Abstract

The invention relates to a universal grinding device. Along with increase of machining requirements, the requirement on the machining precision of certain inner holes cannot be effectively met by commonly used electrolytic polishing and magnetic grinding. A grinding head is arranged at one end of a grinding shaft of the universal grinding device, and a magnetic block is arranged at the other end of the grinding shaft and is inserted into an electromagnetic coil assembly; a shell is arranged on the outside of the grinding shaft, a grinder body and grinding shaft sleeves at two ends of the grinder body are welded together to form the shell, and the grinding shaft sleeves are connected with a power transmission mechanism; ejector blocks are arranged on the opposite inner walls of the grinder body, a linear bearing is mounted on a part, which is arranged in the grinder body, of the grinding shaft, regulating spring assemblies are arranged among the linear bearing and the ejector blocks, and regulating screws are mounted among the ejector blocks and the grinder body. The universal grinding device has the advantages that the grinding shaft sleeves and the grinder body are in rotating states, so that the grinding depth of the grinding head can be guaranteed, holes of workpieces can be machined in a 360-degree range, the machining progress is greatly improved, and the roughness of the surface of each ground inner hole can reach Ra0.05.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a universal grinding device. Background technique [0002] Commonly used surface precision processing methods for inner holes include electrolytic polishing, magnetic grinding, etc. Electrolytic polishing is mainly used for surface treatment of conductive materials, the surface finish can reach Ra0.05, but the dimensional accuracy is low. Magnetic grinding uses the power of the magnetic field to transmit to the stainless steel grinding needle to make the workpiece rotate at a high frequency, and finally achieve the effect of quickly removing burrs and dirt from precision workpieces. The surface roughness value can reach Ra0.1-Ra0.01. But in actual work, it is difficult to achieve such high precision. With the improvement of processing requirements, the commonly used electrolytic polishing and magnetic grinding cannot meet the processing accuracy requirements of some inner holes. Therefo...
