Rapid scribing device and scribing method for surface of cylindrical part

Abstract

The invention belongs to the field of machining, and discloses a rapid scribing device and a scribing method for the surface of a cylindrical part. The rapid scribing device comprises a chuck body; a positioning hole is formed in the center of the chuck body, a positioning pin guide rail is arranged in the positioning hole, a positioning pin sliding block is arranged on the positioning pin guide rail, and a positioning pin is arranged on the positioning pin sliding block and used for positioning a part to be scribed; a scribing point guide rail, a dish-shaped gear and a plurality of bevel gears meshed with the dish-shaped gear are arranged on the chuck body; and the scribing point guide rail is perpendicular to the chuck body, a scribing point sliding block is arranged on the scribing point guide rail, a scribing point is arranged on the scribing point sliding block, the line scribing end of the scribing point right faces the positioning hole, an Archimedes spiral groove is formed in the surface of the dish-shaped gear, and a plurality of chuck jaws are arranged in the Archimedes spiral groove. The bevel gears are rotated to drive the chuck jaws to move, so that the device can adapt to parts of various sizes, lines can be scribed on the surfaces of cylindrical parts of different sizes, the parts to be scribed of the same size can be continuously machined, positioning is not needed during machining every time, and time is saved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a device and method for quickly marking lines on the surface of cylindrical parts. Background technique [0002] The engraving process, or scribing process, is an important process in the bench work. In the fitter work, according to the requirements, use the marking tool to draw the processing boundary line on the blank or semi-finished product, determine the machining allowance of the workpiece, and make the fitter processes such as chiseling, filing and sawing have obvious size boundaries. [0003] At present, the engraving method of the cylindrical surface of the ring part is: use the clamping handle of the ring part to clamp the ring part, and use the engraving knife and milling cutter to carry out the engraving process after the zero position of the part is corrected. This traditional processing method requires the zero position of the part Alignment is carried out, and t...
