Problems solved by technology

[0004] In order to solve the problem that the conventional laser marking device cannot keep the depth and shape of each processed groove unchanged, the present invention adopts a device for laser processing the surface of an involute cylindrical gear, including a base, a sliding The slide table set on the base, the installation shaft rotatably set on the slide table, the laser marker fixed on one side of the base and the electromagnetic chuck fixed on one side of the base, the The installation shaft is used to install the gear, and a collar is fixed on the installation shaft. The outer diameter of the collar is consistent with the base circle diameter of the gear. The driving mechanism rolling on the electromagnetic chuck, the light emitted by the laser marker is always located on the normal line of the involute of the gear

Abstract

The invention is a device for laser processing the surface of involute cylindrical gears, which includes a base, a sliding table slidably arranged on the base, a mounting shaft rotatably mounted on the sliding table, a gear fixed on the mounting shaft, and a fixed mounting shaft mounted on the base. The laser marker on one side and the electromagnetic chuck fixed on one side of the base, the collar is fixed on the installation shaft, the outer diameter of the collar is consistent with the base circle diameter of the gear, and the sliding table is also fixed to drive the collar on the The driving mechanism rolling on the electromagnetic chuck, the light emitted by the laser marker is located on the normal line of the involute of the gear. The invention uses the electric push rod to control the rolling motion of the collar on the electromagnetic chuck. According to the property that the normal line of the involute of the base circle of the gear is always tangent to the base circle of the gear, the laser beam is always in line with the tooth profile of the involute cylindrical gear. The requirement that the tangent is perpendicular to the machined groove can keep the shape and depth of the processed groove unchanged, and improve the precision of the micro-texture of the tooth surface of the laser-processed involute gear.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a device for laser processing the meshing surface of an involute cylindrical gear. Background technique [0002] Friction and wear performance is an important property of the gear surface. Studies have shown that machining microstructures on the gear meshing surface can effectively improve the friction and drag reduction performance of the gear meshing surface. These surface microstructures can not only improve the friction and drag reduction of the gear meshing surface, improve the heat dissipation performance of the gear surface, but also be used to store lubricating oil or debris generated during work. In addition to using methods such as laser shock peening to prepare gear surface micro-textures, laser etching is also a good choice at present. With the development of short-wavelength and short-pulse lasers, laser etching processing technology has become one of the i...
