A Rotary Micro Blind Hole Cavitation Device

Abstract

The invention discloses a rotary micro blind hole emptying device in the field of emptying reinforcement machining. An output shaft of a driving motor is coaxially connected with a rotating shaft; a gear sleeves the rotating shaft; the gear is engaged with outer teeth arranged on the side wall of a base horizontally arranged; workpieces with micro blind holes are vertically placed in middle of thebase; the upper surfaces of the workpieces are tightly contacted and connected with an O-shaped cushion block with a center through hole; the upper surface of the O-shaped cushion block is tightly contacted and connected with a diaphragm; a sealing cavity is fully filled with liquid; the lower end of a diaphragm rod extends in from a through hole of a shell, and is fixedly connected with the diaphragm; the upper end of the diaphragm rod is contacted with the lower surface of the edge of an inclined disc; and the upper surface of the inclined disc is a horizontal surface, and the lower surfaceis an inclined surface having an included angle with the upper surface. A vertical moving worktable capable of moving up and down is arranged at the upper section of a vertical worktable base, and isfixedly connected with the inclined disc through a bracket; and through uniform-speed rotation of the diaphragm rod on the inclined disc, the diaphragm performs a reciprocating motion to form emptying.

Description

technical field [0001] The invention belongs to the field of cavitation strengthening processing, and in particular relates to a device for processing tiny blind holes with a diameter less than 2mm. Background technique [0002] The types of parts or components are developing in the direction of densification, complexity and miniaturization, and there is an increasing demand for workpieces with high-quality blind micro-hole structures. For workpieces with micro-blind hole structure, it is usually necessary to strengthen the surface of the inner hole to improve its service life. However, due to the limitations of the structure of micro-blind holes and the interference of processing tools, traditional mechanical shot peening and cold extrusion processing technologies are difficult to process this type of workpiece to meet the requirements of the industrial field. The mechanical shot peening technology uses tiny projectiles as the working medium, uses high-pressure wind or com...

Problems solved by technology

[0003] The purpose of the present invention is to provide a rotary micro-blind hole cavitation device, which constantly changes the size of the micro-blind hole to be strengthened by using the reciprocating movement of the diaphragm. The liquid volume is sealed in the hole, which realizes the cavitation of the micro-blind hole, thereby strengthening its surface
