Abstract

The invention discloses a portable hob. The portable hob comprises a transmission, a rolling path, a front support guiding block and a rolling needle, wherein the head end of the transmission is matched with the tail end of the rolling path; the rolling path is controlled by the transmission to rotate and operate; a retaining sleeve is sleeved and matched with an outer ring of the rolling path; the rolling needle is arranged on the outer circumferential ring of the sleeved end; the front support guiding block is arranged on the outer circumferential ring at the middle-rear part of the retaining sleeve; a driving motor is axially arranged at the tail end of the transmission; a raised annular table is processed on the circumferential ring at the tail end of the transmission; a rear support guiding block is arranged on the circumferential ring surface of the annular table; the portable hob is separately provided with the driving motor, so that the portable hob has a unique structure and is convenient to carry; two support guiding blocks are arranged at the front part and the rear part of the portable hob, so that the processing precision is increased; an adjusting clamp ring is arranged so as to realize the stretching operation of the axial distance of the retaining sleeve; due to the adoption of an obliquely-inclined detachable structure of the retaining sleeve, the whole rolling needle is convenience and quick for replacement and the integral portability is increased; a spring body is arranged so as to ensure that the rear support guiding block is positioned in an elastic floating state; and in the actual practical process, the buffer introduction during guiding is realized more easily and the guiding accuracy is increased.

Description

technical field [0001] The invention relates to the technical field of machining cutting tools, in particular to a portable hob. Background technique [0002] Rolling processing is to carry out rolling and pressing treatment on the processed surface, which is widely used because of its high processing quality, such as the Chinese invention patent "Ball Rolling Knife" with the patent number CN200920306156.7 (the announcement number is CN201432189Y); 1. Cutter rod, one end of the cutter rod is provided with a groove, the inner side of the ball is rollingly matched with the bearing fixed in the groove, the outer side of the ball is provided with a retaining ring fixed on the groove wall, and the outer side of the ball is in contact with the wall of the positioning hole arranged on the retaining ring Slip fit. The balls in this design have a pin groove structure, that is, the balls are in a suspended state inside, the pin body is easily damaged, and the service life is reduced;...
