Vertical lathe tool holder upside-down hanging milling transmission mechanism

Abstract

The invention discloses a vertical lathe tool holder upside-down hanging milling transmission mechanism which comprises a transmission arm. A main transmission case is fixedly arranged at the top endof the transmission arm; a motor is fixedly arranged on one side of the bottom end of the main transmission case; an outer wall of the main transmission case is fixedly connected with a soundproof boxthrough a fixing block; a gas distributing pipe is fixedly arranged in the soundproof box; and a gas outlet end of the gas distributing pipe communicates with the inner part of the main transmissionbox. According to the vertical lathe tool holder upside-down hanging milling transmission mechanism provided by the invention, a closing direction of a milling tool motor is downward, so that the height of a whole vertical lathe tool is effectively reduced, the problem that a workshop hoisting crane and the milling tool motor are easily interfered when a user workshop lifting frame is not high enough is effectively solved, and the occurrence of safety production accidents is greatly avoided; external air is extracted into the main transmission case through an exhaust fan so as to blow air andradiate heat for parts in the main transmission case; and meanwhile, the air is filtered through a filter mechanism.

Description

technical field [0001] The invention belongs to the technical field of lathes, and relates to a transmission mechanism, in particular to an upside-down milling transmission mechanism of a tool holder of a vertical lathe. Background technique [0002] The tool holder is a very important part of the CNC lathe. According to its function, the number of tools that can be installed on the tool holder is generally 4, 6, 8, 10, 12, 20 and 24, and some CNC lathes can install more tools. The structure of the tool holder is generally rotary, and the tool is installed on the tool holder along the circumferential direction, and radial turning tools, axial turning tools, drills, and boring tools can be installed. Turning machining centers can also be equipped with axial milling cutters and radial milling cutters. The tool holders of a small number of CNC lathes are in-line, and the tools are installed along a straight line. [0003] However, because the existing vertical turning tool p...
