Problems solved by technology

Since the fibers inside the girder plate are arranged longitudinally, the above-mentioned processing method will inevitably lead to roughening of the surface during the grinding process of the plate and even cause the surface of the plate to tear
[0004] Secondly, due to the large length of the girder slab of the wind blade to be processed, it is also difficult to transport the girder slab to the fixing device. Collisions, jamming, damage to the girder slab or poor docking often occur, making it impossible to continue forward transportation;

Embodiment Construction

[0028] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings. This embodiment is only used to explain the present invention, and does not constitute a limitation to the protection scope of the present invention.

[0029] Such as figure 2 Shown is a grinding method suitable for wind blade girder plates of the present invention, including a stroke driving device on the frame 6 that can drive the grinding head 40 to move horizontally and vertically; the grinding head 40 Grinding movement can be done along the length direction of the girder slab; the grinding motion includes vertical movement and horizontal movement; the rotation mode of the grinding head 40 of the grinding machine is down-pressing rotation along the fiber direction of the girder slab; specifically, for both sides of the girder slab, separate Grinding; when the grinding head 40 of the grinding machine is g...

Abstract

The invention discloses a grinding device suitable for a wind blade girder plate. The grinding device is characterized in that the rotating mode of a grinding head of a grinding machine is press-typerotation in the fiber direction of the girder plate, and it is ensured that the grinding head of the grinding machine grinds girder plate fibers downwards in the grinding process; when the two ends ofthe girder plate are ground, the track of the grinding head of the grinding machine is slash grinding motion in the fiber direction of the girder plate; the slash grinding motion can be divided intovertical direction motion and horizontal direction motion; specifically, the track of the grinding head of the grinding machine along the vertical direction motion is from top to bottom in the heightdirection of the girder plate; when the grinding head of the grinding machine grinds and moves from right to left, the rotating direction of the grinding head of the grinding machine is clockwise; andwhen the grinding head of the grinding machine grinds and moves from left to right, the rotating direction of the grinding head of the grinding machine is anticlockwise.

Description

technical field [0001] The invention relates to the field of production and processing of a wind blade girder plate, in particular to a grinding method and a grinding device suitable for a wind blade girder plate. Background technique [0002] The girder plate 9 is a carbon fiber composite material formed by curing carbon fiber and resin at a high temperature in a mold, and its internal structural fibers 91 contain 85% of which are longitudinally arranged. The effective length of the existing wind blade girder plate is more than 30-60 meters, and the shape required for grinding is as follows figure 1 As shown in the middle girder slab 9, the existing girder slab raw material is a cuboid, and the corners 90 of the finished girder slab need to be removed. Therefore, during the processing, the two ends of the girder slab need to be ground. [0003] There is no special equipment for grinding the girder plate of the existing wind blade, and the abrasive material of cubic boron c...
