Description

Technical Field

[0001] The utility model relates to the technical field of filter processing, in particular to a surface grinding device for filter preparation. Background Art

[0002] The filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency point of a specific frequency in the power line or the frequency outside the frequency point to obtain a power signal of a specific frequency, or eliminate the power signal after a specific frequency. However, the filter is generally formed by casting, which will produce more burrs on the surface of the filter, and its surface needs to be polished. The traditional surface polishing device for filter preparation adjusts the position of two electric push rods manually or automatically to clamp the two sides of the filter and apply a uniform clamping force. When polishing, the position of the grinding disc composed of a grinding wheel or a sanding belt is adjusted to polish the surface of the filter. There are some problems. The traditional surface polishing device for filter preparation may apply uneven force to the filter through the clamping method of two electric push rods, and adjusting the clamping force may not be convenient or accurate. At the same time, when adjusting the position of the grinding disc for polishing, it is impossible to ensure that the force and grinding depth of each grinding position are completely consistent, which is prone to inconsistency in the flatness and processing accuracy of the filter surface. For this reason, we propose a surface polishing device for filter preparation. Utility Model Content
