging the working life of the machine. The straightness error of the machine tool guide rail directly affects the processing quality of the parts. There are many methods for detecting the width and straightness of square guide rails in the prior art, such as square ruler detection, level instrument detection, steel wire and microscope detection, etc., but these detection methods or corresponding detection devices are too complicated in structure and inconvenient to operate , the efficiency is not high, or the detection accuracy is low. [0003] The patent application number 201410311584.4 discloses a ...

AI Technical Summary

Problems solved by technology

The detection method has the disadvantages that it can only detect and determine the unevenness of one of the two surfaces of the guide rail at one time, and at the same time cannot detect the width of the guide rail and has a large error in the detection system.

[0004] Aiming at the relevant technical problems existing in the prior art, no effective solution has been proposed yet
