Inside surface milling equipment

Abstract

The invention provides inside surface milling equipment. The equipment mainly comprises a casing, and the right end of the casing is provided with a rotating column which can extend into a processingpiece; the rotating column is internally provided with a rotating cavity, and the upper and lower end walls of the rotating cavity are provided with two symmetrical rotating mechanism; each rotating mechanism comprises an abutting block, and the rotting cavity is internally provided with a transmission shaft; the abutting blocks can be tightly attached to the transmission shaft, and rotated with the transmission shaft; the transmission shaft is driven to rotate for achieving rotation of a milling part, and the rotating cavity is internally provided with a fixing base which can be used for fixing a milling cutter; the transmission shaft is rotated for driving the milling cutter to rotate for milling, and the casing is internally provided with a movable block connected with the transmissionshaft rotatably; the lower side of the movable block is provided with a moving mechanism which can be used for moving the movable block, and horizontal movement of the milling part is achieved; and the casing is internally provided with a driving mechanism used for providing power for rotation of the transmission shaft and movement of the moving mechanism. According to the inside surface milling equipment, the inside surface of the processing piece can be milled, and the milling cutter can be used for milling the processing piece under the control of a computer numerical control milling machine in any direction.

Description

Technical field [0001] The invention relates to the technical field of milling, in particular to an inner surface milling processing equipment. Background technique [0002] The milling machine is a wide range of machine tools. On the milling machine, it can process planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), gear parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the revolving body and cut off the work. [0003] However, the inner surface of the set workpiece cannot be processed well due to the structural limitation of the existing milling machine. For example, the inner surface of the metal sleeve needs to be processed with a certain shape of grooves. The existing metal is usually processed in the form of a planer. The inner surface of the casing, but this processing method is not only inefficien...

Problems solved by technology

[0003] However, for the inner surface of the set workpiece, due to the structural limitations of the existing milling machine, it cannot be processed well. For example, the inner surface of the metal sleeve needs to be processed with a groove of a certain shape. Currently, the metal is usually processed in the form of a planer. The inner surface of the casing, but this processing method not only has low efficiency and low processing accuracy, but also cannot process threaded grooves
