The combined machining-based device comprises a burnishing part, a support part, a base part, a sleeve, a burnishing body shell, a force measuring bolt, a gasket, a spring, a force transmission rod, a supporting ring, a burnishing ball, a check ring, a support body, a guide groove piece, a base body and an industrial personal computer. The turning and burnishing are carried out at the same time through an integrated combined machining device, the required burnishing force is accurately controlled by adopting the force measuring bolt and the industrial personal computer, and special burnishing equipment is saved; and the structure is simple, cost is low, and operation is easy; and the two sets of ball burnishing parts are arranged, the burnishing force can be independently adjusted, meanwhile, acting force is applied to themachined surface one by one, so that the burnishing effect is further enhanced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing surface quality control method based on a combined processing device. Background technique [0002] Machining, as a means of finishing parts, often has low surface integrity quality, which is prone to produce tensile residual stress and high surface roughness values. In order to overcome these problems, the ball rolling process is one of the most commonly used treatment methods, which can obtain better surface roughness, and the residual compressive stress generated can reach the range of tens of microns below the machined surface, which greatly affects the secondary surface of the machined parts. Surface layers can have a beneficial effect. However, the tumbling process is usually carried out after conventional cutting and requires special ball tumbling equipment. A ball rolling device is disclosed in the patent US 005826453A, but the device has the following ...

AI Technical Summary

Problems solved by technology

A ball rolling device is disclosed in the patent US 005826453A, but the device has the following two deficiencies: (1) the device needs to be rolled after the turning process is completed, and the integrated processing of turning and rolling cannot be realized (2) The required rolling pressure of the device is provided by high-pressure water, which requires an additional high-hydraulic water device, which increases the composition of the whole device, complex structure, and high cost

The International Journal of Precision Engineering and Manufacturing published an article: Some insights on Combined Turning-Burnishing (CoTuB) process on workpiece surface integrity. Although the combined processing device is used in the article, its shortcomings include: (1) the elastic force of the spring passes through The 3 supporting rings are passed to the rolling ball, but during the rolling process, the rolling ball is in contact with the surface of the workpiece due to random force, which will cause the rolling ball to deviate, and cannot be rolled normally, which will cause local force on the workpiece (2) Lack of the feedback function of the rolling force, the size of the required rolling force can only be adjusted by manually adjusting the screw-in length of the force-measuring bolt, the error is large, and the rolling force value cannot be accurately controlled; ( 3) Using a set of rolling devices is not conducive to adjusting the rolling position and cannot achieve the best rolling effect

The above-mentioned prior art has the following problems in practical application: the tumbling process is usually carried out after the conventional cutting process, which requires the use of special ball tumbling equipment and repeated rolling, which has problems such as high cost, time-consuming and complicated process , which brings inconvenience to industrial production and needs to be further improved and perfected
