Stepless speed regulation micro carving pen with buffering function

Abstract

The invention provides a stepless speed regulation micro carving pen with a buffering function, and belongs to the technical field of electromechanics. The stepless speed regulation micro carving pen comprises a pen tube, a rotating shaft and a tool bit tool, wherein an inner cavity of the pen tube is divided into a mounting cavity and a storage cavity through a partition plate, a mobile power source is arranged in the storage cavity, and a pushing block is slidably connected to the end, close to a pen point, in the mounting cavity; the rotating shaft is connected with the pushing block in a rotating mode, and a rotor is fixedly arranged at the inner end of the rotating shaft; the tool bit tool is fixedly connected to the outer end of the rotating shaft, a stator is fixedly arranged at one end, away from the pen point, of the mounting cavity, and windings are electrically connected with the mobile power source; the stator comprises a plurality of the windings connected in parallel, the rotor comprises a telescopic structure composed of a plurality of cylindrical permanent magnet sets, an avoiding space allowing a stretched rotor to be inserted is formed in the stator, and a reset spring is connected between each permanent magnet set and the pushing block. The stepless speed regulation micro carving pen with the buffering function has the advantages of high engraving precision and the like.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to a stepless speed-regulating micro-carving pen with a buffer function. Background technique [0002] The engraving pen is used for the processing of small-sized stone, wood and other raw materials. The speed of the existing engraving pen is uncontrollable. Moreover, the existing engraving pen cutter head does not have a buffer function. During the actual processing process, the cutter head rigidly contacts the part to be processed. Cause damage to the material to be processed, such as stone tool processing, which is prone to bursting. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the existing technology, and to provide a stepless speed-regulating micro-carving pen with a buffer function. speed. [0004] The purpose of the present invention can be achieved through the following technical sol...
