Steerable micro drilling and milling device used for workpiece inner and outer cavity processing

Abstract

The invention discloses a steerable micro drilling and milling device used for workpiece inner and outer cavity processing. The steerable micro drilling and milling device comprises a connecting frame, a gearbox, a transmission mechanism and a detachable tool structure, wherein the connecting frame comprises an upper double-layer ring body connected with a vertical type milling machine main shafthousing and a lower cylinder; the transmission mechanism is arranged in the gearbox; the transmission mechanism comprises a transmission shaft, an output shaft, a drive bevel gear and a driven bevel gear; a tapered shaft section of the transmission shaft extends out of the cylinder and is mounted on the main shaft of the vertical type milling machine; the drive bevel gear is in transmission connection on the transmission shaft through a key; a tool mounting section of the output shaft leftwards extends out of an output shaft mounting barrel; the detachable tool structure is mounted on the toolmounting section of the output shaft; and the driven bevel gear is in transmission connection on the output shaft through a key. The steerable micro drilling and milling device can be assembled ontothe vertical type milling machine to complete processing processes of drilling holes, milling small steps, milling inner molded surfaces and the like for workpiece inner and outer cavities, is compactin structure, is convenient to dismount, expands the processing range of the vertical type milling machine, and improves processing efficiency and processing precision.

Description

Technical field [0001] The invention belongs to the field of tool clamping of machine tools, and relates to a micro-drilling and milling device for machining inner and outer cavities of a workpiece. Background technique [0002] With the development of society and actual needs, people’s requirements for the performance of mechanical appliances are constantly increasing, and the geometric shapes of mechanical parts and finished products are becoming more and more complex. Processing with internal and external cavities of workpieces has always been a difficult point in the field of mechanical manufacturing. Machining is almost impossible on a three-axis machine tool. In traditional processing and manufacturing, methods such as casting, turning or wire cutting are often used. These methods have low processing efficiency, poor casting accuracy, complex turning processes and require multiple clamping, and the wire cutting cavity structure must be a through hole. A series of problems ...
