Five-shaft moving-column-type numerically controlled milling machine

Abstract

The invention discloses a five-shaft moving-column-type numerically controlled milling machine which comprises a full-support moving-column-type body, a self-locking type index dial and a pedestal. The full-support moving-column-type body, arranged at one side of the pedestal, comprises a saddle which is in slide connection with the upper surface of the pedestal and slides along an X-axis direction, a column which is in slide connection with the upper surface of the saddle and slides along a Y-axis direction, a head portion which is arranged at the column and slides along a Z-axis direction, and a rotary main shaft arranged in the head portion. The self-locking type index dial, arranged at the other side of the pedestal, comprises an index dial, an up-and-down turning device, a horizontally-rotating device, a clamping device and a index dial stand, wherein the index dial is arranged on the index dial stand, the up-and-down turning device can control the index dial to rotate 90 DEG up and down, the horizontally-rotating device can control the index dial to rotate 360 DEG horizontally, and clamping device is used to fix the horizontally-rotated index dial. The machine can ensure processing quality of tyre die, and meanwhile greatly improve production efficiency.

Description

technical field [0001] The invention relates to an improvement of a numerically controlled milling machine, in particular to a five-axis movable column numerically controlled milling machine capable of improving the processing precision and efficiency of tire molds, and belongs to the technical field of mechanical processing equipment. Background technique [0002] At present, in the existing tire mold processing equipment, the EDM machine is basically used to process the tire pattern. Although the use of the EDM machine can ensure the roughness of the tire mold cavity, it takes a lot of money for this processing mode. It takes a long time to complete the processing of a set of tire molds. Therefore, applying the processing mode of the machine tool structure of the machining center to the tire mold processing equipment, and adopting high-speed and high-precision milling methods for fast milling can greatly shorten the processing time of tire molds and meet the high-precision...

Problems solved by technology

In traditional machine tool processing, vertical machining centers are generally used to complete the milling of workpieces. With the continuous development of machining technology, some weaknesses of vertical machining centers have become more and more obvious. Modern mold processing generally uses ball milling. The benefits of ball end milling cutters in mold processing are very obvious, but if a vertical machining center is used, the linear speed of the bottom surface is zero, so the finish of the bottom surface is very poor, and for complex curved surfaces Processing sometimes requires multiple clamping, which greatly reduces the machining accuracy, and some molds with special contour shapes will use special clamping tools and special tools to complete the processing, which greatly increases the processing cost
