Ball shell workpiece polishing grinding machine

Abstract

The invention discloses a ball shell workpiece polishing grinding machine. The ball shell workpiece polishing grinding machine comprises a bearing framework, a grinding mechanism and a workpiece fixing mechanism, wherein both the grinding mechanism and the workpiece fixing mechanism are mounted on the bearing framework; the grinding mechanism comprises a grinding device and a lifting device mounted on the grinding device; the grinding device can realize that a grinding wheel swing around a first shaft lever / second shaft lever; the lifting device can realize lifting of the grinding wheel through a second hydraulic cylinder; the surface of a fourth supporting plate of the workpiece fixing mechanism is equipped with a third shaft lever in a penetrating mode; one end of the third shaft lever is connected to a third motor; the other end of the third shaft lever is connected to a fixed disc; and the center position of the surface of the fixed disc is fixedly provided with a magnet disc. Theball shell workpiece polishing grinding machine can realize movement, in the horizontal direction, of the grinding, and motion in a multi-dimensional direction, such as swing around the first shaft lever and swing around the second shaft lever, flexibly controls a motion direction, can perform no-dead-corner grinding on the surface of the workpiece through the grinding wheel, and can realize moresufficient and complete grinding and uniform grinding, so that grinding polishing quality is improved.

Description

technical field [0001] The invention belongs to the field of polishing and grinding equipment, and in particular relates to a polishing and grinding machine for spherical shell workpieces. Background technique [0002] Spherical containers are usually formed by welding two hemispherical shells into a sphere. Spherical containers have many advantages such as uniform force, high load capacity under the same wall thickness, small surface area under the same volume, light weight under the same pressure and volume, etc., and are widely used in aerospace, military, petrochemical and other fields. Since spherical containers are often used to store high temperature, high pressure, corrosive, flammable, explosive, toxic and harmful gases or liquids, the performance of container materials will inevitably be affected by stress, oxidation, corrosion and other factors. In order to ensure the safety and reliability of the container in application, various treatments such as polishing and...

Problems solved by technology

Although this application can fix the ball shell to a certain extent, the fixing method is still not strong enough to make the ball shell rotate, and it is difficult to apply to the polishing and grinding of the ball shell workpiece.
