Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0039] Such as figure 1 As shown, the laser shot peening strengthening-shaping method for annular parts of the present invention comprises the following steps:

[0040] Step 1: Obtain the average curvature change data of the shape correction area through the laser shot peening shape correction test, and establish a database corresponding to the laser parameters, shot peening path and average curvature; the laser parameters and shot peening path are suitable for the shape correction requirements of ring parts ;

[0041] Step 2: Select laser parameters according to the strengthening requirements of the residual compressive stress of the ring part for shot peening. At the same time, the industrial camera 9 detects the deformation of the inner hole after shot peening and tra...

Abstract

The invention provides a laser shot peening strengthening-shape correcting method for an annular part and an integrated device thereof. The method comprises the following steps that average curvaturechange data of a shape correcting area is obtained through a laser shot peening shape correcting test, and a database of the corresponding relation of laser parameters, a shot peening path and the average curvature is established; after laser shot peening strengthening laser shot peening is carried out on the annular part with the residual compressive stress requirement, the deformation amount ofan inner hole of the annular part is obtained, and a data processing system obtains curvature data of all points of the inner hole; the data processing system establishes the shape correcting area forall points, not meeting the precision requirement, of the inner hole, and the average curvature of the shape correcting area is calculated; and the database is used for matching the laser parametersand the shot peening path obtained by the average curvature of the shape correcting area, and the shape correcting area of the annular part is corrected. According to the change of the curvature of the inner hole after shot peening strengthening, the laser process parameters are regulated and controlled for shot peening shape correcting, and the shape precision of the inner hole is controlled.

Description

technical field [0001] The invention relates to the field of laser strengthening or laser shot peening shape correction or the field of laser automatic processing equipment, in particular to a laser shot peening strengthening-shape correction method for ring parts and an integrated device thereof. Background technique [0002] Ring parts are key basic parts widely used in the industrial field. With the rapid development of the equipment manufacturing industry, there are more and more varieties of ring parts, and the demand is also increasing. Among them, ring parts such as bearing rings and flanges are used as key connection, transmission, slewing and supporting structural parts, and are widely used in major equipment manufacturing fields such as aerospace, wind power generation, high-speed rail, ships and high-end CNC machine tools. However, due to the thin wall thickness and poor rigidity of the annular parts, vibrations are easily generated during the processing process, ...
