Upright post structure of horizontal type numerical control boring-milling machine

Abstract

The invention discloses an upright post structure of a horizontal type numerical control boring-milling machine, comprising upright posts, a pulley rack and a balancing weight hammer, wherein the pulley rack and the balancing weight hammer are installed on the upright posts, the upright posts are integrally formed and are arranged by adopting a portal frame type, V-shaped guide rails connected with a slide block are arranged on the double upright posts, and lead screw holes are arranged on transverse beams on the tops of the upright posts and are provided with lead screws which are used for driving the slide block to move along the guide rails; post bodies are hollow, and the inner sides of the post bodies are provided with a plurality of strengthening ribs; the balancing weight hammer has a structure of double weight hammers, and the balancing weight hammer and the slide block are hung and connected on the pulley rack; and the two weight hammers of the balancing weight hammer are respectively arranged at a hollow position inside an upright post main body, the inside of the main body is provided with a guided way, and a way groove matched with the guided way is arranged on the balancing weight hammer. The invention has the beneficial effects that the whole weight bearing is more uniform, and the structure of the double upright posts also causes the entire system to be more stable; and the invention has convenient use and maintenance, reasonable layout and low manufacturing cost and is safe and reliable.

Description

technical field [0001] The invention relates to a horizontal numerically controlled boring and milling machine, in particular to a column structure of the horizontal numerically controlled boring and milling machine. Background technique [0002] At present, the structure and design schemes adopted by domestically produced boring and milling machines were imported from the Soviet Union decades ago. In this field, my country does not have completely independent intellectual property rights. As a big manufacturing country, boring and milling machines are frequently used in machining, manufacturing and other fields. At present, the high-end boring and milling machine equipment used in my country generally needs to be imported from abroad. In this way, because we cannot produce boring and milling machine equipment that meets the needs of domestic production and processing, the development of related domestic industries is often subject to foreign technology. Especially those ...
