Double-precision honing device

Abstract

The invention discloses a double-precision honing device. The double-precision honing device comprises a honing base body, a push rod and a mandril assembly. A plurality of coarse oil stone grooves and fine oil stone grooves are formed in the outer circumference of the front end of the honing base body. A coarse oil stone base and a fine oil stone base are arranged in each coarse oil stone groove and each fine oil stone groove respectively, each coarse oil stone base is provided with a coarse honing oil stone, and each fine oil stone base is provided with a fine honing oil stone. Coarse oil stone pin holes and fine oil stone pin holes are formed in the coarse oil stone grooves and the fine oil stone grooves respectively. The push rod is provided with a shaft shoulder, and the coarse oil stone pin holes and the fine oil stone pin holes are placed in the front side and the rear side of the shaft shoulder respectively. Pins are arranged both in the coarse oil stone pin holes and the fine oil stone pin holes, and a ball pin is arranged between each pin and the shaft shoulder of the push rod. According to the double-precision honing device, the push rod, the pins and the ball pins are matched, the positions of the coarse honing oil stones and the positions of the fine honing oil stones in the radial direction can be adjusted, machining of two sorts of precision can be conducted on the same circular hole through the entire device, machining efficiency is improved, machining cost is lowered, and service life is prolonged.

Description

technical field [0001] The invention relates to a honing device, in particular to a double-precision honing device which can be adjusted according to the size of a processed hole and can process different precisions in the same hole, and belongs to the technical field of mechanical honing. Background technique [0002] In order to improve the smoothness of the round hole, it is usually necessary to grind the round hole; the existing honing tool, such as the document with the application number 201220458728.5, discloses a honing tool, which includes a shank, a honing head and a connecting shank and The rotating shaft of the honing head, this honing tool cannot radially adjust the rollers on the honing head, and can only process holes with a fixed diameter, and can only process one type of precision, so the processing cost is high; and honing The roll on the head will be subject to a large radial pressure during grinding, which will increase the wear and reduce the service lif...
