Main spindle box for milling and drilling machine

Abstract

The invention relates to a main transmission box for a milling and drilling machine. The main transmission box comprises a sealed cavity composed of a box body and a box cover, and an input shaft component, a transmission shaft component and an output shaft component are mounted in the sealed cavity. The main transmission box is characterized in that a gear shaft is rotatably mounted in the sealed cavity, a main shaft motor is mounted on the sealed cavity, an output shaft of the main shaft motor is connected with the gear shaft; the transmission shaft can be rotatably mounted in the sealed cavity, and a high-low-drive gear set is assembled on the transmission shaft in a sliding manner; a large transmission gear in the high-low-drive gear set is always engaged with a gear shaft in the input shaft component; the main shaft can be rotatably mounted in the sealed cavity, a large output gear and a small output gear are mounted on the main shaft; a main shaft broaching-loosening cutter is arranged in the main shaft for firmly grasping a cutter. The transmission shaft box has rational and clever structure, and can meet a high output torque demand of the main shaft milling processing and a high output rotation speed demand of the drilling processing, can effectively meet the milling-drilling composite processing demands of parts. By the adoption of the transmission shaft box, the working efficiency can be obviously improved and the processing precision can be ensured.

Description

Technical field [0001] The present invention involves a special proportion of the milling diamond machine used in the CNC milling and drilling machine, which is a mechanical structure technology field. Background technique [0002] With the development of large -scale equipment manufacturing industries, the performance requirements of large CNC machine tools in the market are getting higher and higher. Machine tool equipment with single processing production functions is increasingly unable to meet the processing needs of complex components.EssenceThe composite machining machine tool is two or more processing functions on one processing equipment. The production process that needs to be completed by two or more processing machine tools before completing one processing equipment can be greatly improved.efficiency. [0003] The milling processing of the machine tool mainly relies on the output torque of the main axis, and the speed requirements of the main axis during drilling proc...

Problems solved by technology

[0002] With the development of large-scale equipment manufacturing industry, the performance requirements of large-scale CNC machine tools are getting higher and higher in the market. Machine tool equipment with only a single processing and production function can no longer meet the processing needs of complex parts, and it is replaced by compound processing machine tools.
