Description
Technical Field
The invention relates to the field of magnetic core processing equipment, in particular to an end face grinding machine for a cylindrical magnetic core.
Background
With the development of industrial machinery, automatic equipment is adopted for processing a plurality of workpieces at present. In the field of machining, an end surface grinding machine is a surface machining grinding machine, which is widely applied to the production of various parts by grinding the surface of a workpiece by using a grinding tool (such as a grinding wheel). However, whether the end face machining of one workpiece can be automated by the grinding machine is not only dependent on the difficulty of the end face machining of the workpiece, but also on whether the loading and unloading and clamping of the workpiece can be automated, and the automated machining of the end face grinding machine can be realized only if the two conditions are met simultaneously.
Similar to a cylindrical workpiece such as a cylindrical magnetic core, the end face of the cylinder may have unevenness, and the end face needs to be ground; however, since the cylindrical magnetic core is of a cylindrical structure which is brittle, a production line which is conventionally used cannot be adopted, and therefore, no equipment which can grind the end face of the workpiece exists in the market. At present, the method conventionally used in the industry is to insert a plurality of cylindrical magnetic cores on a mold, and to grind the outer end surfaces of the cylindrical magnetic cores by driving the cylindrical magnetic cores to move relative to a grinding tool (such as a grinding wheel) through the mold. Then, the other end face of the columnar core was polished in accordance with the above-described method. The whole processing procedure has low efficiency and low product percent of pass. The reason is mainly divided into two aspects; 1, the cylindrical magnetic core is different from a conventional cylindrical workpiece, and the magnetic influence among the workpieces of the cylindrical magnetic core is avoided, so that a feeding mechanism capable of overcoming the characteristics of the cylindrical magnetic core is urgently needed; 2, there are no corresponding product clamps on the market for clamping the above cylindrical magnetic cores, and similar workpieces.
