Abstract

The invention relates to a boring device for multiple sets of long-spacing coaxial holes. The boring device for multiple sets of long-spacing coaxial holes comprises a three-phase asynchronous motor, a cycloidal-pin wheel speed reducer, a movable carriage, a fixed carriage, a T-shaped screw rod, a T-shaped copper nut, an axial thrust bearing, a longitudinal movable adjusting nut, a boring rod fixing base A, a boring rod fixing base B, a thrust bearing ,a small gear, a large gear, a radial bearing, a boring rod, a boring machine fixing rod and the like. The boring device fixing rod is pressed on a tool rest on any side of a double housing planer, the tool rest can move horizontally and vertically, the moving distance is accurately determined through a dial indicator, and the boring coaxiality is high; coaxiality and roundness tolerance of holes can meet design requirements; and the boring device is suitable for machining holes with various types of spacing and with the high requirement for coaxiality.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing engineering, and in particular relates to a boring device for processing multiple groups of steel components with high requirements on coaxiality and roundness and long processing distance. Background technique [0002] At present, in the process of mechanical finishing, it is often encountered that large workpieces need to bore multiple sets of holes with high coaxiality requirements, and the distance between holes is long. Generally, the length of ordinary boring machines cannot exceed the effective feed distance. That is to say, ordinary boring machines cannot realize long-distance hole processing with high coaxiality requirements. If special equipment is purchased for this processing, it is neither in line with market efficiency nor in line with the business philosophy of the enterprise, and the cost is high, so it cannot be promoted. application.
