Abstract

The invention belongs to the field of machinery machining and manufacturing, and particularly relates to a machining device which is used for improving the surface quality and inner quality of a hole of a product. The device for machining the hole comprises a hydraulic system, a control system and a machining system. The machining system comprises a steel ball which is matched with the bore diameter of a workpiece. The hydraulic system machines the hole on the workpiece by extruding the steel ball. The device for machining the hole is mainly characterized in that the hole on the workpiece is machined by extruding the certain-size steel ball. A traditional boring mode is changed, a certain extruding allowance is reserved before extruding, an end-product hole is machined by the fact that the certain-size steel ball is extruded, the end product pass rate of the hole is improved, the quality and the roughness requirements of the hole are improved, the organizing density of the interior of the hole is strengthened, pulling-out force (pulling-out face used for matching of a shaft and a hole) requirements of a product hole is greatly increased, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing and manufacturing, and in particular relates to a processing device for improving the surface and internal quality of holes in products. Background technique [0002] At present, the hole processing method is mainly to process holes in the form of boring or rolling cutters. During the boring process, the dimensional accuracy and roughness requirements of the finished holes cannot be effectively guaranteed, and when processing high-precision holes, Boring has a high reject rate. Contents of the invention [0003] The object of the present invention is to address the above problems and propose an improved device for processing holes. [0004] The main technical solution of the present invention: a device for processing holes, which is characterized in that it includes a hydraulic system, a control system and a processing system; hole. [0005] The main feature of the invention is to process...
