Abstract

The invention discloses a vertical lifting platform numerically controlled fraise machine applicable to heavy cutting, which comprises a body and a ram arranged on the body, wherein a cutter head is fixedly arranged on the ram, a spindle motor is arranged on the cutter head, the body is provided with an upright guide rail, a lifting platform, a saddle, a workbench, a spindle automatic servo feeding mechanism, a lifting platform electric lifting mechanism and an electric cabinet, wherein the spindle automatic servo feeding mechanism and the lifting platform electric lifting mechanism are used for driving the workbench, the lifting platform is driven by the lifting platform electric lifting mechanism to lift; and the body also comprises a cylindrical auxiliary guide rail arranged on the body, the lifting platform is a cantilever beam mechanism, is arranged on the upright guide rail and the cylindrical auxiliary guide rail and is driven by the lifting platform electric lifting mechanism to lift. The rigidity of the vertical lifting platform numerically controlled fraise machine is good, and the technical problems of the existing cutter head that a cutter bit is easy to deflect or thebody is easy to shake when the cutting output is a little large in the machining process of the cutter head and the body can be effectively solved.

Description

technical field [0001] The invention relates to a milling machine, in particular to a vertical lifting table numerical control milling machine suitable for heavy cutting. Background technique [0002] Due to the relatively scattered structure and the composition of the transmission mechanism, the existing CNC milling machine has poor overall rigidity, especially due to the structure of the column guide rail, there is not enough rigidity to resist the torsion and bending caused by the cutting force. When the amount is slightly larger, the milling head will vibrate strongly, affecting the machining accuracy, and it is difficult to achieve high-efficiency machining with a large cutting amount. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vertical lifting table CNC milling machine with stable performance, high machining accuracy and high positioning accuracy suitable for heavy cutting in view of the problem that...
