Abstract

The invention discloses a sleeve barrel structure of a horizontal type numerical control boring-milling machine. A sleeve barrel is installed in a fixed sleeve, the inside of the sleeve barrel is provided with a boring bar, a balancing sleeve is arranged between the sleeve barrel and the fixed sleeve and is connected with the sleeve barrel by double keys, and the double keys are fixed on the sleeve barrel by screws; and both ends of the balancing sleeve are respectively provided with duplex bearings, the duplex bearings are spaced by a bearing sleeve, and the bearing sleeve is sleeved at the outside of the balancing sleeve. The invention has the beneficial effects that the balancing sleeve is additionally arranged and has the function of carrying out fine adjustment to an axle, and automatic centering is realized in the running process of the sleeve barrel, so that the effects of balancing and stability are achieved; and simultaneously, the vibration of a main shaft can be reduced, the rotary inertia of the main shaft is increased, and the processing precision of a boring-milling shaft is improved.

Description

technical field [0001] The invention relates to a sleeve structure of a horizontal numerical control boring and milling machine, in particular to a sleeve structure sleeved on a boring bar of a horizontal numerical control boring and milling machine. Background technique [0002] At present, the structure and design scheme adopted by the domestically produced boring and milling machine equipment were imported from the Soviet Union decades ago. In this field, my country does not have completely independent intellectual property rights. As a large manufacturing country, boring and milling machines are often used in the fields of machining and manufacturing. At present, the high-end boring and milling machine equipment used in my country generally needs to be imported from abroad. In this way, since we cannot produce the boring and milling machine equipment that meets the needs of domestic production and processing, the development of domestic related industries is often subj...
