A Narrow Deep Cavity Track Type Multi-Power Head Processing Device

Abstract

The invention discloses a narrow and deep cavity rail-mounted multi-power head machining device. The narrow and deep cavity rail-mounted multi-power head machining device comprises a guide rail, a bottom frame, a longitudinal shaft moving feeding mechanism and a machining module. The longitudinal shaft moving feeding mechanism and the machining module are both installed on the bottom frame. The longitudinal shaft moving feeding mechanism coordinates with a rack on the inner side of a guide rail base on a machine tool through a gear to achieve longitudinal precise movement of the machining module. The longitudinal shaft moving feeding mechanism takes part in multi-axis linkage to achieve precise insertion supplementing movement of the machining module. According to the narrow and deep cavity rail-mounted multi-power head machining device, the machining module comprises a plurality of functional modules with different machining characteristics, efficient machining with various machiningcharacteristics can be achieved, and the application range of the machining device is greatly enlarged. According to the narrow and deep cavity rail-mounted multi-power head machining device, a pneumatic motor serves as machining main shaft drive, an air cylinder is used for carrying out vertical feeding, relative to electric main shaft and motor drive feeding, the narrow and deep cavity rail-mounted multi-power head machining device has the beneficial effects that at the same power, the size and the length of the pneumatic motor are far smaller than those of an electric motor, the speed reducer design is omitted in the drive part, and the size of the related whole device is greatly reduced.

Description

Technical field [0001] The invention belongs to the field of aerospace processing, and relates to a narrow deep cavity orbital multi-power head processing device. Background technique [0002] There are more and more integrated processing requirements for large components in the aerospace field. Components such as cabin sections and cylinders usually need to be milled and hole-made after integral molding to meet the requirements of component connection and assembly. The processing position is usually located in the inner wall of the deep cavity in a narrow space, which is not convenient for automated processing. It is usually processed by manual processing by workers. The inner cavity of the component is narrow and the worker's working environment is harsh. [0003] At present, for the processing of deep cavity components, long cantilever extension type and spindle through type processing equipment are mainly used. Long cantilever extension type structure is difficult to process an...

Problems solved by technology

[0004] Narrow and deep cavity orbital processing devices are usually used in the field of connection and assembly of aerospace equipment, but because of their targeted design, often a processing device can only achieve one processing method, such as a single drilling or a single boring , and the volume of multi-axis equipment is large, so it is difficult to use
