Problems solved by technology
However, in the process of continuous quenching of the surface of a cylindrical workpiece by laser quenching, in order to achieve the effect of complete surface hardening, the laser beam must be fed in a spiral manner, which makes the heat-affected zone on the surface of the workpiece overlap and overlap.
This will seriously affect the effect of surface treatment and reduce the service life of parts
Moreover, when processing cylindrical workpieces, the laser quenching process with spiral feed is inefficient due to the large surface area of the workpiece

The invention discloses a cylinder workpiece surface continuous lap-joint-free laser quenching device and a quenching method of the cylinder workpiece surface continuous lap-joint-free laser quenchingdevice. The cylinder workpiece surface continuous lap-joint-free laser quenching device comprises a laser generator, a collimating mirror, a conical lens, a circular ring lens and a circular ring reflector. The cylinder workpiece is sleeved with the circular ring reflector. The laser generator emits a laser beam, the laser beam sequentially passes through the collimating mirror, the conical lensand the circular ring lens to be transmitted to the circular ring reflector, and the laser beam is changed into an annular laser beam to be focused on the outer surface of the cylinder workpiece. Thecylinder workpiece surface continuous lap-joint-free laser quenching device and the quenching method of the cylinder workpiece surface continuous lap-joint-free laser quenching device have the beneficial effects that in the process of processing the outer surface of the workpiece by means of the quenching method, the laser beam continuously and linearly feeds, the situation that heat affected zones are in mutual lap joint is avoided, and the strengthening depth and effect are more uniform.
Description
technical field [0001] The invention relates to the field of laser quenching, in particular to a continuous non-overlapping laser quenching device and a quenching method for the surface of a cylindrical workpiece. Background technique [0002] Research at home and abroad shows that laser surface hardening can significantly improve the strength and fatigue life of the workpiece surface, and improve the performance of the workpiece. However, in the process of continuous quenching of the surface of a cylindrical workpiece by laser quenching, in order to achieve the effect of full surface hardening, the laser beam must be fed in a spiral manner, which makes the heat-affected zone on the surface of the workpiece overlap and overlap. This will seriously affect the effect of surface treatment and reduce the service life of parts. Moreover, when processing cylindrical workpieces, the laser quenching process with spiral feeding is inefficient due to the large surface area of the w...
