Control system of automatic straightener for linear guide rails

Abstract

The invention provides a control system of an automatic straightener for linear guide rails. The automatic straightener for the linear guide rails is at least provided with a straightening pressure head and two supporting parts. The control system firstly builds correction models of the linear guide rails in two vertical directions, connects measuring points positioned on a surface into a continuous curve, counts all curves on the linear guide rails, determines the position coordinates of pressure points of a positive curved surface and two supporting points of a negative curved surface and successive pressing sequences of curve segments according to the curvature of the curve segments, sets the maximal correction quantity of the straightening pressure head and the two supporting parts, then drives the two supporting parts to respectively support against the two supporting points of the negative curved surface of a selected curve segment so that the straightening pressure head presses the pressure points of the positive curved surface of the selected curve segment to carry out straightening operation and saves the correction models, the maximal correction quantities and straightening logs of the linear guide rails to carry out journey compensation variation and data correction when straightening the curve segment of a more secondary priority level so as to carry out high-accuracy and high-efficiency straightening on the linear guide rails.

Description

technical field [0001] The invention relates to the straightening technology of linear guide rails, in particular to a control system of a linear guide rail automatic straightening machine with high precision and high efficiency. Background technique [0002] In many fields of the machinery industry, linear guides are used in many production lines or machine tools to transfer tools or related products required for production. In the manufacture of linear guide rails, the guide rails undergo bending deformation after quenching and grinding to reduce the amount of deformation. Therefore, straightening has become an indispensable process in the processing of linear guide rails. Especially for high-precision guide rails, even a small amount of bending will affect the processing accuracy of the subsequent process, and even cause the finished assembly to fail to meet the accuracy requirements. [0003] In the existing technology, the domestic equipment in the same industry still ...

Especially for high-precision guide rails, even a slight amount of bending will affect the processing accuracy of the subsequent process, and even cause the finished assembly to fail to meet the accuracy requirements

[0003] In the existing technology, the domestic equipment in the same industry still has the following deficiencies: first, the existing alignment equipment cannot accurately determine the position and order of the calibration points, so that the entire calibration process is slow; secondly, the existing alignment equipment The value of the pressing amount cannot be effectively determined, and the underpressure and overpressure of the indenter are corrected during the straightening process, resulting in an increase in the amount of repeated direction operations; moreover, the existing straightening equipment cannot automatically select the support spacing of the curved part on the guide rail , so in the straightening process, the original curved shape is often changed into a new curved state after the initial correction
