A CNC machine tool for processing and deburring inner shaft parts

Abstract

The invention discloses a burring numerically-controlled machine tool for in-shaft part machining. The burring numerically-controlled machine tool for the in-shaft part machining structurally comprises a workbench, an electrical cabinet, a main machine box, a guider, a reamer and a rotary table, wherein the workbench is installed on the main machine box, the electrical cabinet is arranged on the workbench, the electrical cabinet and the main machine box are electrically connected, the guider, the reamer and the rotary table are fixed to the workbench, and an object bearing table, a supportingplate, a fixing port, a slide preventing strip, supporting leg mechanisms, a rotating shaft and supporting leg ports are arranged on the rotary table. According to the burring numerically-controlled machine tool, an accepting mode between the rotating shaft and the supporting plate is improved, the rotating shaft is composed of inner and outer shafts, the rotatable inner shaft is separated from the outside through the outer shaft, and the outer shaft is supported by a fan-shaped support formed by the supporting legs and the supporting leg ports, and the supporting leg mechanisms are sealed onthe bottom surface of the supporting plate while the supporting plate is stably supported, so that the characteristic of preventing flashes and burrs from falling into the rotating shaft under the condition of not influencing the normal operation of the rotary table is realized.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to a numerically controlled machine tool for processing and deburring inner-axis parts. Background technique [0002] The camshaft is one of the key parts of the engine gas distribution system. During the production process, the inner hole of the camshaft is prone to burrs. In order to ensure the quality of the product, it is necessary to remove the burrs in the inner hole of the camshaft. , There are flashes and burrs in casting and forging blanks made by molds, which have a certain impact on subsequent machining and appearance quality. Usually, these flashes and burrs need to be removed after the blank is formed. ; [0003] As a camshaft, a turntable is often used in deburring. The turntable can always ensure a more comprehensive deburring of the inner hole of the camshaft. However, as this function is carried out, the turntable is constantly rotating, and thes...

[0003] As a camshaft, a turntable is often used in deburring. The turntable can always ensure a more comprehensive deburring of the inner hole of the camshaft. However, as this function is carried out, the turntable is constantly rotating, and these flashes and burrs are affected by the wind force of the environment. Influenced by the impact, it falls on the transfer point of the turntable, and the uneven burrs sink deeper into the turntable with the continuous penetration, which affects the rotation of the turntable and wears more on the transfer position of the turntable.
