Device and method for online detection of natural-state lateral bending of guide rail in straightening process

Abstract

The invention discloses a device and a method for online detection of a natural-state lateral bending of guide rail in straightening process. The method comprises the steps that: a measuring line is fixed on the upper end surface of the guide rail on the straightening platform in the straightening process; the measuring line is arranged in the length direction of the guide rail; a reference measuring block is placed close to the guide rail surface on one side of the guide rail; the reference measuring block is close to the guide rail surface and slides in the length direction of the guide rail; and the lateral bending direction and size of the guide rail in a natural state can be correspondingly obtained by observing and detecting a gap between the reference measuring block and the measuring line. According to the device and the method, the bending of the guide rail in the natural state can be conveniently and rapidly detected online, targeted correction is carried out, intermediate transfer is reduced, collision and scratch are avoided, and the product quality is improved.

Description

Technical field: [0001] The invention relates to a device and method for on-line detecting side bending of a guide rail in a natural state in a straightening process. Background technique: [0002] The linear guide rail is a slender steel piece, and there will inevitably be bending in the natural state during the incoming material and processing process (the bending mentioned here is the side bending of the guide rail surface of the guide rail), in order to ensure that the guide rail after production can meet the needs of users Requirements, it is necessary to carry out multiple straightening processes in production. [0003] The current straightening of linear guide rails is mostly done manually by using a hydraulic straightening machine to correct the bending of the guide rails. On-line inspections are performed to check whether the calibration is qualified. Only a feeler gauge can be used to detect the bending of the guide rail belt under its own gravity. Due to the infl...

[0003] The current straightening of linear guide rails is mostly done manually by using a hydraulic straightening machine to correct the bending of the guide rail. The online inspection is whether the calibration is qualified. Only the feeler gauge can be used to detect the bending of the guide rail belt under its own gravity.

Due to the influence of its own gravity, some guide rail parts with large curvature in the natural state cannot be detected, which brings difficulties to subsequent processing

If you choose to take the guide rail offline to detect the natural state bending, you need to return to the straightening machine to correct according to the test results after the offline detection. After the correction, you cannot check whether the correction is qualified online, and you need to take the guide rail offline to detect the natural state bending. , which increases the man-hours of multiple transfers, greatly reduces production efficiency, and multiple transfers will also increase the risk of bumping and scratching the workpiece
