Method and device for magnetic needle magnetic grinding of workpiece with complex shape

Abstract

The invention relates to a method and device for magnetic needle magnetic grinding of a workpiece with a complex shape. The device for the magnetic needle magnetic grinding of the workpiece with the complex shape comprises a bench drill, a workpiece clamping mechanism and a magnetic needle magnetic grinding mechanism; the workpiece clamping mechanism is connected to the bottom of a working shaft of the bench drill, and the magnetic needle magnetic grinding mechanism is fixed to a base of the bench drill; the workpiece clamping mechanism comprises a clamping head, a connecting rod, a rubber sleeve, a fastening bolt, clamping bolts and a n-shaped supporting frame; the clamping head is fixedly connected with the bottom end of the working shaft of the bench drill, the top of the connecting rodis fixed to the working shaft of the bench drill through the clamping head, and a square frame is fixed to the bottom of the connecting rod; the top of the n-shaped supporting frame is connected withthe square frame through the fastening bolt and a fastening nut, and the clamping bolts are connected to the two sides of the n-shaped supporting frame in a threaded mode; and the clamping bolts clamp and fix the workpiece. The method and device for the magnetic needle magnetic grinding of the workpiece with the complex shape have the advantages that the workpiece clamping mechanism is adopted and matched with the magnetic needle magnetic grinding mechanism, the workpiece in a complex shape can be uniformly grinded, the workpiece clamping mechanism and the magnetic needle magnetic grinding mechanism rotate simultaneously, so that the grinding rotating speed is increased.

Description

technical field [0001] The invention belongs to the field of magnetic needle magnetic grinding, and in particular relates to a magnetic needle magnetic grinding method and device for complex-shaped workpieces. Background technique [0002] With the continuous improvement of manufacturing technology, complex shapes and tiny precision parts are constantly being produced and applied to practice, including some applications in special fields, such as aviation, aerospace, navigation and other fields. After processing small and complex parts, some processing textures will remain on the surface of the workpiece, and edge burrs will also occur on the edges and holes. When used in special fields, its performance will be greatly affected. Traditional processing methods, such as grinding with files and sandpaper, can also remove these processing textures and burrs, but they are labor-intensive, time-consuming and labor-intensive, and the efficiency is too low, so they are only suitable...

Problems solved by technology

However, there are still some problems, such as uneven grinding of parts with complex shapes. During the grinding process, as the speed increases, it is easy to collide with the cylinder wall to destroy the original shape, and the efficiency is low.
