High-precision vertical type machining center

Abstract

The invention discloses a high-precision vertical type machining center comprising a pedestal, an upright column, a worktable, a spindle case, a PLC controller, a machining spindle component, a Y-axis movement mechanism, an X-axis movement mechanism and a Z-axis movement mechanism. The worktable comprises a saddle, a worktable plate, a telescopic protecting cover, and a sliding rail extension bracket. The saddle is installed on the Y-axis movement mechanism. The X-axis movement mechanism comprises a linear sliding rail and a sliding block. One end of the telescopic protecting cover is connected with the worktable plate; the other end is connected with the sliding rail extension bracket. The high-precision vertical type machining center is reasonable in structural design. An automatic control is conducted by the PLC controller, and the purpose of the automatic machining can be achieved by clamping once, with fast machining speed, high precision and good working stability. Moreover, by reasonably designing the worktable, the rigidity and the stability of the entire structure are increased, thereby effectively reducing the vibration. With the high machining precision, the stable running, and the good protecting effect, the cutting chips or other foreign materials are effectively prevented from dropping onto the guide rail, thus the service life is long.

Description

technical field [0001] The invention relates to the technical field of machining centers, in particular to a high-precision vertical machining center. Background technique [0002] Machining centers are developed from CNC milling machines. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through an automatic tool changer in one clamping to achieve a variety of machining. Features. [0003] Although the existing machining center can meet the needs of machining and use, its structure is relatively complex, bulky, and large in size, which brings inconvenience to installation and maintenance; and the machining center will generate chips during the work process, in order to prevent the chips from entering the guide rail It will cause wear between the workbench and the guide rail, ...

Problems solved by technology

[0003] Although the existing machining centers can meet the needs of machining and use, their structures are relatively complex, bulky, and large in size, which brings inconvenience to installation and maintenance; moreover, machining centers will generate chips during the working process. To prevent the chips from entering the guide rail Cause wear between the workbench and the guide rail, it is usually necessary to set a protective cover on the idle section of the guide rail

However, the protective cover in the current technology has no special supporting parts to cooperate, resulting in poor working stability and poor protection effect. Chips are easy to fall on the guide rail, causing unnecessary abnormal noise, and also causing vibration of the workbench, resulting in The machining accuracy of the machining center is reduced
