Problems solved by technology

However, the special chuck not only increases the production cost, but also cannot fully guarantee the clamping of the oval tube. Secondly, adjusting the chuck will increase the labor of the production personnel, which is not conducive to large-scale processing and production.

Embodiment Construction

[0030] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0031] Such as Figure 2~4 As shown, the present invention provides a preferred embodiment of a method for aligning an elliptical pipe, wherein figure 2 is the principle block diagram of the alignment method, image 3 It is the detection indication of the correct method Figure 1 , Figure 4 It is the detection indication of the correct method Figure II .

[0032] A method for aligning an elliptical tube. The elliptical tube is clamped horizontally before the aligning operation. The steps include:

[0033] S1. Set the top view surface of the elliptical tube as the reference surface, set two detection points on the reference surface, the detection points are respectively arranged on both sides of the center line of the reference surface, and the horizontal distance to the center line are equal, and measure the height difference and ...

Abstract

The invention relates to the field of tube laser cutting, in particular to an oval tube alignment method. An oval tube is horizontally clamped before the alignment operation. The oval tube alignment method comprises the steps of 1, setting the top-view surface of the oval tube as a reference surface, arranging two detection points on the reference surface, and measuring the height difference and the horizontal distance between the two detection points; 2, working out an alignment rotating angle for eliminating the height difference; 3, rotating the oval tube according to the alignment rotating angle, and completing the alignment operation. The invention further relates to a laser cutting device for the oval tube. The alignment operation is carried out on the oval tube, the oval tube is clamped in an alignment mode according to the detection result and then is cut, the requirement for processing production is met, it is ensured that the cut contour position precision is within the reasonable error range, and the processing production yield is improved; the laser cutting generality is higher, and the tube purchase, transportation and storage cost and conditions are lowered.

Description

technical field [0001] The invention relates to the technical field of pipe material cutting, in particular to a method for aligning an elliptical pipe and a laser cutting device. Background technique [0002] Such as figure 1 As shown, due to the particularity of the tube shape, the surface of the elliptical tube is a curved surface. When the chuck is used to clamp the surface of the elliptical tube, it is easy to cause the clamping angle to be inaccurate, and it is difficult to clamp the elliptical tube (that is, the long axis of the elliptical tube section). Or the short axis is in the horizontal direction), and the cut contour is different from the pre-programmed position, which will cause the center position of the cutting contour to shift, reduce the pass rate of processing production, and even damage the cutting head. [0003] In order to solve the above-mentioned problem that it is difficult to clamp the elliptical tube, it is necessary to replace the special chuck,...
