High-precision grinding numerical control grinding machine

Abstract

The invention discloses a high-precision grinding numerical control grinding machine, particularly relates to the technical field of numerical control grinding machines. Through the adoption of the technical scheme, the high-precision grinding numerical control grinding machine comprises a gearbox, a gear lever and a supporting arm, wherein a second positioning seat is fixedly mounted on the inner wall of the gearbox, a high-speed gear ejector rod, a medium-speed gear ejector rod and a low-speed gear ejector rod are inserted into the inner wall of the left end of the second positioning seat, the gear lever is inserted into the inner wall of the gearbox, a small gear, a middle gear and a large gear are fixedly mounted on the outer wall of the gear lever, the large gear is connected with the high-speed gear ejector rod, the outer wall of the gear lever is sleeved with a pull ring, a top seat is fixedly mounted on the inner wall of the gearbox, a second sliding groove is formed in the inner wall of the top seat, and a pull block is inserted into the inner wall of the second sliding groove. The high-precision grinding numerical control grinding machine has the beneficial effects that a grinding table can be adjusted in a lifting mode according to different precision by arranging three precision adjusting devices on the grinding table, air is blown to a grinding head, the grinding head is kept clean all the time, and objects can be ground in a high-precision mode.

Description

technical field [0001] The invention relates to the field of numerical control grinding machines, in particular to a numerical control grinding machine for high-precision grinding. Background technique [0002] CNC grinding machine is a machine tool that uses abrasive tools to grind the surface of workpieces through numerical control technology. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones, abrasive belts, and free abrasives for processing. , such as honing machines, ultra-finishing machine tools, abrasive belt grinders, grinding machines and polishing machines, etc. CNC grinding machines also include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders, CNC forming Grinding machines, etc. CNC machine tools are the product of the combination of information technology and mechanical manufacturing techno...
