Numerical-control high-speed double grinding carriage axle shell grinding machine

Abstract

The invention provides a numerical-control high-speed double grinding carriage axle shell grinding machine. An adjustable multi-layer fixing headstock and a fixing tailstock are fixed at the left endand the right end of a workbench respectively, and the right end part of a workpiece which is supported on the workbench through a measuring instrument, brackets and hydraulic tracking center frames is jacked through a jacking tip on the fixing tailstock; the left end part of the workpiece is jacked through a headstock jacking tip in the adjustable multi-layer fixing headstock, an inner hole in the left end of the workpiece is tensioned through an inner expansion block at the right end of the adjustable multi-layer fixing headstock, and the workpiece is driven by a servo motor in the adjustable multi-layer fixing headstock to rotate; and compound feeding devices are arranged at the rear end of the upper plane of a machine tool body, and grinding machining of the left and right ends of theworkpiece is achieved through the composite feeding devices and grinding carriage grinding devices. According to the grinding machine, the double grinding carriage grinding machine structure is adopted to realize simultaneous grinding of the two ends of the workpiece, there is no need to turn the workpiece around in the grinding machining process, the defects of secondary clamping and turning grinding of the workpiece are eliminated, the grinding efficiency of the workpiece is improved, the grinding cost of the workpiece is low, and the workpiece grinding effect is good.

Description

technical field [0001] The invention belongs to the technical field of numerical control equipment, and in particular relates to a numerical control high-speed double grinding wheel bridge housing grinding machine. Background technique [0002] At present, when grinding the outer circle, end face and circular arc of the two ends of the axle head of the heavy-duty truck axle housing in China, the single-head grinding method is used, that is, the end face cylindrical grinder (that is, a single-head grinder) of a grinding wheel frame is used. A group of grinding wheels performs a forming grinding on the outer circle, end face and arc of the axle housing, and then manually turns around to grind the outer circle, end face and arc of the other end of the axle housing. The workpiece needs to be manually turned around once, and the production efficiency is low. At the same time, when the manipulator is connected to the line, an automatic line needs to be equipped with two single-he...

Problems solved by technology

The workpiece needs to be manually turned around once, and the production efficiency is low

At the same time, when the manipulator is connected to the line, an automatic line needs to be equipped with two single-head grinders, and each single-head grinder needs to adopt a hydraulic automatic tracking center frame with large-stroke movement to realize automatic loading and unloading on the single-head grinder. The manipulator makes a U-turn on the workpiece, resulting in a substantial increase in the manufacturing cost of the single-head grinding machine, and at the same time increasing the difficulty and cost of manipulator manufacturing. Therefore, it is necessary to improve the above problems
