Embodiment Construction

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

[0039] like figure 1 As shown, the laser shot peening-shape correction method for annular parts according to the present invention includes 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 of the correspondence between laser parameters, shot peening paths and average curvature; the laser parameters and shot peening paths are adapted to the shape correction requirements of ring parts ;

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

Abstract

The invention provides a laser shot peening strengthening-shape correction method and an integrated device for ring parts, comprising the following steps: obtaining the average curvature change data of the shape correction area through a laser shot peening shape correction test, establishing laser parameters, Shot peening path and average curvature correspondence database; laser peening is performed on ring parts with residual compressive stress requirements. After laser peening, the deformation of the inner hole of the ring part is obtained, and the data processing system obtains the curvature data of each point of the inner hole; the data The processing system establishes the calibration area for each point of the inner hole that does not meet the accuracy requirements, and calculates the average curvature of the calibration area; uses the laser parameters and shot peening path obtained by matching the average curvature of the calibration area with the database, and corrects the shape of the ring part. area. According to the change of the curvature of the inner hole after shot peening, the invention adjusts the laser process parameters to perform shot peening correction, and realizes the control of the shape precision of the inner hole.

Description

technical field [0001] The invention relates to the field of laser strengthening, the field of laser shot peening shape correction or the field of laser automatic processing equipment, in particular to a laser shot peening and shape correction method for annular parts and an integrated device thereof. Background technique [0002] Ring parts are key basic parts that are widely used in the industrial field. With the rapid development of the equipment manufacturing industry, there are more and more types of ring parts, and the demand is also increasing. Among them, annular 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, vibration is very easy to occur during the processi...
