Embodiment Construction

[0034] There is a left clamping mechanism 3 and a right clamping mechanism 6 on the working platform 4, and the two clamping mechanisms can clamp the long track workpiece 5, and the working platform 4 can drive the long track workpiece 5 to move left or right, which can be realized in the long track. The track workpiece 5 is measured with a point laser sensor at different measurement points, and the motor 2 can drive the left clamping mechanism 3 to realize the rotation of the long track workpiece 5, and the right clamping mechanism 6 follows.

[0035] (1) Install the measured length track workpiece 5 on the working platform 4 through the left clamping device 3 and the right clamping device 6. At this time, the working platform is located on the far right side of the straightening machine, and the left clamping device 3. The right clamping device 6 is fixedly connected with the working platform 4, which is slidingly connected with the straightening machine. The point laser sens...

Abstract

The invention relates to a non-contact straightening point confirming method for the straightness of a rectangular-section long-rail work piece and belongs to a curvature measuring and straightening point confirming method. A point laser is used for measuring data of the straightness of the surface of the long-rail work piece, and then the collected data are processed and calculated in a sagitta mode to form the required compression point position and the supporting point position. The non-contact straightening point confirming method has the advantages of achieving full-automatic measurement and calculation of the whole straightness and the partial straightness of the long-rail work piece on a straightening machine, confirming the points needing to be straightened, achieving measurement on the long-rail work piece and being simple and applicable.

Description

technical field [0001] The invention belongs to a non-contact measurement method for the straightness of a long track workpiece with a rectangular cross section, and mainly proposes a bending degree measurement and straightening point determination method, which is applied to the overall and partial measurement of the long track workpiece of a factory straightening machine. Background technique [0002] At present, when domestic straightening machines straighten long track workpieces with rectangular cross-sections, the straightness of long track workpieces over 3 meters is measured mainly by measuring the curvature of each part with a feeler gauge on a standard flat platen, so as to know A method for overall straightness of long track workpieces. The operator uses feeler gauges of different thicknesses to measure the local high points empirically, and then straightens the high points on the press. Since the long track workpiece is relatively long, there will be many bends ...
