Problems solved by technology

When the existing honing rods process high-precision blind holes, the machining accuracy is difficult to guarantee. For example, the design requirements of the high-precision deep blind holes on the valve core are as follows: In the range of depth greater than or equal to 94.5mm, the hole meets the roughness Ra0.6μm, roundness 0.0025mm, straightness 0.0025mm, the existing honing rod is difficult to process accurately, and the processing efficiency is low

Abstract

The invention discloses an automatic reciprocating-type electric honing bar used for precision machining of a blind hole, and relates to the technical field of electric tools. The honing bar comprisesa honing main body, a transmission component, a driving motor and a control module; the honing main body comprises an oil cylinder barrel body; a sliding piston is arranged in the oil cylinder barrelbody; an inner magnetic ring sheathes the middle part of the sliding piston; a wear-proof ring and a sealing ring respectively sheath two ends of the sliding piston; a honing sleeve comprises a honing sleeve main body and a lapping stick; the inner side of the middle part of the honing sleeve main body is provided with an outer magnetic ring; and the transmission component comprises a first transmission piece and a second transmission piece. The automatic reciprocating-type electric honing bar disclosed by the invention has the advantages that the integral structural design is skillful; the sliding piston in the oil cylinder barrel body is controlled by oil pressure to move front and back, and under a very powerful mutual attraction between two groups of inner and outer magnetic rings, when the sliding piston moves front and back in the oil cylinder barrel body, the external honing sleeve main body does synchronous fore-and-aft reciprocating motion, and thus, the honing sleeve does reciprocating motion in the blind hole while revolving on own axis, and the effect of automatically honing the blind hole efficiently is achieved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an automatic reciprocating electric honing rod for finishing blind holes. Background technique [0002] A blind via is a via that connects the surface layer and the inner layer without penetrating the entire board. Blind holes are located on the top and bottom surfaces of the printed circuit board and have a certain depth for the connection between the surface circuit and the underlying inner circuit. The depth of the hole usually does not exceed a certain ratio (aperture). The installation, use, debugging, maintenance, processing, repair, testing and other operations of deep hole and blind hole parts are often encountered. In some traditional processing methods, such as using large machinery or making special planes, or disassembling parts and transporting them to It is sometimes difficult for the manufacturer or the designated operation place to operate, or it will resu...
